Design of Low-frequency Vibration Detection System

In order to improve the accuracy, feasibility and convenience of the vibration detection system, design a sim- ple and practical low-frequency vibration detection system. This system is designed based on STM32 platform, composed of shaping circuit, the measurement of vibration signal, wireless transmission and TFT touch screen display module, μC/OS-II embedded system transplantation, miniGUI interface design, and finally realize the display of waveform and frequency of vibration signal. By testing this system, find that it is stable, reliable and real-time, basically reached the ex- pected requirements and can be very good to meet the actual demand, which has a widespread application prospect.
