For Pxi Bus-based Aviation Research And Design Of The Distribution System Test Platform

The aircraft power system is one of the most important equipments of modern aircraft, whose stable running is the key factor for the safe flying of plane. The testing and analysis in the way of accurate and fast to the performance parameter of the aircraft power system having very important significance and value.This article take the aircraft power system performance parameter test as the main object of study, has used the advanced PXI main line test system, designed the aviation power system test platform based on the PXI main line, to realize aviation alternating current and direct current power system the performance parameter test and the analysis.This article first to the test platform overall structure and each control section which designed based on the PXI main line has carried on the introduction, introduced in detail based on the PXI main line technology data acquisition and processing system each part of design, the configure and the integration, this article has carried on the detailed narration to each part of concrete design process, and has given each subsystem concrete design project;Has designed the corresponding algorithm in view of the aircraft power system parameter test concrete characteristic, and to the basic data acquisition algorithm, like the FFT algorithm, the parabola interpolation, the harmonic analysis, the linear fitting algorithm, the load automatic manage algorithm and so on, has carried on the detailed description and the explanation;On the basis studying to the algorithm, used the object-oriented programming language to carry on the software design, has given the software flow diagram and the solving process for some key question.This article key point placed to has used the PXI main line technology to carry on the hardware configure and integration design project...
