Each of the three target areas A13 is also referred to as "target area A1".

  By the way, as mentioned above, the conventional electric power interruption system can interrupt only the electric path of the building (management area) in which the gas meter and the electric breaker are installed. Therefore, when it is intended to shut off the electrical paths of a plurality of control areas included in the target area, the gas meter and the electric breaker must be installed in all the control areas, and there is a problem that the cost of the entire system increases. The

  The disaster detection system 1, the transmitting device 2, the receiving device 3, and the power shutoff system 10 according to the present embodiment shut off the second electric path E2 in the second management area D2 while suppressing the cost increase of the entire system.

Then, the detection unit 21 detects an earthquake motion caused by an earthquake, and outputs a voltage signal of a voltage value corresponding to the magnitude of the earthquake motion to the control unit 24.

  The communication unit 22 is a communication interface for communicating with the reception side device 3 (communication unit 31). The communication unit 22 is configured to perform wireless communication with the reception side device 3 (communication unit 31). The wireless communication between the communication unit 22 and the reception side device 3 (the communication unit 31) is, for example, a specific small power wireless communication which does not require a license using radio waves of 920 MHz band. The communication unit 22 further includes a transmission unit 221 for transmitting the communication signal S3. In the present embodiment, the transmission unit 221 is configured to transmit the communication signal S3 by broadcast. Here, “broadcast” refers to transmitting a communication signal without specifying a transmission destination of the communication signal. In this case, it is determined whether or not the communication signal is to be received at the communication signal receiving side (the receiving side device 3 in the present embodiment).

  The communication signal S3 is a signal for transmitting the detection result of the detection unit 21 to the reception side device 3 included in the target area described later. The communication signal S3 includes the detection result of the detection unit 21 and area information (additional information).

In other words, the first output unit 23 is configured to output the first cutoff signal S1 based on the detection result of the detection unit 21. The first blocking signal S1 is a signal for blocking the first electric path E1 in the first management area D1. The first shutoff unit 41 shuts off the first electric path E1 by opening the contact 411 in accordance with the first shutoff signal S1 from the first output unit 23.

  The control unit 24 is configured by a microcomputer having a processor and a memory. That is, the control unit 24 is realized by a computer system having a processor and a memory. The computer system functions as the control unit 24 by the processor executing an appropriate program. The program may be pre-recorded in a memory, or may be provided through a telecommunication line such as the Internet or in a non-transitory recording medium such as a memory card.

  The control unit 24 is configured to determine the magnitude of the earthquake motion caused by the earthquake based on the detection result of the detection unit 21. Then, the control unit 24 determines that the first electric path E1 in the first management area D1 should be cut off, and cuts off the first electric path E1, if the magnitude of the earthquake motion is equal to or greater than a threshold (for example, seismic intensity 5). The control signal of is output to the first output unit 23. The first output unit 23 outputs the first shutoff signal S1 to the first shutoff unit 41 in accordance with the control signal from the control unit 24.

  Further, the control unit 24 includes an adjustment unit 241. The adjustment unit 241 is configured to adjust an area to which the communication signal S3 should be transmitted (hereinafter, also referred to as “target area”) based on the disaster related information. In other words, the adjustment unit 241 adjusts the transmission destination of the communication signal S3 based on the disaster related information. The "disaster related information" mentioned here is information for specifying the range affected by the disaster, and is, for example, an earthquake map issued from a local government etc. when the disaster is an earthquake. Then, based on the earthquake map, the adjustment unit 241 sets (adjusts) the transmission destination of the area communication signal S3 in which the earthquake whose magnitude is equal to or greater than the threshold is occurring. In the present embodiment, as an example, the adjustment unit 241 (control unit 24) acquires disaster related information from a server device such as a local government via the communication unit 22.

(2.2) Receiving-Side Device Next, the configuration of the receiving-side device 3 will be described. As shown in FIG. 1, the reception side device 3 includes a communication unit 31, a second output unit 32, and a control unit 33.

