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。
The article aims to introduce a scheme based on the coal mine enterprise three-phase four-wire system, 50Hz power supply network and the use of power line carrier data communication to form a reliable transmission scheme of local area network data within the coal mine enterprise internal power network. By using this solution, coal mine enterprises can easily form an internal data transmission system independently and reliably transmit internal daily supply and sales data and carry out reliable communication among various departments within the coal mining enterprise, so as to replace the computer transmission systems and communication systems currently used by coal mining enterprises, For coal mining enterprises to improve economic efficiency services.
