摘　　要：井下电力监控系统实时监控煤矿供电设备的运行状态,其中电力监控的通信系统确保传递信息的实时性及准确性,是其最重要组成部分之一。设计了以地面主控计算机为通信的控制中心,井下监控单元为现场采集控制器,并分别基于以太网和RS485通讯,实现了远程数据光纤通信及设备层信息传输。试验与现场研究结果表明该通信方案能够稳定、高效、准确地实现信息传输,保证了系统的可靠运行。The coal mine power monitoring system can monitor the operatinal status of coal mine power system, the system of communication is the mot important part of power monitoring system , which can en- sure the information tansmitted correctly and timely. It is designed that main controlling computer is used as communicated and controlled core, the underground monitoring stations is used as on -the -spot col- lecting controller,, and the communication is based on Ethernet and RS485, this method of design realize remote data trasmission by fiber and information tansmission for equipmens. The experimental results demonstrate that the design, which could ensure realiable operation of the monitoring system , could tans- mit information stably, efficiently and correctly.
