Problems solved by technology

[0004] CN101426290A discloses a general wireless sensor network node device, but it is not perfect and the effect is not ideal
[0005] Although the research on wireless sensor networks is in full swing, the monitoring and management of energy transmission pipelines are still mainly manual.
In remote areas, the cost of data collection is high; when the amount of data is large, the cost of data management is large; there are many difficulties
In the pipeline transportation, there is a lack of a system that can realize automatic data collection and regular monitoring to ensure the safe operation of the pipeline
