通用车载总线测试系统的设计与实现

Design and Application of General Vehicle Bus Testing and System

针对目前车载总线的测试技术中存在的不足和存在测试类型缺项问题,提出了基于总线传输数据波形的通用车载串行总线测试方案,设计了通用车载串行总线测试系统,可完成多种车载总线物理层电气性能和数据链路层传输性能的综合测试,便于对总线的故障进行查找和定位,为展开针对性的维修提供了可靠依据。

Aiming to the problems that the current vehicle bus test technology just realizes the test of DLL and the test equipment is not universal,this paper brings forward a universal test method to the vehicle bus based on Data Frame Collecting technology and Software Decoding technology,designs the physical layer test system to the universal vehicle bus.It’s convenient to locate the fault and provide solid judgments for maintenance.
