为了确保车灯的质量可靠性。提出了一种嵌入式车灯控制及电气参数检测系统的设计方案。系统包括上位机监控终端和下位机控制节点，监控终端负责设置各车灯的工作参数和显示车灯的工作状态；控制节点采用基于Cortex—M3内核的嵌入式微处理器LM3S2965为核心，将实时操作系统μCOS-II植入其中，提高系统的实时性和稳定性，同时将我国自主研发的iCAN协议应用到系统中，从而实现对车灯的网络化监控。结果表明，系统最多可对63个车灯进行实时的电气参数检测与控制。具有较高的可靠性。

In order to insure the quality reliability of the car light, this paper put forward a design scheme of embedded car light controlling and electric testing system. The system include upper computer monitoring terminal and lower computer controlling node, the monitoring terminal is responsible for settting the running parameter of every car light and displaying the working status of car lights ; The controlling node used LM3S2965 as core, which was embedded microprocessor with Cortex- M3 core, then transplant the real-time operating system μC/OS- II in it, and increase the stability and real-time of the system, at the same time, the iCAN protocol which was researched and developed by our country is applied to the system to achieve the networking monitoring of the car light. The result shows that the system can test and control 63 car lights at most in real time, and have higher reliability.
