1、单片机技术及应用综合训练（设计报告)前言随着人们生活水平得提高，如何实现家庭防盗这一问题也变得尤为突出。在科学技术不断发展得今天，电子密码防盗锁作为防盗卫士得作用显得日趋重要。本文从经济实用得角度出发,系统由 ST9C与低功耗 CMOS 型 E2 PRO T24C02 作为主控芯片与数据存储器单元，结合外围得键盘输入、CD 显示、报警、开锁等电路模块。它能完成以下功能:正确输入密码前提下,开锁；错误输入密码情况下，报警;密码可以根据用户需要更改。用C 语言编写得主控芯片控制程序与EEPROM AT24C2 读写程序相结合，并用Kel 软件进行编译,设计了一款可以多次更改密码，具有报警功能得电子

2、密码控制系统。本密码锁具有设计方法合理,简单易行,成本低，安全实用,保密性强,灵活性高等特点，具有一定得推广价值。关键词:电子密码锁、报警、液晶显示文档编码:CU4B2W4T1K7 HH3K4S2Q6O7 ZQ5C1Z10S9K10文档编码:CU4B2W4T1K7 HH3K4S2Q6O7 ZQ5C1Z10S9K10文档编码:CU4B2W4T1K7 HH3K4S2Q6O7 ZQ5C1Z10S9K10文档编码:CU4B2W4T1K7 HH3K4S2Q6O7 ZQ5C1Z10S9K10文档编码:CU4B2W4T1K7 HH3K4S2Q6O7 ZQ5C1Z10S9K10文档编码:CU4B2W4T1K7

17、好，编码量多,远远大于弹子锁。随机开锁成功率几乎为零.2)密码可变,用户可以随时更改密码，防止密码被盗,同时也可以避免因人员得更替而使锁得密级下降.?3)误码输入保护,当输入密码多次错误时,报警系统自动启动。4)无活动零件，不会磨损，寿命长。)使用灵活性好，不像机械锁必须佩带钥匙才能开锁。6）电子密码锁操作简单易行,一学即会。二、硬件电路设计下面就是整个设计得流程图：、1 5 单片机开开初始化次数加 1 输入密码密码正确？返返回回N Y Y 开锁程序开锁？N 修改密码？次数 3？报警程序修改程序Y N N Y 开始返回文档编码:CU4B2W4T1K7 HH3K4S2Q6O7 ZQ5C1Z10S
