In other words, the coordinating unit 241 adjusts the transmission destination of the communication signal S3 based on the disaster-related information. The "disaster-related information" here is information for specifying the range affected by the disaster, and is, for example, an earthquake map issued by a local government or the like when the disaster is an earthquake. Then, based on this earthquake map, the adjustment unit 241 sets (adjusts) the area where an earthquake with a magnitude of seismic motion equal to or greater than the threshold value occurs as the transmission destination of the communication signal S3.

The control unit 33 is configured to determine the magnitude of seismic motion due to an earthquake based on the detection result of the detection unit 21 included in the communication signal S3 received by the reception unit 311. Then, if the magnitude of the seismic motion is equal to or greater than the threshold value (for example, seismic intensity 5), the control unit 33 determines that the second electric line E2 in the second control area D2 should be cut off, and cuts off the second electric line E1. 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 according to the control signal from the control unit 33.

Further, the control unit 33 has 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 includes itself based on the area information included in the communication signal S3 received by the receiving unit 311 and its own position information. 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.

(3) Operation Next, the operations of the disaster detection system 1 and the power cutoff 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 cutoff system 10 will be described with reference to FIG. In the following description, it is assumed that an earthquake with a seismic intensity of 5 or higher occurs in the first target area A11. Since the same operation is performed in the second target area A12 and the third target area A13, the description thereof will be omitted here.

From the detection result of the detection unit 21, the control unit 24 of the transmission side device 2 determines that an earthquake has occurred if the magnitude of the earthquake motion is equal to or greater than a threshold value (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 broadcast the created communication signal S3 (step ST2). At this time, the adjustment unit 241 of the control unit 24 sets (adjusts) the area (target area) to which the communication signal S3 should be transmitted based on the disaster-related information related to the earthquake.

Further, since the magnitude of the earthquake motion is equal to or larger than the threshold value, the control unit 24 outputs a control signal for blocking the first electric path E1 to the first output unit 23. The first output unit 23 outputs the first cutoff signal S1 to the first cutoff unit 41 according to the control signal from the control unit 24. Then, the first cutoff unit 41 cuts off the first electric circuit E1 according to the first cutoff signal S1 from the first output unit 23 (step ST3).

On the other hand, since the receiving side device 3 is not provided with the detection unit, 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 or not the receiving unit 311 has received the communication signal S3 from the transmitting side device 2 (step ST4). If the receiving unit 311 receives the communication signal S3 (Yes in step ST4), the control unit 33 determines whether or not the condition for acquiring the detection result of the detection unit 21 included in the communication signal S3 is satisfied. Determine (step ST5). The "condition" referred to here means that the receiving side device 3 is included in the target area adjusted by the adjusting 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 broadcast the communication signal S3 (Yes). Step ST2). Here, it is preferable that the number of hops is set so that the retransmission of the communication signal S3 can be restricted.

Further, the control unit 33 determines whether or not the magnitude of the earthquake motion is equal to or greater than the threshold value based on the detection result of the detection unit 21, and if the magnitude of the earthquake motion is equal to or greater than the threshold value, the control for shutting off the second electric circuit E2. The signal 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 according to the control signal from the control unit 33. Then, the second cutoff unit 71 cuts off the second electric path E2 according to the second cutoff signal S2 from the second output unit 32 (step ST3).

The control unit 33 ends the operation when the receiving unit 311 does not receive the communication signal S3 (No in step ST4) or when the above conditions are not satisfied (No in step ST5). After that, the disaster detection system 1 and the power cutoff system 10 periodically execute the operations of steps ST1 to ST5 described above.

(3.2) Second Operation Example Next, a second operation example of the disaster detection system 1 and the power cutoff system 10 will be described with reference to FIG. In the following description, it is assumed that the receiving side device 3A is included in the target area adjusted by the adjusting unit 241 and the receiving side 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 broadcast the created communication signal S3 (step ST12). At this time, the adjustment unit 241 of the control unit 24 sets (adjusts) the area (target area) to which the communication signal S3 should be transmitted based on the disaster-related information related to the earthquake.

