在CTCS-2级列控系统中,车载ATP控制着列车运行速度,保证列车运行安全,因此需要对车载ATP功能进行全面严格地测试.为了提高测试效率,降低测试人员的工作强度,提高测试结果的准确度,本文设计了一种基于Tcl脚本语言的CTCS-2级车载ATP自动测试平台,首先介绍了该测试平台的系统结构,其次设计了测试案例脚本与车载ATP自动交互信息的三种方式,最后说明了轨道区段脚本、应答器脚本和测试案例脚本的设计方法和使用方法.通过实验证明该平台结构合理,脚本设计和使用方法正确,测试案例脚本与车栽ATP自动交互信息的方式能够实现对车载ATP功能的自动测试,是一种高效的、先进的CTCS-2级车栽ATP自动测试平台.%In CTCS-2 train control system,ATP controls the train speed and ensures the train safety,so it needs to test ATP functions comprehensively and vigorously.In order to improve test efficiency,reduce the staff strength and improve the accuracy of test results,an automatic CTCS-2 ATP test platform is designed based on the tool command language.Firstly,the system structure of the test platform is introduced.Secondly,three ways of exchanging information between the test case script and ATP are designed.Finally,the designing and using method of track section script,balise script and test case script are introduced.Experiments show that the test platform structure is reasonable,the method of designing and using script is correct,and the automatic test for ATP functions can be achieved by the way of exchanging information between the test case script and ATP.This platform can meet the test requirements,and it is a high efficient and advanced CTCS-2 ATP test platform.
