A fragment counting and control system, consisting of mechanical and electronic components such as a fragment counting execution mechanism, a sensor platform, various sensors, a signal counting and processing instrument, a timer, a motor driver and the like. A fragment falls onto the sensor platform from the outlet of the fragment counting execution mechanism, such that the sensor on the sensor platform generates a signal; the signal is transmitted to the signal counting and processing instrument; the signal counting and processing instrument processes the signal and compares the processed signal with a preset value; the processing instrument transmits a control signal to the timer and the motor driver according to the ratio; the timer controls the motor driver to start and stop; the motor driver processes the processing instrument signal, and transmits a driver signal to the motor; and the motor changes rotation according to the driver signal so as to drive a vertical shaft to change rotation, thus controlling the frequency of falling fragments. |
