Security system

Description: TECHNICAL FIELD [Detailed description of the invention]

【0001】

[Technical field to which the invention belongs]

The present invention relates to a security system that protects the safety of residences and offices and the safety of persons requiring nursing care by using a communication network such as the Internet.

[Conventional technology]

Various security systems have been developed to ensure the security of residences and offices. A typical example is a security system built by a so-called security company. In this type of security system, a sensor that detects the occurrence of an accident is installed in the client's residence or office, and the client's residence and the security company are connected via a communication line, causing some incident at the site. When the security company senses that the problem has occurred, it issues a command to the patrol car that is patrolling the area including the client's whereabouts so that the security guards can rush to the scene.

【0002】

In addition, a security system has been developed with the same configuration that dispatches a nurse when something goes wrong with an elderly or sick person at home who needs long-term care.

【0003】

In this specification, the term "security" refers to measures such as preventing a suspicious person from invading the client's residence when the suspicious person is trying to invade, or requesting an ambulance to be dispatched when the condition of an old man or sick person suddenly changes. Measures necessary to protect the client, the client's family and other related parties, and the client's property, etc., in the event of any change in the client's whereabouts, such as taking measures or contacting the fire department in the event of a fire. Means to take.

【0004】

[Problems to be Solved by the Invention]

As described above, in the conventional security system, the occurrence of an accident at the site is detected by some kind of sensor, but it is difficult to reliably determine the presence or absence of the occurrence of an accident only by relying on the sensor. For example, when an infrared sensor or the like is used to detect the invasion of a suspicious person, it is difficult to clearly distinguish the invasion of a suspicious person from the invasion of a small animal such as a cat or a dog. In addition, a sensor that detects the movement of the long-term care recipient is provided to determine that the condition of the long-term care recipient has changed when the long-term care recipient has stopped moving for a certain period of time. Then, it is difficult to surely grasp the condition of the person requiring long-term care.

【0005】

In this way, it was difficult to accurately grasp the situation at the site with the conventional security system that only relied on the sensor to grasp the situation at the site. There was a problem that it became necessary to start security activities such as dispatching, and the probability that security activities would be wasted increased. Unnecessary security activities are not desirable because they not only force the client to waste money, but also delay the urgent and truly necessary security activities.

【0006】

It is also possible to reduce the sensitivity of the sensor in order to reduce the probability of unnecessary security activities, but if this is done, it will not be possible to detect the occurrence of an accident without omission, so the purpose of security should be achieved. Becomes difficult.

【0007】

In addition, in order to reliably determine whether or not an accident has occurred in a place requiring security, an image sensor such as a television camera should be installed at the site, and the image of the site obtained from this image sensor should be monitored by a security company or the like. However, it is virtually impossible for a security company or the like to continuously monitor images of a large number of clients at the site requiring monitoring all day long.

【0008】

In addition, in the conventional security system, when it is detected that an accident such as an intrusion of a suspicious person or a sudden change in the condition of a person requiring nursing care has occurred, a security company or the like issues a command to a patrol vehicle patrolling the vicinity of the site. Therefore, security guards and other security personnel were rushed to the site, but since patrol vehicles are patrolling a relatively wide area, they arrive at the site after receiving a command depending on the traffic conditions near the site. It often takes a considerable amount of time to do so, and during that time, damage such as theft may occur, or the medical condition of the person requiring care may be too late.

【0009】

One object of the present invention is to provide a security system capable of reliably detecting the presence or absence of an accident at a site requiring monitoring and preventing unnecessary security activities from being performed. To do.

【0010】

Another object of the present invention is that after an accident occurs at a site requiring monitoring, damage such as theft may occur before the security officer arrives at the site, or the condition of the person requiring care may be too late. The purpose is to provide a security system that can reduce the risk.

【0011】

[Means for solving problems]

The present invention does not rely only on the monitoring device installed in the field, but makes the client himself / herself judge whether or not an accident has occurred when the occurrence of an abnormality is suspected. It is characterized by improving sexuality and reducing the probability of unnecessary security activities.

【0012】

Therefore, in the basic configuration of the present invention, the monitoring / terminal device installed in the client's residence or office, and the client's mobile terminal device that the client carries when going out are connected to these via a communication network. Build a security system with the security server.

【0013】

The monitoring / terminal device used in the present invention is preferably based on a monitoring device that detects information on a site requiring monitoring that needs to be monitored in order to achieve the security desired by the client, and information on the site detected by this monitoring device. The situation change detecting means for detecting the presence or absence of a change in the situation at the site requiring monitoring and the site information detected by the monitoring device when the situation change detecting means detects a predetermined change in the situation at the site requiring monitoring are sent to the security server. The configuration is provided with a fixed terminal device for a client having a means for transmitting on-site information to be transmitted.

【0014】

In this case, the security server transmits the site information transmitted from the fixed terminal device for the client to the mobile terminal device for the client to prompt the client to reply with the help request signal, and the help request reply request means for the client and the client. The configuration is provided with a security officer dispatch request processing means that performs a process for requesting the security personnel to start security activities when a help request signal is returned from the mobile terminal device for use.

【0015】

In this specification, the term "whereabouts" is used to include both an address and a place of residence (for example, an office or a store) which means a place where a person stays for a considerable amount of time, although it is not an address.

【0016】

The above-mentioned security officer may be a security officer such as a security guard company, a nursing service company, or a security guard belonging to an organization such as a hospital with which the client has a contract. It may be a helper selected from those registered as helper personnel.

【0017】

The monitoring device needs to be able to provide a client with information suitable for grasping the situation at the site with the mobile terminal device. The information (site information) suitable for the client to grasp the situation of the site by the mobile terminal device is, for example, an image showing the situation of the site requiring monitoring, a voice generated at the site, or the like.

