Design And Implementation Of Self-service Dining System

With the popularity of Internet applications,many changes have taken place in people's lifestyles,and many traditional service industries have become more and more intelligent,and the way of catering services needs to be modernized to meet people's living standards and consumption habit.This paper presents a system that allows users to implement self-catering,which is extremely convenient and efficient compared to traditional restaurant service.At the same time,the self-help meal system uses automated and modular management,which,contributes to a great reduction of the system maintenance and operating cost,compared to the traditional catering industry.This design of the intelligent dining cabinet includes the master control cabinet system and the storage cabinet control system in the hardware design.The master control cabinet system adopts the industrial control machine as the control part,and is externally connected to a touch screen,a QR code decoders,the GSM / GPRS wireless communication module and the beverage machine control module.The storage grid control system uses STM32 Microcontrollers as the core circuit design,externally connects temperature measuring and control module,storage grid lock module and sterilization module.The communication between the master control cabinet and the storage cabinet control system is in serial port.The software part is divided into master control cabinet control program and STM32 control program.The main control cabinet control program is based on the C# WPF interface development program,specifically including the meal receiving window,delivery window,administrator window and login window.STM32 control program is written in C language,including serial data transmission and analysis,temperature control design,regular sterilization design and door lock control.The system's workflow is that the meal delivery staff put the food into a corresponding storage cabinet of the cabinet,then the orderer can get their food at a self-arranged time.The QR code is used to distinguish different orders.And the QR code corresponds to the storage grid number so that the orderer can use the QR code to take their meal.The significance of this system solve the problem in the delivery part of the traditional model that requires a lot of manpower and time-consuming.While the intelligent dining cabinet which support centralized meal delivery,and it can reduce the wage cost,time-consuming and greatly keep the taste of food.The self-help meal-delivery system allows customers to pick up meals and delivery-staff to send meals at different time,and this system no needs the directly contact between customers and delivery-staff,so it can save the sending costs and simplify the meal-delivery process.The system has good practical value and application value.
