This Earthquake Early Warning is information including, for example, "Earthquake Early Warning", "Tsunami Warning", "Special Warning" distributed by the Japan Meteorological Agency, "Disaster / Evacuation Information" distributed by the national and local governments, and is an Earthquake Early Warning. , Tsunami warning, and special warning, which contain different breaking type information. In addition, after receiving the breaking news, the mobile phone operator or other service provider changes the breaking news to a format that can be received by the mobile terminals 1A, 1B, and 1C managed by the safety confirmation information providing device 2, or additional information. Can also be added.

In addition, the Earthquake Early Warning uses a service that simultaneously delivers messages to mobile terminals 1A, 1B, 1C (telephones, smartphones, etc.) in a specific area in a manner that is not easily affected by congestion, and ordinary e-mail. Includes those using the service and / or both. In addition, the emergency bulletin is a "special warning about weather, etc." issued when heavy rain, storm surge, storm surge, waves, blizzard, heavy snow are expected to occur once every few decades, and serious damage to the residential area. Includes "special warnings regarding eruptions" issued when an eruption occurs or is expected, and / or both. When an earthquake, tsunami, "special warning about weather, etc." and "special warning about eruption" are announced, the Japan Meteorological Agency usually automatically sends Earthquake Early Warnings, tsunami warnings, and special warnings to mobile phone operators, respectively. The mobile phone operator broadcasts emergency early warnings to the target area all at once. In addition, highly urgent information related to disasters such as evacuation advisories and evacuation orders due to disasters is created as disaster / evacuation information from the national or local governments, and is similarly distributed to the target area via mobile phone operators. NS.

As shown in FIG. 2, the mobile terminals 1A, 1B, and 1C have a communication circuit 102, a GPS function unit 103, a control unit 104, a memory 105, a power supply control unit 106, a display unit 107, an operation unit 108, and an audio input / output unit 109. And a bus 101 connecting each part. Internal control and data exchange of the mobile terminals 1A, 1B and 1C are performed via the bus 101. Bus 101 has a control bus and a data bus. The transmission of data between each unit is executed via the bus 101. The communication circuit 102 executes data transmission / reception with the base station of the mobile phone operator via antennas (not shown) in the mobile terminals 1A, 1B, and 1C. The communication circuit 102 outputs the data acquired via the network 1000 to the control unit 104 via the bus 101, and sends the data acquired from the control unit 104 via the bus 101 to the network 1000.

The GPS function unit 103 calculates the coordinates indicating the positions of the mobile terminals 1A, 1B, and 1C on the ground by processing the signals received from the GPS satellites via the antennas in the mobile terminals 1A, 1B, and 1C.

The memory 105 stores programs such as an operating system, a map application (hereinafter referred to as "app") and a safety confirmation mode application, and data that may be used in a mobile terminal such as e-mail, an address book, and user information. .. Further, the memory 105 stores general map data and evacuation map data.

General map data includes basic map data such as roads, sidewalks, and passages placed on the ground, and restaurants, commercial facilities, stations, buildings, government offices, tourist spots, and emergency evacuation displayed on the map indicated by the basic map data. Includes both attached information about the location etc. That is, the general map data includes information for identifying general commercial facilities and the like. The structure of this general map data is a layer structure composed of basic road data, detailed road data, etc. constituting the basic map data, and attached information such as building data, character data, shape data, background data, etc. It has become.

The simplest evacuation map data is a so-called blank map containing evacuation site or geolocation information of the evacuation center.

The evacuation map data includes publicly available safety data on disaster prevention. This safety data meets the new earthquake resistance standards based on the Building Standards Act (Revision of the Building Standards Act Enforcement Ordinance on June 1, 1981) for the applicable building or area, or June 1, 2000 (2000). Buildings that were built in accordance with the Building Standards Act of Japan and the revision of the Construction Ordinance, or certified as conforming to the standards of the "National Network Committee for Promotion of Seismic Diagnosis and Repair of Existing Buildings" (abbreviated as "National Seismic Network Committee") It is data indicating whether a plate related to an object has been issued or whether the building has the Tokyo Metropolitan Earthquake Resistant Mark. Furthermore, in this map data, in addition to the publicly obtained information as described above, information related to disaster prevention safety by independent investigation or verification by the evacuation map data creator can be added to a specific building or. It is attached to the whole area or a part of a specific map. For buildings or areas where the safety of these disaster prevention has been confirmed, by displaying the icons of predetermined marks and plates on the map, the user can check the safety of the building in which he / she is located at that time. It is possible to confirm, and such a recommended evacuation site and its vicinity are designated as a recommended evacuation site as a relatively safe place. On the other hand, for example, recommended evacuation of general private houses, metropolitan houses, etc. (hereinafter referred to as "private houses, etc.") in buildings with a plate related to standards conformity certified buildings or with the Tokyo Metropolitan Earthquake-Resistant Mark. Some locations are not considered suitable for general users. Therefore, it is important to treat such private houses separately from places where general users such as large-scale hotels and office buildings can freely enter. Furthermore, the evacuation map data includes information on evacuation shelters for staying for a certain period of time after an emergency evacuation and ensuring the living environment of evacuees, in addition to the evacuation shelters. The information on this evacuation shelter can be used to check the location, name, response capability, etc. even in normal times, and when moving to the recommended evacuation shelter and then using normal route search means. It becomes the target point of.

When the safety confirmation mode application receives the emergency breaking news, the operation mode of the mobile terminals 1A, 1B, and 1C is switched to the safety confirmation mode. The safety confirmation mode application activates the map application and displays the safety information received from the safety confirmation information providing device 2. This safety confirmation mode application is automatically activated when the power of the mobile terminals 1A, 1B, and 1C is turned on, and no operation for activating the safety confirmation mode application by the user is required. The safety confirmation mode application may be configured to be activated only when the user performs an operation for activating the safety confirmation mode application on the mobile terminals 1A, 1B, and 1C. Further, this safety confirmation mode application can also select whether or not to activate the safety confirmation mode according to the content of the received emergency breaking news. The map application is for displaying the position of each user who possesses the pre-registered mobile terminals 1A, 1B, and 1C.

The mobile terminal 1C displays the position marks 501, 502, 503 of the mobile terminals 1A, 1B and 1C after receiving the emergency bulletin, and the movement history marks 601 and 603 of the mobile terminals 1A, 1B and 1C before and after receiving the emergency bulletin. Displayed in unit 107. Further, the mobile terminal 1C is the name of a user who has the mobile terminals 1A, 1B, 1C in the vicinity of the position marks 501, 502, 503 of the mobile terminals 1A, 1B, 1C (“Mr. A”, “Mr. B”, The character indicating "Mr. C") is displayed. Further, the mobile terminal 1C displays the earthquake occurrence area mark 511 indicating the area where the earthquake has occurred on the display unit 107 based on the contents of the emergency breaking news. Then, the mobile terminal 1C displays the danger mark AL surrounding the position mark 502 of the mobile terminal 1B possessed by the user who is determined to be dangerous as a result of the safety confirmation determination on the display unit 107. As a result, the user who possesses the mobile terminal 1C (“Mr. C”) can recognize that the user who possesses the mobile terminal 1B (“Mr. B”) is in a dangerous state.

Next, the safety confirmation information providing process executed by the safety confirmation information providing device 2 according to the present embodiment will be described with reference to FIGS. 7 and 8. This safety confirmation information providing process is started when the power is turned on to the safety confirmation information providing device 2. Further, each step shown in the flowchart shown in FIG. 7 is sequentially processed by the control unit 201 reading and executing the program for safety confirmation processing stored in the memory 202. First, the position information acquisition means 2011 acquires the respective position information from the mobile terminals 1A, 1B, and 1C by transmitting the position information request to the mobile terminals 1A, 1B, and 1C (step S101). Next, the position information acquisition means 2011 records the acquired position information of each of the mobile terminals 1A, 1B, and 1C in the memory 202 (step S102).

