Engineering Application Optimization Scheme of CTC Route Notice Operation Mechanism

通过介绍CTC进路预告的运行机制,着重说明进路预告ID生成原理、进路预告内容正确性检查、进路预告发送后的软件逻辑判断,以及基于铁路数字移动通信系统网络实现进路预告成功发送至机车的交互逻辑;对使用中发现的部分特殊案例进行针对性研究,重点对进路非正常出清后的预告取消、计划次序混乱下的预告取消、信号故障关闭时的预告取消、重复车次下的预告处理等4个问题进行详细分析、阐述,深入说明软件处理逻辑、人为操作因素、硬件条件、接口协议卡控等对进路预告功能的影响,提出实际、可行的优化方案;最后对优化方案进行实践应用,验证软件优化逻辑的正确性,解决对应问题。

Firstly,the operation mechanism of the CTC route notice is introduced,focusing on the generation principle of route notice ID,correctness check of route notice content and the software logical judgment after route notice transmission;the interactive logic fulfilling successful transmission of route notice to locomotives based on the GSM-R network is also emphasized.Then,a targeted study is conducted on some special cases found during use.Detailed analysis and explanation are conducted on four issues,i.e.notice cancellation after abnormal clearance of routes,notice cancellation under chaotic planning sequence,notice cancellation when fault-caused signals are closed,and notice handling under repeated train numbers.The impacts on the route notice function are described thoroughly in 4 aspects,i.e.software processing logic,human operation factors,hardware conditions,and interface protocol control.A practical and feasible optimization scheme is proposed.Finally,the optimization scheme is applied practically;the correctness of the software optimization logic is verified;the corresponding problems are solved.
