| New surveillance system technology will bring better accessibility, greater flexibility and remote monitoring function.Engineering and technical staff, managers or debugging through the Web instead of in person at the scene can be remote data, monitoring and control equipment as well as control, calibration, and so on. Based on the network monitoring system is a key embedded devices. Server should be able to capture video data transmission through the network and client to achieve acceptable video and data to commands sent to the server, remote control features.This paper is based on the application requirements, design and development of a network video monitoring system for portable equipment. This paper gives the system hardware and software design program, analysising based on ARM9 embedded Linux system,design and implementation of bootLoader,transplanted the Linux 2.6 kernel, construction of the root system and embedded GUI environment.Through USB video capture of the principles and standards of the V4L(video4linux) study deeply,achieving a stable USB video capture,developing this servfox of server software and the spcaview of client software.Taking into account the client may be Linux or Windows operating system,developing the client software for two kinds of spcaview,one uses in the linux system, Another development with the use of Visual C++6.0 and windows systems.Spcaview can control,storage and grabbing pictures. I transplanted the konqueror browser and server Boa, convenience of the remote control system and other control networks for the follow-up and made preparations. Finally, this paper presents a lot of opinions. |
