Mine flameproof hard disk video recorder is suitable for coal mine in explosive environment, mainly used to connect video images, for real-time monitoring and video recording of images, and video playback, video recorder built-in storage hard disk, supporting video storage time of more than 15 days; Hard disk video recorder (DVR) is the key equipment for real-time image surveillance and video recording of main production links, important equipment and key positions in the coal mine industrial TV system, which adopts optical cable or cable transmission; This video recorder has the characteristics of compact structure, small size, light weight, earthquake resistance, moisture resistance and so on.

Mine flameproof and inherent safety programmable control box is suitable for the coal mine with explosive dangerous gas and coal dust, mainly used in the coal mine drainage control, belt transport control, crusher control, emulsion ratio control, coal slime water treatment control, automatic loading machine control, hopper weighing ratio control and other automatic control devices, using imported programmable.

Flameproof and inherent safety type programmable electric control box for mine is suitable for underground coal mine with explosive dangerous gas and coal dust, mainly used in underground coal mine small pump control, belt transport control, crusher control, emulsion ratio control, coal slime water treatment control, automatic loading machine control, hopper weighing ratio control and other automatic control devices. Using imported programmable controller (PLC) as the core equipment, it has strong applicability, scalability, high reliability and strong communication ability. Its logic control mode can be realized by software programming, which makes the complex control logic simple and easy. There are reliable isolation measures and intrinsic safety power supplies between the input and output signals inside the control box, thus ensuring more flexible and universal connection and matching with various types of sensor actuators and various equipment electronic control circuits.
