  According to this configuration, when a response signal is not received from a terminal that has transmitted a safety confirmation signal at the time of a disaster, the terminal that has transmitted the response signal is invited to provide safety information of the terminal owner that has not transmitted the response signal. It is like that. By this, when the terminal owner who sent the response signal at the time of disaster can grasp the safety of the terminal owner who has not responded, can confirm the surroundings of the terminal owner and can confirm the safety of the terminal owner who has not responded earlier There is. For example, a person who has received an information provision signal sends safety information to a server on behalf of an owner who cannot send a response signal due to loss of the terminal, or searches the surroundings to find an unidentified person earlier and rescues them. There is a case that can be. In this way, it may be possible to acquire the safety information of the person whose safety is unknown earlier and more reliably.

  Further, the second invention is the safety confirmation server according to the first invention, wherein the confirmation signal transmitting means continues to transmit the safety confirmation signal to the terminal that has not yet transmitted the response signal until the response signal is received. good. According to this configuration, since the safety confirmation signal is continuously transmitted until the response signal is received, for example, even when the terminal cannot receive the safety confirmation signal due to communication failure or the like, the signal may be received if communication is recovered. Yes, there may be a more reliable safety confirmation.

  Further, the third invention is the safety confirmation server of the first or second invention, wherein the confirmation signal transmitting means receives the response signal from the terminal that has transmitted the safety confirmation signal, and has received the response signal to the terminal. It may be configured to transmit a reception confirmation signal for confirming. According to this configuration, when a response signal is received from the terminal, a reception confirmation signal is transmitted to confirm that the response signal has been received. Therefore, the owner of the terminal knows that the response signal transmitted by the terminal has arrived reliably. You may be able to eliminate the fear of being unsure whether your safety has been confirmed.

  According to a fourth aspect of the present invention, there is provided a safety confirmation terminal comprising: a communication unit that is connected to a server so that data communication is possible; a confirmation signal receiving unit that receives a safety confirmation signal transmitted from the server; Response signal transmitting means for transmitting a response signal for the safety confirmation signal to the server, and providing signal receiving means for receiving the information providing signal for calling for the provision of safety information of the unknown person transmitted from the server that has received the response signal; It has.

  According to this configuration, when a safety confirmation signal is received during a disaster, the response signal can be transmitted to the server simply by pressing the response signal transmission means. In some cases, the server side that can transmit the response signal and receive the response signal can confirm the safety of the owner of the terminal. In addition, by receiving an information provision signal calling for the provision of safety information of an unknown person, if the unknown person is in the vicinity, provide the safety information or search the surroundings to discover the unknown person sooner There are cases where it can be rescued. Thereby, the safety information of an unknown person may be able to be acquired earlier and reliably.

  The fifth invention is the fourth invention, wherein the confirmation signal receiving means may include a light emitting means that emits light when receiving the safety confirmation signal. According to this configuration, since the light emitting means that emits light when receiving the safety confirmation signal is provided, the terminal owner can easily recognize that the safety confirmation signal has been received, and is not aware that the signal has been received. In some cases, it is possible to eliminate the risk of being unable to confirm.

  A preferred embodiment of the present invention will be described with reference to FIGS.

  A safety confirmation server 1 (hereinafter referred to as “server”) and an information terminal (safety confirmation terminal) 2 according to the present embodiment are used in a safety confirmation system 100 as shown in FIG. The safety confirmation system 100 includes a server 1, a plurality of information terminals 2, and a base station 3, and the server 1 and the plurality of information terminals 2 can perform data communication via a wide area network passing through the base station 3 and the like. It is connected to the. The safety confirmation system 100 manages the owners and locations of the information terminals 2 in which the servers 1 installed in the center 90 are scattered in various places, and checks the safety (survival) of the owners of the information terminals 2 at the time of a disaster. It is a system that can be confirmed. The wide area network is a communication network connected by a dedicated line in addition to the Internet. The communication method may be any one of radio using radio waves, sound waves and light, wired using a communication cable or a telephone line, or a combination thereof. Further, the server 1 and the information terminal 2 are not always connected, and each time a signal is transmitted / received, the mutual communication is established and the data communication is possible.

