STP系统列车定位方法研究

Train Positioning Methods of STP System

基于无线调车机车信号和监控系统(STP)的系统结构,分析其特点及安全等级;将调车作业划分为9个典型应用场景,分析各应用场景下定位功能的不同特点;探讨STP系统定位功能在适用安全等级下的组合式实现,并给出2种定位方法的状态机模型。尤其在重点场景对机车和车列的相对位置进行研究,给出标签化处理的自动机模型,并阐述机车位置坐标丢失后STP系统的故障处理方式。

Based on the system structure of wireless shunting locomotive signaling and monitoring system(STP),this paper looks at the characteristics and safety levels of the system.It divides shunting operations into 9 typical application scenarios,and looks into the different characteristics of positioning functions under different application scenarios.It proposes the combined implementation of STP system positioning function under applicable safety level,and the state machine models of two positioning methods.In particular,it looks into the relative location of locomotives and trains in key scenes,offers the automata models of labelling processing,and elaborates on the failure treatment method of STP system after it loses locomotive position coordinates.
