The utility model comprises a housing body, a light source, a checkout cabin, a reflecting mirror, a charge-coupled device (CCD) camera and a culture dish. The utility model is characterized in that a matrix light source plate installed in a light source box is composed of 5 to 25 pieces of element matrix light sources. A power supply is connected with an LED through a dimming potentiometer. The matrix light source plate can be divided into zones, for example, 5 zone and 9 zone, to adjust the luminous brightness of the matrix surface light source of the LED to make the illumination intensity of the light source homogeneous, which is good for the CCD camera to obtain high quality image and improve the distinguishability of the measurer. The utility model is applicable to the microorganism measuring of antibiont medicine, environmental protection and cosmetic.
Description
The utility model relates to a kind of surveying instrument of cultivating microorganism in the ware of measuring.
The method of carrying out the titer of antibodies measurement both at home and abroad adopts the microbial detection method usually, its early stage surveying instrument is the projection ceremony, use one dimension CCD in conjunction with mechanical movement at present, obtain the instrument of analyte picture, as the automatic Measurement and analysis instrument of Chinese patent CN2160662Y microorganism, its principle is that the CCD scanning device obtains the analyte picture by mechanical movement, then image is carried out Treatment Analysis, used LED source only is suitable for scanner.Because scanner imagery must rely on mechanical movement to obtain image, has reduced the stability and the reliability of instrument.
The purpose of this utility model is a kind of microorganism survey meter of design, adopts the two-dimensional CCD video camera to adjust the front light source of brightness in conjunction with subregion.Exempt and fall mechanical movement, the light source luminescent face is adjusted to optimum regime,, improve stability, reliability, improve accuracy of detection to improve the adaptability of instrument to tested product.
The utility model is to realize like this.Adopt the two-dimensional CCD video camera, reach the lighting source through particular design, its lighting source all is better than other light source with quasi-instrument.Do not have the machinery motion and improved working efficiency.Its light source is made up of light source box, even light glass, support, front light source board, light adjusting potentiometer, current limiting device and photodiode, wherein the front light source board is placed on the light source bottom, the top layering of front light source board is placed with even light glass, it is characterized in that the front light source board is made up of 5～25 block unit matrix light sources, power supply is through light adjusting potentiometer and light-emitting diodes pipe coupling.
Below in conjunction with accompanying drawing and example the utility model is further specified.

Fig. 7 the utility model structural representation.
Referring to Fig. 7, Fig. 2, Fig. 3, but the utility model is a kind of microorganism survey meter with subregion degree of lightening front light source, comprise casing 11, light source 12, test storehouse 17, reflective mirror 14, CCD video camera 15, culture dish 13, wherein culture dish 13 places on the platform of light source 12, and reflective mirror 14 and CCD video camera 15 are installed in test 17 tops, storehouse; Light source 12 is made up of light source box 10, even light glass 8, support 9, matrix light source board 1, light adjusting potentiometer 6, current limiting device 5 and photodiode 3, matrix light source board 1 is placed on light source box 10 bottoms, the 1 top layering of matrix light source board is placed with even light glass 8, it is characterized in that matrix light source board 1 is made up of 5～25 module unit matrix light sources 2, power supply is connected with photodiode 3 through light adjusting potentiometer 6.
The luminous front that the used cell matrix light source 2 of the utility model is made up of 12～35 photodiodes 3.
The matrix light source board can be divided into a plurality of light modulations district on demand, adjusts brightness.Referring to Fig. 4～6, expression respectively, light modulation is divided into 25 districts, 9 districts and the three kinds of embodiment in 5 districts, and among Fig. 3, the n among the light adjusting potentiometer Wn represents the number of partitions, if be divided into 25 districts, then n is 25; If divide 9 to distinguish then n represents 9, promptly use 9 potentiometers.The connotation of the n of current limiting device Rn is identical.
Current limiting device can use current-limiting resistance or constant-current source device.
Matrix light source board 1 of the present utility model can be divided into 5～25 light modulation districts.
Referring to Fig. 7, synoptic diagram lighting source 12 of the present utility model is contained in microorganism detection instrument bottom, tested culture dish 13 places on the platform above the light source 12, carry out the entire image collection by computer 16 control ccd video cameras 15 by 14 pairs of culture dish of reflective mirror, by computer and special software image is analyzed, handled, draw report.
Adjust the dot matrix LEDs light source owing to adopted subregion, make illuminance more even, widened the instrument scope of application, this instrument is made be difficult to differentiate the identification easily that becomes of inhibition zone in the culture dish over, for some special bacterium circle, when contrast gradient more weak, when ccd video camera is difficult to differentiate, can adjust light intensity by integral body or subregion, improve the effect that image contrast reaches accurate measurement bacterium circle.After using this lighting source instead, the scope of application of titer of antibodies surveying instrument be can enlarge, and microorganism survey meter analysis to measure precision and working efficiency improved.
Light source in the utility model as shown in Figure 1, light source box is square, also can do circular or other shapes.
This microorganism survey meter is applicable to that the microbial medicine class detects, also can be in the microorganism detection of clinical medicine inspection, environmental protection, commodity inspection and cosmetics.
