Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of library turnstiles, and particularly relates to a multi-channel parallel ultra-high frequency passive borrowing and returning channel. Background Art
[0002] The passive borrowing and returning channel is a modern library service facility. It usually adopts radio frequency identification (RFID) or other advanced technical means, which can automatically read the labels or coding information on books without manual scanning one by one. The RFID tags are embedded in the books. When the books pass through the channel, the system can quickly obtain the relevant information. Readers only need to put the books to be borrowed or returned into the designated area, and the system can automatically complete the registration and processing, greatly saving time. In a busy library, readers can complete the borrowing and returning operations of multiple books in a short time and reduce queuing waiting.
[0003] However, when dealing with books with damaged or faulty tags, the RFID tags on these books are damaged, worn, or there are internal circuit failures, resulting in inaccurate identification. During long-term use, the tags are scratched and folded, affecting signal transmission. At this time, when borrowers borrow or return books through the passive borrowing and returning channel, the phenomenon of unidentifiable may occur, leading to incorrect book information. When such a situation occurs, the prior art usually reminds through a display screen. However, although such a reminder method can remind borrowers to handle it, when encountering such accidental phenomena, borrowers usually don't know what to do and need to spend a lot of time communicating and dealing with it, which affects the borrowing and returning efficiency of the passive borrowing and returning channel for books.
[0004] Therefore, we propose a multi-channel parallel ultra-high frequency passive borrowing and returning channel. Content of the Utility Model
[0005] The purpose of the utility model is to provide a multi-channel parallel ultra-high frequency passive borrowing and returning channel to solve the problems raised in the above background art.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A multi-channel parallel ultra-high frequency passive borrowing and returning channel, including a control box body. Multiple channels are arranged side by side on the control box body. Each channel is used for borrowers to borrow or return books. Multiple identification and judgment components are arranged on both sides of each channel. Each identification and judgment component includes multiple ultra-high frequency antennas and sensors. The multiple ultra-high frequency antennas are used to sense the ultra-high frequency chips in the books, and the multiple sensors are used to sense the positions of the borrowers.
[0007] And a reminder component. The reminder component includes a display screen and multiple speakers. The display screen is arranged beside the channel, and the multiple speakers are arranged at intervals on both sides of the channel.
[0008] Through the above technical solution, by setting up an identification and judgment component and multiple UHF antennas in the identification and judgment component, the signal coverage range can be enhanced. More UHF antennas can make the signal coverage more comprehensive and reduce signal dead spots, thereby improving the reading ability of UHF chips in books in different positions. For example, UHF chips that were originally in certain corners or special angles are difficult to be identified. After adding UHF antennas, the probability of being effectively read can be increased, thereby fundamentally improving the recognition rate of books and reducing the probability of errors. When the phenomenon of unrecognition occurs, in addition to reminders through the display screen, the erroneous information can also be voice broadcast through multiple speakers, so that borrowers and staff can be reminded at the same time, thereby saving communication and processing time to improve the efficiency of borrowing and returning books.
[0009] Furthermore, an exit swing gate and an entrance swing gate are respectively provided at both ends of each channel.
[0010] Furthermore, a facial recognition integrated machine is installed at both ends of each channel.
[0011] Furthermore, card swiping and code scanning machines are provided at both ends of each channel.
[0012] Through the above technical solution, the identity of the borrower can be verified by facial recognition through an all-in-one facial recognition machine, or by swiping a card or scanning a code through a card swiping or code scanning machine. There are various verification methods, and borrowers can choose according to actual conditions. After the identity verification is passed, the exit swing gate and the entrance swing gate will automatically open, realizing the function of seamless borrowing books when leaving the library.
[0013] Furthermore, a control main board is arranged in the control box, and an ultra-high radio frequency board is arranged on the control main board.
[0014] Furthermore, a plurality of UHF antennas are spaced apart on the channel, and each UHF antenna is electrically connected to the UHF board.
[0015] Through the above technical solution, the UHF RF board generates electrical signals of specific frequency and power. These signals are transmitted to multiple UHF antennas. The UHF antennas radiate the electrical signals to the surrounding space in the form of electromagnetic waves, forming an electromagnetic field. When a book with an UHF chip enters this electromagnetic field, the UHF chip will reflect back electromagnetic waves with specific information. The UHF antenna receives these reflected waves and converts them into electrical signals and transmits them back to the RF board. The RF board processes and demodulates these returned signals, extracts the information in the UHF chip, and thus realizes the identification and reading of the book information corresponding to the UHF chip.
