摘　　要：为了解决机械锁结构简单及安全性差的问题,设计并制作了多功能电子密码锁。以STC89C52单片机为主要控制单元,采用EEPROM芯片来完成密码的存储,采用LCD液晶显示屏提示程序运行状态、显示时间和温湿度,利用门磁传感器结合蜂鸣器组成报警系统。独特之处在于装置中设置了管理员万能密码,便于统一管理。经过多次试验模拟,装置运行出错率为零,完全达到了预期效果。In order to solve the problem that the mechanical lock has simple structure and poor safety, this paper designs and manufactures the multifunetional electronic password lock. It uses STC89C52 microcontroller as the main control unit and complete the password storage with the use of the EEPROM chip, LCD liquid crystal display prompts operation procedures, steps, display of time, temperature and humidity, magnetic sensor, combined with the buzzer, makes up alarm system. The innovation is that the device sets the master password, which is beneficial for property management. Through many simulation tests, the error rate of the device operation is zero, achieving fully the expected result.
