Title:
INFLOW GATE CONTROLLER
Document Type and Number:
Japanese Patent JPH03226808
Kind Code:
A
Abstract:
PURPOSE:To prevent dirty water from overflowing from a pump well by executing the control so that a water level of the pump well coincides with a target value by operating an opening of an inflow gate. CONSTITUTION:A water level controller 12 outputs a flow rate control signal to an opening controller 13 so that a measured water level by a pump well water level gauge 27 coincides with a water level set value. A gate number deciding circuit 15 decides the number of gates of an inflow gate 23 which is operated, based an output signal from the water level controller 12 and a water level signal from an inflow ditch water level gauge 24, and instructs it to a gate number control circuit 39. To the circuit 39, in addition thereto, the control signal of a gate opening is inputted, the number of gates of operated gates and an opening signal of the gate are outputted to an inflow gate control circuit 31. In such a way, since the opening of the inflow gate 23 in controlled automatically, discharge of untreated dirty water to the environment is decreased, and the capacity of facilities can be utilized stably and sufficiently.
