【摘要】 本文以软件重用的设计理论为依据，对“基于组件技术的虚拟仪器开发方法”进行了深入的研究，文中涉及基于组件的虚拟仪器技术和液压测试技术两个方面，研究的主要内容及取得的成果如下： 1、论文分析了国内外基于组件的虚拟仪器技术的研究现状，研究了组件的接口技术，设计了幅值可调、界面可变的示波器和数字表等常用的组件，开发了用于电液伺服阀静态性能测试的液压CAT专用组件，上述组件可用于电液伺服阀的压力特性测试、流量特性测试和静耗特性测试，能较好地满足试验系统的需要。 2、研制了用于电液伺服阀动态性能测试的组件——波德图组件，该组件横纵坐标均可调，即频率范围、幅值范围、相角范围均可由用户自行设定，适用于多种型号的伺服阀动态特性测试。 3、首次将基于组件的虚拟仪器开发方法和虚拟仪器平台引入电液伺服阀性能测试系统中，使得软件的升级和管理更加方便，并使测试、计算、控制及故障诊断等更灵活，功能更强。 4、将所开发的虚拟仪器组件应用于“金属结构疲劳试验系统”中，缩短了软件的开发周期，在重点实验室的验收中，取得了良好的效果。 5、对基于网络环境的虚拟仪器技术进行了探讨，构建了网上虚拟实验室的基本框架。更多还原

【Abstract】 On base of reuse software design theory, this thesis studies the "Component-based Virtual Instrument Development Methods". Two researches of component-based VI technology and hydraulic testing technology are included in this paper and main problems researched and achievement acquired are listed below:1. The thesis analyzed the present condition of component-based VI technique, studied the interface technique of component, designed some components which have changeable coordinates, changeable colors and changeable interfaces, such as digital meter, oscillograph panel. In addition, the author developed controls which could be applied in the static character testing system of electronic-hydraulic servo valve, including pressure character testing, flux character testing and static leak character testing.2. Studied the component development used in the dynamic character testing systemof electronic-hydraulic servo valve------BDT control. Its frequency range andangle range can be changed arbitrarily, and it is adapt to test the character of all kinds of servo valves.3. For the first time, The paper leads component-based VI development methods and VI flat to electronic-hydraulic servo valve test system, which makes the management and upgrading of software easier, and makes it flexible to test, calculate, control and diagnose troubles.4. Applied VI components to ’metal configuration prostration test system’ , which made testing system developed quickly. It had acquired excellent effect in the inspect of pivot laboratory.5. Explored the technology of VI based on the network circumstance, built the basal frame of virtual laboratory on the web.更多还原
