基于ARM的嵌入式ACFM检测系统设计

Design of ACFM Test System Based on ARM Technology

针对传统ACFM检测系统的稳定性和实时性差的问题,提出一种基于S3C2440和嵌入式Linux操作系统的ACFM裂纹信号采集分析系统的设计方案。重点阐述了系统硬件结构中的信号处理模块和数据采集模块的设计,并对软件设计进行讨论。经实验验证表明:该系统能够满足实时性要求,稳定性良好,可靠性较高。

According to the poor stability and real-time performance of traditional ACFM test system, a new vibration signal acquisition and analysis system method based on S3C2440 and embedded Linux operation system is proposed. This paper specially focuses on the design of the signal pretreatment module and data acquisition module of hardware. Moreover, 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.
