嵌入式系统在传统PLC控制系统中的应用
The application of embedded system in traditional PLC control system
【摘要】 介绍了以AT90mega8515嵌入式单片机构成的单总线温湿度采集系统在PLC控制网络中的应用,以及通过OM鄄RON公司PLC构建的HostLink控制系统,实现对下层PLC的监控。系统的高性能上位机同时为嵌入式系统提供了应用接口。运用C++Builder6.0编制可视化监控软件并通过多线程技术提高系统响应速度。
【Abstract】 It is introduced how the 1-wire data collection system based on embedded MCU (AT90mega8515) to be used in the traditional PLC control system. The Host Link control net constructed with OMRON PLC complete monitoring the substrate PLC. In the mean time, the high-powered upper PC support the application of the embedded system. The visible monitoring software is organized with C++Builder6.0, and the response speed is improved by the technique of multithread.
