调度集中系统车次号技术的研究

Research on Train Number Technique for Centralized Traffi c Control System

列车车次号是调度集中系统实现调度指挥、列车运行追踪、自动采点、自动排列进路、无线进路预告和无线调度命令的重要基础信息,应保证及时、准确无误。基于对CTC车次号技术的研究,分析了车次号的显示、车次窗的设置、车次号的来源及优先级、数据结构及数据流和车次号的工作原理,提出了优化车次号优先级的建议,解决跨局折返且不同设备供应商间车次跟踪问题,有效避免车次号跟踪错误,提高车次跟踪的准确性。

Train number is an important basic information for Centralized Traffi c Control System to realize dispatching,train running tracking,automatic time collection,automatic arrangement of routes,wireless route announcement and wireless dispatching commands,which shall be timely and accurate.Based on research on train number technique for CTC,this paper analyzes the display of train number,the setting of train number window,the source and priority of train number,the data structure and data fl ow of train number,and the working principle of train number,and puts forward a proposal for optimizing the priority of train number,which solves the problem of cross-offi ce turn-back and train number tracking among different equipment suppliers,effectively avoids the error of train number tracking and improves the accuracy of train number tracking.
