1. Project background
A large number of literature and information resources are actively developed and widely used as one of the important functions of the library, and it is also the basis for the library to undertake various functions. Due to the large number and rapid growth of the production of social documents, the types and forms of social documents are complex, the document’s timeliness is strong, the spread of documents is accelerated, the content of documents is overlapped, and the languages used in documents are expanded. It is not easy to use.
Libraries need to process and analyze document information to form an orderly, regular, and continuous flow of information to adapt to more extensive communication and transmission, so that readers can make better use of them.
At present, the technical means of “secure magnetic stripe + barcode” is widely used in the domestic library management system. The security magnetic stripe is used as the security guarantee of the books, and the barcode is used as the ID card of the books, which solves some problems in the book management, but there are still some problems. some problems:
※ It is difficult to arrange and arrange the shelves, and the labor intensity is high;
※ Book search and inventory inventory are tedious and time-consuming;
※ Audio-visual books are difficult to circulate;
※ The degree of automation is low, and the management lacks humanization;
※ The magnetic stripe is easy to be demagnetized, and the anti-theft effect is poor, etc.;
※ Library managers realize that under the new situation, the degree of informatization of library management needs to be greatly improved. Modern libraries need to achieve automatic book inventory, book self-service borrowing and return, book regional positioning, and automatic book sorting to meet current development requirements. Is there a solution that concentrates the advantages of “barcode” and meets the needs of library management under the new situation? The answer is yes-RFID library intelligent management system is not only safe, reliable, and efficient, but also It can meet the development requirements of library management for a long period of time in the future.
2. System implementation process
1.1 System network diagram
1.2 Operation process
New book entry:
First, attach RFID electronic tags to the books. Use the label conversion device to write the data information into the electronic label. This process is to equip each book with a unique ID card.
On the shelf, along the shelf:
For new books with electronic tags, use the cart-type mobile inventory system to scan the books. The system will automatically locate the bookshelf where the book should be stored on the map, and push the books on the car to the designated bookshelf. Using the cart-type mobile inventory system, the bookshelves can be scanned one by one, and the system will automatically pick out the wrong books and mark the correct position.
inventory:
When inventorying library books, you can use a mobile inventory system or a handheld inventory system to scan all the bookshelves that need to be inventoryed. The data can be entered into the database through wireless network transmission and the inventory can be completed, which can save a lot of manpower and material resources.
Self-service book borrowing and returning:
When borrowing books, readers only need to scan the library card on the self-checkout machine, and then put the borrowed books in the scanning area of the checkout machine together, and confirm the borrowed books by scanning. The system can then enter the borrowing information to complete the borrowing. And use a thermal printer to print receipts. Full reader self-help, convenient and fast. The operation of returning the book is simpler. You only need to scan the book to complete the return operation and print the return receipt.
24-hour self-service book return system:
The self-service book return system can be installed through the wall like a bank ATM or placed in a suitable location, which is convenient for readers to return books at any time. Readers only need to put the book in the book return slot, and after confirmation, the book can be returned and the book return voucher can be printed.
Security access control:
When the books that have not gone through the procedures for borrowing books pass through the security gate, the system will automatically give an audible and visual alarm to prevent the books from being taken out. Safe access control supports two working modes, online and offline, making the system safer and more reliable.
Mobile library:
After the reader scans the library card and confirms his identity, he selects the book he wants to borrow. The system will automatically send the book to the book outlet and print the receipt. In the process of returning the book, you only need to put the book in the book return port, and the system automatically recognizes and prints out the book return receipt, and automatically puts the book in the correct position.
Three, program advantages
3.1 Simplify the process of borrowing and returning books
Although the existing book borrowing and returning process introduces a barcode scanning system, it still needs to manually open the book’s title page and find the position of the barcode before scanning the barcode. Such an operation process is relatively cumbersome, and the efficiency of borrowing and returning books is low. At the same time, the barcode is easy to break, and it often happens that the barcode cannot be read and the barcode needs to be replaced. This will not only affect the efficiency of borrowing and returning books, but also affect the reader’s satisfaction with the library.
It can be used in conjunction with the automatic borrowing and returning system. When borrowing books, readers only need to scan the borrowing card on the self-checking machine, and then put the borrowed books in the scanning area of the borrowing and returning machine, and confirm the borrowed books by scanning. The system can then enter the borrowing information to complete the borrowing. And use a thermal printer to print receipts. Full reader self-help, convenient and fast.The operation of returning the book is simpler. You only need to scan the book to complete the return operation and print the return receipt.
Therefore, it is urgent to introduce advanced reading and writing technology to realize the intelligent book borrowing and returning process, improving the security of information storage, the reliability of information reading and writing, and the speed and speed of borrowing and returning books.
3.2 Reduce the workload of inventory and search
Relying on manual book inventory work, the workload is large and the efficiency is low. Administrators have to classify, place and record books based on their own memory, which is time-consuming and difficult to achieve. It is necessary to introduce advanced technology to realize the intelligentization of book inventory.
3.3 Improve the security of the anti-theft system
The accuracy of the existing library magnetic stripe anti-theft system is low, and the magnetic stripe is easily weakened, so the probability of false alarms and false alarms is high. Therefore, it is necessary to improve the existing book anti-theft system and adopt more reliable anti-theft technology.
3.4 Change the disconnection between lending management and security and anti-theft
The library anti-theft system is still an isolated system. Books must be magnetized before being returned and put on shelves, and demagnetized when they are loaned out. The workload is heavy, which directly affects the efficiency of book circulation and management. It is impossible to record the information of the stolen books while discovering the theft, which has a great impact on the daily inventory and replenishment of books.
Therefore, it is necessary to improve the existing management system, link the anti-theft system with the book circulation management system, and record the historical record of each book in and out of the library, so that it can be matched with the historical record of borrowing and returning books.
3.5 Improve the satisfaction of library staff
Due to the repetitive work of the library staff over the years and the heavy work of the library itself, it is easy for the library staff to have certain negative thoughts about the work of the library; due to the flaws in the management, the library management Readers are also very troubled, and readers are also dissatisfied with the library, resulting in a decline in library staff satisfaction with library work. Through the technical transformation of the library management system, technical means can be used to make up for the shortcomings in management, and at the same time liberate the staff from the heavy daily work of the library.
3.6 Improve readers’ satisfaction with borrowing and returning books
Readers often feel dissatisfied with the library. The main reasons are as follows:
1) The efficiency of borrowing and returning books is low, the waiting time in line is too long, and the unnecessary waste of time leads to dissatisfaction of readers;
2) The bar code of the borrowed and returned book cannot be read, which increases the waiting time of the reader and causes the reader to be dissatisfied;
3) Since the library does not have an effective means to inventory books, readers found a certain book in the collection through the query system, but it took a long time to find it. The reason may be that the book was stolen, but because of management The system does not have accurate records, and as a result, readers are dissatisfied with the library;
Through the above analysis, it can be concluded that many problems in current library management and many inconveniences for readers in borrowing and returning books are caused by the defects of the barcode technology currently used. If RFID is adopted, many functions that cannot be realized by barcode technology can be realized, thereby improving the function and system reliability of the library’s management system.
