Mining high-definition video collecting system and method

Abstract

The invention discloses a mining high-definition video collecting system. The mining high-definition video collecting system comprises a video collecting unit, an auxiliary light source and an intrinsic safe power source. The auxiliary light source is used for providing a supplementary light source for the video collecting unit when the exterior brightness is low. The intrinsic safe power source is connected with the video collecting unit and the auxiliary light source and used for providing electric energy for the video collecting unit, starting the auxiliary light source when the brightness is lower than the set value and providing electric energy for the auxiliary light source. The video collecting unit comprises an optical lens, and further comprises an MCCD image sensor, a digital signal processor and video output, all of which are sequentially connected with the optical lens. The invention further discloses a collecting method. The scheme that the MCCD image sensor is combined with an infrared laser tube to serve as the auxiliary light source is adopted, high-definition video collection can be achieved under the total dark environment, the intrinsic safety principle is met, the overall power consumption of equipment is low, the weight is light, the size is small, cost is low, and maintaining is easy and convenient.

Description

technical field [0001] The invention belongs to the technical field of video acquisition, and relates to a mine-used high-definition video acquisition system and method. Background technique [0002] In recent years, due to insufficient video monitoring in dark places such as mines, some faults have not been discovered in time and caused accidents. Using mine-used low-light video acquisition equipment can obtain high-definition video in low-light or even dark environments The image is convenient for discovering hidden danger points in time. [0003] The existing mining video acquisition equipment is bulky and cumbersome. The current solution uses a CCD image sensor combined with an array of infrared LED auxiliary lighting. It is often used to increase the number of infrared to obtain a clearer video image, which increases power consumption and is difficult. Later maintenance, in addition, the price is more expensive. Contents of the invention [0004] The purpose of the ...
