基于PXI总线技术的飞机电气综合测试系统

Synthesis Test System of Electronic Equipment Based on PXI Bus Technology

为了对飞机电气系统进行综合测试,文章结合飞机电气系统测试需求及PXI总线特点,描述了飞机电气综合测试系统开发过程。论文中介绍了组建系统选用PXI总线技术作为开发平台的依据,给出了系统的总体结构及所需硬件测试资源,描述了系统软件开发选用的特有组织结构并论述了组件技术在这种组织结构中的应用情况。系统的开发结合了PXI总线优势,具有良好的开放性;组件技术的使用,提高了系统开发过程中代码的重用率。系统的使用可同时满足不同机型电气系统的综合测试需要。

In order to illustrate the reasons of applying synthesis test system on the electric system of plane,the characters of requirements of electric system and the PXI bus are introduced, and the process of development of the synthesis test system is described. At the same time, it explains why choose PXI bus technology as the exploitation basic of the system, and then describes the main structure of the system, requiremental resources of the hardware, and the special structure which is used in the software design, and the current situation application of the component technology into the system structure. The paper finds out that using the advantage of PXI bus, there will promote the system to be more opening. Moreover, using the component technology will improve the codes` efficiency of reusing in system exploration. Finally, author believes that using the new system will meet the demand of the synthesis testing in different styles of electric systems.
