电路描述:

安全是我们日常的生活中最关心的问题。 每个人都觉得安全问题是非常至关重要的,在家里的门和安全,可以尽可能多的安全。 为了对于门访问安全

因此,我们打算通过引进一个电子密码锁系统,该系统包括一个人得到一个访问某些项目之前要输入密码的安全性,以及在家里,一个房间密码锁系统,不只是普通的单用户密码锁系统,需要用户插入已编程的代码来访问一个房间; 它是一个密码锁系统,有密码而且可以启用多个用户访问。

在基于51单片机的门储物柜,只允许授权人员进入限制区域的门禁系统。 该系统由8位微控制器AT89C2051具有ROM的2K字节的程序存储器完全控制。 该系统具有通过该密码,可以通过它来输入键盘。 当输入的密码与存储在存储器中的口令相等则门被打开。 如果我们输入了错误的密码超过三次,然后报警接通。

LCD的数据引脚连接到P1口和RS,R / W,E引脚连接到P0.2,P0.3,P0.4。 L293D采用旋转电机打开和关闭更衣室。 A 4 * 3键盘用于输入数字0到9,“*”,“#”。 有一个系统菜单,包含了开放式储物柜三个按钮,重设密码,并关闭了更衣室。
