  If it is determined that the rescue is necessary because the position of the evacuation shelter 1 has changed, the control unit 201 sends the position information and the rescue request information of the evacuation shelter 1 from the communication device 206 to the in-vehicle computer 3 via the network 7. Transmit (step S112). In the in-vehicle computer 3, when the communication device 306 receives the position information and the rescue request information via the network 7 (step S113), the control unit 201 indicates the position information of the evacuation shelter 1 and the rescue request information. The contents are displayed on the output device 305. The rescuer who performs the rescue activity looks at the screen displayed on the output device 305 and performs the activity to rescue the evacuation shelter 1.

  Through the processing as described above, the host computer 2 monitors the position information transmitted from the evacuation shelter 1 installed in the building 8, and makes a rescue request to the in-vehicle computer 3 when the position information changes. Send information that instructs Next, details of processing performed in the host computer 2 and the evacuation shelter 1 will be described with reference to FIGS. 8 and 9.

  FIG. 8 is a flowchart showing details of processing in the host computer 2. The control unit 201 of the host computer 2 determines whether a command input by operating the input device 204 or a command received from the communication device 206 has been received (step S201). ). If no command is received, the process of step S201 is repeated. When any command is received, the control unit 201 determines what type of the received command is (step S202).

  If the received command indicates registration, the control unit 201 issues a shelter ID that uniquely identifies the evacuation shelter 1 to be registered (step S203). Then, the control unit 201 determines whether to make a evacuation request to the residents of the evacuation shelter 1 according to the location conditions such as the evacuation shelter 1 being near a river or facing a cliff. An evacuation request criterion that serves as a criterion to perform is calculated (step S204).

  Then, the control unit 201 registers the shelter ID, the position information (initial position) of the evacuation shelter 1, the evacuation request criterion, the information (address) as the contact information, and the like in the evacuation shelter database of the HDD 202. (Step S205). Then, the process returns to step S201.

  If the received command is the weather information received from the weather computer 4 via the dedicated line 6, the control unit 201 analyzes the weather information (step S206). Then, it is determined whether the evacuation shelter 1 whose weather information analysis result exceeds the evacuation request criterion calculated in step S204 is registered in the evacuation shelter database (step S207).

  If the evacuation shelter 1 exceeding the evacuation request standard is registered in the evacuation shelter database of the HDD 202, the control unit 201 determines whether the evacuation shelter 1 is in the pre-monitoring mode or the monitoring mode (step S208). If the evacuation shelter 1 is not in the pre-monitoring mode or the monitoring mode, the control unit 201 registers evacuation information for requesting evacuation to the evacuation shelter 1 from the communication device 206 to the evacuation shelter database of the HDD 202 via the network 7. It transmits to the address of the evacuated shelter 1 that has been made (step S209).

  Then, the control unit 201 sets the evacuation shelter 1 to the pre-monitoring mode. In the pre-monitor mode, the control unit 201 monitors reception of evacuation start information transmitted from the evacuation shelter 1 via the network 7 (step S210). Then, the process returns to step S201.

  When it is determined in step S207 that the evacuation shelter 1 exceeding the evacuation request standard is not registered in the evacuation shelter database of the HDD 202, and when it is determined in step S208 that the evacuation shelter 1 is in the pre-monitoring mode or the monitoring mode. Returns to the process of step S201.

  If the received command is the shelter ID received from the evacuation shelter 1 via the network 7 and the evacuation cancellation, the control unit 201 cancels the monitoring mode or the pre-monitoring mode in the evacuation shelter 1 indicated by the shelter ID (step). S211). Then, the process returns to step S201.

  If the received command is the shelter ID received from the evacuation shelter 1 via the network 7 and the evacuation start, the control unit 201 sets the evacuation shelter 1 indicated by the shelter ID to the monitoring mode. In the monitoring mode, the control unit 201 monitors reception of position information transmitted from the evacuation shelter 1 via the network 7 (step S212). Then, the process returns to step S201.

