Description: 数字密码锁设计 基本要求：
（1）开锁密码为四位十进制数。（2）按任意一个键后，系统进入等待状态，显示0000，此时若按密码输入键就将此刻外接四位输入数据线线上的一个十进制数字读入，将先前输入的数据左移一位，最末位加入刚输入的数据后显示，读入数字超过4个时，只保留最近输入的四个数；若按一下删除键可以消除刚输入的数字，数据右移一位，高位补0。若按确认键，将读入的4位数字与系统密码比较，正确的话开锁，数码管都显示“P”，不正确就显示“E”,拒绝开锁。（3）连续尝试3次没有能开锁进入死锁状态，拒绝接受输入，同时发出报警信号，显示“F”。3分钟后停止报警，又恢复到正常待机状态，可以重新接受密码输入。-Digital lock design basic requirements:
(1) unlock password is four decimal numbers. (2) Press any key, the system enters a wait state, 0000, at this time if the password input by four key will now add a line of input data line read decimal numbers, the left one previously entered data bit, just add the last bit of input data display, digital read more than 4, only keep the last four the number of inputs When you click the Delete button to remove the number you just entered, the data shifted to the right one, high up 0. If you press the Enter key to read the 4-digit password with the system compared to the right, then unlock, LED show "P", is not correct to show "E", refused to unlock. (3) three consecutive attempts failed to lock into a deadlock state, refused to accept the input, an alarm signal that the "F". 3 minutes to stop the alarm, has returned to normal standby mode, you can re-accept the password.
