Problems solved by technology

[0002] At present, there are parts made of plastic for the external circuit breaker of the electric energy meter. This plastic part is exposed to the air for a long time, and it is easy to age after being exposed to the sun. As a result, the exposed plastic parts of the external circuit breaker of the electric energy meter may have appearance defects, such as Defects such as cracks, chromatic aberrations, air bubbles, pores, weld marks, sink marks, material flow marks, silver threads, white marks, variegated spots, napping, flash, uneven color, warping, delamination, damage, etc.; manual search is time-consuming strenuous

Embodiment 1

[0044] As shown in the figure, this embodiment provides a detection system for exposed plastic parts of electric energy meters, including a chassis, a test platform, an image acquisition device, an angle adjustment device, a bar light source, a processor, a mounting frame, a linear slide, and a hand wheel ;

[0045] The linear sliding table is arranged on the upper part of the cabinet, and an image acquisition device is arranged on the inside of the upper part of the cabinet, and the image acquisition device is arranged on the linear sliding table. The image acquisition device is connected with the processor, and transmits the captured image to the processor; the bar-shaped light source is arranged in the chassis to provide illumination light when the image acquisition device captures the image of the exposed plastic parts of the electric energy meter; the electric energy meter is exposed The plastic part is set on the test platform; the angle adjustment device is set on the l...

Embodiment 2

[0061] The detection system for the exposed plastic parts of the electric energy meter provided in this embodiment is composed of two parts: a hardware system and a software system. Analysis and processing.

[0062] Among them, the detection system for exposed plastic parts of the electric energy meter is mainly composed of a chassis shell 1, a test platform 2, an electric energy meter 3, a bar light source 4, a camera 5, a linear slide table 6, and a computer 7, etc., such as figure 2 As shown, the chassis shell is mainly composed of aluminum plates, sealed on all sides, and one side can be opened to protect the identification system hardware and block ambient light. A camera is placed on the top of the case for collecting images, the camera is connected with the computer, and the captured images are transmitted to the computer. LED strip light sources are placed on the left, right, front, lower sides of the camera to provide lighting. Below is the test platform where the ...

Abstract

The invention discloses an electric energy meter exposed plastic piece detection method. The method comprises a step of obtaining an image of an electric energy meter exposed plastic piece, a step of conveying the image to an image processor, a step of carrying out preprocessing to obtain a binarization image, a step of obtaining a characteristic signal of the electric energy meter exposed plastic piece, and a step of comparing a characteristic signal and a standard characteristic signal to obtain a difference, judging the difference and emitting an alarm signal. The invention provides an electric energy meter exposed plastic piece detection system which detects an exposed plastic piece of an electric energy meter external circuit breaker, through the system, whether the exposed plastic piece of the electric energy meter external circuit breaker has defects or not can be automatically identified, in this way the artificial detection of the appearance of each external circuit breaker can be reduced, and the working efficiency is improved. The multi-angle shooting of the exposed plastic piece of the external circuit breaker is carried out, and then the image analysis is carried out through host software to judge whether the exposed plastic piece has defects.

Description

technical field [0001] The invention relates to the field of electric energy meters, in particular to a method and system for detecting exposed plastic parts of electric energy meters. Background technique [0002] At present, there are parts made of plastic for the external circuit breaker of the electric energy meter. This plastic part is exposed to the air for a long time, and it is easy to age after being exposed to the sun. As a result, the exposed plastic parts of the external circuit breaker of the electric energy meter may have appearance defects, such as Defects such as cracks, chromatic aberrations, air bubbles, pores, weld marks, sink marks, material flow marks, silver threads, white marks, variegated spots, napping, flash, uneven color, warping, delamination, damage, etc.; manual search is time-consuming strenuous. [0003] Therefore, a detection system for exposed plastic parts of electric energy meters is needed. Contents of the invention [0004] The objec...
