Embodiment

[0055] According to the analysis and research on the problems existing in the prior art, in order to improve the working efficiency of the verification process, reduce the errors caused by human factors, and reduce the uncertainty, the present invention re-plans and designs the whole set of verification devices. First of all, it is found in the analysis and research that the temperature field stability and fluctuation of the standard constant temperature bath have a great influence on the detection process, and the temperature control process and stability directly affect the stability and fluctuation of the temperature field, so the present invention combines touch screen technology and Combining the precision temperature control technology with the standard constant temperature bath, we design and manufacture a set of standard constant temperature bath precision temperature control program, which reduces most of the manual operations; secondly, in addition to the design of the...

Abstract

The invention brings forward a detection identification method of a standard constant temperature bath glass thermometer. The method comprises the following steps: step 1, obtaining a fuzzy image of a character to be identified in the glass thermometer; step 2, performing contour fuzzy feature extraction on the character to be identified; and step 3, performing fuzzy closeness identification processing on the fuzzy image of the character to be identified so as to identity the character. According to the technical scheme provided by the invention, incomplete characters on the glass thermometer are identified by use of a fuzzy closeness algorithm which is brought forward lately, the identification correct rate is about 96%, and the thermometer reading accuracy can reach 95%.

Description

technical field [0001] The invention relates to a verification and identification method for a glass thermometer used in a standard constant temperature tank. Background technique [0002] At present, the technical level and existing problems of the standard constant temperature bath verification glass thermometer at home and abroad: [0003] 1 Domestic technical level of standard constant temperature bath [0004] At present, the standard constant temperature baths used by domestic production enterprises and measurement and testing institutions all use traditional temperature instrument control methods. From the perspective of scientific and technological novelty search and information retrieval, domestic scientific research institutions and colleges and universities have researched and published some papers and books on touch screens, precision temperature control systems, automatic detection technologies and standard constant temperature baths. For example: (1) In the N...
