Wireless communication systems in coal mines have these functions
Due to the complex geological conditions of coal mine storage, it is often threatened by natural disasters such as gas, fire, and dust. In addition, China's coal mine production is mainly underground operations, leading to frequent coal mine accidents. Therefore, the informatization transformation of mines is imperative. Constructing an integrated communication platform will provide reliable guarantees for production management, personnel management, and disaster relief.

What is the function of a coal mine broadcasting system?
In recent years, with the rapid development of computer network technology, the coal mining industry has gradually moved towards informatization. The coal mine broadcasting system is one of the "six major systems" for underground safety and disaster prevention established in response to the national safety supervision bureau and the national coal mine safety supervision bureau's requirements for the construction and improvement of underground safety regulations in coal mines.

How is precise personnel positioning in coal mines carried out?
Precise positioning of coal mine personnel: The wireless transceiver data board of the positioning substation sends a low-frequency encrypted data carrier signal outward via the transmitting antenna. When personnel carrying the KGE26 identification card enter the working area of the low-frequency transmitting antenna, the card is activated and simultaneously transmits encrypted information containing the target identification code via the high-frequency transmitting module in the card. The receiving antenna receives the carrier signal sent by the KGE26 identification card, and after being processed by the substation main board, the target identification code is sent to the working computer via DPSK or RS485 long-distance communication lines to achieve automatic tracking and positioning of mine personnel.

China is one of the world's largest coal consumers and producers. Therefore, with the increasing demands of modernized coal mines on production and safety, the limitations of traditional mine communication methods are becoming increasingly apparent. In recent years, with the tight supply of coal in China, the integration of coal mining enterprises has become increasingly high, and the production load of enterprises has become increasingly heavy.

What are the functions of underground communication systems?
China has many mines, most of which have special operating environments. Taking the coal industry as an example, most of its operations are underground, and communication between underground areas is very important. In particular, it is generally difficult for managers to understand the underground environment, making scientific scheduling and command impossible.
Therefore, the construction of an underground communication system is crucial.
With the development of modern information technology, underground communication systems are becoming increasingly widespread in mines. Underground communication systems mainly provide mutual communication among users within the system, enabling voice communication, data/video communication, and achieving personnel and environmental monitoring, providing scientific data for mine production management.
