1、I 摘摘 要要 现代生活中，很多行业的许多地方都需要密码锁， 密码锁的应用就显得尤为 重要。科学技术的发展，特别是单片机技术和集成电路技术的日臻成熟，为防盗 遥控技术提供了功能齐全、操作方便、工作可靠、成本低廉的系统电路。该设计 的红外遥控密码锁是将红外遥控技术和单片机技术应用相结合的一种方案， 它主 要应用在家庭防盗门系统中。 它的任务是：用户先给密码锁设定一个密码，当外面的人要进门时，就在红 外遥控器键入代码，该密码与用户设定的密码比较，如果密码正确，则驱动电磁 执行器开锁，人可以进门；如果密码不正确，则允许操作人员重新输入密码，最 多可输入三次，若三次都不正确，则单片机通过蜂鸣器给予警告
2、，并自动锁门半 小时，才允许再次输入代码再试。 通过如此严密的检查程序，可以极大地排除陌生人进门的可能性，从而保证 了住户安全。 关键词：关键词：密码锁，红外遥控，单片机，智能控制 II Abstact In the modern life, a lot of places of trade need password lock, the application of password locks seems particularly important.

3、hat the technology of the micro-control unit and integrated circuit technology are ripe day by day, has offered the theft-proof remote control technology with a systematic circuit with such virtues as cheap cost, multiple function, easy operation, etc. It is a kind of scheme of combining technical a
4、pplication of the micro-control unit with infrared remote control technology that the infrared remote control password originally designed is locked, it is mainly applied to the system of burglary-resisting door of the family. Its task is: the homer locks and establishes a password for the password lock first. When the person outside wants to enter the door, he or she must type the code in the micro-control unit, and this password will be compared with the password that the homer has establish
