摘要
针对工业实际中某液压伺服机构,设计了一种具有多功能、高可靠性的新型计算机测控系统;方法是结合液压伺服机构中执行器件及被控对象的特点,采用双总线多计算机协同控制的方式对传统的计算机测控系统进行改进和优化以提高数据处理能力,并通过NI公司的LabWindows/CVI软件建立数据采集与系统监控平台,实现人机交互。经过在实际工业现场长时间运行,证明该系统的动态精度能达到±5%,静态精度能达到±1%,并能连续工作至少8小时,达到了技术指标要求;这也为同类伺服机构控制系统的开发提供了现实依据。
This paper designs a new type of computer measurement and control system for a hydraulic device which has the advantages of multi--function and high reliability. Combined with the features of execution element and controlled object, adopting dual bus and multicom- puter coordination control depending on the traditional control method to improve the data processing capability. Establish data collection and system monitoring platform based on the LabWindows/CVI to realize human--machine exchange. The designed system can achieve the qualification that are ±5% dynamic precision. ± 1% static precision and over 8 hours work time after a long time working in the industrial site. The method also supplies reality basis for other servo control system.
