Abstract: During the manual functional testing for the onboard Automatic Train Protection (ATP) equipment in a semi-physical test environment, there are such problems as low efficiency, complex operations, high labor costs, poor visibility and challenges in test case design and maintenance. This paper presents the design and implementation of a general automatic test platform for onboard ATP based on an in-depth function analysis of various ATP products. A general script language is designed and developed for onboard ATP testing to convert the test cases into specific collections of script instructions based on the train location and communication message. An extensible interface platform is designed and developed for hardware components, and is combined with the robotic arm control and DMI image recognition units to simulate the external input signals and driver operations for ATP. A general communication protocol between various devices is designed for software components, and a comprehensive tool set covering script parsing and execution, communication protocol conversion and test process management is developed to enable the automatic control of the testing process. The actual engineering application demonstrates the proposed general automatic test platform for onboard ATP can reduce development costs, enhance test productivity, and offer substantial practical value.
