In order to better complete the data collection and recording work of the operation, distribution and commissioning connection, a visual data collection method for on-site marketing operations of power supply enterprises is studied. According to the established visual data acquisition standards, a visual data acquisition interface is designed, and fuzzy clustering method is used to calculate the membership degree of data samples in the acquisition interface, adjust and correct partial data, and distinguish data sources; Compare the common data in each system, calculate the data consistency rate of each device, and determine whether all visual data in each system meets the consistency requirements, thereby completing the visual data collection. The experimental demonstration and analysis results show that the visual data acquisition results can provide a reliable basis for the analysis of abnormal line loss fluctuations in the substation area, and the data consistency rate of multiple devices is 100%, with good data acquisition quality.
