In the mine, tunnel, underground pipe gallery and other work scenes, usually have the characteristics of harsh environment, high risk factor, and there are also multi-type, multi-process inspection and maintenance, in order to ensure the operation order and personnel safety, indoor positioning technology has become an urgent need to introduce technology, mainly from the following two aspects play an important role.

Personnel daily management, real-time location of personnel, and based on location data to achieve personnel attendance, tracking and positioning, optimization, intelligent inspection.

Safety early warning and post-disaster first aid, set up personnel rights and electronic fences in specific areas to prevent cross-border operations; Real-time positioning of vehicles to prevent overspeed and human-vehicle collision; When dangerous situations occur, the system can issue evacuation orders to the operators according to the region, and the operators can also automatically alarm through the SOS button of the positioning label to ensure real-time safety rescue. Can carry out a variety of human behavior monitoring, effectively prevent safety accidents; Statistics of the distribution of personnel in a specific area at any time, in case of danger, to provide data support for timely rescue.

In the mine, tunnel, underground pipe corridor and other scenarios, mainly based on human positioning, the accuracy requirements are basically 1 to 3 meters, and the terminal requires versatility, low power consumption, and easy to carry.
