摘要/Abstract

摘要： 针对主从模式带来的通信延迟、冗余通信等问题,设计一种基于RS485多主对等通信方式,实现RS485通信线路上多主机对等通信功能,不需要主机轮询通信。对通信线路进行设计,在原有RS485通信线路基础上增加一条控制线路,用于检测通信线路的工作情况。移植uC/OS-Ⅱ实时操作系统到STM32F103C8T6控制板上,利用uC/OS-Ⅱ的实时多任务特性,实现通信线路检测、数据接收、数据发送及其他任务的同时运行,提高通信系统的工作效率。采用数据缓冲、数据队列、循环冗余校核(cyclic redundancy check, CRC)校验等方式,提高数据接收与发送的稳定性和可靠性,解决数据量增加带来的数据混乱、传输不稳定等问题。通过搭建试验系统,实现预期的通信功能,验证多主对等通信的可行性,为联网设备通信提供一种新方法。
