长大干线高速磁浮无线通信系统工程方案研究

Research on Engineering Scheme of Radio Communication System for Long Main Line With High Speed Maglev

针对时速600 km长大干线高速磁浮的运营特点及其对无线通信的需求,提出“38 GHz毫米波+数字移动无线通讯(Digital Mobile Radio,DMR)”的无线通信系统工程方案。采用38 GHz毫米波实现磁浮列车定位数据等实时安全数据的承载;采用DMR实现调度、客运和运维等语音通信;并且根据系统业务需求,38 GHz毫米波也可承载车载乘客信息系统、车载视频等大带宽业务。该方案既满足牵引供电及运控系统业务对实时性和可靠性的要求,又能在尽可能节省投资和考虑产业支撑的情况下,满足长大干线运营所需的调度、客运等语音通信需求。

According to the operation characteristics of high speed maglev of 600 km/h long main line and its demand for radio communication,an engineering scheme of"38 GHz millimeter wave plus DMR"radio communication system is proposed.38 GHz millimeter wave is used to carry realtime safety data such as maglev train positioning data;DMR is used to realize voice communication for dispatching,passenger transport,operation and maintenance.According to the system business requirements,38 GHz millimeter wave can also carry high-bandwidth services such as on-board PIS and on-board video.This scheme not only meets the real-time and reliability requirements of traction power supply and operation control system business,but also meets the voice communication requirements of dispatching and passenger transport required by the operation of long main lines while saving investment as much as possible and considering industrial support.
