なくなった事を検出して伝送異常を出力することを特徴
とする遠方監視制御装置。In a remote monitoring and control device that transmits display and measurement signals from a slave station to a master station via a relay station, a constant signal is sent to the slave station to detect that the display and measurement signals of the slave station are not being transmitted correctly to the master station. An oscillator that repeats 0N-OFF during the station period is provided, and this oscillation signal is transmitted to the master station as a display signal, and the master station detects when the display signal does not change its ON or OFF state for a certain period of time or more. A remote monitoring and control device characterized in that it outputs a transmission abnormality.
