Description
Technical field
The utility model relates to the device of fruit quality Non-Destructive Testing, relates in particular to portable fruit pol the cannot-harm-detection device that a kind of band is weighed.
Background technology
Along with the continuous increase of fruits output and improving constantly of people's living standard, the consumer more and more values for inside quality such as mouthfeel, pol, acidity etc. when choosing fruit, and the pol of fruit is to estimate an important indicator of fruit maturity, fruit quality.And at present to the check of fruit internal quality often based on destructive chemical analysis, as pol anthrone colourimetry or saccharometer, acidity is measured with potential method (pH meter), vitamin content is with colourimetry and high chromatographic determination mutually etc., and these methods exist all that sample preparation is loaded down with trivial details, analysis time long, detect problems such as cost height and accuracy of detection are low.Therefore study portable quick nondestructive detect the fruit internal quality device be realize fruit produce in the scientific management (scientific basis as fruit picking time is the requirement whether fruit arrives the minimum sugar content of high-quality fruit) and the important process of fixing the price according to the quality postpartum and selling.That is that all right is ripe, improve and the less present situation of commercial applications based on the portable the cannot-harm-detection device of present fruit internal quality, the utility model provides a kind of intersection based on multinomial technology such as spectral analysis technique, optical fiber sensing technology, stoichiometry learn a skill, most important index pol is developed a kind of portable fruit pol the cannot-harm-detection device with function of weighing as detecting evaluation index in the selection fruit internal quality.
Carried out at present abroad some fundamental researchs on the portable set of fruit internal quality Non-Destructive Testing, developed portable saccharometer based on visible near-infrared line as Japan, pol sensing range 5-30Brix% (pol), detection speed are 3 seconds.In addition, countries such as Germany, Israel and New Zealand have also successively carried out near-infrared spectrum analysis at aspects such as the pol of fruit, defective, degree of ripeness and have studied and developed corresponding portable checkout equipment, but drop into the few of production application, reason mainly be portable detection signal too a little less than, the not high and bad adaptability of the precision of detection.
In Jap.P. NO.09-089767, the mancarried device that utilizes the near infrared detection apple sugar content is described, this method and apparatus is that the fruit reflected light is divided into different wave length after beam splitting system (in the about spectroscope of concave diffraction grating is arranged) light is incided on the photoelectric conversion unit, by calculating absorbance, second differential processing, and set up forecast model with the spectral value at 912nm and 888nm place, think that can be used for the scene that the orchard tree goes up fruit quality detects.But in this structure, the beam split precision is subjected to extraneous factor influences such as (vibration, temperature) easily, thereby accuracy of detection is not high.
The patent NO.02808798.4 that people such as preceding Tian Hong apply for has at home described a kind of hand-held pick-up unit of using as the internal soundness of inspection object of checking by spectral analysis non-destructive ground.Different with above-mentioned technology is that the small-sized spectroscope that is combined into compactly with linear pattern continuous variable interference filter and linear pattern silicon array sensor in this technology has replaced diffraction grating, so more compact structure.Yet in this hand-held pol pick-up unit, the same with above-mentioned patent, adopt the catoptrical mode of detection fruit to detect fruit pol content, this mode can only detect thin skin fruit, owing to the degree of depth that light enters fruit internal is limited, can not correctly reflect fruit internal quality for pachydermia fruit.
Among the patent NO.200510056732.3, a kind of portable nondistructive detector for fruit inner quality has been described at home.In this technology, shine measured object (fruit), and detect, detect the near infrared light of transmission from fruit, and realize fruit quality (water core degree) is detected classification by setting up forecast model with the photoelectric detector that is located at top and bottom with a circle led light source.In this portable nondistructive detector for fruit inner quality, sample window has adopted closed, thereby is subjected to the influence of environment temperature when detecting easily.Though in design, be provided with a temperature sensor near described photoelectric detector and limit, lamp source, in detection model, considered Temperature Compensation, but still there is the low problem of accuracy of detection that causes thus, and improved the cost that installs, in addition because also there is the problem to the influence of fruit quality in the heat radiation difficulty.
In addition, fruit weight is the foundation of fruit metering, and also nobody proposes a kind of portable detector that can realize simultaneously that fruit weight and inside quality pol detect at present.
Summary of the invention
Portable fruit pol the cannot-harm-detection device that the utility model provides a kind of band to weigh, thus satisfy the needs that merchandise sales are fixed the price according to the quality and measure simultaneously.
The technical solution adopted in the utility model is as follows:
Be provided with display, keyboard at main body cabinet one balustrade deching, be provided with printer in the main body cabinet, microprocessor, spectrometer, by the weighing system that amplifier, A/D converter and LOAD CELLS are formed, display, keyboard, printer, spectrometer and converter are connected with microprocessor respectively; The scale pan that is connected with LOAD CELLS is housed on the main body cabinet, the carrier of tested fruit is housed on the scale pan, the fruit carrier has two oblique through holes to the center of circle, two through hole is at 45～and 90 °, the oblique through hole that detection head is put into the fruit carrier is connected with spectrometer, be equipped with on the light source shelf in another outside of main body cabinet can from directly over or side-irradiation to the near-infrared light source of fruit, perhaps near-infrared light source is installed in the main body cabinet, shines fruit by the luminous source optical fiber in another the oblique through hole that is installed in the fruit carrier.
Be equipped with on the described light source shelf can from directly over or side-irradiation to the near-infrared light source of tested fruit, be on the flange in another outside of main body cabinet, the montant that can slide up and down on flange to be housed, lever arm is equipped with in the montant end, one end and the lever arm of stiffener are hinged, the other end of stiffener and montant straight trough are hinged, and near-infrared light source is housed on the lever arm.
