Rice, the original temperature will affect the accuracy of the big cream-colored separator
Big cream-colored separator for random pulse signal detection signal. When the value of the pulse signal is greater than a certain threshold, the corresponding 1/0 mouth need to output a certain delay and the width of the digital drive signal of pulse signal as spray valve. Therefore, the timing of the output pulse and the pulse width control problems. By software implementation of the output pulse timing control, usually adopt the method of each channel entirely separate independent processing. It need to record every useful signals of each channel and timing, the need for each outlet state judgment and processing. When the actual application of the software design is complex, the program code is long. Time control precision and poor real-time performance of the system. Especially when the number of channel system is large, may become impossible to application. This paper puts forward a kind of software is used to implement multi-channel random signal system requires the combination of the output pulse time control algorithm. Assume that the input analog signal for single pulse signals, when the value of the pulse signal is greater than the threshold (referred to as the useful signal). Need to output a corresponding high level pulse.
Color vision of the raw materials of rice grain content. A vision of the general requirements raw rice grain content is less than color color machine calibration range, choose the color accuracy, to carry out than and yield can be up to standard. When different color particle content beyond the normal range, to ensure accuracy of a certain color to choose and carry out than, you must reduce production, makes the unit manufacturing cost greatly increase; On the other hand, to meet the production requirements, the color choice inevitably reduce accuracy, out of the higher than necessary, thus affecting the quality of product and milled rice rate. The temperature of the material of rice. After dealing with the white more machine grinding and polishing of rice, because its temperature is higher than normal temperature, such as immediately into the color machine, easy to make rice chaff powder on the surface of the adhesive surface of the channel, affects the normal flow of rice grains, reduce the effect of color to choose.
