Low-power UWB module personnel positioning helps the safe operation of coal mine bridges. What is personnel positioning? The emergence of UWB high-precision personnel positioning technology has realized ultra-wideband and high-speed data transmission within a short distance. The characteristics of its modulation mode and multiple access technology make it have the characteristics of wide bandwidth, high-speed data transmission, low power consumption and high security performance that other wireless communication technologies cannot have. Today, low-power UWB module personnel positioning systems are often used in major companies. So, how can coal mining enterprises achieve the effect of personnel positioning? What is the significance of bridge personnel positioning? Let's take a closer look.

Safety production is the top priority of coal mining enterprises. Coal mine underground positioning system is playing an important role in curbing overcapacity production, post-disaster rescue, preventing personnel from entering dangerous areas, and preventing mechanical collisions, and to a large extent ensures safe production in mines.


The low-power UWB module precise personnel positioning system consists of uphole equipment and downhole equipment. The uphole equipment includes base station controller, positioning server, and underground equipment includes positioning base station, mobile terminal and RFID electronic tag. The uphole equipment and the downhole equipment are connected by optical fibers, wherein the positioning base station includes MIMO.


RFID radio frequency identification module, CCD image acquisition module, micro-processing unit, power supply module, wireless communication module, Ethernet interface, optical interface; mobile terminals and monitoring terminals can obtain and display the location information of moving targets from the positioning server. The patented technology of the utility model has the advantages of simple structure, convenient deployment and maintenance, low system energy consumption and high positioning accuracy, and is suitable for real-time tracking and positioning of moving targets in various complex environments and limited spaces.


The low-power UWB module personnel positioning system can monitor on-site operations in a timely manner through personnel area positioning system, video surveillance, video linkage with key areas, and realize personnel cross-border alarm, outsourced low-security level alarm, no signal or overtime alarm. High-risk operations can effectively realize real-time safety monitoring and risk control of personnel.

1. Realize on-site operation monitoring of outsourced personnel, real-time monitoring of illegal intrusion, overtime operation, video linkage monitoring of anti-violation operations, personnel safety training level and certificate qualification examination, which effectively reduces the safety risk of outsourced personnel.

2. Realize real-time management in place, implement the responsibility system for production safety of personnel at all levels, and urge production management personnel to "sink the center of gravity and move forward" to strengthen safety management and supervision, and realize "controllable, controllable, and controlled" production safety.

3. Realize the inspection management of on-site inspectors, provide personnel positioning, historical track query, provide effective management methods for post-accident analysis and daily management, and improve inspection quality.

4. Realize the on-site operation management of tools that are over-checked and unchecked, and prevent tools from causing potential safety hazards in on-site operations.

5. Realize the safety monitoring of vehicles and outsiders, prevent unauthorized entry by mistake, and monitor the travel trajectory of personnel in real time.


The significance of low-power UWB module bridge personnel positioning and the importance of bridge manufacturing in the power industry are irreplaceable. The product can transmit wires well, and can also ensure the normal flow of current. The bridge built by metal tube welding has an ideal stabilization effect; the bridge design is simple, the workers can easily reach the top of the bridge, and it is convenient for the maintenance and inspection of the circuit. The bridge frame makes the installation of the cable more convenient, as long as it is placed in the designated position of the bridge, the cable can be fixed. The top and bottom of the bridge are metal machined to take the weight of the cable and hold the cable well to make sure the cable doesn't break easily. The bridge saves the consumption of metal materials and ensures the normal use of cable materials. In a variety of complex environments, bridges will not collapse.


When the operator is working in the bridge area, the UWB module can accurately locate the position information of the relevant personnel, and the movement trajectory can prevent accidents.
