Refrigeration pressure pipeline safety monitoring system and monitoring method

The invention relates to the technical field of pipeline monitoring, in particular to a safety monitoring system and method for a refrigeration pressure pipeline. Comprising a wall thickness acquisition module, a welding seam monitoring module, a thinning analysis module, a welding seam analysis module and an evaluation module, and the wall thickness acquisition module is used for acquiring the wall thickness of the refrigeration pressure pipeline; the welding seam monitoring module is used for monitoring a welding seam on the refrigeration pressure pipeline; the thinning analysis module is used for comparing and judging whether the position has a thinning risk or not based on the acquired pipeline wall thickness position and the pipeline wall thickness allowable value of the position; the welding seam analysis module selects a corresponding judgment analysis method based on the types of welding seam defects and judges whether the welding seam has defect risks or not based on the welding seam defect sizes; an
