Design of Realtime Condition Monitoring System of Motor Based on STM32
Aiming at the problem that the motor can not accurately locate the fault,this paper designs a motor condition monitoring system based on STM32F407.Firstly,the system uses acceleration sensor ADXL345 and temperature sensor DS18B20 to collect vibration and temperature signals.Secondly,the preprocessed data is obtained by fast Fourier transform in the frequency domain.Finally,all the data is transmitted to the screen through the serial port for display.The experimen-tal results show that the system has good practicability.It can not only collect the running state of the motor in real time,but also display the data in an intuitive form,so that the staff can see it at any time.