  The server 1 is installed in the center 90 and can be connected to a plurality of information terminals 2 scattered in various places so as to be able to perform data communication. The server 1 manages each information terminal 2 and, when a disaster occurs, the information terminal 2 in the disaster occurrence area. It is a server that confirms the safety of the owner. As shown in FIG. 2, the server 1 is a computer including an arithmetic device 11, a communication unit 12 (communication unit), a storage device 13 (terminal information storage unit), a display device 14, an operation unit 15, and the like.

  The arithmetic device 11 is composed of a microcomputer having a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), etc., and executes processing routines to be described later to control each device included in the server 1. It has a function to do. The communication unit 12 has a function of connecting to the information terminal 2 via the network so that data communication is possible. The storage device 13 stores terminal information related to the information terminal 2. As shown in FIG. 5, the terminal information is a data table in which at least a unique ID number assigned to each information terminal 2, the owner of the information terminal 2, and the location thereof are associated with each other. The display device 14 and the operation unit 15 are, for example, a display, a keyboard, and the like, and display a processing result of the arithmetic device 11 or input a processing command to the arithmetic device 11.

  Here, each function which the arithmetic unit 11 has will be described. The arithmetic device 11 includes a disaster detection unit 111, a disaster victim detection unit 112, a confirmation signal transmission unit 113, a safety unknown person detection unit 114, and an information provision signal transmission unit 115.

  The disaster detection unit 111 (disaster detection means) detects a disaster and identifies a disaster occurrence area. In the present embodiment, as a disaster detection method, for example, when a disaster occurs in area A in FIG. 1, a disaster notification signal is received from a disaster monitoring server (not shown) in area A or the like. Alternatively, disaster-related data may be input from the operation unit 15.

  The victim detection unit 112 (terminal detection means) detects a victim in the disaster occurrence area. Specifically, based on the terminal information stored in the storage device 13, the information terminal 2 in which the disaster occurrence area specified by the disaster detection unit 111 and the location of the information terminal 2 match is detected and detected. The owner of the information terminal 2 is determined as a victim. When a disaster victim is detected, a data table having the ID number, owner, location, and safety result of the information terminal 2 is created as a disaster victim list shown in FIG. Stored in

  The confirmation signal transmission unit 113 (confirmation signal transmission means) transmits a safety confirmation signal to all the information terminals 2 in the victim list. The safety confirmation signal is a signal that prompts the owner to press a response button 2a of the information terminal 2 described later in order to confirm the safety (survival) of the owner of the information terminal 2. Although specifically described later, the information terminal 2 that has received the safety confirmation signal displays a message for pressing the response button 2a on the liquid crystal panel, or blinks the LED lamp 2L of the response button 2a. When the response button 2a is pressed by the owner, the information terminal 2 transmits a response signal to the server 1, and the server 1 receives the response signal, so that the owner of the information terminal 2 Safety (survival) can be confirmed. In the following description, an information terminal 2 that has received a safety confirmation signal and has transmitted a response signal may be referred to as a signal-transmitted terminal, and an information terminal 2 that has not transmitted a response signal may be referred to as a signal-untransmitted terminal.

  Further, when the confirmation signal transmitting unit 113 receives the response signal, the confirmation signal transmitting unit 113 transmits a reception confirmation signal to the information terminal 2 that transmitted the response signal, and receives a response signal from the information terminal 2 that transmitted the safety confirmation signal. If not received, the safety confirmation signal is continuously transmitted to the signal non-transmission terminal until the safety of all the unknown persons detected by the unknown person detection unit 114 described later is confirmed. The reception confirmation signal is a signal that informs the information terminal 2 that the response signal transmitted to the server 1 has been received by the server 1.

