A monitoring system for vibration signal acquisition has been designed in this paper; and its design core of the system is supposed to be the STM32F106RBT6 single-chip microcomputer. And the power supply circuit of the sensor, signal conditioning circuit, AD converter module and communication module are analyzed. Analog data acquisition of high precision can be fulfilled through the design of Fourier transform by means of MATLAB as well as the actual measurement analysis of certain analog signal. As for its advantages in the following aspects, like powerful functions, low costs, high precision, small volume and etc, this system can be applied to the acquisition of vibration signal.
