基于单片机的自动售货机的设计.docxVIP

摘 要 自动售货机是近些年来兴起的一种通过FPGA或者单片机等硬件支持的智能设备。它广泛的应用于商场，公寓，火车汽车站等人流较密集且购物需求大的地方。自动售货机通过硬件支持，通过以编写好的程序自动出货自动找零，但货物一旦售罄就需人为去补充。人们生活水平不断提高，对自动售货机的需求量就越大，所以对它的研究和完善具有重要的商业价值。传统的售货机只能用现金支付，随着近些年的发展移动终端支付方式越来越受欢迎。一些售货机也开始拓展移动支付的功能，极大地满足了人们的需要，给他们提供了许许多多的便利。同时，移动支付功能也克服了现金支付找零会存在的一些问题。本课题主要是研究一款基于89C51单片机的自动售货机，并实现自由选货、出货、收钱、找零等功能。本文介绍了单片机的选型、总的设计框架、软件仿真、硬件电路的实现等各个模块。 关键词：自动售货机； 单片机； 编译仿真 Abstract Vending machines are the kind of intelligent devices that have been supported by hardware such as FPGAs or microcontrollers in recent years. It is widely used in shopping malls, apartments, bus stations and other crowded and shopping needs of large places. Automatic vending machine through hardware support, through the preparation of a good program automatically sent to automatically change the zero, but the goods once sold out to be added to the people. Peoples living standards continue to improve, the demand for vending machines is greater, so its research and improvement has important commercial value. Traditional vending machines can only be paid in cash, with the development of mobile terminals in recent years, more and more popular way to pay. Some vending machines have begun to expand the function of mobile payment, greatly to meet the needs of people, to provide them with a lot of convenience. At the same time, the mobile payment function also overcomes some of the problems that cash payments will have. This topic is mainly to study a 89C51 single-chip vending machines, and to achieve free selection of goods, shipping, money, change and other functions. This article describes the single-chip selection, the overall design framework, software simulation, hardware circuit implementation and other modules.
