Highway Full Of Video Surveillance Mode And Technology Research

The present operation method and management mode cannot meet the reqirement of the fast developing modem traffic. What management method to be adopted has become a new project. As the foundation of modem traffic, expressway with its obvious characteristic of great transportatin capacity and high driving speed, becomes the key transportation method and important transportation access. And the construction of mechanical and electrical system is the foundation for modernizing the management of expressway. This article aim to the monitor style and technique method of whole section of a highway. First, the management process of expressway is analyzed. The function and technique situation of the communication, monitor and charge system of the expressway?s mechanical and electrical system is detailed described. Secondly, the technology used in wide area network is analyzed and compared. Thirdly, the information type and transmission mode of the expressway?s WAN. Forthly, a new techique model is presented for the whole video/audio monitor system of expressway network.Finally, the achieve summarize the harvest in practice caused by the new mode and also expect technique develop direction in the future.
