[0002] Oil and natural gas play an important role in people's production and life. Oil and gas pipelines are the least limited and most suitable means of transporting oil and its products. However, since the oil and gas in the pipeline are flammable and explosive, in order to ensure safety during transportation, it is necessary to monitor the pressure of the oil and gas pipeline.

[0003] Traditional pipeline leak detection methods are usually based on pressure sensors to collect pressure signals in the pipeline, and determine whether the pipeline is blocked or has a leak through pressure changes. When the instruments installed on the pipeline detect safety hazards such as pipeline leakage, blockage, explosion, etc., the staff can go to the site in time to inspect and handle the oil and gas pipeline to ensure the normal operation of the oil and gas pipeline.

[0004] However, most of the existing monitoring devices are usually installed on the surface of the pipeline when in use. Since most of the pipelines are laid in the outside world, the monitoring instruments are exposed to the outside world for a long time and are exposed to wind and rain for a long time. The surface is prone to rust and the inside is prone to damage. Manual maintenance is often required, causing great economic losses and consuming a lot of labor. Utility Model Content
