Cache And Network Transmission Of Traffic Information Video Capture Card To Achieve

With the development of society and economy, the traffic system became becomes more and more complex. In the interest of providing the management of traffic system with real-time traffic information to achieve efficient management and make full use of the traffic systemmanage the traffic system efficiently and make full us of it, we investigate the second generation of Traffic Information Analysis System based on the first generation of Traffic System.Our system consists of four parts, including the Image Sensor Module, Image Compression and Storage Module, Network Transmission Module, and Image Processing Module. This articlethesis will concentratefocuses on the design and implementation of the Network Transmission Module and Image Storage Module.This article thesis firstly introduces the development background and basic definition concept of the Intelligent Traffic System, also the development of Traffic Information Collection System and the advancement advantages of the systems based on viewvisual information. The second part of this article introduces the task and overall design of our project, and the parts I have investigatemy work in this project. The third part introduces the design and implementation of the network Network transmission Transmission moduleModule, including the configuration and drivers for chip LPC2214 and LAN9115, also the network protocol used in Network Transmission Module and how t o its implementation. The forth part introducetalks about the implementation of the image Image storage Storage moduleModule, including the SDRAM's theory and architecture and theoryof Synchronous Dynamic Random Access Memory (SDRAM), how to implement the controlling ofthe implementation of SDRAM read-write controllor, and the emulation results. The fifth part introduces the design of the image Image processing Processing moduleModule. At last the sum-up gives the key-point and direction ofthe continuing future work.
