摘　　要：专用无线通信系统在轨道交通行业中起着重要作用。新建线路的无线通信系统接入既有线网存在风险,实现两条线路无线通信系统的互联互通是接入的难点之一。西安地铁14号线需与机场线连接,且其无线通信系统需接入线网。本文研究了互联互通中传输系统、无线通信系统、无线调度通信、集群交换控制中心等的接入,总结无线通信系统升级中硬件及软件的关键点。Dedicated wireless communication system plays an important role in rail transit.There is certain risk when the wireless communication system of a newly-built railway line is connected to that of the existing railway network and it is hard to realize the interconnection and interoperability of the wireless communication systems.In the case of connecting Xi’an Metro Line 14 with the airport line,it is required that the wireless communication system of Line 14 be connected with that of existing rail transit network.Therefore,the interconnection and interoperability of the wireless communication systems is studied,including the connection of the transmission systems,wireless communication systems,radio dispatching communications,and virtual trunking control centers(MSOs)and the key points of upgrading the hardware and software of wireless communication systems are summarized.
