The invention discloses an intelligent identification device of yellow rice wine age based on near-infrared spectra, which is characterized by the following: placing the photoelectric sensor and detecting platform with detecting clamp in the incubator; setting the light source and filter piece of near-infrared luminescent diode on the left side of detecting clamp at the neck position; placing the optical lens at the right side of detecting clamp; opposing the exit face of optical lens to the receiving face of optical fiber; connecting the exit end of optical fiber with the input end of photoelectric senor; setting the exit face of filter piece to oppose the receiving face of optical lens at the same axle through the detecting clamp; loading the temperature sensor and workpiece detector on the side of detecting clamp from the bottom of optical lens sequently. The invention solves the problem of inaccurate wine age identification result when the light splitter rotates in different temperature conditions. |
