一种新颖的低功耗、强移动性的密码锁设计

本文介绍一种基于单片机控制的电子密码锁设计。本系统由P89LPC900系列单片机、矩阵键盘和报警系统组成。系统能完成电子控制开锁、超时报警、超次锁定、管理员解密和修改用户密码的基本功能。除上述基本的密码锁功能外,还具有节电模式、掉电存储、按键中断唤醒等功能。该系统结构简洁、成本低、体积小,功能实用。

Design of the Novel Low-power and Mobile Coded Lock

This article describes an electronic coded locks based on single-chip microcomputer control.The system consists of P89LPC900 family of microcontrollers,matrix keyboard,and alarm system.The system can complete the electronic control lock,timeout alarm,more than times be locked,administrator decrypt and modify user password.In addition to the basic lock function,but also has a power saving mode,power-down storage,key interrupt wake-up functions.The system is simple structure,low cost,small volume,functional and practical.
