<p><P>PROBLEM TO BE SOLVED: To provide a remote monitoring control system that eliminates signal detection malfunction by transmitting and receiving communication between monitoring control devices without dispatching a worker. <P>SOLUTION: In a remote monitoring system including a slave station 3 and a master station 2, the master station 2 and slave station 3 are configured to have a function of amplifying and changing a transmission signal and be able to switch a normal mode for performing normal transmission and reception and an amplification factor change mode for changing an amplification factor. The remote monitoring system is configured, in the amplification factor change mode, to perform a step ST104 during which the master station 2 intermittently transmits a first test signal while gradually increasing the amplification factor, a step ST207 during which the slave station 3 returns a second test signal to the master station 2 if the slave station 3 has realized the first test signal, a step ST110 during which the master station 2 sets the amplification factor based on the amplification factor of the first test signal, transmits a completion signal to the slave station 3, and moves to the normal mode if the master station 2 realized the second test signal, and a step ST210 during which the slave station 3 obtains the completion signal from the master station 2 and sets the amplification factor corresponding to the amplification factor of the master station 2, and then to return to the normal mode. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
