Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, reagent paper detected by employing color sensor of the present utility model one to one device and inspection
Survey method is described in detail.
As it is shown in figure 1, reagent paper is detected device by a kind of employing color sensor of the present utility model one to one, including: set
It is equipped with the test strips 2 of several indicator paper blocks 1, the electricity of acquisition component 3 for gathering indicator paper block 1 reflection intensity data is installed
Road plate 4, the number of described acquisition component 3 is identical with the number of described indicator paper block 1, and one_to_one corresponding is arranged, and each adopts
Collection assembly 3 is all to be made up of, between described test strips 2 and circuit board 4 LED 31 and a color sensor 32
Each LED 31 being additionally provided with on locating circuit board 4 and color sensor 32 and prevent the lamp of LED 31
Light irradiate color sensor 32 every tabula rasa 5.
As shown in Figure 2 and Figure 3, described it is respectively formed with on tabula rasa 5 and each LED on described circuit board 4
31 corresponding through holes 51 for embedding described LED 31 and with each color sensor on described circuit board 4
The 32 corresponding draw-in grooves 52 for embedding described color sensor 32, the number of described through hole 51 and draw-in groove 52 is with described
Circuit board 4 on the number of acquisition component 3 identical.
The described LED 31 distance away from described color sensor 32 is enough near, makes the color sensor 32 will not again
Receive the light of LED 31.Therefore, the described periphery of the through hole 51 of corresponding same group of acquisition component 3 on tabula rasa 5 with
It is 0.5~5mm that the base of draw-in groove 52 is separated by nearest distance, i.e. each LED 31 and adjacent color sensor 32 it
Between thickness to be passed through be 0.5~5mm separate every tabula rasa.
Ultimate range between described acquisition component 3 and corresponding indicator paper block 1 is:
Wherein, X is the distance between LED and indicator paper block 1;T is length or the minimum dimension of alleviating distention in middle-JIAO of reagent paper;θ is LED
Lighting angle.So that the light that LED 31 is got impinges upon on indicator paper block 1 completely.According to LED 31 rising angle
With the big I of indicator paper block 1 calculates the ultimate range between indicator paper block 1 and LED 31 and color sensor 32.
If LED 31 lighting angle is 30 degree, indicator paper block 1 size is 4*4mm, its LED 31 and color sensor
Distance between 32 and indicator paper block 1 is calculated as 7.5mm by above-mentioned formula.
