Title:
WATER CHANNEL CONTROL SYSTEM
Document Type and Number:
Japanese Patent JPH05100710
Kind Code:
A
Abstract:
PURPOSE:To provide a water channel control system capable of executing smooth automatic control by absorbing simply and successively the change of the situation of an upstream side at a downstream side in respect of a control system in the measurement and control system of a water channel provided with plural monitor and control stations. CONSTITUTION:This channel control system is constituted as follows. In each monitor and control station installed at plural weirs of a water channel, a line switching means 1 is provided so as to switch whether information from an upstream station is fetched and the information of its own station is sent to a downstream station or the information of the upstream station is transferred to the downstream station as it is, and a communicating means 2 is provided so that the information from the upstream station is received and the information of its own station is transmitted to the downstream station, and a control means 3 is provided so as to control the gate of its own station by calculating the flow rate controlled variable of its own station from the flow rate controlled variable of the upstream station and the flow rate and the water level and the opening of a gate of its own station, and simultaneously, the information of the flow rate controlled variable is outputted to the communicating means 2, and each monitor and control station transfers this controlled variable information successively to the downstream station, and executes the flow rate control of its own station by adding the significant control information of the just preceding upstream station.
