Abstract: Communication coding ZPW-2000 series track circuit has been widely used in high-speed railway, and its interface object with external equipment mainly involves train operation control (hereinafter referred to as: train control) center. At present, for the overall function test of track circuit equipment, there is only a simple test environment that can simply simulate the coding function of the train control center, and there is a lack of an integrated test environment that can simulate all interface functions. This paper analyzed the interface requirements between the communication coded ZPW-2000 track circuit and the train control center, designed a simulation test platform that could simulate the corresponding interface functions, and applied it to the research and development and testing of the communication coded ZPW-2000 track circuit, which not only reduced the cost of the test environment, but also completed the test work more flexibly, conveniently, efficiently and automatically.
