Design Of Intelligent Beverage Distribution Vending Machine Information Management System

With the development of times,a large number of automation produ cts emerged.The vending machine is one of the common automation products in life.It be used all over the world because of it's practical advantages.Bu t the function of vending machine on the market is just selling items.The pr ovider knows nothing about user's purchase preference,frequency,time,place and related data.Therefore,the provider can't supply better items and services to customers,and lack of items.So this article made the following research through the shortcoming of the vending machine on the market.(1)Establishing a rounded system to collect user data by MongoDB data base,Node.js language and Javascript language.The main collection is as foll ows: shopper,shopping details,shopping time,shopping location.(2)Real-time monitoring of inventory availability.The main workflow: Ev ery time the user's payment process ends,the system will use the moving ave rage method to obtain the average value of the goods sold in 30 days,and c ompare the average value with the current cargo storage,so as to monitor wh ether the cargo balance can be real-time support sales at the next moment.(3)Payment function.This article use the Websocket protocol,and seal t he Websocket and socket.io.It can be quickly done the payment by this joint.(4)Data visualization component.The component ideas: The overall struct ure of a component is divided into a parent class and a child class.The pare nt class defines the common attributes and the implementation of the custom algorithm.The child class inherits the common attributes and uses the specific attributes to draw a specific graphic through the canvas technical guide.Finally,through the combination of RS232 communication technology and the lower computer,a complete intelligent beverage dispensing machine is formed.
