煤矿井下4G通信系统的设计与应用

Research on Design and Application of 4G Communication System in Coal Mine

为满足煤矿井下复杂条件下的无线通信需求,设计了一套煤矿井下4G通信系统,首先介绍了平煤八矿工业环网结构和通信系统现状,然后详细介绍了系统的设计方案。经实际应用表明:该系统实现了基于4G的移动通信、调度、控制及信息采集功能,对保障矿井安全生产及智能化建设具有重要意义。

In order to ensure the wireless communication requirements under complex conditions in coal mines,a set of underground 4G communication systems in coal mines were designed.First,the industrial ring network structure and current status of communication systems in Pingdingshan Tian'an Coal Mining Co.,Ltd.No.8 Mine were intro⁃duced,and then the system design scheme was introduced in detail.The practical application shows that the system realizes the functions of mobile communication,scheduling,control and information collection based on 4G,which is of great significance to the safety production and intelligent construction of coal mine.
