摘　　要：本文在对调度集中系统车次追踪问题进行分析的基础上,以提高车次号的准确性为目标,结合有限自动机理论,利用抖动抑制算法降低车站信号状态可能出现的抖动干扰,提出了一种基于车站简单对象并具有容错性质的车次追踪模型,并对模型的运行机制进行了论述。该模型已在实际系统中得到了应用,并取得了良好的效果。Through the analysis of the train tracing problem of CTC System,this paper abandoned the traditional tracing model based on the route connection.Taking the accuracy of train number as optimization goal and combining with finite automata theory,the paper presented a fault tolerant model of Train Tracing System which was based on the simple station elements.A filter algorithm was introduced to reduce the dither noise caused by signal state.Also the operating mechanism was discussed.This model has been used in the CTC System and attained satisfying results.
