| Abstract: | According to the poor stability and real-time performance of data acquisition and analysis system based on traditional MCS-51 single-chip microcomputer, a new vibration signal acquisition and analysis system method based on S3C2440A and embedded Linux operation system is proposed. This paper specially focuses on the design of ARM master module, the signal pretreatment module and data acquisition module of hardware. At last the software design is discussed. The experimental results prove that the system can meet the need of real-time performance, and its stability and reliability are good. |
