Description

Technical Field

[0001] The utility model relates to the technical field of laboratories, in particular to a solution image comparison system that is convenient for color comparison. Background Art

[0002] Colorimetry is a commonly used method in biochemical testing. It is based on the color reaction of generating colored compounds and determines the content of the component to be tested by comparing or measuring the color depth of the colored substance solution. As early as the beginning of the Christian era, the ancient Greeks used gallnut solution to determine the iron in vinegar. In 1795, the Russians also used gallnut alcohol solution to determine the iron in mineral water. However, colorimetry as a quantitative analysis method began around the 1830s and 1840s.

[0003] The theoretical basis of colorimetry is the relationship between the color of a substance and light. Light is an electromagnetic wave, which is naturally composed of electromagnetic waves of different wavelengths (400-700nm) in a certain proportion. Combined light can be decomposed into a continuous visible spectrum of red, orange, yellow, green, cyan, blue, purple and other colors through a prism. If two lights are mixed in an appropriate proportion to produce a white light sensation, the colors of the two lights are complementary to each other. When white light passes through a solution, if the solution does not absorb light of various wavelengths, the solution will have no color. If the solution absorbs some of the wavelengths of light, the solution will show the color of the remaining part of the light after passing through the solution.

[0004] The commonly used visual colorimetric method is the standard series method, which uses a group of colorimetric tubes of equal diameter and volume made of exactly the same glass material, and adds different amounts of standard solutions of the components to be tested in sequence, and then adds equal amounts of color developers and other auxiliary reagents, and then dilutes to a certain volume to make it a standard color scale with gradual color change. Then take a certain amount of the solution of the component to be tested in a colorimetric tube, use the same method to develop the color, and then dilute to the same volume. Compare this sample color solution with each colorimetric tube of the standard color scale to find the standard colorimetric tube with the color depth closest to the sample color solution. If the color of the sample solution is between the colors of two adjacent standard colorimetric tubes, the concentration of the sample solution should be the average of the concentrations of the solutions in the two standard colorimetric tubes. The main advantages of the standard series method are simple equipment and easy operation. The colorimetric process is easily affected by the experimental site and the position of the experimenter to produce color differences, and the experimental efficiency is low when multiple samples are tested.

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 The utility model provides a structural schematic diagram of an image comparison system which is convenient for color comparison. DETAILED DESCRIPTION

[0017] In order to better illustrate the purpose, technical solutions and advantages of the present invention, the present application will be further described below in conjunction with specific embodiments.

[0018] Example 1

[0019] The present embodiment provides an image comparison system that is convenient for colorimetry. The system includes a colorimetric area 1 and an experimental area 2, a partition wall 3 is arranged between the colorimetric area 1 and the experimental area 2, a color sensor probe 11 and a solution image display board 12 are arranged in the colorimetric area 1, the solution image display board 12 is a double-layer board and an image window 121 is opened on the upper layer board, and the color sensor probe 11 is used to identify the color signal in the image window 121 and send the color signal to a computer for analysis. The experimental area 2 includes a shooting unit 21, an operating table 22, and a light source 23. The operating table 22 is transparent, and a transparent container 3 contains a solution to be colorimetric and is placed on the operating table 22. The light source 23 is arranged below and on one side of the operating table 22, and ensures that the light is vertically incident on the transparent container 3. The shooting unit 21 simultaneously obtains the solution image directly above and on the side of the transparent container 3, and the solution image is finally displayed on the solution image display board 12. The color sensor probe 11 is an RGB photodiode color sensor probe or a wavelength feedback color sensor probe.

[0020] Because there are many water pipes and waterways during the solution color development experiment, and sometimes the color development experiment needs to be heated and other processing links, resulting in high water vapor content in the laboratory environment, which is not conducive to the use and maintenance of expensive color analysis equipment. At the same time, the environment with high water vapor content will retain condensed water on the container wall, affecting the visual judgment of the liquid after color development. Therefore, the utility model sets a separation wall 3 to isolate the water vapor in the colorimetric area 1 and the experimental area 2. The separation wall can be an independent laboratory or a glass room, a whole wall, etc., and can be processed according to the situation of the experimental site. Further, the shooting unit 21 uses an industrial camera to shoot the solution image, and takes pictures in the corresponding direction of the transparent container 3 through mobile facilities such as a pan-tilt platform. The industrial camera is electrically connected to the computer to receive the solution image, and the computer then displays the solution image to the solution image display board 12 through a projector connected by a signal, and the standard color card information is stored in the computer for auxiliary color signal analysis. Preferably, an outer cover, such as a light shield, is set at the camera head of the industrial camera to ensure that it is not affected by water vapor and room lights during shooting.

[0021] Generally, the edge of the container in the solution image is lighter in color and closer to the background color (usually white), which can easily cause color transition and affect the accuracy of colorimetry, especially for solution samples with low concentration or after dilution. Therefore, the solution image of each sample includes a top view and a front view. In addition, the window area of ​​each image window 121 is controlled to be smaller than the edge of the solution image. When performing colorimetric analysis, only the color area of ​​the solution is retained and the edge area of ​​the container in the image is not displayed to avoid the influence of the edge image and the background. Preferably, multiple image windows 121 are set and evenly distributed in the solution image area. Multiple samples are displayed simultaneously in different image windows to improve the efficiency of colorimetric analysis.

[0022] The utility model provides a solution image comparison system which is convenient for colorimetry, isolates an experimental area 2 from a colorimetric area 1, reduces colorimetric errors caused by environmental factors and the positions of experimenters, switches solution image information in the image area, separates the two stages of experiment and colorimetry, shortens the test cycle, and improves the experimental efficiency of solution sample colorimetry.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
