Broadband Mobile Communication Scheme of Shunting Train Protecting

无线调车机车信号和监控系统(STP)车地通信采用数传电台时,存在传输速率低、半双工通信机制带来的并发访问限制及扩容能力不足等问题,而采用GSM-R时数据传输速率低。分析利用宽带移动通信技术替代STP既有通信方式的可行性,重点研究该技术的组网方案与实施方案,并在实验室进行了接口和功能测试,测试结果满足应用需要。

When a data transfer radio is adopted for the train-ground communication of the shunting train protecting(STP),there are such problems as low transmission rate,limited concurrent access caused by halfduplex communication mechanism and insufficient capacity expansion,while the data transmission rate is low when GSM-R is used.The feasibility of replacing the existing STP communication mode with the broadband mobile communication technology is analysed,the networking scheme and implementation plan of this technology are emphatically studied,and the interface and functions are proved to meet the application requirements based on the lab tests.
