Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] It should be understood that the terms used in this application specification are only for the purpose of describing specific embodiments and are not intended to limit the application. As used in this application specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0037] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0038] The embodiments of the present application provide a non-contact bio-information collection device based on a thin film. Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0039] See also Figure 1 , Figure 1 It is a structural schematic diagram of a film-based non-contact biological information collection device provided in an embodiment of the present application.

[0040] like Figure 1 As shown, the film-based non-contact biological information collection device specifically includes a collection device 100 and a film conveying device 200 .

[0041] The collection device 100 includes a collection surface 110. When the part to be identified of the user is located on the collection surface 110, the collection device 100 is used to collect biometric information of the part to be identified of the user.

[0042] The film conveying device 200 includes a film placing component 210, a film conveying component and a film recovery component 220. The film placing component 210 is used to place the film material, and the film conveying component is used to move the film material from the film placing component 210 to the film recovery component 220. When the film conveying component controls the film material to move from the film placing component 210 to the film recovery component 220, the film material continues to cover the collection surface 110, and the film recovery component 220 is used to place the film material passing through the collection surface 110.

[0043] like Figure 2 As shown, the film material 230 can be a continuous long strip of film, and the film material 230 is placed on the film placement component 210. At the initial moment, one end of the film material 230 can be pulled from the film placement component 210 to the film recovery component 220, and the end can be placed on the film recovery component 220. The film material 230 spans between the film placement component 210 and the film recovery component 220, and the film material 230 covers the collection surface 110 of the collection device 100. In subsequent use, the film transport component moves the film material 230 on the film placement component 210 to the film recovery component. During the movement, the film material 230 continues to cover the collection surface 110, and the film material passing through the collection surface 110 is recovered by the film recovery component 220.

[0044] The film material can be a thin, soft, transparent sheet, and the film material can be made of plastic, adhesive, rubber or other materials. The part to be identified is the part of the body used for biometric authentication. The biometric information of the part to be identified is collected, and biometric authentication is performed based on the biometric information to determine the user's identity information. The part to be identified includes the area from the finger, palm or wrist to the fingertip.

[0045] The collection device may be a collection device used to fit with the user's part to be identified to collect biometric information. In one embodiment, the collection device is a vein collection device. The part to be identified includes the finger, palm, or the area from the wrist to the fingertip. The area from the wrist to the fingertip may be the entire area from the wrist to the fingertip or a partial area from the wrist to the fingertip. The vein collection device can collect the user's vein characteristic information. The vein is hidden inside the body. Blood flows in the vein. The hemoglobin in the blood can absorb infrared light. Therefore, by irradiating infrared rays to the finger and shooting the part to be identified through the image collection unit, vein characteristic information showing the shape of the vein can be collected.

[0046] When the collection device needs to collect the biometric information of the part to be identified of the user, the part to be identified of the user does not need to directly contact the collection surface, but can be attached to the collection surface through the film material. When it is necessary to collect the biometric information of another user, the film conveying component can control the film material to move to replace the film material covering the collection surface, and the other user can also be attached to the collection surface through the replaced film.

[0047] The non-contact biometric information collection device based on a thin film provided in the embodiment of the present application can realize contactless collection of biometric information of the part to be identified of the user. Even if the collection device is used in an unrestricted population, there is no need to worry about the spread of bacteria due to the contact between the part to be identified of the user and the collection surface. The embodiment of the present application can reduce the spread of bacteria on the biometric information collection device and optimize the sanitary conditions.

[0048] In one embodiment, the non-contact biological information collection device based on thin film further comprises a processor, and the collection device and the thin film conveying component are both connected to the processor. The thin film conveying component can control the movement of the thin film material according to the situation collected by the collection device.

[0049] The processor is used to receive the biometric information sent by the acquisition device, and to determine whether the biometric information meets the preset verification conditions; if the biometric information meets the preset verification conditions, the film conveying component is controlled to operate so that the film material moves a preset distance from the film placement component to the film recovery component; if the biometric information does not meet the preset verification conditions, and the number of times the biometric information does not meet the preset verification conditions is greater than a preset number, the film conveying component is controlled to operate so that the film material moves a preset distance from the film placement component to the film recovery component.

[0050] The preset verification condition may be a condition for determining whether the biometric information sent by the acquisition device passes identity authentication. Exemplarily, the processor may determine whether the biometric information sent by the acquisition device meets the preset verification condition based on the pre-stored preset biometric characteristics, and the pre-stored preset biometric characteristics include biometric information of different preset users. If the biometric information sent by the acquisition device matches any of the preset biometric characteristics, it may be determined that the biometric information sent by the acquisition device meets the preset verification condition.

[0051] If the biometric information meets the preset conditions, it means that the current user has passed the identity authentication, and the user does not need to use the collection device in the short term, and the collection device may need to collect the biometric information of the next user, so the processor can control the film conveying component to work so that the film conveying component controls the film material to move from the film placement component to the film recovery component by a preset distance. The preset distance can be determined based on the length of the collection surface of the collection device, specifically, it can be determined based on the length of the collection surface in the direction of film material movement, and the preset distance can be greater than or equal to the length of the collection surface. For example, if the collection surface is a rectangle with a length of 3 cm and a width of 2 cm, and the film material moves along the length direction of the collection surface, the preset distance can be 3 cm or greater than 3 cm.

