As shown in the floor plan of the system house in FIG. 1, in the LDK, the air conditioner 31 has a wireless sensor 21 (not shown) which is a movement destination detection unit capable of detecting whether or not a user or the like is in the room. It is connected via the communication unit. Similarly, in the corridor, the motion sensor 22 is connected to the air conditioner 32 via a wireless communication unit (not shown). Further, in the living room, the motion sensor 23 is connected to the air conditioner 33 via a wireless communication unit (not shown). Further, in the toilet, the motion sensor 24 is connected to the air conditioner 34 via a wireless communication unit (not shown). Further, in the dressing room, the motion sensor 25 is connected to the air conditioner 35 via a wireless communication unit (not shown). Further, in the bath, the motion sensor 26 is connected to the air conditioner 36 via a wireless communication unit (not shown).

The air conditioning control device 10 is a portable air conditioner remote control device (remote controller) with a built-in battery and a built-in sphygmomanometer. Although the air conditioning control device 10 is located in the LDK in FIG. 1, the air conditioning control device 10 can control the air conditioning of the air conditioners 32 to 36 in other rooms in addition to the air conditioner 31 in the LDK.

FIG. 2 is a diagram showing a configuration example of the air conditioning control device of the present embodiment. The air conditioning control device 10 communicates with the vital sign measurement unit 11, the time management unit 12, the position measurement unit 13, the personal information database (DB) 14, the display notification setting unit 15, and the movement location estimation unit 16. It includes a control unit 17.

The vital sign measuring unit 11 measures the vital signs (biological information) of the user (measured person) carrying the air conditioning control device 10. Specifically, in the vital sign measuring unit 11, the blood pressure measuring unit 111 measures the user's blood pressure, the pulse measuring unit 112 measures the user's pulse, the body temperature measuring unit 113 measures the user's body temperature, and the consciousness level is measured. The user's awareness level is measured in part 114. In the vital sign measuring unit 11, each unit simultaneously measures the required biological information.

The vital sign measurement unit 11 is connected to the time management unit 12 that ticks the current time and the position measurement unit 13 that measures the current position in the house, and the measurement results measured by each unit in the vital sign measurement unit 11 ( Vital value) is stored in the personal information DB 14 in association with the time information and the location information. The information stored in the personal information DB 14 can be displayed by the display notification setting unit 15. When the vital sign measurement unit 11 stores the measurement result (vital value) in the personal information DB 14, it can be associated with only one of the time information and the position information.

The movement location estimation unit 16 estimates the movement destination of the user carrying the air conditioning control device 10 based on the information acquired from the position measurement unit 13, the personal information DB 14, and the communication control unit 17. Further, the moving place estimation unit 16 determines the conditions such as the temperature to be set at the estimated moving destination by the set temperature determining unit 161.

The communication control unit 17 communicates with the wireless communication units 41 to 43 of other rooms, etc. via the antenna 171 to acquire information on the environmental conditions such as temperature and humidity of other rooms, and determines the set temperature. A command for controlling the air conditioners 31 to 33 of another room or the like is transmitted at the temperature determined by the unit 161.

Next, the operation of controlling the air conditioner of another room or the like in the air conditioning control device 10 will be described.

Here, as an example, in the floor plan of the system house shown in FIG. 1, a case where a user in the LDK moves to the living room will be described for the LDK, the corridor, and the living room. In the LDK, the motion sensor 21 is connected to the air conditioner 31 via a wireless communication unit 41 provided with an antenna 411. Further, in the corridor, the motion sensor 22 is connected to the air conditioner 32 via a wireless communication unit 42 provided with an antenna 421. Further, in the living room, the motion sensor 23 is connected to the air conditioner 33 via the wireless communication unit 43 provided with the antenna 431. The air conditioner 31 is wirelessly connected to the wireless communication unit 41 by a connection line, the air conditioner 32 is wirelessly connected to the wireless communication unit 42, and the air conditioner 33 is wirelessly connected to the wireless communication unit 43. This is an example and is wireless to the air conditioner 31. The communication unit 41 may be wirelessly connected. It should be noted that the distance between the wireless communication units 41 to 43 and the motion sensors 21 to 23 to be connected is sufficiently short, and the communication time can be ignored.

