Description

Book fast shelf and book search device

technical field

The invention relates to the field of electronics, in particular to a device for quickly putting books on shelves and searching for books. the

Background technique

A library is a public service organization that collects, organizes, and stores books and materials for people to read. Libraries have the functions of preserving human cultural heritage, developing information resources, and participating in social education. There are a large number of books in the library collection, so the management of books and the search for target books when borrowing are quite tedious tasks.

At present, domestic librarians use the call number to determine the specific placement of books when they put books on the shelves and when users are looking for books. It is very inefficient when books are put on shelves and found.

In order to change this status quo, some schemes have tried to solve this kind of problem, such as Chinese patent CN103021102A, which uses a book locator to scan the storage area of books that have not been lent out, and when the book to be searched is scanned, it will call the police to realize the positioning of the book , although the positioning is accurate, the scanning area is large and the barcodes of all books need to be changed to the side of the book, and the changes are large; another example is the Chinese patent CN101004794A, which uses a walking device to scan the barcode on the bookshelf and transmits a signal to the computer, and the computer then The position of the book is determined according to the barcode on the bookshelf and the barcode of the book. Although accurate positioning is also mentioned, the barcode signal of the shelf and the book is also not eye-catching enough, and the problem of returning the book to the shelf has not been changed. the
