自动售货机控制系统的设计与仿真

摘要

随着社会的进步，科学的发展，生活水平的提高，单一传统的生活方式已经不能满足现代居民对高品质生活的追求，在这种现象下，许多自动化设备应时代应潮流而生。自动售货机作为自动化设备中的最常见的设备之一，由于其众多的优点，已经在世界各地得到了普遍的发展并且还在不断地发展。自动售货机掀起了继百货商店和超市之后的又一零售狂潮，这种智能售货系统在车站、教学楼、办公楼等公共场所有着广阔的发展前景。

本文在对自动售货机的背景历史和发展趋势进行了研究介绍之后，对课题中的自动售货机系统进行了整体的设计及规划。该自动售货机控制系统是基于EDA技术来实现的，同时，利用Altera公司的QuartusⅡ14.0作为其软件开发平台，利用VHDL编程语言输入的方式完成了软件设计。本设计方案对整个控制系统进行了层次化的编写。把整个系统划分为6个子模块，分别是找零计算模块、确认取消控制模块、找零控制模块、总钱数加和模块、显示模块、锁定模块，并且对每一个子模块进行了详细的软件设计。在顶层文件中通过调用各个子模块来完成vhdl程序的设计。

最后在对每一个子模块完成了功能仿真测试验证，同时也对整个系统进行顶层设计和仿真测试，测试结果表明了整个控制系统的合理性以及正确性。整个控制系统设计简单合理，操作简单，满足售货机的基本要求，具有一定的实用意义。

Abstract

Abstract: With the progress of the society, the development of the scientific, and the improvement of living standards, single traditional way of life has not meet modern residents' pursuit of high quality life, under this kind of phenomenon, a number of automation equipment should come into being. Vending machine as one of the most common equipment in the automation equipment, has been develop all over the world and develop constantly because it has many advantages .Vending machines set off after department stores and supermarkets in another retail frenzy, this intelligent vending system has broad prospects for development in the station, school buildings, office buildings and other public places.

Based on the background of the vending machine, the article designs and plans the project of vending machine system after introducing the history and development trend.The vending machine control system is based on the EDA technology to realize, at the same time, it used Quarter Ⅱ 14.0 of the Altera corporation as the software development platform, taking advantage of VHDL programming language input completed the software design. The design scheme is hierarchical write for the whole hierarchical control system.The whole system is divided into six sub modules, change calculation module, confirming cancellation control module, the change control module, total amount module, display module, locking module, and each child module software design is design in detail.On the top floor file by calling each module to complete the VHDL program design.

Finally, The design scheme completed the function simulation test to verify for each child modules, and conducts Top-level design and simulation test for the whole system, the test results show the rationality and validity of the whole control system. The design of the whole control system is simple and reasonable, the operation is simple, it meets the basic requirement of the vending machine and has certain practical significance.
