摘要
采用基于PX I总线的虚拟仪器技术和以太网分布式测试技术,设计了新支线飞机ARJ21供电特性综合测控系统。采用Datasocket、VI Server及Remote Panel技术实现基于以太网的采样数据的实时交换;通过同步采样和时间同步系统实现分布式采样数据的同步记录,为分析试验数据的相关性提供了便利。实际运行表明系统大大地提高了系统试验的效率。
By adopting virtual instrument technology based on PXI bus and Ethernet distributed test and control technology, an integrated power supplying characteristics test and control system for new ARJ 21 regional jet is designed. The real time sampling data exchange based on Ethernet was implemented with technologies of Datasocket, VI Server and Remote Panel ; and synchronous recording of the distributed sampling data was realized through synchronous sampling and timing synchronous system. These provide convenience to analyze the correlation of the test data. The practical operation shows that the system meets predicted test requirements and the efficiency of the test is greatly enhanced.