[0016] Furthermore, decorative light panels are provided at both ends of each channel.
[0017] Through the above technical solution, the decorative light board can display some decorative information and improve the decorative effect.
[0018] Further, multiple sensors are spaced apart on the passage, and each sensor is electrically connected to the control main board.
[0019] Further, the reminder component further includes multiple atmosphere light belts, and the multiple atmosphere light belts are spaced and arranged on both sides of the passage.
[0020] Through the above technical solution, when an unrecognizable phenomenon occurs, in addition to reminding the wrong information through the display screen and the speaker, different colors of lights can also be displayed through the atmosphere lights, so as to more effectively remind the borrowers and the staff at the same time, thus saving the communication processing time and improving the borrowing and returning efficiency of books.
[0021] Further, the control main board is used to control the opening and closing of the exit swing gate and the entrance swing gate.
[0022] Compared with the prior art, the beneficial effects of the present utility model are:
[0023] First, in the present utility model, by setting the recognition and judgment component and multiple ultra-high frequency antennas in the recognition and judgment component, the signal coverage range can be enhanced. More ultra-high frequency antennas can make the signal coverage more comprehensive and reduce signal dead corners, thereby improving the reading ability of the ultra-high frequency chips in books at different positions. For example, the ultra-high frequency chips in some corners or special angles were originally difficult to be recognized, and the probability of being effectively read can be increased after adding ultra-high frequency antennas, so as to improve the recognition rate of books from the root cause and reduce the probability of errors. And when an unrecognizable phenomenon occurs, in addition to reminding through the display screen, multiple speakers can also be used to perform voice broadcasts on the wrong information, so as to remind the borrowers and the staff at the same time, thus saving the communication processing time and improving the borrowing and returning efficiency of books.
[0024] Second, multiple channels are arranged in parallel on the control box body of the present utility model, and by parallelizing these channels, the problems of multi-channel frequency hopping and missed reading, and mutual interference between multi-channels are solved. Compared with the traditional single-channel passive borrowing channel, the problem that the entrance and exit of the flow of people is small and only one person can pass through at a time is solved, and the borrowing efficiency is higher.

Specific implementation manners
[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0032] Please refer to Figures 1 - 5 , a multi-channel parallel ultra-high frequency non-contact borrowing channel, including a control box 1, on which a plurality of channels 2 are arranged in parallel. Each channel 2 is used for borrowers to borrow or return books. On both sides of each channel 2, a plurality of identification and judgment components are arranged. Each identification and judgment component includes a plurality of ultra-high frequency antennas 12 and an inductor 14. The plurality of ultra-high frequency antennas 12 are used to sense the ultra-high frequency chips in the books, and the plurality of inductors 14 are used to sense the position of the borrowers;
[0033] And a reminder component, the reminder component includes a display screen 5 and a plurality of speakers 10. The display screen 5 is arranged beside the channel 2, and the plurality of speakers 10 are arranged at intervals on both sides of the channel 2.
[0034] In the present utility model, by providing an identification and judgment component and a plurality of ultra-high frequency antennas 12 in the identification and judgment component, the signal coverage range can be enhanced. More ultra-high frequency antennas 12 can make the signal coverage more comprehensive, reducing signal dead zones, thereby improving the reading ability of ultra-high frequency chips in books at different positions. For example, ultra-high frequency chips in certain corners or at special angles were originally difficult to identify, but increasing the ultra-high frequency antennas 12 can increase the probability of effective reading, thus fundamentally improving the recognition rate of books and reducing the probability of errors. Moreover, when an unidentifiable phenomenon occurs, in addition to being reminded through the display screen 5, a plurality of speakers 10 can also be used to perform voice broadcast of error information, thereby simultaneously reminding borrowers and staff, thus saving the time for communication and processing to improve the borrowing and returning efficiency of books.
[0035] Please refer to Figures 1 - 3 , at both ends of each passage 2, an exit turnstile 3 and an entrance turnstile 4 are respectively provided. At both ends of each passage 2, a face recognition integrated machine 6 is provided, and at both ends of each passage 2, a card swiping and code scanning machine 9 is provided.
