Abstract: Train running simulation of PDL should possess higher precision in terms of the characteristics as high speed and high precision of passenger dedicated line (PDL). The simulation initialization is one of the key factors to improve precision of train running simulation. This paper proposes a new accurate simulation initialization method based on train performance calculation and rules-reasoning. The main process of the simulation initialization is designed first, and the train’s absolute position is abstracted in the signaling system. Then it put forward plus and minus rules collection, and provides reasoning mechanism. On the basis of the railway organization simulation system of PDL, this paper takes the under-constructing Beijing-Tianjin Passenger Dedicated Railway Line as background. Simulation experiments are respectively carried out using traditional way and accurate simulation initialization method in four-aspect fixed block signaling system and quasi-moving block signaling system. The results indicate that train running simulation precision ADT can be reduced by 23%.

摘要： 客运专线具有高速度、高精度的特点，对列车运行仿真的精度提出较高的要求。系统初始映像的质量是影响列车运行仿真精度的关键因素。提出了基于牵引计算和规则集推理的精确系统初始映像方法。首先设计了初始映像的主体流程，然后对列车在信号系统中的绝对位置进行抽象，建立了正向规则集和反向规则集，并给出了推理机制。最后在自主设计开发的客运专线列车运行组织仿真系统上，以正在建设的北京到天津客运专线为背景，分别应用传统的和精确的初始映像方法在四显示固定闭塞和准移动闭塞下进行仿真。仿真结果表明，列车运行仿真精度指标－平均偏离时分能够降低23％。