  The communication unit 31 is a communication interface for communicating with the communication unit 22 of the transmission side device 2. The communication unit 31 is configured to perform wireless communication with the communication unit 22. The wireless communication between the communication unit 31 and the communication unit 22 is, for example, specific low power wireless communication using radio waves of 920 MHz band. The communication unit 31 has a receiving unit 311 for receiving the communication signal S3.

  The second output unit 32 is configured to output a second cutoff signal S2 to a second cutoff unit 71 (to be described later) in accordance with a control signal (to be described later) output from the control unit 33. In other words, the second output unit 32 is configured to output the second cutoff signal S2 based on the detection result of the detection unit 21 included in the communication signal S3. The second cutoff signal S2 is a signal for blocking the second electric path E2 in the second management area D2. The second shutoff unit 71 shuts off the second electric path E2 by opening the contact 711 in accordance with the second shutoff signal S2 from the second output unit 32.

  The control unit 33 is configured by a microcomputer having a processor and a memory. That is, the control unit 33 is realized by a computer system having a processor and a memory. The computer system functions as the control unit 33 by the processor executing an appropriate program. The program may be pre-recorded in a memory, or may be provided through a telecommunication line such as the Internet or in a non-transitory recording medium such as a memory card. In the memory of the control unit 33, position information (for example, an address or the like) of the reception side device 3 is recorded in advance.

  The control unit 33 is configured to determine the magnitude of the earthquake motion caused by the earthquake based on the detection result of the detection unit 21 included in the communication signal S3 received by the reception unit 311. Then, the control unit 33 determines that the second electric path E2 in the second management area D2 should be cut off if the magnitude of the earthquake motion is equal to or greater than a threshold (for example, seismic intensity 5), and cuts off the second electric path E1. The control signal of is output to the second output unit 32. The second output unit 32 outputs the second cutoff signal S2 to the second cutoff unit 71 in accordance with the control signal from the control unit 33. Here, it is preferable that the threshold value for comparing with the magnitude of the earthquake motion that is the detection result of the detection unit 21 be configured to be individually set by the transmission side device 2 and the reception side device 3.

  In addition, the control unit 33 includes a processing unit 331. The processing unit 331 performs processing for specifying the transmission destination of the communication signal S3. In the present embodiment, as an example, the processing unit 331 determines whether or not the target area is included based on the area information included in the communication signal S3 received by the receiving unit 311 and the position information of the own unit, If the self is included, it is determined (specified) that the signal is addressed to the self. Then, the control unit 33 acquires the detection result of the detection unit 21 included in the communication signal S3 if it is the communication signal S3 addressed to itself, and discards the communication signal S3 if it is not the communication signal S3 addressed to itself.

(2.3) First Shielding Unit and Second Shielding Unit Next, configurations of the first shielding unit 41 and the second shielding unit 71 will be described.

  The 1st interruption | blocking part 41 has the contact 411 inserted in the 1st electric path E1 which forms the feed path from the system power supply 5 to load, as shown in FIG. The first blocking portion 41 is accommodated in the distribution board 4 of the first management area (a detached house) D1. The first shutoff unit 41 shuts off the first electric path E1 by opening the contact 411 in accordance with the first shutoff signal S1 from the first output unit 23 of the transmission side device 2.

  The 2nd interruption | blocking part 71 has the contact point 711 inserted in 2nd electric path E2 which forms the feed path from system power supply 5 to load, as shown in FIG. The second blocking portion 71 is housed in the distribution board 7 of the second management area (a detached house) D2. The second shutoff unit 71 shuts off the second electric path E2 by opening the contact 711 in accordance with the second shutoff signal S2 from the second output unit 32 of the reception device 3.

(3) Operation Next, operations of the disaster detection system 1 and the power shutoff system 10 according to the present embodiment will be described with reference to FIGS. 3 and 4.

