Abstract


With the development of embedded technology and digital video technology , the monitoring system is also continuous innovation . The front-end integration , video digitizing , monitoring network , the system has become an integrated video surveillance system recognized the development direction . Network video monitoring system combined with embedded video processing technology and network communication technology , the better the image quality and can be transmitted through the network . Has been widely used in living quarters security monitoring , bank security surveillance , highway traffic safety monitoring . The topic is based on TI's TMS320DM6446 dual core (ARM DSP) video processor chip , design and realize an integrated network camera . Integrated network camera is an important part of the network video surveillance system camera it can be collected from the analog signal is digitized and compressed processing , after which the processed video file transfer to a remote server through the network interface . First described the course of development of the monitoring system , briefly describes the structure and function of the integration network cameras and research significance . Followed by a detailed analysis of the functional and structural characteristics of the TMS320DM6446 dual-core video processor , combined with the functional requirements of the integrated network camera based on the overall design and processes . Details the design process , the debugging process and the main function of the camera hardware platform module debugger module design , and given two types of problems encountered in the process of debugging and analysis solution . Also study the the TMS320DM6446 processor Boot-Loader startup process , discusses embedded Linux operating system , compiler , transplant and boot process . Hardware design method for high-speed devices to access large amounts of data the camera hardware board is divided into core board and expansion board . Including core board with 10 Laminates wiring , the wiring of the expansion board with 8 layers . Filter capacitors , isolation beads used in the design of hardware circuit when anti-jamming processing the signal to make the whole system more stable and reliable .
