The control unit 300 of the slave station active system 30 checks the “change information from the previous time” in the monitoring information storage unit 400 according to the above. When “1” is present, the response information indicating the state change is transmitted from the transmission unit 200 to the master station 1.
Return to 0. When the receiving unit of the slave station standby system 40 requests the transmission of the monitoring information from the master station 10 via the preliminary rotation according to the response information, the control unit of the slave station standby system 40 sets the slave station standby system 40
The detailed report information is called from the monitoring information storage unit, and is transmitted from the transmission unit of the slave station standby system to the master station 10 via the protection line.

ができる効果がある。As described above, the present invention provides change information returning means for storing and returning the presence or absence of a state change in preset state information from the previous polling call as response information to the polling call. And information reporting means for reporting internal state information via a line different from the line used for polling call in response to a request from the master station when information having a state change is returned. Effectively use the two spare lines and perform polling monitoring to minimize the polling cycle on at least one line by making the polling call response information indicate whether or not the status has changed since the previous call. Since the detailed information of the slave station monitoring information is collected using the other line, the same amount of information as in the conventional method can be collected, and the delay of information collection is minimized. Can be suppressed to, also, even in failure or the like in the slave station, there is an effect that can be quickly addressed in the master station.
