Start key control test sample device 4 startsTest sample, and interrupt test sample process by break key having under abnormal conditions.
Preferably, described color sensor 21 adopts TCS230 color sensor.
Native system adopts TCS230 color sensor to carry out sample detection, and TCS230 is TAOS (TexasAdvancedOptoelectronicSolutions) colourama able to programme that company releases is to the converter of frequency. The face of tradition Urine AnalyzerLook identification all adopts amorphous silicon optical sensor, with the radiation source of three-colour filter or employing different wave length, logical at reverberation placeCross reverberation generation current on silicon optical sensor, through current/voltage-converted, voltage amplification, variable connector, AD conversion,Then sending into single-chip microcomputer processes. TCS230 color sensor is integrated three kinds of wave filters of RGB on one chip, canDirectly, by controlling the various combination of pin S2, S3, can select different wave filters, in improving certainty of measurement, make againDetection hardware is simpler. And TCS230 color sensor cost is low, performance good, is on market, to hold facile color sensor.Therefore as optimal way, color sensor adopts TCS230 color sensor.
TCS230 is integrated in configurable silicon photoelectric diode and current frequency converter on a single cmos circuit, withTime on one chip integrated three kinds of filters of RGB (RGB), when incident light projected TCS230 when upper, by photoelectricity twoThe various combination of utmost point management and control making pin S2, S3, can select different wave filters; Export not after frequency converter through overcurrentThe square wave (dutycycle is 50%) of same frequency, the square wave of the corresponding different frequency of different colors and light intensity; Can also determine by outputMark is controlled pin S0, S1, selects different output-scale-factors, reference frequency output is adjusted, to adapt to different needAsk. For TCS230, in the time of a selected color filter, it only allows certain specific primary colors to pass through, and stops otherPassing through of primary colors. For example: in the time selecting red filter, only have redness to pass through in incident light, blue and green is all hinderedOnly, so just can obtain the light intensity of red light; In like manner, select other wave filter, just can obtain blue light and green lightLight intensity. By these three values, just can analyze the color that projects the light on TCS230 sensor.
For avoiding color sensor test sample error larger, before testing, need TCS230 color sensor to carry out white balance tuneWhole. Theoretically, white is redness, green and blue the mixing by equivalent; But in fact, three former in whiteLook also not exclusively equates, and for the optical sensor of TCS230, it is not identical to the sensitiveness of these three kinds of Essential colour,Cause the RGB output of TCS230 unequal, therefore before test, must carry out blank level adjustment, make TCS230 to examineThree primary colors in " white " surveyed equate. Carrying out blank level adjustment is to prepare for follow-up color identification.
In this device, concrete steps and the method for blank level adjustment are as follows:
1, empty test tube is placed on to the top of sensor, a white light source is placed in the top of test tube, and incident light can be wornCrossing test tube is irradiated on TCS230.
2, according to the method introduced above, gating redness, green and blue electric-wave filter successively, record respectively redness, green andBlue value, then just can calculate 3 adjustment parameters that need.
3, timer being set is a set time (10ms), and the then wave filter of three kinds of colors of gating calculates interior TCS230 during this period of timeOutput umber of pulse, calculate a scale factor, these umber of pulses can be become to 255 by this scale factor. In realityWhen border is tested, use the same time to count, the umber of pulse recording is multiplied by the scale factor of trying to achieve again, then just canObtain the value of corresponding R, G and B. After blank level adjustment, just can carry out rgb value test to sample.
Preferably, described host computer 3 data processors are PIC16F877 single-chip microcomputer.
PIC16F887 (PeripheralInterfaceController) is by Microchip company production developmentPICmicro series single chip microcomputer, has FlashProgram program internal memory function, can repeat burning program. There is costLow, use the features such as simple, stable performance, therefore, native system adopts PIC16F877 single-chip microcomputer.
TCS230 color sensor is transferred to PIC16F877 single-chip microcomputer by the sample rgb value obtaining and processes, simultaneouslyPIC16F877 single-chip microcomputer also completes the selection control to TCS230 color sensor wave filter. Under the irradiation of ambient light, colorThe power of sensor senses ambient light, is sent to pulse signal by OUT output pin the RC0 mouth of PIC single-chip microcomputer, completesThe collection of signal and transmission. By reading the value of T1 of PIC16F877, calculate respectively 3 kinds of output frequencies of TCS230,Then determine the value of RGB.
Preferably, described display 5 is LCD1602 liquid crystal display.
System requirements output display measurement result, require liquid crystal can show letter and number, consider from low price and small size,Native system selects LCD1602 (LiquidCrystalDisplay) liquid crystal display to show, it is industrial character mode lcd,Can show that 16 × 02 is 32 characters simultaneously. LCD is compared with LED charactron, and power consumption reduces greatly, is convenient to portableDesign. The FPDP of LCD1602 is connected with the I/O port of PIC16F877 with read-write control port, when LCD Enable Pin placeIn the time of high level, enter read-write sequence toward single-chip processor i/o port write, can control LCD and show. Therefore, as preferred sideFormula, display is LCD1602 liquid crystal display.
