Abstract
The utility model discloses a detector for detecting number of people based on infrared detection. The detector consists of an optical module (1), an infrared detection element array (2), a signal processing module (3) and an input-output lead (4), wherein the optical module (1) is of a Fresnel lens; the detection element array (2) is formed by a plurality of detection elements used commonly at present through being subjected to reversed polarity serial connection to form detection element pairs which are regularly arranged to be a matrix detection element array; the signal processing module (3) consists of a commonly used signal processing circuit; and the input-output lead (4) comprises a power line, a ground line and a signal output line. The detector can identify human body infrared signals in various directions of motion by using an algorithm routine recorded in a chip by the signal processing module (3), thus the infrared detection precision is improved and the detection of number of people is achieved; and detection signals with amplitude values changing along with the number of people are output.
Description
Technical field
The utility model relates to a kind of number detector based on infrared acquisition, surveys the detector that the different human body infrared radiation is determined number in the search coverage thereby specifically relate to a kind of Infrared Detection Array that adopts.
Background technology
At present, the application of the electrical equipment that some power such as air-conditioning are adjustable is more and more extensive, but the power of these electrical equipment usually needs manually to adjust according to the situations such as number are artificial, seem cumbersome, thereby realize that these electrical equipment are also just especially important according to how many Based Intelligent Control of number in the certain area, and realize that a pith of such Based Intelligent Control is exactly well behaved sensor.
With regard to the sensor that is applied to the household electrical appliances aspect, the impact (light, noise etc.) that is subject to environment owing to sound-detection gear and simple image pickup detector is difficult to realize round-the-clock detection, therefore adopts the mode of comparatively stable infrared acquisition to realize that correlation function just praised highly by people gradually.Common infrared eye mainly contains following several at present:
The first is infrared camera, namely adopt infrared imagery technique, take infrared image, this method can be taken the infrared image of the nearly all object in space, but it is but relatively more difficult to be implemented in coherent signal, the realization detection number of extracting human body in the Infrared Video Signal, the price of infrared camera is also higher in addition, is not suitable as sensor and is embedded in the electrical equipment.
The second is to use at present very widely infrared switch formula detector, why being referred to as infrared switch formula detector is because this class detector all is to adopt two to survey the infrared difference of unit's contrast at present, process the output switch pulse signal through signal, thereby can only realize unmanned detection is arranged.
The third is the active infrared detection device, namely launches infrared signal, realizes surveying by the signal of accepting the object reflection.This kind infrared eye is mainly used in anti-theft feature at present, owing to can only detect infrared ray by the correlation circumstance on the path, search coverage is narrow, and the number that is difficult to the implementation space scope detects.
Want to be implemented in the certain area by above-mentioned detector that to measure the state of how much Based Intelligent Control electrical equipment according to the people very difficult, or be that cost is higher.Therefore, invent a kind of energy simple, can comparatively accurately realize the detector of people's amount in the certain area significant.
Summary of the invention
The purpose of this utility model is to have overcome deficiency of the prior art, and a kind of sensor that can comparatively accurately measure the number in the certain area is provided, and cost is relatively cheap, easy to implement simultaneously.
In order to solve the problems of the technologies described above, the utility model is to be achieved through the following technical solutions:
Plant the number detector based on infrared acquisition, it is characterized in that: it includes optical module, infrared acquisition element array, signal processing module, input and output lead-in wire and detector body, the rear side of described optical module is provided with the infrared acquisition element array, the infrared acquisition element array is installed in the front portion of detector body, signal processing module is installed in detector body inside, the infrared acquisition element array all links to each other with signal processing module with the input and output lead-in wire, and described input and output lead-in wire is arranged on the top of detector body.
Described infrared acquisition element array is that the detection that is connected into through reversed polarity by basic infrared acquisition unit is to being arranged in by matrix.
Compared with prior art, the beneficial effects of the utility model are:
This sensor uses array of sensor elements, and by the infrared signal on the algorithm detection pyroelectricity array of sensor elements, can effectively identify the infrared signal of different human body, thereby can comparatively accurately survey the people's amount in the certain area, and can export the signal that amplitude changes with people's quantitative change, can be directly embedded on the multiple electrical equipment, realize the electrical equipment Based Intelligent Control.The simultaneously realization of element arrays is comparatively easy, thereby whole detector is easy to produce.
Description of drawings
Fig. 1 is schematic appearance of the present utility model.
Fig. 2 is composition synoptic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As shown in Figure 1, it includes optical module 1, infrared acquisition element array 2, signal processing module 3, input and output lead-in wire 4 and detector body 5 the utility model, the rear side of described optical module 1 is provided with infrared acquisition element array 2, infrared acquisition element array 2 is installed in the front portion of detector body 5, signal processing module 3 is installed in detector body 5 inside, infrared acquisition element array 2 all links to each other with signal processing module 3 with input and output lead-in wire 4, and described input and output lead-in wire 4 is arranged on the top of detector body 5.Described infrared acquisition element array 2 is that the detection that is connected into through reversed polarity by basic infrared acquisition unit is to being arranged in by matrix.
After Optical system module 1 filters out human body infrared with the process of the infrared signal in the search coverage, Refractive focusing is to pyroelectricity array of sensor elements 2, form corresponding detection electric signal, after processing via signal processing module 3 again from 4 outputs of input and output lead-in wire per capita what and signal that amplitude changes.
The undeclared part that relates in the utility model is same as the prior art or adopt prior art to be realized.
