Design of Digital Oscilloscope Acquisition System Based on LabView and GPIB

摘要:

为了满足数据采集自动化的需要,提高数字示波器的使用效率,充分发挥示波器的自动化优势,利用现有的数字示波器和工控机建立了一套数据自动采集系统；通过GPIB接口,用一台工控机对多台数字示波器进行控制,实现对信号数据的采集、处理并将处理结果存入数据库中；系统软件使用LabVIEW语言开发；实验结果表明,该系统能快速准确地获得被测信号数据并可根据需要对以往的实验数据进行查询分析,极大地方便了使用人员；采用这种方法建立的系统简单、经济、通用性强,具有一定的实用价值。

Abstract:

In order to meet the need for the automation of data acquisition, increase the efficiency of the digital oscilloscope and give full play to its advantage, an automatic data acquisition system has been, therefore, established. Through the connection with the interface of GPIB and the manipulation of several oscilloscopes by a single personal computer ,the collection and process of the signals ,and hence the result of them can be saved in database .This system was developed on the basis of LabVIEW Language. The outcome of the experiment indicates that this system can rapidly exactly capture the targeted signals and analyze the data of previous experiments according to the needs, which, to a large extent, provide the staff with great convenience. The system based on this method is simple, economical and practical, which has a significant value in use.
