Problems solved by technology
[0003] At present, the main forms of mobile communication in mines include power carrier communication, leaky wireless communication, intermediate frequency wireless communication, induction communication, PHS communication, and communication based on WiFi technology. These types of underground mobile communication systems have many problems. The performance is poor, the background noise is large, the full seam coverage of the underground roadway cannot be realized, and the adaptability of the system to the use environment is poor. In addition, because the mainstream mobile communication technology widely used on the ground is not adopted, the system upgrade cannot be guaranteed

The invention relates to a real-time control system for underground mobile communication and monitoring of a coal mine, which comprises an underground information acquisition system and a ground monitoring system, wherein the underground system comprises a cellular ultra-small mobile base station and an information acquisition terminal; the ground monitoring system comprises an SIP RAN platform and an overground monitoring console, a bearer network between the underground information acquisition and the ground monitoring system is an IP broadband network, the IP broadband network is connected with the SIP RAN platform, and the cellular ultra-small mobile base station is connected with the IP broadband network; and the overground monitoring console is connected with the SIP RAN platform. The adoption of the structure can lead the real-time control system to use the IP protocol to carry out connection through the existing ADSL, LAN and other broadband circuits of a user, and the connection of the remote end from the IP network to a mobile network is realized by a special gateway. The real-time control system can seal signal coverage in the environment, be economic, be convenient to carry and reduce the radiation.
Description
technical field [0001] The invention relates to a real-time control system for underground mobile communication and monitoring in coal mines, in particular to a real-time control system for mobile communication and monitoring in underground coal mines connected by an IP broadband network between an underground information collection system and a ground monitoring system. Background technique [0002] Coal is the most important energy source in our country, but the situation of safety production in coal mines is not optimistic. Coal mine safety accidents occur frequently, which not only cause huge economic losses, but also cause extremely bad social impacts. The backwardness of underground communication and monitoring technology in coal mines, especially mobile communication and monitoring technology is one of the important reasons for frequent accidents. [0003] At present, the main forms of mobile communication in mines include power carrier communication, leaky wireless c...
