摘　　要：针对高校内有学生丢失校园卡后,由于信息不畅通,经常会出现当被通知到领取丢失的卡片时,该学生已经重新补办校园卡的现象,设计了一种自动回收校园卡的装置。该装置能够利用射频识别模块对校园卡进行识别,并能通过GPRS模块短信通知到丢失校园卡的同学或老师。本装置以STM32单片机为核心控制器,辅以外围设备电机,光电传感器,按键模块等,也能够实现丢卡者自动认领丢失校园卡的功能。通过对整个系统研究发现,该装置具有安装方便、成本低、高效、简易等特点。For college students who lose their campus cards,information is not smooth.Cards often appear while the student has rebuilt the phenomenon of campus cards.Then an automatic recovery device for campus cards is designed.The device can use the RFID module to identify the campus card and can notify the students or teachers who have lost the campus card through the GPRS module.The device takes STM32 microcontroller as the core controller,with peripherals,motors,photoelectric sensors,key modules,and so on.It also enables the card reader to get the losing campus cards.Through the study of the whole system,it is found that the device has the advantages of convenient installation,low cost,high efficiency and simplicity.