  By transmitting the reception confirmation signal, the owner of the signal-transmitted terminal can grasp that the response signal is reliably transmitted to the server 1 and that his / her existence has been confirmed in the server 1. In some cases, you can eliminate the risk of being anxious about whether or not your device has been confirmed. In addition, when the response signal is not received from the information terminal 2 that has transmitted the safety confirmation signal, the communication terminal is continuously transmitted with the safety confirmation signal to the information terminal 2, so that communication failure occurs due to the disaster, and the information terminal side Even if the confirmation signal cannot be received, the safety confirmation signal can be received as soon as communication is restored. Therefore, the server 1 may be able to perform more reliable safety confirmation.

  The safety unknown person detection unit 114 (response signal receiving means, untransmitted terminal detection means, owner detection means) detects a safety unknown person based on the response signal transmitted from the information terminal 2. Specifically, the response signal transmitted from the information terminal 2 has the ID number of the transmitted information terminal 2. Then, the confirmation signal transmitting unit 113 compares the ID number of the information terminal 2 that transmitted the safety confirmation signal with the ID number included in the received response signal, and detects the signal transmitted terminal and the signal untransmitted terminal, respectively. . The owner of the detected signal non-transmission terminal is determined as an unidentified person. In addition, as shown in FIG.6 (b), the safety unknown person detection part 114 adds a safety result to said created victim list.

  In addition, when an information signal is received from the information terminal 2, the safety unknown person detection unit 114 redetects a safety unknown person based on the information signal. As will be described later, the information signal is safety information of an unknown person provided by the owner of the information terminal 2 that has received the information providing signal transmitted by the information providing signal transmitting unit 115.

  The information providing signal transmitting unit 115 (providing signal transmitting means) transmits an information providing signal to the signal transmitted terminal. The information providing signal is a signal for displaying the detected safety unknown person on the liquid crystal panel of the signal transmitted terminal and calling for providing the safety information of the displayed safety unknown person. Since the owner of the information terminal 2 that has received the information providing signal can grasp the unknown person, search the surroundings to find and rescue the unknown person earlier, or, for example, lose the information terminal 2 In some cases, the response signal cannot be transmitted, and the safety information can be transmitted to the server on behalf of the terminal owner who cannot notify the server 1 of his / her safety.

  The information terminal 2 connected to the server 1 configured as described above so as to be able to perform data communication is, for example, a portable computer such as a PDA (Personal Digital Assistant). The information terminal 2 has a response button 2a (response signal transmission means) including a liquid crystal panel 21 and an LED lamp 2L (light emission means). Based on each signal transmitted from the server 1, the information terminal 2 Character information is displayed or the LED lamp 2L of the response button 2a is blinked.

  Specifically, when receiving a safety confirmation signal from the server 1, the information terminal 2 displays a safety confirmation screen shown in FIG. 3A on the liquid crystal panel 21 and a response provided in the vicinity of the liquid crystal panel 21. The LED lamp 2L of the button 2a is blinked. The safety confirmation screen is a message screen that prompts the user to press the response button 2a such as “Please press the response button”. As a result, the owner can easily recognize that the safety confirmation signal has been received, and the owner can be prevented from noticing that the signal has been received and not transmitting the response signal. In addition, by pressing the response button 2a, a response signal is transmitted to the server 1, and it is possible to notify the server 1 of its own safety (survival). Thus, even in a confused situation at the time of a disaster, there is a case where a response signal for notifying the existence of oneself can be transmitted to the server 1 by a simple operation of pressing a button.

  Further, when the information terminal 2 receives the reception confirmation signal from the server 1, the information terminal 2 displays a reception confirmation screen shown in FIG. The reception confirmation screen is a screen having a message indicating that the safety of the server 1 has been confirmed by the server 1, such as “confirmed safety”. Thereby, the owner may be able to confirm that the response signal has been reliably transmitted to the server 1.

