Research on LKJ2000 Automatic Identification Scheme of Siding Track Number

针对列车在接车/进站过程中因侧线股道号输入延误或错误易引发安全风险的问题,设计了一种列车安全辅助防护模块,基于LKJ2000实现侧线股道号的自动识别。通过预存车站综合站场图数据,为系统提供详尽的地理基础信息;利用RTK技术构建卫星差分基站,实现列车运行中的分米级高精度定位,极大提升了定位精度和实时性;引入先进加密技术,确保从车站计算机联锁系统或TDCS/CTC系统中接收的车站联锁数据的完整性和安全性;基于列车定位和联锁数据,结合LKJ车载基础数据文件,精准识别当前侧线股道号信息。该模块通过CAN总线将关键信息实时推送至LKJ2000,实现站场信息的同步可视化显示,为乘务员提供直观、全面的线路数据支持。经现场实车验证,该模块具有良好的兼容性和可靠性,也有效增强了LKJ2000系统的稳定性,进一步保障列车运行安全和运输效率。

The delay or error of the siding track number input tends to cause safety risks during train receiving or train's entering the station.To solve the problem,a train safety auxiliary protection module is designed to realize automatic identification of siding track numbers based on LKJ2000.By pre-storing the comprehensive station map data,the module provides detailed geographic basic information for the system.By leveraging on Real-Time Kinematic(RTK)technology to establish a satellite differential base station,it enables centimeter-level high-precision positioning during train operation and significantly enhances positioning accuracy and real-time performance.Additionally,advanced encryption technology is introduced to ensure the integrity and security of station interlocking data received from the station computer interlocking system or TDCS/CTC.Based on the train positioning and interlocking data and the LKJ on-board basic data file,the current siding track number information is accurately identified.The module pushes key information to the LKJ2000 in real time through CAN bus,enabling synchronized visual display of station information and providing intuitive and comprehensive line data support for the train crew.Rigorous on-site vehicle verification has demonstrated the good compatibility and reliability of the module,which effectively enhances the stability of the LKJ2000 system and significantly improves the safety of train operation as well as the overall efficiency of railway transportation.
