Washer control apparatus and control method thereof

Abstract

The invention relates to a washer control apparatus and a control method thereof. The washer control apparatus is characterized by comprising an input device, a water level sensor, an PLC, a solid state relay and a motor pump, wherein the input device is used for inputting a control signal to the PLC, the control signal comprises a washing time, a washing frequency and a washing mode; the water level sensor is used for detecting the liquid level position of the cleaning fluid in a washer and sending a liquid level position signal to the PLC; the solid state relay is used for controlling the starting or stopping of the motor pump; the PLC is used for receiving the control signal of the input device and the liquid position signal of the water level sensor; and the PLC controls the starting or stopping of the motor pump through the solid state water pump so as to realize washing of a head lighter. The washer control apparatus is designed for a light fixture detection lab and is manufactured for a special-purpose head lighter washer. The apparatus has certain intelligent and automation control by use of software to perform programming on the PLC.

Description

technical field [0001] The invention relates to the field of car washer detection equipment, in particular to a washer control device and a control method thereof. Background technique [0002] Most of the cleaners used for cars are temporarily built with simple-function PLC modules or relays. There is often no display device, which is not intuitive, and the wiring is not clear. It is difficult to check when there is a problem with the line. [0003] Each washer manufacturer often only produces one or several types of washer, and the customers are relatively fixed; and most of the control circuits inside the washer are composed of single-chip microcomputers or counter modules, which only control the cleaning time and frequency of a certain car ; The control strategy cannot be adjusted at any time according to the different automobile products, which limits the application range of the washer. Contents of the invention [0004] The technical problem to be solved by the pre...
