煤矿井下电力线通讯系统的设计与实现

Underground Power Line Communications System Design and Implementation

针对目前煤矿使用的信息传输系统,提出以煤矿井下铺设好的低压电力线作为通讯介质而建立的信息传输系统,通过对通讯技术、电力线特性及煤矿井下特殊环境的分析和研究,采用了基于Lonworks总线技术的电力线载波通信方式,完成了煤矿井下电力线通讯系统的设计和研发,经实际测试实现了载波通讯,为产品的开发奠定了基础。

In view of the present coal mine information transmission system for use in coal mine,the article puts forward the paved low-voltage power line as a communication medium and the establishment of the information transmission system.Based on the analysis and research of communication technology,power line characteristics and the coal mine mine shaft special environmental,by means of Lonworks bus technology of power line carrier communication mode,the article completed the underground power line communication system design and development,through the actual testing to achieve the carrier communication,for product development has laid a Foundation.
