[0002] Smart access control is a new type of modern security management system, which integrates computer automatic identification technology and modern security management measures. It involves many new technologies such as electronics, mechanics, optics, computer technology, communication technology, biotechnology, etc. Smart access control has various ways to open the door, generally including finger vein identification, fingerprint recognition, face recognition and other methods.

[0003] Finger vein identification in existing smart access control systems is a biometric identification technology that is based on the principle that blood flowing in human fingers can absorb light of a specific wavelength. It uses a CCD camera to capture images of finger veins and stores these digital images in a computer system. Subsequently, feature values ​​are extracted from the finger vein distribution map based on a dedicated comparison algorithm and compared with the feature values ​​pre-stored in the computer to identify and confirm the individual.

[0004] In actual use, the finger vein recognition device is generally exposed behind the door handle of the smart access control. When using it, you only need to place your finger on it and wait for system authentication. However, long-term exposure of the recognition device to the outside usually leads to increasing dust on the contact surface of the recognition device, causing the dust to stick to the finger when the finger contacts the recognition device for authentication, greatly reducing the overall hygiene and safety factor. For this reason, the present application provides a finger vein identity recognition device based on smart access control. Utility Model Content

When the fingers are inserted into the protection frame 5, the cleaning component 6 will be driven to slide inside the protection frame 5. The sliding cleaning component 6 can quickly clean the dust on the surface of the finger vein identifier 3, and then you can place the finger on the finger vein identifier 3 for identification. After the identification is successful, you can open the door 1 to enter, so that the surface of the finger vein identifier 3 can be cleaned in time before each identity identification, reducing the situation of dust adhering to the fingers, and effectively improving the overall hygiene and safety of the device. When the cleaning component 6 needs to be replaced, the limit blockage of the cleaning component 6 can be released by pulling the limit component 7. At this time, the cleaning component 6 can be quickly replaced to keep the cleaning component 6 quiet and tidy. Secondly, in daily use, if the battery 4 is low on power and the finger vein identifier 3 cannot be used, the hidden plate 10 can be pulled to slide inside the hidden groove 8, thereby leaking the facial recognition device 9 inside the hidden groove 8. The facial recognition device 9 can be used to perform face recognition to open the door 1, so that the device as a whole has a certain emergency function, which effectively improves the practicability of the device.

At this time, the sliding plate 61 will be pushed to reset according to the rebound of the spring 1 64. The reset sliding plate 61 can drive the cleaning brush 63 to clean the surface of the finger vein identifier 3 again, and at the same time, it can also block external dust and reduce dust from entering the protective frame 5.

[0041] During use, after the face recognition by the facial recognition device 9 is completed, the hidden plate 10 can be pulled back to its original position. At this time, the position of the groove 101 will be in the same straight line as the limiting hole 11. The limiting block 103 will be driven into the limiting hole 11 according to the rebound of the spring three 102. In this way, the hidden plate 10 can be fixed in the hidden groove 8 through the cooperation between the limiting block 103 and the limiting hole 11.

When it is needed next time, just pull the hidden plate 10 to slide upwards. The limit with the limiting hole 11 can be quickly released according to the guidance of the arc-shaped end of the limiting block 103 to open the hidden plate 10.

[0042] The implementation principle of the finger vein identity recognition device based on smart access control in this embodiment is as follows: when it is necessary to open the door, the smart lock handle 2 can be held first, and then the middle finger and index finger can be inserted into the protection frame 5. When the fingers are inserted into the protection frame 5, the sliding plate 61 will be pushed to move along the direction of the slide groove 66 according to the guidance of the slider 65. When the sliding plate 61 moves, the cleaning brush 63 will be driven to move together. When passing through the finger vein identifier 3, the dust on the surface of the finger vein identifier 3 can be quickly cleaned by the cleaning brush 63, and then the finger can be placed on the finger vein identifier. The finger vein identifier 3 is identified, and after successful identification, the door 1 can be opened to enter, so that the surface of the finger vein identifier 3 can be cleaned in time before each identity identification, reducing the situation where dust adheres to the finger, effectively improving the overall hygiene and safety of the device. When the identification is completed, the finger can be pulled out, and the sliding plate 61 will be pushed to reset according to the rebound of the spring 1 64.

[0043] When the cleaning brush 63 needs to be replaced, the fixing plate 73 can be pulled to lift the two guide rods 72 upward, thereby driving the limiting plate 74 to move upward according to the guidance of the guide plate 76 and the direction of the guide groove 77 until the limiting plate 74 is away from one side of the sliding plate 61 after the sliding plate 61 loses the limiting interception of the limiting plate 74 and the elasticity of the spring 1 64 can push the sliding plate 61 to extend. At this time, the cleaning brush 63 can be quickly replaced, so as to keep the cleaning brush 63 clean and tidy. After the replacement is completed, the sliding plate 61 can be pushed into the protection frame 5 again, and then the fixing plate 73 is released, and the limiting plate 74 is reset according to the rebound of the spring 2 75, so that the position of the sliding plate 61 is limited and intercepted by the limiting plate 74 after the reset, so that the position of the sliding plate 61 can be stabilized in the protection frame 5.

[0044] Secondly, in daily use, if the battery 4 is low on power and the finger vein identifier 3 cannot be used, the hidden plate 10 can be pulled to slide inside the hidden groove 8, thereby exposing the facial recognition device 9 inside the hidden groove 8. The facial recognition device 9 can be used to perform face recognition and open the door 1, so that the device as a whole has a certain emergency function, which effectively improves the practicality of the device. After the facial recognition is completed using the facial recognition device 9, the hidden plate 10 can be pulled back to reset, and the position of the groove 101 will be in the same position as the limit hole 11. In a straight line, according to the rebound of spring three 102, the limit block 103 will be driven to enter the limit hole 11, so that the hidden plate 10 can be fixed in the hidden groove 8 through the cooperation of the limit block 103 and the limit hole 11. The hidden plate 10 can effectively reduce the dust from entering the hidden groove 8 to avoid affecting the recognition effect of the facial recognition device 9. When it is needed next time, you only need to pull the hidden plate 10 to slide upwards, and according to the guidance of the arc end of the limit block 103, you can quickly release the limit with the limit hole 11 to open the hidden plate 10.
