The mine intrinsic safety type wireless camera provided by the invention has the advantages that the problem of inconvenience in mounting and moving in a wired transmission manner is solved, and cost is saved; flexibility of image monitoring is enhanced; a camera shooting function under low illumination level can be realized; and continuity of image display is realized, and higher display quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of monitoring equipment for mines, and in particular relates to an intrinsically safe wireless camera for mines. Background technique [0002] Coal is an important basic energy in my country. The existing energy endowment structure makes coal account for about 70% of my country's primary energy consumption structure. Due to the limited production conditions of coal mines, historically, among the industrial sectors of various countries, the accident fatality rate of coal mines is the highest. 95% of the production capacity of my country's coal mines is underground mining. With the increase of mining depth, there are more and more factors affecting safe production, and the conditions are becoming more and more complicated. Because of the special environment of coal mining, the coal mining industry has always been a high-risk industry in my country's industrial and mining enterprises. Relevant departments of ...

AI Technical Summary

Problems solved by technology

At present, the cameras widely used in coal mines are all connected by wires. There are problems such as long-distance wiring workload, high cost, and image acquisition is limited by distance. Especially because of the special environment of coal mines, the transmission of wired signals is easily interfered and the system failure rate High, maintenance and repair are inconvenient; in addition, the image switching time of the existing cameras is relatively long, generally about 1s (second), which makes the image switching have obvious pauses, which seriously affects the monitoring quality
