Device and method for controlling headlamp cleaner

Abstract

The invention discloses a device and a method for controlling tests for a headlamp cleaner. The device is characterized in that a PLC (programmable logic controller) is externally connected with a 24V power source and defines on and off of input pins, turn-on information of the pins is converted into input information, and output signals are transmitted onto an input end of a solid-state relay via wiring terminals after the input information is computed by a kernel of the PLC; input equipment outputs control signals to the PLC, an output wiring end of the PLC and the input wiring end of the solid-state relay are the same wiring end, the electric signals are outputted to the solid-state relay by the PLC, an output wiring end of the solid-state relay and an input wiring end of a water pump with a motor are the same wiring end, amplified electric signals are outputted to the water pump with the motor by the solid-state relay, and on-off frequency and the turn-on time of the water pump with the motor are controlled, so that headlamps can be cleaned by the headlamp cleaner. The device and the method have the advantages that the headlamps of different types of automobiles can be cleaned by the cleaner, the application range of the cleaner is expanded, and the troubleshooting efficiency is improved.

Description

technical field [0001] The invention relates to the field of detection equipment for an automobile headlamp washer, in particular to a control device for a headlamp washer and a control method thereof. Background technique [0002] Most of the cleaners used for headlights are temporarily built with simple-function PLC modules or relays, often without display devices, which are not intuitive, and the wiring is not clear, and it is difficult to check when there is a problem with the wiring. [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.
