摘 要
利用热释电红外传感器的红外辐射与红外探测的原理,设计的一种新型探测器,测量范围广, 响应速度快, 灵敏度高,抗干扰能力强,安全可靠。当检测到有被测物体进入测量范围时,系统自动发出声光报警信号,等待一段延迟时间后自动消除报警信号,也可手动解除报警信号。并且能够检测人数及控制人数的最大容量,当探测头探测到有人经过时,系统自动计数加一,并通过键盘控制最大容量人数,如果探测到的人数超过最大容量人数时则发出自动报警信号,并通过LED显示检测到的人数与最大容量报警人数。
关 键 词:热释电传感器;声光报警;单片机

ABSTRACT
Using the principle of pyroelectric infrared sensor’s infrared radiation and infrared detection,Designed a new detector,wide measurement range,fast response,high sensitivity,anti-interference ability and reliable .When detect have measured objects enterd the measuring range,the system automatic produce sound and light alarm signals,wait sometimes automatic eliminate the alarm signal,sure manual can do.Detection and control the number of the maximum people.When probed someone enter,the system automatic count plus one,by keyboard control the number of people.If probed the people more than the maximum,have alarm signals.Through the LED show the number of detected people.
KEY WORDS: Pyroelectric infrared sensor; Sound and light alarm signals; SCM
