煤矿井下通信的信源主要来自电话和各种监测监控系统,图像监控将成为主要信源.在一个大型矿井中,各种通信信息数字化后的总数码率目前不超过68Mbps.煤矿井下通信网是接入网,光纤是井下接入网中最好的传输媒质,宜采用光纤到大巷、光纤到工作面的光纤接入网方案.煤矿井下信息高速公路由光纤接入网、多功能终端和相关的软件组成.光纤通信的多点接入和低速数据的汇接适配是煤矿井下信息高速公路中的特殊技术.
The main source of coal mine communications from the telephone and monitoring and control systems, image monitoring will be the main source. In a large mine, the total digital rate digitized for various communications currently does not exceed 68Mbps. Coal mine communication network is the access network, optical fiber is the best transmission medium underground access network should adopt fiber to the road, fiber to the face of the optical access network program. Coal Mine Information Highway consists of optical access network, multi-functional terminal and related software. The multi-point access of fiber-optic communication and the convergence of low-speed data are special technologies in the information highway of coal mine.
