Underground broadcasting communication system in coal mine

  • Underground broadcast communication system in coal mine is the key component of coal mine safety production, it mainly realizes the functions of safety broadcasting, dispatching and commanding, safety monitoring, public voice and so on. The system is usually composed of the network paging microphone in the well part and the network audio transmission module in the underground part, which can communicate through the industrial Ethernet to achieve the full coverage of the underground broadcast and communication. With the increasingly complex mine operating environment and the improvement of the Internet of Things technology, the demand for visualization is more and more, intuitive visual interface, users can carry out video calls, conference management and other operations through the graphical operation interface, to further improve the production efficiency and safety management level of mine.

Characteristics of underground broadcast communication system in coal mine

1. The coal mine broadcast communication system was originally mainly used for basic communication functions such as voice calls, but after the addition of the video system, it can support video calls, video conferences and other video interaction forms, greatly enriching the media types and interaction methods of communication, so that users can realize face-to-face communication, and enhance the intuitedness and effect of communication.

2, the video system adopts the standard SIP protocol, can support a variety of terminal equipment access, including mobile phones, tablets, smart Android screen, etc., can support Ethernet, 4G/5G, WiFi and other communication methods, users can carry out video communication anytime and anywhere on different devices, free from the restrictions of equipment and location, improve the flexibility and convenience of communication. The SIP protocol also enables the underground terminal equipment to easily access the mine's existing SIP system.

3, a variety of sizes of downhole terminal products, have passed the coal safety certification, support Android or windows operating system, can be applied to a variety of downhole scenarios, including fixed scene applications or vehicle applications.