[0052] If the biometric information does not meet the preset verification conditions, it means that the current user has not passed the identity authentication. The failure to pass the identity authentication may be due to the low quality of the collected biometric information. The user can be prompted to collect the biometric information again. However, since the material of the film is relatively fragile, the film material may be damaged after multiple contacts. In this way, the user's to-be-identified part may be in direct contact with the collection surface, causing the bacteria on the to-be-identified part to spread to the collection surface. Therefore, when the biometric information does not meet the preset verification conditions, and the number of times the user's biometric information does not meet the preset verification conditions is greater than the preset number, the processor also controls the film transport component to work so that the film transport component controls the film material to move from the film placement component to the film recovery component by a preset distance. The specific value of the preset number of times can be determined according to the actual application situation and is not limited here.

[0053] Optionally, if the biometric information does not meet the preset verification conditions, and the number of times the biometric information does not meet the preset verification conditions within a preset time period is greater than a preset number, the film conveying component is controlled to operate so that the film material moves a preset distance from the film placing component to the film recovery component.

[0054] The processor may be a central processing unit (CPU), or other general-purpose processors, digital signal processors (DSP), application-specific integrated circuits (ASIC), field-programmable gate arrays (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor may be a microprocessor or any conventional processor, etc.

[0055] In one embodiment, the film placement assembly includes a first roller, the film recovery assembly includes a second roller, and the first roller and the second roller are used to wind the film material; the film transport assembly is used to control the rotation of the first roller and / or the second roller according to the rotation parameters.

[0056] The roller may be a component including a rotating shaft, and the roller may rotate as the rotating shaft rotates. The film placement component includes a first roller, and the unused film material may be wound on the first roller; the film recovery component includes a second roller, and the used film material passing through the collection surface may be wound on the second roller. If the second roller of the film recovery component rotates, the film material wound on the film recovery component will also rotate, and at the same time, the film material can drive the film material placed on the film placement component to rotate, thereby replacing the film material covering the collection surface.

[0057] The first roller of the film placement assembly and the second roller of the film recovery assembly can also rotate simultaneously, and the film material on the film placement assembly can also move to the film recovery assembly.

[0058] The film conveying assembly may include a control motor, which can drive the first roller and / or the second roller to rotate. The control motor can control the first roller and / or the second roller to rotate according to a rotation parameter so that the film material moves a preset distance from the film placing assembly to the film recovery assembly. The rotation parameter may include the number of rotations and the direction of rotation. For example, if the preset distance is 3 cm, and the roller rotates one circle to move the film material by 3 cm, the first roller and / or the second roller is controlled to rotate one circle.

[0059] In one embodiment, the film-based non-contact biological information collection device of the embodiment of the present application further includes a film material, and two ends of the film material are respectively wound around the first roller and the second roller.

[0060] In one embodiment, Figure 3 As shown, the film-based non-contact biometric information collection device further includes a placement member 300, the collection device 100 is arranged on a first plane of the placement member 300, and the first roller 210 and the second roller 220 are arranged on a second plane of the placement member 300. The first plane and the second plane may be the front and back sides of the placement member 300.

[0061] Optionally, the first roller 210 is fixed to the second plane of the placement member 300 by the first fixing member 310, the first fixing member 310 is fixed on the second plane of the placement member 300, one end of the rotating shaft of the first roller 210 is rotatably connected to the first fixing member 310, or both ends of the rotating shaft of the first roller 210 are rotatably connected to the first fixing member 310. Similarly, the second roller 220 is fixed to the second plane of the placement member 300 by the second fixing member 320, the second fixing member 320 is fixed on the second plane of the placement member 300, one end of the rotating shaft of the second roller 220 is rotatably connected to the second fixing member 320, or both ends of the rotating shaft of the second roller 220 are rotatably connected to the second fixing member 320.

[0062] The placement member 300 is provided with a first film channel 301 and a second film channel 302 for connecting the first plane and the second plane, and the first film channel 301 and the second film channel 302 are respectively located on both sides of the collection device 100; the first film channel 301 and the second film channel 302 can allow the film material to pass through, and when the film material 230 moves from the film placement component 210 to the film recovery component 220, it passes through the first film channel 301, the collection surface and the second film channel 302 in sequence.

[0063] The placement member may be a placement plate for fixing the collection device and the film conveying device. By placing the collection device and the film conveying device on different surfaces of the placement member, the volume of the non-contact biometric information collection device based on a film in the embodiment of the present application can be made smaller.

[0064] In one embodiment, Figure 4 and Figure 5 As shown, the film-based non-contact biometric information collection device further includes a rear cover 400, which forms a receiving space with the placement member 300, and the film conveying device is located in the receiving space, that is, the first roller and the second roller are both located in the receiving space.

[0065] The second plane of the placement member is also located in the accommodation space, and the first plane of the placement member is located outside the accommodation space.

[0066] The film material in the accommodation space can come out through the first film channel on the placement member and cover the collection surface of the collection device, then return to the accommodation space through the second film channel and be recovered by the film recovery component.

[0067] In one embodiment, the back cover is made of a transparent material, and the usage of the film material in the accommodating space can be checked through the back cover made of the transparent material, and the film material can be replaced when the film material is about to run out.

[0077] If the detected amount of film material meets the preset usage condition, it means that the film material on the film containing component is about to run out, and a usage alarm signal can be sent to the target end so that the management personnel can replace the film material.

[0078] In one embodiment, the film material is in contact with the collection surface, or there is a first distance between the film material and the collection surface.
