| Video surveillance system is one of computer systems which are based on computer technique, with advanced multi-media technique, net communication technique, digital image technique and others. Along with the approach of Post-PC Age, these techniques all got fast development. As a result, the video surveillance system also turned into a new phase. In addition, the embedded system technique also obtains glorious achievement in last few years. Therefore, this paper gives a video surveillance system designed in embedded system, and this system has some characteristic, such as easy development, short design period.The surveillance system described in this paper is based on S3C2410 and Windows CE 5.0. Voice function is added compared with the traditional surveillance system. This paper discusses the hardware and the migration of embedded Real-time Operation System in detail, including hardware platform, boot loader development, operate system customization and camera driver design.Chapter 1 summarizes the development of the video surveillance system and embedded system, put forward the design contents of this topic.Chapter 2 discusses the selection and realization of hardware in detail. Compared with several scheme, the design based on ARM processor is established. Then the circuit between processor and some devices is given.Chapter 3 analyzes the design of boot loader, it contains Nboot, Eboot, and so on, and then some functions in Eboot are shown in this part.Chapter 4 introduces the cut out of operate system, the buildup of SDK and the development of the camera driver.Chapter 5 gives this system result, generalizes the main contents of this design, and makes an outlook. |
