【摘要】 虚拟仪器技术作为计算机技术与仪器技术相结合的新技术已经越来越广泛地应用于测试 测量领域 ,同时 ,对虚拟仪器的软件设计也趋于标准化、可视化。本文利用统一建模语言 (UML)所提供的建模机制 ,为虚拟仪器的软件设计提供一种可视的、面向对象的设计方法 ,使虚拟仪器的软件设计更加灵活、易懂以及易扩展。文中以虚拟任意波形发生器的软件设计为例 ,详细说明如何利用UML对软件系统进行设计 ,并通过实验验证了该方法的正确性。更多还原

【Abstract】 Virtual instrument, which is a new technology combin ing computer techn ology and instrument technology, becomes more and more popular in the fields of testing and measuring. At the same time, virtual instruments’ software design te nds towards visual and standard. In this paper, we use the modeling mechanism of u nified modeling language (UML) to provide a visual, object-oriented designing me thod for software systems of virtual instruments. Such method can make the softw are designing of virtual instruments more flexible and extensible. Also we give an example to explain how to set up the software systems for an virtual signal r esources with the UML.更多还原
