远程遥控电子密码锁完整本科论文.docVIP

摘要 随着社会科技的发展和人们的生活水平的提高，如何实现家庭防盗这一问题变的尤其的突出。各种防盗密码锁层出不穷，其中，红外遥控密码锁系统由于其必威体育官网网址性高，使用灵活性好，安全系数高，除了具有普通电子密码锁功能的同时，还增加了遥控功能，给人们的生活安全保障带来了极大地便利。 本设计以AT89C51为中央控制器，运用了两块单片机芯片，一片实现红外解码，一块用来按键控制，二级管显示以及数据存储，通过查找资料确定各个模块的功能及实现方法。首先在软件上进行调试，再根据硬件修改调试软件，最后将各个模块合理组合在一起，达到预计的功能与目标。论文中给出了红外发送器与红外接收器的设计电路的典型设计电路部分和具体应用方法,设计出了一种对遥控信号进行准确译码方法和电路系统能完成开锁、出错报警、超次锁定、修改用户密码等基本的密码锁的功能，并且能实现遥控、本机键盘开锁、声光提示等功能。关键：单片机红外线遥控开锁密码ABSTRACT With the development of society and peoples living standard enhancement, how to realize the anti-theft family this problem becomes particularly prominent. A variety of anti-theft cipher lock emerge in an endless stream, wherein, the infrared remote control cipher lock system due to its high secrecy, the use of flexibility good, high safety factor, in addition to a common electronic password lock function at the same time, also increase the remote control function, to the peoples life security brought greatly facilitates. This design using AT89C51 as central controller, using two chip, a realization of infrared decoding, a block to the button control, two level display and data storage, search through the data to determine the function of each module and the realization method, first in the software debugging, then according to modifications to the hardware debugging software, finally will each reasonable modules are combined together, achieve the expected goal and the function of. Papers presented in the infrared transmitter and the infrared receiver circuit design and electronic password lock the typical design of circuit part and the concrete application method, designed a pair of remote control signals accurately decoding method and circuit. In this design, infrared remote control locks and PC machine, a combination of database, to achieve the timely, powerful management capabilities, the infrared remote control system to better improve. The system can complete the lock, error alarm, super lock, modify the user password basic password lock function, and can realiz
