TheApplicationandDesignoftheInfraredsensorsinanti-theftsystem
摘要
随着时代的不断进步,人们对环境的安全性提出更高的要求,很多小区都安装了智能
报警系统,大大提高了小区的安全程度,有效保证居民的人身财产安全.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它非生物.热释电红外传感器既可用于防盗报警装置,也可以用于自动控制、接近开关、遥测等领域.
介绍一种自动防盗报警系统。
该系统由热释电红外传感器、菲涅尔透镜和监控电路组
成。
这种电路把红外线的隐蔽性很好地应用于报警电路中,从而实现防盗报警功能,达到安全防护之目的。
论文研究的主要内容如下:
综合研究和分析国内外使用的各类防盗、保安报警器常用技术,总结各类传红外感器
的特点和应用前景,利用现有的通信传感器和通信技术设计一种基于热释电红外传感器防
盗报警装置。
