Abstract
Aiming at the demand of real-time monitoring of gate vibration problems of hydropower
stations, the steel gate vibration monitoring system was designed and implemented. The system
collects the vibration signal through the acceleration sensor, and adjusts and amplifies the weak signal.
The STM32F103ZET6 is used as the control processing core, which controls the A/D conversion and
transmits the data to the memory through DMA, and then transmits the data to the computer through
the serial port communication. The design of the ADXL356 accelerometer and the design of the signal
conditioning amplifier circuit and the software design of the acquisition system are highlighted. The
analysis of the experimental results shows that the system can achieve high-precision acquisition of
signals, which can provide technical reference for the online monitoring system of gates.
