B48 - 基于51单片机的学生管理门禁系统设计
任务
设计要求和参数
1. 设计要求：
（1） 能够根据RFID和指纹对学生的身份进行识别（识别成功显示所在院系、班级、专业、学号等）；
（2） 能够利用矩阵按键输入管理员密码后添加新的指纹认证信息。
（3） 具有学籍状况查询功能：考勤查询、进出校园记录、操行记录及安全追踪等功能。
（4） 能利用按键查询信息，并在LCD上显示。
2. 设计参数：
（1） RFID：工作频率：13.56MHz；通信速率：106Kbps；读写距离：≤10cm；传递数据时间小于200ms；
（2） 指纹模块：工作电压：3.3V；分辨率：500dpi；录入时间：0.1S；可录入指纹数：300；
（3） 系统电源5V，具备电压转换功能，提供3.3V电源输出接口。
（4） 主控单片机：工作电压5V，采用STC（宏晶）公司新型的8051单片机。设计架构：
本系统的设计包括了研发系统的软件和硬件设计两方面。其中系统硬件主要包括：STC8A单片机、无线射频频RFID识别模块、指纹识别模块、薄膜矩阵按键模块、LCD液晶显示模块、时钟模块、电源模块和报警模块，通过对各模块的学习设计和连接最终开发出硬件电路总系统。软件设计则是首先对每一个注册的RFID卡进行编码和匹配学生信息，当有RFID卡靠近系统硬件的RFID识别模块时，系统会读取ID卡号，并且对传递过来的ID序列号与原有注册并存储的ID序列号进行对比来核对卡号是否正确，如果ID信息匹配成功，则LCD显示屏就会出现该ID对应的学生的信息，同时绿灯也会变亮，门禁打开，但是一旦ID匹配失败，则LED就会变成红灯亮，同时蜂鸣器也会发出错误警报声音，若识别错误连续次数达到3次，则会导致系统锁定1分钟（为了便于演示，本系统暂设为15S），锁定期间蜂鸣器一直响，红灯一直亮，用于警示识别错误无效ID人员来避免该人员闯入。指纹识别和提示、报警灯于RFID流程基本一致。

系统上电界面逻辑
本系统设置了多个界面逻辑，有正常检测界面、管理员身份登录界面、指纹添加界面、指纹删除界面、历史信息查看界面等。系统的界面设置有一定的直观性、提示性能够方便使用者快速知道当前界面是干什么的且能够根据提示知道如何操作等。本系统上电后会首先显示设计人的信息，3秒延时后进行指纹模块的检测，当检测到指纹模块后进入到指纹模块的检测，当检测指纹模块正常时会显示加载成功并进入到EEPROM检测读写界面，因本系统需要存储学生的门禁出入信息，故而进行新旧单片机的判断，如果是系统首次上电即单片机是新的则将EEPROM进行格式化，并设置标志位写入来方便下次判定单片机是经过存储的。在下次上电的时候以便能够读出存储的学生信息。界面显示2秒后则进入到正常的检测界面。
系统管理界面逻辑
本系统在正常检测界面可以通过薄膜矩阵键盘的A键进入后台管理界面，在此界面下需要输入管理员密码，默认密码输入下是 * 号进行隐藏，也可以选择按下薄膜矩阵键盘的 * 键选择明码。当输入管理员密码正确后可以进入到后台进行指纹的添加、删除操作，也可以进入查阅界面进入历史数据查询等。
指纹功能界面逻辑
添加指纹：
当系统输入密码成功进入管理界面后台后，可以选择按下薄膜按键的A键进入系统的指纹更新界面，在此界面下可以选择添加指纹、删除指纹、搜索指纹、返回上级选项。本次通过按下薄膜按键的A键进入添加指纹选型，通过屏幕提示按下薄膜按键相应的按键进行ID号的更改、确认、返回等操作，在确定ID号后进入到添加指纹界面进行指纹的录入，经过两次采集手指图像进行存储。添加指纹的功能界面设计如图5.6所示，实物调试如图5.7所示。
删除指纹
本系统通过按键的选择进入到指纹删除界面，在此功能下，通过确定可以选择删除存储内的所有指纹信息，删除完成后自动返回到指纹功能总界面。本次设计的界面和实物调试如图5.8所示。
搜索指纹界面
本系统当添加完指纹后，可以通过搜索指纹功能进行测试，来确保指纹添加成功，当在搜索指纹时，如果搜索成功则返回指纹ID，识别则LCD显示对应的提示。如图5.9所示为指纹搜索界面设计，图5.10所示为实物调试界面。
历史数据查询界面逻辑
本系统能够查询历史的门禁出入记录。在管理界面通过选择B键进入查阅记录界面，在该界面下通过B、C键可更改查阅的人员，按下D键进入对应人员的查阅界面，如查阅李四的进出记录。在查阅界面下通过B、C键进行查阅记录的翻页操作，总共记录了9页历史出入信息，每页记录两次。本系统的查阅界面设计如图5.11所示，实物调试效果如图5.12所示。
指纹和RFID门禁系统解锁测试
如图5.13所示为正常检测界面，在此界面下，可以通过指纹或者RFID进行门禁系统的解锁，如果指纹检测ID匹配学生信息成功或者RFID读到学生ID卡且该卡存在于数据库中则系统会进行门禁解锁，同时LCD屏幕显示解锁学生的信息，5秒后系统LCD屏幕返回正常检测界面信息显示。若解锁失败则系统会提示相应信息，若超过3次解锁失败则系统进入长报警界面。如图5.14所示为指纹解锁成功，如图5.15为RFID解锁成功，如图5.16所示为指纹解锁失败，如图5.17为RFID解锁失败，如图5.18为多次解锁失败系统锁定。
本系统的各个界面的设计相对复杂了许多，本系统要设计多个界面，需要在各个界面之间相互跳转，且在各个界面下矩阵按键的各个键都有不同的使用功能，故本次着重介绍了实物调试过程中进行界面的设计、划分和跳转。
