摘　　要：铁路信号系统的测试平台若使用硬件设备进行轨旁信号系统仿真,会存在成本高、搭建难度大等问题。为此,设计一种脱离硬件限制、完全基于软件实现的轨旁设备仿真系统。该仿真系统通过接口模块实现与信号系统的信息交互,将每一种轨旁设备响应信号系统驱动命令的控制逻辑抽象为“驱动-采集”的映射关系,将轨旁设备具有自动恢复机制的自复式按钮的采集逻辑抽象为“采集-采集”的映射关系;并在匹配关系文件中采用可扩展标记语言定义这些映射关系,通过响应信号系统驱动命令来仿真轨旁设备动作逻辑,通过延时处理自复式按钮的采集状态来仿真设备的自动恢复。系统考虑了设备动作过程中的动作时间和通信延时,使用锁定和解锁采集码位的方法实现各类故障仿真。该轨旁设备仿真系统已多次用于信号系统的测试平台或教学仿真平台的搭建,可完整覆盖轨旁设备的动作逻辑和现场场景,使用效果良好。If the test platform of railway signal system uses hardware equipment to simulate wayside signal system,it will face the problems of high cost and great difficulty in building.Therefore,the wayside equipment simulation system that is independent of hardware limitations and completely implemented based on software is designed.This simulation system realizes data interaction with the signal system through the interface module,abstracts the control logic of each type of wayside equipment responding to the driving commands of the signal system as the mapping relationship of“drive-acquisition”,and abstracts the acquisition logic of the self-resetting button with an automatic recovery mechanism of the wayside equipment as the mapping relationship of“acquisition-acquisition”.And in the matching relationship file,these mapping relationships are defined using extensible markup language.The action logic of wayside equipment is simulated by responding to the drive commands of the signal system,and the automatic recovery of the equipment is simulated by processing the acquisition status of the self-resetting button with delay.The system considers the action time and communication delay in the process of equipment action,and uses the method of locking and unlocking the acquisition code points to realize various fault simulation.The wayside equipment simulation system has been used in the test platform of signal system or to build teaching simulation platform for many times,which can completely cover the action logic and scene of wayside equipment,and the use effect is good.
