城市轨道交通通信资源共享研究

Research of Communication Resource Sharing in Urban Rail Transit

随着我国城市轨道建设规模和范围的不断扩大,通信系统的资源共享问题日益突出,城市轨道交通通信系统的资源共享不仅涉及工程建设投资,还影响维护定员和运营成本。为此,从2大方面入手分析研究了城市轨道交通的通信资源共享方案,并针对目前城市轨道交通通信系统的现状,提出通信资源共享的建议及方法,总结得出资源共享有利于城市轨道线网间的互联互通、提高通信网络可靠性的结论。

With the up-scaling and expansion of urban mass transit construction in China,the problem of sharing communication resource become more and more obvious,which affects not only the investment on the construction,but also the number of the maintenance staff and the operation cost.This article analyzes the resource sharing solution of the communication system of urban mass transit in two major aspects and gives some advice and method base on the present situation of the communication system of urban mass transit.It is concluded that resource sharing can facilitate the interconnection of different networks of the urban mass transit and improve the reliability of the communication network.
