Abstract：Although the rapid development of science and technology brings convenience to our life，it also challenges peoples information security and privacy security. The previous door locks cant meet peoples current needs. In order to better maintain peoples security and privacy，more and more types of locks have been developed. The emergence of electronic password lock has changed the shortcomings of simple lock opening process and poor security performance in the past. After entering the market，it is widely used in families，supermarkets and other places. Electronic security code lock is controlled by electronic circuit. It is better than traditional lock in security，flexibility and operation convenience by using touch keyboard. In this paper，the general design process of the electronic security code lock of single chip microcomputer and the design ideas and circuits of each component are simply described，and the regulation of the software and hardware of the electronic security code of single chip microcomputer is simply described.

Keywords：MCU;electronic security combination lock;electronic combination lock design

锁具的研制既要操作简单，还需要达到保密性良好这一点要求，这是所有锁具在研制时的两大要素。传统的锁具易因钥匙丢失造成无法开锁的现象，而靠IC卡控制的鎖具虽然方便了不少，但IC卡在一些磁性较强的地区会失去磁性，也有可能导致出现无法开锁的情况。这两类锁具都没有达到真正意义上的方便和安全。计算机行业的发展影响了许多行业，电子锁的出现很大程度上是由于计算机行业的发展及其与各个领域的融合与应用。电子密码锁在保证传统锁具普遍具有的性能外，因其自身的特性，具有密码重置的功能，更加人性化，又因其操作方法简单，成本低且安全性高等优点，其应用价值与发展前景都十分良好。……
