Abstract

PURPOSE:To exercise remote monitoring control with high control precision, by transmitting general information words without omission even in the middle of adjustment control over a subordinate station by a master station. CONSTITUTION:A motor driven valve 5 provided on a water conduit 4 piped at a subordinate station is opened and closed to vary the quantity and hydraulic pressure of water flowing through the water conduit 4. The water conduit 4 is provided with a flow detector 6 and a pressure detector 7, and further provided with an opening extent detector 12 which detects the opening and closing state of the valve 5. Data obtained by the detectors 6, 7 and 12 are sent from a subordinate station remote controller 2 to a master station remote controller 1. The master station is provided with an indicator 9 for the opening extent of the motor driven valve, an indicator 10 for the quantity of flow, a pressure indicator 11, and an operation switch 8 for selecting the motor driven valve, and data, such as the opening and closing state of the motor driven valve, the quantity of flow, and pressure, detected at the subordinate station are displayed on the indicators 9-11. An operator adjusts and controls the switch 8 while comparing and monitoring pieces of information on the indicators 9-11.
