Underground Personnel Tracking System

Because of the large liquidity of coal mine underground work personnel, vehicles and other mobile target. Once flooding accident, fire disaster and other accidents occur, this will bring great difficulties to the relief work. Therefore, mine personnel management system can be used for well personnel tracking and locating, enhancing mine disaster relief work, improving production dispatching. It can also perform security monitoring and inspection, check staff attendance, handle urgent incidents and keep track of the position and traces of various underground all kinds of personnel and other moving targets. 

Product Details

Because of the large liquidity of coal mine underground work personnel, vehicles and other mobile target. Once flooding accident, fire disaster and other accidents occur, this will bring great difficulties to the relief work. Therefore, mine personnel management system can be used for well personnel tracking and locating, enhancing mine disaster relief work, improving production dispatching. It can also perform security monitoring and inspection, check staff attendance, handle urgent incidents and keep track of the position and traces of various underground all kinds of personnel and other moving targets. 

Also we can get accurate statistics of each shift of people in the well, various types of operation. All of these will provide accurate data for safe production, reasonable employment, well attendance. Coal mine personnel management system for underground personnel wireless positioning, tracking and attendance. In line with the resource sharing, the system makes full use of resources on the basis of the existing system. On the basis of modern wired and wireless communication technology, control computer system, Central control computer system is set on ground operation department, while transmission substation and wireless transceiver are arranged at related position. 

The transmission substations and center control computer systems are connected via optical fiber or cable network, underground personnel, vehicles, equipment and other targets respectively have a sign of wireless identification card. The system will have real-time understanding of underground personnel and distribution through the communication between transmission substation and wireless transceiver. The current or historical period of the area and activities of designated personnel can be arbitrary queried. The attendance information such as the number of going to mine, the time of going to mine and so on can be properly statistical, and related reports can be printed. It has alarm function of real-time fault alarm and timeout, overcrowding, entering the danger zone, etc. 

Through a variety of sound and light and other methods, the system can actively inform people to evacuate from dangerous zone before the incidents occur. When underground personnel are in danger, they can issue a distress signal to the ground. After the accident, it can timely lock the specific location of trapped and killed personnel, providing accurate information for search and rescue work. This will offer effective means for production command scheduling, safety monitoring and inspection, personnel attendance, emergency handling, etc. The system can transfer relevant data to management departments at all levels at the same time, providing an important basis for supervision and decision-making for leaders at all levels.


• Adopting wireless two-way communication: Underground personnel can look for emergency help, while people on the ground can notify underground personnel to evacuate through a variety of sound and light alarm method

• Personnel identification card achieves wireless transmission by using 2.4G technology

• Effective coverage area radius of wireless transceiver >20m

• Including such function as underground personnel positioning, attendance, alarm call, data collection, etc.

• Using RS485 bus + optical fiber transmission, with long communication distance, stable and reliable performance

• The two 2 core communication cable between transmission substation can be connected in series, relay cascade

Portable identity card with small volume, convenient to carry, can be placed in the safety helmet, belts, miner's lamp cord or integrated within the miner's lamp


The system mainly consists of ground central station monitoring host computer, software, communication cable or optical cable, mine flameproof and intrinsically safe power supply box, underground transmission substations, underground wireless transceiver, identification card, and lightning protection grid, etc.. Monitoring software can process, display and print data, the underground transmission substation is connected to monitoring host through the RS485 interface or optical fiber. The power supply box provides the intrinsically safe power supply for underground transmission substation and wireless transceiver. Underground transmission substation links up with wireless transceiver by wired two-way communication. After processing the collected data, then transmit the data to the ground center

station through the transmission line. The identification card worn by staff is used to identify the staff.
