介绍了Windows下核燃料棒芯块间隙和弹簧空腔无损检测设备的软件设计,该软件采用多线程技术控制研华PCI-1780采集卡定时采集前端探测器输出的透过核燃料棒的7射线信号,针对采集数据的特性,进行相应的处理和分析,可以准确地检测出核燃料棒中芯块间隙的大小、位置以及前端弹簧空腔的长度.该软件经过实验验证在检测速度为8时,能够准确测量芯块间隙和弹簧空腔的长度,并向PLC发送相应信号实现自动分选.目前已应用在核燃料元件厂的核燃料棒芯块间隙和弹簧空腔无损检测设备上.

It introduces a software design of nuclear fuel pellet gaps and spring cavum nondestructive test equipment based on Windows pladorm.It used multithread technique to control Advantech PCI-1780 counter/timer card,and collect γ-ray signal from front detector.Process and analyze the collected data can exactly check the width and position of inter-pallets gap and the length of spring cavum.The software can measure the pellet gaps and the cavity length of spring accurately,and send customizing messages to PLC which complete automatic sorting,at 8 m/min detection speed.Now the software system is used on nondestructive test equipment in Nuclear Fuel Element Factory.
