Abstract

PURPOSE:To detect a no-response signal by constituting a master station (remote supervisory controller) and an intercepting station almost identical, changing the operation of a control section at the master station so as to start the polling operation by a receiving signal and comparing the receiving signal with the polling signal even if the master station acts like the intercepting station. CONSTITUTION:A control section 1 receives information from a station code counter 2, transmits a polling signal and calls a slave station (remote control station to be supervised). Then, a signal transmitted from the slave station is received by a supervisory section 3, a receiving station code counter 5 receives a receiving station code from the supervisory section 3 and the station code of the slave station to be subject to polling is transmitted to the station code counter 2. Further, the receiving station code counter 5 compares the station code subject to polling before with the received station code to detect the presence of response. When the master station is used as the intercepting station, it is realized simply by stopping the operation of the control section 1.

In FIG. 1, 1 represents a control section, 2 a station code counter, 3 a monitoring section, and 4 a station code collation section.

憶し、監視していた。In the prior art, the control section 1 controls the polling station, and only receives the monitored control signal from the slave station (remotely monitored and controlled station) by the monitoring section 3 and confirms the signal. The control unit 1 works in conjunction with the station code counter 2, sequentially calls the slave stations (remotely monitored and controlled stations), and the monitoring unit 3 receives signals sent from the slave stations (remotely monitored and controlled stations).
The station code collation section 4 checks the signal to confirm that it is definitely the signal from the called slave station, and then stores and monitors the data.

はならないと云う欠点かあ、った。Therefore, when trying to use a master station (remote monitoring and control device) designed with this kind of configuration as an interception station, the signal from the remote monitoring and control device must be intercepted by the device to be intercepted.
Even if I can't receive it, I can't publish it if I don't receive a response. This is because the no-response 7 information is received from the control unit as ``1'' control signal - rule, and a mechanism is adopted to compare it with ``No. 4.'' In other words, only control unit 1 is connected to the poll. This is because it controls the station 2, and a master station like this (remote monitoring and control device" + W)
The drawback was that in order to change it to a wiretapping station, a major change would have to be made to Proposition 1.
