摘要
基于热释电红外传感器的工作原理,设计了一种被动式热释电红外报警器。主要用于家居安全,探测有无外人闯入。该系统由热释电红外传感器、菲涅尔透镜和监控电路组成。系统把红外线的隐蔽性很好地应用于电路中,选用了新一代红外信号处理器BISS0001,设计了放大滤波电路,红外信号处理电路,并加入语音芯片,模拟警笛声音,达到防盗目的。经多次实验,该系统反应灵敏,抗干扰能力强,安全可靠。
Based on the working principle of pyroelectric infrared sensor,the passive pyroelectric infrared alarm system is designed for safety of residence house to detect whether outsiders enter or not.This system was made of pyroelectric infrared sensor,Fresnel lens and monitoring circuits.Infrared signal processor BISS0001 was chosen,amplifying and filtering circuits and infrared signal processing circuit were designed on basis of the concealment of infrared,then the voice chip was utilized to simulate alarm voice for warning thieves and burglars.After many experiments,it represented that the system has sensitive response,high anti-interference ability and safe and reliable performance.
