Abstract

The invention relates to an instrument for identifying the color of a liquid culture medium. The instrument comprises a detection device, light sources, a detection plate, a touch display screen, a control panel and an instrument shell, wherein the light sources are vertically fixed at two ends of the detection device and directly face the through hole of the detection device. The touch display screen is fixed to the upper part of the instrument shell and used for displaying the user interface and interaction, and the control panel is fixed to the bottom plate of the instrument shell. According to the technical scheme, the chromaticity of the liquid culture medium can be tested, naked eye observation is replaced and the accuracy and the consistency of liquid culture medium color interpretation can be remarkably improved.

Description

technical field

[0001] The invention relates to an identification instrument, in particular to an instrument for color identification of liquid culture medium, and belongs to the technical field of detection structure equipment. Background technique

[0002] An acid-base indicator is usually added to the colored liquid medium. When the microorganisms in the medium grow, acid will be produced, which will cause the pH of the medium to decrease, thereby changing the color of the acid-base indicator in the medium. The growth of microorganisms in the medium can be judged by observing the color of the medium. At present, the color of the liquid medium is generally observed with the naked eye and compared with the color card. There are differences in the recognition and judgment of color changes by each observer, and the observation results vary from person to person, leading to inaccurate or even wrong conclusions. Therefore, it is necessary to design a color recognition device ...

Examples

Embodiment 1

[0034] Embodiment 1: see figure 1 , an instrument for color recognition of liquid culture medium, said instrument comprising a detection device, a light source vertically fixed at both ends of the detection device and facing the through hole of the detection device, a detection board 2, a touch screen 8, a control panel 9 and The instrument shell 7 and the touch screen 8 are fixed on the upper part of the instrument shell 7 for displaying user interface and interaction. The control board is fixed on the bottom plate of the instrument shell, and the touch display screen is arranged on one side of the instrument shell.

[0035] The detection device is fixed on the bottom plate of the instrument shell and is made of black phenolic plastic. A round hole with a proper depth for accommodating the sample bottle is processed directly above it. The round hole is the sample position of the instrument. The through hole passing through the diameter of the above-mentioned circular hole ve...

Embodiment 2

[0040] Example 2: see figure 1 , a detection method for an instrument for liquid culture medium color recognition, said method comprising the following steps:

[0041] Step 1) In the instrument start-up stage, the instrument turns off the light source after the user takes out the sample position sample, and at this time, the detection board is started to collect the intensity of light with input wavelengths of 465nm, 525nm, and 615nm, which is recorded as the background value [B 0 ,G 0 , R 0 ];

[0042] Step 2) Then the instrument turns on the light source for a specific time, at this time, the detection board is started to collect the intensity of light with input wavelengths of 465nm, 525nm, and 615nm, which are recorded as the basic calibration value [B 1 ,G 1 , R 1 ];

[0043] Step 3) After the user puts the liquid culture medium to be measured in the sample position, the instrument turns on the light source for a specific time, collects the intensity of light with i...
