Vehicle light controller for urban rail vehicle

Abstract

The invention relates to the technical field of vehicle lights, in particular to a vehicle light controller for an urban rail vehicle. The vehicle light controller for the urban rail vehicle comprisesa light controller I and a light controller II; light controller circuits are arranged on the light controller I and the light controller II; the light controller circuits comprise input ends, outputends and communication ends; the input ends are connected with braking signals, double flash signals, activating signals, lower beam modes, high beam modes, width modes, left steering signals, rightsteering signals, flashing light signals, daytime running light switching signals, fog light switching signals and light state detecting signals; the output ends are connected with braking lights, lower beams, high beams, width lights, left steering lights, right steering lights, vehicle width lights, fog lights, daytime running lights and tail lights; and the communication ends are connected withRS85 buses. The vehicle light controller for the urban rail vehicle has the advantages that complex logic simplifying effect on the vehicle light control is realized; the control synchronization of the vehicle lights at two ends is realized; redundancy designs of safety related key signals on software and hardware are all realized; and the reliability is improved.

Description

technical field [0001] The invention relates to a vehicle light controller, in particular to a vehicle light controller for urban rail vehicles. Background technique [0002] In the design phase of the existing tram line 1 vehicle scheme, the original light control logic was realized by hard wires, but the vehicle has many penetrating lines and a large number of switch button points, making it difficult to realize; after further optimization of the scheme, the on-board microcomputer and input The realization of the output node module greatly reduces the penetration line and the number of switch button points, but it needs to occupy more input and output nodes, and the node module purchase cost is high, the economy is poor, and it cannot meet the independence requirements of the car light control. The car light needs to be independent from the Other systems work. Contents of the invention [0003] The present invention aims to solve the above defects, and provides a light ...
