光纤直放站+时延模块技术在大型铁路编组站中的应用研究

利用GSM-R实现调车业务,有利于克服传统400MHz无线通信的诸多缺点,实现话音、调车指令同时传输,调车作业单无纸化传送,满足编组站综合自动化的需要,提高劳动效率,保证安全生产。针对新丰镇编组站地区特殊的线路情况,提出采用光纤直放站+时延模块技术对编组站进行场强覆盖。通过无线网络规划、模拟测试等手段,有效解决新丰镇编组站和郑西客运专线间的频率干扰、多径干扰问题。

Application Research of Fiber Optic Repeater plus Delay Module Technology in Large-scale Railway Marshalling Station

Using GSM-R technology in railway shunting operation can be useful to overcome many shortcomings in traditional 400 MHz wireless communication,achieve simultaneous transmission of both the speech sound and railway shunting instruction,fulfill paperless transmission of railway shunting work ticket,meet the requirement of comprehensive automation in railway marshaling station,improve work efficiency and ensure the safety in production.This paper,focusing on the special situation of railway lines in the Xinfengzhen marshalling station,proposed that there should be the fiber optic repeater plus delay module technology used for field intensity coverage in this marshaling station.It is proved by practice that the problems of frequency interference and multi-pass interference between the Xinfengzhen marshalling station and the Zhengzhou- Xi'an railway passenger dedicated line can be solved by using wireless network planning,simulation test and other relevant methods.
