Description

Technical Field

[0001] This utility model belongs to the field of methane detection, specifically relating to a methane monitoring device for underground pipeline networks. Background Technology

[0002] Methane is a colorless, odorless, flammable, and explosive gas. It poses significant safety hazards not only in coal mine operations and gas pipeline leaks but is also a major contributor to the greenhouse effect. Currently, the gas leak detection technologies used in the gas industry mainly include flame ionization detection, semiconductor detection, infrared detection, and laser detection. Laser detection technology is a relatively advanced gas detection technology both domestically and internationally. It is developed based on the principle of infrared absorption by methane molecules and typically uses a 1650nm laser as the detection laser. When the laser passes through methane gas, a portion of the laser light is absorbed by the methane, thus determining the methane concentration. Summary of the Invention
