针对钢铁电磁无损检测中某些特殊的钢铁材质检测结果不理想的情况,根据初始磁导率原理,提出了DSP技术应用于电磁无损检测试验装置的设计方案。试验结果表明,采用DSP检测方法初步收到了较好的效果。
According to the principle of initial permeability, the design scheme that DSP technology is applied to the electromagnetic nondestructive testing device is put forward in the case of some special steel materials testing result is not ideal. The test results show that, using DSP detection method initially received good results.
