基于差分信号全双工数据通信的中断技术研究

以差分方式平衡信号实现全双工数据通信的分布式测试系统，在扩展通信距离和节点数量时，如何保证节点地址可以任意设置，如何避免中断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、电路设计着手，提出不同连接方式下几种切实可行的实施方案。

Study of repeater based on differential mode signal used for full duplex data communication

With the signal analysis and circuit design, we suggest a utilitarian method for two topological sorts. That is used in distributed system of measurement and control. By the method, system is able to avert race between singles, which output from a repeater and a node. All test results show that the presented algorithm is practical.
