Abstract:

With the rapid development of the Internet, remote control of the movement of devices through the Internet has become a research focus. The article pr esents a design that can connect a device to the Internet directly through an embedded Web server. Taking the example of the remote control of step-in e  lectromotors, we design a minimal functional embedded Web server on ARM. It analyses the Internet packets and achieves the control information which is   included in the HTTP data. According to the control information, the way of counter interrupt is adopted to control the eleetromotor. On this basis, theremote control system for step-in electromotors on ARM is implemented.

Key words: （distributed long-distance movement control, embedded web server, TCP/IP protocol reduction）
