电力线载波数据通信在煤矿企业中的应用

Application of Power Line Carrier Data Communication in Coal Mine Enterprise

文章旨在介绍一种基于煤矿企业三相四线制、50Hz供电网,利用电力线载波数据通信方法,组成一个在煤矿企业内部电力网线上实现煤矿企业内部局域网数据可靠传输的方案。利用该方案,煤矿企业可方便地独立组成一个内部数据传输系统,进行内部日常供销数据的可靠传输并进行煤矿企业内部各部门的可靠通信,从而代替煤矿企业现在使用的计算机传输系统和通信系统,为煤矿企业提高经济效益服务。

This paper aims to introduce a coal mine enterprise three-phase four-wire system, 50Hz power grids. By using the method of power line carrier data communication, a power grid in the coal mine enterprise online intranet which can achieve reliable data transmission program will be formed. By using the program, the coal mine enterprises can be easily and indeperndenting composed of an internal data transmission system, to conduct an internal day- to-day supply and marketing by reliable data transmission and the coal mine enterprise within all departments and counters reliable communication. Thus, the communication system of using computers amd transmission systems are replaced, in order to improve the economic benefits of the coal mine enterprise.
