Problems solved by technology

[0002] Coal mines and other operating environments are harsh and accidents are prone to occur. Using the video surveillance system, ground monitoring personnel can directly and real-time monitor the underground situation, not only can intuitively monitor and record the safety production situation of the underground work site, but also timely discover hidden dangers of accidents , prevent problems before they happen, and can also provide relevant first-hand image data for post-event analysis of accidents, so the video monitoring system is an important part of the modern mine safety production monitoring system; the wireless transceiver device in the existing video monitoring system, Most of the receiving range is limited, and the sensitivity is not high, it is very inconvenient to use
