Full-function detection system for electric energy meter

Abstract

The invention discloses a full-function detection system for an electric energy meter. The system comprises the electric energy meter, and the electric energy meter is provided with a liquid crystal display screen, a pulse lamp and a 485 communication module. The system comprises a detection device, and the detection device comprises a conveying belt, a short circuit detection unit, a liquid crystal display detection unit, a bar code scanning unit, a 485 communication detection unit, a pulse lamp detection unit, a switching-on and switching-off detection unit, a rejection unit and an upper computer. The electric energy meter is also provided with a bar code, and the electric energy meter is conveyed through the conveying belt and scanned through the bar code. The system can achieve the short circuit detection, liquid crystal display detection, 485 communication detection, pulse lamp detection, switching-on and switching-off detection, carrier detection and elimination to realize detection of the electric energy meter, and the detection is convenient and efficient.

Description

technical field [0001] The invention relates to an electric energy meter, in particular to an electric energy meter full-function detection system. Background technique [0002] At present, the electric energy meter basically adopts simple power-on tooling before leaving the factory, and the appearance, status and communication function of the electric energy meter are judged by the hand-held infrared detector and the human eye. That is, the operator manually puts the electric energy meter into the simple power-on tool, uses the PC host computer to test the 485 communication function, manually tests the infrared function with the infrared detector, judges whether the opening and closing is successful by manually listening to the sound, and judges the liquid crystal full display by the naked eye. And the appearance is qualified; the whole process is to manually take the table from the assembly line and put it into the tooling, and then manually put it back into the water line...

AI Technical Summary

Problems solved by technology

[0003] The traditional ex-factory inspection has great disadvantages in the actual testing process: the judgment of part of the function is completely dependent on human senses (listening to the sound of opening and closing the switch and judging the full display of the liquid crystal with the naked eye, etc.), and the test results are somewhat unreliable and missed. Due to the need for manual picking, the number of tests in a certain period of time is limited and the efficiency is low