  If the received command includes the shelter ID and position information received from the evacuation shelter 1 via the network 7, the control unit 201 sets the position of the evacuation shelter 1 indicated by the shelter ID in the evacuation shelter database of the HDD 202. It is determined whether or not the registered initial position has been changed (step S213). If the position has changed, the control unit 201 sends the position information of the evacuation shelter 1 and the rescue request information for requesting rescue to the evacuation shelter 1 from the communication device 206 to the in-vehicle computer 3 via the network 7. Transmit (step S214). The rescue request information includes the ID of the evacuation shelter 1. Then, the process returns to step S201.

  If the position of the evacuation shelter 1 has changed in step S213, the control unit 201 determines whether or not the evacuation shelter 1 has continued to be evacuated (step S215). Here, the control unit 201 needs to evacuate because the analysis result of the weather information does not exceed the evacuation request standard registered in the evacuation shelter database of the HDD 202 in the process of step S207 performed previously. It is determined that the situation has ended. If the situation requiring evacuation has been completed, the control unit 201 registers unnecessary evacuation information for prompting evacuation cancellation to the evacuation shelter 1 from the communication device 206 to the evacuation shelter database of the HDD 202 via the network 7. It is transmitted to the address of the evacuated shelter 1 (step S216). Then, the process returns to step S201.

  If the situation requiring evacuation continues, the control unit 201 registers the evacuation continuation information for urging evacuation to the evacuation shelter 1 from the communication device 206 to the evacuation shelter database of the HDD 202 via the network 7. It is transmitted to the address of the evacuated shelter 1 (step S217). Then, the process returns to step S201.

  If the received command is other, the CPU 101 executes other processing (step S218). Since this process is not directly related to the present invention, detailed description thereof is omitted. Thereafter, the process returns to step S201.

  FIG. 9 is a flowchart showing in detail the processing in the computer device in the evacuation shelter 1. The CPU 101 of the evacuation shelter 1 determines whether or not the power of the communication interface 108 is turned on and an instruction transmitted from the host computer 2 is received from the communication interface 108 via the network 7 (step S301).

  If the instruction transmitted from the host computer 2 is received, the CPU 101 determines whether the instruction is evacuation information (step S302). If the evacuation information is required, the CPU 101 turns on the power of the output unit 111 and instructs the output unit 111 to output sound, thereby outputting a sound for evacuation request from the speaker 1C (step S1). S303). Then, the process returns to step S301.

  If the instruction transmitted from the host computer 2 is not evacuation information, the CPU 101 determines whether the instruction is unnecessary evacuation information (step S304). If it is unnecessary evacuation information, the CPU 101 turns on the power of the output unit 111 and instructs the output unit 111 to output sound, thereby outputting a sound for requesting evacuation from the speaker 1C ( Step S305). Then, the process returns to step S301.

  If the instruction transmitted from the host computer 2 is not unnecessary evacuation information, the CPU 101 determines whether the instruction is evacuation continuation information (step S306). If it is evacuation continuation information, the CPU 101 turns off the power of the communication interface 108 (step S307). Then, the process returns to step S301.

  If the instruction transmitted from the host computer 2 is not evacuation continuation information, the CPU 101 executes processing according to the other instruction (step S308). This process includes the registration of a shelter ID that is performed when the host computer 2 communicates for the first time after registration with the disaster prevention system, but is not directly related to the present invention. Is omitted. Thereafter, the process returns to step S301.

  In the process of step S301, the CPU 101 is in the evacuation mode if the communication interface 108 is turned off or if there is no instruction received from the host computer 2 even if the communication interface 108 is turned on. It is determined whether or not (step S309).

  If not in the evacuation mode, the CPU 101 determines whether evacuation to the evacuation shelter 1 is started. Here, when the input unit 110 detects the evacuation start signal, the CPU 101 determines that the evacuation has started normally by turning on the power of the lock detection unit 104 and detecting the lock signal. To do. The power source of the lock detection unit 104 is switched off after detecting the lock signal. CPU 101 does not turn on the lock detection unit 104 unless it detects an evacuation start signal from the input unit 110 (step S310).

