摘要
针对增压连续式风洞扫描阀测量系统的实验,设计了一种基于虚拟仪器LabWindows/CVI开发环境下的风洞扫描阀系统实验数据采集系统,阐述了该系统的方案设计,给出了系统的主要软件涉及构成及采集流程图。该系统为用户提供友好的人机交互界面和易操作性,完成对扫描阀测试实验系统模块参数、系统扫描参数、触发模式的信息配置,实现了对压力测试各通道数据的实时测量、显示、保存及打印输出。实验结果证实该系统提高了测量的有效性和可靠性。
This paper presents the data acquisition about scanning valve system in wind tunnel test which is based on the virtual instrument environment,such as the LabWindows/CVI.The test system provided a good measure interface for the users by the LabWindows/CVI and completed the information configuration about module parameters of the system,scanning parameters of the system and trigger mode.It also provided a real-time measurement,display,save and print output about the channel measurement which can selected in the stress testing experimental system.This system possessed a friendly man-machine interface and easy maneuverability,it greatly increased the effectiveness and reliability of measurement.
