[0002] As a key facility for transporting media, pressure pipelines play an important role in the petroleum, chemical, and electric power industries. Since they are subjected to a variety of loads during operation, such as gravity, internal pressure, wind load, etc., as well as thermal expansion and contraction and additional displacement of connected equipment, stress monitoring of pipelines is crucial. Real-time collection and transmission of pipeline stress parameters are of great significance for ensuring safe operation of pipelines and preventing accidents.
