基于北斗卫星定位系统的地铁工程车车载调车防护软件设计

Design of Onboard Shunting Protection Software for Metro Engineering Vehicles Based on BeiDou Satellite Positioning System

目前,地铁工程车作业时依靠乘务员目视行车,在复杂的作业场景中存在冒进信号、超速运行和挤岔等安全问题。对此,文章基于北斗卫星定位系统提出一种地铁工程车安全防护系统用调车防护软件,并详细阐述了其功能设计、软件接口、模式转换和防护方式。该调防软件使用安全计算机平台工具,采用模块化设计,并综合运用了北斗卫星定位系统、信标定位系统和计算机联锁系统以及二叉树理论,实现了对地铁工程车调车作业时的精准防护,能有效解决工程车作业过程中的安全隐患,提高了地铁调车作业的安全性。2020年底,该调车防护软件在广州地铁5号线以及鱼珠车辆段进行了运用试验,结果显示,其能够及时地对冒进信号、超速运行和挤岔等情况进行防护,满足用户对调车作业的安全防护要求。

At present,metro engineering vehicles rely on visual driving by the driver,and there are safety problems such as rushing cross signals,overspeed and impacting switch in complex operation scenarios.This paper proposes a piece of shunting protection software based on the BeiDou satellite positioning system,and expounds its function design,software interface,mode conversion and protection method in detail.The shunting protection software uses safety computer platform tools,adopts modular design,and makes comprehensive use of the BeiDou satellite positioning system,beacon positioning system,computer-based interlocking system and binary tree theory to realize precise protection of metro engineering vehicles in shunting operation,effectively solve the safety risks in the operation process,and improve the safety of the metro engineering vehicles in shunting operation.At the end of 2020,the shunting protection software was tested in Guangzhou Metro Line 5 and Yuzhu Rolling Stock Depot.The results show that it can timely protect against rushing cross signals,overspeed and impacting switch,and meet the safety protection requirements of users for shunting operation.
