Design And Realization Of Software About Expressway Supervision And Control System

The expressway is growing fast in China. It has already formed the network of expressway and has brought about an economic advance greatly. It is an important problem to carry on scientific and effective management to expressway and make it full benefit. The most frequently used and effective method is to control the expressway in real time, we know and grasp present operation situation and state it any time.The expressway supervision and control system is studied in software in this paper. It introduces the development course of the expressway system in detail in terms of software design and realization. In this text, it introduces the basic conception of the system first;the second, it analyzes the system overally;the third, it analyzes and designs the multistage distributed structure, hardware structure and software structure of the system from the framework;the forth, it introduces the design as the most important point in this paper, it contains the division, detailed design, data procedure design and the design of data storehouse;the fifth, it discusses the realization method and something relevant to technology, they are development environment of the system, communication and control the scheme and revealing the scheme of electronic map;Finally, it points out the studying direction, it includes the multidimensional model research in the traffic flow and the research of traffic image recognition technology.
