轨道电路分路不良双计轴设备控制系统的实现

Bad shunting of track circuit of double axle counter equipment control system

通过对轨道电路分路不良问题的现状及相关技术的研究,实现了计轴设备控制系统,该系统严格遵守故障-安全的原则,系统不受道床条件影响,可以彻底解决分路不良问题,所采用的主要设备(包括控制设备)都放在室外,这样可以大大减少施工量与对既有线路的改造,室内的联锁设备与连线不需做任何修改。对系统架构、关键技术、软件实现及经济效益方面进行阐述。

This paper introduced the present situation and related technology research of the track circuit,and accounted the construction of the system,key technology,software to realize and economic benefit in detail.The double axle sensor control system strictly complied with the principle ＂fault lead safety＂.Without effect of rail bed conditions,the system can thoroughly solve the bad shunting of track circuit problem.The main devices（including control device） are placed outside,which can greatly reduce the reconstruction of rail line,no need to do any modification indoor joint line.