Further, since the magnitude of the seismic motion is equal to or greater than the threshold value (for example, seismic intensity 5), the control unit 24 outputs a control signal for blocking the first electric path E1 to the first output unit 23. The first output unit 23 outputs the first cutoff signal S1 to the first cutoff unit 41 according to the control signal from the control unit 24. Then, the first cutoff unit 41 cuts off the first electric circuit E1 according to the first cutoff signal S1 from the first output unit 23 (step ST13). On the other hand, since the receiving side devices 3A and 3B are not provided with the detection unit, the control unit 33 of the receiving side devices 3A and 3B does not detect the occurrence of an earthquake.

Upon receiving the communication signal S3 from the transmitting side device 2A, the control unit 33 of the receiving side device 3A determines whether or not the above conditions are satisfied. Here, since the receiving side device 3A is included in the target area adjusted by the adjusting unit 241, the control unit 33 acquires the detection result of the detecting unit 21 included in the communication signal S3. Further, the control unit 33 causes the communication signal S3 to be transmitted by broadcast from the communication unit 31 (step ST14).

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

Since the magnitude of the seismic motion due to the earthquake is equal to or greater than the threshold value from the detection result of the detection unit 21 included in the communication signal S3, the control unit 33 of the receiving side device 3A sends a control signal for blocking the second electric path E2. 2 Output to the output unit 32. The second output unit 32 outputs the second cutoff signal S2 to the second cutoff unit 71 according to the control signal from the control unit 33. Then, the second cutoff unit 71 cuts off the second electric path E2 according to the second cutoff signal S2 from the second output unit 32 (step ST15).

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 the communication signal S3 including the detection result of the detection step. The first output step is a step of outputting a first cutoff signal S1 for shutting off the first electric circuit E1 in the first management area D1 based on the detection result of the detection step. The reception step is a step of receiving the communication signal S3 transmitted in the transmission step. The second output step outputs a second cutoff signal S2 for blocking the second electric circuit 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's a step. The adjustment step is a step of adjusting the transmission destination of the communication signal S3 based on the disaster-related information which is the information for specifying the range affected by the disaster.

(5.1) First Modified Example In the above-described embodiment, the case where the transmitting side device 2 and the receiving side device 3 directly communicate with each other has been described as an example, but as shown in FIG. 5, the transmitting side device 2 and the transmitting side device 2 have been described. The receiving device 3 may be configured to communicate with the server device 6 via the server device 6. Hereinafter, a first modification of the disaster detection system 1 and the power cutoff system 10 will be described with reference to FIG.

As shown in FIG. 5, the disaster detection system 1 according to the first modification includes a transmitting side device 2 and a receiving side device 3. The transmitting side device 2 includes a detecting unit 21, a communication unit 22, a first output unit 23, and a control unit 24.

The communication unit 62 is a communication interface for communicating with the communication unit 22 of the transmission side device 2 and the communication unit 31 of the reception side device 3. The communication unit 62 is configured to perform wireless communication with the communication units 22 and 31.

The communication unit 62 receives the 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 about the target area adjusted by the adjustment unit 611 to the communication signal S3, and transmits the communication signal S3 to the receiving side device 3.

The storage unit 63 is composed of a readable and writable memory. The storage unit 63 is, for example, a flash memory. The storage unit 63 stores a plurality of disasters and a plurality of disaster-related information in association with each other.

The operations of the disaster detection system 1 and the power cutoff system 10 are the same as those of the above-described embodiment except that the communication signal S3 is transmitted via the server device 6, and therefore, the disaster detection system 1 and the electric power are described here. The description of the operation of the shutoff system 10 will be 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 seismic motion equal to or greater than the threshold value has occurred, a communication signal including the detection result of the detection unit 21 All that is required is to send S3 to the server device 6.