【0018】

The most suitable information to be provided to the client in order to ensure the determination of the presence or absence of an accident is an image showing the situation at the site requiring monitoring. Therefore, it is desirable that the monitoring device used in the present invention is an image sensor that captures an image of a site requiring monitoring and detects an image of the site as site information, or a combination of the image sensor and another sensor.

【0019】

Other sensors combined with the image sensor differ depending on the purpose of security. For example, when the purpose is to prevent the intrusion of a suspicious person (crime prevention), it is preferable to use an intrusion sensor using infrared rays, a sensor that senses the sound of the site, or the like as the above-mentioned other sensors. For the purpose of caring for the sick or the elderly, sensors that detect the movement of humans by detecting infrared rays generated from the human body (pyroelectric sensors, etc.) and sensors that detect the sound of the site are the above-mentioned other sensors. It is preferable to use as.

【0020】

When an image of the site is used as the site information, this image is preferably a moving image, but it is a still image (intermittently capturing the situation of the site) obtained by capturing the site at regular intervals. There may be.

【0021】

In the present invention, when it is detected from the site information detected by the monitoring device that a predetermined change in the situation has occurred at the site, the site information is transmitted to the mobile terminal device of the client. Therefore, it is necessary to provide a means (situation change detecting means) for automatically detecting a change in the situation at the site without relying on a person.

【0022】

When an image sensor is used as the monitoring device, changes in the situation at the site can be detected by processing the image signal obtained from the image sensor with the fixed terminal device for clients.

【0023】

The sites requiring monitoring that need to be monitored for security purposes shall be set appropriately according to the purpose of security. For example, when security against crimes such as theft and arson (crime prevention) is used, and when an image sensor is used as a monitoring device, it is preferable to set the site (garden, etc.) around the building as a monitoring site. In addition, when the purpose of security is to care for the elderly or sick, the living room of the elderly or sick who needs nursing care should be the place to be monitored.

【0024】

As described above, in the present invention, when it is detected that some change in the situation has occurred at the site, the information of the site detected by the monitoring device is transmitted to the mobile terminal device of the client, and the client itself is changed. Since the presence or absence of the occurrence is determined, it is possible to ensure the detection of the occurrence of an accident and prevent unnecessary security activities from being carried out.

【0025】

In the above configuration, the change in the situation at the site is detected by the fixed terminal device for the client, but when the fixed terminal device for the client and the server are always connected, the change in the situation at the site is detected by the server. It may be detected on the side.

【0026】

In this case, the security server has a situation change detecting means for detecting whether or not there is a change in the situation at the site requiring monitoring from the site information transmitted from the fixed terminal device for the client, and the situation change detecting means has the situation at the site requiring monitoring. When it is detected that a predetermined change has occurred in the client, the on-site information sent from the fixed terminal device for the client is sent to the mobile terminal device for the client to prompt the client to reply with the help request signal. The configuration includes a requesting means and a security activity request processing means for requesting the security personnel to start the security activity when a help request signal is returned from the mobile terminal device for the client.

【0027】

In order to prevent damage such as theft or deterioration of the sick person's condition before the patrol car arrives at the client's residence, register helper personnel who will cooperate with security activities. When it is confirmed that an incident has occurred in the client's whereabouts, it is preferable to request the helper selected from the helper personnel near the client to be dispatched.

【0028】

In the present invention, when the helper is used as described above, the monitoring / terminal device installed in the client's residence or office, and the client's mobile terminal device to be carried when the client goes out are registered. A security system is constructed by a helper terminal device to be provided to each of a plurality of helper personnel, and a security server connected to a monitoring / terminal device, a client mobile terminal device, and a helper terminal device via a communication network. Is preferable.

【0029】

In this case, the security server includes at least one helper among the helper personnel registered when the help request signal is returned from the client mobile terminal device, among the helper personnel who have a residence near the client's residence. A helper selection means for selecting and a help command means for transmitting a help command including a dispatch command to the client's whereabouts and geographical information of the client's whereabouts are provided to the helper mobile terminal device possessed by the selected helper.

【0030】

Even when requesting the dispatch of a helper as described above, the change in the situation at the site requiring monitoring may be detected by the client terminal device or the security server side.

【0031】

As described above, if a helper who has a residence near the client is requested to be dispatched when an accident occurs at the site requiring monitoring, the helper can arrive at the site in a short time. Therefore, for example, the client's whereabouts. When a suspicious person is about to invade, the suspicious person can give up the invasion and prevent the crime.

【0032】

In addition, if an abnormality occurs in a sick person or an elderly person, a helper who rushes to the site will check the situation and, if necessary, request an ambulance to be dispatched. Security measures can be taken in time. In this case, if an experienced nurse or a doctor is selected as a helper, the purpose of security can be achieved more accurately.

【0033】

When selecting a helper, a certain distance from the client's whereabouts should be taken into consideration, such as the past cooperation level (= number of cooperation / number of requests) of registered helper personnel and the content of incidents occurring at the site. It is good to select a person who has a place of residence in the range and whose past cooperation level is above a certain level as a helper.

【0034】

In addition, when a qualified person such as a doctor or a nurse is used as a helper, such as for the purpose of nursing care, or when it is necessary to leave the key of the client's whereabouts to the helper, each client On the other hand, it is preferable to determine the helper personnel in advance and select the helper personnel as helpers.

【0035】

【0046】

As a matter of course, a large number of client and helper personnel are registered, but in FIG. 1 and FIG. 2 shown below, for the sake of simplicity, one client and one helper personnel are assigned to each of the client side and the helper personnel. The configuration on the helper staff side is illustrated.

【0047】

(2) Configuration and operation of equipment installed at the client's residence FIG. 2 is an explanatory diagram showing the configuration of the security system according to the present invention, centering on the configuration of the security server, together with various processes performed in the system. In the figure, the processes S1 to S9 indicated by the solid arrows are the processes that are sequentially performed online, and the processes A to E indicated by the dashed arrows are the processes that are performed offline.

