Research On The Automatic Analysis And Validation Methodology Of The CTCS-3on-board Equipment Test Results

The CTCS-3train control system has been widely applied on the high speed railways in China with speed above300km/h, to guarantee the safety and high efficiency of train operation, of which the on-board equipment is an important part. Therefore, it is necessary to carry out a series of testing to verify whether the on-board equipment can meet the system requirements specification of train control system. For the laboratory testing of the on-board equipment, the black-box testing method based on data driven mechanism is generally adopted. Due to the large amount of testing items and the complexity of the testing process, the work of analyzing and validating the testing results is time-consuming and tremendous. Therefore, it is necessary and meaningful to carry out the research on the automatic analysis and validation method of testing results.Some related researches have been done abroad and some tools are available, but the key techniques are yet to be publicized. Based on the laboratory testing platform for the CTCS-3on-board equipment established in Beijing Jiaotong University, this thesis focuses on the research on the method for automatic analysis and validation of the test results, and the development of a software tool. The main works of this thesis are as follows.1. To address the disadvantages of manual analysis and validation of the testing results, the automatic method is proposed.2. Based on the structure and function of the on-board equipment, and the working principle of the laboratory testing platform, the method for automatic analysis of the test results is proposed to realize the acquirement, pretreatment, parsing and timely display of the test results.3. Due to the large amount of test results data, the different contents and methods for validation in each test step, it is difficult to realize the automatic validation. A solution is proposed to solve the problem. Firstly, the expected results are summarized from all the test cases; secondly, the functions for validating each test case are designed; thirdly, the test results are further screened from the corresponding data tables, and the proper validation function is called to realize the automatic validation.4. An automatic analysis and validation tool is designed under Visual Studio2010development platform, with its major functions implemented.
