Abstract: The embedded Web technology is contributing to reducing monitoring system cost and improving system reliability greatly, so the remote image monitor and control system based on ARM will become new research focus. This paper presents a hardware design of a kind of monitoring control system based on embedded Web technology, the design realizes the online remote supervision, management and maintenance, using a standard Web browser over Internet without timespace constraints. An ARM7-core processor AT91SAM7X256 is selected as a control chip in embedded video network server, with video signal captured by CMOS image sensor OV7640 and message transmitted by network module RTL8021BL. Practical results demonstrate the favorable stability and real time characteristic of the hardware system which can meet the most of network application demands and is worth popularizing.

Key words: ARM, monitoring system, AT91SAM7X256, OV7640, RTL8021BL
