摘　　要：为满足大秦铁路日益增长的业务需求,基于大秦线运输组织特点和CTC3.0系统数据流原理,结合现场故障排查流程,详细分析调度集中系统中心站场表示信息丢失的原因,最终确定在大秦线数据量瞬时较大的情况下,系统通信组件将数据分成包头、包尾2次发送,导致助调工作站数据解析效率降低,引发中心站场表示信息丢失。为此提出采用合并发送数据帧的方式,提高系统的数据处理能力和整体性能,有效解决中心站场表示信息丢失问题;提出降低数据负载和建立预警机制等策略,进一步提升调度集中系统的稳定性和可靠性。经现场验证,该方法可有效提升大秦铁路的运输效率,为类似重载铁路调度集中系统功能优化提供参考。To meet the growing operational demands of the Datong—Qinhuangdao Railway,based on the transportation organization characteristics of Datong—Qinhuangdao Railway and the data flow principles of the CTC3.0 system,and combined with the procedure of on-site fault diagnosis,a detailed analysis was conducted on the reasons for the loss of central station and yard indication information of the centralized traffic control system.It was ultimately determined that under circumstances of instantaneous large data volume on the Datong—Qinhuangdao Railway,the system's communication components divided the data into header and footer packets for transmission,leading to a decrease in data parsing efficiency of auxiliary dispatching workstations and resulting in the loss of indication information at the central station and yard.To address this,a method of merging transmitted data frames was proposed to enhance the system's data processing capability and overall performance,effectively resolving the problem of indication information loss at the central station and yard.Additionally,strategies such as reducing data payloads and establishing early warning mechanisms were proposed to further enhance the stability and reliability of the centralized traffic control system.Field verification confirmed the effectiveness of this method in improving transportation efficiency on the Datong—Qinhuangdao Railway and provides insights for similar optimizing functionalities of centralized traffic control system of heavy haul railways.
