s110, determining a detection area for detecting the passenger flow according to a signal detection range formed by superposing the pyroelectric sensor, the Fresnel lens and the shell with the hole in the pyroelectric acquisition module.
The pyroelectric collection module in the embodiment can detect infrared signals released by a human body and collect response signals of infrared radiation changes, and is suitable for statistics of auxiliary passenger flow in an online off-line physical store.
The pyroelectric acquisition module in this embodiment includes a pyroelectric sensor, a fresnel lens, and a housing with a hole. Wherein, Pyroelectric Sensor is also called Pyroelectric Inductor (PIR), Pyroelectric collection module can realize the function that detects Infrared signal mainly relies on Pyroelectric Sensor to Infrared signal's detection, because any heat-generating body all can produce the Infrared ray, the Infrared ray wavelength of radiation is relevant with the temperature of heat-generating body, the wavelength of the Infrared signal of human release can be along with human body temperature change, consequently, Pyroelectric Sensor's theory of operation mainly is the electric charge signal that electric charge produced along with human temperature change after detecting internal device polarization, and pass through impedance transformation with this electric charge signal and convert voltage into, present the detection result to Infrared signal with the form of voltage. The Fresnel lens is taken as the 'glasses' of the pyroelectric sensor, can be arranged outside the pyroelectric sensor, and whether the Fresnel lens is matched with the pyroelectric sensor or not can directly influence the use efficacy of the pyroelectric acquisition module, and the Fresnel lens mainly has two functions: firstly, focusing is carried out, namely, infrared rays in a detection area are effectively concentrated on the pyroelectric sensor; secondly, the detection area is divided into a plurality of bright areas and dark areas, so that the moving object entering the detection area can generate a variable pyroelectric infrared signal on the pyroelectric sensor in a temperature change mode. In this embodiment, set up the shell that has the hole in the pyroelectric collection module, this shell setting is in fresnel lens's outside, and fresnel lens and pyroelectric sensor need be covered by the cage to the size of shell, is provided with a plurality of holes on the shell, and the shell that has the hole can carry out the part to the infrared signal of fresnel lens focus and shelter from, retrains the signal detection scope of pyroelectric collection module to the improvement distinguishes the precision that detects to a plurality of infrared signal that come from a plurality of human releases.
In this embodiment, a detection area for detecting the passenger flow volume may be determined according to a signal detection range formed by superimposing the pyroelectric sensor, the fresnel lens, and the housing with the aperture, that is, the position relationship between the pyroelectric acquisition module and the detection area may be further determined.
In a specific implementation manner, determining a detection area for detecting a passenger flow volume according to a signal detection range formed by superimposing a pyroelectric sensor, a fresnel lens and a shell with a hole in a pyroelectric acquisition module may include the following specific steps:

In another specific example of this embodiment, the pyroelectric collecting module is installed in a side direction, that is, the pyroelectric collecting module can be installed in a side direction of a physical store entrance hall, as shown in fig. 5, a circumferential angle of an original signal detection range of a pyroelectric sensor in the pyroelectric collecting module projected in a Y direction is 112 degrees, a circumferential angle of a projection in an X direction is 100 degrees, a fresnel lens in the pyroelectric collecting module covers an outer portion of the pyroelectric sensor, so that the original signal detection range of the pyroelectric sensor is narrowed to a candidate signal detection range, a circumferential angle of a detection area after being narrowed projected in the Y direction is 40 degrees, and a circumferential angle of a projection in the X direction is 12 degrees, a housing with a hole is provided outside the fresnel lens, the housing can be provided with a plurality of holes according to actual business requirements, and the position of the hole can determine a range of an infrared signal refracted by the fresnel lens, the shell covers the Fresnel lens, the candidate signal detection range is further narrowed by blocking part of infrared signals, the narrowed detection area is 30 degrees in the circumferential angle projected in the Y direction, the narrowed detection area is 7 degrees in the circumferential angle projected in the X direction, and the detection area for detecting passenger flow is obtained, as shown in fig. 6, the triggering induction area in fig. 6 is the detection area for detecting passenger flow.
Further, as can be seen from fig. 6 and 5, the installation position of the pyroelectric acquisition module is horizontally perpendicular to the detection region, specifically, the installation position of the pyroelectric acquisition module is perpendicular to the projection region of the detection region along the Y direction; the Fresnel lens is arranged above the pyroelectric sensor, and in order to narrow the original signal detection range of the pyroelectric sensor, a main light condensation area of the Fresnel lens and a pyroelectric detection area in the pyroelectric sensor are in a crossed position relation; the casing is installed above the fresnel lens, and in order to narrow the range (candidate signal detection range) in which the fresnel lens refracts the infrared signal, the aperture on the casing and the primary light-condensing region of the fresnel lens are in a cross positional relationship.
As can be seen from the above two specific application examples, no matter the pyroelectric collecting module in this embodiment is vertically installed at the top of the physical store entrance or horizontally installed at the side of the physical store entrance, the detection area for detecting the traffic is determined by the signal detection range formed by the pyroelectric sensor, the fresnel lens and the casing with the aperture in the pyroelectric collecting module, the effective triggering range of the detection area is as close to a small sector as possible, the problem that the front foot and the rear foot of the traditional infrared sensing technology can only count according to one person when entering a physical store is solved, the vertical projection thickness of the detection area determined in the embodiment is close to that of a human body, the method can effectively distinguish and count two or more people triggering the detection area and following the front and the back feet in the same time, and improves the counting precision of the passenger flow entering the physical store.
And S120, when the detection area is triggered, acquiring a response signal of the pyroelectric acquisition module for detecting infrared radiation change in the detection area.
The detection region is a space concept and comprises a vertical range region and a horizontal range region, whether the detection region is triggered or not can be judged from the vertical range region and the horizontal range region respectively, under one condition, when the vertical range is larger than the horizontal range, once a moving pedestrian enters the vertical range, the detection region is considered to be triggered, and at the moment, the pyroelectric acquisition module can be driven to detect infrared radiation change caused by an infrared signal released by the pedestrian in the detection region to generate a response signal; in another case, when the horizontal range is larger than the vertical range, once a moving pedestrian enters the horizontal range, the detection region is considered to be triggered, and then the pyroelectric acquisition module can be driven to detect the infrared radiation change caused by the infrared signal released by the pedestrian in the detection region, so as to generate a response signal.
In an example of this embodiment, as shown in fig. 3, when the pyroelectric collecting module is installed at a top end of a hall door of a physical store, when viewed from a horizontal direction, a width of a signal detection range of the pyroelectric collecting module projected on the ground along a Y direction is 0.3m, and a length along an X direction exceeds a width of a gate in the hall, that is, a horizontal range projection area of the detection region is larger than a vertical range projection area, whether the detection region corresponding to the pyroelectric collecting module is triggered can be determined by whether a pedestrian passes through a trigger sensing region of the ground horizontal projection, if a pedestrian crosses into the trigger sensing region, it is determined that the detection region is triggered, and the pyroelectric collecting module is driven to detect a change in infrared radiation caused by an infrared signal released by the pedestrian in the detection region, so as to obtain a response signal generated by the pyroelectric collecting module.