First, the user who is the person to be measured wears the air conditioning control device 10 on his / her arm or the like at all times in the form of a cuff of a blood pressure monitor. Then, in the air conditioning control device 10, the vital sign measuring unit 11 automatically measures biological information such as blood pressure of the person to be measured. The measurement timing is appropriately measured according to the user's situation based on the time of the time management unit 12 or the position information of the position measurement unit 13. The trigger for starting the measurement in the blood pressure measuring unit 111, the pulse measuring unit 112, and the body temperature measuring unit 113 is the timing when the consciousness level measuring unit 114 confirms the consciousness of the user. Regarding the measurement method of each part, the blood pressure measuring unit 111 measures according to the existing blood pressure measuring method, and the pulse measuring unit 112 and the body temperature measuring unit 113 also measure the pulse and the body temperature based on the existing method. For example, when measuring blood pressure with the blood pressure measuring unit 111, it is not accurate unless the sphygmomanometer part is close to the position of the heart, so a cuff is attached near the height of the heart of the upper arm or wrapped around the wrist. In order to improve the accuracy of measurement, the relationship between arm height and blood pressure is input in advance and stored in the personal information DB14.

The timing of measurement by the vital sign measurement unit 11 may be performed periodically. By saving the record measured regularly in the personal information DB14, the change in the physical condition of the user during the day can be recorded as a record, which can be used as information when detecting the abnormal state of the user. it can.

The vital sign measurement unit 11 stores the vital value information measured by each unit in the personal information DB 14 in association with the time information from the time management unit 12 and the position information from the position measurement unit 13. The information from the position measurement unit 13 includes the distance from the motion sensors 21 to 23 (or the wireless communication unit 41 to 43) in the house, the inclination information of the air conditioning control device 10, and the acceleration (x, y) by the built-in acceleration sensor. , Z direction) information etc. Further, in the position measuring unit 13, for example, the communication control unit 17 sends a wireless radio wave to the wireless communication units 41 to 43 connected to the motion sensors 21 to 23, and the current position is specified based on the difference in response time. However, the method of specifying the current position is not limited to this.

The movement location estimation unit 16 obtains the moving direction of the user wearing the air conditioning control device 10 based on the current position information and the vector information of the acceleration sensor, which are the information from the position measurement unit 13. The candidate room that the user is going to move is estimated by referring to the floor plan information of the controlled object stored in the personal information DB14. In the air conditioning control device 10, the past behavior pattern may be stored in the personal information DB 14 as the behavior pattern of the user wearing the air conditioning control device 10. For example, information such as when to wake up, move to a room, when to take a bath, and when to go to bed is saved as a past behavior pattern. When estimating the movement destination of the user, the movement location estimation unit 16 can further estimate based on the probability of the location in the same time zone by referring to the past behavior pattern stored in the personal information DB 14. The estimation accuracy can be improved.

The movement location estimation unit 16 controls communication of the current LDK, the estimated destination (here, the living room in FIG. 1), and the temperature and humidity information in the room on the route (here, the corridor in FIG. 1). Obtained from wireless communication units 41 to 43 via unit 17. The wireless communication units 41 to 43 of each room may be obtained from a thermo-hygrometer or the like that has indoor temperature / humidity information by itself, or from the connected air conditioners 31 to 33 and motion sensors 21 to 23. It may be obtained, or other methods may be used.

In the moving place estimation unit 16, the set temperature determination unit 161 obtains the measured value of the user's biological information and the room temperature information according to the vital information (maximum blood pressure of the systolic blood pressure value determined for each age) from the personal information DB14. Then, based on the temperature information of each room, etc. acquired from the communication control unit 17, the set temperatures of the air conditioners 32 and 33 on the estimated destination and route are determined with respect to the current temperature state of the LDK, and the air conditioner 32,33 are instructed to operate at the set temperature via the communication control unit 17 and the wireless communication units 42,43. This allows the user to operate the destination air conditioner 33 and the route air conditioner 32 before moving to the destination room and the corridor on the route, eliminating the temperature difference from the current LDK temperature. , It is possible to provide a comfortable environment for the user.

Here, since the user moves to the living room via the corridor, the set temperature determination unit 161 also targets the air conditioner 32 in the corridor, which is the route, but the route when the user moves to the adjacent room. You don't have to think about.

