Method and device for testing electronic thermometer

Abstract

The invention relates to a calibration method of an electronic thermometer and a device thereof. The calibration method comprises the following steps: a starting step; a clamping step for fixing and moving the electronic thermometer to be tested according to requirements; a temperature field monitoring step for monitoring whether temperature parameters of a standard calibration temperature field meet calibration requirements; an image acquisition step for acquiring display value image of the electronic thermometer to be tested by an image acquisition device; a value judgment step for processing images and identifying value according to value images, and judging errors of the value identification result and the standard value; an exception processing step for processing exceptions (for example, a mechanical device can not run) according to the requirement during the calibration process; and an ending step for ending calibration of a batch of the electronic thermometers. A calibration device of the electronic thermometer comprises at least one thermostatic calibration source, a controller module, a driver module, a mechanical execution device module, an image acquisition module and a calibration system software module.

Description

technical field [0001] The invention relates to the technical field of measuring instruments, in particular to a verification method and device for digital display instruments. Background technique [0002] At present, in the verification of electronic thermometers, the method of manual interpretation is basically adopted. This method of manually reading and recording data has the problems of low work efficiency and prone to misreading, especially after the inspectors work for a long time. It is prone to eye fatigue, leading to misreading, false detection, and missed detection. This verification method has high labor intensity, low work efficiency, and low degree of automation, and the verification results are greatly affected by human factors. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention uses computer vision theory to solve the most critical numerical automatic interpretation problem in electronic thermometers,...
