Research on Automatic Test Method of Communication Status Between TSRS and External Systems
In the new train control system,it is necessary to conduct strict indoor tests on the logical channel and application layer connection status between TSRS and external systems in order to ensure their normal communication connection in the case of partial logical channel failure.This paper proposes an automatic test method and device of the communication status between TSRS and its external systems.The device obtains the IP addresses of TSRS and the external system under test by reading the original input data,and then uses the decision table method to arrange and combine multiple situations to generate a full-traversal test sequence of the logical channel status and application layer connection status of each external system,and then automatically executes the test and records the test results through the IP automatic modification function of the device,and then judges them according to the communication principle of TSRS and the external systems,automatically outputs the expected results,and finally compares the automatic test results with the expected results to generate a final test result table.This method can avoid the omission of test scenarios,ensure the correctness of test results,and quickly improve the test efficiency.
