INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract An object is to reduce influence of erroneous operation in a monitoring system provided with a sensor. Lighting equipment is to be turned on by means of main power. A remote control device turns off the lighting equipment. A battery supplies reserve power. A sensor performs predetermined measurement by means of the main power. A detector detects whether or not supply of the main power has been stopped by operation of a predetermined switch, and generates a detection result. A communicator transmits the detection result by means of the reserve power in a case where the supply of the main power has been stopped. ## Claims ### Claim 1 A monitoring system comprising: lighting equipment to be turned on by means of main power; a remote control device configured to turn off the lighting equipment; a battery configured to supply reserve power; a sensor configured to perform predetermined measurement by means of the main power; a detector configured to detect whether or not supply of the main power has been stopped by operation of a predetermined switch, and generate a detection result; and a communicator configured to transmit the detection result by means of the reserve power in a case where the supply of the main power has been stopped. ### Claim 2 (depends on 1) The monitoring system according to claim 1, further comprising: a selector configured to select any of the main power and the reserve power on the basis of the detection result to supply the main power or the reserve power to the communicator. ### Claim 3 (depends on 2) The monitoring system according to claim 2, further comprising: an auxiliary battery configured to supply auxiliary power to the selector until the main power is switched to the reserve power. ### Claim 4 (depends on 1) The monitoring system according to claim 1, wherein the battery is charged with the main power to supply charged power to the communicator in a case where the supply of the main power is not stopped, and supplies, as the reserve power, the charged power to the communicator in a case where the supply of the main power has been stopped. ### Claim 5 (depends on 1) The monitoring system according to claim 1, further comprising: a controller configured to lower power consumption of the sensor in a case where the supply of the main power has been stopped. ### Claim 6 (depends on 5) The monitoring system according to claim 5, wherein the sensor includes two sensors different from each other in power consumption, and the controller drives one, whose power consumption is higher, of the two sensors in a case where the supply of the main power is not stopped, and drives one, whose power consumption is lower, of the two sensors in a case where the supply of the main power has been stopped. ### Claim 7 (depends on 1) The monitoring system according to claim 1, wherein the communicator determines, in a case where the supply of the main power has been stopped, whether or not an elapsed time from start of the supply of the main power to a current time is longer than a predetermined time, and transmits the detection result when the elapsed time is longer than the predetermined time. ### Claim 8 (depends on 1) The monitoring system according to claim 1, further comprising: an information terminal configured to receive and display the transmitted detection result. ### Claim 9 Electronic equipment comprising: a battery configured to supply reserve power; a sensor configured to perform predetermined measurement by means of main power supplied to lighting equipment; a detector configured to detect whether or not supply of the main power has been stopped by operation of a predetermined switch, and generate a detection result; and a communicator configured to transmit the detection result by means of the reserve power in a case where the supply of the main power has been stopped. ### Claim 10 A monitoring system control method comprising: a lighting step of turning on lighting equipment by means of main power; a measurement step of performing predetermined measurement by a sensor by means of the main power; a detection step of detecting whether or not supply of the main power has been stopped by operation of a predetermined switch, and generating a detection result; and a communication step of transmitting the detection result by means of reserve power supplied from a battery in a case where the supply of the main power has been stopped.
