摘要: 针对TDCS/CTC系统基于MQ组件进行局间信息交互中存在单网故障或单点MQ队列中断引起局间站场信息显示不一致、局间调度命令交互异常等故障。通过使用TCP/IP取代MQ与优化既有单点MQ连接的方式开展针对局间交互方式优化探究,有效提高局间交互信息的稳定性。

Abstract: During the information exchange between Railway Bureaus based on the MQ component in the TDCS/CTC System, a single-network fault or a single-point MQ queue interruption may cause inconsistent display of information on stations and yards between Bureaus and abnormal exchange of inter-Bureau dispatching commands. By using TCP/IP to replace MQ and optimize the existing single-point MQ connection, this paper carries out research on the optimization of inter-Bureau interaction modes to effectively improve the stability of inter-Bureau interaction information.

Key words: Centralized Traffic Control System, network structure, redundant data transmission
