单片机与PC远程通信一种智能信号中继方法及设计

The Method and Design of an Intelligent Repeat for Remote Communication Between Microcontrollers and PC

使用现场总线 ,对于分布式测控系统中节点地址可以任意设置的主从式多机远程通信 ,如何避免中继器输出电平与指定节点位置上从机的上行数据发生信号竞争 ,本文从信号分析和电路设计着手 ,提出一种切实可行的实施方案 ,取得了良好的应用效果。

With circuit design and programming,a utilitarian method is suggested that is used in remote communication for master slave computers to avert race between singles,which output from a repeater and a node.All test result shows that the presented algorithm is satisfactory and practical to users.
