煤矿井下无源光网络的研究与应用

Research and Application of the Passive Optical Network of the Underground Coal Mine

无源光网络(PON)在电信网中已得到广泛应用,但用于煤矿井下综合自动化网络平台则是刚刚起步。本文介绍了无源光网络的发展过程、EPON的工作原理、以及利用EPON技术构建的煤矿井下综合自动化传输平台的系统原理、系统结构、系统特点和主要技术指标。煤矿GEPON系统的建设为矿井各种子系统的建设接入提供了一个高速、安全、稳定的平台。该平台是矿井信息传输技术的一个突破,代表着国内领先水平。随着GEPON系统在煤炭系统的推广应用,其必将为我国煤矿安全生产提供更加可靠的保障。

Passive Optical Networks （PON）has been applied widely in telecommunication network,but it is just starting at the comprehensive automatic network platform of underground colliery. The developing progress of PON, working principle of EPON （Ethernet PON）,and the principle,structure,characteristics and basic mechanical design feature of comprehensive automatic network platform for underground colliery are introduced in this article. The construction of GEPON system of underground colliery provides a high-speed, safety and stabilized platform that is a breakthrough in the information transmission of colliery, and represents national advanced level. It will provide more reliable safety in state coal mine production accompanied by GEPON system applied and popularized in the coal field.
