[SCM] JJJ DL : 0: 电子密码锁用4×4组成0－9数字键及确认键。用8位数码管组成显示电路提示信息，当输入密码时，只显示“8.”，当密码位数输入完毕按下确认键时，对输入的密码与设定的密码进行比较，若密码正确，则门开，此处用LED发光二极管亮一秒钟做为提示，同时发出“叮咚”声；若密码不正确，禁止按键输入3秒，同时发出“嘀、嘀”报警声；若在3秒之内仍有按键按下，则禁止按键输入3秒被重新禁止。（此句在下面程序中需要再按下ENTER键方有效）（1）． 4×4行列式键盘识别技术：有关这方面内容前面已经讨论过，这里不再重复。（2）． 8位数码显示，初始化时，显示“P　　　”，接着输入最大6位数的密码，当密码输入完后，按下确认键，进行密码比较，然后给出相应的信息。在输入密码过程中，显示器只显示“8.”。当数字输入超过6个时，给出报警信息。在密码输入过程中，若输入错误，可以利用“DEL”键删除刚才输入的错误的数字。（3）． 4×4行列式键盘的按键功能分布图密码为12345 可改本仿真已通过做板得出-Electronic combination lock composed with 4 x 4 0-9 keys and confirmation button. Composed with eight digital tube tooltip show circuit, when the input password, only show "8." when the password digits input finished press ok button, the input password with setting the password, if correct password comparison, the door open, here use LED leds light a second as clew, also issued "mistakes" sound If the password is not correct, banned keystroke 3 seconds, also issued "di, di" alarm sound If in 3 seconds still have keys pressed, bans keystroke 3 seconds to be banned.
