基于航天测试技术的LXI多功能接口板卡设计

LXI作为一种较新的测试总线一经推出就受到了自动测试领域众多科研院校和企业的关注,并在众多领域取得了广泛应用。为了进一步提高航天测试系统的结构通用性、设备互换性,缩短测试系统搭建周期,填补航天测试系统LXI接口设计的空白,采用软硬结合的系统构架,提出了一种LXI多功能接口板卡的设计方案,总结了核心技术1588时钟同步协议和IVI驱动的实现方法,该设计方案对LXI总线技术在我国航天测试领域的应用具有一定的指导作用。

Design of LXI multi-functional interface card based on aerospace automatic testing technology

Aiming at improving the structure generalization and instrument interchange ability of the aerospace automatic test system,reducing inventory of the test system,and filling the blank of the LXI interface design of the aerospace automatic test system,the system architecture combining hardware and software is used. A design scheme of the LXI multi-functional interface card was put forward. The implementation methods of core technologies of IEEE1588 clock synchronization protocol and IVI driver was summed up in this paper. The design scheme will play an important role in application of LXI bus technology in the aerospace automatic testing system.
