基于LabVIEW的中子注量率密度数据采集

Neutron Flux Density Data Acquisition System Based on LabVIEW

在LabVIEW软件中,结合PCI-6251数据采集卡,采用DAQmx数据采集函数实现中子注量率密度数据采集的虚拟仪器VI设计.虚拟仪器VI包括前面板和程序框图部分,采集到的数据能够以数据曲线和数据显示控件两种形式显示,并以文件的形式保存数据.测试结果表明,该系统能够准确测定NI ELVIS输出信号频率,实现基于LabVIEW的中子注量率密度数据采集.

In the LabVIEW software,combined with PCI-6251 data acquisition card,VI of neutron flux density data acquisition is realized by DAQmx data acquisition functions.VI is composed of front panel and block diagram.The data collected can be displayed in the forms of the data curve and the data control,and saved in the form of files.Test results show that the frequency of output signal in NI ELVIS can be accurately measured by the system,realizing neutron flux density data acquisition based on LabVIEW.
