If use RFID in car management, what will it be? How is the prospect for development? The current situation of expressway toll collection system 1. The traffic speed problems With the rapid increase in the amount of cars, in some important sections of an expressway, the toll rate directly influence the traffic speed. Artificial charge costs a lot of time and when large traffic flows, it will cause a traffic jam, which may even cause a traffic accident. Improve the efficiency of toll station has become a problem that people increasingly concerned about. 2. Labor management problems Today most of the work in expressway toll collection system is manual work. However, labor management is a heavy work and may cause some mistakes. In some busy section, there are many cars passing through all day, which leads to a very heavy work. Besides, there may also exist some mistakes in their work, such as receiving fake money, counting the wrong price and so on. In some situation the toll collector
may take the money into their own pocket. Expressway automatic toll collection system using RFID 1.The units in expressway automatic toll collection system The expressway automatic toll collection system comprises:a data acquisition unit,the management of traffic lanes,lane control machines and settlement network interface unit,owner-managed unit and checking system unit. Simply speaking,a vehicle enters the automatic toll signal region,the RF card will produce a pulse induction signal to start the RF system to transmit the vehicle data through the network to toll sub-centers;the toll sub-center will determine the data,which is gathered,is egitimate or not,then it will sent the calculated results through the network to toll management center;the toll management center will get the results by using the transmitted data and with the reference history information of the data,then it will sent the results to the toll station inverse;toll station will make the corresponding action based on the results. 2.The key technology in expressway automatic toll collection system 1)The recognition of moving vehicles:RF vehicle identification system can identify a long distance and a fast speed.Vehicle can be identified in a short time. Vehicle identification system is composed by the car radio cards and reading devices. RF technology is non-contact means of communication.RF card reader and RF card collect data through wireless communication and identify the characteristics of the carriers. 2)Data transmission:To ensure data transmission system's secure is the key to long-term work.Since the transmission of data of RF technology requires only a fraction of a second,the time period can be used is very short.Besides since it is microwave radiation and has a low frequency,the probability of being stolen is low. This ensures that the security of the data collection phase.In the process of the data sending to the center,the transmission line is used,it ensures data transmission security

3)Database Management:Database management system is the center of the system function.It includes the main two parts:the toll collection system data management unit and bank data management unit.Data management for toll collection system commit vehicle-related data collection,the computing of cost, system security management and so on;banking data management complete the toll services.Users can save money to the carrier,and when the system can withheld from the account in the process of highway driving.Of course,credit card can be used, achieve a highway spending before repayment. 3.The process of expressway automatic toll collection system The process of using RFID system to achieve non-stop expressway automatic toll collection system is as follows: (1)Installed the trigger coil means near the charge port.When the vehicle enters the signal region it will trigger the coil means,then the antenna of the reader starts to work. (2)The antenna and RF card in the vehicle communicate with each other,so the reader can get the car's encoding information.Then the information will be transmitted to the backend host system for processing. (3)The host system first determines whether the target vehicle's coded information is valid.If valid,the system will automatically deduct tolls inside the corresponding account,then the system will inform the driver of whether this charging is complete through the light or buzzer and automatically rise the interdiction railing to allow vehicles to pass.If the encoded information is invalid or the account has fee shortage,the system will close the way. (4)When the vehicle complete the payment and pass the a drop-shot coil device, the interdiction railing will automatically fall and the traffic lights turn red; (5)Finally,the system will save the payment transaction records,upload the information to the toll station server,and then continue to wait for the next target car. 4.The superiority of expressway automatic toll collection system 1)High reliability of information:Since the time period in the transmission of
