Design of Self-service Intelligent Parking Management System based on WSN

With the increasing utilization of parking lot, the demand for intelligent parking management system is higher and higher. Through the realization of intelligent and networked management, it is the ultimate goal of the parking lot management system to be able to book and check the parking spaces of multiple parking lots, and finally realize the scheme of stopping whenever you want. The design is an self-service intelligent parking management system based on wireless sensor network (WSN for short). The upper computer compiles the upper computer management system through C #, monitors the data from the lower computer ZigBee in real time, and receives the vehicle information data from the terminal node through ZigBee wireless way. ZigBee module is mainly based on STM32 single chip microcomputer, with ZigBee module as ZigBee node. The system consists of coordinator node and terminal node. The terminal node is equipped with infrared sensor to monitor whether the vehicle is parked or not, which realizes the intelligent management and accurate use of the parking lot. The experimental test results show that the system has a short response time and high response accuracy. The average positioning time of parking space is about 2s and the average positioning accuracy is no more than 5cm.
