基于AT89S52芯片数字机械安全锁设计

摘要

本设计基于AT89S52芯片技术,采用机械钥匙与数字芯片密码结合锁定锁芯的方法.将存储芯AT24C02嵌入钥匙上用来存储密码信息,通过读取锁内部存储芯片上的密码信息和钥匙芯片的密码数据进行匹配,同时要求锁头与钥匙机械匹配,进而实现锁的开启.本设计的开锁方式与传统的机械锁开门方式一致,方便被广大用户接受,结合内置芯片技术,锁的安全性得到了极大的提升.%This design is based on the AT89S52 chip technology,and adopted the method integrated mechanical key with digital chip password to lock the cylinder.The memory chip AT24C02 is embedded in the key to store the password information,and the password information of the internal memory chip the in the lock and the password data in the key chip to match is read out,at the same time,combining with mechanical match of key and lock,and the lock is unlocked.The unlock mode of this design is similar to the one of mechanical lock,so it is accepted by the majority of consumers,while its safety performance has been greatly improved.
