基于AdmiTest的CTCS-3级列控系统自动测试平台

The Automatic Testing Platform of CTCS-3 Level Train Control System Based on AdmiTest

根据CTCS-3级列控系统的特点,结合欧洲列车运行控制系统(ETCS)测试经验,研发基于通用测试平台AdmiTest的CTCS-3级列控系统自动测试平台CARSTool。CARSTool采用激励-反馈机制实现单系统或多系统的闭环测试,包含测试对象、仿真系统、链路、消息、激励、响应和测试序列等基本元素,具有线路工程数据配置、通信链路配置、站场线路配置、PI Object、仿真系统、列车运行仿真和自动测试序列7个功能模块。以郑西客运专线列控数据为例,采用CARSTool对CTCS-3级列控系统进行仿真测试。测试结果表明:通过规范化语法严格卡控测试步骤,根据CTCS-3级列控系统测试案例库以及激励-反馈信息判断测试项目的执行状态,CARSTool实现了测试计划、执行过程和测试结果的闭环处理;说明CARSTool能够实现CTCS-3级列控系统的自动测试。

Combining the testing experiences of Europe Train Control System （ETCS） and the features of CTCS-3 level train control system, the automatic testing platform CARSTool of CTCS-3 level train control system based on AdmiTest which is a general purpose testing platform has been developed. CARSTool uses stimulation-feedback mechanism to achieve closed-loop testing of single system or multiple systems. The basic elements of CARSTool include the test subject, simulated system, link, message, stimulation, response and test sequence. CARSTool has seven function modules, i.e. data configuration for line engineering, communication link configuration, line configuration for station and yard, PI Object, simulated system, train running simulation and automatic testing sequence. Train control data of Zhengzhou West Station were used for the simulation test of CTCS-3 level train control system by CARSTool. Test results show that, according to the test case library of CTCS-3, CARSTool which is an automatic testing platform based on AdmiTest has strictly controlled test steps through standardized syntax and used stimulationfeedback mechanism to judge the execution state of testing project. CARSTool has achieved the closed-loop processing of test plan, execution process and test result, which indicates that it can realize the automatic testing function for CTCS-3 level train control system.
