Description
Technical Field
The utility model relates to a detecting instrument especially relates to an on-line measuring instrument based on RGB tricolor visual sensor.
Background
The colorimetric method is a method for measuring the concentration of a colored substance contained in a solution by comparing the shade of the color of the solution with visible light as a light source. Two types of colorimetric methods are commonly used: visual colorimetry and photoelectric colorimetry. The common visual colorimetry is a standard series method, that is, different amounts of standard solutions of an object to be measured are put into a group of identical colorimetric tubes, and color development is carried out according to the analysis steps to prepare a standard color gradation with gradually changing color. The sample solution is developed under the same condition, and compared with the standard color gradation, the standard with the most similar color is visually found out, and the content of the component to be measured in the sample is calculated and determined according to the amount of the standard solution contained in the standard solution. The photoelectric colorimetry measures the absorbance of a series of standard solutions on a photoelectric colorimeter or a similar structure, plots the absorbance to the concentration, draws a working curve, and then finds the concentration or the content of the solution of the component to be measured on the working curve according to the absorbance of the solution of the component to be measured. Compared with a visual colorimetry, the photoelectric colorimetry eliminates subjective errors, improves the measurement accuracy, and can eliminate interference by selecting an optical filter, so that the selectivity is improved.
At present, the on-line detection of the concentration of a colored substance generally adopts the working principle of photoelectric colorimetry, and is carried out by adopting the colorimetry principle of traditional monochromatic light, different light sources are required to be selected for reagents with different colors, the work of replacing the light sources is complicated and professional, and different optical filters are required to be selected to eliminate interference; the electrode needs to be in direct contact with a reagent solution, so that the electrode is passivated, the maintenance of the electrode is complicated and professional, the electrode needs to be replaced for 1 time about 1 year in order to ensure the precision of a detection instrument, the price of the electrode is high, and the maintenance cost is high.
According to the Grassmann's law, any color can be generated by mixing three colors (three primary colors), which can be selected but must be independent of each other, i.e. any primary color cannot be obtained by adding and mixing the other two primary colors, the red (R), green (G) and blue (B) primary colors are most commonly used at present, and the number of the three primary colors required in the color scheme becomes the tristimulus value. The color matching equation is: c (R + G + B) ═ R (R) + G (G) + B (B); if the light to be measured is monochromatic light with a certain wavelength, the corresponding R, G, B value is called as the spectral tristimulus value and is represented by r, g and b. The international commission on illumination (CIE) in 1931 established tristimulus values for matching isoenergetic spectral colors based on the average of the experimental results of color matching in w.d.wright and j.guild, and thus established a color system whose values are determined only by the visual characteristics of the human eye, and thus the following formula can be obtained: CIE 1931-RGB chromaticity system, whose values depend only on the visual characteristics of the human eye. C λ ═ r (r) + g (g) + b (b). The color detection is realized by measuring the reflection ratio of the three primary colors of the solution color, and the reaction end point is confirmed, namely the corresponding solution concentration value can be calculated through the used solution volume.
Therefore, the utility model discloses an online detection instrument based on RGB three primary colors vision sensor is very meaningful in being applied to the titration analysis and detection.
