Research on Automatic Test Method of Radio Block Center Based on Script Technology

Abstract

Radio Block Center (RBC) is the wayside core equipment of high-speed railway train control system, which is the key to achieve the safe operation of trains. In order to ensure the correctness of the function of RBC equipment and to send movement authority information to the train correctly, it is necessary to verify the consistency of RBC function with the RBC requirement specification. Therefore, the RBC functional testing is the basis and key to ensure the safety of train operation. The execution of testing cases has a great impact on testing efficiency. How to automatically execute testing cases and fully cover the system specifications is the key issue of RBC functional testing. Aiming at the shortcomings of traditional RBC functional testing, such as low efficiency, long time consuming, huge workload, and low accuracy of fault simulation, by studying the preparation of automatic test environment and the execution of automatic testing cases, this paper proposes a script based automatic functional testing method, and takes the RBC functional testing as an example to verify the correctness and effectiveness of this method. The practical application shows that the description ability of the test script language and the automatic testing environment meet the RBC testing requirements. The timeliness and the safety of RBC functional testing can be improved by using this method.
