ABSTRACT
Electronic code lock is commonly used in modern life, encryption tools. It overcomes the mechanical lock code less, the shortcomings of poor safety performance, especially the micro-controller intelligent electronic lock, electronic lock is not only functional, but also the introduction of intelligent management features, so that the locks have a more High security and reliability
Electronic code lock is commonly used ARM and SCM, SCM implementation is relatively simple ARM, function better, so the use of SCM control more. Lock with Microcontroller assembly language programming often use, most use digital display. The article designed the use of portable electronic locks and readable high-level language C language, easy to modify and change in function; use more convenient. From the economical point of view, the use of AT89C51 to design a single chip with a password set, multiple alarms and test the password function to prevent the electronic code lock, through Protues software successfully simulated.
Keywords: electronic password lock,AT89C51 SCM, C language alarm
