Abstract: This simulation test platform was mainly used for the development of new track circuit system devices, which not only could greatly reduce the exorbitant test costs, improve the development efficiency, but also take the experiment of the subsystems about function, performance and reliability. This paper analyzed the communication between the train control center and track circuit subsystems, and then implemented the design algorithms, simulated secure communication between CTCS-3 train control center TCC and ZPW-2000A track circuit in a laboratory environment based on the CAN bus dual filter mode .
