Com And Storage Area Network Technology-based Highway Toll System Design And Realization

With the social and economic development, expressway in the national economy has not only become the role of services in the industrialization and urbanization, but also the important means in the state economy life to lead the Industrial enterprise to grow and to increase the labor employment. The toll system development in traffic area has a very wide application and will produce huge amount of benefit in society and economy.The toll system was developed with a lot of mature software and hardware technology, it is analyzed and designed according to the method of software engineering.In this paper, the system is divided into several modules, including driveway management, toll management, device management, data management, system management and so on. The SAN technology is used to store image data. According to the characteristic and status of highway toll system, 3-tied technology was used. Comparing with C/S structure, The system total performance is raised up, while system maintenance is simple The main business logic, such as device management is designed as component, so the system will be easy to reuse and extend.The whole development of system follows the software engineering process strictly, including requirement analysis, system design, coding and testing, this ensures the quality and efficiency of development. The system has passed testing and is on use. It shows that the system could satisfy the requirements, and becomes an advanced and reliable information platform of expressway toll system.
