Feedback Control Communication System Design Based on Data Acquisition and LabVIEW

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.
