Design And Implementation Based On Expressway Compound Of Electronic Toll Collection System

The goal of Expressway development in our country is stepping into the modernization from its construction. Along with the expressway road network gradual formation, "Building roads with the loan, Repaying the loan with the charge " has been the main construction pattern of expressway, The most important question that expressway transportation is facing is that the information transmitting and the data exchanges proposes the new request. Most of change pass through take independently invests the main body separately to charge the expressway toll mutually as the unit the charge pattern, the generation by the entire road network scope in networking charge, some many essential technical question urgently requires to be solved. In recent years, our country various provinces expressway construction department all started to prepare and to set up in the province territory the networking charge system . The charge process levies a series of operations including the toll, involves the vehicle type classification, the toll computation, the payment method and whether stops and so on the factor. At the same time, construction toll station investment very big, goes needs on the expressway vehicles to stop many times on the main road pays expenses, to create the Traffic congestion, therefore uses the networking charge, then the realization charge system "a card can go though all road" the project is extremely essential . As the modern transportation important constituent, the ETC technology is included in the high technology and new technology industrial production key domain scientific research topic which in 2006 Yunnan Province gives priority to development.This article main aims at the networking charge the charge way, the service pattern, the financial clear classification question conducts the research. The discussion fits the present Yunnan Province networking charge the solution, take the Yunnan Province three big highways management company the technical plan which ferments in the mechanical and electrical project networking charge as the basis, introduced the Yunnan Province highway networking charge topic produces the background, proposed the combination networking charge thought, from the system constitution introduced the combination networking charge system four network architecture and the networking charge software basic function, research structure satisfies the networking charge to have powerful computer network system carries on the charge account service to analyze criticizes with the data exchange, the financial divided classification design reliability and effectiveness, direct influence entire networking charge system investment and effectment. The financial divided classification "fair", "public" is the networking charge core.This article main content includes:1. Analysis domestic highways management present situation, puts forward the networking charge concept and search necessity.2. Description networks system charge way, the service pattern, the medium choice as well as choice staffs, harness while the staffs corrupt practices the question.3. Summary networks system constitutes four layer network constructions, propose the accounts settlement center network architecture, The financial divided classification, software foundation service software basic function.4. Description networks collect fees the clear subsystem software design and the realization, The method and each kind of clear minute situation have conducted the research, proposed settles divides the principle.5. Finally carries on the forecast after the paper summary and the topic investment production effect.
