1. Using wireless two-way communication ranging and positioning technology (UWB positioning) 2. UWB technology is used for wireless transmission of personnel identification card 3. The radius of the effective coverage area of the positioning base station signal shall not be less than 400m in the open and unobstructed environment 4. Set the mine personnel positioning, attendance, management, alarm call, data acquisition and other functions in one 5. Using TCP / IP Ethernet (RS485 bus optional) + optical fiber transmission, long communication distance, stable and reliable performance 6. The system architecture can be extended through Ethernet 7. The portable identification card is small, light and easy to carry. It can be placed on the helmet, belt and miner's lamp rope or integrated into the miner's lamp.
System composition
The system is mainly composed of monitoring host and software of ground central station, communication cable or optical cable, mine explosion-proof and intrinsically safe power box, mine intrinsically safe network switch, positioning base station and lightning arrester. The monitoring and management software processes, displays and prints the data. The mining intrinsically safe network switch constructs the communication transmission network through the network electrical port or optical port, and connects the positioning base station, monitoring host and other equipment; the power box provides the intrinsically safe power supply for the mining intrinsically safe switch and the positioning base station; the positioning base station collects and calculates the data through the mining intrinsically safe exchange The machine is uploaded to the ground center station; the identification card is worn on the staff for staff identification and positioning.