(3.1) First Operation Example First, a first operation example of the disaster detection system 1 and the power shutoff system 10 will be described with reference to FIG. In the following description, it is assumed that an earthquake having a seismic intensity of 5 or more occurs in the first target area A11. In addition, since the same operation is performed in the second target area A12 and the third target area A13, the description is omitted here.

  The control unit 24 of the transmission side device 2 determines from the detection result of the detection unit 21 that an earthquake has occurred if the magnitude of the earthquake motion is equal to or greater than a threshold (for example, seismic intensity 5) (Yes in step ST1). The control unit 24 creates a communication signal S3 including the detection result of the detection unit 21, and causes the transmission unit 221 to transmit the created communication signal S3 by broadcast (step ST2). At this time, the adjustment unit 241 of the control unit 24 sets (adjusts) an area (target area) to which the communication signal S3 should be transmitted based on the disaster related information related to the earthquake.

  Further, the control unit 24 outputs a control signal for interrupting the first electric path E1 to the first output unit 23 because an earthquake whose magnitude of the earthquake motion is equal to or larger than the threshold value is generated. The first output unit 23 outputs the first shutoff signal S1 to the first shutoff unit 41 in accordance with the control signal from the control unit 24. Then, the first shutoff unit 41 shuts off the first electrical path E1 in accordance with the first shutoff signal S1 from the first output unit 23 (step ST3).

  On the other hand, since the detection unit is not provided in the reception side device 3, the control unit 33 does not detect the occurrence of an earthquake (No in step ST1). In this case, the control unit 33 determines whether the receiving unit 311 has received the communication signal S3 from the transmission side device 2 (step ST4). If the reception unit 311 receives the communication signal S3 (Yes in step ST4), the control unit 33 determines whether the condition for acquiring the detection result of the detection unit 21 included in the communication signal S3 is satisfied. It determines (step ST5). Here, “condition” means that the reception side device 3 is included in the target area adjusted by the adjustment unit 241.

  If the above conditions are satisfied (Yes in step ST5), the control unit 33 acquires the detection result of the detection unit 21 included in the communication signal S3 and causes the communication unit 31 to transmit the communication signal S3 by broadcast ( Step ST2). Here, it is preferable that the number of hops be set so as to limit the retransmission of the communication signal S3.

  Further, the control unit 33 determines whether or not the magnitude of the earthquake motion is equal to or more than the threshold value based on the detection result of the detection unit 21. If the magnitude of the earthquake motion is equal to or more than the threshold value, control for interrupting the second electric path E2 The signal is output to the second output unit 32. The second output unit 32 outputs the second shutoff signal S2 to the second shutoff unit 71 in accordance with the control signal from the control unit 33. Then, the second shutoff unit 71 shuts off the second electric path E2 in accordance with the second shutoff signal S2 from the second output unit 32 (step ST3).

  The control unit 33 ends the operation when the reception unit 311 does not receive the communication signal S3 (No in step ST4) or when the above condition is not satisfied (No in step ST5). Thereafter, the disaster detection system 1 and the power shutoff system 10 periodically execute the operations of the above-described steps ST1 to ST5.

(3.2) Second Operation Example Next, a second operation example of the disaster detection system 1 and the power shutoff system 10 will be described with reference to FIG. In the following description, it is assumed that the receiving device 3A is included in the target area adjusted by the adjusting unit 241 and the receiving device 3B is not included in the target area.

  The control unit 24 of the transmission side device 2A detects the occurrence of an earthquake from the detection result of the detection unit 21 (step ST11). The control unit 24 creates a communication signal S3 including the detection result of the detection unit 21 and causes the transmission unit 221 to transmit the created communication signal S3 by broadcast (step ST12). At this time, the adjustment unit 241 of the control unit 245 sets (adjusts) an area (target area) to which the communication signal S3 should be transmitted based on the disaster related information related to the earthquake.

