摘要
从列车运行控制系统、无线调度语音通信、车载视频监视、列车文本下发、列车运行状态信息监测业务等角度出发,分析市域铁路专用移动通信系统业务应用需求。从抗干扰能力、接入机制、移动能力、多普勒效应、综合承载适应性、互联互通等多方面比对铁路、地铁当前在用的移动通信技术制式,结合市域铁路特点并分析国内外技术应用现状,探讨适用于我国市域铁路的移动通信技术制式。提出市域铁路移动通信技术制式选择不应局限于GSM-R系统,采用宽带移动通信系统是发展的必然趋势,可在一些城市开展LTE甚至5G移动通信系统的试验和试用性建设。
From the perspectives of train operation control system, wireless dispatching speech communication, onboard video monitoring, train text issuing and train operation status information monitoring, the paper analyzes the business application requirements of the mobile communication system dedicated to suburban railway. The paper compares current mobile communication technology standards between railway and metro from the aspect of anti-interference ability, access mechanism, mobile ability, Doppler effect, comprehensive bearing adaption ability and connectivity. The paper discusses the mobile communication technology standards that are suitable for suburban railway according to its characteristics. The paper also puts forward the standards should not be confined to GSM-R system, and it is an inexorable trend to adopt broadband mobile communication system, which means that the test and probationary construction of LTE or even 5 G mobile communication system can be conducted in some cities.
