无漏泄电缆无线列调弱场区通信系统设计

Design of Communication System without Leakage Cable in Weak Field Area of Wireless Train Dispatch

漏泄电缆加中继器技术解决隧道内的异频双工、半双工弱场通信问题已很成熟,但这种技术不适用于C制式系统。无漏泄电缆弱场区中继通信系统为解决C制式下的无线列调弱场区通信问题提供了一套完整的方案,包括明区间弱场中继通信和隧道内弱场中继通信。对系统设计和工作原理、站址的选定、同频干扰的避免以及隧道内平板天线的设计等都作了详细介绍。

It has been mature for leakage cable plus repeater technique to solve the weak field communication problems of different- frequency duplex and half-duplex communication in tunnels, but this technique does not apply to C mode systems. Weak field relay communication system without leakage cable provides a complete scheme to solve the problem of weak field communication in C-standard wireless dispatching system,which includes relay communication in open area weak field and relay communication in tunnel weak field. The system design and operation principle, site selection, co-channel interference avoidance and the flat panel antenna design in tunnel are described in more details.
