摘要：

在Windows XP系统平台下，采用PCI2010数据采集卡设计了多通道涡流探伤仪。通过正交分解法得出涡流信号的相角和幅值，并给出了PCI2010与涡流探伤电路进行对接的技术方案。实验结果表明，该探伤仪探测钢管速度最高能达到100 m/min，误报率控制在1%以下，基本不漏报，高于国家标准。

Abstract:

We devise a multi-channel eddy current instrument with a PCI2010 data acquisition card in the platform of Windows XP. We employ orthogonal decomposition to obtain phase angle and amplitude of an eddy current signal, and then present a technical proposal that PCI2010 card connects with eddy current testing circuit. Experimental results show that the instrument can detect the velocity up to 100 m/min for steel tubes. Its false alarm rate is less than 1% and its alarm failure rate is almost zero, higher than those in national standards.

Key words: Windows XP platform, PCI2010, orthogonal decomposition, eddy current instrument
