基于LabVIEW的通用且可定制的数据采集处理软件设计

A Customizable Data Acquisition and ProcessingSoftware Design Method Based on LabVIEW

摘要:

数据采集系统可将外界模拟信号转换成数字信号并输入计算机,随后在计算机上进行后续数字信号处理[1]。在实际应用中,待采集的模拟信号一般来自各类物理场传感器,针对不同的应用场景、不同的传感器、不同的项目需求,一般需要定制化开发数据采集系统。得益于NI(National Instruments,美国国家仪器)公司开发的通用化硬件采集设备,用户在数据采集项目开发时只需着重考虑软件部分的设计工作,本文提出一种基于LabVIEW编程语言的通用且可定制的数据采集处理软件设计方法,即考虑可用于多个数据采集项目的通用性,又满足不同项目的定制化需求,注重软件复用性,提高项目开发效率。

Abstract:

The data acquisition system can convert analog signal to digital signal and input it into the computer. In practical applications, in view of different application scenarios, different sensors, and different project requirements, a customized data acquisition system is generally required. Thanks to the universal hardware acquisition device developed by NI (National Instruments), the user only needs to consider the design of the software part of the data acquisition project. This paper proposes a data acquisition and processing software design method based on the LabVIEW programming language. The method considers the versatility, focuses on software reusability, and improves project development efficiency.