  When the information terminal 2 receives the information provision signal from the server 1, the information terminal 2 displays an information provision screen shown in FIG. The information provision screen is a screen on which a list of owners (unknown persons of safety) of signal non-transmitting terminals is displayed, and includes an unidentified person name 4a, a survival button 4b, and a transmission button 4c. The unknown person name 4a is the name of the owner of the terminal that has not yet transmitted the signal. The survival button 4b is a button that is displayed so as to be selectable, and is selected when notifying the server 1 that it is safe (alive) when an unknown person in the unknown person name 4a is found. . The transmission button 4c is a button that can be operated when the survival button 4b is selected and transmits an information signal for notifying the server 1 of the survival of the person whose safety is unknown.

  In this way, by receiving an information provision signal that calls for the provision of safety information of an unknown person, the received owner can provide the safety information of an unknown person or search the surroundings to find and rescue earlier You may be able to Further, for example, the safety information can be transmitted to the server on behalf of the owner who has lost the information terminal 2 and cannot transmit the response signal, and the server 1 may be able to acquire more reliable safety information.

  The liquid crystal panel that displays each screen is a touch panel display, and the screen serves as an input device. That is, by pressing the screen of each button part displayed on the screen, it reacts as if the button was actually input.

  As shown in FIG. 2, the information terminal 2 includes a response button 2a having an LED lamp 2L, a liquid crystal panel 21, a CPU 22, a RAM 23, a ROM 24, a storage device 25, a communication unit 26, and a data bus. 27 and an interface unit (hereinafter referred to as I / O) 28.

  The response button 2a is a button for transmitting a response signal, and the liquid crystal panel 21 is a touch panel type display device that displays character information. The CPU 22 is a central processing unit that performs arithmetic processing according to various commands. The RAM 23 is a volatile read / write memory for temporarily storing signals received from the server 1 and data used when the CPU 22 executes a program. The ROM 24 is a non-volatile read-only memory that stores a calculation program for operating a flowchart described later. The storage device 25 is a device that stores a unique ID number of the information terminal 2 and other data. The CPU 22, RAM 23, and ROM 24 are connected by a data bus 27 that is a signal path connecting the internal devices.

  The communication unit 26 (communication means) is a device that converts a signal sent out by a computer into a signal that can be sent via a telephone line or a LAN cable in computer communication, and returns the sent signal to a signal that can be read by a computer. Yes, connected to the server 1 by wireless or wired connection. The I / O 28 is a connection unit that directly and indirectly electrically connects the liquid crystal panel 21 and the communication unit 26 separated as modules to the CPU 22 and the like.

  Here, each function of the ROM 24 for operating a flowchart described later will be described in detail. The ROM 24 has a display area 241 (provided signal receiving means), a response signal transmitting area 242 (confirmation signal receiving means, response signal transmitting means), and a light emitting area 243 (confirmation signal receiving means). The program is stored. The program in the display area 241 is a program that receives a safety confirmation signal, a reception confirmation signal, and an information provision signal, and displays the safety confirmation screen, the reception confirmation screen, and the information provision screen shown in FIGS. The program in the response signal transmission area 242 is a program that transmits a response signal to the server 1 when the response button 2a is pressed. The program for the light emitting area 243 is a program for blinking the LED lamp 2L of the response button 2a when a safety confirmation signal is received.

  Next, operations of the server 1 and the information terminal 2 configured as described above will be described.

(Server operation)
The server 1 executes the main routine shown in FIG. 7, and first determines whether or not a disaster has been detected (A1). When no disaster is detected (A1: NO), A1 is repeated. When a disaster is detected (A1: YES), the disaster occurrence area is specified (A2). Next, the information terminal 2 in the identified disaster occurrence area is detected, and a disaster victim list is created based on the detected information terminal 2 (A3). Specifically, based on the ID number of the detected information terminal 2, the owner of the information terminal 2 is detected from the terminal information stored in the storage device 13, and the owner is determined as a victim. Then, the victim list shown in FIG. 6 is created.

