Design and application of visual remote control of water retaining device in coal mine
In order to realize the remote control of the water retaining device in coal mine and make the water retaining device run reliably,the remote control function of the existing water retaining device in coal mine was studied to realize the purpose of automatic downsizing of underground workers.The results show that the liquid level sensor,stroke switch and other analog quantities are input into the PLC,and the water level monitoring before and after the water baffle device and the switch of the water baffle device are realized through the data operation and processing inside the PLC,and the communication and video monitoring module can grasp the downhole situation in the dispatching and monitoring center in real time.When the coal mine burst water,it can avoid casualties and reduce property losses.
