具有定时报警功能电子密码锁的设计

Design of Electronic Cipher Lock with Timing Alarm Function

近年来随着科技的飞速发展,报警器的应用正在不断地走向深入,因此一种廉价、性能灵敏可靠的防盗报警器必须在防盗和保证财产安全方面发挥更有效的作用,针对目前的实用需要,设计具有定时报警功能的电子密码来实现开锁。密码锁是锁的一种,开启时用的是一系列的数字或符号,密码锁的密码通常都只是排列而非真正的组合。部分密码锁只使用一个转盘,把锁内的数个碟片或凸轮转动;亦有些密码锁是转动一组数个刻有数字的拨轮圈,直接带动锁内部的机械。如果没有获取正确密码而进行误密码输入,将启动报警器报警,实现了密码锁和报警器的结合。

In recent years, with the rapid development of science and technology, the application of alarm is constantly deepen- ing, so a cheap, sensitive and reliable performance of the anti-theft alarm must property security to play a more effective role in security and the guarantee, in order to meet the needs of the practical design with timing alarm function electronic password to unlock. Password lock is a lock, open with a series of numbers or symbols, password lock password is usually only arranged rather than a combination of real. Password lock using only a turntable, the lock in the number of discs or rotation of the cam; al- so some password lock is a set number of engraved with the digital dial wheel rotation, direct drive machinery inside the lock. If the correct password is not obtained, the alarm is started, and the combination of the cipher lock and the alarm is realized.