【0048】

In the example shown in Fig. 2, the purpose of security is to prevent crime at the client's home. Therefore, in this example, a plurality of television cameras (hereinafter, simply referred to as cameras) are used as image sensors so that the garden around the client's house 20 can be monitored without omission. ) C1, C2, ... are installed. In addition, an intrusion detector that detects an intruder (or animal) in the field of view of each camera is provided for each camera, and monitoring is required by these multiple cameras and the intrusion detector. A monitoring device 1A that detects on-site information is configured.

【0049】

As the intrusion detector, already known ones such as one that outputs a detection signal when an intruder blocks infrared rays and one that detects infrared rays generated by an intruder can be used.

【0050】

The camera that captures the garden around the house is preferably installed in an inconspicuous place such as under the eaves of the house.

【0051】

When trying to prevent crime, it is preferable to be able to monitor the site requiring monitoring even at night. Therefore, a night-vision camera can be provided, but since the night-vision camera is expensive, in order to reduce the cost of the equipment, an area that enters the field of view of each camera when an intruder is detected by the intrusion detector. It is preferable to take the method of illuminating the camera. For that purpose, for example, an illumination lamp is provided to illuminate the area in the field of view of each camera, and when the intrusion detector corresponding to each camera detects an intruder, the area in the field of view of each camera is illuminated. The device may be turned on. If the lighting device is turned on when an intruder is detected, the effect of repelling the intruder can be expected.

【0052】

Image signals (moving image signals) output by a plurality of cameras constituting the monitoring device 1A are input to the client fixed terminal device 1B installed in the house 20 through a switching circuit (not shown). The switching circuit is a circuit that selects one of a plurality of cameras C1, C2, ... In response to a selection command given from the terminal device 1B and gives the output of the selected camera to the terminal device 1B.

【0053】

The fixed terminal device 1B for the client gives a selection command to the switching circuit so as to sequentially select and capture the image signals output by the plurality of cameras C1, C2, ... When in the security operation mode. Then, the outputs of multiple cameras are sequentially captured. The terminal device 1B detects whether or not there is a change in the situation at the site requiring monitoring from the presence or absence of a change in the image signal obtained from each camera.

【0054】

The fixed terminal device 1B for clients is obtained from a camera that detects a predetermined change in the field situation that is suspected of being invaded by a suspicious person (for example, when a change in an image signal is detected). After compressing the moving image signal with the MPEG standard and converting it into a signal that conforms to the Internet communication protocol, it is transmitted to the security server 6 together with the client ID code as site information.

【0055】

In order to perform the above operations, the program that operates the fixed terminal device 1B for clients implements a situation change detection means that detects whether or not there is a change in the situation at the site requiring monitoring from the information at the site detected by the monitoring device. A process and a process of realizing a site information transmitting means for transmitting the site information detected by the monitoring device to the security server when the situation change detecting means detects a predetermined change in the situation at the site requiring monitoring are provided. ..

【0056】

In this way, the fixed terminal device 1B for the client first transmits the screen information in which the change in the situation is detected among the screen information detected by each of the cameras installed in the plurality of cameras to the server as priority information, and then transmits the screen information to the server. When a command is given from the security server in response to a command from the client mobile terminal, the image information output by another camera can also be transmitted to the server in response to the command.

【0057】

The fixed terminal device 1B for the client is always connected to the security server 6 via the Internet at least when it is in the security operation mode so that the site information (image information) can be transmitted without delay. Is preferable.

【0058】

The client fixed terminal device 1B also displays a screen as shown in FIG. 3 on its monitor as a user interface. The operation of the fixed terminal device for the client will be described below using this screen.

【0059】

In Fig. 3, 20 ́ shows the outline of the plan view of the client's house, and 21 shows the fence surrounding the residential land. C1 to C4 indicate cameras that image the gardens on the west, north, south, and east sides of the house, respectively.

The help button "?" And the "security mode", "security center", and "security server" buttons are displayed. Further, at the upper part of the screen, buttons of "warning lighting", "emergency warning" and "emergency broadcasting" are displayed. These buttons are clicked when performing a predetermined operation or setting an operation mode, but when each button is clicked, the display of the button becomes brighter or the display color changes. The button is clicked (selected) by the button or the display blinking.

【0061】

Among the buttons displayed on the monitor screen, the "at home" and "going out" buttons are clicked when the operation modes are the home mode and the outing mode, respectively. When the operation mode is home mode and the "security mode" button is not clicked, the automatic security operation is not performed, but the images taken by multiple cameras are displayed on the monitor screen by the operation on the screen. It is possible to let them know and to contact the security center.

【0062】

When the "security mode" button is clicked while the operation mode is in the home mode, the operation mode becomes the security mode (home security mode), and the automatic security operation is performed as in the case of the outing mode described later. Will be.

【0063】

When "going out" is clicked, the going out mode is set, and the operation mode is automatically set to the security mode (going out security mode). In this security mode, when a change in the situation at the site requiring monitoring is detected from the output of the intrusion detector and the image signal obtained from each camera, the image obtained from the image signal of the camera detecting the change in the situation is detected. The information is transmitted from the terminal device 1B to the security server 6 as site information.

【0064】

As will be described later, the security server 6 transmits this image information to the client mobile terminal device 2 to request a determination as to whether or not the change in the situation is due to the occurrence of the change, and the change has occurred. Prompt to return a help request signal when it is determined. When the help request signal is returned from the mobile terminal device for the client, the security server performs necessary processing for the security personnel to start the security activity, such as arranging a patrol car and arranging a helper.

【0065】

Also, when the "Camera display" button is clicked on the monitor screen shown in Fig. 3, the display of the outline line 20 ́ of the house and the display of the outline line 21 of the wall are turned off, and instead, the terminal device 1B is displayed. The images taken by the cameras that are selected sequentially at regular time intervals are displayed on the monitor screen. At this time, in order to clearly indicate the position of the selected camera, the "west", "north", "south", and "east" buttons corresponding to the selected camera are blinked.

