Description

Technical Field

[0001] The present invention belongs to the technical field of data quality management, and in particular relates to a method, system, terminal and medium for verifying data throughout the entire manufacturing process of power transmission and transformation equipment. Background Art

[0002] As a typical discrete industrial process with high complexity and high reliability requirements, power transmission and transformation equipment manufacturing requires data traceability, quality transparency and process controllability throughout the entire product process, which are becoming core technical demands.

[0003] Currently, the industry generally adopts a multi-system collaborative manufacturing model, including design systems, production execution systems (MES), quality management systems (QMS), equipment monitoring systems, etc. However, there are problems such as heterogeneous data sources, inconsistent semantics, lack of standards, and redundant records among these systems, which makes it impossible to directly integrate and apply data, especially forming an obvious bottleneck when performing quality inspection tasks.

[0004] The existing data verification model for power transmission and transformation equipment manufacturing still relies primarily on manual verification and static rule-based proofreading. While some companies have deployed some automated verification tools, these tools typically only support field-level validity verification and fail to perceive key quality factors such as semantic correlations between fields, process stage dependencies, and historical trend changes. This can easily lead to misjudgments and omissions, and even serious information silos, such as the same batch of data being processed repeatedly and mistakenly entered into the system. Furthermore, existing systems struggle to flexibly schedule verification rules in dynamic manufacturing environments and lack the self-learning capabilities to adapt to complex operating conditions.

[0005] The identification of abnormal data often relies on empirical thresholds or fixed templates, lacking intelligent algorithm support and being nearly incapable of processing high-dimensional, multi-channel, and multi-process data matrices. Furthermore, the lack of a unified and reliable data archiving mechanism makes it difficult to trace abnormal events, and risks such as data falsification and version confusion are difficult to address at the source. Summary of the Invention

[0064] (2) Before performing data quality verification, principal component analysis and isolation forest algorithm are introduced, and abnormal samples are identified by combining the covariance relationship between fields and structural characteristics. This effectively improves the recognition accuracy of complex problems such as nonlinear anomalies, isolated data points, and cross-field conflicts. It can assist the verification rules in filtering systematic deviations and random anomalies, significantly reducing the misjudgment rate and missed detection rate.

[0065] (3) By constructing a rule graph containing rule nodes and their contextual dependencies and introducing a rule activation mechanism based on the business state vector, the system can dynamically call a subset of matching rules for verification based on factors such as the current process, equipment status, and process segment, avoiding the problems of traditional systems such as "one-size-fits-all rules" or "static rules that are out of touch with reality", and improving rule adaptability and verification efficiency.

[0066] (4) Utilize the structured exception log mechanism and blockchain distributed storage to generate summary records with metadata such as timestamp, field location, and source device for all data that fails verification, and complete hash evidence and node signature verification on the chain to ensure that abnormal events are verifiable and non-repudiable in subsequent quality problem analysis, review, and supervision scenarios.

[0067] (5) After completing the quality check, a data quality report covering multiple indicators such as field compliance rate, abnormal thermal distribution, rule hit frequency, abnormal cluster type, etc. can be automatically generated, and visualized through the client interface in the form of charts, heat maps, indicator cards, etc., to assist management personnel to quickly locate the source of the problem and optimize the process flow, which has decision-making support value.
