一、设计任务与功能要求
门禁电子密码锁程序设计
通过小型微机应用产品的设计与调试过程,运用《微机原理及接口技术》课程所学的基本知识,在设计中加以应用,进而得到理解、巩固和提高发展,通过实践的过程学****掌握分析与解决实际问题的方法与手段,提高设计、编程与调试的实际动手能力,作为工程技术工作的一次基本训练。
设计一个以单片机为核心的门禁密码锁。具有密码***,不同权限的密码修改、密码输入安全设置、开门时段管理等功能。编程并在单片机实验板上模拟调试实现。
1、开机进行接口部件及数码显示器、指示灯、讯响器等自检。
2、密码分为管理员密码和用户密码:管理员密码为8位0~9的数字,而用户密码为6位0~9的数字。
3、设置“0”~“9”的数字键及“ESC”和“ENT”等功能键。对按键输入信号须进行软件消抖处理。
4、工作模式:
(1)常态:数码管显示时钟。
(2)***模式:需输入6位数字为0~9的密码进行***。密码数字可以由管理员事先设置保存共普通用户使用。
(3)管理员操作模式:需输入8位0~9的密码,可以进行修改用户密码、修改管理员密码、修改进门时段等功能。
5、常态下,八位LED 7段数码管显示时钟信息可包括小时、分钟、秒钟。
6、只要按下0~9的数字键则转入***
