本文介绍了一种电子密码锁的实现。该电子密码锁采用1一wire总线芯片Ds2401作为密匙，锁体采用高可靠性的单片机PIC16c63来完成密码识别和开锁控制，用I2C总线接口的EEPROM 芯片AT24c02来完成密码的存储和修改，可 掉电保存密码。整个系统安全可靠，稳定性高。-This paper introduces an electronic code lock realize. The electronic locks used one chip one wire bus Ds2401 as key, lock body for high reliability PIC16C63 microcontroller identification and password to complete the unlock control, with I2C bus interface EEPROM chip AT24C02 to complete the password storage and revised down to save the password. The entire system is safe and reliable, high stability.
