Description
PLM-driven equipment full life cycle ledger dynamic synchronization method and system Technical Field The invention belongs to the technical field of industrial internet software and equipment management, and particularly relates to a PLM-driven equipment full life cycle account dynamic synchronization method and system. Background In the device full lifecycle management process of an industrial enterprise, a Product Lifecycle Management (PLM) system is typically used as a core platform for a design phase to store structural information, component parameters, and complete BOM design data for a device. However, after a device is put into operation, its operating status, maintenance records, and fault information are typically recorded by a separate device management system, or by an operation and maintenance person manually maintaining a ledger. Because the systems used in the design stage and the operation and maintenance stage are independent of each other, a data linkage mechanism is absent between the two, so that the 'design data and the operation and maintenance data are mutually disjointed' has become a common problem in the prior art. In the prior art, because the PLM system and the operation and maintenance system are mutually independent, the equipment design data and the operation data are lack of a linkage mechanism, so that the equipment ledger is required to be updated in a manual mode after the design is changed, the updating period is usually as long as 2 to 3 days, input errors are easy to generate, the ledger data are difficult to accurately reflect the real state of the equipment, meanwhile, the design structure data, the operation state information and maintenance records are stored in a scattered manner, and a unified data chain penetrating through the whole process of design-operation and maintenance is lacking, so that the equipment is difficult to trace the sources in time when the performance abnormality or quality problem of the equipment occurs, and further, the operation and maintenance end is not capable of forming an effective decision based on the whole life cycle information of the equipment because the design reference and the operation and maintenance behavior are not capable of being compared in real time, and the improvement of the digital level of the equipment management is severely restricted. In summary, the prior art lacks a technical solution capable of automatically associating and dynamically synchronizing device design data and device operation stage data in a PLM system, and lacks a software system capable of implementing design-manufacturing-operation-maintenance full-flow traceability when a device is abnormal. Therefore, a new technical solution is needed to be developed to realize the dynamic updating of the equipment ledger and the process data tracing, so as to overcome the technical pain in the prior art.
