Enterprise administers cannot obtain real-time production status and make real-time decision if they don’t reach the production spot. Because of the development of Embedded Web Server such status is being changed. The remote monitor and control mode based on Embedded Web Server provides complete exact real-time information for managers, and makes it possible to make a decision in real time. In the paper, the design and implements of Embedded Web Server are presented and the key realization technology of it is described in detail. EWS (Embedded Web Server) will effectively lower system operating cost and improve maintaining efficiency, which has wide application prospect and popularization value in industrial control systems.展开更多

The system consists of ECG recorders with network interface and the embedded web server, internet networks and computers, with the system operating on browser/server(B/S) mode. The ECG recorder was designed by ARM9 (S3C2410X) and embedded operating system (Linux). Once the ECG recorder has been connected to the internet network, medical experts can use the internet to access the server of the ECG recorder, monitor ECG signals, and diagnose patients by browsing the dynamic web pages in the embedded web server. The experimental results reveal that the designed system is stable, reliable, and suitable for the use in real-time ECG tele-monitoring for both family and community health care.展开更多
