文档介绍：摘要
作为公共文化服务体系之一的图书馆，近年来发展迅速。各图书馆的服务方式层出不穷，通过探索动态创新的服务模式，来拓展图书馆内伸外延的服务空间，不断提高服务质量，使图书馆的资源走出图书馆，走向城乡、走向读者，与读者之间零距离地亲密接触。
基于此，我院开始研究图书馆自助还书机。图书馆自助还书机可以减少读者还书的等待时间和减少对管理员的依赖，享受自己动手完成还书操作过程，还能保障读者阅读隐私，让读者充分享受到图书馆服务的现代化形式。
图书馆自助还书机中最重要的部分是整个控制系统的设计，根据现代控制理论的发展，本控制系统采用的控制核心是可编程控制器（PLC）。随着可编程控制器（PLC）技术的发展，把PLC控制技术应用于图书馆自助还书机控制系统中，替代了先前的继电器、接触器控制，取得了很好的使用效果。

Abstract
Library has developed quickly in those years as one public cultural service system. There are so many service styles in libraries. In order to expand service epitaxial spaces and improve the quality of service, people began to explore the dynamic innovative service modes, which can make the library information go out and have an zero-distance contact with readers.
So, our school began to make self-help book return machine. It is a machine that can reduce waiting time of readers and reliance on library manager. Readers can return books by themselves, at the same time, they can protect their privacy. What’s more ,they can get good feelings from modern service style.
The most important part of self-help book return machine is the design of the whole control system. According to the development of modern control theory, the core of this control system is PLC. with the development of PLC, instead of previous relays, contactor control, the use of PLC in library self-help book return got a fine result.
