Portion's light source transmitting detection light beam, detection light beam is by detecting that window flange (44) is irradiated to the surface of harvest cereal to be measured, reflected light
Beam will carry the spectroscopic data for harvesting grain quality information by the collection of spectrometer (43) interior detectors, and spectroscopic data passes through communication
Transmission line (46) is transferred to the spectrometer control unit (52) of control system (5)；
3) spectrometer control unit (52) first obtains absorbance of the harvest cereal near infrared spectrum region, according to absorbance
The quality information of harvest cereal is calculated, and is transferred to display (53)；
4) above-mentioned steps are first with the cereal repeat step 1 of known quality information)~processing 3) is modeled, obtain close to actual receipts
The forecast model of grain quality information to be harvested under the conditions of obtaining, carries out detection to the cereal of unknown qualities information with forecast model and obtains
Obtain quality information.
