基于现场总线技术的虚拟仪器开发

Virtual instrument development in Field Bus

虚拟仪器(virtualinstrument)是基于计算机和准总线技术的模块化系统。现场总线(FieldBus)是指用于现场仪表与控制系统和控制室之间的一种全分散、全数字化的智能双向、多变量、多点、多站的通信系统。基于现场总线的虚拟仪器,具有经济、高效的特点。虚拟仪器的利用可视化编程环境,建立通用的图形化软面板,可实现测量仪器的自动化、智能化。在现场总线技术得到广泛应用的今天,基于现场总线的虚拟仪器的开发具有十分广阔的市场前景。

Virtual Instrument is modularization system based on the computer technology and Field Bus technology. Field Bus is the communications system which is intelligent,muh-variable,mult-point,muh-station. Virtual Instrument based on Field Bus is economic and high efficiency. By this technology, it realize measure instrument automatization and intelligentize. Field Bus widely application in industry, Virtual Instrument based on Field Bus is forecasted to be welcomed in market.
