Design of CBTC Real-Time Simulation System Based on FPGA

By analyzing the architecture of the Communication Based Train Control (CBTC) physical system and the functional logic of each subsystem, the model architecture of the CBTC simulation system is simplified, and the hardware resources and communication capacity occupied by the simulation system can be reduced. By establishing the digital simulation model of each subsystem, determining the hardware system selection and implementation method, a real-time simulation system of CBTC system based on Field-Programmable Gate Array (FPGA) is formed. By creating a virtual line with three stations and two sections and a virtual train to simulate the actual operating environment of the CBTC system, and inputting relevant parameters into the simulation system, the simulation system can correctly use the functional logic to control the train operation and related equipment actions, which shows that The function of the simulation system is verified. The CBTC simulation system constructed in this paper can provide an experimental verification environment for the model test of rail transit transportation equipment, and is of great significance to the research and development of key components or systems of rail transportation transportation equipment such as simulation, optimization, and verification.
