Laser methane gas leakage detection device with photographing function and laser methane gas leakage detection method

Abstract

The invention relates to a photoelectric gas detection technology in the information technology, in particular to a laser methane gas leakage detection device with the photographing function and a laser methane gas leakage detection method. The laser methane gas leakage detection device with the photographing function is composed of a photographing module, a laser detection concentration module, a laser reflection board, an image display module, a power module, an alarm module and a central data storage. The invention further provides a data collecting method achieving on-site leakage point concentration and video images through the laser methane gas leakage detection device, on-site monitoring concentration and the video images of leakage points can be obtained, and data collection with synchronous monitoring on live environment methane gas concentration and the video images is achieved.

Description

technical field [0001] The invention relates to information technology, in particular to gas detection technology in optoelectronic technology. Background technique [0002] Methane is widely distributed in nature and is the main component of natural gas, biogas, oilfield gas and coal mine tunnel gas. Methane is a colorless, tasteless, and odorless gas that cannot be seen, touched, or smelled when mixed with air. When the concentration of methane in the air increases, the oxygen content in the air can be relatively reduced, which can suffocate people. When the methane content in the air reaches more than 40%, it can cause immediate death. In fresh air, when the concentration of methane reaches 5% to 16%, it reaches the explosive concentration, also known as the explosion limit. When the methane concentration is below 5%, it can burn when encountering a fire source, but cannot explode. When the methane concentration is greater than 16%, it cannot burn or explode when encoun...
