Intelligent auxiliary device for electric energy meter verification fault judgment

Abstract

The invention discloses an intelligent auxiliary device for electric energy meter verification fault judgment. The auxiliary device is installed on an electric energy meter verification table which is provided with a plurality of electric energy meter intelligent verification modules for automatically verifying an electric energy meter. The auxiliary device comprises an industrial camera, a moving mechanism which drives the industrial camera to move and enables the position of the industrial camera to correspond to the front surface of a calibrated electric energy meter on the electric energy meter intelligent calibration module, an infrared triggering module used for sending out a signal after the position of the industrial camera corresponds to the front surface of the calibrated electric energy meter on the electric energy meter intelligent calibration module so as to lighten a liquid crystal screen of the electric energy meter and trigger the industrial camera to acquire an image of the liquid crystal screen of the electric energy meter, and a fault code identification module used for identifying a fault code in the electric energy meter liquid crystal screen image acquired by the industrial camera. The appearance fault judgment time is shortened, and the electric energy meter verification efficiency is improved.

Description

technical field [0001] The invention relates to electric meter verification technology, in particular to an electric energy meter verification device. Background technique [0002] At present, the electric energy meter verification laboratories of power supply companies in various cities are mainly responsible for the verification of the dismantled old electric energy meters, which is an important link to ensure fairness, justice and legality of electric energy measurement work. The "Administrative Measures for the Sorting and Disposal of Dismantled Smart Energy Meters" released by the State Grid Corporation of China in 2018 put forward new requirements for the disposal and management of dismantled electric energy meters. The energy meter verification laboratory of the city company has put forward higher requirements. [0003] At present, the energy meter verification laboratories of power supply companies in various cities are mainly responsible for the verification of use...

AI Technical Summary

Problems solved by technology

With the increasing number of watt-hour meter inspections, the manual judgment mode has exposed many defects such as high probability of misjudgment and missed judgment, long time consumption, etc.:

[0004] 1. There are many types of faults in dismantling and returning the electric energy meter. The probability of misjudgment and misjudgment of manual judgment of appearance faults is high. Two additional procedures of verification and re-inspection are required to ensure the accuracy of manual appearance inspection, resulting in an increase in the length of verification.

[0005] 2. The inspection quantity of the dismantled electric energy meter is large, and the unqualified number of appearance inspection accounts for more than 90% of the total unqualified. The inefficient manual judgment mode needs to continuously prolong the working time, which consumes a lot of labor and time costs

[0006] The traditional verification method of electric energy meters has largely restricted the laboratory to provide efficient legal measurement services for electric power customers.
