Passive infrared invasion detector checking method and the checking device

Abstract

The invention relates a detection method of a passive IR intrusion detector and a detecting device using the method, for solving the problems of the passive IR intrusion detector such as inaccurate detection result, low detection speed, and large labor and time consumption caused by the changing electromagnetic energy radiated by target human body. The method comprises using a black body radiation source as IR radiation source, adjusting the black body radiation source to produce IR radiation so as to form a discontinuous pulse radiation equivalent to walking person, and detecting whether thepassive IR intrusion detector is qualified. The detecting device is positioned at a position corresponding to the emitting hole of the black body radiation source, a speed-adjustable rotation disc having a group of through holes corresponding to the emitting hole is equipped, the black body radiation source is connected with a slider and a mount support to form a mobile connection capable of relatively sliding, and a movement transfer device is equipped at corresponding position of the IR radiation region of the black radiation source. The invention has the advantages that the detection method has simple and rapid detection and uniform standard, and the detecting device has simple structure, convenient use and low cost.

Description

Technical field [0001] The invention relates to a detection method of a passive infrared intrusion detector and a detection device thereof, in particular to a method for detecting whether a product of a passive infrared intrusion detector is qualified by using a blackbody radiation source instead of a human body, and a detection device using the method . Background technique [0002] According to Planck's radiation theorem, any object with an absolute temperature greater than zero can radiate electromagnetic energy. The intensity of electromagnetic energy radiated by an object is related to the temperature of the object and the radiation capacity of the surface of the object. The spectral distribution of radiation is also related to the temperature of the object. Infrared is usually It refers to electromagnetic waves with a wavelength from 0.75 to 1000 microns. The electromagnetic energy radiated by the human body belongs to the infrared wavelength range. The passive infrare...

Problems solved by technology

[0004] In order to overcome the existing technology, the passive infrared intrusion detector products use the human body to move within the effective working range of the detector when they leave the factory. There is a large gap in the detection results of the detectors and the detection speed is slow, labor-intensive, time-consuming, and unable to adapt to the technical shortage of the detection needs of mass production. The present invention proposes a passive infrared intrusion detector detection method and a detection device for the method. , the present invention uses a blackbody radiation source to simulate the electromagnetic energy radiated by the human body to be measured, and implements quantitative detection of passive infrared intrusion detector products, so as to realize the scientific unity of detection of detector products
