多节点UART通讯的研究及其在空调系统的应用

Research on UART Communication With Multiple-nodes and Its Application in Air-conditioning System

本文研究了一种新式多节点UART通讯电路拓扑结构,解决了UART只能一对一单点通讯的难题,开创式革新为行业内主流通讯方式节省了成本。经过实验分析,该种通讯方式可靠性高,可应用在空调系统上及其他类似需要一主多从的通讯场合。

In the paper, it researches a kind of new UART communication circuit topology with multiple-nodes. It solves the difficulty of UART that only one to one node can be connected now, so as to save the costs of main com- munication methods in the industry. The new topology of UART has high reliability through experiments and analy- sis, which can be applied in air-conditioning system and other similar situations.
