一种基于LabVIEW的大型测控软件数据传递方式的研究

Data Transfer Mode for Measurement and Control Software Based on LabVIEW

LabVIEW基于数据流的运行模式,容易造成各模块紧密耦合,限制了其在大型测控软件系统开发中的应用。针对LabVIEW的特点和不足,结合发布者/订阅者通信模型,提出了一种适用于大型测控软件中各模块间数据交互的“无线数据流”传递方式。这种数据传递方式继承了发布者/订阅者通信模型在时间、空间和同步方面的非耦合性,实现了大规模系统各模块间动态灵活的数据交互,提高了系统的可伸缩性和模块的可重用性。

LabVIEW traditional closely coupled dataflow increases and control system.This paper aims at the characteristic and the difficulty of using LabVIEW in large-scale measurement shortage of LabVIEW,uses the publisher/subscriber communication model to present a wireless dataflow transfer mode for the data interaction between the modules in large-scale measurement and control system,This data transfer mode inherits the time,space and synchronization decoupling form the publisher/subscriber model,realizes the dynamic flexible interaction between the modules in large-scale system,improves the scalability of the system and the reusability of the modules.
