1、 1 毕业设计（论文） 门磁红外报警器的设计门磁红外报警器的设计 系 部： 专 业： 班 别： 姓 名： 学 号： 指导老师： 日 期： - 1 - 摘 要 随着时代的不断进步，人们对自己所处环境的安全性提出了更高的要求，尤其是在 家居安全方面，不得不时刻留意那些不速之客。现在很多小区都安装了智能报警系统， 因而大大提高了小区的安全程度，有效保证了居民的人身财产安全。由于红外线是不见 光，有很强的隐蔽性和保密性，因此在防盗、警戒等安保装置中得到了广泛的应用，此 外，在电子防盗、人体探测等领域中，对射红外探测器以其价格低廉、技术性能稳定等 特点而受到广大用户和专业人士的欢迎。 本文介绍了一款结构
2、简单,成本低廉,稳定性比较高的红外报警设计的实现. 在本文 中主要介绍了该设计的硬件电路、软件设计流程、系统测试。门磁红外报警器采用 AT89S52 单片机，单片机是本系统的核心器件。以 PT2272/2262,315M 射频来实现各种 传感信号的编解码发射与接收， LCD1602 实时显示密码输入状态， 通过遥控模块可以很 方便地进行远程操作处理,很适合在小区推广。 关键词:PT2262/2272；红外传感；单片机； - 2 - Abstract With time unceasing progress, people located the environment security to
3、oneself to set a higher request, Specially to safety of their living room. Now most plots all have installed the intelligence alarm system, Thus enhanced the plot safety rate greatly, this effectively guaranteed inhabitants person property safety. Because infrared is not exposed to light, Has strong
4、 confidentiality and the secrecy, Therefore in security, and so on security An Bao installed obtained the widespread application, In addition, In electron security, domains and so on in human body survey, Correlation infrared acquisition aid by its price inexpensive, technical performance stable and
5、 so on characteristics, Receives the user community and professionals welcome. This article introduced a section structure Infrared reports to the police the design realization which is simple, low cost, high stability quite. This thesis mainly introduces the hardware electric circuit, software desi
6、gn process, testing system. The gate magnetism infrared alarm apparatus use at89S52 monolithic integrated circuit, The monolithic integrated circuit is this system core component. Realizes each kind of sensing signal by the PT2272/2262,315M radio frequency to arrange the decoding launch and the receive, LCD1602 real time display password input condition, May carry on long-distance operation processing very conveniently through the remote control module, suits very much in the plot promo
