摘　　要：为了办公自动化网络与工业控制网络的信息无缝集成,进而与Internet连接,实现控制系统的网络化,选择以太网作为控制网络,并搭建了单片机控制以太网网卡芯片进行数据传输实现设备通信的平台,选择电加热炉为被控对象,采用模糊逻辑智能控制方法进行控制。系统仿真结果和现场运行结果表明,模糊控制方法很好地实现了控制目的。该设计成果对推进控制系统网络化具有参考和应用价值。The Ethernet, displaced the fieldbus, used in industrial control network attract more attention in recent years, which improved control system networking. In order to fulfill office automation network signal and that the industrial control system integration seamlessly. This paper choice Ethemet as the control network, and built a communication platform which used network interface cards to transfer data, the Ethemet NICs chip controlled by single - chip computer. With the fuzzy logic control, the proposed strategy used in electrical heater system, and achieved desirable effects. The feasibility of this control strategy is confirmed by simulation and experimental results. It is a guideline for design a networking controller and has the practical application value.