【0066】

Furthermore, when the "Camera display" button is clicked and any of the buttons "West", "North", "South", and "East" indicating the position of the camera is clicked, the clicked button is clicked. It is possible to continuously display the image of the camera corresponding to the above on the monitor screen for a certain period of time.

【0067】

Furthermore, when the "Security Center" button is clicked, the screen of the monitor is switched to the screen for exchanging information with the security center, and on that screen, a request for dispatch to the security center, reception of a message from the security center, etc. Can be done.

【0068】

When the "security server" button is clicked, the monitor screen is switched to the screen for exchanging information with the security server 6. On this screen, past security activity records can be read from the server database for viewing, and daily security operation records can be read from the server database for viewing.

【0069】

The "warning lighting", "emergency warning", and "emergency broadcasting" buttons are buttons for selecting whether or not to perform a predetermined alarm operation when a predetermined condition is satisfied, and are buttons for "emergency lighting". When is clicked, when the intrusion detector detects an intruder, the lighting device that illuminates the surroundings of the house is turned on.

【0070】

Also, when the "emergency alarm" button is clicked, the intrusion detector is used when the client determines an abnormality on the mobile terminal device and sends the determination result to the server, or when the operation mode is the home security mode. Detects an intruder and when the terminal device 1B detects a change in the situation from the image signal of the camera, an alarm device such as a bell is operated to generate a warning.

【0071】

Furthermore, when the "emergency broadcast" button is clicked, when the client determines that something has happened to the mobile terminal device in the out-of-home security mode, and intruder is detected in the home security mode, and the terminal device 1B When the client detects the occurrence of an abnormality from the image signal of the camera, a pre-recorded warning broadcast is broadcast through a loudspeaker installed toward the garden.

【0072】

The warning lighting, emergency warning, and emergency broadcasting functions can be optional.

【0073】

The help button "?" Is clicked when you do not understand the operation, and by clicking this button, you can display the explanation of the required operation on the screen.

【0074】

The characters displayed on the monitor screen can be changed as appropriate according to the purpose of security. For example, in Fig. 3, the word "security" is used on the screen of the monitor, but when the purpose of security is crime prevention, for example, the word "security" is used instead of the word "security". It can be used, and the characters such as "security center" and "security company" can be used instead of the characters "security center".

【0075】

The design of the user interface screen displayed on the monitor screen of the fixed terminal device 1B for the client is not limited to the example shown in FIG. 3, and may be appropriately changed according to the operation content or in consideration of usability. it can.

【0076】

For example, an operation for providing a "zoom" button or changing the direction of the lens of the image sensor in order to have a function of zooming up the screen while the screen of each monitoring device is displayed. Buttons can be provided.

【0077】

Although each button may be clicked with a mouse, a touch pen method or a touch panel method may be used for simplification of operation.

【0078】

As described above, when the client fixed terminal device 1B detects that a predetermined change (change in which the presence of an intruder is suspected) has occurred in the situation around the client's house (garden), the situation is changed. The information of the image of the area where the change has occurred is transmitted to the security server 6 as the site information. Changes in the situation at the site can be detected, for example, by observing changes in the average level of the image signal (luminance signal) obtained from the camera over time. In this case, if the screen is divided into a large number of regions and the temporal change of the average level of the luminance signal is observed for each region, the change in the situation can be detected more accurately.

【0079】

Further, as described above, when an intrusion detection detector for detecting whether or not there is an intruder in the place where each camera is photographed is provided, the intrusion detector performs a detection operation for detecting the intrusion of someone. This may be captured as a change in the situation at the site, and an image obtained from a camera showing the location where the intrusion detector is installed may be transmitted to the server as site information.

【0080】

(3) Configuration and operation of security server As shown in FIG. 2, the security server has a registrant database 6a, an image database 6b, a helper database 6c, and a participation status database 6d as a database (DB) for storing various information. By executing a program stored in a hard disk (not shown), S1 to S10 are operated online, and processes P1 to P6 shown in the rectangular frame are performed.

【0081】

The address, ID code, etc. of the contracted client are registered in the registrant database 6a. The image database 6b stores an image (an image including the change in the situation) first transmitted to the security server after the fixed terminal device 1B for the client detects the change in the situation. A part of the image information stored in the image database 6b is updated every time the fixed terminal device for the client detects a change in the situation at the site and sends a new image to the security server. In addition, the helper database 6c contains the address information of helper personnel (people who have consented to cooperate as helpers) according to the recruitment conducted by the security center, information on the time zone for cooperation as a helper (cooperation time information), and the content of cooperation (cooperation time information). Security, nursing, etc.) are registered. Furthermore, in the participation status database 6d, the participation status of each helper personnel, such as the number of requests for cooperation to each helper personnel registered in the helper database 6c, the number of past cooperations of each helper personnel, the actual working hours of each helper personnel, etc. Is recorded.

【0082】

The security server 6 receives S1 such as an ID code and an image signal transmitted from the fixed terminal device of the client, and performs client terminal image reception processing P1. In this client terminal image reception process, first, the ID code of the client sent from the fixed terminal device 1B for the client is referred to the ID code registered in the registrant database 6a to determine whether or not the client is a contractor. After confirming and completing the confirmation, update the information in the image database 6b S2, and store the new image information transmitted from the fixed terminal device for the client together with the current date and time in the corresponding storage of the image database 6b. Write in place. At this time, the image data recorded in the image database before a certain period is deleted.

Further, the server 6 performs the client call request S3 and performs the client mobile call processing P2 that calls the client terminal device 2. In this process P2, a process of transmitting the number of the client mobile terminal device 2 to the exchange of the mobile communication network and calling the corresponding mobile terminal device 2 is performed. When the client puts the mobile terminal device 2 in a call state and responds to the access from the security server, the initial screen with various menus is displayed on the screen of the client mobile terminal device 2, and a predetermined screen is displayed on the initial screen. By letting the client select the menu, the client is made to request the image transmission. The security server 6 performs transmission S4 of the latest received image stored in the image database 6b when an image transmission request is received from the client.

