Abstract: This paper analyzes the operation scenarios of train integrity related functions at the system level, utilizes the sequence diagram and flow chart to model the information interaction and processing logic among onboard equipment, EOT equipment and wayside equipment, and designs the test cases for the normal scenario, the fault scenario with a single vehicle in operation and the fault scenario with two trains in tracking state. The functions related to train integrity and the feasibility of test cases are verified through a laboratory half-physical simulation test platform. The proposed design method for test cases has important reference significance for the formulation of the test scheme for the train integrity related functions in the new train control system.
