摘要

Automatic Train Protection (ATP) System is the key of Urban Track Communication Signal System; it plays an important role in promoting the safety and efficiency of train's running. With the background of developing the ATP System Simulation, focusing on the track circuit system simulation, this paper gives some research on the system simulation software choosing, compares this digital simulation system with other simulation systems before, presents its advantages of the system simulation based on MATLAB. By testing the mathematic model with some analogical sets, the output data of digital simulation fit well with those of the analogical experiments. Then the conclusion can be drawn that the model is correct and can be put into practice instead of the analogical sets or the entities of a track circuit systems. Further more the feasibility and correctness of track circuit digital system simulation based on MARLAB can be provided.
