■ Overview
Mine flameproof camera is a new type of digital camera developed by our company for the special environment of coal mines. This product has all the functions of ordinary explosion-proof digital cameras and focuses on solving the problem that coal mining underground working faces are not suitable for optical fiber transmission of digital signals. It is well known that there are gangs, roof fall, and frequent equipment movement in the mining face of coal mines. Although optical fiber has many advantages such as high digital signal transmission rate and no code loss, there are also fear of bending, squeezing, Fatal shortcomings such as fragility and difficulty in recovery processing, so the video digital signal in the mining face is not suitable for optical fiber transmission, and the digital signal transmission of the network cable has the shortcomings of short transmission distance and high code loss rate. In order to solve the problem of digital signal transmission in the coal mining face, our company has invested a lot of energy to develop this new type of explosion-proof digital camera for transmitting digital signals over a long distance with ordinary mining cables, which completely solves the digital mining face of the coal mine. The problem of signal transmission "last mile".
