the step 2 comprises the following steps: the pipeline welding seam is divided into a negative film and a non-negative film, the negative film enters a welding seam negative film digital management system, the welding seam negative film is judged to correspond to completion data, if the negative film and the completion data are not matched, false film and wrong film unmatched welding seam information are screened out, and then recording is carried out; if the two are matched, the pipeline digital management system judges whether the welding line is abnormal according to a high back fruit area around the pipeline and a third-party construction environment, if the welding line is abnormal, excavation verification is carried out, the result after the excavation verification is further judged whether the welding line is acceptable, the acceptable verification result is monitored in real time, and the unacceptable verification result is repaired; if no welding seam abnormality exists, the pipeline digital management system monitors in real time; for the pipeline welding seam without the negative film, a pipeline digital management system is required to judge whether the welding seam is abnormal or not according to an internal detection signal; if the welding seam is abnormal, performing excavation verification, further judging whether the result after the excavation verification is acceptable, performing real-time monitoring on the acceptable verification result, and repairing the unacceptable verification result; if no welding seam abnormality exists, the pipeline digital management system monitors in real time;
step 3, rechecking an internal detection signal of the welding line without the negative film on the basis of rechecking the abnormal internal detection of the welding line with the negative film, finding out the welding line with the abnormality, and performing excavation verification, wherein if the safety operation condition is not met after the excavation, the welding line is repaired in time;
the method realizes intelligent evaluation after digitalization of a weld joint nondestructive testing negative film, performs comprehensive analysis and evaluation by combining completion data, internal and external testing conditions, surrounding environment data, high consequence area data, stress conditions, geological disaster data, parallel pipeline data and stray current interference data, solves the problem of data island, performs deep mining utilization, comprehensive analysis and evaluation of big data, combines and aligns the weld joint negative film and pipeline digital information with the existing pipeline digital management system, GIS data management system, cathode protection management system, pipeline strain monitoring system and internal testing data comparison analysis digital system, and realizes interaction and utilization of data; the concrete points are as follows: firstly, aligning the nondestructive testing negative films and the welding lines, and screening out black openings, namely, the welding lines are provided with negative films and black films, the negative films are provided with welding lines and are not provided with welding lines or redundant negative films, so that huge work which cannot be carried out manually before is made up; secondly, intelligent evaluation of the welding seam negative film is realized, on one hand, errors caused by manual film evaluation or film evaluation differences caused by technical irregularity are avoided, on the other hand, the working efficiency is greatly improved, and only spot check and recheck are needed; thirdly, alignment analysis is carried out on the internal detection data and the external detection data, mutual verification is carried out, management is improved, the recognition and quantification level of the internal detection on the welding seam defect signals is improved, and the recognition rate of the abnormal internal detection signals of the circumferential welding seam is improved; aiming at the welding seam without a negative film or the pipe section with missing data, the defect of safety risk is analyzed and screened out by combining the detection data and the big data, the intrinsic safety of the pipeline is improved, and the safe and reliable operation is ensured.
