Light control module

Abstract

The invention provides a light control module, which comprises an MCU chip, a light signal input detection circuit, a first photoelectric isolation circuit, a first indication lamp, a light signal output circuit, and a light circuit fault detection circuit, wherein the MCU chip is used for controlling input and output of light signals and fault detection; the light signal input detection circuit comprises a first anti-impact circuit for eliminating input spikes and preventing voltage impact; the first photoelectric isolation circuit is used for isolating high voltage signals in the light signals and then inputting the light signals to the MCU chip; the first indication lamp is used for indicating the light signals; the light signal output circuit outputs corresponding light signals according to the instruction of the MCU chip; and the light circuit fault detection circuit at least comprises a current detection chip for determining fault of the light circuit through detecting current changes in the light circuit. Problems of complicated wiring in the case of circuit fault detection on the light control module, reduced electrical system stability, and a large wiring amount and large occupied space of the whole light control module can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of electronic circuits of mechanical equipment, in particular to the technical field of lighting control for tank trucks, specifically a lighting control module. Background technique [0002] The tanker is a kind of metallurgical wheeled transportation equipment, and its working environment is complex and harsh. Lighting is an essential lighting and model equipment for tank trucks. There are 12 lights including left and right steering, high beam, low beam, small light, brake, reversing, fog lights, front and rear work lights, auxiliary work lights, and warning lights. Special warning lamps will also be added in more complicated or dusty areas to ensure the safe production of tank trucks and other equipment. [0003] With the development of power electronics technology, the electrical system is becoming more and more intelligent and informatized. The electrical system of the tank truck not only needs to real...
