基于LabVIEW与Matlab混合编程的快速波形显示

Mixed Programming of LabVIEW and Matlab for the Fast Waveform Display

该文使用NI Flex RIO设备设计实现了基于PXI架构的高速数据采集,并把采集的天文数据以十六进制形式保存在TXT文档里。由于TXT文档里的数据不能直接显示为十六进制,需要用Ultra Edit软件打开。为了实现直接读取TXT文件进行波形显示,本文用LabVIEW中的Matlab Script来实现波形的显示。实验结果表明:采用该文方法能够直接快速清晰地显示波形。

We use PXI architecture based NI Flex RIO equipments to realize high-speed data acquisition,and the collected data are saved in TXT documents in hexadecimal form. Because the data in TXT documents cannot be directly displayed as hex format,we use Ultra Edit software to directly read TXT documents and then use Matlab Script in Lab VIEW to display the waveform. The experimental results show that the waveform can be displayed directly,quickly,and clearly.
