Abstract:

Computer interlocking system is a key subsystem of railway transportation system that requires high safety and reliability. For a long time, fully covering the test of railway signal interlocking system was difficult because of the large amount of data. This paper focuses the research and development on a rule-driven automated platform that integrates expert experience into automatic testing and can generate test scripts based on rules to cover all signal devices. It canalso protract track map and perform scripts in a single batch. Test results against an interlocking system of a special line show that the platform is especially suitable for medium- and large-scale station testing, and can be easily extended to the testing of other security systems.

Key words: interlocking system, rules driver, automatic testing
