Embodiment

[0055] The invention provides a comparison system and method for electric energy meter components, and the specific process is as follows:

[0056] (1) Put the energy meter on the workbench, adjust the moving speed of the workbench, set the reference XY point, adjust the resolution of the CCD camera and the brightness of the LED light source.

[0057] (2) The CCD camera scans and detects the PCB board of the electric energy meter on the workbench, and completes the detection of the electric energy meter process and the identification, pins, and installation positions of components.

[0058] The CCD camera unit detects the PCB board from five directions: top, front, rear, left, and right; the high-speed and high-resolution CCD camera unit is used to capture the typical characteristics of the energy meter components; four-color coaxial LED light source The unit is used to supplement light when shooting for the CCD camera unit.

[0059] (3) The X-ray detection unit scans and det...

Abstract

The invention relates to an electric energy meter component comparison system and a method thereof. The system comprises an image acquisition module, a motion control module, an image processing module and a workbench, wherein the image processing module is connected with the image acquisition module; the motion control module is moved on the workbench. The method comprises the following steps of: (1) placing an electric energy meter on the workbench; (2) carrying out scanning detection; (3) transmitting scanned images to an image identification unit; (4) extracting characteristic values and transmitting the characteristic values to a data processing unit; (5) and carrying out data processing and comparison. The invention can realize the automatic saving and comparison of components of the electric energy meter. The invention adopts a transmission mode of a servo motor unit and ball screw components, improves the positioning accuracy, and can ensure the accurate moving of workbench locations. The invention adopts the image processing model of high accuracy, and compares components of the electric energy meter with electric energy meter components in an image library.

Description

technical field [0001] The invention belongs to the field of electric equipment feature recognition, and in particular relates to a system and method for comparing electric energy meter components. Background technique [0002] With the promotion and popularization of smart electric energy meters, its quality directly affects the accuracy and reliability of electric energy metering, which is related to the interests of thousands of households. If the components that make up the smart energy meter fail, it will seriously affect the quality of the whole machine, resulting in frequent accidents. Before use, the electric energy meter needs to pass the verification of the verification department before it can be used. Not only its measurement performance must meet the requirements, but its safety and reliability must also be guaranteed. When the electric energy meter manufacturer supplies in large quantities, there will be component replacement problems caused by insufficient su...
