基于单片机的自动还书箱控制系统的设计.doc

摘 要 在现今高校图书馆，城市图书馆中，图书的借阅量逐年提升，对图书进行分类和对图书的信息汇总变得更加繁琐。还书箱能够方便读者24小时还书，但是普通的还书箱由于构造简单，功能单一，只能够完成储藏图书这一功能，通过它还书既不能迅速的清除借阅记录，又由于图书再放入书箱时会相互叠加，碰撞，对图书的破坏较严重，而且还会加大工作人员的工作量。所以一个能够完成对图书进行储藏，保护，清除借阅记录的还书箱是现代图书馆所必备的设施之一。 本次设计主要完成了单片机对分类电动机和控制书架高度的电动机的顺序控制，设计主要分为硬件设计和软件设计两部分。其硬件设计中利用了单片机8031、8255A芯片、电动机、读码器、传感器等组成了硬件控制电路。在软件设计中，首先设计好程序流程图，编写程序，然后结合硬件进行调试。该系统实现对2类不同的图书进行分类、清除借阅记录达到预期的设计要求。 关键词：单片机；借阅记录；分类；自动控制 Abstract In the current university library, the city library, books circulation increase year by year, classifying books and books information summary becomes more complicated. Book drop can make it easier for readers to return the book for 24 hours, but the ordinary book drop because of its simple structure, single function, can only be completed books that a function of storage, can neither quickly through it also book borrowed record, and because of the book. In the case when the superimposition, collision, and serious damage to the books, but also will increase the workload of staff. So a able to finish the book storage, protection, remove borrowed record book drop is one of the essential qualities of modern library facilities. This design mainly completed the single chip microcomputer for classification of motor and control the shelf height of sequence control, design is mainly divided into two parts, hardware design and software design. Using the single chip microcomputer 8031, 8255 in the design of its hardware, motor, reading a chip decoder hardware control circuit, sensor, etc. Good program flow chart in software design, the first design, program, and then combined with the hardware debugging. The system implemented the two different types of book classification, clear borrowed record the desired design requirements Keywords：Single chip microcomputer; Borrowed record; Classification; The automatic control 1 绪 论 1 1.1 课题背景 1 1.2 自动还书箱设计的目的和意义 1 2 单片机控制系统介绍 2 2.1 自动还书箱的总体设计方案 2 3 硬件系统的设计 4 3.1 硬件总体设计 4 3.2 单片机控制系统的硬件构成 4 3.3 主控芯片80C31 4 3.4 并行 I/O 接口电路 7
