High-temperature pipeline strain monitoring system and method

The invention belongs to the technical field of strain monitoring, and particularly relates to a high-temperature pipeline strain monitoring system and method. Comprising a strain acquisition module, a temperature acquisition module, a data acquisition unit and an upper computer, the strain acquisition module comprises three strain measurement elements and a strain compensation element, the temperature acquisition module comprises a temperature measurement element, and the strain acquisition module and the temperature acquisition module respectively acquire strain data and temperature data. The data are uploaded to an upper computer through a serial port bus for data storage and data real-time display, and the three strain measuring elements, the strain compensation element and the temperature measuring element are fixed on the high-temperature pipeline in a welding mode. The method has the advantages that the defects of a method for fixing by pasting glue in a high-temperature environment can be effectively
