摘　　要：为了验证高速铁路移动闭塞系统(Moving Automatic System,简称MAS)结构完整性、控制逻辑正确性以及列车追踪运行的动态控制过程,利用着色Petri网建立移动闭塞条件下高速列车两车追踪运行控制过程的模型,采用相对制动方式下基于追踪效率最高的区间追踪间隔原理,设计了控制策略决策模块,模拟列车牵引加速、惰行以及减速运行等控制过程,研究MA更新周期变化对列车追踪控制的影响。仿真结果表明所建立的模型可以有效描述MAS下高速列车追踪运行控制过程,且MA更新的周期越小,列车的行为控制越灵敏,达到预期控制目标所需要的时间更短,满足行车安全性、高效性要求。仿真结果将为MAS在高速铁路中的实际应用提供理论指导。In order to verify the structural integrity and correctness of the control logics and the dynamic control processes of train tracking operation of high-speed railway Moving Automatic System, the Colored Petri Nets is used to establish a model of the control processes of two trains tracing one after another. The theory of relative braking method and the highest tracing efficiency method are employed to design the control strategy decision module to simulate train acceleration, coasting and braking processes and to study the influence on the train tracing control generated by the changes of MA update cycle. Simulation results show that the model established in this paper can effectively describe the control processes of train tracking operation under the MAS condition and the smaller the MA update cycle, the more sensitive the train movement control, which meet the requirements for less time, safe and efficient operation. The results of simulation may serve for future application of MAS in high-speed railway operations.