As described above, since the air conditioning control device 10 performs control according to the user who carries (wraps) the own device, the air conditioning control device 10 can identify each individual, and the user can identify each individual in advance. Personal information such as age will be entered.

The set temperature determination unit 161 simply determines the set temperature of the air conditioners 32 and 33 on the estimated destination and route by using the current temperature information of the LDK and the measured value of the user's biological information. It is also possible. As a result, the air conditioning control device 10 does not need to input personal information in advance, and can cope with a case where a plurality of users frequently take turns using it.

In addition, the set temperature determination unit 161 also acquires the estimated temperature information of the moving destination (living room) and the room on the route (corridor), and determines the set temperature of the air conditioners 32 and 33 on the estimated moving destination and the route. However, it is not limited to this, and at least if the temperature information of the LDK in which the user is currently located is available, the set temperature of the air conditioners 32, 33 on the estimated destination and route can be determined. It is possible to control to eliminate the temperature difference from the current LDK temperature.

In the air conditioning control device 10, the set temperature determination unit 161 of the movement location estimation unit 16 displays the temperature information set / commanded to the air conditioners of other rooms or the like on the display notification setting unit 15. As a result, the user can recognize the commanded content via the display notification setting unit 15, so that if the user does not move, the command can be canceled here.

Further, the display notification setting unit 15 may display the temperature information acquired by the movement location estimation unit 16 from the movement destination and the wireless communication unit on the route via the communication control unit 17. As a result, the user can wait until the temperature of the destination is sufficiently optimized. Here, by recording the information of the destination in the personal information DB 14 with time, it is possible to accumulate data on the behavior of daily life and utilize it as information on which room is likely to be in each time zone.

Regarding the air conditioning control device 10, the temperature information of the room or the like to which the user intends to move is acquired via the movement location estimation unit 16 and the communication control unit 17 and displayed on the display notification setting unit 15. It is also possible to remotely control the operation of the air conditioner at the destination by the user's own operation.

With regard to the air conditioning system provided with such an air conditioning control device 10, when a person with hypertension lives at home or in a welfare facility for the elderly, the room temperature is controlled based on the individual's physical condition. It is possible to control the air conditioning to the optimum ambient temperature based on personal biometric information so that the blood pressure does not rise sharply due to the temperature difference of the room temperature and complications do not occur. In addition, for example, when there are a plurality of subjects (users) in a care welfare facility, the information recorded in the personal information DB 14 of each air conditioning control device 10 worn by each user is used for care welfare. It may be transmitted to the management device handled by the facility manager. As a result, it can be expected to be used in medical fields such as tracking destinations and automatically collecting vital signs, and is also useful for preventing medical accidents caused by not being aware of abnormal vital signs.

In the present embodiment, one wireless communication unit, one air conditioner, and one motion sensor are installed in each room in the house, but the installation pattern is not limited to this. For example, when the room is large or the corridor is long, a plurality of motion sensors and wireless communication units may be installed in the room and the corridor. As a result, in the air conditioning control device 10, the position measuring unit 13 identifies the user's position based on the user's detection information by the motion sensor, and the moving place estimation unit 16 measures the user's position in the position measuring unit 13. Every time the position is changed, that is, the movement destination of the user can be estimated by using the detection order of the user by the motion sensor.

In the air conditioning control device 10, if it is not possible to estimate the moving destination to one place, it is possible to perform air conditioning control for a plurality of rooms and the like. As described above, by installing a plurality of motion sensors and wireless communication units in a corridor or the like, the air conditioning control device 10 performs air conditioning control by narrowing down the destination while the user is moving. It is also possible to gradually reduce the number of rooms and the like. In the air conditioning control device 10, the positions of a plurality of motion sensors (and wireless communication units) arranged in the house are stored in the personal information DB 14 as sensor position information, and the movement location estimation unit 16 is an individual. Using the sensor position information stored in the information DB 14, the user's movement destination may be estimated from the user's detection order by the motion sensor by directly using the user's detection information by the motion sensor.

