Description

Technical Field

[0001] This invention relates to the field of Internet technology, specifically to a campus second-hand book recycling and sales system. Background Technology

[0002] With the popularization of higher education, the circulation of textbooks, teaching aids and various reading materials on campus has increased year by year, and the problem of handling second-hand books has gradually become prominent. At present, the recycling and sale of second-hand books on campus mainly rely on the following methods: (1) Offline flea markets: mostly held temporarily at the end of the semester, which are subject to obvious time and venue restrictions, student participation is scattered, book transaction efficiency is low, and there is a lack of standardized pricing standards, which can easily lead to disputes; (2) Circulation within classes or clubs: the scope is limited to small groups, making it difficult to achieve cross-major and cross-grade resource sharing, and a large number of valuable books are left idle or discarded due to information blockage.

[0003] Current library recycling mechanisms: While some university libraries conduct secondhand book recycling, the process is cumbersome, requiring manual registration, sorting, and shelving, resulting in high labor costs. Furthermore, most recycled books circulate as donations, lacking market-based incentives, limiting student participation. Online trading platforms: Such as campus BBS and secondhand trading apps, while breaking down time and space limitations, suffer from high logistics costs, long transaction cycles, and difficulty in verifying book condition. Moreover, the lack of a unified regulatory system on campus makes them susceptible to false information and fraud.

[0004] Furthermore, the traditional model relies on manual judgment for the classification and pricing of secondhand books, which is highly subjective and difficult to accurately match market demand. This leads to a widespread phenomenon of popular books being in short supply while less popular books are piling up unsold. At the same time, the book recycling and sales processes are disconnected, lacking closed-loop management. A large number of recyclable books are treated as waste paper, resulting in resource waste and contradicting the concept of building a green campus. Therefore, there is an urgent need for an integrated and intelligent device to achieve efficient recycling, accurate classification, convenient sales, and full-process management of secondhand books on campus. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the technical solution provided by the present invention is: a campus second-hand book recycling and sales system, comprising:

[0008] A sorting area is located between the recycling area and the sales area, and the sorting area is equipped with a workbench, scanning equipment and label printer;

[0009] The student operation module includes a touch screen located in the center of the front of the device. The student operation module includes a used book recycling unit and a used book purchasing unit. The used book recycling unit includes a free recycling unit option and a low-price recycling unit. The used book purchasing unit supports searching for books by title, author, and category.

[0010] The staff operation module supports password or fingerprint login and includes a book classification unit, a book pricing unit, a book shelving unit, a book de-shelving unit, an inventory management unit, and a data statistics unit.

[0011] The payment system is integrated with the campus card system, WeChat Pay platform, and Alipay payment platform, and adopts encrypted transmission and security authentication technology.

[0012] Preferably, the adjustable partition of the recycling bin can adjust the spatial layout according to the size and quantity of the books.

[0013] Preferably, there are multiple sales compartments, the book retrieval slot is located on the side of the sales area, and each sales compartment is equipped with a book pusher device that can automatically unlock and push the book to the retrieval slot after successful payment.

[0014] Preferably, the scanning device is capable of scanning the ISBN number or barcode of a book to obtain basic book information, and the label printer is capable of printing labels containing the book price, number, and QR code.

[0015] Preferably, the free recycling unit option can automatically record information and issue points after students input personal and book information and put in the books. The points can be used to offset the cost of books or redeem gifts.

[0016] Preferably, after students input their personal information and book information, the low-price recycling unit can automatically assess the price based on the condition of the books and market demand, and deposit the recycling amount into the student's account after confirmation.

[0017] Preferably, the data statistics unit is capable of generating reports on book recycling volume, sales volume, sales revenue, and popular books.

[0019] (1) Book recycling: Students select the recycling method through the student operation module, enter personal information and book information, put the books into the recycling slot, and the device automatically confirms the recycling and records the information. When recycling at a low price, the device automatically evaluates the price and deposits the amount into the student's account.

[0020] (2) Classified book pricing: Staff members retrieve the recycled books through the staff operation module and classify and price the books in the classification area according to their condition, content quality, and market demand; increase the price unit for scarce or popular books, and decrease the price unit for old or unpopular books or set them to free.

[0021] (3) Books are put on the shelves for sale: Staff put the books after the categorized book pricing unit into the sales grid and enter the book information and price into the system;

[0022] (4) Book selection: Students can search for books through the student operation module, view the details and choose to receive them for free or purchase them at a low price. After successful payment, the device will automatically open the corresponding compartment lock and the student can take the book out from the book retrieval port.

[0023] (5) Inventory management: Staff monitor the inventory in the sales area through the back-end system, replenish the inventory in a timely manner after the books are sold, and carry out promotional activities for books that have not been sold for a long time.

[0024] The advantages of this invention compared to the prior art are:

[0025] (1) The device of this invention achieves integrated operation of "recycling-classification-pricing-sales" through the modular design of recycling area, sorting area and sales area, avoiding the problem of disconnection between links in the traditional model. The combination of barcode scanning device and label printer ensures accurate flow of book information; the student operation module realizes self-service recycling and purchase through touch screen, reducing manual intervention and improving efficiency.

[0026] (2) This invention supports both “free recycling (points reward)” and “low-price recycling (cash return)” modes. Points can be used to offset the cost of books or redeem gifts, while cash is directly deposited into the campus card account, meeting the needs of different students.

[0027] (3) The present invention generates popular book reports and unsold book lists through the data statistics unit, and staff can dynamically adjust pricing strategies to achieve "supply based on demand".

[0028] In conclusion, this device, through its intelligent and modular design, effectively solves the pain points in the circulation of second-hand books on campus. It demonstrates significant advantages in improving resource utilization, reducing management costs, and stimulating student participation, and has broad promotional value.
