Description

Technical Field

[0001] The present invention relates to the technical field of vein verification, and in particular to a computer-based vein verification device. Background Art

[0002] Finger vein recognition technology is based on the property that the blood flowing in human fingers absorbs light of specific wavelengths. By using near-infrared light to illuminate the fingers, the finger can be identified based on the absorption of near-infrared light by hemoglobin. However, existing finger vein verification devices are embedded in door locks, mice and other products and must be used in specific scenarios. There is no product that can be directly connected to other devices and used in combination with other devices to achieve the function of identity authentication. The finger vein verifier uses a single-sided light source to illuminate the knuckles of the fingers, and then uses a detection head set on the opposite side of the light source to capture the image of the finger veins. However, the image of the finger veins captured in this way is not clear, which affects the accuracy of the verification. At the same time, most of the existing finger vein verifiers are fixedly connected, and the height cannot be adjusted according to the needs of use. The flexibility of use is poor, and there is a lack of protective devices, which can easily cause damage and shorten the service life.

[0003] Therefore, there is a need for a computer-based vein verification device that can illuminate the finger veins with a bidirectional light source to improve the clarity of finger vein photography, and then facilitate later connection with a computer to improve ease of use. The device can also adjust the height of use according to usage requirements, has good flexibility of use, and has a protective device to reduce damage and increase the service life. Summary of the invention

[0004] The purpose of the present invention is to provide a computer-based vein verification device, which aims to improve the existing finger vein verification device that is embedded in door locks, mice and other products and must be used in specific scenarios. There is no product that can be directly connected to other devices, that is, used in combination with other devices to achieve the function of identity authentication. The finger vein verifier uses a single-sided light source to illuminate the knuckles of the fingers, and then captures the image of the finger veins through a detection head arranged on the opposite side of the light source. However, the image of the finger veins captured in this way is not clear, which affects the accuracy of the verification.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) When the computer-based vein verification device is used for finger vein verification, the vein fingerprint of the person to be verified needs to be stored in the processor in the electromechanical box before use. When using the verification, the finger vein of the verifier is placed in the finger groove of the base, and the finger vein is illuminated by the light source lamps arranged relatively in the upper lamp holder and the inside of the finger groove, so that the finger vein pattern is clearly displayed. Then, after being photographed by the shooting module in the base, an electrical signal is transmitted to the connecting line through the slot of the base, and then connected to the connecting slot of the box body through the connecting line, and the electrical signal is transmitted to the processor by the cable. The processor compares the data with the stored data. If the data is the same as the stored data, the processor sends a signal through the signal. The signal is transmitted to the controller through the cable, and the controller controls the first warning light to light up, indicating that it has passed. On the contrary, when the cable transmits the electrical signal to the processor, the processor compares the data with the stored data. If the data is different from the stored data, the processor sends a pass signal to the controller through the cable, and the controller controls the second warning light to light up, indicating that it has failed.

Then, the slider of the frame sleeve is used to slide with the sliding groove on the base for easy assembly, and suction cups are evenly bonded to the bottom surface of the frame sleeve to facilitate adsorption installation and improve the stability of installation.

[0019] (3) In order to facilitate installation and flexible use in the future, the present invention has a slide plate symmetrically and horizontally welded on the left and right side end surfaces of the card frame seat, and a slide frame is horizontally slidably installed on the slide plate.

The controller 54 controls the first warning light 55 or the second warning light 56 ​​to light up to indicate whether it has passed.

[0053] Working principle: When the computer-based vein verification device is used for finger vein verification, the vein fingerprint of the person to be verified needs to be stored in the processor 53 in the electromechanical box 5 before use. When using the verification, the finger vein of the verifier is placed in the finger groove 13 of the base 11, and the upper lamp holder 12 and the light source lamp 14 arranged relatively inside the finger groove 13 are used to illuminate the finger vein, so that the finger vein pattern is clearly displayed. Then, after being photographed by the shooting module in the base 11, the electrical signal is transmitted to the connecting wire 3 through the slot port 18 of the base 11, and then connected to the connecting slot 52 of the box body 51 through the connecting wire 3, and the cable is used to connect the connecting wire 3 to the connecting slot 52 of the box body 51. The electrical signal is transmitted to the processor 53, and compared with the stored data by the processor 53. If the data is the same as the stored data, the processor 53 sends a pass signal to the controller 54 through the cable. The controller 54 controls the first warning light 55 to light up, indicating a pass. On the contrary, when the cable transmits the electrical signal to the processor 53, and compares with the stored data by the processor 53, if the data is different from the stored data, the processor 53 sends a pass signal to the controller 54 through the cable. The controller 54 controls the second warning light 56 ​​to light up, indicating a fail, thereby completing the verification requirement.

[0054] The device obtained through the above design can basically meet the use of a computer-based vein verification device that can provide bidirectional light source illumination to the finger veins, thereby improving the clarity of finger vein photography, and then facilitate subsequent connection with a computer to improve the convenience of use. However, in order to further improve its functions, the designer has further improved the device.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
