Traffic Monitoring System Research Based On Embedded Linux

Network Digital Video Surveillance System is a combination of multiple technologies integrated systems, including digital video technology, network communications technology, computer technology and software engineering. When applied video surveillance to traffic management, providing intuitive and rich information content for the busy, complex traffic management has brought convenience. The network, and digital transformation of the video surveillance system is to further broaden the areas of traffic management, and has accelerated the flow of information so that the traffic management system known as the services are widely, powerful information network.Able to do digital video data in real-time transmission and control network benefited from the progress of video technology, network technology and the improvement of the rapid development of embedded technology. The embedded network video monitoring system with the traditional video surveillance systems, not only the stability of real-time processing speed, functionality, price, scalability, and so has a prominent advantages, but also in the field of research and development direction.After the survey of the development of traffic management, this paper against the limitations of existing systems and disadvantages, using new technology development results, made the following research of traffic control system based on embedded Linux.1,System overall structure and framework for the design methods have been proposed. System design fully taken into account the stability, reliability, scalability, and the construction of the project and maintenance costs. Through digital transformation so that the new system and the old system integrated into the overall function of perfect and strong, Through the Internet and browser technology so that traffic information dissemination and access to a more flexible manner, the broader scope. For better management of the increasingly large urban traffic network, clear the induction of the traffic congestion, deal with traffic emergencies we provide a complete system solutions2,Implementing hardware platform design of the embedded part。The system hardware platform to S3C2410A as the core, use of such as the CS8900A cost-effective networking chips, SDRAM, FLASH. Through various interface connector from the camera, and other peripheral equipment detection coil formed a fully functional hardware system.3,On the basis of analyzing the characteristics of Linux and development of embedded, established cross compiler environment based on the goal platform. To streamline and optimize the operating system, re-cut and compiler of the Linux kernel. This core only to provide the necessary functions of system. According System features select and edit the file system.4,Programming USB camera drive design with the core of Linux. Application software in the design of a Linux take full advantage of the multi-process and multi-threaded features designed to simplify rocedures, multi-process to achieve a number of concurrency control, Multi-thread network communication procedures enhance network efficiency, reduce system costs. Next traffic control algorithm using fuzzy theory.This thesis proposes results has been applied to the second phase project of digital video in science and technology projects of the Beijing Public Security Bureau Public Security Traffic Authority. After a period of testing and perfecting the system stable and reliable operation and has shown good results.
