The invention provides a smart re-check management and control method used for a low voltage meter reading system which belongs to the field of power utilization. The method utilizes the re-check principle based on mode analysis to improve the accuracy of anomaly judgment, narrow the re-check range and improve the re-check efficiency. Based on a meter reading data analysis result, a set copy-core copy deviation analysis and reason identification method and a multi-dimensional set copy quality management and control index system are used, and through data pretreatment, set copy data defect judgment, new user judgment, total score mismatching judgment, anomaly preliminary judgment and secondary judgment of set copy anomaly, the to-be-checked, to-be-core-copied, and charge-off user list of the current period is finally produced. By anomaly reason identification, the re-check range is narrowed, the re-check efficiency is improved, and comprehensive monitoring of each link of the set copy service and improvement of the set copy quality are facilitated. The method can be widely used in the field of design, operation and management of power utilization and supply set copy systems.
