Abstract:

Aiming at the disadvantage of detecting precision is not high, poor real-time performance and high price for rotating machinery vibration system, a design scheme of embedded vibration detecting system with high accuracy is proposed. System uses S3C6410 embedded chip and high precision A/D converter AD7705 for data acquisition, program development is in the embedded platform of Windows CE 6,analyzed data with combining multiple dimensionless parameter and frequency domain technique to, and realize rotating machinery vibration detecting. Experiments show that vibration detection is fast, accurate, and the system has good ability for fault diagnosis and better application prospect.
