The Design And Implementation Of Mobile Remote Video Surveillance System Based On Linux

In recent years, due to the progress of embedded and network technology, many kind of equipments were headed in intelligent, network and integration direction. At the same time, electronic equipments were applied into all aspects of life, not only providing various convenient to human beings, but also providing enormous economic benefits for society. With the development of embedded and computer technology, broadband penetration, video monitoring system has become a new hot spot in the visual field.This paper has proposed a moveable remote video monitoring system based on Linux towards the present ones in the market with the disadvantages of routing, hard to develop, high cost, and its limited transmission distance, not smart enough. The smart system takes Embedded Web technique and streaming media technology as its core, and takes wireless networks as its transmission medium. It has a moving target detection, intelligent message alarm, scene image playback, remote mobile function and so on. Can realize no one stick, patrol at the scene. At the same time the system is simple wiring, easy to upgrade, with strong practicability.The system adopts a microcontroller of S3C2440 to process data and a UVC camrea with friendly supporting by Linux to collect data. As well as WIFI wireless net adaptor to transmit image data. The embedded Web and video servers are realized in the Linux environment, after the embedded Web server receipt the HTTP request from the user, the video data of video server is sent to the remote client in the form of Web page, Authorized users can watch live video data via a browser on the computer, set up the system parameters and remote control devices moving and so on. This paper first presents the overall scheme of the system design, then expounds the construction of the embedded development environment, the transplantation of the Bootloader and the Linux kernel, the manufacture of the file system, the design of alarm lamp, dc motor, the USB camera and wireless network card driver program file. Following, conducts the Boa, motion video server, Web server, mutt, msmtp, wpa_supplicant related software compilation and transplantation. Finally, this paper introduces the concrete operation of the equipment and tests the design effect.
