随着学生的数量不断增长,校园的安全成了社会化问题,普通的签字式巡检方式,可靠性差,效率低,真实性不足,管理者不容易准确掌握巡检人员的工作状况。本文介绍的基于RFID技术的智能校园安全巡检系统。本系统以ATmega16单片机为平台,采用DS1302作为实时时钟,通过MF522芯片驱动13.56MHz天线,对S50信息纽进行读取,并通过EEPROM保存读取信息和时间,以串口通信的方式,将数据上传给PC机。整个系统可靠、高效、真实、便于管理监督。
With the increasing number of students, the safety of the campus has become a social problem. The ordinary signature inspection method has poor reliability, low efficiency and lack of authenticity. It is not easy for the managers to accurately grasp the working conditions of the inspectors. This article describes the RFID-based intelligent campus security inspection system. The system uses ATmega16 microcontroller as a platform, using DS1302 as a real-time clock, through the MF522 chip driver 13.56MHz antenna, the S50 New Zealand to read and save information through the EEPROM to read and time to serial communication way to upload data to PC machine. The entire system is reliable, efficient and real, easy to manage and supervise.
