由计算机平台和专用的硬件、软件所构成的虚拟仪表测量技术是当今测量技术的发展方向,具有操作方便、可靠性高、适应面广等特点。基于虚拟仪表控件的软件设计思想,结合无人机仿真试验中各系统模块产生的数据特点,使用GDI+图形绘制技术,采用VC++编程语言开发出具有美观、通用等特点的虚拟仪表控件,并成功应用于某型无人机地面飞控测试系统中。而且利用文中所实现的图形控件库可以很方便、快捷地开发出针对不同数据类型的虚拟仪表,可根据需要应用到各个领域的工程测量中。
The virtual instrument measurement technology composed of computer platform and special hardware and software is the development direction of measurement technology today. It has the characteristics of easy operation, high reliability and wide adaptability. Based on the software design idea of the virtual instrument control and the characteristics of the data generated by each system module in the UAV simulation experiment, this paper uses the GDI + graphics rendering technology to develop the virtual instrument control with the characteristics of beauty and universality using the VC ++ programming language. In a type of UAV ground flight control test system. Moreover, the graphical control library implemented in this paper can be used to develop virtual instruments for different data types conveniently and quickly, and can be applied to engineering surveying in various fields as required.
