Abstract
This invention relates to a control method for a remote supervisory control system which includes a single master station and N (plural) remote stations sporadically lying in distant places, said method used for supervising and controlling the states of the N remote stations by the single master station. Since the method is of the type in which the one master station supervises and controls the states of the N remote stations, it is also termed the 1-to-N remote supervisory control method. The master station supervises the remote stations by indicating, for example, the 'on' and 'off' states of circuit breakers on the basis of signals from the remote stations, and controls the states of the remote stations by transmitting 'off' and 'on' control signals conversely from the master station to the remote stations.
