LabVIEW在虚拟仪器远程数据采集系统中的应用

The Virtual Instrument Remote Data Acquisition System Based on LabVIEW

针对复杂的测试系统的数据采集方法的局限性,提出了一种基于虚拟仪器的远程数据采集系统的软件设计方法,介绍了网络化虚拟仪器及其软件开发平台LabVIEW。运用LabVIEW开发了用于远程数据采集的虚拟仪器,并阐明了其网络协议、硬件、软件设计原理。利用服务监听机制和datasocket技术,通过局域网开发该虚拟仪器可实现网络测试数据的实时发布与读取。

Aiming at the localization of data acquisition method of the complex testing system, the paper brought forward a software designing method of remote data acquisition system based on the virtual instrument. The virtual instrument based on network,and its software development platform LabVIEW were introduced. The virtual instrument for remote data acquisition was developed by means of LabVIEW.The network protocol and the design principles of its hardware and software were also illuminated. Using serve monitoring and datasocket technique, this virtual instrument can achieve real-time publishing and reading of network test data through the development of local area network（LAN）.
