饮料自动售卖机设计
摘要
本系统是基于单片微型计算机控制的散装饮料自动售货系统，用单片机的基本语言c语言和汇编语言来进行软件设计。本机是如此方便以至于可以安置在公园、车站、机场或者商场门口。该系统可分为纸杯销售机构部分、饮料销售机构部分。微机控制部分的功能又分四个部分。首先，商业行为应该讲求公正却不能没有防人之心，所以我们设置了硬币检测装置；其次，检测出结果后要进行退币或者收取动作，我们设计了退收币控制部分；再次，收了钱财当然要尽快让消费者拿到取饮料的纸杯，纸杯销售控制方案也必不可少；最后就要控制饮料的抽取和流出了。硬币检测装置在本设计中虽涉及不多，但它却要做诸如检验硬币真假并发出控制信号的很多事情；退收币机构在识别信号和按钮信号的控制下进行退收币动作；纸杯销售机构和饮料销售机构则根据识别结果并配合按钮控制信号完成销售任务。本设计中涉及到AT89S51和8031两种单片机的应用，如此安排以示两者区别，其实可以将个控制部分集成在一两个单片机上即足够了。本文详细阐述了此系统的机构设计方案和控制方案及设计过程中可能出现的问题及解决方案。设计者的工作包括：系统各功能单元方案的设计；各功能单元控制方案设计；画出各功能单元原理图；根据原理图设计c语言或汇编语言源程序；部分机构的绘图及加工工艺等。

Abstract
This system is an automaticvending machine for unpacked drinkings on basis of the contrlling of single-chip microcomputer,whose controlling program iswritted by the basic language for microconroller such as the c language and the assembler language. This device is so convenient that it can be setted in park,station,airport or outside the door of some supermarket. This system is composed of thevending mechanism for paper cups and drinkings. The controlling part can be seperated into four. Firstly,commercial activities can’t miss some bad boyswhile it should pursue justness,so coin-detaction device is setted up.secondly,the action of giving back or taking in the coins according to the result of detection is suggested,sowe build up the controlling portion for coins’ gooing or coming.again,the cup-distribution section is neccsery before consumerwill be thirsty for their cups for beverage.lastly,we should take measures to cnotrol the extracting and outflowing of the beverage.although little is referred to the content of coin-detection,it’s imprtant because itwill do so many contributions such asverifying coins and sending out some controlling signal.the machine for coinswill rotate in in the light of signals from coin-detection and press-button. Thevending mechanisms for cups and beveragewill accomplish the distribution mission based on the outcome of coins’ identifying in coordinationwith button’signal. As to show the difference,Two kinds of single-chip microcontroller as AT89S51 and 8031 are involed in this project. But as a matter of fact one or two is enough.this paper detailed the scheme of the system’s mechanisms and their controlling even some possible problems and their sollution. Theworks of designer are: the disgn ofvarious units of the system; the disgn of the contrlling schemes; drawing system schematics;writing assembly language code or the c language code according the schematics; the drawing of some mechanisms and the machining technological disgn.
