Intelligent inspection system and method for urban gas pipe network

Abstract

The invention discloses an intelligent inspection system and method for an urban gas pipe network. An external gas leakage detection system comprises an infrared detection unit, a sensing unit, a GPS positioning unit, a central processing unit, a leakage signal alarm unit, a base station transmitting unit, a satellite receiving unit, a cloud processing unit, a transmission unit, a data sharing unit, an uploading unit and terminal equipment. The invention relates to the technical field of gas monitoring. According to the intelligent inspection system and method for the urban gas pipe network, when gas leakage occurs at the joint between pipelines, the infrared detection unit is used for detecting surrounding gas and the GPS positioning unit is used for positioning the leakage site, so that the leakage condition is known quickly, the probability of danger is reduced, and the problems that the phenomenon of gas leakage is likely to occur at the connecting position between pipelines of gas, an existing inspection vehicle is adopted for monitoring, the efficiency is low, and the leakage situation cannot be reported at the first time are solved.

Description

technical field [0001] The invention relates to the technical field of gas monitoring, in particular to an intelligent inspection system and method for an urban gas pipeline network. Background technique [0002] Natural gas refers to a kind of combustible gas existing in nature, which is a kind of fossil fuel, including gas formed by various natural processes in the atmosphere, hydrosphere, and lithosphere (including oil field gas, gas field gas, mud volcano gas, coal bed methane and biogas, etc.). The definition of "natural gas" that people have used for a long time is a narrow definition from the perspective of energy, which refers to the mixture of hydrocarbon and non-hydrocarbon gases naturally stored in the formation. In petroleum geology, it usually refers to oil field gas and gas field gas. Its composition is mainly hydrocarbons and contains non-hydrocarbon gases, so it burns to produce yellow or blue flames. Natural gas is stored in underground porous rock format...
