Human body infrared detector with self-regulating function and working method thereof

Abstract

The invention relates to a human body detector, in particular to a human body infrared detector with a self-regulating function. The human body infrared detector comprises a master control unit, a passive infrared sensor circuit unit electrically connected with the master control unit through a signal amplifying circuit unit, a multicolor light-emitting circuit unit, a signal output circuit unit and a power source circuit unit for supplying power, wherein the multicolor light-emitting circuit unit and the signal output circuit unit are electrically connected with the master control unit. The multicolor light-emitting circuit unit comprises a plurality of different-color light-emitting elements which are respectively and electrically connected onto the master control unit, and the passive infrared sensor circuit unit comprises a passive infrared sensor which is arranged at the position where direct light or diffuse reflection light of all light-emitting elements can be received. The invention further discloses a working method of the human body infrared detector with the self-regulation function. The working method includes steps of: (1) human body detection; and (2) automatic regulation. The human body infrared detector is good in stability and capable of resisting changing of ambient light, and a working state lamp is attractive.

Description

technical field [0001] The invention relates to a human body detector, in particular to a human body infrared detector with self-adjusting function and its working method. Background technique [0002] The electronic detection products currently on the market are generally composed of passive infrared sensors, sensor signal amplification circuits, signal processing circuits, power circuits, and signal output circuits. There are also working indicator lights for selection. The advantage of this type of product is that it is relatively mature. , widely accepted and used by users, but there are still relatively prominent deficiencies in use: [0003] 1. The parameter index of the passive infrared sensor used in the detector is discrete and will drift with time, and the consistency and stability of the detection performance of the product is not good; [0004] 2. With the different use environments and day and night changes of the detector, the illuminance of the working enviro...

AI Technical Summary

Problems solved by technology

[0006] In order to overcome the shortcomings of traditional detectors that drift in performance over time and are easily affected by changes in ambient light, the purpose of the present invention is to provide a human body infrared detector with a self-adjusting function that is stable and resistant to changes in ambient light
