基于通信的列车运行控制系统测试研究

针对城市轨道交通基于通信的列车运行控制(CBTC,Communication Based Train Control)系统互联互通测试规范的要求,研究CBTC系统的测试方法。文章介绍了CBTC系统测试平台、测试流程和测试案例的开发,并以CBTC系统运行过程中的区域控制器(ZC,Zone Controller)移交场景为例,以车载控制设备(VOBC,Vehicle On Board Controller)为被测对象,提取测试需求,编写测试案例。测试系统从外围设备模拟系统中获得设备的状态信息,与脚本中预期的反馈结果进行比对。测试结果验证了CBTC系统测试方法的可用性。

Test method of communication based train control system

According to the requirements of Communication Based Train Control （CBTC）system for urban rail transit test specification of interoperability, the test method of CBTC system is studied. This paper introduced the test platform, test flow and development of test cases of CBTC system, took the handover scenario of Zone Controller (ZC) during the operation of CBTC system as an example, and took Vehicle on Board Controller (VOBC) as the tested object, extracted the test requirements and wrote the test case. The test system obtained the state information of the equipment from the peripheral equipment simulation system, compared to the expected feedback results in the script. The test results verify the availability of CBTC system test method.
