Abstract

PURPOSE:To eliminate necessity of two-way transmission lines by making plural supervised stations use one supervisory signal carrier in common, and making the supervisory station receive supervisory data sent one-sidedly from these supervised stations and indicate the data. CONSTITUTION:Supervisory signal carrier is generated from a supervised station which is at the farthest from a supervisory station M. Station name codes (RiADD) of all supervised stations, supervisory data (RiDATA) of own station, check codes (CRC) etc. are incorporated in the carrier according to code format, and sent to the supervisory station M. When a supervised station, for instance R2 which lies on the way, receives this supervisory signal carrier, the station detects the station name code R2ADD of own station and incorporates its own supervisory data in subsequent code part of R2DATA, and sends out again to next supervised station R1. In R1 station too, the station adds its own supervisory data R1DATA after its own station name code R1ADD, and sends out to the supervisory station M.
