摘要
多用户密码锁具有保密性好、使用灵活、安全系数高等特点。用户无需更换密码就可防止前一用户的再次进入,提高了另一用户居住的安全性。它的使用可以减少换锁带来的麻烦,节约成本、提高安全性。基于多用户密码锁设计方案,介绍了AT89C51单片机芯片,给出了多用户密码锁的硬件设计及软件设计内容。
The multiuser combination lock is characteristic of secrecy,flexibility,and safety.The master user does not need to replace the password to prevent the preceding user entry once more,thus enhancing the housing security of another user.Therefore its use may save the trouble of changing the lock to reduce the cost and enhance the security.Based on the multiuser combination lock design,the at89C51 monolithic integrated circuit chip is introduced,and hardware and software design of the multiuser combination lock are given.
