摘要
二十一是一个集数字化、网络化、信息化的,以网络为核心的社会,随着网络的不断发展,网络的应用日益的广泛。如电子商务,网上医疗,网上娱乐,网络游戏,网络教学等等。
本次设计的题目就是红外探测报警系统
随着社会的发展和人民生活水平的不断提高,农村城镇化和人员流动性增大,社会治安状况也变得日趋复杂,目前日趋严重的盗窃犯罪突出了低龄化、团体作案以及高素质犯罪等特点,人们的安全防范意识也随之不断增强。诸如家庭、学校、工厂、办公室等场所都应该健全自身的防盗系统。如果探测到有人闯入,那么系统的声光报警电路会发出警鸣声给人们以提醒。该系统以单片机AT89S52系列为核心,采用红外线发射管和红外线接收管为发射和接收装置,由反相器芯片反相间接控制CPU工作。在CPU程序运行以后控制输出口电平使得蜂鸣器与发光二极管组成的声光报警电路同时进行声光报警。并通过单片机系统向声光报警电路发出信号,达到声光报警的目的。本论文先后介绍了红外线防盗报警器的意义、发展背景、发展前景、系统的基本电路结构和系统软件的设计。

Abstract
With the development of society and the improvement of people's living standards, rural urbanization and personnelmobity,social security situation has e plex,the
increasingly serious crime of theft has highlighted the youngerage,group crime and crime characteristics such as high quality,people’s safety awareness is also asfamily, school, factory, office and other places should improve the anti-theft system itself if the detected someone broke in, then the system will send out alarm sound and light alarm circuit sounds to the people to remind. The system based on singlechip AT89S52 series as the core, using the infrared emission tube and the infrared receiving tube for transmitting and receiving device, by an inverter inverting indirect control CPU chip. In the CPU program to run after the control of output level makes the buzzer and the light emitting prising an acousto-optic alarm circuit at the same time the sound and light alarm. And through the single chip puter system to sound and light alarm circuit sends out signals to alarm, the purpose of. This paper has introduced the infrared anti-theft alarm significance, development background, development prospects, system basic circuit structure and the software system design.
