Problems solved by technology

[0004] In the prior art, manual inspection is mainly used to detect the display defect of the electric meter reported for repair. There are many inspection procedures, and the steps that inspectors need to input are complicated. The accuracy and efficiency of inspection are not high. Due to the complex types of electric meters and the difficulty of display defect detection, these existing electronic testing equi...

Embodiment Construction

[0017] The implementation of the smart meter defect detection device of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] Ammeters are widely used and are the most basic metering terminals for power supply management departments to manage users' electricity consumption. Every electricity user needs to install an ammeter to measure their electricity consumption in real time. Therefore, the demand for ammeters is particularly large. The market for ammeters Also very active.

[0019] Common electric meters on the market can be classified in the following ways: (1) by use: industrial and civil meters, electronic standard meters, maximum demand meters, multi-rate meters; (2) by structure and working principle: inductive (mechanical), static (electronic), electromechanical (hybrid); (3) according to the nature of the power supply: AC meter, DC meter; (4) according to the accuracy level: commonly used ordinary meters: 0.2S, ...

Abstract

The invention relates to an intelligent detection method for defects of an ammeter. The method comprises the following steps: (1) intelligent detecting equipment for the defects of the ammeter is provided, wherein the detecting equipment comprises an infrared communication interface, a high-definition camcorder lens, an image detector and an embedded processor, the infrared communication interface is used for sending a testing signal to a detected ammeter, so that the detected ammeter controls a display screen to display a testing character string included in the testing signal; the high-definition camcorder lens is used for shooting the display screen of the detected ammeter so as to output a testing image; the image detector connected with the high-definition camcorder lens is used for processing the testing image so as to distinguish the character string in the testing image and output the distinguished character string; the embedded processor connected with the image detector is used for comparing the distinguished character string with the testing character string so as to determine whether a detect warning signal is given out or not; (2) the equipment is used for detection.

Description

technical field [0001] The invention relates to the field of power supply equipment management, in particular to an intelligent detection method for electric meter defects. Background technique [0002] Ammeter, short for watt-hour meter, is an instrument used to measure electric energy, also known as watt-hour meter, fire meter, electric energy meter, and kilowatt-hour meter. The electric meter is the metering equipment used by the power supply management department to detect the electric energy used by each power-consuming unit or individual, and is the basis for charging each power-consuming unit or individual. [0003] The information of the electricity meter is mainly conveyed through its display screen. During the production process of electric meters, it is inevitable that there will be defects in the display screen or processing equipment or transmission equipment, which will cause the display of the display screen to fail to meet expectations and have defects, whic...