【0084】

The security server transmits the latest image received from the fixed terminal device for the client to the mobile terminal device 2 of the client in this way, and by showing the image to the client, the client himself / herself is at home (monitoring site required). To determine whether or not an abnormality has occurred in, and prompt the reply of the help request signal.

【0085】

A means for requesting a help request reply for a client, which transmits the site information transmitted from the fixed terminal device for the client to the mobile terminal device for the client and prompts the client to reply to the help request signal in the process of performing the client mobile call processing P2. To configure.

【0086】

The client confirms the status of the monitoring site at home sent from the security server on the screen of the mobile terminal device 2, and requests help when it is determined that something unusual such as the intrusion of a suspicious person has occurred at home. The signal is returned to the security server 6. When it is determined that no abnormality has occurred at home, the client mobile terminal device transmits a stop signal instructing the security server to stop the help request.

【0087】

An example of the user interface screen displayed on the client mobile terminal device 2 by the security server 6 is shown in FIGS. 4 (A) to 4 (C). Figure 4 (A) shows the initial screen of the security menu that is displayed first when the client puts the mobile terminal device into a call state in response to a call from the security server. This initial screen shows "1 client image 1". , "2 Client Image 2", "3 Security Server", "4 Help", and "5 Finish" menus are displayed.

【0088】

When the client selects "Client Image 1" on this initial screen, an image transmission request is sent to the security server. When this transmission request is made, the security server 6 transmits the latest image transmitted from the client's home and stored in the image database 6b to the mobile terminal device 2 as shown in FIG. 4 (B). Display on that screen. When the client who sees this screen determines that something is wrong with his / her home, he / she selects "Send" displayed at the lower left of the screen of the mobile terminal device, thereby sending a help request signal to the security server 6. Let me. If the client cannot determine whether or not an abnormality has occurred from the screen displayed first, return to the initial screen by selecting "Menu" at the bottom right of the screen, and then select "2 Client image 2". ..

【0089】

At this time, the security server gives a screen switching command to the fixed terminal device 1B for the client, sequentially switches and transmits the current images (Fig. 4C) taken by the plurality of cameras at the client's home, and those images are transmitted. Is transmitted to the mobile terminal device 2, and images of the site are sequentially displayed on the monitor screen of the mobile terminal device 2 in near real time. As a result, when it is determined that an incident has occurred at home, the client is made to select "Send" to send a help request signal to the security server, and when it is determined that an incident has not occurred, "Send" is selected. Select "Cancel" to send a stop signal to the security server.

【0090】

The security server also displays a menu screen (not shown) for communicating with the security server when the client selects "3 security server" on the initial screen of FIG. 4 (A). By accessing the security server on this menu screen, the client can view the communication records stored in the management information database (not shown) of the security server, and the client can carry it from the security server without noticing it. Notify the client of the history of security activities such as whether or not the terminal device 2 has been accessed and whether or not an accident has occurred at the client's home and the security activities have been performed without noticing it. Also, by letting the client select "4 Help" on the initial screen, the operation method is displayed, and by selecting "5 End", the operation is terminated.

【0091】

The security server 6 performs the client mobile request reception process P3 when there is a signal transmission S5 (see FIG. 2) from the client mobile terminal device 2. In this process P3, the screen of the mobile terminal device 2 is switched, a command signal is transmitted to the fixed terminal device 1B for the client, or a helper call request is requested according to the content of the signal transmitted from the mobile terminal device 2 for the client. Perform various processes such as.

【0092】

When the client selects "2 client screen 2" on the screen of the mobile terminal device, a screen switching command is given to the fixed terminal device 1B for the client, and the images captured by the plurality of cameras are sequentially switched and transmitted. It is instructed to do so, and the transmitted image is transmitted to the mobile terminal device 2 for the client.

【0093】

When the help request signal is returned from the client mobile terminal device 2, the security server makes a helper call request request S6 to perform the helper selection process P4. In this helper selection process, a plurality of helper candidates are selected from the helper personnel registered in the helper database 6b in advance under predetermined conditions, and the helper's past recorded in the participation status database 6d is selected. Refer to the activity record and select at least one helper who seems to be the best. The conditions for selecting helper candidates are, for example, that they live within a certain distance from the client's home, that the time zone when the incident occurred coincides with the time zone when the consent of the helper staff is obtained, and that security is provided. The content of the activity matches the content agreed by the helper personnel.

【0094】

Figure 5 shows an example of the helper selection algorithm. When following the algorithm shown in Fig. 5, multiple helper personnel who meet the conditions such as living near the area where the incident occurred in step 1 and the time zone for cooperation are met. Is searched from the helper database 6c as a helper candidate. Next, the past cooperation status of the helper candidates searched in step 2 is read from the participation status data 6d, and in step 3, helper candidates are extracted one by one in ascending order of the number of past cooperation requests. Next, it is determined whether or not the number of past requests for the helper candidate extracted in step 4 is 0, and if the number of requests is 0, the process proceeds to step 5 and this candidate is determined as a helper. ..

【0095】

In this way, the candidate whose number of requests is 0 is preferentially determined as a helper until when the number of cooperation of the newly registered helper candidate (the number of requests is zero, so naturally the number of cooperation is also zero). This is to prevent it from being held in the state of zero.

【0096】

When it is determined that the number of requests to the candidate extracted in step 4 is not 0, it is determined in step 6 whether or not the past cooperation degree of the candidate is equal to or higher than the judgment value Kn, and the cooperation degree is the judgment value. If it is Kn or higher, the process proceeds to step 5 and the candidate is determined as a helper. When it is determined in step 6 that the degree of cooperation is less than the determination value Kn, the process proceeds to step 7, and among the candidates searched in step 1, whether or not there are any candidates who have not yet determined the conditions. If there are any remaining candidates, proceed to step 3 to extract one candidate with the next lowest number of requests, move to step 4, and repeat the same process as above. If it is determined that there are no other candidates remaining in step 7, the process proceeds to step 8, subtracting 1 from the value of n to set the determination value to Kn-1, and repeating step 3 and subsequent steps. When these processes are repeated until n becomes 0, the judgment value Kn finally becomes K0 (= 0), so if only a helper candidate can be identified, the helper will always decide.

