基于LabVIEW7.0的某实时监控软件设计与实时性分析

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。

Design and Analysis of Real-time Monitoring Software Based on LabVIEW 7.0

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 progr...
