Automatic Verification System for Pointer Meters and Simple Digital Meters

Abstract

The present invention relates to an automatic verification system for a pointer meter and a simple digital meter, which includes a calibration meter; also includes a meter calibration driving device and an image acquisition device, and the meter calibration driving device drives the calibration meter to indicate the required position or The corresponding value is displayed, and the image recognizer receives the calibration image transmitted by the image acquisition device, and compares the calibration image with the standard image corresponding to the calibration instrument pre-stored in the image recognizer; when the calibration image and the standard image When the correspondence is consistent, the image recognizer transmits verification confirmation information to the meter calibration drive device; the meter calibration drive device reads the calibration drive signal loaded to the calibration meter according to the verification confirmation information, and the meter calibration drive device stores and outputs the calibration drive signal . The invention can realize the effective verification of the pointer meter head and the simple digital meter head, has high degree of automation, wide application range, and is safe and reliable.

Description

technical field [0001] The invention relates to a verification system, in particular to an automatic verification system for a pointer meter head and a simple digital meter head, belonging to the technical field of meter verification.