Subsequently, the emergency breaking news receiving means 2012 determines whether or not the emergency breaking news has been received (step S103). If it is determined by the emergency breaking news receiving means 2012 that the emergency breaking news has not been received (step S103: No), the process of step S101 is executed again. If you use push messages that have been diversified in recent years, it does not seem that you are explicitly determining whether to receive an earthquake early warning, but when a specific push message is received by any mobile terminal, the earthquake early warning is received. Since it can be determined to be received, it can be replaced with the step (step S103) of determining whether or not the emergency breaking news has been received.

On the other hand, when it is determined by the emergency breaking news receiving means 2012 that the emergency breaking news has been received (step S103: Yes), the position information acquisition means 2011 acquires the position information of the mobile terminals 1A, 1B, 1C (step S104). The acquired position information is recorded in the memory 202 (step S105).

After that, the determination means 2014 determines whether or not the safety of each user possessing the mobile terminals 1A, 1B, and 1C can be determined based on the acquired position information of the mobile terminals 1A, 1B, and 1C (step S106). .. Here, N of each of the mobile terminals 1A, 1B, and 1C acquired by the determination means 2014 repeatedly N (N is a positive integer) times at a preset time interval after receiving the emergency bulletin to determine the safety of each user. Suppose that individual location information is required. In this case, the determination means 2014 determines that the safety determination of each user is impossible if the number of repetitions of location information acquisition after receiving the emergency breaking news is less than N times. On the other hand, the determination means 2014 determines that the safety determination of each user is possible if the number of repetitions of location information acquisition after receiving the emergency breaking news reaches N times. When the determination means 2014 determines that the safety determination of the user is impossible (step S106: No), the process of step S104 is executed again.

On the other hand, it is assumed that the determination means 2014 determines that the safety determination of the user is possible (step S106: Yes). In this case, the determination means 2014 determines the mobile terminals 1A, 1B, and 1C based on the history of the position information before and after receiving the emergency bulletin among the history of the position information of the mobile terminals 1A, 1B, and 1C stored in the memory 202. The safety of each possessing user is determined (step S107). Next, the determination means 2014 records the safety information indicating the determination result in the memory 202 (step S108).

Subsequently, the safety information notification means 2015 determines whether or not the safety information acquisition request has been received from the mobile terminals 1A, 1B, and 1C (step S109). If it is determined by the safety information notification means 2015 that the safety information acquisition request has not been received (step S109: No), the process of step S109 is executed again.

On the other hand, when it is determined that the safety information acquisition request has been received (step S109: Yes), the safety information notification means 2015 executes the authentication process for the mobile terminals 1C (1A, 1B) from which the safety information acquisition request is transmitted. (Step S110). Here, the safety information notification means 2015 includes terminal identification information and passwords given to the mobile terminals 1A, 1B, and 1C stored in advance in the memory 202, and terminal identification information and password included in the safety information acquisition request. Determine if they match. Then, when the terminal identification information and the password stored in advance in the memory 202 and the terminal identification information and the password included in the safety information acquisition request match, the safety information notification means 2015 is the source of the safety information acquisition request. Allows transmission of safety information to mobile terminals 1C (1A, 1B). When it is determined by the safety information notification means 2015 that the transmission of the safety information is not permitted to the mobile terminals 1C (1A, 1B) of the transmission source of the safety information acquisition request (step S111: No), the process of step S109 is executed again. Will be done.

On the other hand, it is assumed that the safety information notification means 2015 determines that the transmission of the safety information to the mobile terminals 1C (1A, 1B) of the transmission source of the safety information acquisition request is permitted (step S111: Yes). In this case, as shown in FIG. 8, the safety information notification means 2015 refers to the memory 202 and specifies the history of the position information and the safety information before and after the reception of the pre-registered user's emergency breaking news (step S112). ..

After that, the safety information notification means 2015 transmits the history of the position information and the safety information before and after receiving the emergency breaking news of the user registered in advance to the mobile terminals 1C (1A, 1B) of the transmission source of the safety information acquisition request (1A, 1B). Step S113).

