Description

Technical Field

[0001] The present invention relates to the field of finger vein collection, and in particular to a method for using a light debugging device for finger vein irradiation. Background Art

[0002] With the development of industrial technology, modern finger vein collection equipment has become more and more sophisticated. Finger vein recognition has been applied to electronic lock systems. Compared with fingerprint recognition technology, finger vein collection requires light to penetrate the person's finger, and the color depth of each person's skin is different. Some people have darker skin and muscle tissue, while others have lighter skin. Furthermore, fingers vary in thickness. Those with thicker fingers are less likely to be penetrated by light, but strong light that hits the finger veins of fair skin can also affect line collection. After the collection screen is pressed by fingers many times, a lot of dust will accumulate. When the dust accumulates to a certain extent, it will affect the collection of finger vein patterns. Summary of the Invention

[0003] The purpose of the present invention is to address the deficiencies of the existing technology and provide a method for using a light debugging device for finger vein irradiation. When the device is in use, a person's finger is pressed on the acquisition screen in the middle of the acquisition frame. The acquisition frame identifies the color depth of the person's skin and muscle tissue based on the ambiguity of the acquisition, and twists the circular frame to select which curved groove is facing the position of the irradiation acquisition frame. The stronger light can penetrate the fingers of people with dark skin, thereby achieving an automatic debugging effect.

[0004] To solve the above problems, the present invention provides the following technical solutions: a light debugging device for finger vein irradiation, comprising a mounting frame, an extension plate provided at the top of the mounting frame, the mounting frame and the extension plate being integrally formed, an outer wall of the mounting frame being provided with a collection frame, a keypad and a whistle, a pendant block provided at the front end of the extension plate, a servo motor provided at the top of the pendant block, and a torsion circular frame provided on the inner side of the pendant block, the output rod of the servo motor passing through the pendant block and connected to the torsion circular frame, a strip light provided on the inner side of the torsion circular frame, four curved grooves provided on the outer wall of the torsion circular frame, filter glasses provided on the inner side of the curved grooves, and one to four layers of color films attached to the four filter glasses respectively, two black light-blocking flanges provided on the side of the pendant block facing the mounting frame, a detachable cover provided on the side of the pendant block facing away from the mounting frame, a accommodating cavity provided on the back side of the mounting frame, an instrument replacement assembly and a cleaning liquid supply assembly provided on the inner side of the accommodating cavity.

[0005] Furthermore, an inclined collection screen is provided on the inner side of the collection frame, and an air jet and an atomizing nozzle are provided on the top of the collection screen.

[0006] Furthermore, the whistle is provided with a buzzer and a camera, and the camera is connected to the client terminal via mobile data.

[0007] Furthermore, the instrument exchange assembly includes an exchange guide rail, which is fixed on the inner wall of the accommodating cavity. Two exchange slides are slidably installed on the exchange guide rail. The exchange slides are connected by a connecting bridge, and a support plate is provided on one side of the two exchange slides. The fingerprint collector and the finger vein collector can be detachably installed on the support plate. The top exchange slide is installed on the output end of the electric push rod.

[0008] Furthermore, the cleaning liquid supply assembly includes an alcohol tank, which is fixed on the inner wall of the accommodating cavity. A water pump is provided on one side of the alcohol tank. The output pipe of the water pump is connected to the atomizing nozzle, and the nozzle is connected to the air machine, which is arranged on the outside of the mounting frame.

[0009] Furthermore, the keypad is a password input terminal. After the keypad is entered four times, the buzzer on the horn will be triggered and information will be sent to the mobile phone terminal. The camera on the horn will also take a photo and send it to the mobile phone terminal. After the client sees the photo of the person, the key will be automatically opened through the mobile phone operation. Secondly, for outsiders, the face photo can be directly collected and sent to the mobile phone terminal, and then manually unlocked.

[0010] Furthermore, the acquisition framework pre-collects the finger vein patterns and fingerprints of the person as a comparison library, and the acquisition framework collects the finger vein patterns for comparison, and the key is unlocked when the contrast reaches 95%.

