Design Of Driver Training Time Billing System Based On RFID And Industrial Serial Screen

At present,the driver qualification examination commonly used with the intelligent driving test system which has automatic judging score function.In order to make students familiar with the examation environment,driving school also widely used intelligent driving test system for student daily training.Because the intelligent driving test system only can evaluate the examination.Therefore,it also need to increase authentication and time billing of management functions.Although some domestic manufacturers design the driving school smart billing system to solve these problems.But these systems are separate from the intelligent driving test system,and it need to independly maintenance and debugging.It will increase the costs of driving school and the difficulty of equipment mainteinance.In order to slove above problems,the project has designed a driver training time billing system based on RFID and industrial serial screen,and it could be integrated with intelligent driving test system and it will become a complete product to users.The system uses two-layer structure design,the top layer uses the industrial serial screen as the display terminal,and it provides a friendly and intuitive human-computer interaction interface.As the same time,the FATFS file management system is transplanted and it provides a better document management mechanism of multi-memory of serial screen.The buttom layer uses the STM32F429 which based on the Cortex M4 for the core processor to improve the response speed of system.The RFID radio frequency identification module which based on MF RC522 is used for acquiring the information of student identity and consumption.WM-G-MR-09 WIFI Wireless network module and WK2124 serial port expansion module is provides the data interface to the driving school management terminator and intelligent driving test system.The RFID anti-collision algorithm which involved in the project is discussed in detail and made appropriate improvement above the basis of the original theory.The simulation results show that the improved anti-collision algorithm could reduces the transmission byte overhead,and it also could increase the transmission efficiency of the system.In summary,the human-computer interactive experience of driver training time billing system based on RFID and industrial serial screen has some appropriate improvement.It has a comfortable touch experience and better picture display.The project also reducing the byte redundancy of RFID anti-collision detected process.The multi-interface design to help driving school centralized management of information.Therefore,the project of driver training time billing system based on RFID and industrial serial screen is reasonable and feasible.It also has strong practical value and certain theoretical significance.
