基于单片机的多功能电子防盗锁的设计

Design of Multifunctional Electronic Anti-theft Lock Based on SCM

目前机械锁普遍存在的设计形式和功能单一,且钥匙容易复制、丢失的问题.而常用的电子防盗锁多采用固定的密码,存在信息易被偷窥或偷拍,老人儿童经常会出现忘记密码的情况.针对以上不足,提出一种基于单片机的电子防盗锁设计,采用按键解锁和指纹解锁相结合的方式,同时能够实现密码可变,误码保护,信息提示等功能,具有了更高的安全性和易用性.

There exist some problems in the present design for the mechanical lock,such as,simple form, poly function,and easily - copied and lost key,while the most commonly - used anti - theft lock only has certain passwords,still having some shortcomings like easily being peeped or videotaped,and most often,the old people and the children forgot the passwords. The design for a new electronic anti - theft lock,taking the above short-comings into consideration,was given in this paper,which adopts the combination of buttons and fingerprints for unlocking,and also realizes its multifunction of variable passwords,error protection,and information cue,posses-sing a higher safety and usability.
