Solution to Mine Personnel Location System
Solution to Mine Personnel Location System utilizing the latest wireless network transmission technology in the world, we can truly achieve the precise positioning of underground personnel. It can provide a ton of data and graphic information, monitor the current position and walking path of underground personnel and equipment from the ground in real time, count the number and distribution of underground personnel, and provide checking-in according to the actual situation of the coal mine. As a result, the safe production monitoring center can keep abreast of the locations of various elements for safe production before an accident happens, so that it can take effective preventive measures. After the accident, it can quickly retrieve the specific location of the underground personnel at the time of the accident, or even for a considerable period after the accident, so as to formulate timely and effective rescue measures and implement effective on-site rescue.
