基于PLC的自动售货机控制系统的设计(任务书,开题报告,外文翻译,论文说明书12000字)
摘要
通过对自动售货机功能的调查,发现自动售货机虽然已经具备部分功能的全自动,但是还具有部分需要改善的地方以满足更广大的需求。本设计主要采用西门子1200系列PLC对自动售货机控制系统进行设计,利用博图软件建立项目,编制自动售货机的控制程序,编制自动售货机的组态界面,模拟仿真使用自动售货机购物的全过程,连接实物模拟仿真使用自动售货机购物的全过程。本次设计主要是自动售货机整体的PLC编程设计,自动售货机除了拥有传统的投币购物找零的功能外还增加了模拟二维码支付购物的功能。采用电机驱动旋转机构可以简单的实现货物的输送;采用电机配合拖物板来实现自动售货机送出货物的功能。这个设计符合现代节能环保的理念,符合上班族的日常需求,也能迎合现在的移动支付潮流,使售货机的设计更加智能,使售货机的出货方式更加简单,使售货机的支付方式更加多样化。

Abstract
Through the investigation of the functions of modern vending machines, it is found that although modern vending machines have some fully automatic functions, they still have some areas to be improved to meet the needs of a larger number of people. This design mainly adopts PLC1200 to the vending machine control system design, using Portal software build project, control program of the vending machine for compiling the vending machine configuration interface, the whole process of the simulation using the vending machine shopping and connection half physical simulation during the process of using the vending machine shopping. This design is mainly the whole vending machine PLC programming design, vending machine in addition to the traditional coin shopping change function is also added to simulate the two-dimensional code payment function of shopping and shopping end free use of microwave function. The use of motor driven rotating mechanism can be simple to achieve the delivery of goods; The motor and the pallet are used to realize the function of sending goods from the vending machine. This design is in line with the concept of modern energy saving and environmental protection, in line with the daily needs of office workers, but also to meet the current mobile payment trend, make the vending machine design more reasonable, make the vending machine shipment more rapid, more diversified payment.

Key words: PLC;Vending machine;Analog two-dimensional code payment