  And a safety confirmation signal is transmitted with respect to all the information terminals 2 in a disaster victim list | wrist (A4). Next, it is determined whether or not a response signal has been received from the information terminal 2 that has transmitted the safety confirmation signal (A5). When the response signal is not received (A5: NO), it is determined whether or not a predetermined time has elapsed (A14). If the predetermined time has not elapsed (A14: NO), the process returns to A5 and is repeated until a response signal is received. When the predetermined time has elapsed (A14: YES), the process returns to A4, and a safety confirmation signal is transmitted again. By sending the safety confirmation signal again after a predetermined time has passed, even if the safety confirmation signal has not been received on the information terminal side due to a communication failure due to a disaster, the safety confirmation signal is sent immediately after communication is restored. You may be able to receive. Thereby, safety information may be acquired more reliably.

  When a response signal is received (A5: YES), a reception confirmation signal is transmitted to the information terminal 2 that has transmitted the response signal (A6), and an information terminal 2 that has not transmitted the response signal is detected (A7). . Specifically, the ID number of the information terminal 2 is included in the received response signal, and the ID number of the information terminal 2 that transmitted the safety confirmation signal is compared with the ID number included in the received response signal. . And a signal transmitted terminal and a signal untransmitted terminal are detected, respectively. Next, as a result of detection, it is determined whether or not response signals have been received from all information terminals that have transmitted the safety confirmation signal (A8). That is, it is determined whether there is a signal untransmitted terminal. When response signals are received from all the information terminals (A8: YES), it is determined that the safety of all the victims has been confirmed, and the process returns to A1.

  If no response signal has been received from all the information terminals (A8: NO), an unknown person is detected based on the ID number of the terminal that has not transmitted the signal (A9). After the detection, the safety result is added to the created disaster victim list (see FIG. 6B). And (A10).

  Next, it is determined whether an information signal has been received (A11). When the information signal is not received (A11: NO), it is determined that the safety information of the person with unknown safety is not received, the process returns to A10, and the safety confirmation signal is retransmitted to the information terminal 2 of the person with unknown safety again. At the same time, the information providing signal is transmitted to the signal-transmitted terminal whose safety has been confirmed. When an information signal is received from the signal-transmitted terminal (A11: YES), a person with unknown safety is redetected based on the information signal (A12). At this time, the safety result of the victim list is updated. Then, it is determined whether or not the safety of all persons whose safety is unknown in the victim list has been confirmed (A13). If it is confirmed that the safety of all persons whose safety is unknown (A13: YES), the process returns to A1. If the safety of the person with unknown safety is not confirmed (A13: NO), the process returns to A10, and the above operation is repeated until the safety of the person with unknown safety is confirmed.

(Operation of information terminal)
Next, the operation of the information terminal 2 will be described. The information terminal 2 executes the terminal-side processing routine shown in FIG. 8, and first determines whether or not a safety confirmation signal has been received from the server 1 (B1). When the safety information signal is received (B1: YES), the LED lamp 2L of the response button 2a is blinked and a safety confirmation screen is displayed on the liquid crystal panel 21 (B2). Then, it is determined whether or not the response button 2a has been pressed (B3). If the response button 2a is not pressed (B3: NO), B3 is repeated.

  When the response button 2a is pressed (B3: YES), a response signal is transmitted to the server 1 (B4). And it is determined whether the reception confirmation signal was received from the server 1 (B5). When the reception confirmation signal has not been received (B5: NO), the process returns to B4 and the response signal is transmitted again. In this way, by continuing to transmit the response signal until the reception confirmation signal for confirming that the server 1 has received the response signal is received, for example, even when the server 1 cannot receive the response signal due to communication failure or the like. If the communication is restored, a signal may be received, and a more reliable safety check may be performed. In addition, the owner may be able to grasp that the response signal transmitted by himself / herself has arrived reliably, and may be able to eliminate the fear of whether or not his / her safety has been confirmed.

