Remote supervisory control equipment

Abstract

Abstract PURPOSE:To attain easily and surely changeover by slave stations of systems I and II by adopting the constitution that a changeover section allows a transmission section to switch slave station line selection information and a slave number of a transmission data of a system I or II and to fetch alternately a reception data from a reception section of the systems I and II thereby obtaining a reception data of a corresponding slave station. CONSTITUTION:The change over section is provided with a decoding circuit 71 decoding a slave station number data of a transmission data, a line state discrimination logic circuit 72 discriminating to which line of systems I, II of the transmission line each salve station from slave station selection information is connected, a line selection circuit 73 obtaining a line selection command as to a transmission destination slave station of the transmission data from a decoding signal of the decoding circuit and a discrimination output of the logic circuit, a gate circuit 74 using the selection command and outputting distributingly the transmission data to the transmission section of the systems I, II and a gate circuit 75 fetching alternately the reception data from a couple of reception sections and obtaining the reception data. The transmission changeover is discriminated by using the slave station number and line selection information of the transmission data and the reception data is obtained by fetching alternately the data of a couple of the reception sections.
