[technical field]
The utility model relates to the food safety detection technical field, relates in particular to a kind of agricultural product security check and analysis instrument.
[background technology]
Bright is the sky with the food, and agricultural byproducts are food indispensable in the lives of the people, and its quality and safety are directly connected to the healthy of the people.Traditional agricultural product detect the detection mode of mainly taking laboratory off-line sampling, such detection mode accuracy height, but efficient is low, can't adapt to large batch of detection requirement.Along with the development of agribusiness and enriching of agricultural product kind, the project that agricultural product detect is more and more, and ageing requirement is also more and more higher, and on-the-spot and online detection is arisen at the historic moment and come into one's own day by day.
[utility model content]
Based on this, be necessary to provide a kind of agricultural product security check and analysis instrument that can realize on-the-spot online detection.
A kind of agricultural product security check and analysis instrument, comprise light source, the measurement annex of the collected specimens spectrum that links to each other with light source, with measure annex and link to each other and sample spectra is carried out light-splitting processing obtain all solid state beam split light path of near infrared spectrum, link to each other with all solid state beam split light path that processing obtains the driving circuit of spectroscopic data and the transmission interface circuit that spectroscopic data is transferred to upper computer software near infrared spectrum.
Preferably, described light source is the halogen tungsten lamp light source.
Preferably, described measurement annex comprises that solid sample is measured annex and liquid sample is measured annex, and described solid sample is measured annex and adopted diffuse reflection optical fiber probe, and described liquid sample is measured annex and adopted the projection sample cell or reflect the pipeline probe thoroughly.
Preferably, described all solid state beam split light path comprises slit, grating, curved reflector.
Preferably, described driving circuit is an InGaAs diode array detector driving circuit.
Further preferred, described driving circuit comprises the quick sweep circuit of temperature-control circuit, cooling circuit and detector array.
Preferably, described transmission interface circuit comprises USB high-speed transfer interface and WiFi wireless transmission interface.
Above-mentioned agricultural product security check and analysis instrument, carry out light-splitting processing by spectrum and obtain near infrared spectrum sampling, because it is responsive especially that near infrared spectrum contains hydrogen group to the C-H in the organism, O-H, N-H etc., therefore near infrared spectrum has reacted the component concentration of organism sample, and analysis speed is fast, can realize the on-the-spot and online detection of agricultural product.And near-infrared spectrum technique can not destroy sample, does not pollute the environment, and is simple to operate.
[description of drawings]
Fig. 1 is the structural representation of agricultural product security check and analysis instrument among the embodiment.
[embodiment]
As shown in Figure 1, a kind of agricultural product security check and analysis instrument, comprise light source 1, the measurement annex 2 that links to each other and be used for collected specimens spectrum with light source 1, and measure annex 2 and link to each other and be used for that sample spectra is carried out light-splitting processing and obtain all solid state beam split light path 3 of near infrared spectrum, link to each other with all solid state beam split light path 3 that processing obtains the driving circuit 4 of spectroscopic data and the transmission interface circuit 5 that spectroscopic data is transferred to upper computer software near infrared spectrum.
In one embodiment, light source 1 can adopt the halogen tungsten lamp light source, and it adopts voltage stabilizing stream Driving technique, thereby can guarantee stabilized intensity.Measure annex 2 and comprise that solid sample is measured annex and liquid sample is measured two kinds of measurements of annex annex, wherein, solid sample is measured annex can adopt diffuse reflection optical fiber probe, and liquid sample is measured annex and adopted projection sample cell or saturating mirror based fiber optica probe, is used for collected specimens spectrum.The sample spectra of 3 pairs of collections of all solid state beam split light path is carried out light-splitting processing, can access near infrared spectrum.All solid state beam split light path 3 comprises parts such as slit, grating, curved reflector, adopts computed in software light channel structure and verification parasitic light, can access the parameter of optimum light path layout and each parts.In one embodiment, driving circuit 4 is an InGaAs diode array detector driving circuit, comprise the quick sweep circuit of temperature-control circuit, cooling circuit and detector array, wherein cooling circuit adopts the TE cooling circuit, be used from the minimizing thermonoise with temperature-control circuit one, the quick sweep circuit of detector array adopts the quick sweep circuit of detector array of CPLD (Complex Programmable Logic Device, CPLD).Transmission interface circuit 5 can adopt USB (Universal Serial Bus, USB (universal serial bus)) high-speed transfer interface and WiFi wireless transmission interface.
In one embodiment, spectroscopic data is transferred to upper computer software and handles, upper computer software mainly comprises spectra collection and Chemical Measurement two parts, wherein spectra collection partly is used for receiving near infrared spectrum data, and Chemical Measurement partly has functions such as spectrum pre-service, wavelength screening, polynary quantitative correction, pattern-recognition be qualitative.With dairy products is example, by to dairy products (as milk powder, liquid milk etc.) its near infrared spectrum of sample measurement, and obtain the properties of samples reference value (as protein, lactose, fat etc.), obtain dairy products magnanimity component quantifying analytical model by spectrum Preprocessing Algorithm and polynary quantitative correction algorithm, by the sample sets of mingling to artificial manufacturing, measure its near infrared spectrum and mingle the degree reference value, carry out the qualitative algorithm of spectrum pre-service and pattern-recognition then, obtain dairy products trace adulteration qualitative analysis module, can obtain dairy products near-infrared analysis model database by these two analytical models, by this model database with a certain amount of for mingling boundary, can make the very high judgement of accuracy to whether mingling in the dairy products.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
