Study And Design Of Web Video Surveillance System Based On ARM/VxWorks

The monitoring system known little few yeas ago has entered our daily life and becomes well-known to the public nowadays. The monitoring technology has been developed into the third generation, the fully digital stage from the first generation, the fully analog system stage. As the development of the microprocessor technology and network technology, the web-based embedded network video monitoring system arouses widespread interest gradually, and the network-based digital video surveillance system has been developed into the mainstream of video surveillance system fields.Based on the analysis of the current situation and development trend of video surveillance, this thesis designed a better application programme from the market prospects to improve the inadequate existing systems. The programme desires to implement an efficient and rapid response embedded video surveillance server, which is established on the popular microprocessor ARM9, using strong real-time operating system VxWorks, with the integration of high-performance open-source embedded web server and embedded database. The system can support USB video device, IO operation in file system, database management. Therefore, it has a highly performance-price ratio.Further more, this thesis described hardware and software framework of the video surveillance system, focused on the porting of embedded operating system VxWorks onto S3C2410 board, implemented the corresponding driver after the analysis of flash file system, mechanism of Ethernet cards, USB stack protocol. After the implementation of the RTOS VxWorks, it succeeded completing the porting of embedded Web Server GoAhead and embedded database Berkeley DB. Meanwhile, it also designed and implemented the CGI application modules. The designed programme in this thesis is a good combination application of ARM, Network and RTOS VxWorks in the embedded system which can be used in the other areas such as traffic control, real-time detection, security checks, and it may also provide great reference value for the other fields.
