基于ARM-WindowsCE的便携式漏磁检测仪设计

摘要

In order to analyze the relationship between the magnetic flux leakage signals and the types of defect, a portable magnetic flux leakage testing instrument was designed. This paper presents the structure of this magnetic flux leakage testing instrument based on ARM9 embedded configuration. With the S3C2440A processor as the core and WindowCE5. 0 as the operating system and by using HONEYWELL company's magnetism sensor HMC1021 to obtain magnetic flux leakage signals on the surface of ferromagnetic material,the instrument can fulfill the basic function of the magnetic flux leakage testing instrument in a better way.%为了分析漏磁信号和缺陷类型之间存在的对应关系,研制了一种适合现场检测的便携式漏磁检测仪.给出基于ARM9嵌入式结构的漏磁检测仪总体结构,该检测仪以S3C2440A处理器为核心,采用WindowsCE5.0为操作系统,以HONEYWELL公司的HMC1021磁阻传感器来获取铁磁材料表面的漏磁信号,较好地实现了漏磁检测仪的基本功能.
