Design And Implementation Of Smart Library System Based On Radio Frequency Identification

At present,most libraries use the "barcode + security magnetic stripe" method to manage the books in the collection.This management method can realize the automatic identification of book information,which improves the work efficiency of the library to a certain extent,but the barcode The technology is based on the principle of optics,and only one book can be scanned at a time,which is inefficient in the scenario of multiple books being borrowed and returned,and the barcode is easily damaged,the recognition distance is close,and the moving object cannot be recognized.RFID(Radio Frequency Identification)technology has the characteristics of anti-pollution,wear resistance,long recognition distance,and multiple targets can be identified at one time.Its application in smart library business is feasible.In order to build a smarter library system,improve the work efficiency of library staff,and improve the service quality of readers,RFID technology is used instead of bar code technology to manage books.The fixed RFID card reader can read multiple RFID tags at a time,and readers can borrow multiple books in one scan,and can collect the book data of the reading room being moved,and then send it to the back end for storage and calculation,and get the library A statistical report on the popularity of books for reference by staff when purchasing books.In addition,collaborative filtering technology is also used to analyze and obtain the user's reading preferences,and push books that may be of interest to the user on the system homepage.Judging from the results of the functional tests,the operation of each system function is in line with expectations and can meet the needs of library users.From the results of performance testing,under normal system traffic,the response time of the system will not give the user a noticeable delay,nor will it cause an excessive burden on the server CPU,so it meets the performance requirements.
