Wireless Video Surveillance System Based On Linux Platform

Video surveillance in surveillance monitoring is the main way that people have been very concerned about his development,but has also been applied to many industrial and social occasions.As the video surveillance intuitive,the various advantages of convenient and flexible as well as high real-time performance,has become an important means of monitoring.Present article seriously consider the advantages and disadvantages of wireless video surveillance,the design of wireless video surveillance system based on ARM9 and Linux platforms.Use JZ2440 development board to explore and develop a complete system,and research related to key technologies,given the architecture design of the entire software platform,and implemented a series of peripheral circuits and driver design and cutting:First,we completed the hardware design and production,in the build hardware platform,this system JZ2440 core board basis,equipped with peripheral circuits Interface again developed a number of functional modules,such as multi-interface camera module,WiFi interface module etc.,built for embedded software development hardware platform.Secondly,it also completed according to the corresponding hardware module driver development,design preparation and cutting the USB camera driver,serial driver module,WiFi wireless module driver,the driver Ethernet interface.Then complete the development and porting of software systems,including the establishment of a development environment,where the use of the Linux operating system,cross-compiler tool to select the arm-linux tool chain;the development of host configuration,set the serial port parameters,built using the NFS network file system.Construction of Pre-boot program BOOTLOADER,bootloader transplants Depending on the hardware platform of choice.Usually most chips will not boot program built,so we need to prepare ourselves and transplant after the boot program,the system and applications can be programmed into the FLASH above,the complete system can work properly.Finally,based on the software platform,complete development V4L2 video capture program,providing a unified interface to access the upper layer of the video equipment.To achieve the development and porting of video WEB server used for video server that uses the v412 interface.The system is based on the functional modules are divided into transmission module,control several parts module,control modules,etc.and realize the function of each module,and gives specific solutions.Performance embedded development board to achieve the ultimate in remote video monitoring functions,and test out the results meet the project.
