を備えたことを特徴とする遠方監視制御装置。[Scope of Claim for Utility Model Registration] The collected information on the monitored equipment is sent cyclically to the master station, usually by wire, and when the line is disconnected, a call signal is detected from the master station using wireless on the backup transmission line. What is claimed is: 1. A remote monitoring and control device that cyclically transmits signals to a master station by radio, comprising a reset circuit that resets a transmission address counter when the calling signal is detected when a line is disconnected.
