摘　　要：结合漏磁检测、信号处理和单片机技术 ,研制一种低功耗的便携式漏磁检测装置。详细介绍系统各部分的功能。测试表明 ,此装置通过沿管道轴向一次扫查可以全面、快速地检测出管道内外壁缺陷。A portable, lower power magnetic flux leakage (MFL) testing system combining MFL method, signal processing technique and single chip microprocessor (SCM) technique was developed. Experimental data showed that the system could detect the inside and outside defects of a pipeline quickly and reliably in one process of scanning. The system can be widely used in defect detection of industrial pipelines.
