本文介绍了一种煤矿井下电力监控系统，该系统由井下隔爆配电开关和井上计算机监控系统构成。井下隔爆配电开关以K7M-DR14UE 可编程控制器为控制核心，井上计算机监控系统由VC++开发而成，可实时监测井下电网参数，并及时显示和报警过欠压、断相、漏电、过载、短路等故障。关键词 K7M-DR14UE 隔爆配电开关 监控系统 Cserial 类Study And Application Of Power Monitored Control System For Underground MineZhangYong1 HeAiXiang1 YueYaobin2 (1 ShanDong Institute of Business and Technology, Shandong, Yantai, 264005; 2 QingDao University of Science and Technology, Shandong, Qingdao, 266510 ) Abstract: This paper introduces a kind of Power Monitored Control System For Underground Mine, which comprises of underground mine flameproof feed switch and computer monitored control system on the ground. K7M-DR14UE programmable logic controller is used as core of the flameproof feed switch. Computer monitored control system is developed from VC++, which can monitor the underground electric network parameter in real time, find and alarm over voltage、 under voltage、open phase、electric leakage、over load、short circuit etc in time.Key word: K7M-DR14UE、Mine Flameproof Feed Switch Controller、Monitored ControlSystem、Cserial Class
