あった。(b), Prior Art and Problems In the conventional polling method, when a supervisory control station (master station) monitors and controls a group of monitored and controlled stations (slave stations), the master station wants to monitor and control the child station. The stations are sequentially called and commands are sent out, and only the corresponding slave stations respond by sending out their own data and reporting their own status, and are controlled. Therefore, since there are many signals from the supervisory control station (master station) or signals from the monitored control station (slave station) that are polled by the supervisory control station (master station), the transmission path is subject to supervisory control. The disadvantage was that the station (master station) had to be -.

。(d) 1 Structure of the Invention According to the present invention, the above object is to provide a supervisory control system that controls a group of monitored control stations using a polling method, which has a plurality of supervisory control stations, When the supervisory control station 1 is controlling by sending out a polling signal, the other supervisory control stations maintain the status of monitored control stations, and any supervisory control station other than the supervisory control station ■ controls the station. When the own station is polling 41, it polls on behalf of the supervisory control station I every time it sends a control station switching signal.
This is achieved by providing a polling system in which supervisory control is performed from a plurality of stations.

ング４８号を送出し始める。There are multiple monitoring control stations (master stations), and each monitoring control station (master station) receives the information signal νJ sent from the monitored control station (slave station). (1) Monitoring operation status and monitoring control station It is possible to switch to (2) control operation state as a (master station). That is, the supervisory control station (master station) always receives (11) signals sent from the monitored control station (slave station) and is in the monitoring operation state. When its own station is polled, i.e., called, it sends control station switching information to another monitoring control station (master station) and enters the (2) control operation state.The monitoring station that received this control station switching information The control station (master station) (1) switches to the monitoring operation state and stops sending out the boring signal.The supervisory control station (master station) that sent the control station switching information <= a
After making sure that other monitoring + fil + your station (master station) does not send out polling signals for a certain period of time, your own station starts sending polling No. 48.

監視制御局（親局）が制御を可能にする方式である。In this case, a supervisory control station that sends out a polling signal (
The master station) is actually one station, but multiple supervisory control stations (master stations) can monitor multiple stations by switching to a controllable supervisory control station (master station) by transmitting control station switching information. This method allows a control station (master station) to perform control.

てポーリング動作に入る。In such a situation, if you want to control from supervisory control station B, when supervisory control station A calls supervisory control station B, a polling stop signal (1) is added to the response signal and sent. When supervisory control station A receives a polling stop signal from supervisory control station B, it stops the boring operation.After transmitting the above signal, supervisory control station B must ensure that no polling signal is sent from other supervisory control stations for a certain period of time. After confirming @, the polling operation begins.That is, the transmission stop command to the transmission stop section 4 of the own station is canceled, the supervisory control transmission logic section 2 is activated, and the polling operation begins.