Next, the safety information notification means 2015 determines whether or not there is an instruction to end the provision of the safety information to the users of the mobile terminals 1A, 1B, and 1C of the safety information (step S114). This safety information provision end instruction is input to the safety confirmation information providing device 2 by, for example, the user of the safety confirmation information providing device 2 performing an operation for terminating the provision of the safety information to the user. If it is determined that there is no safety information provision end instruction (step S114: No), the safety information notification means 2015 executes the process of step S109 again. On the other hand, when it is determined by the safety information notification means 2015 that the safety information provision end instruction has been given (step S114: No), the process of step S101 is executed again.

Next, the mobile terminal control process executed by the mobile terminals 1A, 1B, and 1C according to the present embodiment will be described with reference to FIG. This mobile terminal control process is started when the power is turned on to the mobile terminals 1A, 1B, and 1C. Further, each step shown in the flowchart shown in FIG. 9 is sequentially processed by the control unit 104 reading and executing a program for mobile terminal control processing stored in the memory 105. First, the position information generation / transmission means 1045 determines whether or not a position information request has been received from the safety confirmation information providing device 2 (step S201). When it is determined by the position information generation transmission means 1045 that the position information request has not been received (step S201: No), the process of step S204 described later is executed.

On the other hand, it is assumed that the position information generation / transmission means 1045 determines that the position information request has been received (step S201: Yes). In this case, the positioning means 1046 causes the GPS function unit 103 to calculate the coordinates indicating the current positions of the mobile terminals 1A, 1B, and 1C, and acquires the coordinates calculated by the GPS function unit 103 (step S202).

Next, the position information generation transmission means 1045 generates position information including the coordinates indicating the positions of the mobile terminals 1A, 1B, and 1C acquired by the positioning means 1046, and transmits the position information to the safety confirmation information providing device 2 (step S203). ..

Subsequently, the emergency breaking news receiving means 1041 determines whether or not the emergency breaking news has been received from the disaster management server 3 (step S204). If it is determined by the emergency breaking news receiving means 1041 that the emergency breaking news has not been received (step S204: No), the process of step S201 is executed again. On the other hand, when it is determined that the emergency breaking news receiving means 1041 has received the emergency breaking news (step S204: Yes), the operation mode switching means 1043 switches the operation mode of the mobile terminals 1A, 1B, 1C to the safety confirmation mode (step S205). ).

After that, the safety information acquisition means 1047 determines whether or not there is a safety confirmation command (step S206). This safety confirmation command is, for example, an operation for a user possessing the mobile terminals 1A, 1B, 1C to display the safety information of the user registered in advance on the operation unit 108 on the display unit 107. It is input to 1A, 1B and 1C. When it is determined by the safety information acquisition means 1047 that there is no safety confirmation command (step S206: No), the process of step S210 described later is executed. On the other hand, when the safety information acquisition unit 1047 determines that the safety confirmation command has been issued (step S206: Yes), the safety information acquisition unit 1047 transmits the safety information acquisition request to the safety confirmation information providing device 2 (step S207).

Next, the safety information acquisition unit 1047 determines whether or not the history of position information and the safety information have been received from the safety confirmation information providing device 2 (step S208). When the safety information acquisition unit 1047 determines that the history of the position information and the safety information have not been received (step S208: No), the process of step S207 is executed again. On the other hand, it is assumed that the safety information acquisition unit 1047 determines that the history of the location information and the safety information have been received (step S208: Yes). In this case, the safety information acquisition means 1047 causes the display unit 107 to display the movement history and the safety information of the user registered in advance by using the received location information history and the safety information (step S209).

