LXI C类仪器的设计与实现方法

LXI C类仪器的设计与实现方法:：简述了I XI总线技术产生的背景及LXI仪器的特点，并根据国际LXI协会制定的LXI标准(v1．o)分别对A、B、C三类仪器标准进行了介绍，为了将LXI总线技术应用在现有的测试平台中，提出了一种将传统仪器升级为符合C类标准的LXI仪器的方法，该方法以现有仪器为基础，与带有Web Server的基于单片机的嵌入式网络接入模块相结合，成功地将传统仪器升级为符合C类标准的LXI仪器，在程控电源上进行的实验验证表明，应用该方法设计实现的LXI仪器模块符合LXI C类仪器标准，且具有成本低、结构简单和通用性强等特点。

Abstract：The technical evolution of LXI bus technique and the characteristics of the LXI instrument are discussed．According to the I XI Standard v1．0 of LXI Consortium，the A，B，C，three classes LXI instruments are introduced respectively．To apply LXI bus technique to the existing test platform ，the method of traditional instrument upgraded as the LXI instrument that matches standard of LXI Class C is presented．The method takes existing instrument as the foundation，combining with the single-chip microcomputer that has W eb Server am bedded Ethernet module，realizing upgrading、The result of experiment on the program control power shows that by using this method，the design and realizing of LXI instrument match the LXI Class C instrument standard，and have the strong characteristics of low cost，simple
structure and general use．
