列控车载设备测速测距仿真测试方法与应用

Method and Application of Speed and Distance Measurement Simulation Test of CTCS Onboard Equipment

为解决集成测试方法无法对列控系统车载设备测速测距单元进行全面测试的问题,提出一种测速测距仿真测试方法,应用该方法可实现传感器状态设置、断线设置、空转打滑等多种工况的仿真测试和组合故障测试,有效提高测速测距系统的可靠性。

In order to solve the problem that the comprehensive test cannot be carried out for the speed and distance measurement unit of CTCS onboard equipment using the integrated test method,this paper proposes a speed and distance measurement simulation test method.The method can be applied to realize sensor state and disconnection setting,and perform simulation tests for idle running,sliding and other conditions and combined fault tests,effectively improving the reliability of speed and distance measurement system.
