基于PXI体系的分布式数据采集系统设计

A distributed data acquisition system using PXI architecture

PXI是PCI在仪器领域的扩展,目前广泛应用于制造测试、军事和航空、机器监控、汽车生产及工业测试等各种场合.本文介绍了基于PXI体系的分布式数据采集系统的3种设计方案,包括硬件设计方法及相应的软件开发,并分析了3种方案各自的优缺点,为实际工程应用提供了一定的参考.

PXI is an extension of PCI bus in the field of virtual instruments. At present it is used widely in process of manufacturing and testing, etc. This paper introduces three design schemes for a distributed data acquisition system based on PXI bus, including the design methods of hardware and the corresponding development of software. Both the advantage and disadvantage of each scheme were analysed, providing certain reference for actual engineering projects.
