Coal industry automation based on private network wireless communication technology [Copy link]

Based on the private network wireless communication technology, the organic combination of coal mine automation and dedicated wireless network is realized. The system can achieve full compatibility with the existing equipment of coal mines, without rearrangement, which can save a lot of optical cable investment, and can flexibly realize underground voice communication function, signaling transmission and control functions. With the development of the automation level of the coal industry, underground wired communication is far from meeting the needs of a large number of mobile workers and their management in the mine, so the introduction of wireless communication technology is crucial for coal mines to improve efficiency and achieve safe production. The underground wireless communication system of coal mines can control the underground working equipment of coal mines with wireless modules, and can realize the real-time contact between production management personnel, front-line staff and dispatching personnel, as well as the real-time tracking, monitoring and positioning of coal mine personnel, so as to clearly grasp the position and activity trajectory of each person in the mine at any time. If a disaster occurs, the exact position of the personnel can be understood through the positioning system to achieve efficient rescue. Private network is a communication network built for special communication needs such as production organization, command and dispatch, and management within certain industry systems when public network communication in my country cannot meet the special applications of various industries. As private network users such as energy and transportation continue to improve their own management systems and pursue higher management efficiency, the needs of private network users are showing a more diversified and refined development trend, and they have put forward higher requirements for the application of communication technology. Private network communication technology is in the cross-evolution stage of traditional digital trunking system and broadband multimedia digital trunking system. With the development of economy and society, public safety incidents have received widespread attention worldwide, the application of private network communication equipment has become increasingly popular, and the global private network communication market will continue to develop steadily. In countries where public communication networks are relatively mature, their private network development has also achieved a certain scale and produced good economic benefits.

The coal industry has relatively high requirements, and wireless is also difficult to deal with.
