基于单片机的电子密码锁设计

Design of Electronic Password Lock Based on MCU

传统的机械式锁具,在很大的程度上,已经不能够去满足现人类对安全性能的要求,特别是在财产安全,住宅安全等方面。需要研究出让人们觉得更加可靠、更加安全、方便快捷的锁具。本文基于AT89C51单片机,对电子密码锁进行了总体设计和硬件电路的设计。该密码锁备以下基本特点:体积小、低价格、低功耗、操作简便等。

Traditional mechanical locks,to a large extent,have been unable to meet the requirements of human safety,especially in the property security,housing security and other aspects.There is a need for research into locks that people feel are more reliable,safe and convenient.In this paper,based on AT89C51 single chip microcomputer,the overall design of the electronic code lock and the design of the hardware circuit.The password lock has the following basic features:small size,low price,low power consumption,easy operation,etc.
