A HDV Acquisition and Process Solution for Mine Black Environment

For the problems that bad imaging result, small adapt range of optical and can´t work under the low light intensity mine environment in the existing solutions and products, we proposed a HDV acquisition, process and wireless transmit ion solution that accords with the intrinsically security standard for the low light intensity environment, including two aspects: HDV acquisition front-end and mine media data process terminal. The HDV Acquisition Front-end used the technology of low light night vision with the white light assistant illumination that coupled the image intensifier and CMOS image sensor module directly; Multimedia data process terminal under mine takes the S3C6410 based on ARM11 as the CPU to achieve the video signal process and wireless transmit ion following the Wi-Fi and Mini USB communication protocols. Ground on this solution, we designed the mine Media data process system that the Power part used the low voltage design, which fulfilled the intrinsically safe standard and came out the low power of device. The test results showed that this system can implement the high-definition video images collection, compression and storage within the scope of illumination 10^-4 ~ 10² Lux.
