Mine Explosion-proof Ordinary Cable Ultra-high-speed Camera

Mine Explosion-proof Ordinary Cable Ultra-high-speed Camera

■ Overview
The mine explosion-proof camera is a new type of digital camera developed by our company for the special environment of coal mines. This product is equipped with ordinary explosion-proof digital cameras.At the same time, it focuses on solving the problem that the mining face of coal mine is not suitable for optical fiber transmission of digital signals. It is well known that there are fragments.
The ceiling falls and the equipment moves frequently. Although optical fiber has many advantages such as high transmission rate of digital signals and no code loss, there are also fears of bending, squeezing, and easy Fatal shortcomings, such as difficulty in processing interruption and recovery, so it is not suitable to use optical fiber transmission for video digital signal of mining face, and there is transmission of digital signal transmitted by network cable.Short distance, high bit loss rate and other shortcomings. In order to solve the problem of digital signal transmission in coal mining face, our company invested a lot of energy to develop this general mine.
The new type of mine explosion-proof digital camera with long-distance cable transmission of digital signals completely solves the problem of the "last mile" of digital signal transmission in underground mining face problem.

■ Features
● With optical port, electrical port, long-distance electrical port and other transmission methods;
● Long-distance electrical port transmission adopts ordinary four-core mining cable transmission (if the camera is installed with a power supply, a two-core cable can be used for transmission). The distance can reach more than 1km, and the enhanced type can reach more than 2km;
● The long-distance electrical port transmission mode can be connected to other digital transmission equipment (such as telephones, automatic remote control substations, etc.) without adding cables;
● The diagram of long-distance transmission is as follows:
