摘要
现场总线技术中的节点是现场设备或现场仪表 ,但它们已经不再是传统的单功能的现场仪表 ,而是具有综合功能的智能仪表。文中首先介绍了LonWorks现场总线技术中关于节点的一般设计原理 ,而后以有毒气体检测智能节点为例 ,详细说明了它的工作原理、硬件电路设计以及软件设计。
The node in fieldbus is just an instrument or equipment on spot,but it is no longer an conventional instrument which has single function.It is an intelligent instrument which has compositive function.The article firstly introduces the general design principle of the node based on LonWorks fieldbus, and give an example of toxic gas detection intelligent node.Also the article explains its functional principle, hardware circuit and software design.
