Example Embodiment

[0066] Example 1.

[0067] A device for the detection method of substance content based on color data analysis, including a sample container and a colorimetric card 1 (such as figure 2 Shown), shooting and viewfinder, intelligent identification terminal, the colorimetric card 1 includes a color block area 2 and a sample placement area 5 in it, and three positioning points 4 are provided on the edge of the color block area 2 on the colorimetric card 1,

[0068] The shooting viewfinder and the intelligent identification terminal are smart mobile devices, such as smart phones or tablet computers, which are used to take pictures of the colorimetric card 1 area, perform color balance processing on the pictures, and can distinguish between the excellent block 3 and the sample position, The color data of the sample and the color data of color block 3 are identified from the picture, and the color block that is closest to the color data of the sample is compared. The content of the substan...

Example Embodiment

[0095] Example 2.

[0096] The method of the present invention can also be used to detect the concentration of specific ions in the solution, such as the concentration of hydrogen ions or hydroxide ions in the solution, that is, the pH value, and the color development on the pH test paper is used to identify the pH value of the solution.

[0097] An intelligent device for accurately identifying the pH of a solution, including precision pH test paper, colorimetric card 1 (such as image 3 Shown), shooting viewfinder, intelligent identification terminal, colorimetric card 1 includes color block area 2 and sample placement area 5. There are three positioning points 4 on colorimetric card 1,

[0098] Preferably, the photographing and framing device and the intelligent identification terminal are smart phones, tablet computers, etc.,

[0099] Preferably, a colorimetric card placement base can be added. The base is connected to a smart phone, a tablet computer, etc. through a fixed bracket,...

Example Embodiment

[0131] Example 3.

[0132] For the detection of the content of colored substances in solids or gas mixtures, it is necessary to pre-treat the solids or gases. For example, in the solid mixture, first ensure that the solid color is uniformly mixed, and take a quantitative mixture into a fixed-shaped sample container or press it. Tablet processing, and then put the sample container together with the mixture or the compressed tablet of the mixture into the sample area 5 to be tested;

[0133] For gas mixture, inject the gas to be tested into a fixed, airtight sample container and seal it, and then put the sample container containing the mixed gas into the test object placement area;

[0134] After the above-mentioned processing, it can be connected with the device and operation method of a substance content detection method based on color data analysis in Embodiment 1, and will not be repeated.

Abstract

The invention belongs to the field of content detection of color-changed substances, and specifically relates to a substance content detection method, system and devicebased on color data analysis. According to the technical scheme, the method mainly comprises the following steps: S1, creating a standard sample color database; S2, selecting color data corresponding to a certain amount of standard samples according to a detection result accuracy demand, and printing a plurality of color blocks; S3, shooting and frame the to-be-detected samples and the plurality of color blocks in onesame horizontal plane; S4, recognizing the color blocks inthe color the most close to the color data of the to-be-detected samples; and S5, finding out the substance content corresponding to the color blocks from the standard sample color database, and then defining to be the substance content in theto-be-detected sample. With the adoption of the method, the problems that a colourimetric card is used for visually comparing the color in case of little color difference, subjective factors highly influence the result, and the visual color difference comparing capability is limited, can be solved; the detection process is objective; the detecting accuracy is high; the field detection is convenient; the detection cost is low; and the result is accurate and clear.

Description

technical field [0001] The invention belongs to the field of substance content detection that produces color changes, and in particular relates to a substance content detection method, system and device based on color data analysis. Background technique [0002] For the detection of colored substances in liquid samples, a spectrophotometer test instrument can be used. For example, in the detection method of formaldehyde concentration, the national standard adopts adding formaldehyde to phenol reagent and then carrying out color reaction, and then detects the absorbance of colored substances in the solution through a spectrophotometer, and obtains the content of colored substances according to the absorption spectrum curve, thereby calculating the formaldehyde concentration. However, this method requires a specific spectrophotometric device, and there are problems such as complicated operation and calculation process, high dependence on the instrument during the use process, ...
