CBTC系统中计轴设备布置方案研究

Research on Arrangement Scheme of Axle-counting Equipments in CBTC System

CBTC系统中计轴设备用于检查轨道区段空闲与占用状态,通常一条城轨线路中需要设置上百个计轴设备。为了科学、高效、快捷地布置这些计轴设备,文章提出了在站台区域、岔区、保护区段、转换轨、折返轨、联锁区分界点、区间以及场段等8个场景下的计轴设备布置方案。该方案从工程项目实际出发,描述了各计轴设备的用途,详细分析了其布置原则。在长沙轨道交通4号线的应用结果表明,该方案能准确完成轨道状态检查,并能辅助列车安全高效地运行。

Axle-counting equipments in CBTC system are used to check the idle and occupied status of track section.One urban rail transit line needs to set up more than 100 axle-counting equipments.In order to arrange axle-counting equipments scientifically,efficiently and quickly,this paper put forward a layout arrangement scheme of axle-counting equipments under 8 scenes,including platform area,turnout area,protection section,transfer track,turn back track,interlocking boundary point,section and depot.Starting from the actual situation of the project,this scheme describes the uses of axle-counting equipments,and analyzes the layout principle of axle-counting equipments in detail.The application results in Changsha rail transit line 4 verify that track states can be accurately inspected,and safe and efficient operation of train can be assisted by the scheme.
