摘　　要：在GSM-R覆盖的线路上,无线进路预告是调度集中系统(CTC)的重要功能,无线进路预告的准确发送,对铁路的高效、安全、可靠运输具有重要意义。通过分析无线进路预告发送的应用现状以及容易造成进路预告错发的因素及目前的处理机制,围绕铁路局集团公司间车次号传递、重复车次号、车次号异常注销等特殊场景,结合2个实际案例,详细描述进路预告的发送过程及CTC系统为防止错发所做的处理逻辑。针对现有防护机制下,重复车次号仍存在无线进路预告错误发送的可能,给出优化方案。通过CTC系统与GSM-R系统相结合,无线进路预告提前向列车发送行车信息,能够有效提高列车的运行效率、增强行车安全性,优化调度资源。On the lines equipped with GSM-R,wireless route advance notice is an important function of the centralized traffic control(CTC)system.The accurate transmission of wireless route advance notice is of great significance for efficient,safe and reliable railway transport.By analyzing the application status quo of wireless route advance notice transmission,the factors that may easily cause incorrect wireless route advance notice transmission and the current processing mechanism,this paper focuses on special scenarios such as train number data transmission between different regional groups,repeated train number data and abnormal cancellation of train number data,and combining with 2 actual cases,describes the transmission process of route advance notice in detail,and analyzes the logic of processing by the CTC system to prevent incorrect transmission.Given that there remains a possibility of incorrect wireless route advance notice transmission for repeated train number data under the existing protection mechanism,this paper proposes a scheme for optimization.By integrating the CTC system with the GSM-R system,train operation information can be sent to the train in advance through the wireless route advance notice,which can effectively improve the train operation efficiency,enhance train operation safety and optimize dispatching resources.
