摘 要:本文介绍了依据多谱勒效应的原理,采用热释电红外探头(LN074B)接收到的微弱信号加以放大,然后驱动继电器,制成红外热释电感应开关.本开关能探测来自移动人体的红外辐射,只要人体进入探测区域,开关会自动开启.该设计可作为企业、宾馆、商场及住宅的走廊、楼梯、电梯间、卫生间、库房等处的自动开关,起到“人来灯自亮,人走灯自灭”的作用,既新颖方便,又节约用电,在某些场所还能起到威慑盗窃活动的防范作用.本设计结构简单,本身不发任何类型的辐射,器件功耗很小,价格低廉,隐蔽性好,应用范围广,所以可以通过扩展而达到实际的应用.

this article will normally introduce the theory of dopuler effect,which advance LN074B to zoom out micro-signal.then drive the relay,complete the infraed-heat electric on-off.this switch can mensurate moving-body infraed ray.once coming into the mensurate area,the switch will automatically turn on.this invitation could be used as auto-on-off in corporation,hotel,mall and could induce house like the lane,stairs,bathroom,stockroom.bringing the effectness that coming on,leaving off.it is innovate and convient,also reduce the expanse of electricity,could resist the steal activities.its structure is very simple.it can emit no ray,small size,low price,well cover-up,widely used,attach to practical advantage when spreaded.

Abstract: In this paper, based on the principle of Doppler effect, a pyroelectric infrared probe (LN074B) to receive the weak signal to zoom in, and then drive relays, made of pyroelectric infrared sensor switch. The switch can detect human movement from the infrared radiation, as long as the human body into the detection region, switch will automatically open. The design can be used as enterprises, hotels, shopping centres and residential corridors, stairs, elevators, bathrooms, etc. Treasury automatic switch, a "people to come to light since Liang, who since the lights go out," the role of both new convenience, And conservation of electricity, in some places can play a deterrent role in preventing theft activities. The design is simple, do not own any of the types of radiation, the device power consumption is very small, inexpensive and concealment, and wide application, the ability to expand and achieve practical application.
