【摘要】:针对物联测控技术面对对象多种多样以及物联网络构成复杂、实时性低等不足,以片上系统C8051F20为核心,基于FreeModbus协议设计了一种支持多接口、集约化、本机可编程的智能物联终端。终端支持Modbus RTU、Modbus TCP数据通信,可与上位机无缝对接,实现远程监控,又可灵活连接现场传感器和执行器。同时,系统移植了μC/OS-Ⅱ操作系统并采用μC/GUI进行用户界面搭建,软件中设计有逻辑编程功能,实现了本机可编程。使终端能同时进行远程测控和现场实时逻辑控制,同时缩减了通信量、降低了网络复杂程度,解决了测控实时性问题。实际应用表明,该终端工作稳定可靠,编程操作简单,实时性好,适应性强,达到了实用要求。
