基于Wi-Fi与xDSL的矿井应急救援多媒体综合通信系统设计及应用

Design and Application of Integrated Multimedia Communication System for Mine Rescue Based on Wi-Fi and xDSL

针对井下有线通信系统铺设困难和无线通信系统易受井下空间约束、带宽衰减快、传输距离短的缺点,设计了一套基于有线xDSL和无线Wi-Fi协议的多媒体综合通信系统。经过验证,该系统传输速率高,通信距离长,适合井下多种数据实时融合通信的需要,是煤矿应急救援的综合通信中重要的信息平台之一。

According to such shortcomings as difficulties of lying wire communication system underground and the un- derground space restriction, quick bandwidth attenuation and short transmission distance of the wireless communica- tions system, an integrated multimedia communication system was designed based on the cable, xDSL, and wire- less, Wi-Fi protocols. The verification shows that such a system is of high transmission rate and long communication distance, satisfying the need of various real-time data integrated communications underground and it becomes one of the important information platforms in the integrated communications for coalmine emergency rescue activities
