Description

Technical Field

[0001] The utility model relates to the technical field of book lending and returning, in particular to a book lending and returning device with a face recognition function. Background Art

[0002] Some large libraries, for example, are generally equipped with multiple book lending and returning devices in order to reduce the workload of the staff. The corresponding borrowers identify themselves on the book lending and returning devices through the borrowing cards and ID cards, and scan the books to be borrowed through the corresponding scanners. In order to ensure that the books in the library will not be lost after borrowing, the borrowers will apply for the corresponding borrowing cards before borrowing books. The borrowing cards represent the identity of the borrowers. When the books are lost, the identity of the borrowers will be quickly located. When the borrowers need to borrow books again, they need to return the previously borrowed books before they can borrow them again. However, this also faces some problems. When the borrower's borrowing card is lost, and the borrower is picked up by others and improperly used, a large number of books are borrowed and not returned. Eventually, the source is traced back to the borrower, which will cause a lot of unnecessary losses. In addition, some children may not be able to touch the scanning table when borrowing books, and if the scanning head is set too low, adults need to bend down frequently when using it, which is not convenient.

[0003] Based on the above problems, there is an urgent need for a library borrowing and returning device that can accurately identify the identity of the borrower and is convenient for children to borrow books. Utility Model Content

[0004] With respect to current book lending and returning devices, it is difficult to confirm the identity of the user and it is inconvenient for children to borrow books. The present application provides a book lending and returning device with a face recognition function to solve the above problems.

[0005] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0006] Optionally, an embodiment of the present application discloses a book lending and returning device with a facial recognition function, comprising a first scanning platform, the rear side of which is slidably connected to a fixed frame via a slide rail, a facial recognition screen is fixed above the fixed frame, and the fixed frame is driven by a motor to move up and down along the slide rail, a second scanning platform is arranged below the first scanning platform, a gravity sensor is arranged on the second scanning platform, a single-chip microcomputer is electrically connected between the gravity sensor and the motor, and when the gravity sensor senses gravity, the motor can be driven to control the descent of the fixed frame.

[0007] Optionally, the gravity sensed by the gravity sensor that drives the motor to move downward inside the single chip microcomputer is >80g.

[0008] Optionally, it also includes a touch display screen, which is used to display the name and quantity of the borrowed books.

[0009] Optionally, a first document recognition end and a first book scanning end are provided on the top surface of the first scanning platform.

[0010] Optionally, a second book scanning end is disposed on the bottom surface of the first scanning platform.

[0011] Optionally, a second document recognition terminal is disposed on the top surface of the second scanning platform.

[0012] Optionally, the gravity sensed by the gravity sensor that drives the motor to move upward inside the single chip microcomputer is less than 80g.

[0013] Optionally, the single chip microcomputer is also electrically connected to an alarm unit, and the alarm unit is used to alarm when the faces recognized by the first document recognition end and the second document recognition end are inconsistent with the faces recognized by the face recognition screen.

[0014] The beneficial effects of the utility model are:

[0015] 1. This application sets a face recognition screen above the book borrowing and returning device. When borrowing books, the borrower will scan the borrowing card or ID card. Each borrower and ID card corresponds to the borrower's facial information. Once someone borrows books using someone else's ID card, an error message will be displayed and the book cannot be borrowed.

[0016] 2. The present application has a second scanning platform below the first scanning platform. When children need to borrow books, they can place the books on the second scanning platform which is lower below. The corresponding gravity sensor and single-chip microcomputer jointly drive the fixed frame to descend, and drive the face recognition screen to descend, so as to scan and identify the child's face.

[0023] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0024] It should be understood that when used in the present specification and the appended claims, the term "comprising" indicates the presence of described features, wholes, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or combinations thereof.

