Abstract


Video surveillance system has good prospects, but the surveillance system in the current market has many deficiencies. The shortcomings of analog video surveillance system is limited to local and short-distance transmission. Also, it has a slow transmission speed and limited storage.Meanwhile, the upgrade is difficult.Although the digital video surveillance system has overcome the above disadvantages, but the wiring is difficult and the cost is high.Traditional wireless video surveillance system has a single network transmission mode, so the network transmission speed is not enough stable.Therefore, the authors designed a new embedded video surveillance terminal system. The system uses the latest video coding standard H.264 to compress data. At the same time, it has multiple network access mode.The embedded video surveillance terminal system has the following features:Hardware system components have S3C6410 processor, 256M memory, 2G NAND FLASH, 130W pixel camera, 802.11b/g USB wireless network card model, 3G and GPRS expansion port and so on.Software system components have bootloader U-boot, embedded Linux operating system, the root file system YAFFS2, the terminal video surveillance software. Software system is the main work . The main contents are as follows:1. Transplant bootloader U-boot. First, the working principle of U-boot is analyzed; followed the structure of U-boot procedure and the preparation process is focus of study; the last U-boot program has been cut according to the needs of the system was ported to ARM platform.2. Ruling embedded Linux operating system. First of all, Linux features and software architecture to be analyzed; Secondly, Linux source code is carefully analyzed; finally, unnecessary features is removed; Linux imperfect parts are added and the compiled program is ported to the corresponding platform.3. Making the file system. First, the role of the file system and file system components are analyzed; followed by the necessary functions of the system is analyzed and the corresponding files are added; the final root file system for embedded systems YAFFS2 be generated through the appropriate production tools.4. Development video monitoring software. Video monitoring software includes video capture procedures, video compression programs and video transmission program. This software realizes the video monitoring terminal system of basic function, achieve the expected effect.The video surveillance terminal system meets the requirements of UAV ground station.video surveillance has been put into test and stable operation. This proves that the development of this method has important reference value to other video surveillance terminal system.
