摘　　要：STP系统采用无线数传方式实现车地通信,因编组站地形多样,电磁环境复杂,影响无线通信因素较多,使系统的通信距离和通信质量受到很大限制。针对目前编组站STP系统在无线通信应用中存在的问题进行分析,并结合现场实际应用,探讨通过干线放大器、光纤直放站和异频电台方式实现无线通信的解决方案。研究解决编组站车地无线通信质量不佳造成的机车退网、信号消失、距离丢失等问题,保证铁路编组站STP系统的使用安全和高效。STP system adopts wireless data transmission to realize vehicle-ground communication.Due to the variety of terrain and complex electromagnetic environment of marshalling station,there are many factors affecting wireless communication,so the communication distance and quality of the system are greatly limited.This paper analyzes the problems existing in the wireless communication application of STP system at marshalling station,and discusses the solution of realizing wireless communication by means of trunk amplifier,optical fiber repeater and different-frequency radio in combination with on-site practical application.It also takes research on the solutions of solving the problems such as locomotive leaving the network,signal disappearing and distance loss caused by the poor wireless communication quality in the marshalling station,and ensure the safety and efficiency of STP system in the railway marshalling station.
