Ltd.10.26689/jera.v5i6.2682ArticleDevelopment and Application of Methane Leakage Monitoring System for Gas Transmission Pipelinehttps://artdesignp.com/journal/JERA/5/6/10.26689/jera.v5i6.2682WangQijun,WeiShiqi2021562021-11-30Oil and gas pipeline transportation, as a relatively safe way of oil and gas transportation, undertakes most of the transportation tasks of crude oil and natural gas. Oil and gas pipeline accidents affect a wide range of consequences. Therefore, the oil and gas pipeline leakage detection is paid more and more attention. In this paper, ultra-low power methane gas sensor is selected to collect methane gas concentration in the air, and wireless network technology is used to build a wireless network sensor system with 4G function. Through the sensor distribution along the pipeline, it can intuitively and accurately judge whether there is a micro-leakage in the pipeline, and understand the diffusion situation after the leakage. The sensor system has high reliability and stability, and has high value of popularization and application.
