Design Of ETC Lane Software System Based On DSRC Device

In recent years, with the rapid development of China’s logistics, tourism and other industries, has brought with increasingly more serious traffic pressure. Today, private car ownership in China reached one hundred million units, is about 15 times ten years ago. People are constantly strengthen the travel demand, puts forward new requirements for highway traffic rate, the traditional MTC charges in traffic congestion caused by the toll station need to change. Our Countries adapt to the development trend of intelligent transportation, ETC as the vanguard of ITS research field in China. The purpose of this paper is to design a software applied to ETC lane On the basis of Our country ETC technology program.Firstly, this thesis made a brief statement to the technical background of ETC road toll system which used 5.8G band RFID technology. Described the importance of ETC in the country to build smart cities, reduce environmental pollution, improve the overall service level of the process brings. Analyzed the information exchange process computer, RSU and OBU the three devices, which used DSRC protocol standards in China of highway toll station. But also analyzed and compared the communication interface programs between computers and RSU, lane layout scheme.Then made a detailed research to the working principle and hardware configuration and the role of hardware in the ETC lane subsystem, cleared the main functions of ETC lane subsystem, completed functional and performance requirements analysis in the lane subsystem software. On this basis, design and implementation of the lane system software framework and database, it laid the foundation for the realization of the system.Completed each module development based on the overall design of the system. The software has the following characteristics: 1. the lane system software with automatic work function, after the system initialization is complete the system will automatically enter the work, the operator enters the operator to work after landing mode to facilitate the rapid switching operators work and commuting. 2. While having enclosed ETC lane exit and entrance fee logical business processes, implementation of export or import function according to the entrance configuration. 3. abandoned the hardware implementations which using VDM for text information on the capture images superimposed, the use of software for text information superimposed on the image features and cost savings. 4. Improved toll mode cycle regularly read transaction flow recorded in the toll lane, use messaging middleware enables real-time upload transaction flow recorded, while the use of open source components, system stability is further guaranteed.Finally, using the laboratory-developed DSRC equipment to build a test platform, each function with lane software has carried on the detailed test.
