摘要
介绍了一种基于以太网的点对多分布式控制系统。控制系统以PC机作为主机,DE-311为网络服务器、单片机为数据采集和温度(参数)控制从机,实现主从式多机通信。解决了单纯的RS-485网络存在的问题,实现了远距离的数据传输与控制。
A point-to-muhipoint MCU system based on the Ethernet protocol was introduced. A host-client muhipoint communication mechanism was realized using PC as the host of the control system, DE - 311 as the network setwer, MCU as clients for the data acquisition and temperature parameters control. This structure solves the problems exist in pure RS -485 networks, realizes remote data transmission and control.
