摘要随着现代化技术的发展，犯罪手段更趋智能化、现代化，作案手法也更加隐秘，所以人们更需要一种智能的家居安防报警系统。在白天上班不能顾及到家中情况时，智能报警器能可靠地进行日常安全防护工作，及时发现恶意侵入并报警，吓退歹徒，以便户主将险情消灭在萌芽状态，这样能在更大程度上，使人们的生命财产安全得到保障。

本课题将设计一种可以远程遥控的红外报警器，该报警器利用DYP-ME003热释电红外传感器进行监控、采用高性能低功耗的STC89C52单片机作为微处理器。本文首先论述了热释电红外报警器存在的价值，研究的背景和目的，介绍了目前国内外热释电红外报警器的发展现状，解释了热释电红外传感器的内部结构以及工作原理。然后根据报警控制系统功能要求制定总体设计方案。本设计包括硬件设计和软件设计两部分。硬件设计部分主要包括单片机控制模块、红外检测模块、报警模块、显示模块等。软件设计部分使用C语言编写程序。最后对系统进行了仿真测试及硬件测试。该红外报警器制作简单、成本低、安装方便，而且防盗性能稳定，抗干扰能力强、灵敏度高，在日常生活中可以起到有效的监控报警作用。86167

Abstract With the development of modern technology, crime means more intelligent and modern, method of committing crime is also more secretive,so it is urgent to find a kind of intelligent home security alarm system。It can not take into account the situation at home when we working outside,the intelligent alarm can keep the daily safety work safely and reliably, timely detection of malicious intrusion alarm and deter criminals, so that households owners danger elimination in the bud,and people's lives and property are protected in a greater extent。

The project introduces a remote control with the DYP-ME003 pyroelectric infrared sensor monitoring,use the high performance and low power STC89C52 microcontroller as a microprocessor。This paper discusses the value of pyroelectric infrared alarm,and the background and purpose of the study, it introduces the current development of pyroelectric infrared alarm;It explains the internal structure and working principle of pyroelectric infrared sensor; Then develop the overall design scheme according to alarm control system functional requirements。The design includes hardware design and software design in two parts, The hardware design mainly includes MCU control module, infrared detector module, alarm module, a display module; Software design use C language to write programs。Finally, the system has carried on the simulation test and hardware test。 With the advantages of producing simple, low cost, easy installation, security and stable performance, strong anti-interference ability, high sensitivity, the infrared alarm can have effective monitoring alarm function in daily life 。
