涡流探伤中数据的实时采集和实时处理

Data Real time Acquisition and Real time Process in the Eddy Current Test

在充分利用采集卡内部缓存的基础上 ,利用定时器控件进行数据的实时采集显示 ,实时参数计算和在线存盘 ,从而避免了利用 VB进行复杂的多线程编程 .

Based on full use of the on board data buffer of the A/D data acquisition card,timer control wasused to control data real time acquisition,real time display,real time process and online save,thus complex multithreading program using VB was avoided.Using form instances to store several segment data was also described.
