摘要
在分析目前机上电缆传统测试方法所存在的弊端的基础上,针对当前自动测试系统未解决的机上电缆测试问题,提出了一种基于传输线理论的机上电缆断点位置测试方法,给出了断点定位仪硬件电路设计和误差分析方法,并对误差分析得到的相关参数进行了仿真实验,根据仿真结果,给出断点定位仪的优化方法,可实现对机上电缆断点的精准定位。
After the analysis of the disadvantages of the traditional test methods about the on-vehicle cables and in view of the problem that the on-vehicle cable test has not been solved in the current ATS, a test method of on-vehicle cable faultpoint locator based on the theory of transmission line was put forward. At the same time, the hardware circuit design of faultpoint locator and the method of error analysis were given. A simulation experiment was done with parameters provided by error analysis. According to the results of the simulation, the better way was got to design the locator. As a result, accurate positioning of on-vehicle cable breakpoint was implemented.
