摘　　要：从发动机高空模拟试验对测试系统的要求出发,对VXI和LXI这两种总线的优势及特点进行了比较与分析,进而提出了一种新的基于LXI、VXI混合总线平台的数据采集系统的方案,并对该数据采集系统的关键技术、主要特点以及其在高空模拟试验中的重要作用进行了进一步的阐述;该系统在试验中的成功应用表明其完全满足高空模拟试验的要求,而且可以进一步提高测试系统的集成化、信息化和智能化水平及整体测试能力。To meet with the requirement of the measuring system in engine altitude--simulating tests , a new data acquisition system （DAS）, based on the appropriate combination of LXI and VXI bus , has been illistrated, of which the key techniques, the features, and the function in the tests has also been been informed in the essay after the analysis of the advantages together with characteristics of VXI bus and LXI bus respectively. It is evidenced that the new system has already fulfilled the request of the tests while being used in these tests. It can been predicted that the measuring system, equiped by the new system , can get a dramatic improvement on the capability of measurement as well as the level of the intelligence , the informatization, and the integration.
