Design And Implementation Of Network Video Surveillance System Based On BF533

The traditional video surveillance systems have the disadvantages that their costs are high and need dedicated lines.It can't connect to the network and need a mass of storage medium.With the video processing and network technology becoming more and more sophisticated,the network video surveillance system has been increasingly applied to our life.It allows people to access to the environmental condition of the monitored point,and to make the right decisions.A BF533-based embedded network video surveillance system is designed and implemented with features of low-cost,flexible installation,function-rich.The advantages and disadvantages of three different solutions of the network video surveillance system paper are analyzed.It considers such factors as the cost,the development difficulty,and so on.Ultimately the BF533 embedded DSP processor is selected as the basis of the system platform architecture.The peripheral chips and system softwares are selected on that basis.The hardware modules including BF533 processor,SDRAM,FLASH, video decoder,video encoder,audio codec,ethernet controller,RS232 driver/receiver,CPLD and power are designed in detail.Before porting U-BOOT to a specific board,it should understand the source code.The U-BOOT source code is analyzed in-depth according to the startup flow of U-BOOT.The dirvers of DM9000AE and SST39VF1601 are programmed.The concrete step of porting U-BOOT is described.It should be tested whether the system hardware works properly. The test method of each module is discussed.The test code is written. The test result is given.The procedure of compiling U-BOOT is shown. The setup of loadingμClinux from network is explained.
