摘 要
随着时代的不断进步,盗窃、入室抢劫等刑事案件的多发使得人们越来越渴望有一个安全生活的空间。传统的防盗门窗越来越不能满足人们日常防范的要求，因此人们迫切需要一种智能型的家庭安全防范报警系统。目前国内使用的各类防盗、保安报警器基本都是以超声波、主动式红外发射/接收以及微波等技术为基础。而这里所设计的被动式红外报警器则采用了美国的传感元件——热释电红外传感器。这种热释电红外传感器能以非接触形式检测出人体辐射的红外线，并将其转变为电压信号，同时，它还能鉴别出运动的生物与其他非生物。热释电红外传感器既可以用于防盗报警装置，也可以用于自动控制、接近开关、遥测等领域。由于单片机具有体积小、价格低、集成度高等突出优点,用单片机来开发防盗系统能使系统易于操作，且花费较小，因而具有广泛的应用性。所以该设计以热释电红外传感器为信号感测器件，单片机STC89C52作为控制器件，采用喇叭发声作为报警装置。并利用Labview软件进行防盗监控。

Abstract
As time progress, People more and more hope a safely living space for the increasing crime of embezzling and looting. The traditional security doors and Windows can not meet the People’s Daily requirements, So people urgently needs a household intelligent safety alarm system. At present, all kinds of guard against theft, security alarms are based on the ultrasonic, active infrared emission/receiving and microwave technology in china. But, in this designing,we using Passive infrared alarm is American Sensing elements -- pyroelectric infrared sensors. This kind of pyroelectric infrared sensors can use the non-contact form to detect the infrared radiation of Human body, and changes it to become the voltage signal. At the same time, It also can identify the biological and other non-living things. Pyroelectric infrared sensor is not only used in the guard against theft and alarm system,but also used in the field of automatic control, proximity switch, remote sensing and so on. Because of the chip has advantages of small size, low price, high integration. To develop the security system based on single chip can make the system easy to operate, and less cost, which has a wide application. So this design we use pyroelectric infrared sensor for signal sensors, STC89C52 MCU for control device, and using a loudspeaker for alarm device.And use labview software for security monitoring.
