Embedded bearing fault detection system based on DSP and ARM

The utility model relates to an embedded bearing fault detection system based on a DSP and an ARM. The embedded bearing fault detection system comprises a signal acquisition module, a DSP signal processing module and an ARM control module. The embedded bearing fault detection system establishes a complete embedded system hardware platform based on the DSP and the ARM, and realizes data exchange between the DSP and the ARM through a double-port RAM. The DSP serves as a data operation part, and gives full play to its unique advantage of digital signal processing. The ARM is responsible for control, data display and storage. The DSP/ARM-based dual-core structure has great advantages in performance and price, and is portable. The core algorithm of the embedded bearing fault detection system adopts the resonance demodulation method, and obtains characteristic signals of bearing faults through carrying out digital filtering, Hilbert conversion and FFT on the digital signals.
