摘要
为了增强无人机系统检测控制设备的通用性,提高检测精度,设计了一种基于面向仪器系统的PCI扩展(PXI)总线及虚拟仪器(VI)的无人机通用综合检测系统.针对无人机系统工作的特点,从功能设计、体系结构、软硬件设计等方面对该系统的通用性进行了探讨.该系统采用了虚拟仪器技术,硬件设计采用PXI体系结构,软件以LabWindows/CVI作为开发平台.通过配备不同的接口适配器和对软件参数设置进行相应更改,可适用于不同型号的无人机电气、舵机、发动机、起飞和回收等系统检测.同时提供矩阵输出,利用系统资源满足无人机各种信号测试/激励的需求.该系统已成功应用于某复杂型号无人机的地面综合检测.
A general integrative test system of UAV（unmanned aerial vehicle） was designed to improve the general capability of integrative test system of UAV and to increase the test system＇s precision of testing. The general capability of this system was developed in aspects of design of software and hardware, the structure, and the functionality. This system adopted the VI（virtual instrument） technique. The design of hardware based on PXI（PCI extensions for instrumentation） construction and the platform of software was LabWindows/CVI. By changing the interface adaptor and the parameter settings, the system could be used in testing most subsystems of different types of UAV, such as electrocircuit, actors, engines, and so on. The system also provided an output matrix to meet the test requirements. This system was successfully used in the integrative testing of a complicated UAV.