  If the evacuation has not started, the CPU 101 executes the process if there is another process to be executed (step S311). This processing includes charging of the battery 106, registration in the disaster prevention system, switching of operating power supply when the power interruption detection circuit 107 detects a voltage drop or recovery, etc., but is directly related to the present invention. Since there is no relationship, detailed description is omitted. Thereafter, the process returns to step S301.

  On the other hand, if the evacuation has started, the CPU 101 determines whether or not the evacuation request sound started in the process of step S303 is being output from the speaker 1C (step S312). If the evacuation request is being output, the key 1B of the door 1A of the evacuation shelter 1 is locked and the evacuation start button 1D is operated in accordance with the output of the sound for evacuation request. Become. In this case. The CPU 101 causes the output unit 111 to finish outputting the evacuation request sound from the speaker 1C, and turns off the power of the output unit 111 (step S313). Then, the process proceeds to step S314.

  On the other hand, if the evacuation request is not being output, the resident has voluntarily locked the key 1B of the door 1A of the evacuation shelter 1 and operated the evacuation start button 1D to start evacuation. In this case, the process proceeds to step S314 as it is.

  In step S314, the CPU 101 sets the evacuation mode. Next, the CPU 101 starts measuring the evacuation timer (step S315). After transmitting the shelter ID and the evacuation start information from the communication interface 108 to the host computer 2 via the network 7 (step S316), the CPU 101 turns off the communication interface 108 (step S317). Then, the process returns to step S301.

  If it is not in the evacuation mode in the process of step S309, the CPU 101 determines whether the power interruption detection unit 107 has detected a voltage drop or a return (step S318). When the power interruption detection circuit 107 detects a voltage drop, the CPU 101 switches the operation power supply of the evacuation shelter 1 from the external power source to the battery power source. When the power interruption detection circuit 107 detects voltage restoration, the CPU 101 switches the operating power of the evacuation shelter 1 from the battery power source to the external power source (step S319). Then, the process returns to step S301.

  On the other hand, if voltage drop or return is not detected, the CPU 101 determines whether evacuation to the evacuation shelter 1 has been released. Here, when the input unit 110 detects the evacuation release signal, the CPU 101 turns on the power of the lock detection unit 104, and the lock detection unit 104 detects the unlock signal so that the evacuation is normally released. judge. The power source of the lock detection unit 104 is switched off after detecting the unlock signal. CPU 101 does not turn on the lock detection unit 104 unless it detects an evacuation release signal from the input unit 110 (step S320).

  If the evacuation is unlocked, the CPU 101 determines whether or not an evacuation request sound is being output from the speaker 1C (step S321). If an evacuation request is being output, the evacuation release button 1E is operated in accordance with the output of an evacuation request request, and the evacuation is released by unlocking the key 1B of the door 1A of the evacuation shelter 1. It will be. In this case. The CPU 101 ends the output of the evacuation request to the output unit 11 and turns off the power of the output unit 111 (step S322). Then, the process proceeds to step S323.

  On the other hand, if the evacuation request is not being output, the evacuation release button 1E is voluntarily operated by a resident, and the evacuation is released by unlocking the key 1B of the door 1A of the evacuation shelter 1. In this case, the process proceeds to step S323 as it is.

  In step S323, the CPU 101 cancels the evacuation mode. Next, the CPU 101 finishes counting the evacuation timer (step S324). The CPU 101 turns on the power of the communication interface 108, and transmits the shelter ID and evacuation cancellation information from the communication interface 108 to the host computer 2 via the network 7 (step S325). Then, the process returns to step S301.

  If the evacuation is not unlocked in the process of step S320, the CPU 101 determines whether or not the time of the evacuation timer that has started the time measurement in the process of step S315 is 5t (step S326). If the time of the evacuation timer is not 5t, the process returns to step S301. On the other hand, if the time of the evacuation timer is 5 t, the CPU 101 activates the GPS 109 and acquires position information from the GPS satellite 5. Then, the CPU 101 turns off the power of the GPS 109 (step S327).