  If a reception confirmation signal has been received (B5: YES), it is next determined whether an information providing signal has been received from the server 1 (B6). When the safety information signal is not received in B1 (B1: NO), the process proceeds to B6, and it is determined whether or not the information providing signal is received from the server 1. When the reception confirmation signal is received, the blinking of the LED lamp 2L is stopped, the safety confirmation screen is deleted, and the reception confirmation screen is displayed. When the information providing signal is not received (B6: NO), the process returns to B1. When the information providing signal is received (B6: YES), the information providing screen including the name of the unknown person is displayed on the liquid crystal panel 21 based on the information providing signal (B7). Then, it is determined whether or not safety information related to the person whose safety is unknown has been input by touch panel input on the liquid crystal panel 21 (B8). Specifically, it is determined whether or not the survival button 4b is selected and the transmission button 4c is pressed on the information providing screen.

  When safety information is input (B8: YES), an information signal including the safety information input to the server 1 is transmitted (B9), and the information provision screen is deleted (B10). Thereafter, the process returns to B1. When safety information is not input (B8: NO), it is determined whether a predetermined time has passed (B11). When the predetermined time has not passed (B11: NO), the process returns to B8. If the predetermined time has elapsed (B11: YES), the information providing screen is deleted (B10). Thereafter, the process returns to B1.

  As described above, in the present embodiment, the safety confirmation server (for example, the server 1) is connected to a plurality of terminals (for example, the information terminal 2) and communication means (for example, the communication unit 12) that is connected so as to be able to perform data communication. Detecting a disaster occurrence area by a terminal information storage means (for example, storage device 13) for storing terminal information including owner information of each terminal and a disaster area specifying signal received from the outside or input by an input key Disaster detection means (for example, disaster detection unit 111 of computing device 11), terminal detection means for detecting a terminal located in the disaster occurrence area (for example, disaster victim detection unit 112 of computing device 11), and detected terminal In response to the confirmation signal transmitting means (for example, the confirmation signal transmitting unit 113 of the arithmetic unit 11) for transmitting a safety confirmation signal for confirming the safety of the owner of the terminal, Whether or not a response signal is received from the response signal receiving means (for example, the safety unknown person detection unit 114 of the computing device 11) that receives a response signal transmitted by the operation of the terminal owner and the terminal that transmitted the safety confirmation signal. Based on the untransmitted terminal detecting means for detecting the terminal that has not yet transmitted the response signal (for example, the unidentified person detection unit 114 of the arithmetic unit 11) and the terminal information storage means, Providing the safety information of the owner of the detected response signal non-transmitting terminal to the owner detecting means for detecting the owner (for example, the safety unknown person detection unit 114 of the computing device 11) and the terminal that has transmitted the response signal. Providing signal transmitting means (for example, the information providing signal transmitting unit 115 of the arithmetic device 11) for transmitting an information providing signal for calling for information.

  According to this configuration, when a response signal is not received from a terminal that has transmitted a safety confirmation signal at the time of a disaster, the terminal that has transmitted the response signal is invited to provide safety information of the terminal owner that has not transmitted the response signal. It is like that. By this, when the terminal owner who sent the response signal at the time of disaster can grasp the safety of the terminal owner who has not responded, can confirm the surroundings of the terminal owner and can confirm the safety of the terminal owner who has not responded earlier There is. For example, a person who has received an information provision signal sends safety information to a server on behalf of an owner who cannot send a response signal due to loss of the terminal, or searches the surroundings to find an unidentified person earlier and rescues them. There is a case that can be. In this way, it may be possible to confirm the safety information of the person whose safety is unknown earlier.

  Moreover, the confirmation signal transmission means of this Embodiment is the structure which continues transmitting a safety confirmation signal to the terminal which has not transmitted a response signal until a response signal is received. According to this configuration, since the safety confirmation signal is continuously transmitted until the response signal is received, for example, even when the terminal cannot receive the safety confirmation signal due to communication failure or the like, the signal may be received if communication is recovered. Yes, there may be a more reliable safety confirmation.

  Furthermore, the confirmation signal transmission means of this embodiment is configured to transmit a reception confirmation signal for confirming that the response signal has been received to the terminal when receiving the response signal from the terminal that has transmitted the safety confirmation signal. According to this configuration, when a response signal is received from the terminal, a reception confirmation signal is transmitted to confirm that the response signal has been received. Therefore, the owner of the terminal knows that the response signal transmitted by the terminal has arrived reliably. You may be able to eliminate the fear of being unsure whether your safety has been confirmed.

  In addition, the safety confirmation terminal (for example, the information terminal 2) of the present embodiment receives a communication means (for example, the communication unit 26) that is connected to the server so that data communication is possible, and a safety confirmation signal transmitted from the server. Confirmation signal receiving means (for example, a program for the response signal transmission area 242 and a program for the light emitting area 243) and a response signal transmission means for transmitting a response signal for the safety confirmation signal to the server by a pressing operation when receiving the safety confirmation signal ( For example, a provision signal receiving means (for example, a response button 2a or a program of the response signal transmission area 242) and a provision signal receiving means for receiving an information provision signal for calling for provision of safety information of an unknown person transmitted from the server that has received the response signal (for example, Display area 241 program).

  According to this configuration, when a safety confirmation signal is received during a disaster, the response signal can be transmitted to the server simply by pressing the response signal transmission means. In some cases, the server side that can transmit the response signal and receive the response signal can confirm the safety of the owner of the terminal. In addition, by receiving an information provision signal that calls for the provision of safety information for persons with unknown safety, the surrounding people can provide safety information or search the surroundings to find and rescue earlier There is. Thereby, the safety information of an unknown person may be able to be confirmed earlier.

  Moreover, this Embodiment is a structure provided with the light emission means (for example, LED lamp 2L) which light-emits, when a confirmation signal receiving means receives a safety confirmation signal. According to this configuration, since the light emitting means that emits light when receiving the safety confirmation signal is provided, the terminal owner can easily recognize that the safety confirmation signal has been received, and is not aware that the signal has been received. You may be able to get rid of the worry of not being able to confirm.

  Moreover, although this invention was demonstrated based on suitable embodiment, this invention can be changed in the range which does not exceed the meaning. That is, in this embodiment, the location of the information terminal 2 is stored in the storage device 13 as terminal information, and the information terminal 2 in the disaster occurrence area is detected. For example, the GPS (Global Positioning System) ) May be used to detect the information terminal 2 in the disaster occurrence area. In this case, even when the owner moves to a remote area, the location of the information terminal 2 can be detected, and more accurate safety information may be obtained.

  In the present embodiment, the safety confirmation terminal is an information terminal such as a PDA, but may be a mobile phone, for example. Furthermore, in the present embodiment, when providing information on the safety of an unknown person in the information terminal 2, only the survival is reported. However, more specific information, for example, the degree of injury, etc. You may make it alert | report to. In this case, information such as a countermeasure method may be provided to the information provider. Furthermore, when a predetermined time has elapsed since the server 1 detected a disaster, the above-described operation may be stopped, and the person with unknown safety at that time may be notified to the disaster occurrence area. For example, since it may be difficult to easily find an unidentified person after a certain period of time, at that point in time, it will be more fully known by notifying the local area where the disaster occurred. May be able to conduct an investigation.

  Further, every time an information providing signal is received from the information terminal 2, the received result may be displayed on the display device 14 of the server 1, or a list of unidentified persons may be displayed on the screen at predetermined intervals. May be. In this case, the server 1 side can always grasp the latest person with unknown safety, and may be able to accurately indicate the person with unknown safety to search in the disaster occurrence area. Therefore, the discovery of the person with unknown safety may be quicker.

  Although the present invention has been described in the preferred embodiments above, the present invention is not so limited. It will be understood that various other embodiments may be made without departing from the spirit of the invention. Furthermore, in this embodiment, although the effect | action and effect by the structure of this invention are described, these effect | actions and effects are examples and do not limit this invention.