As described above, according to the present embodiment, the air conditioning control device 10 which is an air conditioner remote control device with a built-in blood pressure monitor and the wireless communication unit of each room capable of transmitting room temperature information to the air conditioning control device 10. In an air conditioning system in which 41 to 43 are networked and an air conditioner can be remotely controlled via wireless communication units 41 to 43, the air conditioning control device 10 predicts the user's destination and is on the destination and route. It was decided to control the air conditioner in the room or the like to control the temperature to the optimum temperature for the user moving in the house according to the user's condition. As a result, the room temperature of the destination can be controlled according to the blood pressure value of the user, the temperature difference from the destination can be eliminated so that the ambient temperature does not change suddenly, and a situation that impairs health such as a sudden rise in blood pressure can be prevented. Can be done. In addition, it is not necessary to operate the air conditioner in a room other than the destination, a comfortable environment can be provided to the user at low cost, and it is not necessary to control the air conditioning of the entire house, so that an energy saving effect can be obtained.

Further, by providing the air conditioning control device 10 with a behavior prediction type schedule function that can record the user's behavior pattern and preheat the destination in advance, the temperature difference can be eliminated more reliably. Furthermore, an energy saving effect can be obtained. For example, the movement location estimation unit 16 refers to the user's movement destination information recorded in the personal information DB 14, and if the user has a certain behavior pattern, the user before detecting the user's movement. The destination of the movement can be estimated. The set temperature determination unit 161 receives a notification to that effect when the movement location estimation unit 16 estimates the user's movement destination, and can determine the set temperature of the movement destination.

In addition, in FIG. 2, the configuration installed in each room or the like has three configurations of a motion sensor, a wireless communication unit, and an air conditioner, but the configuration is not limited to this. For example, if the motion sensor has a wireless communication function, only the motion sensor with the wireless communication function and the air conditioner may be configured, and if the air conditioner has the wireless communication function, the motion sensor may be configured. And only the air conditioner with wireless communication function may be configured. Further, although the wireless communication unit measures the temperature state of the installed room or the like and transmits it to the air conditioning control device 10, the temperature may be measured by an air conditioner or the like.

Further, the case where the motion sensor is used as the movement destination detection unit capable of detecting whether or not the user or the like is in the room has been described. However, as the motion sensor, for example, an infrared detection sensor that detects the movement of a person , An ultrasonic sensor capable of detecting the detailed movement of a person, a surveillance camera based on visible light information, or the like can be used.

Further, an ultrasonic sensor that transmits an ultrasonic signal from the communication control unit 17 of the air conditioning control device 10 and receives an ultrasonic signal transmitted from the outside may be provided instead of a motion sensor in each room or the like. .. The air conditioning control device 10 acquires information on the reception status of the ultrasonic signal from the air conditioning control device 10 in each room, and the position measuring unit 13 acquires air based on the acquired reception status in each room or the like. The position of the conditioned control device 10 in the house can be specified. On the contrary, in each room or the like, signals of different frequencies are transmitted from the wireless communication unit, and the position measurement unit 13 receives the signal reception status in the communication control unit 17 of the air conditioning control device 10 (each radio). The position of the air conditioning control device 10 in the house may be specified from the combined frequency of the signal from the communication unit).

Further, in the air conditioning control device 10, the set temperature determining unit 161 is provided in the moving place estimation unit 16, but this is an example and is not limited to this. In the air conditioning control device 10, the set temperature determination unit 161 may be arranged outside the movement location estimation unit 16, and the movement location estimation unit 16 and the set temperature determination unit 161 may have separate and independent configurations.

Embodiment 2. In the first embodiment, in order to estimate the current position, the arrival time difference between the air conditioning control device 10 and the radio communication units 41 to 43 installed in each room or the like is used. In the present embodiment, a method of estimating the current position will be described in the case of a short distance where there is almost no time difference between radio waves.

FIG. 3 is a diagram showing a configuration example of the air conditioning control device of the present embodiment. The difference from the first embodiment is that the air conditioning control device 10a includes a position measuring unit 13a provided with a GPS (Global Positioning System) antenna 131 instead of the position measuring unit 13. The position measuring unit 13a measures its own position based on the GPS information received by the GPS antenna 131 from the GPS satellites. The operation of the other configurations is the same as that of the first embodiment.

