| With the deepening development of China’s reform and development,the number of expressway construction and the actual opening mileage continue to increase,making economic development for the increasing dependence on road traffic.However,while the increase in highway construction,some traffic operators in order to be able to obtain greater economic benefits,in the transport of overload transport.This not only makes the transport vehicles and personnel to bring danger,but also to the highway itself has a serious impact.So the overload management for the highway also caused the attention of the relevant management departments.At present,the dynamic weighing technology of vehicles is an important technology for overweight management of expressway management,and it is also a hot research content which many research institutions and scholars pay attention to at present.The dynamic weighing technology of the vehicle,also known as the highway management department for highway management to carry out overload management effective measures,through the application of dynamic weighing technology,can improve the management of the highway management level,reduce the highway of the maintenance costs of the input.Improve the efficiency of vehicle transport,reduce the vehicle overload caused by the loss of people,cars,roads.This paper studies the construction and data processing of dynamic weighing system of expressway as the research goal,and finds out the shortcomings of the research and the purpose of the research by studying the relevant background and the current situation of domestic and foreign research.And then the actual highway toll station management as the goal,the study of the highway dynamic weighing system design principles,analysis of the composition and basic working principle,the study of the lane layout and work processes and other issues.This paper studies and analyzes the problem of the error source of the dynamic weighing system of the expressway.The design of the load cell and the design of the weighing data and the design of the transmission scheme are carried out,and the research on the anti-jamming design is carried out.Weighing signal wavelet transform and dynamic weighing signal preprocessing method are used to study the radial basis function network model and RBF neural network learning algorithm based on RBF neural network dynamic weighing process,so as to RBF neural network Dynamic weighing technology in the application of the foundation;at the same time carried out the weighing data acquisition,carried out 1RBF neural network in the dynamic weighing algorithm flow,the program and the actual data test,and then get RBF neural network in the dynamic weighing conclusion.Through the above research,RBF neural network algorithm in highway dynamic weighing applications with high accuracy and reliability,its specific application and research has a very good application prospects. |
