基于LabVIEW的数据采集与反馈控制通讯系统

Feedback Control Communication System Design Based on Data Acquisition and LabVIEW

针对传统的转子振动测试方法所需仪器较多、可靠性较差和成本较高等缺点,基于虚拟仪器技术,利用Lab-VIEW强大的图形化编程环境和adlink公司的数据采集卡,开发了一套先进的数据采集与处理系统。该系统以转子为研究对象,实现了多通道的数据采集、数据实时分析和数据保存等功能,同时利用LabVIEW中的VISA模块,完成了对转子转速的反馈控制。试验结果表明:系统操作简单,运行稳定,可扩展性良好,是一款功能强大、性价比高的分析软件。

Traditional rotor vibration testing methods required more instruments,but the reliability is poor and cost is high.Based on virtual instrument technology,this paper used the LabVIEW powerful graphical programming environment and data acquisition card,developed an advanced data acquisition and processing system.The system took rolor as the research object,realized the multi-channel data acquisition,data real-time analysis and data storage.Meanwhile,it use the VISA module,realized the rotor＇s speed feedback control.Test results show that the system operate simply,run stably,scalability is good,it is a powerful and high quality analysis software.