As described above, in the air conditioning control device 10a, the position measuring unit 13a measures its own position based on the information from the GPS satellites by using the GPS antenna 131. As a result, the air conditioning control device 10a can estimate its own current location with high accuracy based on GPS information even when the distance between the wireless communication units 41 to 43 is short. Further, even when the user moves out of the house, the current position of the air conditioning control device 10a can be measured.

Embodiment 3. In the first and second embodiments, the case where the air conditioning control devices 10 and 10a and the wireless communication units 41 to 43 installed in each room directly perform wireless communication has been described. In the present embodiment, a case where the air conditioning control devices 10 and 10a and the wireless communication units 41 to 43 communicate with each other via another device will be described.

The configuration of the air conditioning control device 10 is the same as that of the first embodiment. Here, the air conditioning control device 10 is connected to a mobile terminal 50 such as a smartphone by WiFi communication. Similarly, the wireless communication units 41 to 43 of each room or the like are also connected to the mobile terminal 50 by WiFi communication. As a result, the air conditioning control device 10 can communicate with the wireless communication units 41 to 43 of each room or the like via the mobile terminal 50, that is, using the mobile terminal 50 as a relay device by WiFi communication.

In addition, as a method of identifying its own position by the GPS function, in the air conditioning control device 10, even if the position measuring unit 13 does not have a GPS antenna, if the mobile terminal 50 has a GPS antenna, it can be carried. The position may be specified by using the GPS information from the terminal 50. If the mobile terminal 50 is a smartphone, when the user is carrying it, the position measuring unit 13 uses the GPS information of the mobile terminal 50 by regarding the mobile terminal 50 and the air conditioning control device 10 as the same position. The position can be measured.

In this way, the air conditioning control device 10 is connected to the mobile terminal 50 by WiFi communication, and is connected to the wireless communication units 41 to 43 installed in other rooms or the like via the mobile terminal 50. This makes it possible to inexpensively configure an air conditioning system and remotely control air conditioners in other rooms and the like.

Embodiment 4. In the first and second embodiments, the case where the air conditioning control devices 10 and 10a and the wireless communication units 41 to 43 installed in each room directly perform wireless communication has been described.

It was communicating directly with the conditioned controller 10. However, depending on the structure of the building and room, it is expected that there are places that are not suitable for the wireless communication environment. In such a case, the air conditioning control device 10 cannot continuously perform wireless communication with the wireless communication unit at a specific location in the house.

Therefore, in the present embodiment, as shown in FIG. 5, in each room or the like, the communication units 71 to 73 are connected to the motion sensors 21 to 23 and the air conditioners 31 to 33, respectively, and the communication units 71 to 73 are connected to the power supply. It is attached to an outlet and connects to the centralized management controller 60 via the power line. By installing the centralized management controller 60 in a place with a good communication environment, the air conditioning controller 10 can communicate with each room or the like via the centralized management controller 60.

In this way, the air conditioning control device 10 is connected to the centralized management controller 60, and is connected to the communication units 71 to 73 installed in other rooms or the like via the centralized management controller 60. As a result, even if there is a place in the house that is not suitable for wireless communication, it is possible to communicate with the air conditioner or the like in the room or the like via the centralized management controller 60.

In the air conditioning control devices 10 and 10a, the moving place estimation unit 16 monitors the personal information DB 14 every time the vital sign measurement unit 11 measures the user's vital value, and the measurement result of the vital sign measurement unit 11 is abnormal. When a value is indicated, the communication control unit 17 is notified to that effect, and the communication control unit 17 has an emergency call function of contacting a pre-registered telephone number or sending an e-mail to a pre-registered address. You may do so. The moving place estimation unit 16 compares the past measurement results stored in the personal information DB 14 with the latest measurement results, or if an allowable range is set in advance for each measurement item, the allowable range is adjusted. By comparing, abnormal values can be detected.

In the air conditioning control devices 10 and 10a, when an abnormal value is shown as a result of measuring the biometric information of the user, the registered contact information is notified to that effect, so that an emergency response can be taken immediately. For example, since it is possible to constantly detect the biological information of hypertensive patients, it is possible to make a report to the emergency contact information registered in advance when the health condition suddenly changes, and it is possible to find out especially when one elderly person lives. Since there are many cases of late death, it is possible to secure a rescue method in case of emergency.
