Abstract

The invention relates to the technical field of gas safety detection equipment, in particular to a gas concentration detector and a control method thereof. The gas concentration detector comprises a gas monitoring hardware system, a signal transmission module and a control system, wherein the control system is connected with the gas monitoring hardware system through the signal transmission module to control the gas monitoring hardware system and receive data information from the gas monitoring hardware system; the gas monitoring hardware system comprises a gas acquisition module, a gas pretreatment module, a drain module, a power module and a gas detection module; the control system comprises a circuit control module and an upper computer module. According to the gas concentration detector, a monitoring point can be selected according to a practical requirement, the concentration of gas in an inspection well can be monitored on line in real time, the gas concentration detector has intelligent sampling, water-gas separation, flow monitoring control and drain functions, the concentrations of multiple kinds of gases can be monitored at the same time, and whether a gas pipeline leaks or not can be judged in real time.

Description

technical field [0001] The invention relates to the technical field of gas safety detection equipment, in particular to a gas concentration detector and a control method thereof. Background technique [0002] The underground gas pipeline is usually surrounded by a soil layer. When the gas leaks from the gas pipe, it will diffuse into the surrounding space through the soil layer. Natural gas leakage caused by pipeline cracks generally does not form a high-pressure jet stream, and the leaked gas will diffuse into adjacent pipelines, accumulate in the pipeline and gradually reach the explosion limit, so the detection of gas concentration in underground pipelines should be strengthened. [0003] At present, the pipelines are all closed with manhole covers, and the inside of the pipeline is in an equal pressure state. The gas will diffuse in the pipeline to both ends, gradually reach the wellhead, accumulate gradually and continue to spread forward. [0004] Considering the diff...
