基于串行总线的测量仪器模拟节点设计

Anolog nodes signal monitoring techonology base on serial bus

模拟节点作为智能测量仪器监测内部工作状态的重要渠道,是智能测量仪器设计的重要组成部分。在综合分析智能测量仪器模拟节点设计思想的基础上,针对当前需求提出一种基于串行总线的模拟节点信号监测设计方案,并阐述了其设计要点和注意事项。

Analog nodes have always been the important way of monitoring the internal status of instruments, and have always been the key part in intelligent instrument. The paper first generically analyzes the idea of intelligent instrument＇s analog nodes design： then submitsa signal monitoring scheme of analog nodes based on serial bus; finally, the paper expatiates the design cruxes and considerations.
