毕业设计（论文） 基于单片机的电子密码锁设计 基于单片机的电子密码锁设计 摘 要 随着科技和人们生活水平的提高，如何实现防盗这一问题也变的尤其突出。由于传统机械锁构造简单，被撬事件源源不断；而电子密码锁必威体育官网网址性高，使用灵活性好，安全系数高，所以受到了广大用户的青睐。 电子密码锁是一种通过密码输入来控制电路或芯片工作，从而控制机械开关的闭合，完成开锁、闭锁任务的电子产品。应用较广的电子密码锁是以芯片为核心，通过编程来实现的。 设计以STC89C51单片机作为密码监控装置和控制核心，结合键盘电路，LCD显示电路，报警电路和开锁机构，利用单片机灵活的编程设计和丰富的I/O端口及其控制的准确性通过软件程序来控制整个系统实现电子密码锁的基本功能。软件设计采用自上而下的模块化思想，使系统朝着分布式、小型化方向发展，使系统的可靠扩展性和运行稳定性增加。测试结果表明，设计各项功能已达到设计要求。 关键字： 单片机；STC89C51；电子密码锁；报警 Design of Electronic Combination Lock Based on Single Chip Microcomputer Abstract Along with the improvement of science and technology and the living level of people, how realize to guard against theft this problem also become especially. Because of the simple construct of traditional machine lock, the affairs of theft is commonly；The electronic combination lock is safer because of its confidentiality, use flexibility is good, the safety coefficient is high, being subjected to the large custom close. The electronic combination lock is electronic products, which control the mechanical switch by the control circuit or chip when you input a password. Now the widely used electronic locks are based on the chip and achieve the function by programming. The design by single chip microcomputer STC89C51 act as the combination lock monitoring device detection and control core, combining with key circuit, LCD display circuit, an alarm circuit and unlocking mechanism, using a flexible programming design and rich I/O port of microcontroller, and its control by software program to control the whole system to realize the electronic combination lock. The design thought from top to down, to make the system toward wear distribute type, turn to the direction development of small, strengthen the system and can expand the stability and circulate. Test the result state, various functions of this system are already all request of this design.
