Description
Technical field
The present invention relates to a kind of sensing detection device of medical instruments field, especially a kind of digital photoelectric biology sensor.
Background technology
When current photoelectricity biological sensing probes is combined with reagent test sheet and detects, color sensor normally covers red, green, basket optical filter through revising on independently photodiode, then output signal is processed accordingly, color signal could be identified; What have gathers both, but the simulating signal exported, need an A/D circuit to sample, to the further quantification treatment of this signal, just can identify, add the complicacy of circuit, and there is larger conversion and identification error, have impact on the effect of identification.On signal optical source, conventional light source uses thermal light source, and damping capacity is large, poor stability, will to light source calibration, to user bring great inconvenience before needing each use in actual use procedure.The inconvenience caused for above-mentioned reasons and latent instability hidden danger, therefore, be necessary to provide a kind of precision high, digitizing, possess excellent sensitivity and atopic, structure is simple, be convenient to produce, the digital photoelectric biological sensing probes be user-friendly to.
Summary of the invention
In view of the problem existing for existing biology sensor, the invention provides a kind of precision high, digitizing, possess excellent sensitivity and atopic, structure is simple, be convenient to produce, the digital photoelectric biology sensor be user-friendly to.
The present invention comprises the color sensor on biology sensor reagent test sheet, circuit board, circuit board.
Principle of the present invention is: be provided with the color sensor and the LED of device in mechanical session transmitter fixed on circuit boards, when detecting, by adding electroluminescence to LED, light focuses the light into test pieces through session transmission, color distortion is there is in test pieces owing to reacting with chemical substance (or enzyme), when focused light is irradiated on detection lug, different because of the color amount of refraction that produces of difference, light after refraction transfers to color sensor through session, color sensor is converted to the frequency values of total digitalization after receiving Different lightwave, according to frequency values variable quantity just distinguishable go out variable concentrations test sample book and test pieces reaction result, by the microprocessor processes frequency variation signal on circuit board, just quantitative or semiquantitative mode the concentration results of test sample book can be calculated after analytic signal.The sample having color to change after the present invention's total digitalization photoelectricity bio-sensing pick-up unit can realize reacting to various chemical reagent, biology enzyme detects fast, has the features such as simple and efficient, measuring accuracy is high, good stability.
The present invention is achieved in that digital photoelectric biology sensor, comprises test pieces, microprocessor-based boards, circuit board is provided with sensor, it is characterized in that, described sensor is color sensor; Described circuit board is also provided with LED and transmission session, transmission session is certain tilt angle alpha relative to circuit board.
Described LED and transmission session match each other, and quantity can be one or two.
Color sensor on this pick-up unit circuit board is embedded in the color sensor position on detection head, LED is arranged in LED hole, work is powered up to LED and color sensor by Single-chip Controlling, LED light is allowed to focus in test pieces through optical path, refract light in test pieces after testing head optic path to color sensor receive window, color sensor receives light signal after digital quantization, the color variable quantity on detection lug just can be demonstrated by single-chip microcomputer analyzing and processing, on detection lug, color variable quantity changes with test sample book concentration, the concentration value of test sample book can be drawn thus.
Digital photoelectric biological sensing probes is that a kind of color sensor of programmable digital compatibility interface and optical path detection head of utilizing combines the equipment analyzed reagent test sheet color characteristics.Because totally digitilized photoelectricity biological sensing probes color sensor and test pieces are as detecting element, by the conversion of color of light to frequency, the color sensor of programmable digital compatibility is integrated in configurable silicon photoelectric diode and current frequency converter on a single cmos circuit, on one chip, be also integrated with RGB (RGB) three kinds of light filters simultaneously, it is the RGB color sensor having digital compatibility interface, the signal exported is digital quantity, can Direct driver standard TTL or CMOS logic input, therefore can directly be connected with microprocessor or other logical circuit.Due to output is digital quantity, and can realize the conversion accuracy of each color channel more than 10, thus no longer needs A/D change-over circuit, and make circuit become simpler, precision is high, possesses excellent sensitivity and atopic.Therefore, the combination of color sensor and test pieces can be widely used in various field, the process measurement of such as medical treatment/medicine (clinical-chemical analysis and disposal), biological industry, environment measurement, food security, the stability assessment of chemicals, colorimeter measure application, colour print, the calibration of computer color monitor and paint, textile, cosmetics and printing material and digital imagery etc., and its range of application constantly expands.Particularly, in medical diagnosis and food manufacture field, totally digitilized photoelectricity biological sensing probes is widely used for analyzing the biological sample comprising blood, urine, food additives.
The advantage of digital photoelectric biological sensing probes is that volume is little, adopt the optical signal transmission detection head designed through great many of experiments, what export is digital information, control circuit is simple, LED is cold light source, stable performance, and its miniaturization easily realizes, measuring-signal Absorbable organic halogens obtains, and easily realizes the combination with various electronic equipment.
This pick-up unit key point is the unique design of optical path, and control angle α is with regard to the size of adjustable focus point and distance.This pick-up unit design angle is controlled by 10 ° ~ 60 ° scope interior focusing roads, thus realizes the different design needs required, meets different using state.
To sum up telling, the present invention has following advantage:
Structure is simple, and die sinking injection mo(u)lding is easy, and Angle ambiguity is simple, is easy to miniaturization;
Focus on, light intensity is large, and refracted signal is strong;
Signal stabilization, total digitalization, possesses excellent sensitivity and atopic, by force anti-interference;
The combination of as easy as rolling off a log realization and various electronic equipment, that there is biology sensor to retrochromism identification and pick-up unit thereof, can be used for shades of colour discriminance analysis device, as various electronic equipments such as photoelectricity blood glucose meter, edible oil analyser, Urine Analyzer, blood analysers.