  Then, the CPU 101 turns on the communication interface 108 (step S328), and transmits the shelter ID, the acquired position information, and transmission request information from the communication interface 108 to the host computer 2 via the network 7 (step S328). S329). Then, the process returns to step S301.

  As described above, in the disaster prevention system according to this embodiment, the person 1 who has evacuated to the evacuation shelter 1 locks the key 1B of the door 1A and operates the evacuation start button 1D. Set to If the evacuation shelter 1 is set to the evacuation mode, the shelter ID and the evacuation start information are transmitted from the communication interface 108 to the host computer 2 via the network 7. In the host computer 2 that has received the evacuation start information, the evacuation shelter 1 indicated by the shelter ID is set to the monitoring mode. The position information of the evacuation shelter 1 is transmitted from the evacuation shelter 1 in the evacuation mode to the host computer 2, and the position information is received from the evacuation shelter 1 in the host computer 2 in the monitoring mode. A rescue request is made to the computer 3. As described above, after the evacuation to the evacuation shelter 1, the rescue is requested by changing the position information of the evacuation shelter 1. I can do it.

  The host computer 2 transmits evacuation information to the evacuation shelter 1 whose result of analyzing the weather information received from the weather computer 4 exceeds the evacuation request standard registered in the evacuation shelter database of the HDD 202. . The weather computer 4 collects weather information about weather and earthquakes in real time. Here, if the host computer 2 determines that the evacuation shelter 1 is in the evacuation required state, the evacuation information is transmitted from the host computer 2 to the evacuation shelter 1 and the pre-monitor mode is set. In the host computer 2 in the pre-monitoring mode, reception of the evacuation start information transmitted from the evacuation shelter 1 is monitored. In this case, the safety of the resident can be grasped by monitoring whether or not evacuation is started in the evacuation shelter 1 that is in an evacuation required state.

  Further, when the evacuation shelter 1 receives the evacuation information transmitted from the host computer 2 from the communication interface 108 via the network 7, an evacuation request sound is output from the speaker 1 </ b> C of the evacuation shelter 1. In the building 8 where the evacuation shelter 1 is installed, it is notified that evacuation is necessary. Here, in the evacuation shelter 1 in an evacuation required state, an evacuation request is output to a resident who lives in the building 8. In this case, the resident knows that the evacuation is necessary by receiving the output of the evacuation request, and can secure safety by evacuating to the evacuation shelter 1.

  After that, when the evacuation shelter 1 receives unnecessary evacuation information transmitted from the host computer 2 from the communication interface 108 via the network 7, a sound for requesting evacuation is output from the speaker 1C of the evacuation shelter 1. Thus, it is notified that evacuation is no longer necessary in the building 8 where the evacuation shelter 1 is installed. Here, in the evacuation shelter 1 in which the evacuation-necessary state is released, the evacuation unnecessary information is output to the residents living in the building 8. In this case, the resident can know whether the evacuation is no longer necessary by outputting the evacuation unnecessary information. Therefore, the evacuation is unnecessary by releasing the evacuation to the evacuation shelter 1 after the evacuation is no longer necessary. There is no need to continue.

  By the way, when the evacuation shelter 1 is set to the evacuation mode, the communication interface 108 of the evacuation shelter 1 is turned off. In the evacuation shelter 1 in the evacuation mode, every time the evacuation timer becomes 5t, the communication interface 108 is turned on, and transmission request information for requesting reception of information on whether or not the evacuation warning is released is sent, The data is transmitted from the communication interface 108 to the host computer 2 via the network 7. Here, when the host computer 2 receives the transmission request information from the evacuation shelter 1, the evacuation status is canceled if the evacuation required state is canceled, and the evacuation continuation information if the evacuation is ongoing, respectively. Sent to evacuation shelter 1 In this case, the evacuation shelter 1 may receive unnecessary evacuation information or evacuation continuation information from the communication interface 108 at a predetermined interval from the transmission of the transmission request information, and the burden on communication can be reduced. The communication interface 108 is turned off after transmitting the transmission request information. In this case, power can be saved in the evacuation shelter 1 by switching the power supply in the communication interface 108 between on and off.

