In view of the large cream-colored chosen test design and manufacture of large cream-colored separator
Was selected from the top of the hopper into the machine, through the vibration of the vibrator unit, selected material falling along the channel, accelerate whereabouts into separation indoor observation area, and through the between the sensor and the background plate. Under the action of light source, according to the strength of the light and color change, make the system to produce the output signal to drive the solenoid valve work out different color particles blow to meet hopper waste cavity, and good selected finished materials continue to fall to meet hopper cavity, so as to choose other purposes. With 2048 high performance CCD image sensor, choose color resolution was 0.02, South Korea's big manufacturer of cream-colored separator can clear awareness material local small colour difference;
For design and manufacture of high quality large cream-colored choose detection, special industrial camera, its working parameters according to color requirements, all kinds of raw materials and optimize the optical path design, make sure every single material can perfectly imaging in image sensor; Using high-speed DSP digital image processing technology, testing is faster and has higher recognition rate; According to the spectral characteristics and identification of characteristics of rice, starting from the spectral analysis to design sensitivity and robustness of grains detection algorithm for special purpose, meet the slight color difference detection at the same time to improve the robustness, other factors in order to avoid material surface interference; Main control system adopts the ARM9 series of high-end embedded processor chips, effectively improve the control speed and color selection accuracy; The whole machine adopts the intelligent closed-loop control, industrial data bus ensure the reliability of communication and control system, strong anti-interference ability; Interface using industrial-grade 7 inch TFT color touch screen, set parameters is simple and easy to operate, more pleasing color interface; Using professional high-speed valve action and high response frequency, low power consumption, long service life; Double detection at the same time, and have a variety of work mode, to adapt to a variety of meters of material requirement, has a strong universality; High precision, to carry out than low; Using intelligent temperature and pressure control technology to guarantee the machine always run in the best working state; Automatic fault alarm, modular structure is easy to repair.
