Development Of High-Speed Rail EUHT Internet Management System

With the development of economy and the increasingly rapid pace of life,high-speed rail(HSR)has become an indispensable means of transport in modern life.But after speed increase with HSR,there has been a serious communication problem.When HSR running at high speed,the wireless communications inside and outside the HSR will be seriously affected,wireless signal in the HSR has all but disappeared.Even the fourth generation mobile communication technology(4G)can not send a steady signal.So that the interior information about HSR runing,such as the video can not be transmitted by wireless communication to the outside HSR management station.It has brought great inconvenience to rail operation and management.Therefore,rail communication problems within and outside HSR,has become an urgent problem.There are some C/S or B/S softwares based on IP management and communications can be used.But each company has its own requirements,common software is unable to meet the requirements of the changing needs of the company.And HSR EUHT network management systems functional requirements is continually changing currently.So to buy domestic software requirements will make the system able to meet the ever-changing needs,and the scalability of the system is not good.It is essential to independent development of HSR EUHT network management system.Enhanced Ultra High Throughput(EUHT)device is a good solution to this problem.Network data transmission speed of EUHT communication technology is more than that of the current fourth-generation mobile communication technology.EUHT is the first communication technology system in the world that can solve"integration of mobile broadband",which is developed by the Guangdong New Bank Line limited cooperation.And it consists the core chip and whole package of technical standards,with completely independent intellectual property rights.EUHT has the following advantages characteristic,that is,high speed,high bandwidth,high stability,low latency,low cost,and low power consumption,which is evidenced by the testing authority.EUHT easily solve many communication problems require high throughput.HSR EUHT network management system was developed based on EUHT communications equipment.HSR EUHT network management system is a B/S model network management system based on JAVA,and SpringMVC,Spring4,Mybatis technical framework was used to develop it.Currently,the functions of EAU,EBU,EDU,equipment condition monitoring,configuration management,fault management,topology management,and system management were completed,and preliminarily realizes high-speed communication problems within and outside.HSR EUHT is an internet management systems,which is based on EUHT antenna unit(EAT),EUHT Access Unit(EAU)EUHT base station Unit(EBU),and EUHT doom Unit(EDU).The systems are composed by the Universal Server,switch,and PC Terminal,which can manage and maintain the full range of ground communications network,wireless network,mobile network,and can monitor all EAU,EBU,EDU devices condition,and manage the devices fault,topology,configuration,performance,security,and comprehensively display EUHT system applications in the HSR.The internet management system's primary function is the EUHT device management,communication with the underlying EUHT device.Important functional modules are topology management,operational maps and GIS maps.At present,the V1.0 version of the system is a test running in a HSR,and overall results are good.
