Design And Implementation Of Digital Library System Considering Book Dislocation Query Function

With the development of the information age,the development model of the library has gradually transitioned from a traditional library to a digital library.The digital library is the extension and development of traditional libraries in the information age.Digital libraries are distributed large-scale information centers.There is no time and space restrictions.It is convenient to use and has become a trend of library construction and development.However,under the wave of this digital library,the development of the intelligent management of book space information is relatively lagging.The problem of book misalignment and placement has always been one of the core issues of book management.The so-called book dislocation is that the theoretical position of the book does not match the real position.Once the book is dislocated,the borrower cannot find the required books through the book retrieval system.At the same time,it is difficult for the book administrator to find the dislocation to place the book,causing problems such as chaos and library resources.This article is based on the actual situation of the traditional library book misalignment.The 3DS MAX and the three-dimensional GIS platform are used to build a three-dimensional digital library framework with 3DS MAX and the three-dimensional GIS platform.Solve the problem of visualization of the three-dimensional space of the book and the problem of book dislocation.Specifically: The main tasks of this article are as follows:1.In order to realize the interactive function of the three-dimensional scenes of the library and the book error program,first of all,build the basic model of the library through3 DS MAX,including basic bookshelves,floors,and walls.For the model coordinate system and model topology inspection work,the model has the basis for the three-dimensional GIS space query;second,the three-dimensional model has space attribute information through the spatial position of the SQL Server database storage storage book holder and books;and finally,it will have space attributes The three-dimensional visualization model of information is integrated and developed on Visual Studio,and connected to the SQL Server database to achieve the visualization and model attribute work of the library.Mutual check function and book search visualization function.2.In order to achieve the script dislocation query function,first of all,the construction of the underlying logical language of the library through the Visual Basic;second,integrate development with SQL Server,build a unit pattern table,and build book attribute field information.Finally,the book attributes will be Information enters into the space substantive bookshelf cell.When the book misalignment query,first,scan the bookshelf barcode through the manual handheld scanning device,determine the real-time location of the bookshelf cell information and the scanning equipment;second,the ISBN(INTERNATIONAL BOOK NUMBER)code on the bookshelf’s spinal side is performed.Scanning,scanning device emits active light sources to illuminate the product barcode,and then converts the optical signal into a electrical signal through an optoelectronics converter.The electrical signal is transformed into a digital signal after the signal processing of amplification,filtering,and other signals.For processing,you can get the book ISBN code.Finally,the obtained book ISBN code information matches the position with the system database.If the matching fails,it will show the theoretical cell theoretical cell space position.After verification,this system has high recognition accuracy,fast recognition speed,and clear model visualization interface.This system can improve the efficiency of management of managers’ books,optimize the user experience of borrowers,and put forward a reliable solution for the development of the digital library,which has important practical value.
