汽车LIN总线数据监视器的设计与实现

On the Design and Implementation of LIN-bus Data Monitor

LIN(Local Interconnect Network)总线是一种在汽车电子控制系统中已被普遍采用的低速、低成本的串行通讯网络。为了对基于LIN总线的分布式电子系统进行LIN总线信号测试和数据分析,对ELM633芯片的硬件电路进行设计,运用VC++软件编制实用软件,开发了操作简便的汽车LIN总线数据监视设备,由此可以成功实现对车辆LIN总线上全部信号的捕捉和采集。它的使用对LIN总线信号测试、数据分析和相关教学培训等工作具有一定的应用价值。

LIN （ Local Interconnect Network ） bus is a low - speed, low - cost serial communication network which has been widely used in automobile electronic control system. In order to test and analyze the signal that is based on LIN bus distributed electronic systems, the author has developed easy - operated automotive LIN bus data monitoring equipment by the designing of ELM633 chip hardware circuit and the programming of applying software via using VC ＋ ＋ software, so the capture and collection of LIN bus signal can be successfully a- chieved, which has highly valuable application in LIN bus signal testing, data analysis and related teaching and training work.
