摘要
针对传统火工品电阻检测方法的缺陷及其存在的安全隐患问题,研究设计了一种远程通用火工品检测仪。整个检测仪以工控机为控制核心,以PCI总线为基础,利用PCI总线在数据采集的功能卡和系统内存之间实现多通道数据采集以及对板卡的控制命令;工控机在图形化编程语言LabWindows/CVI平台下控制PCI实现数据采集、开关量控制及对所测数据进行计算、分析、显示、判断;根据测试结果利用软件补偿方法使用曲线拟合的方式进行误差处理。应用结果表明:该检测仪具有使用方便、测量范围宽、精度高的优点。
Aiming at the problem that the defects and safety hidden danger of the traditional resistance measurement for initiating devices ,a long‐range general tester for initiating devices is researched and designed .The whole tester is de‐signed around industrial‐control unit as control core .PCI bus ,as basis of the tester ,is used to sample the multi‐channel data between data acquisition card and system memory ,as well as the control commands to volume car .The industrial‐control unit will control PCI to achieve data sampling ,switching volume control and the calculation ,analysis ,display and judgment of the measured data that via the graphic program language LabWindows/CVI environment .The tester using software compensation method with curve fitting is used for error handling .The application showed that the tester is easy to use ,and it has wide measuring range and high precision .
