The movement presence / absence determination shown in FIG. 3 is performed every first time t1 (for example, t1 = 1 second).

In step S11, the control unit 35 determines whether or not the radio wave intensity of the radio wave of the second signal transmitted from the transmission unit 10 is within a predetermined range.
Further, the control unit 35 determines the radio wave intensity of the radio wave of the first signal from the other transmitting unit 10 when receiving the radio wave of the first signal transmitted from the other transmitting unit 10 included in the second signal. Judge whether it is within the range of.

If any of the radio wave intensities is not within the predetermined range, it is determined that there is a high possibility that an abnormality has occurred in the monitored area 100, and the process proceeds to step S12.
If the radio wave strength of any of them is within a predetermined range, it is determined that there is a low possibility that an abnormality has occurred in the monitored area 100, and the procedure is terminated.

In step S12, the control unit 35 operates the direction control unit 25 so that the detection device of the detection unit 21 and the image pickup surface of the image pickup unit 23 face a predetermined portion of the monitoring target area 100. Further, the control unit 35 drives the moving unit 33 to move the monitoring device 20 to a desired position.

When the radio wave intensity of the second signal from the transmitting unit 10 is not within a predetermined range, the control unit 35 has the detection device of the detecting unit 21 and the imaging surface of the imaging unit 23 with the transmitting unit 10. The direction control unit 25 is operated so as to face the area including the monitoring device 20. Further, the control unit 35 drives the moving unit 33 to move the monitoring device 20 near the area including the transmitting unit 10 and the monitoring device 20.

When the radio wave intensity of the radio wave of the first signal from the other transmitting unit 10 is not within a predetermined range, in the control unit 35, the detection device of the detecting unit 21 and the imaging surface of the imaging unit 23 are the transmitting unit 10.

After the second time t2 (for example, t2 = 5 minutes) has elapsed from the power supply stop control in step S14, in step S15, the control unit 35 outputs the monitoring result information to the communication unit 27 as the power supply device. The power supply side communication unit 50a of 50 is made to transmit the third signal regarding the stop of operation.
As a result, the power supply 51 to be tested is turned off, the power supply from the power supply device 50 to the power supply device 60 is stopped, and the cooling unit 53 is also stopped.

If the cooling unit 63 operates based on the power supply from a device other than the power supply 51 to be tested, in step S15, after the second time t2 has elapsed from the power supply stop control in step S14, The control unit 35 causes the communication unit 27 to transmit the fifth signal regarding the stop operation of the cooling unit 63 to the power supply side communication unit 60a as the output of the monitoring result information.

That is, after the power supply from the test target power supply 51 to the resistance unit 61 is cut off and the monitoring result information (third signal) is received by the power supply side communication unit 50a, the power supply to the cooling unit 63 is stopped. ..

If the radio wave strength of any of them is within a predetermined range, it is determined that there is a low possibility that an abnormality has occurred in the monitored area 100, and the procedure is terminated.

In step S22, the control unit 35 operates the direction control unit 25 so that the detection device of the detection unit 21 and the image pickup surface of the image pickup unit 23 face a predetermined portion of the monitoring target area 100. Further, the control unit 35 drives the moving unit 33 to move the monitoring device 20 to a desired position.

In step S23, the control unit 35 determines whether or not there is an abnormality in the monitored area 100 based on at least one of the first information obtained by the detection unit 21 and the second information obtained by the imaging unit 23. ..

If it is determined that no abnormality has occurred, the procedure ends.
If it is determined that an abnormality has occurred, the process proceeds to step S24.

In step S24, the control unit 35 determines whether or not the abnormality in the monitored area 100 is related to a power failure.

If the light or the like is turned off and the brightness of the obtained image is lower than the normal one from the image information (second information) obtained by the imaging unit 23, there is a possibility that a power failure has already occurred. ..
In addition, when a fire breaks out and the oxygen content information (first information) is lower than the normal information from the information (first information) about the specific substance obtained by the detection unit 21, the carbon dioxide content is normal. If it is higher than the normal one, if the obtained image is different from the normal one (smoke is included in the image) from the image information (second information) obtained by the imaging unit 23, a power failure will occur in the future. there's a possibility that.

If there is a possibility that a power failure has already occurred, or if there is a possibility that a power failure will occur in the future, it is determined that the abnormality in the monitored area 100 is related to the power failure, and the process proceeds to step S25. ..
If not, it is determined that the abnormality in the monitored area 100 is not related to the power failure, and the process proceeds to step S26 without going through step S25.

In step S25, the control unit 35 causes the communication unit 27 to transmit the sixth signal regarding the start of operation to the power supply side communication unit 50a as the output of the monitoring result information.
As a result, the emergency generator 52 is turned on. After the emergency generator 52 is in steady operation, power can be supplied to the load 62 via the second switching unit 66.
Therefore, after the power supply from the commercial power source is stopped and the switching control of the second switching unit 66 is performed, the power supply from the emergency generator 52 to the load 62 becomes possible in a short time.

In step S26, the control unit 35 causes the communication unit 27 to transmit information such as an abnormality occurring in the monitored area 100 to the external device 90 as an output of the monitoring result information.
This makes it possible to notify the user of the external device 90 that an abnormality has occurred in the monitored area 100.
