Embodiment 1

[0070] The present invention mainly includes a light source, a computer (installed with the software of the present invention), a splint, a video camera (or a camera), a constant temperature tank, a shading plate, and storage for interactive data (hard disk, mobile or network) and other parts. The present invention selects the light environment mainly according to the characteristics that the blue LED light source can reduce light refraction, light shadow and light reflection. The present invention has also designed the image acquisition device of the liquid-in-glass thermometer according to the original machine vision, and the image collected by the device is transmitted to the computer equipped with the data acquisition software part of the present invention through the data line, and the software of the present invention is used on the computer to first Carry out image preprocessing and scale, number recognition, etc., and then store the preprocessed image and recognized num...

Embodiment 2

[0087] When the user of the present invention utilizes the integrated structure to carry out the automatic detection of the liquid-in-glass thermometer (as image 3 ), will not involve the problem of data transmission through the network or transfer through mobile storage, the data collection software and data analysis and processing software are installed on the same computer, and the external database is only used for saving data.

[0088] The functions and functions of each part are as follows:

[0089] Such as image 3As shown, the constant temperature tank 5 is equipped with a stirring motor 1, which is to stir the liquid in the constant temperature tank 5 when the temperature rises to ensure the uniformity of temperature changes in the tank. The constant temperature tank 5 is equipped with splints 4 and 4 Mainly used to fix all the thermometers 3, the liquid-in-glass thermometers 3 (standard and tested liquid-in-glass thermometers) are inserted into the splint, the whit...

Abstract

The invention discloses an automatic detection device for liquid glass thermometers. A stirring motor (1) is mounted on a thermostatic tank (5), a clamp plate (4) is arranged on the thermostatic tank (5), liquid glass thermometers (3) are inserted on the clamp plate (4), a white back light plate (2) is mounted behind the clamp plate (4), a lens of a camera (8) faces the liquid glass thermometers (3), the camera (8) is mounted on a camera support (9), a light source (6) is mounted on a light source support (7) and adjusted by a computer (10), the camera (8) is electrically connected with the computer (10) through a data transmission line, data of the computer (10) are electrically connected with a computer (13) for analyzing data through a network or a mobile storage (6), and the computer (13) is electrically connected with a printer (12). According to the automatic detection device, a plurality of liquid glass thermometers can be detected automatically, and can be connected smoothly and operated and used singly, and the automatic detection device can be transplanted conveniently and can automatically detect the liquid glass thermometers with stable performances.

Description

technical field [0001] The invention relates to a thermometer verification device, in particular to an automatic verification device capable of simultaneously performing multiple glass liquid thermometers. Background technique [0002] The verification of liquid-in-glass thermometers is the basic work in the thermal engineering testing of the metrology department. Because of its low cost, simple process, intuitive reading, simple operation and high measurement accuracy, glass liquid thermometers are mass-produced and widely used in industrial production, medical treatment, etc. education and research activities. In order to improve the data reliability of the thermometers used, various users send them to the metrology department for verification and calibration every year. The 2010 list of large and medium-sized industrial enterprises in the province released by the Hunan Provincial Bureau of Statistics included 1,525 enterprises (272 in Changsha). thermometers, in accorda...
