[0002] At present, the measurement and recording of data such as wellhead pressure and temperature in oil and gas fields mainly rely on manual on-site reading and recording with various instruments and other equipment. However, due to the different measuring devices in different parts, each well inspection often requires carrying multiple measuring equipment, and there are many measuring points, which greatly increases the labor intensity of the staff. Moreover, in remote oil and gas fields, the distance is long and a lot of inspection time is required.

[0003] In addition, it is impossible to continuously monitor data such as pressure and temperature. Once abnormalities in wellhead pressure and temperature occur, they cannot be discovered in time, which brings great safety hazards to the normal operation of the oil field and may even cause serious property losses.

[0004] Nowadays, in order to accelerate the development of the Internet of Things and digitalization in oil fields and further improve the Internet of Things and digitalization of products, it is urgent to deploy Internet of Things systems in oil and gas fields, especially large or remote oil and gas fields, to realize the automatic collection and remote transmission of temperature and pressure data and meet the needs of wireless collection.