[0036] Through such a setting method, the identity of borrowers can be verified by face recognition through the face recognition integrated machine 6, or the identity of borrowers can also be verified by swiping a card or scanning a code through the card swiping and code scanning machine 9. The verification methods are diverse, and borrowers can choose according to the actual situation. After the identity verification is passed, the exit turnstile 3 and the entrance turnstile 4 will automatically open to realize the function of borrowing books without feeling in the library.
[0037] Please refer to Figures 3 - 5 , a control main board 7 is provided in the control box body 1. An ultra-high frequency board 8 is provided on the control main board 7. The multiple ultra-high frequency antennas 12 are spaced apart on the passage 2, and each ultra-high frequency antenna 12 is electrically connected to the ultra-high frequency board 8.
[0038] It should be noted that the ultra-high frequency board generates electrical signals with specific frequencies and powers. These signals are transmitted to the multiple ultra-high frequency antennas 12. The ultra-high frequency antennas 12 radiate the electrical signals into the surrounding space in the form of electromagnetic waves to form an electromagnetic field. When a book with an ultra-high frequency chip enters this electromagnetic field, the ultra-high frequency chip will reflect electromagnetic waves with specific information. The ultra-high frequency antennas 12 receive these reflected waves and convert them into electrical signals and transmit them back to the radio frequency board. The radio frequency board processes and demodulates these returned signals to extract the information in the ultra-high frequency chip, thereby realizing the identification and reading of the book information corresponding to the ultra-high frequency chip.
[0039] It is worth mentioning that multiple channels 2 are arranged in parallel on the control box body 1 of the present utility model, and all the multiple channels 2 are uniformly controlled by the control main board 7. By parallelizing these channels 2, problems such as multi-channel crosstalk and missed reading are solved, and the signals between the multiple channels 2 will not interfere with each other. Compared with the traditional single-channel passive borrowing channel, the problem that the entrance and exit of the flow of people is small and only one person can pass through at a time is solved, and the borrowing efficiency is higher.
[0040] Please refer to Figure 3 , decorative lamp boards 11 are arranged at both ends of each channel 2. The decorative lamp boards 11 can display some decorative information to improve the decorative effect. For example, information such as "Welcome" and "Happy New Year" can be displayed.
[0041] Please refer to Figures 3 - 5 , multiple sensors 14 are distributed at intervals on the channel 2, and each sensor 14 is electrically connected to the control main board 7. The reminder component further includes multiple atmosphere light belts 13. The multiple atmosphere light belts 13 are arranged at intervals on both sides of the channel 2. The control main board 7 is used to control the opening and closing of the exit swing gate 3 and the entrance swing gate 4.
[0042] It is worth mentioning that when an unrecognizable phenomenon occurs, in addition to reminding the error information through the display screen 5 and the speaker 10, different colors of lights can also be displayed through the atmosphere lights, so that borrowers and staff can be reminded more effectively at the same time, thus saving the time for communication and processing and improving the borrowing and returning efficiency of books.
[0043] The basic principle of this passive borrowing channel 2 is as follows: when a borrower borrows a book, the sensor 14 near the entrance swing gate 4 senses the approach of a person, and starts the ultra-high frequency antenna 12 near the entrance swing gate 4 to scan the book. The borrower passes through three verification methods: face recognition, card swiping or code scanning. After the verification is completed, the entrance swing gate 4 opens. Then, multiple ultra-high frequency antennas 12 are turned on simultaneously to scan the book information carried by the borrower; the display screen 5 synchronously displays the scanning result. After the borrower determines the corresponding operation and the verification is completed, it is determined whether to open the exit swing gate 3.
[0044] When the borrower returns a book, the sensor 14 near the exit swing gate 3 senses the approach of a person, and starts the ultra-high frequency antenna 12 near the exit swing gate 3 to scan the book. The borrower passes through three verification methods: face recognition, card swiping or code scanning. After the verification is completed, the exit swing gate 3 opens. Then, multiple ultra-high frequency antennas 12 are turned on simultaneously to scan the book information carried by the borrower, and the display screen 5 synchronously displays the scanning result. After the borrower determines the corresponding book return operation and the verification is completed, it is determined whether to open the entrance swing gate 4.
[0045] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising" - "including" or any other variant thereof is intended to cover non-exclusively, so that a process - method - article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process - method - article or device.
[0046] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model.
