客车照明与信号灯多路传输控制系统的设计

本文以客车照明与信号灯的位置分布和安全性要求作为节点划分依据，采用控制器局
域网CAN（Controller Area Network）构建了客车照明与信号灯多路传输控制系统，设计了系统结构、节点、相关流程图与硬件结构图，并采取指令控制——状态检测——状态指示的控制方式，实现车灯状态自动检测，增强客车行驶安全性。

Design of Passenger Car Illumination and Signal Lamp Multiplexing Control System
HU Jian, LI Gangyan, WU Xiude, ZHOU Jianhua (School of Mechanical & Electronic Engineering, Wuhan University of Technology, Wuhan, China 430070.) Abstract: The author constructs passenger car illumination and signal lamp multiplexing control system based on CAN (Controller Area Network) and designs system structure, node parameters, correlative flow chart and hardware framework. The design of system node is according to the position and security of passenger car illumination and signal lamp. This paper uses the control
method of command control----status testing----status indication to realize passenger car lamp status automotive test and enhance passenger car‘s security.
