基于PXI总线的飞机交直流电源综合试验系统研究

摘要

Because it is difficult to measure the parameters of airplane AC & DC power supply due to its complex structure and lots of data types,mass data quantity,by means of computer control technology,a comprehensive test system based on PXI bus and LabVIEW virtual instruments technology was designed for airplane AC & DC power supply. The probation result shows that the test system has the advantages of multi-function,strong universality,multi-channel synchronous sampling,mass data strong ability, high dynamic and static performances,and high real-time performance.%飞机电源系统结构复杂，被测的数据类型多、数据量大，检测难度大。利用计算机测控技术，构建了一套基于PXI总线和LabVIEW虚拟仪器技术的飞机交直流电源综合试验系统。经试用证明，该试验系统综合化程度高，通用性强，可以实现多通道数据同步采样、数据存储量大、动态和静态性能好、实时性强。
