[Abstract]:At present, with the rapid development of computer network and multimedia technology, remote video surveillance is developing in the aspects of network, digitization and intelligence. The user can connect the remote embedded monitoring equipment through the network, which can not only obtain the information collected by the remote monitoring platform, but also transmit the control signal to the remote monitoring platform. In order to realize the information exchange between the user and the monitoring device. Embedded application system is the concrete product of advanced computer technology and semiconductor electronic technology. Generally, embedded microprocessors have high integration level, low power consumption and small volume, which is beneficial to miniaturization of system and enhancement of system mobility. The software of embedded system is solidified in storage medium, which is helpful to improve the speed and reliability of the system. This paper is an image and video acquisition and transmission system based on S3C2440 processor and embedded linux. The main work includes: through the requirement analysis and according to the existing development conditions, the establishment process of the arm linux system is introduced in detail. There are mainly embedded hardware platform, embedded linux configuration and compilation and related driver modification, transplantation; The collection of video data is realized, including the transplantation of USB camera driver, Boa cross-compilation and transplantation, servfox cross-compilation and transplantation, V4L application under linux and so on, and the compiling of HTML file and CGI dynamic file of boa server home page are realized. A complete video transmission system is implemented, and the development and implementation of TCP network programming are realized based on the development tools of linux. Finally, according to the network transmission structure of server / client and browser / server, the design and implementation of browser / server mode network communication are described in detail. In the test part of this paper, the comparison of two monitoring modes is carried out, and the implementation conditions are analyzed on the premise of the same or similar operation effect. The system realized in this paper has the advantages of stable performance, reliable performance, less resources, high real-time performance, and can provide excellent services in embedded applications such as image acquisition, video transmission, remote monitoring and so on. This is of great significance to the research and development of embedded network video transmission system. At the end of the paper, the shortcomings are analyzed and the direction to be improved is put forward.