  Further, the control unit 24 outputs a control signal for interrupting the first electric path E1 to the first output unit 23 because the magnitude of the earthquake motion is equal to or greater than a threshold (for example, the seismic intensity 5). The first output unit 23 outputs the first shutoff signal S1 to the first shutoff unit 41 in accordance with the control signal from the control unit 24. Then, the first shutoff unit 41 shuts off the first electrical path E1 in accordance with the first shutoff signal S1 from the first output unit 23 (step ST13). On the other hand, since the detection units are not provided in the reception side devices 3A and 3B, the control unit 33 of the reception side devices 3A and 3B does not detect the occurrence of the earthquake.

  When receiving the communication signal S3 from the transmission side device 2A, the control unit 33 of the reception side device 3A determines whether the above condition is satisfied. Here, since the reception side device 3A is included in the target area adjusted by the adjustment unit 241, the control unit 33 acquires the detection result of the detection unit 21 included in the communication signal S3. Further, the control unit 33 causes the communication unit 31 to transmit the communication signal S3 by broadcast (step ST14).

  Here, since the transmission side device 2A is the transmission source of the communication signal S3, the transmission side device 2A discards the communication signal S3 from the reception side device 3A. Further, since the reception side device 3B is not included in the target area adjusted by the adjustment unit 241, the reception side device 3B discards the communication signal S3 from the reception side device 3A.

  The control unit 33 of the reception side device 3A determines from the detection result of the detection unit 21 included in the communication signal S3 that the magnitude of the earthquake motion due to the earthquake is equal to or greater than the threshold value. 2 Output to the output unit 32. The second output unit 32 outputs the second shutoff signal S2 to the second shutoff unit 71 in accordance with the control signal from the control unit 33. Then, the second shutoff unit 71 shuts off the second electric path E2 in accordance with the second shutoff signal S2 from the second output unit 32 (step ST15).

(4) Disaster detection method Even if it does not use the exclusive transmission side device 2 and the reception side device 3 by adopting the following disaster detection methods, for example, a portable information terminal such as a tablet terminal or a smartphone, a personal computer, etc. The same function as that of the disaster detection system 1 according to the present embodiment can be realized using

  That is, the disaster detection method includes a detection step, a transmission step, a first output step, a reception step, a second output step, and an adjustment step. The detection step is a step of detecting a disaster occurring in the first management area D1 in the target area A1 including at least one first management area D1 and at least one second management area D2. The transmission step is a step of transmitting a communication signal S3 including the detection result of the detection step. The first output step is a step of outputting a first blocking signal S1 for blocking the first electric path E1 in the first management area D1 based on the detection result of the detecting step. The receiving step is a step of receiving the communication signal S3 transmitted in the transmitting step. The second output step outputs a second cutoff signal S2 for blocking the second electric path E2 in the second management area D2 based on the detection result of the detection step included in the communication signal S3 received in the reception step. It is a step.

  According to this disaster detection method, it is possible to realize the same function as the disaster detection system 1 according to the present embodiment without using the dedicated transmission side device 2 and the reception side device 3, and in the target area A1 when a disaster occurs. The second electric path E2 in the included second management area D2 can also be cut off.

(5.1) First Modification In the embodiment described above, the case where the transmission side device 2 and the reception side device 3 directly communicate is described as an example, but as shown in FIG. The receiving device 3 may be configured to communicate via the server device 6. Hereinafter, a first modification of the disaster detection system 1 and the power shutoff system 10 will be described with reference to FIG.

  The disaster detection system 1 which concerns on a 1st modification is provided with the transmission side apparatus 2 and the receiving side apparatus 3, as shown in FIG. The transmission side device 2 includes a detection unit 21, a communication unit 22, a first output unit 23, and a control unit 24. The reception side device 3 further includes a communication unit 31, a second output unit 32, and a control unit 33. In addition, since it is the structure similar to the above-mentioned embodiment except the point in which the adjustment part 611 is provided in the server apparatus 6, detailed description is abbreviate | omitted here.