  By the way, in the evacuation shelter 1 in the evacuation mode, the power supply of the GPS 109 is turned on every time the evacuation timer becomes 5t, and is turned off after receiving the position information from the GPS satellite 5. The power source of the lock detection unit 104 is turned on when an evacuation start signal or evacuation release signal is received from the input unit 110, and is turned off after outputting the lock signal or the unlock signal to the CPU 101. The power source of the output unit 111 is turned on when the evacuation information or unnecessary evacuation information is received from the host computer 2, and is turned off when the start or release of evacuation is detected. As described above, in the computer device mounted on the evacuation shelter 1, the power can be saved in the evacuation shelter 1 by switching the power on and off.

  By the way, when the position of the evacuation shelter 1 is changed in the host computer 2 in the monitoring mode, the position information of the evacuation shelter 1 and the alarm information are sent from the host computer 2 to the in-vehicle computer 3 of the rescuer who performs the rescue operation. And are sent. Since the in-vehicle computer 3 is a device provided in the vehicle of the rescuer who performs the rescue activity, the rescuer can move to the rescue location more quickly and perform the rescue activity.

  When the door 1A of the evacuation shelter 1 is opened by a normal operation before receiving unnecessary evacuation information from the host computer 2, the evacuation mode of the evacuation shelter 1 is canceled, and the evacuation cancellation information is stored in the network 7 Via the communication interface 108 to the host computer 2. In the host computer 2 that has received the evacuation cancellation information, the monitoring mode is cancelled. In this case, when the evacuation shelter 1 is canceled by the resident's voluntary judgment, the host computer 2 can grasp the fact. After that, when the evacuation state is still continued after the evacuation is canceled, the evacuation shelter 1 receives the evacuation information transmitted from the host computer 2 again. Then, the evacuation shelter 1 outputs an evacuation request from the speaker 1C, and the residents of the building 8 where the evacuation shelter 1 is installed can recognize again that evacuation is necessary.

  By the way, when the power supply from the external power source to the evacuation shelter 1 is interrupted, the operating power of the evacuation shelter 1 is switched to the supply from the battery power source. In this case, power is supplied to the evacuation shelter 1 even when a power failure occurs or the evacuation shelter 1 is swept away by a debris flow or the like, and the host computer 2 grasps the position information of the evacuation shelter 1. It is possible to ensure the safety of those who have evacuated.

  By the way, when the evacuation shelter 1 registers with the disaster prevention system, the host computer 2 issues a shelter ID that uniquely identifies the evacuation shelter 1. The information transmitted from the evacuation shelter 1 to the host computer 2 always includes the shelter ID. Here, each of the plurality of evacuation shelters 1 registered in the disaster prevention system has a shelter ID, so that the host computer 2 can identify which evacuation shelter 1 is information and perform processing. Become.

  The present invention is not limited to the above-described embodiment, and various modifications and applications are possible. Hereinafter, modifications of the above-described embodiment applicable to the present invention will be described.

  In the above embodiment, the evacuation request criteria of each evacuation shelter 1 is calculated by the control unit 201 in the processing of step S204 in the host computer 2, and the calculated evacuation request criteria correspond to the evacuation shelter 1 Although it was supposed to be registered in the shelter database, it is not limited to this. The evacuation request criteria of each evacuation shelter 1 is set by input from the input device 204 of the host computer 2, and the set evacuation request criteria are registered in the evacuation shelter database corresponding to the evacuation shelter 1. There may be. In addition, if a common evacuation request standard is used for all evacuation shelters 1, it is not necessary to register in the evacuation shelter database. For example, it is sufficient that the corresponding standard is determined in the determination step in the program. .

