Abstract
The utility model relates to a detective device using infrared ray, which is applied to a human body infrared ray intrusion alarm. The utility model is characterized in that the change of infrared ray radiant quantity in a warning zone is used for driving the alarm to work to send out warning signals; a sensor adopts a double light-sensitive element pyroelectric electric sensor. Through the utilization of the optical splitting principle, each beam of infrared ray of fresnel lens, which is displayed to windows, generates two detection zones; the fresnel lens is composed of three-layer structure to form a warning viewing angle which is 84 DEG, and the effective working distance is greater than 15 meters. Accordingly, the warning line in the warning zone is increased to two times, and the sensitivity of the detective device is enhanced.
Description
The utility model relates to a kind of infra-red detection device, mainly is applicable to human body infrared intrusion alarm unit.Existing human body infrared sniffer complex structure, price is higher, and power consumption is big, is not easy to hidden and installation.
The purpose of this utility model is to provide a kind of passive infrared sniffer, promptly utilizes in the security area variation of amount of infrared radiation to drive alarm work and sends the signal of warning, and it is characterized by infrared ray sensor and selects two photosensitive first pyroelectric sensors for use.Utilize the optics splitting principle, each light beam that these sensitive detection parts can make Fresnel Lenses display window produces two detecting areas, thereby the warning line in the security area is doubled, and has improved the sensitivity of surveying greatly.
