Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Such as figure 1 , 2 shown

[0025] A book positioning and navigation system based on visible light communication, which mainly consists of an LED module on the ceiling of a library, a visible light communication module 2 installed on the spine of a book 1 , a user terminal 5 and a background server 6 . The visible light communication module 2 stores the book ID, and the book ID is stored in the background server for reference. The visible light communication module 2 is installed on the upper part of the spine of the book 1, and this position is least likely to be blocked, so as to ensure the accuracy of positioning. The user terminal 5 includes a user request module, a location information acquisition module, an information processing module, an interaction module and a display module. The user enters the book ID through the request module ...

Abstract

The invention provides a book positioning system based on visible light communication, mainly consisting of an LED lighting array on a library ceiling; an LED information transmitting module; a visible light communication module at the upper part of a book spine; a user terminal; and a background server. A book communication module stores a book ID, the user terminal searches the book ID and obtains the location of a book through the LED array, and a user can find the book through the location information. In the book positioning system provided by the invention, an LED lamp is used for lighting and sending the location information at the same time, so that the economic cost is relatively low; and at the same time, book management self-help can be realized, the manpower and material resource cost of book classification is shortened, the time for the user to find the book can be shortened, and the library management and resource use efficiency can be improved.

Description

technical field [0001] The present invention relates to the technical field of visible light communication, in particular to a book search technology, in particular to a book positioning and navigation system based on visible light communication. Background technique [0002] In the existing library, books are borrowed, returned and classified manually. The librarian arranges the books on the bookshelf in order according to the call number to classify the books. Readers search for the corresponding bookshelf according to the call number, and then find the the corresponding book. This method consumes manpower and material resources and is inefficient. In addition, the library has a large area and complex functional divisions, and the library is a public place. After reading the books, readers may not necessarily return them to their original places, resulting in disordered arrangement of the books, and the system shows that the books have not been checked out but cannot be f...
