Description

  The present invention relates to a safety information service system in which a user registers safety information at the time of a disaster and answers a safety information inquiry from a third party. In particular, the present invention uses a system that provides a navigation service by communication, and at the time of a disaster. The route search server switches to the safety information service for a predetermined period, the safety information is registered in the route search server from the mobile terminal device used by the subscriber, and the safety of the desired subscriber from the mobile terminal device used by other subscribers The present invention relates to a safety information service system, a route search server, and a mobile terminal device that can inquire information.

  In recent years, disasters such as typhoons and torrential rains due to abnormal weather related to changes in the global environment have occurred frequently, and the scale of disasters has also increased. The occurrence of large-scale earthquake disasters has been pointed out in the past, and disasters and incidents that cause large local damage such as earthquakes and terrorism occur frequently around the world. In particular, major disasters such as tsunamis and earthquakes are frequent in Asian countries. Also, as symbolized by terrorism at trade centers in the United States, terrorist damage has been reported in various countries around the world. Even in Japan, it is considered that such a disaster will not occur at any time.

  Under such circumstances, local governments are also examining disaster countermeasure systems for confirming the safety information of residents in the event of a disaster such as an earthquake or typhoon, and smoothly promoting rescue and recovery activities. Conventionally, various techniques have been proposed in which personal safety information can be confirmed and browsed by a communication function such as the Internet when a disaster occurs.

  For example, the following Patent Document 1 (Japanese Patent Laid-Open No. 2004-48094) discloses a disaster information confirmation system capable of efficiently confirming various information at the time of a disaster. When a disaster occurs, this disaster information confirmation system provides a disaster information acquisition unit that acquires information that identifies the area in which the disaster has occurred, and a disaster victim terminal that is used by the victim in the acquired area. A registration request transmission unit that transmits disaster request information and registration request information that prompts the user to register the safety information of the disaster victim, and within a predetermined time after the registration request transmission unit transmits the registration request information. A non-response terminal specifying unit that monitors a response from a person terminal and specifies a disaster victim terminal that does not transmit safety information within the predetermined time, and a registration request transmission unit is provided for the identified disaster victim terminal The registration request information is transmitted again.

  That is, according to the disaster information confirmation system disclosed in Patent Document 1, the disaster occurrence information acquired by the disaster information acquisition means and the registration request information are transmitted to the disaster victim terminal. Can be sent. Moreover, since the disaster victim terminal which does not transmit safety information with respect to registration request information is identified and registration request information is transmitted again to the identified disaster victim terminal, disaster victim information can be collected more reliably.

  Moreover, according to the disaster information confirmation system disclosed in Patent Document 1, the victim request terminal that does not register the safety information is identified even though the registration request transmission means transmits the registration request information several times. Since the instruction information for instructing the disaster victim terminal to transmit the location information is transmitted, for example, it becomes possible to acquire the location information of the disaster victim who is in a serious state due to the disaster and cannot register the safety information.

Patent Document 2 (Japanese Patent Laid-Open No. 2002-312879) below discloses a safety confirmation system that provides disaster confirmation and personal safety confirmation when there is insufficient information due to confusion at the time of a disaster or when there is no communication means. . In this safety confirmation system, the safety confirmation device includes a disaster detection device, a processing device, and a database. When the disaster detection device detects a disaster larger than a preset size, it notifies the processing device. The processing device refers to the database and issues safety confirmation information by e-mail to the response terminal in the area where the activated disaster detection device is installed. The response terminal is configured to respond that it or the company or group is safe.

  The processing device posts a list of safety confirmations and response statuses for each individual, company, and group on the network, transmits confirmation information again to individuals and groups that do not respond, and updates the information in real time. The confirmation terminal is a terminal used for inquiries from a third party, and browses information posted on the network by the processing device to grasp the situation of the disaster area.

  Furthermore, the following Patent Document 3 (Japanese Patent Laid-Open No. 2003-198751) discloses a safety confirmation system that can easily collect information on safety status from victims in a disaster occurrence area when a disaster occurs. Has been. This safety confirmation system determines that a disaster has occurred based on the disaster occurrence detection information from the disaster occurrence detection device, and whether or not the victim (user) lives in the area where the disaster occurred. An e-mail for inquiries about safety is transmitted, and the user sends back an e-mail. In this way, it is possible to determine whether each user is alive immediately after a disaster occurs.

  Recently, the penetration rate of mobile phones has increased, and it is possible to receive telephone and data communication services anytime and anywhere within the range of any base station. In addition, the hardware and software functions of mobile phones have been enhanced, and the functions of conventional mobile terminal devices have also been increased. Furthermore, a mobile phone called the third generation is equipped with a GPS receiver and can measure the current position (latitude / longitude) where the mobile phone itself is located, and there is also a navigation system using the mobile phone as a terminal device. It has been put into practical use. Various systems that use such a positioning system to confirm the positions of elderly people, children, and the like, and to confirm the positions at the time of reporting in cases such as crimes and fires and accidents have been studied.
