Flower color classifying of plants is effectively achieved in experiments, and continuous measuring experiments are done on leaves of living plants. The portable flower color classifying and growth state detecting device not only can be used to classify coloring matters of leaves and petals of plants and follow up to measure growth states of plants, but also can be used to analyze components of coloring matters of ancient art work, and has very important significance in researching the manufacturing technique and components of pigments of ancient art work and achieving the recovery and converse of ancient art work.

Description

Classification of portable plant pattern and growth conditions pick-up unit

Technical field

The utility model belongs to a kind of check and analysis technology, specifically is a kind of plant flowers colour sorting and growth conditions optical detection analytical equipment.

Background technology

The color of flower mainly is by the decision of the pigment in the petal, the most important thing is anthocyanidin, flavonoids and carotenoid, by reflecting the light of different light waves, makes petal present different colors.How much relevant deep or light the and anthocyanidin of pattern and content of carotenoid be, and how much relevant with environmental baseline anthocyanidin and content of carotenoid be, as pH value, temperature, illumination, seasonal variations etc.Therefore study plant petals pigment and monitoring plant growth conditions developing technology, the conversion of ornamental plant flower color gene and the research of extraction plant pigment are had important directive significance.

Usually, the pattern of plant classification is that method by range estimation, high performance liquid chromatography or absorbance measuring realizes.Yet, realize that real-time, Fast Classification is measured and there is certain deficiency in the continuous monitoring of growth conditions.

Mainly show the following aspects:

1) Mu Ce method can be carried out the simple classification of plant pattern, to the notion of the qualitative of pattern pigment and the quantitative test amount of not having, does not more have the accurate change information can be for reference to the monitoring of plant growth state.

2) high performance liquid chromatography and absorbance measuring can both provide accurate plant pattern pigment information, but its routine analyzer complexity, consuming time, instrument costs an arm and a leg.Generally all need collected specimens, measure through carrying out lab analysis after the specimen preparation processing, can not carry out real-time analysis to continuous monitoring vegetation growth state and plant pattern with environment and climate change, owing to need sample collecting, therefore all can not effectively carry out to tracking measurement plant leaf blade and petal.

The utility model is at live plant petal and blade, utilizes optical detective technology to realize the reflective spectral measure of plant petals and blade, handles the Continuous Tracking that realizes plant flowers colour sorting and growth conditions by spectral analysis.

The utility model content

The utility model costs an arm and a leg at the traditional analysis instrument, analyze consuming time, complicated, and can not provide real-time, continuous monitoring information, utility model a kind of can be used in real time, continuously, classification of portable plant pattern and growth conditions pick-up unit that cheap on-line tracing is measured, the pigment classification and the plant growth state tracking measurement that not only can be used for plant petals and blade, and can be used for the analysis of ancient artifacts colour component, to the manufacture craft of research ancient artifacts, pigment composition and realize incunabular reparation and preserve significant.In addition, under the condition of changing excitation source, can also be used for the qualitative and quantitative test of plant petals, blade and ancient artwork pigment composition, research plant petals, the variation of blade constituent content and tracking measurement plant growth state are had significant application value.

The technical solution of the utility model is as follows:

Classification of portable plant pattern and growth conditions pick-up unit, it is characterized in that including: light source, the light source light-emitting window is through the coupling mirror group launching fiber that has been of coupled connections, receiving optical fiber is linked on the spectrometer, terminate on the same optic fibre end before reception optical fiber and the launching fiber, the optic fibre end front end is placed plant petals or the blade that needs detection, and the signal output of spectrometer inserts data Collection ﹠ Processing System.

The utility model is made up of optical emitting assembly, optics receiving unit and probe assembly etc.The continuous light that lamp source is sent is coupled to launching fiber through the coupling mirror group, act on plant petals or blade, the reflectance spectrum that produces carries out beam split by receiving Optical Fiber Transmission to spectrometer, and carry out the conversion of photosignal by detector, enter data Collection ﹠ Processing System then and carry out data acquisition process, power supply provides the power supply of light source, detector and data Collection ﹠ Processing System and logical sequence and the trigger pip of surveying control.

The utility model is applicable to the qualitative and quantitative analysis of plant petals pigment, pigment in plant leaf and ancient artifacts paint pigment category measurement and pigment composition, and can be used for plant growth state in real time, the Continuous Tracking monitoring.

Principal feature of the present utility model is summarized as follows:

1) system adopts micro spectrometer and continuous lamp source as transmitting illuminant (also can utilize natural light) and spectrum detection device, is guiding device with optical fiber, and with portable computer as signal controlling, data acquisition and analyze display terminal; Its compact conformation, volume is little, in light weight, is easy to carry to be used for the field work measurement;

2) analyzed sample need not to gather, and directly (plant petals, blade etc.) carry out Measurement and analysis on live plant, have reduced sample collecting, preparation and pretreatment process, have avoided the secondary pollution problems of sample, and can provide analysis result in real time;

3) system can adopt lamp (sunshine) as transmitting illuminant, therefore can make system compact more, increases the reliability and the stability of system; Under the situation of changing light source, can be used for the fluorescence spectrum feature measurement or the analysis and research of contained pigment composition of plant petals, blade etc.;

The classification of portable plant pattern is to utilize continuous lamp source as transmitting illuminant with the growth conditions detector, reflectance spectrum by receiving plant petals or plant leaf blade is as analytic target, avoided traditional manual sampling, pigment composition information by suitable data processing algorithm analysis plant realizes the classification of plant pattern with this.Pigment according to continuous monitoring is formed and change information, realizes the monitoring to plant growth state.

The effect of utility model

System carries out the reception transmission of light emitted and plant petals or blade reflectance spectrum with optical fiber, avoided the influence of external environment effectively to the measure spectrum signal, adopt micro spectrometer and continuous lamp source as transmitting illuminant (also can utilize natural light) and spectrum detection device, and with portable computer as signal controlling, data acquisition and analysis display terminal, reduced system bulk greatly, make the system architecture compactness, be easy to carry, be applicable to the plant petals pigment, the qualitative and quantitative analysis of pigment in plant leaf and ancient artifacts paint pigment category measurement and pigment composition, and it is real-time to can be used for plant growth state, the Continuous Tracking monitoring.
