GSM-R系统在武广高铁的应用

First, apply to the Wuhan-Guangzhou high-speed railway GSM-R communication system is characterized by GSM-R (Globle System of Mobile foRRailway) specifically for the needs of railway mobile communications and the launch of a dedicated communication system by the International Union of Railways (UIC) and the European Telecommunications Standards Organization development of technical standards, adopted by many European countries. It has been exceeded based on the GSM and its function is to realize a sophisticated technical system mobile voice and data transmission via wireless communication.
（三）CTCS-3级高速运行情况下的移动通信 使CRH3（中国铁路高 速）型动车组在武广高速铁路上以350km/h的速度安全运行。基于承载 CTCS-3业务的GSM-R系统确保行车安全。今天武广高铁采用GSM-R通信 网络创造了CRH3型动车运行时速394公里的世界记录。
(C) mobile communications CTCS-3 class high-speed operation under so CRH3 (China Railway High-speed) type EMU safe operation to 350km / h speed on the Wuhan-Guangzhou high-speed railway. Carrying CTCS-3 business system based on GSM-R to ensure road safety. Today, the Wuhan-Guangzhou high-speed railway network using GSM-R communication created CRH3 type EMU run world record speed of 394 kilometers.
（一括：组呼、群呼、增强多优先级与强拆）。功能寻址 （调度）。基于位置的寻址（机车呼叫前方车站、后方车站）。高速列 车运行情况下的移动通信。大量特殊的数据业务需求（列控、车次号 等）。
(A) railway GSM-R GSM public network has a relatively specific needs of different user levels (voice calls, including: group calling, enhanced multi-priority and demolitions). Addressing the function (scheduling). Addressing (call ahead locomotive station, behind the station) locationbased. Mobile communications in case of high-speed trains running. Business needs a lot of special data (train control, train number, etc.).
（二）武广高速铁路GSM-R无线网络采用单层交织冗余覆盖 在列控 系统中,无线闭塞中心(RBC)与车载设备无线连接中断,主要是由于GSM-R的 无线网络连接失效,即车载ATP（列控车载系统）与BTS(基站)的连接中断, 可能是ATP或BTS发生了故障,其中BTS故障的影响可能性大,因为它的故障 会造成整个BTS无线网络覆盖区域内的无线连接中断,导致ATP无线连接超 时由CTCS-3级转入CTCS-2级控车，影响该区段内的所有列车运行。
GSM-R系统在武广高铁的应用
GSM-R system in the WuhanGuangzhou high-speed rail
GSM-R系统在武广高铁的应用,为我国高速铁路实现铁路信息化 建设跨越式发展做出了一个成功的典范。采用所谓“天网”的 GSM-R通信网络，实行高速动车组准确定位和控制。武广高速铁 路通信网络的应用突出了安全、完整、统一、灵活、可靠、可扩展 性的特点。GSM-R系统为铁路沿线人员(包括铁路工作人员、旅客、 其他用户)提供了语音和数据通信技术服务,为基于GSM-R的CTCS3(列车运行控制系统)级列控提供了通信平台 GSM-R system in the Wuhan-Guangzhou high-speed rail applications for the realization of China's high-speed railway construction railway information by leaps and bounds made ​a successful model. The so-called "Skynet" of GSM-R communication network, the implementation of high-speed EMU accurate positioning and control. Application of the Wuhan-Guangzhou high-speed railway communication network highlights the security, integrity, unity, flexible, reliable, scalable features. GSM-R system along the railway personnel (including railway staff, visitors, other users) provides voice and data communications technology services for GSM-R based on the CTCS-3 (Train Control System) level provides a communication platform for train control .
(B) The Wuhan-Guangzhou high-speed railway GSM-R wireless network using single interwoven redundant coverage in train control systems, RBC (RBC) and vehicle equipment wireless connection is lost, mainly due to the GSM-R wireless network connection failure, that car ATP (car train control system) and (base) BTS interrupted connection may be faulty ATP or BTS, BTS failures which affect the possibility of large, because its failure would cause the entire BTS coverage area of a wireless network wireless connection is interrupted, resulting in ATP wireless connection timeout by the CTCS-3 级 into class CTCS-2 control cars, affecting all trains within the section.
武广高铁对无线连接失效采取的技术方案是采用单层交织冗余覆盖，铁路沿 线由一层无线网络进行覆盖，但在系统设计时加密基站，使得两相邻基站的 场强相互覆盖到对方站址，这样可保证在非连续基站故障的情况下，GSM-R 网络仍能够正常工作。而且采用不同路由的奇偶数基站保护“环型”结构， 在这种无线网络结构下，基站单点故障时不会出现无线网络覆盖盲区，只有 连续基站故障或BSC（基站控制器）故障时才会影响无线覆盖，因而系统可 靠性很高；同时由于基站加密，覆盖电平较高，抗干扰能力也较强。保证了 动车350km/h运行速度车-地之间双向数据传输安全。 Wuhan-Guangzhou high-speed rail failure to adopt wireless connection technology program is the use of single interwoven redundancy covered by a layer of railway wireless network coverage, but in the system design encryption base, making the field strength between two adjacent base stations to cover each other mutual station site, it will ensure that in the case of non-continuous base station failure, GSM-R network is still able to work properly. And the number of base stations using parity protection different route "ring" structure, in which the wireless network infrastructure, wireless network coverage blind spots will not appear when the base single point of failure, malfunction or BSC only when continuous base (base station controller) failure will affect the wireless coverage, and thus a high system reliability; same time as the base encryption, coverage level is higher, stronger anti-interference ability. To ensure that the EMU 350km / h operating speed car - two-way data transmission security between ground...
