Title:
RAINWATER DRAINAGE PUMP CONTROL DEVICE, RAINWATER DRAINAGE PUMP CONTROL METHOD, RAINWATER DRAINAGE PUMP CONTROL PROGRAM, AND PARAMETER PROVIDING DEVICE
Document Type and Number:
Japanese Patent JP2015025353
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a rainwater drainage pump control device that properly controls a rainwater drainage pump.SOLUTION: A rainwater drainage pump control device of the embodiment has a water-level setting part and a pump control part. The water-level setting part includes: a function for finding a correlation coefficient by shifting time with respect to time series information of several kinds of drainage area monitoring data and time series information of inflow of rain water to a storage part with the rain water flowing therein, and extracting the drainage area monitoring data in which the correlation coefficient exceeds a predetermined value; and a function for calculating a delay time and a contribution degree between the extracted drainage area monitoring data and the inflow of the rain water to the storage part, based on a sliding time when the correlation coefficient becomes the maximal value, and setting a starting water-level with respect to each of the multiple rainwater drainage pumps, based on the calculated delay time and the contribution degree. The pump control part starts a rainwater drainage pump in which the water-level of the storage part becomes the starting water level or more, among the multiple rainwater drainage pumps.
