Abstract:

Aim at the problem of lacking portfolio and integrate about the current monitor and alarm systems, an embedded intelligent monitor system based on ARM（Advanced RISC Machines） was proposed. The system uses an embedded WinCE operating system,S3C2440 processor of ARM and 13 million pixels CMOS（Complenmentary Metal-Oxide-Semiconductor） camera, which are composed of video capture device. The combination of the background subtraction and frame difference method,the method of adaptive updating background was proposed to detect moving object. Finally, the alarm information is sent by way of mobile email and mobile phone connected through SMTP（Simple Mail Trasport Protocol） and MIME（Mutipurpose Internet Mail Extension） transmission protocol. When someone broke into the monitoring sites,the systems can alarm on their own, and transmits the captured video information to the user hand side through the network. The experimental results showed that the intelligent monitor system has the high efficiency, rich interfaces and the higher security and reliability.
