Abstract

This application discloses a self-control safety protection method for a photoelectric water control system, which includes: real-time detection of the actual operating frequency of the pump motor of the photoelectric water control system; The actual operating frequency of the water pump motor is reduced to the frequency threshold; if the actual operating frequency is less than the frequency threshold, the speed of the water pump motor is adjusted so that the actual operating frequency of the water pump motor increases to the frequency threshold. The photoelectric water control system self-control safety protection method provided by this application can adjust the speed of the water pump motor in real time according to the actual operating frequency of the water pump motor of the photoelectric water control system, so as to ensure that the water pump motor is in a safe working state, which solves the problem of the existing photoelectric water control system. The water control system lacks an automatic protection function, and cannot protect the water supply equipment of the photoelectric water control system well, which affects the service life of the water supply equipment.
