Lei Dou, Wudong Yang · 2019 CAA Symposium on Fault Detection, Supervision and Safety for Technical Processes (SAFEPROCESS) · 2019
In order to improve the current ATP (Automatic Train Protection, ATP) speed monitoring function test case incomplete problem, Taking the speed monitoring function of ATP in the TSM (Target Speed Monitor (TSM) area as the research object, the cause-effect graph is used to analyze the speed monitoring logic and design test cases. Firstly, functional logic of speed monitoring function of ATP in TSM area is analyzed. Then, the process of designing test cases for cause-effect graph is introduced. Finally, the cause-effect graph is utilized to design test cases for the speed monitoring function of ATP in TSM area. The results show that the test case designed by this method can improve the functionality of ATP speed monitoring function and the completeness of the safety test, thus ensuring the quality of ATP products.
