Intelligent detection equipment for defects of ammeter

Abstract

The invention relates to intelligent detection equipment for defects of an ammeter. The intelligent detection equipment comprises an infrared communication interface, a high-definition camera, an image detector and an embedded processor, wherein the infrared communication interface is used for transmitting a testing signal to the detected ammeter, so that the detected ammeter can conveniently control a display screen of the detected ammeter to display a testing character string in the testing signal; the high-definition camera is used for photographing the display screen of the detected ammeter so as to output a testing image; the image detector is connected with the high-definition camera and is used for carrying out image processing on the testing image, identifying a character string in the testing image and outputting the character string as an identification character string; and the embedded processor is connected with the image detector and is used for comparing the identification character string with the testing character string so as to determine whether a defect alarming signal is transmitted or not. With the adoption of the intelligent detection equipment for the defects of the ammeter, the display defect detection of the display screen of each ammeter can be completely automatically realized, so that the manual cost and time cost are reduced.

Description

[0001] This invention is a divisional application of a patent with the application number 201510100771.2, the application date is March 8, 2015, and the invention name is "Intelligent Meter Defect Detection Equipment". technical field [0002] The invention relates to the field of power supply equipment management, in particular to an intelligent detection equipment for electric meter defects. Background technique [0003] 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. [0004] The information of the electricity meter is mainly conveyed through its display screen. During the production process of electric met...

Problems solved by technology

[0005] 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 equipment have poor versatility, and it is difficult to formulate reasonable testing procedures

[0006] Therefore, a new electric meter defect detection equipment based on electronic detection is needed to replace the complex and inefficient manual detection method, transform the existing electronic detection equipment with poor compatibility, and quickly and efficiently complete the detection of display defects of various types of electric meters
