Automatic operation control method of drainage machine by reservoir water level management

摘要

PURPOSE:To facilitate control by installing a sequencer having a calendar function and capable of inputting the weather mode such as rain or shine on the water level control device of a distributing reservoir, comparing and calculating the preset pattern and experimental pattern of water delivery, and estimating and controlling the operation so that the deviation between the input/output water quantities is not increased. CONSTITUTION:A sequencer having a calendar function is installed on a control device 57 monitoring the water level of a distributing reservoir 55 storing the inflow water from multiple water filters 54 and directing the operation or stop of the water filters 54 in response to the water delivery. The weather mode such as rain or shine can be inputted to the sequencer, and the preset values of the daily pattern can be easily corrected. The daily pattern of the water level is set to the sequencer, the water level of the distributing reservoir 55 is measured with a water level gauge 56, and the deviation between the water delivery and the inflow quantity is calculated and estimated. The operation and stop of the water filters are controlled so that the deviation is not increased. The water quantity of the distributing reservoir can be easily controlled.