  In the above embodiment, the evacuation request standard is treated as one standard, but the evacuation request standard may be composed of a plurality of standards. For example, the evacuation request standard may include a unit time standard, which is a standard for precipitation per hour, and a total precipitation, which is a standard for precipitation from the beginning of falling. Moreover, the evacuation request | requirement reference | standard which takes a different value with the evacuation shelter 1 and the evacuation request | requirement reference | standard which becomes the same value in any evacuation shelter 1 may be included. In these cases, the host computer 2 may include information indicating whether an evacuation is necessary due to what kind of event is included in the evacuation required information and transmit the information to the evacuation shelter 1. The evacuation shelter 1 may output information indicating whether an evacuation is necessary due to what kind of event when outputting the evacuation request. Here, the resident can know by what kind of event the evacuation is necessary by receiving the output of the evacuation request, and can secure safety by evacuating to the evacuation shelter 1.

  In the above embodiment, in the process of step S215, the control unit 201 determines whether or not the situation requiring evacuation is continuing. In the previously performed process of step S207, the analysis result of the weather information is stored in the HDD 202. How to determine whether a situation requiring evacuation has been completed because the evacuation request criteria registered in the evacuation shelter database are no longer exceeded. Is not limited to this. It may be determined by a method similar to the evacuation request standard described above (registered in the evacuation shelter database, input from the input device 204 of the host computer 2, etc.). Further, the evacuation request standard and the standard for determining whether or not the situation requiring evacuation continues does not necessarily have to be determined by the same method.

  In the above embodiment, the evacuation request sound or the evacuation non-request sound is output from the speaker 1C to notify the resident that the evacuation is necessary or no longer necessary, The notification method is not limited to this. For example, it may be provided with a device that notifies by sound such as a bell or buzzer or light such as a lamp. Alternatively, an address such as a mobile phone may be registered in the evacuation shelter database, and notification may be made by sending an email to the address. Alternatively, some of them may be included.

  In the above embodiment, whether the sound for requesting refuge or not requesting evacuation is output from the speaker 1C of the evacuation shelter 1 depends on the instruction received from the host computer 2 (required evacuation information, unnecessary evacuation information). However, the present invention is not limited to this, and includes a device that determines whether to output an evacuation request sound or an evacuation request request sound to the evacuation shelter 1, and according to the determination of the device. A sound for evacuation request or evacuation non-request may be output.

  For example, when the evacuation shelter 1 is provided with a seismic motion device, the evacuation request sound may be output when the initial tremor is detected by the seismic motion device. In this case, evacuation to the evacuation shelter 1 can be promoted before the mainshock even for disasters such as earthquakes that are difficult to leave, and the safety of residents can be ensured.

  For example, when the evacuation shelter 1 includes a smoke detection device, the smoke detection device detects that a large amount of smoke has been generated in the building 8 where the evacuation shelter 1 is installed. May be output. Further, when the evacuation shelter 1 is provided with a temperature detection device, the evacuation shelter 1 is output when the temperature detection device detects that the temperature around the evacuation shelter 1 has become a predetermined value or less. It is good. In this case, evacuation to the evacuation shelter 1 can be promoted even in the case of a fire, and the safety of residents can be ensured.

  In addition, it is preferable that the apparatus which determines whether the sound for evacuation request | requirement or the evacuation request | requirement sound is output is a structure where a power supply switches on and off at predetermined timing. Moreover, it is preferable that the evacuation shelter 1 includes information indicating whether the evacuation is started by any event, and transmits the information to the host computer 2 together with the evacuation start information.

  In the above embodiment, the host computer 2 determines whether the position information of the evacuation shelter 1 has changed. However, the present invention is not limited to this. For example, in the process of step S327 performed in the evacuation shelter 1, it is determined whether or not the position has changed when the GPS 109 is activated and the position information is acquired. Only when the position has changed, the position information is stored in the host computer 2 It is good also as what is transmitted to. Here, the position information is transmitted from the evacuation shelter 1 to the host computer 2 only when the position of the evacuation shelter 1 changes from the normal time, thereby reducing the communication burden on the evacuation shelter 1 and the host computer 2. be able to. In the evacuation shelter 1, power can be saved.