  As illustrated in FIG. 5, the server device 6 includes a control unit 61, a communication unit 62, and a storage unit 63.

  The control unit 61 is configured by a microcomputer having a processor and a memory. That is, the control unit 61 is realized by a computer system having a processor and a memory. The computer system functions as the control unit 61 by the processor executing an appropriate program. The program may be pre-recorded in a memory, or may be provided through a telecommunication line such as the Internet or in a non-transitory recording medium such as a memory card.

  The control unit 61 includes an adjustment unit 611. The adjustment unit 611 is configured to adjust the transmission destination of the communication signal S3 from the transmission side device 2 based on the above-described disaster related information. In other words, the adjustment unit 611 adjusts the area (target area) to which the communication signal S3 should be transmitted based on the disaster related information. For example, the adjustment unit 611 specifies, from the earthquake map, an area where an earthquake having a magnitude of the earthquake motion equal to or larger than the threshold has occurred, and sets (adjusts) this area as a target area.

  The communication unit 62 is a communication interface for communicating with the communication unit 22 of the transmission device 2 and the communication unit 31 of the reception device 3. The communication unit 62 is configured to perform wireless communication with the communication units 22 and 31. The wireless communication between the communication unit 62 and the communication units 22 and 31 is, for example, specified low power wireless communication using radio waves in the 920 MHz band. The communication unit 62 receives a communication signal S3 including the detection result of the detection unit 21 from the communication unit 22 (transmission unit 221). Further, the communication unit 62 adds the area information on the target area adjusted by the adjustment unit 611 to the communication signal S3 and transmits the communication signal S3 to the receiving device 3.

  The storage unit 63 is configured of a readable and writable memory. The storage unit 63 is, for example, a flash memory. Further, the storage unit 63 links and stores a plurality of disasters and a plurality of disaster related information.

  The operations of the disaster detection system 1 and the power cut-off system 10 are the same as those of the above-described embodiment except that the communication signal S3 is transmitted through the server device 6, so here the disaster detection system 1 and the power The description of the operation of the shutoff system 10 is omitted.

  In the first modification, when the control unit 24 of the transmission side device 2 determines from the detection result of the detection unit 21 that an earthquake having a magnitude of the earthquake motion equal to or larger than the threshold has occurred, a communication signal including the detection result of the detection unit 21 It is only necessary to transmit S3 to the server device 6. In other words, the control unit 24 does not have to adjust the target area to which the communication signal S3 is to be transmitted, and the processing load on the control unit 24 can be reduced as compared with the case where the target area is adjusted.

(5.2) Second Modification In the above-described embodiment and the first modification, the entire target area adjusted by the adjustment unit is set as the transmission destination of the communication signal S3, but a part of the target area is the communication signal It may be configured to be set as the transmission destination of S3. Hereinafter, a second modification of the disaster detection system 1 will be described with reference to FIG.

  The transmission side device 3 according to the second modification includes, as shown in FIG. 6, a detection unit 21, a communication unit 22, a first output unit 23, a control unit 24, and a setting unit 25. . The detection unit 21, the communication unit 22, the first output unit 23, and the control unit 24 are the same as those in the above-described embodiment, and the detailed description thereof is omitted here.

  The setting unit 25 is configured to set a part of the target area adjusted by the adjustment unit 241 of the control unit 24 as a transmission destination of the communication signal S3. Specifically, the setting unit 25 sets the receiving device 3 corresponding to the input position information as the transmission destination of the communication signal S3 by inputting the position information such as an address, for example. That is, it is possible to exclude the receiving device 3 other than the receiving device 3 set by the setting unit 25 from the transmission destination of the communication signal S3.

  According to this configuration, for example, only the relatives included in the target area can be set as the transmission destination of the communication signal S3. Therefore, even if the second electric path E2 is interrupted due to a malfunction or the like, it is difficult to cause a problem. There is an advantage.

