摘要
综合国力的提高使人民不断富裕起来，他们的业余生活逐渐丰富，我国的文化事业也开始全面发展，图书馆地位越来越高，人们去图书馆的次数越来越多，然而图书馆的管理模式并没有实现大幅度的改善对图书的管理也不可避免的出现了许多问题。目前，“条形码+集成管理系统+磁条防盗”技术依旧是为国内图书馆所采用的主流技术，但这种方式存在条码易污染、易破坏且安全性差的问题。因此，图书管理系统的升级换代，简化还书系统是非常有必要的，对我国的全面发展具有重要的意义。
书籍是人类历史的见证者也是中华文明的传承者，有效管理图书是至关重要的，对图书进行保护、高效的整理和分配是图书馆的主要任务。本文主要介绍了通过PLC芯片对图书馆的还书系统进行智能控制，它克服了传统使用条形码，具有的易污染、易破坏且安全性差的弊端，采用UHF图书标签，提高了图书管理的效率和安全性。
论文首先介绍了本次毕业设计的课题背景，分析了国内外智能还书的发展现状及设计智能还书机的意义。在此基础上，提出了基于博途软件为核心，RFID 技术为辅助的智能还书机的总体设计。

Abstract
Theimprovementoftheoverallnationalstrength has made the peoplemoreprosperous, their spare-time life is gradually enriched, China's cultural undertakings have also begun to develop in an all-round way. The status of libraries is getting higher and higher. People go to libraries more and more. However, the management mode of libraries has not been greatly improved and many problems inevitably arise. At present,"barcode + integrated management system + magnetic bar anti-theft" technology is still the mainstream technology used by domestic libraries,but this way has the problems of easy pollution,easy destruction and poor security. Therefore, it is very necessary to upgrade the library management system and simplify the book return system,which is of great significance to the overall development of our country.
Books are the witnesses of human history and the inheritors of Chinese civilization. Effective management of books is of paramount importance. The main task of libraries is to protect, organize and distribute books efficiently.This paper mainly introduces the intelligent control of library's book return system through PLC chip. It overcomes the disadvantages of traditional use of bar code, which is easy to pollute, easy to destroy and poor security. UHF book label is used to improve books’efficiency and security of management.
Firstly, the thesis introduces the background of this graduation project, analyses the development status of intelligent book returning at home and abroad and the significance of designing intelligent book returning machine. On this basis, the general design of intelligent Book returner based on Botu software as the core and RFID technology and the assistant is put forward.
Key words: PLC RFID UHF book label returner
