摘要
分析了电涡流检测的特点,为了更好地判读检测信号,采用了AC1856高速并行采集卡,实现激励信号与输出信号的同时检测,给出了整个检测系统的硬件框图及软件组成,实践证明此法实用可行.
In this paper the characteristics of eddy current testing are discussed. In order to indentify the detection signal more effectively, AC1856, the new data acquisition card with high speed and parallel sampling function is used. So the exciting signal and the output signal can be detected at the same time. Moreover, the hardware and software structures of the whole testing system are presented. The practice proves that this method is viable.
