| 摘 要： | 为了解决现代汽车越来越复杂的电气系统的通讯问题,采用了CAN串行总线实现多路传输,组成汽车电子网络.CAN采用多主工作方式,节点之间不分主从,通信方式灵活,可实现点对点、一点对多点及广播式传输数据.用美国NI公司的LabVIEW开发系统应用程序,在Windows平台上,通过NI的PCMCIA接口形式的CAN卡采集CAN总线数据.CAN 2.0 B规范CAN总线最大通讯速率可以达到1 Mb/s,对CAN总线采集到的数据,可以用LabVIEW编程的虚拟示波器显示动态波形,实现对整车信号的在线实时测量与故障诊断.

| Abstract: | To solve the complex communication problems of electrical system in modern automobile ,a multi -circuit transmission of CAN serial port communication is used and by which an automobile electronic system network is composed of CAN works in multi - master mode,and communication mode is flexible. It may be point to point or one point to more points,and data transmission in broadcast mode. Under Windows with LabVIEW of NI company,a system software is developed which realizes the data acquisition of CAN bus through PCMCLA interface. These Bus data comes into dynamic curve waves in a virtual osillscope ,and then realizes a real - time measurement online and fault diagnosis of complete vehicle signals. |