[0011] Furthermore, the servo motor drives the torsional circular frame to rotate ninety degrees each time so that each curved slot reaches the irradiation position. When the finger vein patterns collected by the collection frame are unclear, the torsional circular frame is turned to the curved slot with less light blocking, allowing more light to be dispersed. The stronger light passing through the finger of the person on the collection frame makes it easier to show the finger veins.

[0012] Further, the following steps are included: S1. The person's finger presses on the capture screen in the center of the capture frame. The capture frame identifies the color depth of the person's skin and muscle tissue based on the image's ambiguity. The circular frame is twisted to select which curved slot faces the capture frame. This provides stronger light that can penetrate dark-skinned fingers. S2. Drive the shifting slider to move the two units back and forth, so that the fingerprint collector and finger vein collector rotate to the position behind the collection screen. The device can then collect fingerprints and finger veins, and the device can be adjusted according to actual needs; S3. After the punch-in time period ends, the water pump extracts the liquid inside the alcohol tank and flushes it into the atomizing nozzle. The atomizing nozzle flushes the collection screen. After the flushing is completed, the air machine flushes out high-pressure air through the nozzle to clean the collection screen.

[0013] Beneficial effects of the present invention: First, when the device is in use, the person's finger presses on the acquisition screen in the middle of the acquisition frame. The acquisition frame identifies the color depth of the person's skin and muscle tissue based on the acquisition ambiguity, and twists the circular frame to select which curved slot is facing the position of the irradiation acquisition frame. The stronger light can penetrate the fingers of people with dark skin, achieving the effect of automatic debugging.

[0014] Secondly, the drive shift slider moves the two units' workstations back and forth, and then the fingerprint collector and finger vein collector will rotate to the position behind the collection screen. Then the device can collect fingerprints and finger veins, and adjust the device according to actual needs, achieving a multi-functional adjustment effect.

[0015] Third, after the punch-in time period ends, the water pump draws the liquid inside the alcohol tank into the atomizing nozzle, and the atomizing nozzle flushes the collection screen. After the flushing is completed, the air machine flushes out high-pressure air through the nozzle to clean the collection screen, thereby achieving the effect of cleaning accumulated dust.

The back side of the mounting frame 1 is provided with a accommodating cavity 9, and the inner side of the accommodating cavity 9 is provided with an instrument replacement component and a cleaning liquid supply component. The person's fingers are pressed on the acquisition screen 601 in the middle of the acquisition frame 6. The acquisition frame 6 identifies the color depth of the person's skin and muscle tissue according to the ambiguity of the acquisition. The twisting circular frame 5 is rotated to select which curved groove 501 is facing the position of the irradiation acquisition frame 6. The stronger light can penetrate the fingers of people with dark skin.

[0026] An inclined collection screen 601 is provided on the inner side of the collection frame 6, and a nozzle 602 and an atomizing nozzle 603 are provided on the top of the collection screen 601. The atomizing nozzle 603 sprays a little water mist toward the collection screen 601, and then the nozzle 602 outputs high-pressure air to blow dry the collection screen 601, thereby achieving the effect of automatically cleaning the screen.

[0027] The whistle 8 is provided with a buzzer and a camera. The camera is connected to the client terminal via mobile data. The keypad 7 is a password input terminal. After the keypad is input four times, the buzzer on the whistle 8 is triggered and information is sent to the mobile phone terminal. The camera on the whistle 8 will also take a photo and send it to the mobile phone terminal. After the client sees the photo, the key can be automatically opened through the mobile phone operation.

[0028] The instrument exchange assembly includes an exchange guide rail 10, which is fixed on the inner wall of the accommodating chamber 9.

Then the air machine rushes out high-pressure air through the jet head 602 to blow the collection screen 601 dry.

[0030] The keypad 7 is a password input terminal. After the keypad 7 is input four times, the buzzer on the whistle 8 is triggered and information is sent to the mobile phone terminal. The camera on the whistle 8 will also take a photo and send it to the mobile phone terminal. If the identification fails, the client personnel will see the person's photo and automatically open the key through the mobile phone operation. Secondly, for outsiders, the face photo can be directly collected and sent to the mobile phone terminal, and then manually unlocked. If the device recognition cannot be performed, manual identification is performed by taking a photo. After confirming that it is the corresponding person, the key is manually opened.