【0097】

Through the process of FIG. 5, among the helper candidates registered when the help request signal is returned from the mobile terminal device for the client, the helper is selected from the helper candidates who have a place near the client's place of residence. A helper selection means for selecting at least one person is constructed.

【0098】

After the helper is determined as described above, the dispatch request request S7 (see Fig. 2) to the determined helper is performed, and the helper / security center call process P5 is performed. In this call processing, a help command is transmitted S8 requesting the client to be dispatched to the home of the helper fixed terminal device 5A and the helper mobile terminal device 5B having a GPS function, and at the same time, the security center. This is also done for the terminal device 3 and the patrol car 4. This help directive is a directive that includes geographic information about the client's home.

【0099】

In the security server shown in the figure, through these processes, a help command means for sending a help command including a dispatch command to the client's whereabouts and geographic information of the client's whereabouts to the helper terminal device, and a dispatch request to the patrol vehicle are sent. The patrol vehicle dispatch requesting means to be performed is configured, and when a help request signal is returned from the mobile terminal device for the client by these help command means, the patrol vehicle dispatch requesting means, and the helper selection means, a security officer (helper) And the security activity request processing means that performs the processing to request the start of the security activity to the occupants of the patrol car).

【0100】

When the helper puts the mobile terminal device 5B into a call state, the security server 6 displays an initial screen (menu screen) as shown in FIG. 6A on the display screen of the mobile terminal device 5B. On the initial screen, for example, the menus of "1 client map", "2 security server", "3 patrol car", "4 helper position", "5 help" and "6 end" are displayed, and the helper is made to "1 client". By selecting "Map", the wide area map screen as shown in Fig. 6 (B) is displayed, and the current position H1 of the mobile terminal device and the client's home H2 are displayed on the wide area map displayed on this screen. By instructing the helper to the destination, the security server also causes the helper to select the "details" displayed at the lower left of the wide area map screen of Fig. 6 (B), as shown in Fig. 6 (C). To display a detailed map near the client's home.

【0101】

The security server also displays a screen for communicating with the security server on the screen of the helper mobile terminal device by selecting "2 security server" on the screen of FIG. 6 (A). Let them select this "2 security server" when the helper arrives at the site, and let the helper report that they have arrived at the site. Similarly, by selecting "3 patrol car", it is possible to communicate with the patrol car. Also, by selecting "4 helper position", the current position of the helper is displayed. In the menu of FIG. 6 (A), "5 help" is to be selected when the operation is not understood, and "6 end" is to be selected when the operation is finished.

【0102】

If the determined helper does not consent, or if the helper's portable terminal device does not respond, return to step 1 and exclude the helpers who consented or did not respond and perform the helper selection process in Fig. 5. Start over.

【0103】

After the security server receives the image from the fixed terminal device 1B for the client, the mobile terminal device for the client responds when the client mobile call processing P2 is performed to send the image to the mobile terminal device for the client. If not, the image transmitted from the fixed terminal device for the client is sent to the terminal device for the security center, and the person in charge of the security center is made to judge the presence or absence of an abnormality on behalf of the client and a help request signal is returned. Perform the process to make it. Therefore, when the client mobile terminal device does not respond to the program executed by the security server, the image (site information) transmitted from the client fixed terminal device is transmitted to the security center terminal device to provide the security. Provide a process to realize a help request reply request means for the security center that prompts the person in charge of the center to reply to the help request signal.

【0104】

Similar to the case where the help request signal is returned from the client mobile terminal device, when the help request signal is returned from the security center, the process of selecting the helper is performed, and the helper terminal possessed by the selected helper is performed. A help command including a dispatch command to the client's whereabouts and geographic information of the client's whereabouts is transmitted to the device 5.

【0105】

As shown in the illustrated example, if the fixed terminal device 5A is provided in addition to the mobile terminal device 5B as the helper terminal device 5, the security server may send a message or news to the helper personnel. Therefore, helpers can be managed appropriately. In addition, since the fixed terminal device for helpers can be used to notify each helper member of the activity status of other helper personnel, it is possible to raise the awareness of the helper personnel regarding the security activities.

【0106】

When a help command is given to the helper mobile terminal device 5B as in the above example, the helper fixed terminal device 5A can be omitted. In some cases, the helper fixed terminal device may be given a help command so that the helper mobile terminal device can be used only for communication with the helper, or the helper mobile terminal device can be omitted.

【0107】

In the above explanation, help commands are given to the helper and the security center at the same time, but when the client sends a help request command to the security server, the security center is first requested to dispatch a patrol person, and then the helper is sent. The selection process may be performed.

【0108】

(4) Configuration of terminal device for security center As shown in FIG. 7, the monitor of the security center terminal device 3 should be capable of displaying a screen similar to the screen displayed on the monitor of the client fixed terminal device. The display of the house and the display of the camera in the center of the screen of Fig. 7 are the same as those displayed on the monitor of the fixed terminal device 1B for the client, and are "camera display", "west", "north", "south", and "east". The function of the "" button is the same as that displayed on the monitor of the fixed terminal device for clients.

【0109】

On the monitor screen of the terminal device of the security center, the client's name and client number are displayed on the upper left, and the "map display", "security server" and "patrol car" buttons are displayed on the right. On the left side of the screen, buttons for "client PC", "client mobile phone", "help PC", and "help mobile phone" are displayed.

【0110】

If you click "Map display" on this screen, you can display the map of the client's home, and if you click "Security server", you can display the information registered in the security server. ing. You can also contact the patrol car by clicking "Patrol car".

