[0127] Through the digital QC manager control module, according to the specific needs during the overhaul period, the professional QDR overview unit, various types of QDR distribution unit, QDR distribution unit, overall QC witness point situation control unit, key QDR control unit, and QC witness point control unit in the control module are used respectively. Through these 6 specific units, the QDR data in the power plant work order system are extracted in real time, the number of key QDRs (defects caused by S-class and A-class equipment), the number of key QDRs in progress, completed, and awaiting approval are extracted, the data of each professional QC witness point in the power plant management system is extracted in real time, and the on-site witness data of H, W, and R points in the past two days are extracted.

[0128] Step 2: Summarize, count, classify, and identify the data for analysis, and propose rectification requirements and corrective measures based on the corresponding principles, and implement various action items. The corresponding principles are, for example, by classifying the types of QDR into 6 major types (A, B, C, D, E, and F), wear, deformation, aging, etc. are downgraded to Class A; non-compliance with design specifications and work documents is classified as Class B; operation beyond the design conditions is Class C; improper human operation, disassembly and assembly of equipment not in accordance with procedures, etc. are Class D; historical defects are Class E; other reasons are Class F. According to this classification principle, the QDRs generated during the overhaul are classified, and then some QDRs are focused on. For example, the main cause of Class D QDR is human error, and the responsible department needs to analyze the cause and formulate measures to prevent human error.

[0129] Through the digital QA manager control module and the digital QC manager control module, the data extracted from each unit in the digital QA manager control module and the digital QC manager control module are summarized, counted, classified, and identified according to the corresponding professional, importance, management requirements, time requirements and other judgment rules, and intuitively displayed through curves, summaries, bar charts, etc., and provide navigation and link functions.

And focus on tracking, rectification, and summarization. Real-time tracking of the handling of quality defects of key equipment is carried out, and timely intervention and correction are carried out.

[0130] Step 3: Analyze and warn of problems found in quality supervision and equipment quality defects based on the data, and promptly notify the responsible departments to make rectifications and advance the work.

[0131] After analyzing the data extracted from each unit in the digital QA manager control module and the digital QC manager control module, prompts and early warning functions are provided according to the importance, and the relevant responsible departments are notified in time for follow-up processing (if there are S-level and A-level equipment quality defects, the responsible director and section chief will be notified directly by mobile phone text messages and emails to remind the relevant responsible departments to pay attention and take action in time. In addition, the responsible departments and supervisory departments can query the details of quality supervision and quality control, track the rectification progress of quality supervision and quality control, and feedback the progress of relevant processing to various regular meeting materials of overhaul through the control module to further promote the progress of work.

[0132] The present invention obtains the original data of the power plant's relevant data system, extracts important information, and summarizes the quality supervision and quality control data that need to be collected and counted during the overhaul into the digital QA manager management and control module and the digital QC manager management and control module in the overhaul management system. By establishing various management and control units, the quality management problems that arise during the overhaul are classified and controlled, the implementation of quality supervision and quality control during the overhaul is tracked in a timely manner, and data statistics, data navigation, processing progress reminders, early warning functions, etc. are provided.
