The performance of UWB positioning technology has been recognized by the regulatory authorities. Starting from the coal mine personnel positioning system, according to the underground environment of coal mine, a mature coal mine personnel positioning system has been developed and successfully applied for many years.

Mine personnel positioning system accurate management solution

In order to fully implement the spirit of the Fifth Plenary Session of the 19th CPC Central Committee and continue to modernize the system and capacity for mine safety management, the State Administration of Mine Safety Supervision and Administration organized the compilation of the 14th Five-Year Plan for Mine Safety Production (Draft). Carefully calculated, it can be called the application of precise positioning technology at present, only uwb manufacturers ultra broadband indoor positioning and ranging module technology can meet the requirements of the positioning accuracy of the coal mine personnel positioning system.

Equipment requirements for coal mine personnel positioning system solution

Coal mine personnel positioning system architecture: The coal mine positioning system based on the Internet of Things technology is mainly composed of positioning base station, positioning label, positioning engine software, coal mine personnel positioning system is composed of a number of positioning units, each unit is composed of four base stations, to achieve three-dimensional positioning. The base station obtains the location tag distance in the area in real time, sends it to the location server, and calculates the coordinates of each tag.

Positioning base station: The safety type positioning base station has a high explosion-proof rating, and the IP67 waterproof rating fully meets the relevant requirements of underground coal mine work. uwb manufacturer UWB indoor positioning and ranging module positioning base station ranging distance is not less than 400~600 meters, ranging accuracy is less than 0.5 meters. Therefore, it is recommended to install a positioning base station every 200 to 300 meters for high precision personnel positioning.

Positioning label: This positioning label is very consistent with the mining work related requirements, can also be used with the safety helmet. The safety belt is bound to the mine lamp and has the SOS one-button help function.

How to realize the coal mine personnel positioning system with uwb manufacturer's UWB indoor positioning and ranging module? The personnel positioning system of coal mine connects the underground and the ground through the communication network. The integration of cost safety UWB explosion-proof base station and other auxiliary equipment can solve the problem of mine voice communication, data transmission, personnel scheduling and other services replace the traditional communication system. Fully consider the production and management characteristics of modern mining enterprises, meet the balance between safe production and efficiency, improve the level of mine communication through advanced wireless communication technology, and give full play to its important role in production management.

Value of coal mine personnel positioning system solution

2.MAR certification, safe and reliable: meet GB3836 explosion-proof requirements, meet the requirements of AQ6201 standard

3. Cm-level UWB coal mine personnel positioning system: strong anti-interference ability in industrial scenes, more than 99% of the industrial production environment can be used

4. Exclusive multi-card monitoring: domestic exclusive on-site multi-card monitoring, card replacement detection and alarm device

5. Construction of digital mine, comprehensive process control, improve accident prevention ability

uwb manufacturer UWB indoor positioning module opens the 3D positioning mode of underground personnel positioning system UWB. In order to strengthen coal mine energy safety production and reduce coal mine accidents, the State Coal Administration has put forward higher requirements for six system technologies in coal mine, among which the positioning accuracy of underground personnel in coal mine must meet 10cm. As a high-precision personnel positioning technology, UWB underground personnel positioning system conforms to response policies and technical standards, and effectively meets the needs of enterprise users. It has become an inevitable trend for coal mine enterprises to strengthen intelligent construction through high and new technology.

Three dimensional safety production management model of underground personnel positioning system in coal mine

In the field where satellite positioning is not applicable, there are many indoor positioning technologies, among which the most commonly used indoor positioning technologies for personnel in underground coal mine are: RFID, Zigbee, UWB positioning. The scheme of personnel positioning system in coal mine generally adopts the UWB positioning technology with the highest accuracy and strong anti-interference.

1. In order to realize personnel accurate positioning, uwb manufacturer's UWB indoor positioning and ranging module adopts personnel accurate positioning UWB positioning technology. The explosion-proof UWB positioning base station of roadway in underground coal mine can realize accurate linear positioning of roadway and three-dimensional positioning of large area requiring accurate positioning, with positioning accuracy of 5-10 cm.

2. 3D model construction of 3D visual production safety management platform for coal mine positioning, synchronous upload of coal mine operation instruction manual to 3D engine model conversion, import of 3D engine for safe production, which can realize coal mine construction verification, more intelligent regulation of underground personnel operating standards, reduce accidents.

3. According to the needs of underground operations, improve the platform information management function, integrate multi-source data, and further realize electronic fence, alarm management, environmental monitoring, video linkage and video analysis functions