Subsequently, the position information generation / transmission means 1045 determines whether or not there is a safety confirmation mode release command (step S210). This safety confirmation mode release command is issued to the mobile terminals 1A, 1B, 1C by, for example, a user having the mobile terminals 1A, 1B, 1C performing an operation for canceling the safety confirmation mode on the operation unit 108. Entered. Alternatively, if the users of the mobile terminals 1A, 1B, and 1C do not want to confirm the safety for some reason, it is possible to set in advance not to activate the safety confirmation mode (the setting screen is not shown). .. When the position information generation transmission means 1045 determines that the safety confirmation mode release command has been given (step S210: Yes), the position information generation transmission means 1045 executes the process of step S201 again. On the other hand, when the position information generation transmission means 1045 determines that there is no safety confirmation mode release command (step S210: No), it determines whether or not the position information request has been received (step S211). If it is determined by the position information generation transmission means 1045 that the position information request has not been received (step S211: No), the process of step S206 is executed again.

On the other hand, it is assumed that the position information generation transmission means 1045 determines that the position information request has been received (step S211: Yes). In this case, the positioning means 1046 acquires the coordinates calculated by the GPS function unit 103 (step S212), and the position information generation transmission means 1045 generates the position information of the mobile terminals 1A, 1B, 1C and provides the safety confirmation information. It is transmitted to the device 2 (step S213). After that, the process of step S206 is executed again.

As described above, according to the safety confirmation information providing device 2 according to the present embodiment, the determination means 2014 is based on the history of the position information before and after the time when the emergency breaking news is received by the emergency breaking news receiving means 2012. , The safety of each user of the mobile terminals 1A, 1B, and 1C is determined. Then, the safety information notification means 2015 provides the safety information including the determination result by the determination means 2014 together with the position information after the emergency breaking news is received by the emergency breaking news receiving means 2012, as well as the mobile terminal 1C as a pre-registered contact. Can be sent to. As a result, after the occurrence of a disaster, the user of the mobile terminal 1C can quickly and easily grasp the safety of the users of the other mobile terminals 1A and 1B based on the received safety information and the location information.

(Modification example)
Although the embodiments of the present invention have been described above, the present invention is not limited to the configuration of the above-described embodiments.

In the above embodiment, the transmission of the position information from the mobile terminals 1A, 1B, 1C to the safety confirmation information providing device 2 is performed in the position information request (see steps S1, S4, S7, S17, S20, S23 in FIG. 4). It was done in response. However, the present invention is not limited to this, and the mobile terminals 1A, 1B, and 1C may be configured to spontaneously and continuously transmit the position information at regular intervals (for example, every 30 minutes or 1 hour).

By doing so, the safety confirmation information providing device 2 can constantly grasp the positions of the mobile terminals 1A, 1B, and 1C, and can continue to grasp the position information of each terminal before and after receiving the emergency breaking news. It will be. In this case, switching to the safety confirmation mode (S205 to S210) in the mobile terminals 1A, 1B, and 1C becomes unnecessary.

Therefore, when an Earthquake Early Warning is issued only to a specific area (for example, an area with a seismic intensity of 5 lower or higher in the Earthquake Early Warning), the positions of the mobile terminals 1A, 1B, and 1C immediately before and after that are the specific areas. The safety confirmation operation can be performed only when the vehicle is located near the area, and it is possible to quickly perform a process different from the process for the mobile terminal in the area unrelated to the area. Further, the mobile terminal control process (see FIG. 9) is simplified, and the safety confirmation information providing device 2 can determine the safety.

Further, in the case where the safety confirmation information providing device 2 constantly intermittently grasps the positions of the mobile terminals 1A, 1B, and 1C in this way, the position information is periodically sent immediately after the occurrence of the emergency bulletin. When a movement of a predetermined distance (for example, 100 m) or more is confirmed, it is possible to determine that the user who possesses the mobile terminals 1A, 1B, and 1C has moved and is in a safe state.

Here, the reason for setting the threshold value of movement of a predetermined distance is that different position information is sent to the safety confirmation information providing device 2 even when there is no movement in the mobile terminals 1A, 1B, and 1C due to an error of GPS signals or the like. Because it may be done.

Further, in the case of adopting this configuration, if the movement of a predetermined distance or more is confirmed immediately after the occurrence of the emergency breaking news, the safety can be confirmed. Therefore, the position information acquisition in the safety confirmation information providing device 2 is acquired. It is also possible to make a judgment in a relatively short time without relying on the number of repetitions.

