| 摘 要： | 设计了基于RFID(Radio Frequency Identification)技术的打卡器及射频卡。RFID是一种非接触的自动识别技术,其基本原理是利用射频信号和空间耦合(电感或电磁耦合)或雷达反射的传输特性,实现对被识别物体的自动识别。打卡器基于MF-RC500射频卡读写系统,以STC89C52RC单片机为核心,辅以必要的外围电路,使打卡器能识别射频卡,并对射频卡输出的信号进行采集和输出。该设计的主要创新点是采用STC89C52RC单片机控制,系统稳定性高,价格低廉,编程简单,功耗较低。

| Abstract: | The design is based on the theme RFID （Radio Frequency Identification） technology and RF punch cards. RFID is a non-contact automatic identification technology. The basic principle is it uses radio frequency signal and the spatial coupling （ inductive or electromagnetic coupling） or the transmission characteristics of the radar reflection to realize the automatic identification of objects. Punch card is based on MF - RCS00 RF card reader system with the STC89C52RC microcontroller as the core, supplemented by the necessary peripheral circuits so that punch-card devices can identify the RF card, acquire the output signal of the RF card. The main innovation of this design is STC89C52RC MCU control, system stability, low cost, simple programming, and low power consumption. |