[0031] The collection framework 6 collects the finger vein patterns and fingerprints of the person in advance as a comparison library. The collection framework 6 collects the finger vein patterns for comparison. The key is unlocked when the contrast reaches 95%. The comparison library can collect the finger veins of two fingers in advance for storage. If the difference of one finger cannot reach 95%, the other finger is used for collection and identification.

[0032] The servo motor 4 drives the torsion frame 5 to rotate ninety degrees each time so that each curved groove 501 reaches the irradiation position. When the finger vein patterns collected by the collection frame 6 are unclear, the torsion frame 5 is turned to the curved groove 501 with less light blocking, allowing more light to be dispersed. Stronger light passing through the finger of the person on the collection frame 6 makes it easier to show the finger veins. The filter degree is adjusted according to the depth of the human tissue color. For people with white skin, a filter glass with stronger filter light is replaced, and for people with dark skin, a filter glass with weaker filter light is replaced.

[0033] The following steps are involved: S1. The person's finger presses on the capture screen 601 in the center of the capture frame 6. The capture frame 6 identifies the color depth of the person's skin and muscle tissue based on the acquired blur. The twisting frame 5 rotates to select which curved slot 501 faces the capture frame 6. This provides stronger light that can penetrate dark-skinned fingers. S2.1006 drives the shifting slider 1001 to move back and forth between two workstations, so that the fingerprint collector 1004 and the finger vein collector 1005 rotate to the position behind the collection screen 601. The device can then collect fingerprints and finger veins, and the device can be adjusted according to actual needs. S3. After the punch-in time period ends, the water pump 1101 extracts the liquid inside the alcohol tank 11 and flushes it into the atomizing nozzle 603. The atomizing nozzle 603 flushes the collection screen 601. After the flushing is completed, the air machine flushes out high-pressure air through the nozzle 602 to clean the collection screen 601.

[0034] Working principle: The person's finger presses on the collection screen 601 in the middle of the collection frame 6. The collection frame 6 identifies the color depth of the person's skin and muscle tissue based on the ambiguity of the collection. The twisted circular frame 5 is rotated to select which curved groove 501 is facing the position of the irradiation collection frame 6. The stronger light can penetrate the fingers of people with dark skin. The atomizing nozzle 603 sprays a little water mist towards the collection screen 601, and then the nozzle 602 outputs high-pressure air to blow dry the collection screen 601, achieving the effect of automatically cleaning the screen. The keypad 7 is the password input terminal. After the keypad is entered four times, the buzzer on the horn 8 is triggered and information is sent to the mobile phone terminal. The forehead camera on the horn 8 will also take a photo and send it to the mobile phone terminal. After the client sees the person's photo, the key is automatically opened through the mobile phone operation. The electric push rod 1006 drives the repositioning slider 1001 to move back and forth between the two units' workstations, and then the fingerprint collector 1004 and the finger vein collector 1005 will rotate to reach the collection screen. The device is located behind the screen 601, and can collect fingerprints and finger veins. The device can be adjusted according to actual needs. The water pump 1101 draws alcohol cleaning liquid from the alcohol tank 11 and sprays it from the atomizing nozzle 603 to clean the collection screen 601. Then the air machine blows out high-pressure air through the nozzle 602 to dry the collection screen 601. If recognition is unsuccessful, the client staff will see the person's photo and automatically open the key through the mobile phone. Secondly, for outsiders, a face photo can be directly collected and sent to the mobile terminal, and then manually unlocked. If device recognition is unsuccessful, manual recognition is performed by taking a photo. Once the corresponding person is confirmed, the key is manually opened. The comparison library can collect the finger veins of two fingers in advance for storage. If the difference of one finger cannot reach 95%, the other finger will be replaced for collection and recognition. The filter degree is adjusted according to the depth of human tissue color. For white-skinned people, a stronger filter glass is replaced, and for dark-skinned people, a weaker filter glass is replaced.
