Abstract:At present,most of the pumping stations in Guizhou still use traditional manual operation and drainage methods,and there is a great potential safety hazard. In view of the disadvantages of the existing drainage system,the existing drainage system is reformed by using PLC control cabinet,protection sensor,liquid level detection device and audio-video camera,so that the remote set control system of the well sewer house can be rooted in the real-time water level and the running time of the pump. The remote centralized control system of underground pump house can automatically start and stop the pump according to the real-time water level and the running time of the pump,the principle of “avoiding peak and valley” and the principle of “working in shifts”,thus realizing the automatic control of underground pump house drainage and the remote centralized control of the ground.
Keywords:coal mine pumping station;programmable logic controller(PLC);audio and video

目前貴州大多礦井水泵房仍然采用傳統的人工操作排水方式,這種排水系統由于自動化程度低,應急能力差,無法做到根據水位或其他參數自動開停水泵,存在很大的安全隱患。2017年貴州出臺了《省人民政府關于煤炭工業淘汰落后產能加快轉型升級的意見》(黔府發[2017]9號),目標之一就是智能機械化水平要顯著提升[1]。黔金煤礦從煤礦排水生產實際出發,針對現有排水系統的弊端,結合現代工業技術和控制理論,利用PLC控制柜、保護傳感器、液位檢測裝置和音視頻對講云臺攝像儀對原有的排水系統進行改造,使井下水泵房遠程集控系統能夠根據實時水位及水泵運行時間,結合用電“避峰就谷”原則,按照“輪班工作制”自動啟動與停止水泵,系統實現了井下泵房排水的自動化控制和地面遠程集控。地面集控室操作人員能夠通過上位機監視水泵房相關設備的實時工況,能夠在操作界面調用音視頻云臺攝像儀器,進行變焦、變倍操作,多角度視頻監控;……
