Safety information providing system

The present invention relates to a system that provides information on the safety of a victim registered in advance in the event of a large-scale disaster, and particularly in a situation where communication lines and information are easily confused immediately after the occurrence of a disaster, the safety information of the victim. It is related to a safety information providing system that can provide such information accurately and promptly.

Lifeline companies such as local governments, electric power supply companies and gas supply companies, non-profit organizations, etc. provide disaster prevention information, disaster prevention support work, response work in the event of a disaster, etc. to ensure the safety of local residents. It is planned. In particular, today, using the Internet, disaster prevention portal sites that provide the above-mentioned various operations have been set up to provide highly convenient services to users who are local residents.

As one of such disaster prevention operations using the Internet, an online system has been proposed in which the safety information of each local resident can be confirmed on the above disaster prevention portal site in the event of a disaster.

This is because in the event of a large-scale disaster such as an earthquake, the number of telephones for safety confirmation will increase rapidly, causing confusion such as congestion due to line congestion, making it impossible to confirm the safety of the victims. It is strongly desired to put it into practical use because it is difficult to obtain the safety information of each individual victim from the information from TV broadcasting and radio broadcasting.

The safety information provision system described in Patent Document 1 allows local residents to register for use on a server installed on the Internet in advance, and if they become victims of a large-scale disaster, they can use a mobile terminal, etc. It can be used to send and store its own safety information, etc. to the above server, and persons other than the victim (for example, the victim's family, friends, acquaintances, etc.) can access the above server and store it. The feature is that the safety information of the victim can be searched and confirmed.

In this safety information providing system, it is possible to use the WEB browser of a computer terminal or a mobile terminal to perform usage registration, safety information inquiry, and various information retrieval, which is highly convenient for users. In addition, system construction costs and operating costs are kept low.

<p> By the way, when a large-scale disaster occurs, a large number of telephone calls for contacting rescue and firefighting activities and confirming the safety of the victims are sent to the disaster area immediately after the disaster. Communication lines are often congested around the area, resulting in congestion.</p><p> Such congestion can occur on any line such as a fixed telephone, a mobile phone, and a PHS (Personal Handy-phone System).</p><p> In such a situation, even if the victim tries to send his / her own safety information to the server using the above-mentioned safety information providing system, there arises a problem that the server cannot be accessed due to the congestion of the communication line. ..</p><p> In order to avoid congestion of communication lines in the event of a disaster, attempts have been made to multiplex lines by introducing satellite communication lines and to increase the number of line aggregation devices, but the cost of the system is high. It is difficult to realize because of the increase, and the current situation is that communication lines are often congested for several hours to several days after a disaster occurs.</p><p> Therefore, in reality, many existing safety information providing systems collect safety information of disaster victims when a certain period of time has passed since the disaster occurred and the congestion state of the communication line has healed, for example, three days after the disaster occurred. In many cases, the operation is diligent, as long as it is in a state where it can be performed.</p><p> However, the families of the victims want to know the safety situation of the victims as soon as possible, even if there is little information, and the victims themselves are also safe and injured. We would like to use the safety confirmation system to promptly notify us of what has happened. Furthermore, even if a person performing restoration work at a disaster site finds a missing person or an injured person, it is necessary to promptly report using the safety confirmation system.</p><p> In response to such requests, the fact that the safety information of the victims cannot be notified or inquired at all for several hours to several days after the disaster occurs is a problem that the significance of the safety confirmation system itself is questioned. Is.</p><p> Therefore, in view of such circumstances, the present invention can immediately collect the safety information of the victims immediately after the occurrence of the disaster without being affected by the congestion state of the communication line, and disclose the safety information. It is intended to provide a possible safety information provision system.</p>

<p> As a result of diligent research in view of the above-mentioned problems, the present inventor can determine the approximate position of the victim from the communication record between the mobile phone terminal owned by the victim and the communication base station for the mobile phone.

It provides a safety information providing system including a safety information providing unit for providing the stored safety information and a safety information providing server including the safety information providing unit.</p><p> Here, the "communication record" between the mobile phone terminal and the communication base station means that the mobile phone terminal constantly transmits and receives to and from the communication base station in order to notify the position of the own terminal and confirm the communication path. It shall refer to the recording of control radio waves.</p><p> In the safety information providing system of the present invention, the service center further includes means for acquiring and storing mapping information regarding the position of a communication base station from the mobile phone carrier, and the terminal information providing unit is the mobile phone. The mapping information is provided in association with the location information of the telephone terminal.</p><p> This makes it possible to determine the position information of the mobile phone terminal from the information on which communication base station the mobile phone terminal communicated with and when, and the information on the position of the communication base station.</p><p> In the safety information providing system of the present invention, the safety information providing server further includes a disaster information storage unit that stores disaster information for each region, and the safety information providing unit associates with the safety information and said the disaster. It is characterized by providing information.</p><p> By providing not only the location information of the victim's mobile phone terminal but also the disaster information at the specified location, the safety of the victim can be notified in more detail.</p><p> In the safety information providing system of the present invention, the safety information providing server further includes a usage registration information storage unit that stores at least one of a mobile phone number and a mobile phone terminal ID as user registration information. It is characterized by that.</p><p> In addition, the terminal information acquisition unit acquires the position information of the mobile phone terminal from the service center based on the user's mobile phone number or mobile phone terminal ID stored in the usage registration information storage unit. It is characterized by.</p><p> Further, the safety information providing unit is characterized in that the safety information and the disaster information are distributed to each user based on the user's registration information stored in the usage registration information storage unit.</p><p> This makes it possible to easily identify the target mobile phone terminal of the disaster victim from the huge amount of communication records held by the service center.
