Research on Intelligent Archiving System of Energy Meter Based on Image Recognition
At present, the provincial metrological verification center is developing towards intelligent, unmanned, and highly relia-ble. However, the manual maintenance method is still adopted in the electrical energy metering equipment arrival ar-chiving. Therefore, based on the characteristics of the main parameters of the energy meter file being engraved on the surface of the meter and the relatively fixed position, the research of intelligent file archiving technology based on im-age recognition was carried out. An improved vertical projection based on the feature region matching method and the Otsu method was proposed. Histogram method and language model-based post-identification method of electric ener-gy meter parameter string. The above-mentioned technology is used to develop an intelligent energy meter archiving system, which realizes the functions of automatic identification and archiving of single-phase meter and three-phase meter parameters. Through experiments, it is verified that the smart metering system can accurately locate, segment and identify the parameters of the filing, and provide theoretical and practical guidance for the popularization and application of metering equipment intelligent filing.
