<p><P>PROBLEM TO BE SOLVED: To certainly receive a signal in no relation to an earthquake other than an earthquake detection signal by enhancing utilization efficiency of a communication line in occurrence of earthquake. <P>SOLUTION: The remote monitoring system is provided with an earthquake detection control part 12 of an object to be monitored provided with earthquake sensors 15, 16 for detecting first and second signals transmitted with time difference in occurrence of earthquake, a control operation activation signal generation means 122 for transmitting a switching signal for activating a control operation mode of an elevator based on the detection of the first signal to an operation control part 11, an elevator stopping instruction signal generation means 124 for transmitting a stopping instruction signal of the elevator to the operation control part based on detection of the second signal, and an earthquake detection signal transmission means 125 for transmitting the sensor detection signal to the communication line 3 at the time when the second signal is detected; and a monitoring device 2 connected to the communication line and monitoring the sensor detection signal transmitted from the earthquake detection control part of the object to be monitored interspersed at a wide area. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
