Design of intelligent parking lot vehicle identification system based on radio frequency technology

摘要

In order to solve the problem of low recognition accuracy and efficiency in traditional vehicle identification system, an intelligent parking lot vehicle identification system based on radio frequency technology is proposed and designed. The hardware structure of the system includes radio frequency identification module, electronic tag module, power module, wireless trigger circuit to complete the vehicle information identification, transmission and system power supply design. The software part of the system calculates the weight of the RFID tag identification results, so as to obtain the horizontal and vertical coordinates of the vehicle and complete the identification of the vehicle position. The experimental results show that the vehicle position recognition results of the designed system are basically consistent with the actual results, and the recognition time is lower than the traditional vehicle recognition system, and the maximum recognition time of the designed system is less than 0.2S. Therefore, it fully shows that the designed system has good practical application performance.
