| 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 PCl2010 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. |