【0111】

Also, by clicking "Client PC", it is connected to the fixed terminal device 1B for the client, and in this state, the functions of the "Camera display", "West", "North", "South", and "East" buttons are displayed. You can use it to monitor the image taken by the client's home camera. However, this function works only when the client's home terminal device is in security mode.

【0112】

Also, by clicking "Client mobile", you can access the client's mobile terminal device and talk to the client, and by clicking "Help mobile", you can use the helper's mobile terminal device. You can make a call. Also, by clicking "Help PC", it is possible to access the helper fixed terminal device 5A and send a necessary message to the terminal device 5A.

【0113】

(5) Overall operation of the system An example of a flowchart showing the flow of processing in the above security system is shown in FIGS. 8 and 9. A series of processes when following this flowchart is as follows. In step 1, the client's home camera detects the suspicious person, and the image is given to the client fixed terminal device 1B. When the fixed terminal device for the client determines from this image that the situation in which a suspicious person is suspected to have changed has occurred, step 2 is performed to transmit the image to the security server. The security server records the data of this image in the database in step 3, and then transmits the image data to the client mobile terminal device 2 in step 4. If this transmission is successful in step 5, the client is made to check the image in step 6 to determine whether or not a suspicious person has invaded. As a result, when the client determines in step 7 that a suspicious person has invaded, the process proceeds to step 8 to issue a dispatch command to the patrol vehicle in charge of the area including the site and rush to the site (step 9 in FIG. 9). ..

【0114】

If the transmission to the client mobile terminal device 2 is not successful in step 5, the image data recorded in the database is transmitted to the security center in step 10, and the person in charge of the security center is invaded by a suspicious person. Whether or not to determine (step 11) is performed. As a result, when the person in charge determines that the intrusion is a suspicious person, the person in charge of the security center sends a help request signal to the security server on behalf of the client in step 12. In response to this, the security server issues a dispatch command to the patrol vehicle (step 8).

【0115】

After the security server issues a dispatch command to the patrol vehicle in step 8, the process proceeds to step 13 in FIG. 9, the helper is selected, and the selected helper is instructed to rush to the site as soon as possible. When the helper signs an understanding of rushing to the scene in step 14, the security server records helper information in the cooperation status database indicating that the helper cooperated with the request (step 15). Then, in step 16, the helper is informed of the map of the client's home (site), and the map information is transmitted to the helper's mobile terminal device to rush the helper to the site (step 17 in FIG. 9).

【0116】

When the helper and patrol vehicle arrive at the site, have the helper and patrol vehicle check the site situation and let both parties share the site situation (steps 18 and 19), and the site situation and the result of processing are reported to the patrol vehicle and the patrol vehicle. Have the helper report to the security server (step 20). Next, the security server records the final status of the event that occurred in step 21 in a management information database (not shown) provided in the security server, and in step 22, the final status of the event that occurred is recorded in the mobile terminal device for the client and the terminal for the security center. Contact the device. The security server uses the GPS function of the helper mobile terminal device to check whether the helper has actually arrived at the site and registers the result.

【0117】

When the helper arrives at the site before the patrol car, the helper is first asked to confirm the situation at the site, and the suspicious person is notified of the existence of the helper by means such as pressing the intercom and sounding the chime. By having the helper take such an action, in most cases, it is possible to abandon the suspicious person from committing the crime, and thus it is possible to prevent actual harm such as theft. If the suspicious person does not leave even after notifying the suspicious person of the existence of the helper, let the suspicious person monitor the situation of the suspicious person, wait for the patrol car to arrive, and let the patrol car occupant handle the suspicious person. .. If a suspicious person has already committed a crime, contact the security center immediately, and in some cases, contact the police. Since helpers are only collaborators in crime prevention, it is necessary to avoid taking dangerous actions such as direct confrontation between helpers and suspicious persons.

【0118】

In step 7 of FIG. 8, when the client determines that this event is not an intrusion of a suspicious person and does not return a help request signal, and in step 11, the person in charge of the security center is not an intrusion of a suspicious person. When it is determined that the help request signal is not returned, the process proceeds to step 21 of FIG. 9, and the security server records the final status of the occurrence event in the management information database, and then the final status (processing for this event). Contact the mobile terminal device for the client and the terminal device for the security center.

【0119】

(6) Processing performed by the management terminal device In the example shown in FIG. 2, the management terminal device 13 installed at the security center 30 or the installation location of the security server 6 is connected to the security server 6 via LAN, and the WWW server 7 and the Internet 8 are connected. It is connected to the fixed terminal device 1B for the client, the terminal device 3 for the security center, and the fixed terminal device 5A for the helper through the above, and this management terminal device performs the processes A to E indicated by the broken lines offline. The contents of these processes are as described in (a) to (e) below.

【0120】

(a) Client registration process A When the client makes an application to the security center (security company in the above example), the client information input by the operator through the keyboard or the like is registered in the database 6a in the security server 6.

【0121】

(b) Helper participation status check process B When there is an inquiry about the participation status of the helper through the keyboard etc., access the participation status database of the security server and check the past participation status of the helper (number of dispatch requests, number of cooperation, degree of cooperation, etc.).

【0122】

(c) Collaborator registration process C Register the helper personnel who applied for the recruitment in the helper database 6c of the security server. This registration is performed by the input operation of the operator.

【0123】

(d) Image data storage process D When requested by the client or the security center, the image recorded in the image database 6b of the security server (the image transmitted from the fixed terminal device for the client) is read and recorded in FD, MO, CD-R, etc. Record on a medium. This record is used as evidence when a proceeding is filed regarding an event (incident) that occurred at the client's home.

【0124】

(e) Support processing E Notify when there is an inquiry about the record of one-day security activity or the record of past activity from the fixed terminal device for the client. In addition, the security news issued by the security center is transmitted to the fixed terminal device for clients and the fixed terminal device for helpers.

