Detailed introduction

System Overview:
The mine personnel positioning system uses the world's advanced wireless network transmission technology to truly realize the precise positioning of underground personnel. It can provide rich data and graphic information, monitor the current position and walking path of underground personnel and equipment in real time from the ground, count the number and distribution of underground personnel, and provide attendance function according to the actual situation of coal mine. Thus, before the accident, the safety production monitoring center can master various safety production elements in different positions of underground at any time. So as to take positive and effective preventive measures; after the accident, can quickly retrieve the accident occurred at the time, even after the accident occurred for a considerable period of time, the specific distribution of underground staff location, so as to develop timely and effective rescue measures, and the implementation of effective on-site rescue command.
