Abstract: In view of problems of complex routing, low reliability and network congestion existed in monitoring and control system based on centralized query server, the paper put forward a design scheme of monitoring and control system based on Ethernet and embedded Web server, and introduced designs of extend of hardware circuit and software architecture of the system in details. The system uses embedded Web servers to make each monitoring and control subsystem have own independent server, adopts Ethernet to network monitoring and control subsystem, and uses gateway to connect monitoring and control network to OA LAN in mine, so as to integrate field monitoring and control network and OA network together, and make managers real-timely monitor and control information of production field by browser of PC.