Further, a different mode may be considered for displaying the safety information for the user registered in advance.

That is, the e-mail address and telephone number related to the person to whom the user wants to notify the safety information are registered in advance in the safety confirmation information providing device 2, and the safety confirmation information providing device 2 is pre-registered after the emergency bulletin is generated. Configure to send voice or text safety information to email addresses and phone numbers.

For example, when the user of the mobile terminal 1A wants to convey the safety confirmation information to the user of the mobile terminal 1B, the telephone number of the mobile terminal 1B or the e-mail address (xyz@abc.co.jp) of the user is used as the safety confirmation information providing device. Pre-register in 2.

In this way, the safety confirmation information providing device 2 can send an SMS text message or a message to the mobile terminal 1B after the safety confirmation information of the mobile terminal 1A is generated, and the user of the mobile terminal 1B can send an SMS text message or a message. To the e-mail address (xyz@abc.co.jp), for example, "I found that the mobile terminal 1A was moved a considerable distance after the earthquake. If you have this terminal, the user "It seems to be safe." Or "It turned out that the mobile terminal 1A has not been moved a considerable distance after the earthquake. The final position information received from this terminal is latitude xx.xxx, longitude yy. You can send the message ".yyyyyyy."

By the way, if the position information of the mobile terminals 1A, 1B, and 1C is not updated after receiving the emergency breaking news, various reasons may be considered and the cases may be shown in 1 to 4 below.
1. 1. Communication line failure at the site 2. The battery of the mobile terminal is dead or malfunctions. When the mobile terminal is outside the communication service area 4. Only short-distance travel within a narrow area such as an evacuation site or building

However, since the safety has not been confirmed by the safety judgment by the safety confirmation information providing device 2, the user may be placed in a situation where the user cannot move around the final reception position information from the mobile terminals 1A, 1B, and 1C. By displaying or contacting the user who has registered the position information of the point in advance, it becomes easy to search for a user who cannot be confirmed as safe, and lifesaving or early confirmation of the user's safety is promoted.

As a further modification, the map data stored in the memory 105 may be pre-installed at the time of shipment of the mobile terminals 1A, 1B and 1C, or may be connected to the Internet after the mobile terminals 1A, 1B and 1C are shipped. It may be downloaded from the map data server. Further, the mobile terminals 1A, 1B, and 1C may sequentially download the map data from the map data server to the memory 105 and update the map data stored in the memory 105 each time the emergency bulletin is received.

In the embodiment, an example in which the positioning means 1046 performs the positions of the mobile terminals 1A, 1B, and 1C based on the output from the GPS function unit 103 has been described. However, not limited to this, the positioning means 1046 uses triangulation to obtain the relative distance difference from the plurality of base stations to the mobile terminals 1A, 1B, 1C from the strength of the radio waves received from the plurality of base stations. The positions of the mobile terminals 1A, 1B, and 1C may be detected.

Further, various functions of the safety confirmation information providing device 2 according to the present invention can be realized by using a normal computer system without using a dedicated system. For example, a program for performing the above operation is stored and distributed to a computer connected to a network on a non-temporary recording medium (for example, CD-ROM: Compact Disc Read only memory) that can be read by a computer system. Then, by installing the program in the computer system, the safety confirmation information providing device 2 that executes the above-mentioned processing may be configured.

Also, the method of providing the program to the computer is arbitrary. For example, the program may be uploaded to a bulletin board system (BBS) of a communication line and distributed to a computer via the communication line. Then, the computer starts this program and executes it in the same manner as other applications under the control of the OS. As a result, the computer functions as the safety confirmation information providing device 2 that executes the above-mentioned processing.

Although the embodiments and modifications of the present invention (including those described in the description; the same shall apply hereinafter) have been described above, the present invention is not limited thereto. The present invention includes a combination of embodiments and modifications as appropriate, and modifications thereof as appropriate.
