KBA12H intrinsically safe infrared camera for mining
The KBA12H intrinsically safe infrared camera for mining is suitable for use in places with gas and coal dust explosion hazards underground in coal mines.
Product Overview
The KBA12H intrinsically safe infrared camera for mining is suitable for use in places with gas and coal dust explosion hazards underground in coal mines. This camera is a key equipment in the coal mine industrial television system for real-time image monitoring of major production processes, important equipment, and key positions, using Ethernet transmission. This camera has a compact structure, small size, light weight, explosion-proof, earthquake resistant, and moisture-proof properties.
Infrared automatic fill light
Equipped with infrared automatic fill light function, it can present high-quality monitoring images under low illumination, with a minimum illumination of ≤ 0.05lx and horizontal clarity of ≥ 400 lines.
Voice Intercom
The camera integrates intercom handles, speakers, and other intercom broadcasting equipment, integrating camera, intercom, and transmission to achieve image monitoring and intercom for key positions in coal mines.
data conversion
It can convert the collected real-time images into Ethernet optical signals and Ethernet electrical signals for output, with high transmission efficiency and long transmission distance.
Working Principle
Optical imaging and signal conversion
External light enters the lens through a glass window, focuses on the CCD chip, converts the light signal into an electrical signal, outputs a full TV signal, and completes image acquisition and preliminary conversion.
Video signal processing and transmission
-
After the entire TV signal is denoised and enhanced by the video processing circuit, it is converted into an optical signal by the wireless video transmitter and transmitted to the receiving end through fiber optic or wireless channels to ensure real-time and low latency images.
Network video output and remote monitoring
The optical signal is compressed into a digital signal by a network video encoder and output to the monitoring system through wiring terminals. It supports remote real-time viewing and storage, achieving visual monitoring of the underground environment.
Structural Composition
housing
Made of 304 stainless steel; Ability to resist corrosion, explosion, rust, and impact.
CCD device
High sensitivity, strong light resistance, anti-interference, and low distortion; Small size, long lifespan, and vibration resistance.
wireless transmitter
Wireless video transmitter with strong adaptability; Long transmission distance, modular design.
lens
Optical lens, explosion-proof glass.
Project Case
Guonuo weighing equipment has been successfully applied to multiple domestic and foreign enterprises and has gained widespread recognition
Production Process
Guonuo Technology adopts internationally leading production processes and equipment to ensure stable and reliable quality
Infrared intelligent fill light
Integrated infrared LED array and photosensitive sensor, automatically triggers fill light under ≤ 0.05lx illumination, combined with high-sensitivity CCD chip to ensure ≥ 400 line clarity, achieving high-definition monitoring of underground dark light environment.
Integrated audio and video intercom
Equipped with a built-in intercom handle and high fidelity speaker, the camera, intercom, and data transmission are integrated through a noise cancelling microphone and audio processing chip, supporting real-time voice interaction for key positions in coal mines.
Dual mode high-speed transmission
Adopting Gigabit Ethernet optical/electrical dual interfaces, the video encoder converts images into optical signals (single-mode fiber transmission ≥ 10km) or electrical signals (RJ45 interface), supports full duplex communication, and ensures efficient long-distance data transmission.
Modular compact structure
The lens, solid-state CCD device, and wireless transmission module are integrated into the explosion-proof housing, and the camera transmission is integrated through precision assembly technology. The structure is compact and impact resistant, suitable for installation in narrow underground spaces.