  In the above embodiment, when the time of the evacuation timer is 5t, after the CPU 101 activates the GPS 109 and acquires the position information in the processing of step S327 to step S329, the control unit 201 supplies power to the communication interface 108. Is turned on, and the shelter ID, the acquired location information, and the transmission request information are transmitted from the communication interface 108 to the host computer 2 via the network 7, but the timing for performing the processing of step S327 to step S329 is as follows. However, this is not a limitation. For example, as the time elapses from the start of evacuation, the timing interval for performing the processing of steps S327 to S329 may be shortened. In this case, as the evacuation state continues, the need for rescue generally increases, so the time interval for transmitting the location information is shortened as time elapses from the start of evacuation, so that alarms can be made smoothly. The safety of residents who have evacuated to the evacuation shelter 1 can be ensured.

  In the above embodiment, the position information and the transmission request information are transmitted to the host computer 2 at the same timing in the processing of step S329. However, the timing of transmitting the position information and the transmission request information is different. May be. For example, the time interval for transmitting the position information may be longer than the time interval for transmitting the transmission request information.

  In the above embodiment, in the process of step S329, the control unit 201 turns on the power of the communication interface 108, and obtains the shelter ID, the acquired position information, and transmission request information from the communication interface 108 via the network 7. Although the information is transmitted to the host computer 2, the information to be transmitted is not limited to this, and may include other information. For example, information indicating whether or not the power source is switched to the supply from the battery 106 may be included, and the host computer 2 may monitor whether or not electric power can be supplied to the evacuation shelter 1 in the elapsed time from there. Moreover, the time information of an evacuation timer may be included. In this case, if the time measured by the evacuation timer exceeds a predetermined time, the host computer 2 can make a rescue request.

  Furthermore, you may provide the detection apparatus which adds the information to transmit. For example, when the evacuation shelter 1 includes a collapse detection unit that determines whether or not the building 8 in which the evacuation shelter 1 is installed collapses, when the building 8 collapses, the evacuation shelter 1 Collapse information is transmitted to the host computer 2. In this case, the host computer 2 can ensure the safety of the evacuated residents to the evacuation shelter 1 by grasping the collapse of the building 8 by receiving the collapse information. Note that the detection device that adds the information to be transmitted preferably has a structure in which the power is switched on and off at a predetermined timing.

  In the above embodiment, the CPU 101 is configured to turn off the communication interface 108 by receiving the evacuation continuation information. However, the condition for turning off the communication interface 108 is not limited to this. For example, in the process of step S329, it is necessary to receive unnecessary evacuation information from the time counted by the evacuation timer when transmission request information is transmitted from the communication interface 108 to the host computer 2 via the network 7. The power supply of the communication interface 108 may be turned off when a sufficiently long predetermined time has elapsed. In this case, if the evacuation shelter 1 does not receive unnecessary evacuation information within a predetermined time, the communication interface 108 is powered off. Here, the host computer 2 does not need to transmit evacuation continuation information, and the evacuation shelter 1 can suppress power consumption for receiving the continuation evacuation information.

  In the above embodiment, the evacuation shelter 1 turns on the power of the output unit 111 in the process of step S303 or the process of step S305, and instructs the output unit 111 to output sound, thereby 1C outputs an evacuation request sound or an evacuation request sound, and when evacuation is started or evacuation is released, the output of the evacuation request and evacuation request not required is completed in the process of step S313 or the process of step S322. However, the timing of the end of the output of the evacuation request and the evacuation request request is not limited to this. For example, the timing of the internal timer may be started when outputting the evacuation request and the evacuation request, and the output of the evacuation request and the evacuation request may be terminated when the internal timer times a predetermined time. Here, information indicating that evacuation start and evacuation cancellation were not performed may be transmitted to the host computer 2.
