基于单片机的电子密码锁的设计 摘 要 本设计是基于单片机的电子密码锁设计方案。根据要求，给出了该单片机密码锁的硬件电路和软件程序，同时给出了单片机型号的选择、硬件设计、软件流程图、单片机存储单元的分配、汇编语言源程序及详细注释等内容。 该电子密码锁充分利用了51系统单片机软、硬件资源，引入了智能化分析功能，提高了系统的可靠性和安全性。本系统由单片机系统、矩阵键盘和报警系统组成。系统能完成开锁、超时报警、超次锁定、管理员解密、修改用户密码基本的密码锁的功能。另外，电子密码锁若与串行通信结合在一起将会成为宾馆、工厂、学校等需要进行统一管理的建筑群不可缺的商品。 机电一体化的电子密码锁，其功能大大超过弹子锁，且性能更稳定、更安全。其特点，首先必威体育官网网址性好，其次编码可变；其三误码输入保护；其四停电不掉码。由于自身的优势，电子密码锁会受到越来越多人们的欢迎，使用会越来越广泛，同时，也将会被社会所接受认可，并与弹子锁平分秋色。 关键词: AT89C2051 自动报警 电子密码锁 Design of Electronic Coded Lock Based on MCU Abstract This design is locks the design proposal based on monolithic integrated circuit’s password according to the request has given the hardware electric circuit and the software procedure which this monolithic integrated circuit password locks simultaneously has given monolithic integrated circuit model contents and so on choice hardware design software flow chart monolithic integrated circuit memory cell assignment assembly language source program and detailed annotation. This electronic combination lock could use 51 system monolithic integrated circuit software and hardware resources fully, has introduced the intellectualized analysis function, enhanced systems reliability and the security, moreover, electronic combination lock, This system consists of single-chip microcomputer system, matrix keyboard, LED display and alarm system. System to complete the unlock, overtime alarm, lock, administrators decrypt, modify the user s password locks the basic functions.if with the serial communication unified will become the guesthouse, the factory, the school and so on to need together to carry on the commodity which the global administration the architectural complex could not lack. Integration of machinerys electronic combination lock, its function surpasses the spring lock greatly, and the performance is stabler, is safer. Its characteristic, the secrecy is first good, next the code variables; Its three error code input protection; Its four pow