[0025] See also Figure 1-Figure 3 To achieve the above purpose, the utility model is implemented through the following technical solutions:

[0026] For example, the original book lending device can generally only identify the corresponding borrower through the ID card. Once the borrower's ID card is lost and picked up and used by someone, it is easy for the book to be stolen by the picker, and the final traceability source is the borrower himself. In addition, the current lending device is difficult to be suitable for both children and adults. Based on the above problems, the embodiment of the present application discloses a book lending and returning device with a face recognition function, including a first scanning table 1, the rear side of the first scanning table 1 is slidably connected to a fixed frame 2 through a slide rail, a face recognition screen 3 is fixed above the fixed frame 2, and the fixed frame 2 is driven by a motor 4 to move up and down along the slide rail. A second scanning table 5 is arranged below the first scanning table 1, and a gravity sensor 6 is arranged on the second scanning table 5. A single-chip microcomputer 13 is electrically connected between the gravity sensor 6 and the motor 4. When the gravity sensor 6 senses gravity, the motor 4 can be driven to control the descent of the fixed frame 2. It is worth mentioning that the above-mentioned motor 4, single-chip microcomputer 13, gravity sensor 6 and face recognition screen 3 are all powered by the corresponding mains electricity. When children need to borrow books, they can place the books on the lower second scanning table 5. The gravity sensor 6 on the second scanning table 5 senses the weight, and the gravity sensor 6 will generate a current of corresponding size to the single-chip microcomputer 13 according to the weight. The single-chip microcomputer 13 determines that it is a book based on the received current and finally sends a control command to the motor 4. Click to drive the fixed frame 2 to descend, and the face recognition screen 3 also follows and descends to the second scanning table 5. The child’s face will be recognized and compared with the face corresponding to the borrowing certificate. After confirmation, the borrowing of books will begin.

[0027] By adopting the above technical solution, the gravity sensed by the gravity sensor 6 that drives the downward movement of the driving motor 4 arranged inside the single-chip computer 13 is >80g. When children need to borrow books, they can place the books on the second scanning table 5. This design can prevent children from accidentally touching the second scanning table 5 and causing the fixed frame 2 to accidentally descend, thereby wasting electricity.

[0028] It also includes a touch screen 7, which is used to display the name and quantity of the borrowed books. The borrower can confirm the scanned books and whether the scanned books correspond to the book titles through the touch screen 7, and confirm the books to be borrowed through the touch screen.

[0029] The top surface of the first scanning platform 1 is provided with a first document recognition terminal 8 and a first book scanning terminal 9. With the above technical solution, the first document recognition terminal 8 and the first book scanning terminal 9 on the scanning platform can respectively recognize documents and books, and the first document recognition terminal 8 is correspondingly connected to the face recognition screen 3 to obtain information from the two for discrimination, and similarly, the first book scanning terminal 9 is also correspondingly connected to the first book scanning terminal 9 to upload the scanned book to the touch screen for display.

[0030] The bottom surface of the first scanning platform 1 is provided with a second book scanning end 10. The design designs the first book scanning end 9 and the second book scanning end 10 on one scanning platform at the same time. The second book scanning end 10 irradiates downward to scan the books placed by the children on the second scanning platform 5.

[0031] The top surface of the second scanning platform 5 is provided with a second document recognition terminal 11. Children can place books on the second scanning platform 5 and can also place documents on the second scanning platform 5 for recognition and compare the facial information with the facial recognition screen 3 that is lowered.

[0032] The gravity sensor 6 that drives the upward movement of the driving motor 4 set inside the single chip computer 13 senses a gravity of <80g. When the child takes the scanned book off the second scanning platform 5, the gravity sensing device converts the current after identification and sends it to the single chip computer 13. The single chip computer 13 identifies and judges according to the current, and sends a control command to drive the fixed frame 2 to rise, so that the face recognition screen 3 rises to the height of the first scanning platform 1, so that the borrower whose height is greater than the scanning platform can be scanned. When the child needs to perform face recognition and book scanning, the book can still be placed on the second scanning platform 5 below. According to the method of the above embodiment, the fixed frame 2 is lowered again.

[0033] The single chip computer 13 is also electrically connected to an alarm unit 12, and the alarm unit 12 is used to alarm when the face recognized by the first document recognition terminal 8 and the second document recognition terminal 11 is inconsistent with the face recognition screen 3. With the above technical solution, when the borrower and the document do not correspond, an alarm will be issued, and the corresponding staff can come to find out the situation according to the alarm situation, and check whether it is a face recognition error or a mistake to use someone else's document.

[0034] Unless otherwise specified, the device components involved in the above embodiments are all conventional device components, and the connection methods and control methods involved are all conventional connection methods and control methods unless otherwise specified.

[0035] The present invention has been described in detail above in conjunction with the embodiments. However, those skilled in the art will appreciate that, without departing from the spirit of the present invention, the specific parameters in the embodiments described above may be changed to form a plurality of specific embodiments, which are all within the common variation range of the present invention and will not be described in detail herein.
