Interactive simulation test method of interval occupancy check function between tcc and tsrs

Abstract

The present invention relates to an interactive simulation testing method for checking function of interval occupancy between TCC and TSRS. The specific steps include: S1: determine all state transition scenarios according to an interface file; S2: draw a TCC interval to be tested according to all state transition scenarios State machine diagram of the occupancy check function; S3: Use the simulated TSRS to set and test all state transition scenarios; S4: If the test result of S3 is consistent with the state machine diagram, the test passes, otherwise, the test fails. Compared with the prior art, the present invention has the advantages of high efficiency and high accuracy.

Description

technical field [0001] The invention relates to the field of train detection and maintenance, in particular to an interactive simulation test method for checking the function of interval occupancy between TCC and TSRS. Background technique [0002] In my country's new era of intelligent railways, the ATO function of automatic train driving is proposed to reduce the labor intensity of drivers. ATO ground core equipment includes temporary speed limit server TSRS, train control center TCC and dispatch centralized system (CTC). The space interval system is implemented for train operation to ensure a safe distance between the two trains. At present, in order to reduce the impact of running on the track circuit failure or poor branching, the C2, For the C3 line, the TCC adds a function module to implement the interval occupancy logic check, and at the same time, adapts the interface device TSRS. After the software is upgraded, the interface between TCC and TSRS needs to be tested...

Problems solved by technology

When directly using the interface file and TCC-TSRS real interface environment for testing, firstly, the interface file is directly converted into a test scenario, which may easily lead to incomplete test scenarios; secondly, since the real device can only send or receive normal messages, it will not send illegal message, so the real interface environment can complete the test with fewer scenarios and a smaller scope; then, using the real interface environment test, the speed of setting up the test scene is slow and the efficiency is low; finally, because the real interface environment has inflexible operation and interactive message Unintuitive and other deficiencies, it is not easy for test or debugging personnel to understand the interaction function between devices
