Abstract
Description
Technical Field
[0001] This invention relates to the field of automation technology, specifically to a dual-frequency book return machine for libraries. Background Technology
[0002] Traditional book return machines typically return books with only one type of RFID tag. For libraries that return books with both high-frequency and ultra-high-frequency tags, two sets of equipment need to be purchased, which is costly, and readers need to find the corresponding equipment when returning books.
[0003] Defects and shortcomings of existing technology:
[0004] 1. Existing book return machines can only return books with a single RFID tag, which cannot handle the return of books in the library that have both high-frequency tags and ultra-high-frequency tags;
[0005] 2. UHF book return machines located close to each other may perform overflow scanning on books being returned to each other, causing readers to fail to return their books;
[0006] 3. When returning books, readers need to find the corresponding return equipment, as using it may result in poor performance. Utility Model Content
[0007] To address the technical problem that traditional book return machines cannot simultaneously recognize books with high-frequency and ultra-high-frequency tags, this application proposes a dual-frequency book return machine for libraries, which solves the aforementioned technical problem.
[0008] The technical solution adopted by this utility model to solve its technical problem is:
[0009] This utility model provides a dual-frequency book return machine for libraries, comprising: a frame, wherein a book return channel is configured within the frame, the book return channel forming a book return opening on one side of the frame, and a flow strip being configured on the opposite side of the frame; an ultra-high frequency antenna, wherein the ultra-high frequency antenna is configured at the top of the book return channel; and a dual-frequency antenna box, wherein the dual-frequency antenna box is configured at the bottom of the book return channel. The ultra-high frequency antenna at the top and the ultra-high frequency antenna in the dual-frequency antenna box at the bottom simultaneously read the ultra-high frequency tags of the books, and the reading results are mutually verified to reduce misreading caused by ultra-high frequency antenna overflow. At the same time, the high frequency antenna in the dual-frequency antenna box reads the high frequency RFID tags of the books.
[0010] Furthermore, the shelf is equipped with an audio-visual prompting component above the book return slot. The audio-visual prompting component includes an indicator light and a prompting speaker to indicate to the reader whether the book has been successfully returned.
[0011] Furthermore, the shelf is equipped with a touchless switch above the book return opening, which controls the opening and closing of the cover door at the book return opening by waving a hand.
[0012] Furthermore, the shelf is equipped with an anti-pinch detection light curtain at the book return opening to detect whether any foreign objects enter the book return opening.
[0013] Furthermore, a display screen is provided on the top of the shelf to show information about the returned books.
[0014] Furthermore, the book return channel is equipped with a conveyor belt that can rotate in both directions to facilitate the return or removal of books.
[0015] Furthermore, the dual-band antenna box is configured within the frame via a slide rail assembly.
[0016] Furthermore, the frame is also equipped with a high-frequency reader / writer, an ultra-high-frequency reader / writer, and an air switch. The high-frequency reader / writer is connected to the dual-frequency antenna box via an RF cable, and the ultra-high-frequency reader / writer is connected to both the dual-frequency antenna box and the ultra-high-frequency antenna via an RF cable. The air switch is used for the safety of the entire circuit.
[0017] Furthermore, the frame is also equipped with an electrical control box and a cooling fan for thermal interaction with the electrical control box.
[0018] Furthermore, the bottom of the frame is equipped with FOM casters.
[0019] Based on the above technical solution, the technical effects that this utility model can achieve are as follows:
[0020] This utility model discloses a dual-frequency book return machine for libraries. The machine has a book return channel within its frame. An ultra-high frequency (UHF) antenna is positioned at the top of the return channel, and a dual-frequency antenna box is positioned at the bottom. Both the top UHF antenna and the bottom UHF antenna in the dual-frequency antenna box simultaneously read the UHF tags on the books. The reading results are cross-verified, reducing misreading caused by UHF antenna overflow. Simultaneously, the high-frequency antenna in the dual-frequency antenna box reads the high-frequency RFID tags on the books, thus solving the technical problem in existing traditional book return machines that cannot simultaneously identify books with both high-frequency and UHF tags.
