摘　　要：针对某试飞课题,在NI LabVIEW7.0平台下进行了某试飞科目实时监控软件系统开发。飞行试验中,实验分析了影响该系统试飞参数时间历程图实时刷新的原因,提出了在飞行试验实时监控中,采用优化VI及对Chart控件二次编程的方法解决Chart曲线图实时刷新的问题。在此充分挖掘LabVIEW中Chart控件的属性进行二次编程,解决试飞参数时间历程图实时刷新、显示问题,具有很高的实用价值。A software of the realtime monitoring system is designed on NI LabVIEW platform for a certain course of flight test.The causes which affect test flight parameters of the system,the real-time update of time process chart,were analysed.A method to optimize VI and reprogram the Chart control is adopted to solve the real-time update of Chart curve graph in the real-time monitoring during flight testing.The innovation of the paper is that it makes full use of the Chart＇s property to carry out the secondary program,which puts the axe in the helve and has high practicality.
