AI Technical Summary

Technical Problem

Existing technologies lack multi-state consistency verification for the same workpiece or weld in pipeline prefabrication projects, resulting in delayed production node judgment, duplicate scheduling of inspection tasks, omission of rework status, failure to promptly incorporate re-inspection results into release judgment, and misjudgment of quality release conditions, thus affecting the integrity and reliability of closed-loop management of production quality.

Method used

A project master database is constructed with the workpiece list and welding list as unique indexes. Status compatibility analysis is performed through workpiece code and weld code to generate timestamped version snapshots, synchronously update the status of production nodes, and coordinate abnormal statuses in a closed loop to achieve dynamic correlation between workpiece status, weld status and production process status.

Benefits of technology

Ensure that the judgment of the same workpiece or weld status is synchronized across all business nodes, avoid duplicate inspections, omissions in rework, or misjudgments in release, improve the integrity and reliability of closed-loop management of production quality, and reduce the risk of delayed judgments at production nodes and untimely adjustments to shipping plans.

Abstract

This invention discloses a project master data-driven closed-loop management method for production quality in pipeline prefabrication, relating to the field of pipeline prefabrication project quality management technology. The method constructs a project master database with a workpiece list and a welding list as unique indexes, and performs state compatibility analysis on various data in the pipeline prefabrication project based on workpiece codes and weld codes to obtain project master data. When the status of a workpiece or weld changes, the project master data undergoes state matching verification and a timestamped version snapshot is generated to update the corresponding production node status and monitor its effectiveness. When an anomaly occurs, the status of the workpiece, weld, and quality are coordinated in a closed loop. Based on the closed-loop coordination results, closed-loop status analysis is performed to identify abnormal process statuses and generate production quality closed-loop management results. This achieves multi-state consistency verification and data-driven synchronous flow for the same workpiece or weld status, ensuring the consistency of status at production, inspection, rework, and release nodes.
