【摘要】：自动售餐机是一种专门用来售卖盒饭快餐的自动售货机。随着城市规模的快速发展和网上订餐业务的推广,越来越多的人参与到线上点餐线下配送这种O2O模式的外卖业务中来,但这并不能满足人们的需求,随着点餐量增多问题也越来越多,如食物送达不及时、饭菜不新鲜、价格无优势等等。随着自动化技术的进步,自动售货机所售卖的产品范围也越来越广,因此出现了自动售卖盒饭的售餐机,但现有的售餐机因为餐品单一、操作繁琐、价格无优势等问题并没有得到大规模的推广,因此设计一款能够改善上述问题的自动售餐机成为一种需要。通过调查研究多种类型的自动售货机以及现有的自动售餐机,分析用户操作习惯,结合企业要求,确定机器的机械结构及组成,在此基础上,确定该控制系统的总体方案,以工控机作为上位机,触摸显示器为人机交互界面,PLC为主控制器,工业无线路由器为物联网设备,伺服电机和直流电机为执行机构,通过移动支付方式,对不同种类的盒饭进行组合售卖。上位机程序采用C#语言基于Windows系统的.NET平台编写,并建立相应的数据库。根据控制系统方案的要求,对自动售餐机的硬件与软件进行设计。硬件设计包括对PLC、上位机、触摸显示器、伺服系统等硬件的选型以及根据选型结果设计电气系统,电气系统的设计包括主回路设计、PLC控制回路设计和伺服系统电路设计。软件设计包括PLC程序设计、上位机程序设计、数据库设计、采用Modbus通信协议实现上位机下位机的数据交换和人机交互界面的设计。自动售餐机能够实现正常的购买功能,用户购买指定餐品在短时间内完成取货、加热、出货等一系列动作,在此基础上要继续进行优化,使得用户体验更好、功能更加丰富。
[Abstract]:Automatic food vending machine is a kind of vending machine specially used to sell fast food box. With the rapid development of city scale and the promotion of online ordering business. More and more people are involved in the O2O delivery business, but this does not meet the needs of the people, with the increase in the number of meals, such as food delivery is not timely. With the advance of automation technology, the range of products sold by vending machines has become more and more extensive, so there has been an automatic selling of lunch boxes. However, the existing food vending machine has not been promoted on a large scale because of the single meal products, cumbersome operation, no price advantages and so on. Therefore, it is necessary to design an automatic meal vending machine which can improve the above problems. Through investigation and research on various types of vending machines and existing automatic meal vending machines, we can analyze the operating habits of users and combine with the requirements of enterprises. The mechanical structure and composition of the machine are determined. On this basis, the overall scheme of the control system is determined. The industrial control computer is used as the host computer and the touch display as the man-machine interactive interface PLC as the main controller. Industrial wireless routers for the Internet of things equipment, servo motor and DC motor as the actuator, through mobile payment. The upper computer program is written on. Net platform based on Windows system in C # language, and the corresponding database is established. According to the requirements of the control system scheme. The hardware design includes the selection of PLC, upper computer, touch display, servo system and electrical system according to the result of selection. The design of electrical system includes the design of main circuit and the circuit of servo system. The software design includes PLC program design, host computer program design and database design. The Modbus communication protocol is used to realize the data exchange and the design of the man-machine interface of the upper computer and the lower computer, and the automatic meal selling machine can realize the normal purchasing function. A series of actions, such as picking up, heating, shipping and so on, will be completed in a short period of time. On this basis, we should continue to optimize to make the user experience better and function richer.
