中文摘要：
应用基于功能特征的测试案例生成方法,研究了无线闭塞中心的功能结构,提取了无线闭塞中心的功能特征,得到了无线闭塞中心的功能特征列表。针对无线闭塞中心的每个功能特征,编制了测试案例,将测试案例串联成电子化的测试序列。根据中国高速铁路列车运行控制系统的规范和要求,构建了无线闭塞中心的仿真测试平台,编写了试验步骤和XML程序文件。在无线闭塞中心测试平台上,测试了包含注册与启动、行车许可、停车与注销、通信网络故障、RBC切换5个运行功能的3个测试序列。测试结果表明：在常温常压下,列车速度低于350 km.h-1且仅有一趟列车运行的条件下,无线闭塞中心可不间断工作至少90 min,功能正常。可见,方法有效。
英文摘要：
Test case generation method based on function features was used,the function structure of radio block center（RBC） was studied,the function features of RBC were extracted,and the feature list of RBC was obtained.Aiming at the each feature of RBC,test cases were compiled and serially combined to electronic test sequence.On the basis of standards and requirements of running control system for China high-speed train,RBC test platform was established,and test step and XML program document was written.With RBC test platform,the three test sequences of five running features containing registration and start-up,driving permission,parking and cancellation,communication network fault and RBC switching.Test result shows that under room temperature and atmospheric pressure,while there is only one train and its speed is less than 350 km·h-1,the uninterrupted working time of RBC is more than 90 min,and the function can be kept well.So,the proposed method is effective.12 tabs,7 figs,18 refs.
