基于51单片机的RFID门禁系统
jacklood的博客
06-14 1252
本设计采用STC89C52作为主控芯片，专用读卡器模块用来读射频卡的信息，当有卡进入到读卡器读卡的范围内时就会读取到相应的卡序列号，并根据得到的卡序列号做出相应的操作。本设计实现了自动、准确的识别卡序列号，对门禁系统起着重要的作用EEPROM采用AT24C04芯片，掉电后可以存储密码，从而保证了系统的安全性。(4)密码输入模块：(a)针对于用按键输入密码，根据密码的正确与否来进行相应的操作；(3)数据处理：针对数据的采集和分析的结果做出相应的处理，例如显示、报警、门控等。

门禁系统需要的器件STC89C52，MFRC-522 RFID射频模块，AT24C02存储电路，5v步进电机，5v转3.3v稳压模块，（1602）12864显示模块， usb接口的5V电源。设计思路采用STC89C52作为主控芯片，MFRC-522模块（5V转3.3模块用于此）用来读射频卡的信息，当有卡进入到读卡器读卡的范围内时就会读取到相应的卡序列号，并根据得到的卡序列号做出相应的操作，或者通过输入密码来进行开门，若正确则开门，若3次不正确则蜂鸣器报警并显示错误信息。

采用LCD12864液晶显示屏实时显示，RC522读卡器实现对门禁卡的感应，当系统检测到门禁卡靠近时获取门禁卡数据并通过LCD12864液晶显示屏实时显示出卡号已经解锁结果等信息，并进行匹配如果匹配成功是注册过的卡的话则控制继电器吸合打开门锁，如果匹配失败不是注册的卡怎控制蜂鸣器led灯发出声光报警提示。同时系统还增加4*4矩阵键盘，用户可以通过键盘进入管理实现注册和删除门禁卡，修改密码等操作，矩阵键盘还能够输入密码实现按键密码解锁。
