In order to quickly collect the vibration parameter of the material vibrator in the color sorter, obtain the vibration state of the vibrator simply and intuitively and improve the performance of the vibrator effectively. An FPGA-based vibration detection system for the vibrator of the color sorter was designed. The system was mainly composed of vibration acceleration sensor, FPGA processing board and host computer display device. The system could display the vibration waveform of the vibrator during operation and provide relevant reference information through the vibration data acquisition of the sensor, the data processing and communication of the FPGA processing board, and the data receiving of the host computer. The system could obtain the vibration acceleration waveform of the vibrator during operation and gave the maximum vibration acceleration through the timing simulation during sampling and communication and experimental testing of vibration detection platform. Corresponding conversion could be used as a reference for vibrator improvement. Therefore, the system has high application value.
