摘要
串口传输是目前应用比较广泛的数据传输方式,其中RS485总线以其结构简单传输速率快等特点成为重点研究课题之一。从数据传输协议、数据传输方式、消息帧格式、错误检测方法几个方面考虑,设计出一种基于RS485主从串口为物理传输媒介的主从传输协议,并详细给出了协议各模块的设计实现。
Serial transmission of data transmission is widely used at present, the RS485 bus with the characteristics of simple structure and high transmission rate has become one of the key research topics. Considering from the data transmission protocol, data transmission, message frame format, error detection methods in several aspects, to design a master-slave transmission protocol based on physical transmission media of the RS485 master-slave serial, and gives the design and implementation of protocol module.
