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 order to interpret the detection signal better, AC1856 high-speed parallel acquisition card is adopted to detect the excitation signal and the output signal at the same time. The hardware block diagram and software composition of the whole detection system are given. Practice has proved that this Law practical and feasible.
