Highway ETC Toll System Implementation

With the continuous development of society, the highway became a link ties and bridges of the city.The highway toll philosophy in order to meet the growing traffic demand gradually forming. Anhui Province as early as in2009began the ETC lane commissioning work, the the ETC lane toll collection system mushroomed in the past three years in the Yangtze River Delta within the promotion. But the system itself in terms of the technical route, still belongs to the research and development stage, such as:the provincial domain to build the station ETC can not quickly access a lot of issues to be resolved. The charges quickly through behavioral issues, subject to high-speed non-stop research ETC toll system at the same time, the corresponding software billing software developer ETC lane.Topic first st networking from the ETC toll collection system architecture analysis, ETC lane toll system architecture description, from hardware facilities and then to the security of the network architecture design. Focus on the ETC lane toll software development design, use case diagrams, sequence diagrams, data flow diagrams to achieve from a functional to a process on the design from the point of view of the functional requirements. In the software implementation, starting from its related technologies, introduces the software design of the core configuration file and billing software data transmission, electronic capture of the ETC lane, toll management functions for the detailed design and implemented with the code, and then, from the entrance from the system module work processes designed to achieve; then to export work processes designed to achieve, and finally introduce this issue to develop features that realize the function of the entrance information into the provincial domain the build the station ETC export RSU debit, provincial build a station without stopping the speedy passage of the function. Process the end export rsu debit also needed to manually enter the entry information.The issues in the implementation process of the source code to achieve functional test and improve the software’s inheritance; through a design ETC databases distributed architecture, the database at all levels. Simult neously at all levels of their own work. It does not cause loss of data. From the design point of view to the the SQL2005database client based on the establishment of a database, create database tables, views, indexes. Complet the design and the implementation of the database. In order to protect the security of the network charges, the establishment of sub-centers firewalls, switches, charging server, switch, stopping chargeserver hierarchical model. Control port through the firewall and traffic monitoring. Congestion control through the switch. Link toll charges within the network directly to the fiber in the form of a dedicated fiber charge data, pictures and other water uploaded to the network centers of the provincial government. Pvincial build a station CPU card functional testing as the subject, and the form of the test form to record the test content. Care and financial support of the leadership of the subject as has also been the case for government intervention.this will ill be the research and development of the topics included in the trial operation of the road network provincial domain to build station.
