| Chengya Expressway Chengdu, the main road leading to the northwest, is one ofthe main traffic arteries of the large-scale development of the western region. The entireline in late2000, the construction is completed and opened to traffic. This route or theMinistry of Communications "95" transport infrastructure plans and Sichuan Provincein the Ninth Five-Year Plan entertain within the highway construction project. Facedwith the rapid development of China’s transport undertakings, the increasing amount ofcars on the highway, China’s current manual/semi-manual toll on the highway has beenunable to meet the development needs. And now the way of such a charge in a certainextent there is the problem of imperfect supervision, resulting in very prone to somewrongful act.In this era of growing, computer and communications technology has the rapiddevelopment of software research and development in the transport sector has goodprospects. Because of highway toll should have further developed, along with thedevelopment of network technology and computer manual/semi-manual chargingmethods can not achieve the requirements of the charges towards the development ofhigh efficiency, fast-paced. Order to better promote the development of transport inChina, can not rely on the size of the expansion of the toll station or increase the tolllane to achieve their goals, because this is only an expedient measure, as the economygrows, the traffic flow will drive straight up and, which will also bring the land, andmany other issues. However, if the application of the ETC system of electronic tollcollection, will greatly improve the toll station, and after a series of technicaldevelopment and implementation of laid the foundation. The use of high-performancelane equipment and state-of-the-art computer technology and electronic toll collectionsystem, scientific management methods, to better serve the high-speed public vehicles.The paper first analyzes the toll collection system development at home andabroad, need to study toll collection system. Then introduced the ETC technology anddetailed analysis of the the ETC toll system, followed by comprehensive and systematicintroduction to the most important part of-ETC lane toll collection system. Requirements in all aspects for Chengya highway, I first ETC lane billing software adetailed needs analysis and completed the overall design of the system design anddatabase design, in general terms, Chengya highway toll system is modular design, thedesign of the module system initialization module, service management module the FOcontrol module, serial communication module, database access module and datamanagement module. According to the overall design of the system, I divided for eachmodule, each module of the system detailed design, and the code that implements thefunction of each module. Finally, the entire system functional testing, and gives some ofthe test cases and results analysis, the completion of the entire system development. |
