Method and system for judging consistency of metering device based on pattern recognition

Abstract

The invention discloses a method and a system for judging the consistency of a metering device based on pattern recognition. The method comprises: collecting images of different parts of an inspectedammeter by an industrial microscope; conveying the collected images to a determination system for image processing; acquiring and storing feature signals of binary images and the images of the different parts of the inspected ammeter into a database as standard feature signals of ammeters of the inspected batch; obtaining feature signals of images of different parts of a delivered ammeter or an onsite ammeter of the same batch as the inspected ammeter; and comparing the feature signals of the delivered ammeter or the onsite ammeter with the standard feature signals stored in the database to obtain the similarity, and determining the delivered ammeter or the onsite ammeter is an ammeter as same as the inspected ammeter according to the similarity. The method provided by the invention can automatically identify that whether the ammeter delivered by the ammeter supplier and the inspected ammeter are in the same batch and whether the onsite ammeter installed on the user site is artificially replaced, thereby reduce the manual workload, and improving the working efficiency.

Description

technical field [0001] The invention relates to the technical field of measuring equipment, in particular to a method and system for determining the consistency of measuring equipment based on graphic recognition. Background technique [0002] With the rapid development of smart grids and the wide application of big data analysis and processing of power consumption information collection, the methods of stealing electricity in power consumption information collection systems are becoming more and more intelligent and concealed. With the development of high-tech and network-based electricity theft, electricity theft that modifies and destroys the metering method occurs from time to time. Inconsistency, but at present, power companies often face the problem of difficulty in obtaining evidence when they discover the electricity theft, which is not conducive to the later processing of the electricity theft and the recovery of electricity bills. In the face of the current severe...
