基于STC89C51单片机的电子密码锁设计

Electronic Coded Lock of Greenhouse Based on Single Chip Microcomputer

为解决传统制锁技术无法满足安全防盗、美观简洁等需求这一问题,本文基于STC89C51单片机设计了电子密码锁系统。该系统包括五大模块:主机模块、LCD液晶显示器模块、按键输入模块、掉电储存模块、报警与开锁功能模块。电子密码锁设计好坏可通过密码的输入、清除、开锁、更改等功能所完成的程度作为评判标准。本文设计的电子密码锁具有成本低、安全性高、实用性强等优点,另外对于住宅、办公室等具有强大的适用兼容性。因此,本系统的商业价值高。

Traditional lock technology has been unable to meet the needs of security and theft prevention,beautiful and simple,in order to solve this problem,we based on STC89 C51 MCU design electronic password lock system.The system includes host module,LCD display module,key input module,power off storage module,alarm and lock function module.The standard to judge the design of electronic password lock is the degree of password input,clearance,lock,change and other functions.Electronic code lock unique design,coupled with the lack of other anti-theft tools simple,low cost,high security,practical advantages,in addition to the residential,office for the strong compatibility,so it is very widely promoted commercial value.