【0125】

In addition to the above processing, the management terminal device 13 performs various necessary processing offline, such as calculation of a fee to be paid to the helper and charging processing to the client.

【0126】

Depending on the contract, the client can be charged by a flat-rate method that collects a fixed amount every month, such as the number of times image data is sent from the fixed terminal device for the client to the security server and the dispatch of a helper. It is also possible to use an actual method that is calculated based on the number of occurrences of. The fee paid to the helper is calculated according to the activity status such as the number of times the helper is dispatched and the actual working hours.

【0127】

(7) Other embodiments of the present invention In the above embodiment, the change in the situation at the site is detected by the fixed terminal device for the client, but when the fixed terminal device for the client and the server are always connected, the change in the situation at the site is detected. It may be detected on the server side.

【0128】

In this case, the security server is provided with a status change detecting means for detecting the presence or absence of a change in the status of the monitoring-required site from the site information transmitted from the fixed terminal device for the client to the security server. In addition, the help request reply request means provided in the security server receives the site information transmitted from the fixed terminal device for the client when the situation change detecting means detects that a predetermined change has occurred in the situation at the site requiring monitoring. It is configured to be sent to the mobile terminal device for the client to prompt the client to reply with the help request signal.

【0129】

In the above description, the case where the present invention is applied to a security system aimed at preventing a suspicious person from invading the client's home is taken as an example, but the purpose is to protect the safety of the sick and the elderly requiring long-term care. The present invention can also be applied to a security system or the like that monitors the condition of a person requiring long-term care and dispatches a helper when an abnormality occurs.

【0130】

In the case of a security system for the purpose of long-term care, it is necessary for the helper to enter the inside of the house after arriving at the site, and the helper needs to have knowledge of long-term care. Select a qualified person such as a woman or a caregiver, and leave the key of the client's whereabouts to the helper in advance. In this way, when it is necessary to entrust the key of the client's whereabouts to the helper, one or more helpers are determined in advance for each client, and a trust relationship is established between the client and the helper. It is necessary to keep it. In this way, when the helper to be dispatched to each client is decided in advance, the helper is selected as shown in FIG. 5 when the help request signal is returned from the client's mobile terminal device to the security server. There is no need to perform any processing, and a predetermined helper may be selected for the client.

【0131】

In addition, when a fixed helper terminal device is installed in a relatively large hospital in the area, the key of the client's whereabouts is stored in the hospital, and a help request signal is returned from the client's mobile terminal device to the security server. , A help command may be sent from the security server to a fixed terminal device for helpers in a hospital, and a doctor or a nurse may be dispatched from the hospital as a helper.

【0132】

Furthermore, fixed terminal devices for helpers are installed in each of multiple private hospitals scattered in the area, and the terminal devices of each hospital and the security server are connected via a communication network, and the client's mobile terminal device is used for security. When the help request signal is returned to the server, the help command is sent to the helper fixed terminal device of the nearby hospital selected by the client, and the doctor or nurse of the hospital is rushed to the client's whereabouts as a helper. You may do so. In this case, the key to each client's whereabouts should be deposited at a nearby hospital selected by the client.

【0133】

As described above, when a fixed helper terminal device is installed in a hospital, the helper terminal device has a function to monitor the status of the client's location requiring monitoring (hospital room) and the condition of the sick person (pulse, blood pressure, etc.). It is preferable to have it in. Further, it is preferable that the information on the floor plan (location of the hospital room) of the client's whereabouts can be displayed on the screen of the fixed terminal device for helpers.

【0134】

In the above embodiment, the television camera is used as the monitoring device for monitoring the site, but the site information may be acquired by using an image sensor other than the television camera. It is preferable to use an image sensor in order to accurately grasp the information on the site, but in some cases, the sound generated at the site may be used as the site information to determine the presence or absence of an abnormality. In addition, when detecting an abnormality such as a sick person or an old man, when it is detected that the sick person or the old man does not move for a certain period of time, or whether or not the sick person or the old man responds to a voice call is detected. This makes it possible to detect the presence or absence of an abnormality. Further, a monitor device for monitoring the pulse, blood pressure, respiratory sound, etc. of the sick person or the elderly person may be provided, and information on the state of the sick person or the elderly person may be obtained from the output of the monitor device.

【0135】

For the purpose of caring for the sick or the elderly, when calling the client's mobile terminal device from the security server and asking the client to judge the situation of the care recipient, the care recipient is using the client's mobile terminal device. It is preferable to make a voice call to the client so that the reaction can be confirmed. For that purpose, for example, a microphone for detecting the voice of the care recipient is provided at the site (hospital room, etc.) and a loudspeaker is provided, and the voice of the client is transmitted from the mobile terminal device for the client to the loudspeaker at the site through the security server. , The voice of the person being cared for can be transmitted to the mobile terminal device for the client through the security server.

【0136】

In the above embodiment, it is assumed that the mobile terminal device provided to the helper has the GPS function and the image receiving function, but a normal mobile phone having no GPS function and the image receiving function is used as the helper mobile terminal device. You may use it. When a normal mobile phone having only a call function is used as a helper mobile terminal device, the security server gives the helper a dispatch request and geographical information of the site by voice.

【0137】

[Effect of the invention]

As described above, according to the present invention, when a change in the situation occurs at the client's whereabouts, the information is transmitted to the client's mobile terminal device to cause the client itself to determine whether or not an abnormality has occurred. Since the security activities are started based on the judgment result, it is possible to prevent unnecessary security activities from being carried out based on the misunderstanding of the situation at the site.

【0138】

Further, in the present invention, when an abnormality occurs in the client's whereabouts, the patrol vehicle managed by the security center is requested to be dispatched, and at the same time, the helper who has a residence near the client is requested to be dispatched. When a car is delayed in arriving at the site due to traffic congestion or the like, there is an advantage that the helper can arrive at the site first to carry out security activities.
