红外防盗报警系统的设计

吴勇（湖南人文科技学院湖南娄底417000）

摘要：随着时代的不断进步 ,很多小区都安装了智能报警系统 ,有效的保证了居民人身财产安全.本系统采用了热释电红外传感器，它的制作简单、成本低、安装比较方便，而且防盗性能比较稳定，抗干扰能力强、安全可靠。本红外线防盗报警系统由热释电红外传感器、报警器、单片机控制电路、LED 控制电路及相关的控制管理软件组成。用户终端完成信息采集、处理、数据传送、功能设定、本地报警等功能。终端由中央处理器、输入模块、输出模块、通信模块、功能设定模块等部分组成。处理器采用51系列单片机AT89C51，整个系统是在系统软件控制下工作的。

本设计就是为了满足现代住宅防盗的需要而设计的家庭式电子防盗系统。因此，本文提出一种基于以单片机技术为核心的红外防盗报警器的设计，具有一定的研究价值和实际应用意义。

The design of infrared ray alarm system

Yong Wu

(Hunan Institute of the Humanities Science and Technology Hunan Loudi 417000) Abstract：With the development of society, So there are more and more intelligent alarm system having been set in housing estates, obviously, they guarantee the person and belongs effectively. The system adopts pyroelectric infrared ray sensor which is made simply, cost lowly, install conveniently, what’s more, the system has steady prevention of thievery and interference, great sensibility and reliability. The infrared ray alarm system is made up of pyroelectric infrared ray sensor, single-chip microcomputer control circuit, LED control circuit and the relative control manage software. The function that collecting information, handling information, sending data, setting up features, making alarm natively is used by user terminal. In addition, the user terminal is made up of CPU, input modules, output modules, communication modules, function-set modules and so on, while CPU adopts 51 size single-chip A T89C51, and all parts of the system are working under the control of system software.

The design of this experiment is a household electric alarm system, which have the aim of satisfying the people’s need of housing prevention. So this thesis that is based on single-chip to put an infrared ray alarm system have great research value and practical meaning.

Key Words: single-chip, pyroelectric infrared ray sensor, collecting information, alarm circuit
