CBTC系统中车载设备功能实现

摘要

With the development of urban railway transportation, CBTC system which is a new train control system is applied to constructions of urban railway transportation. This paper takes ALSTOM URBALIS TM CBTC system which is used in subway Fang Shan line as an example. This paper introduces the definition and structure of CBTC system, analyses and discusses the theories about the realization of onboard equipment’s functions. Based on Fang Shan Line project, this paper designs the test program of onboard equipment’s main by using White-box testing methods, generates and analyses test cases. In testing, the testers observe the changes in key variables, verify the realization of onboard equipment’s functions.%随着城市轨道交通进入了高速发展时期,新一代的列车控制CBTC系统被运用到城市轨道交通的建设中。本文以北京地铁房山线采用的阿尔斯通URBALISTMCBTC系统为例。文章主要对CBTC系统的定义和结构进行介绍,并对其车载设备的功能实现理论进行分析和探讨。基于房山线工程,文章使用白盒测试方法对车载设备主程序测试方案进行设计,对生成测试用例进行分析。在进行测试中,测试人员观察关键变量的变化,对车载设备的功能实现进行验证。
