总线类测试系统的技术现状及发展方向

摘要

ABSTRACT:The work generalizes the mainstream bus architecture form of current testing systems and analyzes their perfor-mances and applications. It researches the main software design techniques state for current test systems and then puts forward the main direction of future development of testing system. To satisfy future complex test requirements, the main design direc-tion of test systems is to develop large-scale and high precision mixed test systems based on LXI bus. In the aspect of hardware design, VXI/PXI/PXI-Express/PCI-Express/USB3.0 bus will be integrated by local area network to satisfy low-speed, high-speed and high precision data acquisition and transmission requirements. In the aspect of software design, it is necessary to research and develop a software system that has completed functions and can meet the needs of special applications according to industrial standards and needs.%归纳了当前测试系统的主流总线架构形式，对当前各种总线架构的测试系统性能及应用进行了分析，同时对当前测试系统的主要软件设计技术现状进行研究。在此基础上，提出了未来复杂测试系统研制的主要方向，要满足未来复杂测试任务需求，应加大应用LXI总线构建大型高精度混合型分布式测试系统。硬件方面，将VXI/PXI/PXI-E/PCI-E/USB3.0总线进行组网集成，满足大型应用测试中低速、高速、高精度的数据采集与传输测试需求；软件方面，应按照行业标准需求，研制功能完备、满足特定行业应用的软件系统。
