基于射频识别停车场智能监控系统设计
摘要
停车场智能监控系统设计的应用在市场上已经日趋成熟,而大多数产品只是具备简单的刷卡停车、收费功能,并不能实现车库停车定位的功能。本设计是基于STC89C516RD微控制器和射频识别系统为核心,系统硬件电路包括DC-DC电源电路、ILI9163液晶驱动电路、NRF24L01无线通信电路、USB转串口电路、MFRC522射频电路。系统软件部分是在Keil uVision4编译环境下进行,程序由系统外设和变量初始化构件、射频识别构件、无线通信构件,TFT液晶显示构件组成。车辆定位算法上参考了VIRE和LANDMARC的设计思想。选择了VIRE算法, 在MATLAB平台进行了仿真,辅助完成了基于射频识别停车场智能监控系统的设计, 实现了停车区域车辆实时定位的功能。

The Design of Intelligent Parking lot Management system
based on RFID
ABSTRACT

RFID-based smart parking applications designed monitoring system on the market has matured. The application involves a small number of higher intelligence to the image recognition processing, high research and development costs, plexity. The majority of products are only equipped with a simple swipe parking, charging function, and can’t realize the garage positioning function. The design is based on STC89C516RD microcontroller and radio frequency identification system as the core. System hardware circuit includes DC-DC power supply circuit, ILI9163 LCD driver circuit, NRF24L01 munication circuitry, USB to serial circuit, MFRC522 radio transmitting and receiving circuits. System software under Keil piler environment, the program initiated by the system peripherals and ponents,radiofrequency ponents,ponents, TFT location algorithm refer LANDMARC and VIRE. By analyzing the advantages and disadvantages of the two algorithms, select VIRE algorithm, through MATLAB simulation platform from which to calculate the high positioning accuracy and practical argument, to help achieve real-time location information of parking spaces.