(5.3) Other Modifications In the embodiment described above, the case where the target area A1 is a local public entity such as a municipality, and each of a plurality of management areas D1 and D2 is a single-family house included in the target area A1 It has been described as an example. On the other hand, for example, the target area A1 may be a collective housing such as an apartment, and each of the plurality of management areas D1 and D2 may be each dwelling unit of the collective housing. Furthermore, as long as the target area includes a plurality of management areas, a configuration other than the above may be used.

  In the above-described embodiment, the second output unit 32 of the reception side device 3 outputs the second cutoff signal S2 based on the detection result of one detection unit 21 from one transmission side device 2 as an example. did. On the other hand, the second output unit 32 may be configured to output the second cutoff signal S2 based on the detection results of the plurality of detection units 21 from the plurality of transmission side devices 2. In other words, the second output unit 32 is configured to output the second cutoff signal S2 when the reception unit 311 receives the plurality of communication signals S3 from the plurality of transmission side devices 2 in a predetermined period. It is also good. According to this configuration, it is possible to reduce malfunction as compared to the case where the second cutoff signal S2 is output based on the detection result of one detection unit 21.

  In addition, the second output unit 32 may be configured to output the second cutoff signal S2 when the detection result of the detection unit 21 is acquired a plurality of times. In other words, the second output unit 32 may be configured to output the second cutoff signal S2 when the receiving unit 311 receives the communication signal S3 multiple times in a predetermined period. In this case, the detection result of the detection unit 21 may be received a plurality of times from one transmission side device 2, or the detection result of the detection portion 21 may be received a plurality of times from two or more transmission side devices 2. According to this configuration, it is possible to reduce malfunction as compared to the case where the second cutoff signal S2 is output based on the detection result of one detection unit 21.

  Although the above embodiment has been described by way of example in which the transmitting unit 221 transmits the communication signal S3 every time the detecting unit 21 detects an earthquake, the transmitting unit 221 transmits the communication signal S3 with a certain probability. May be configured. In other words, the transmission unit 221 may be configured to transmit a part of detection results of the detection unit 21 instead of transmitting all the detection results. For example, when an earthquake occurs across a plurality of adjacent target areas A1, communication signals S3 are transmitted and received between the transmitting device 2 and the receiving device 3 in each of the target areas A1. May become congested. In this case, by configuring the transmission unit 221 to transmit the communication signal S3 with a certain probability, congestion of the network due to flooding can be reduced.

  In the above embodiment, the additional information (area information) for specifying the transmission destination of the communication signal S3 has been described as an example of the address, but the additional information is not limited to the address, and the postal code and the area code , GPS information, etc., or position information specified by triangulation.

According to these configurations, the area for transmitting the communication signal S3 can be specified in advance.

  Although the above-mentioned embodiment explained the case where additional information for specifying the transmitting place of communication signal S3 was contained in communication signal S3 as an example, additional information may be omitted. In other words, the processing unit 331 may be configured to specify the transmission destination of the communication signal S3 according to the communication status between the transmission unit 221 and the reception unit 311. When wireless communication is performed between the transmission unit 221 and the reception unit 311 as in the above embodiment, for example, the communication signal S3 is adjusted by adjusting the radio wave intensity of the communication signal S3 from the transmission unit 221. The destination of can be specified (limited). According to this configuration, the reception area of the communication signal S3 can be automatically set by adjusting the field intensity of the communication signal S3, so that there is an advantage that additional information need not be included in the communication signal S3. .

  In the above embodiment and the first and second modified examples, the communication signal S3 is configured to be transmitted by broadcast, and whether or not the reception side device 3 (processing unit 331) receives the communication signal S3 Is determined. On the other hand, the transmission side apparatus 2 may be configured to specify the range in which the communication signal S3 is received. That is, the transmission side device 2 may be provided with a processing unit that performs processing for specifying the transmission destination of the communication signal S3.

