【摘要】 针对大型复杂装备线束网络在内外场、大修及改装等场合的测试维护需求,本文提出了一种基于 CAN 总线的分布式线束网络测试方案。该方案基于 CAN 总线的分布式系统设计,它提高了系统运行效率,大大减小了测试转接电缆长度,显著地减少了整个设备的体积和重量,使得大型复杂装备线束网络的测试维护变得方便、快捷。文章详细地介绍了基于 CAN 的分布式测试系统的组成结构,上位机和各测试节点的软、硬件设计方法及 CAN 总线网络应用层通讯协议的设计实现。更多还原

【Abstract】 This article puts forward a distributed test scheme based on CAN-bus to meet the test and maintenance demands of wiring harness network of large scale complicate equipment in the condition of infield,outfield,heavy repair and refit.It improves the use efficiency of system,decreases the length of cable,the cubage and weight of the equipment and makes the test and maintenance convenient and fast.This paper introduces in detail the composi- tion and framework of the distributed test system based on CAN-bus,the software and hardware design of upper computer and test nodes,and the communication protocol in network application layer.更多还原
