In order to solve the problems of incomplete interlocking test and incomplete test process, and to make up for the management loophole of completely relying on the laboratory personnel to control the interlocking test quality, the computer interlocking input-output abstract model is established, and the status information of the on-site equipment in the model is input into the variables according to the items to be tested in the interlocking relationship checklist of the station. The test case is constructed by the operation command input variables of the tester and the information display variables of the interlocking interface, and the one-to-one real-time feature matching is carried out by obtaining the relevant data such as the category, time and sequence of the manually clicked buttons, combined with the state change of the signal equipment and the display of the interlocking interface. After matching with the model test case table, the simulation manual automatically marks the matching items in the checklist, so as to achieve the effective supervision of the whole manual test process and improve the reliability of the interlocking test process.
