摘要
采用ARM7的LPC2132微处理器作为主控制芯片,结合电源、存储芯片、直流电机及蜂鸣器电路设计,给出了实用型电子密码锁的软硬件实现方法,系统具有以下功能:输入修改添加,正确开锁,连续错误3次报警,输入超时恢复初始化状态.另外,本系统把触摸屏技术和密码锁技术有效地结合在一起,利用ARM7片上资源丰富、处理速率快,触摸屏效果直观、使用方便等特点来实现整个系统的功能.
The paper presents a design of electronic cipher lock based on touch screen,which takes microprocessor LPC2132 of ARM7 as the core component to control the entire system. The paper makes detailed description about the design principle both of hardware and software. The system has some functions ： password input, add, clear and display, when password is correct the system is unlock. Alarm when entering wrong password over three times, lock the keyboard and set the initial system when the input password is wrong or the input time is over. This design reduces the fault rate and improves the reliability,security and safety. Combined with touch screen,the electronic cipher lock works effectively and conveniently.
