Design and Implement Circuit of Wireless Charging of Parking Management System

Abstract

This paper presents a designing and implementing circuit of wireless charging of the parking management system based on Radio frequency identification (RFID) technique and STM32F103 as the control kernel. The advantage of digital modulation technique in applied radio signals is used to identify specific targets and read-write relevant data. Communication is established between the parking space reader and the onboard responder. Parking time and power consumption collected by a peripheral circuit of STM32F103 are connected to a computer through means of the modulation technique of digital frequency modulation FSK with data duplex communication. The host computer processes the received owners’ parking data and shows the results on the terminal display screen. The cost of charging power and parking time is settled automatically by a remote payment system through the network interface using protocols like TCP/IP. Moreover, if some abnormal conditions occur, the host computer can initiate a sound-light alarm automatically to notify field staff. The tested new circuit design shows that the proposed scheme is a practical tool.