  In the second modification, the setting unit 25 is provided in the transmission side device 2. However, the setting unit may be provided in the reception side device 2, and the setting unit may be provided in the server device 6. .

  Although the above-mentioned embodiment explained the case where the earthquake motion of an earthquake was detected by detection part 21 as an example, it may be constituted so that the sign of an earthquake may be detected by detection part 21. According to this configuration, it is possible to shut off the first electric path E1 in the first management area D1 and the second electric path E2 in the second management area D2 before the occurrence of an earthquake, Safety can be enhanced.

  In the above embodiment, although the case where the communication between the transmitting side device 2 and the receiving side device 3 is wireless communication has been described as an example, for example, power line communication using a power line (Power Line Communication) It is also good. Moreover, when the detached house as management area | region D1, D2 is equipped with the smart meter, you may be comprised so that communication may be performed between smart meters. Furthermore, the wireless communication between the transmitting side device 2 and the receiving side device 3 is not limited to the specific low power wireless communication, but is for portable terminals such as WiFi (registered trademark), 3G, 4G, LTE (Long Term Evolution), etc. It may be wireless communication using the line of

  In the above embodiment, although the case where the first management area D1 and the second management area D2 included in the target area A1 are respectively detached houses has been described as an example, for example, at least one first management area D1 is a power company It may be In this case, if the power company that is the first management area D1 is provided with the detection unit, the communication signal including the detection result of the detection unit is from the power company that is the first management area D1 to the second management area D2. It can be sent to a detached house.

  In the above-mentioned embodiment, although a case where a disaster was an earthquake was explained to an example, a disaster is not limited to an earthquake. The following is a list of disasters other than earthquakes. If the disaster is a fire, the detection unit 21 is a fire sensor that senses the fire by, for example, heat, smoke, flame or the like. In addition, when the disaster is a flood such as heavy rain, heavy snow, flood, storm surge, or tsunami, the detection unit 21 is a sensor for detecting the amount of water, such as a rain gauge. Furthermore, when the disaster is a lightning strike, the detection unit 21 is, for example, a sensor that measures a surge current due to the lightning strike. Moreover, when a disaster is a tornado, a typhoon, etc., the detection part 21 is an anemometer, for example.

  Although the above-mentioned embodiment explained the case where disaster related information was an earthquake map as an example, disaster related information is information decided according to the kind of disaster. When the disaster is a fire, the disaster related information is, for example, wind direction information for each area issued from the Meteorological Agency. In addition, when the disaster is a flood, the disaster related information is, for example, a landslide disaster map issued from a local government. Furthermore, when the disaster is a lightning strike, the disaster related information is, for example, a weather forecast for each area issued from the Meteorological Agency. Further, when the disaster is a tornado, a typhoon or the like, the disaster related information is, for example, an occurrence forecast of a tornado or a typhoon issued from the Japan Meteorological Agency.

  Although the above-mentioned embodiment explained the case where detection part 21 detected one detection subject (earthquake) as an example, detection part 21 may be constituted so that a plurality of detection subjects may be detected. In this case, preferably, the adjustment unit 241 has a plurality of disaster related information. And it is preferable that the adjustment part 241 is comprised so that the disaster relevant information to apply may be changed according to the kind of disaster among several disaster relevant information. Here, the plurality of disaster related information is information corresponding to a plurality of disasters in one-to-one correspondence. For example, if the detection targets of the detection unit 21 are an earthquake and a fire, the adjustment unit 241 selects disaster related information on an earthquake and disaster related information on a fire from among a plurality of disaster related information. According to this configuration, since the disaster related information to be applied is changed according to the type of disaster, the transmission destination of the communication signal S3 can be adjusted according to the type of disaster.

  In the above-described embodiment and the second modification, the adjustment unit 241 is provided in the transmission side device 3, and in the first modification, the adjustment unit 611 is provided in the server device 6, but the adjustment unit is omitted. It is also good.
