Description

Workpiece traceability coding predictive fault tolerance and dynamic reconstruction system oriented to flexible production line Technical Field The invention relates to the technical field of automobile part production, in particular to a flexible production line-oriented predictive fault tolerance and dynamic reconstruction system for workpiece traceability coding. Background In the modern manufacturing industry, especially in the field of automobile part production, the flexible production line is widely applied because of the advantages of being capable of flexibly adapting to production of various products and rapidly adjusting production rhythm. The flexible production line realizes the efficient production of various and small-batch products by integrating various processing equipment and processes, and meets the demands of the market on product diversification and individuation. However, the complexity and dynamics of flexible production lines also present significant challenges to production management, where accuracy and reliability of workpiece traceback encoding is one of the key issues. In the production process of the flexible production line, the workpiece tracing code is an important means for realizing the transparency, quality control and problem tracing of the production process. The production state, the processing history and the quality information of the workpieces can be tracked in real time by carrying out unique coding on each workpiece and scanning code recording in each production link. However, in actual production, the code scanning process may fail due to factors such as equipment, environment, or tag identification. If the code scanning at the marking position fails, even if the quality of the workpiece is qualified, the workpiece can not be moved out of the production line due to incorrect identification, and the subsequent processing flow cannot be entered, so that the execution efficiency of a production plan is affected, unnecessary loss of the qualified workpiece can be caused, a corresponding code compensation mechanism is required to be established, and trace-back codes are newly given to the qualified workpiece when the code scanning fails, so that the workpiece can normally enter the production flow, and the continuity of production and the effectiveness of quality control are maintained. In addition, the dynamic nature of flexible production lines also requires a high degree of flexibility and fault tolerance from the traceability system. In the production process, the station sequence, processing equipment and the like may change due to production requirements, so that the traceability system is required to be capable of being dynamically reconstructed and is suitable for adjustment of a production line. However, conventional traceback systems often lack such flexibility and fault tolerance, and once a sweep failure or production adjustment occurs, the system is difficult to automatically repair and adjust, resulting in discontinuities and errors in the production data.
