Design And Development Of Intelligent Water Reservation Device And Information System

With the continuous development of science and technology and the improvement of people's living standards,more and more smart home devices are beginning to enter people's life.Bottled drinking water is widely used in families and offices because of its low price and drinking convenience.However,the reservation and distribution of the large quantity of bottled drinking water is still used in manual operation.The process is tedious and the efficiency is not high.Therefore,it is necessary to design and develop an automatic,intelligent water reservation device and an efficient information system.Firstly,the paper studies embedded,information acquisition and wireless network transmission technologies.Secondly,we design and implement an intelligent water reservation device and information system through analyzing the functions and performance requirements of the intelligent water reservation device and information system.Intelligent reservation device is mainly composed of ARM processor,water detection module,wireless network transmission module,LCD module and other hardware modules,it is used to make the remaining quantity detection of bottled drinking water and realized the function of sending"reservation" request.The information system consists of two parts:the client mobile application and the information system of the selling company.When the amount of water is insufficient,the wireless transmission module controlled by the ARM processor to automatically send the "water reservation" request information to information system of the selling company.At the same time,it also supports users to realize autonomous remote purchase of water through mobile application.Information system of the selling company will generate order to return to the user after receiving the request of the water reservation,and generate the delivery order to delivery staff after the user to confirm,after confirmation of the delivery staff,the distribution information will be sent back to the user,and finally the intelligent water reservation and automatic delivery of the company will be realized.The paper adopts STM32F103RBT6 processor,full bridge circuit,HX711 A/D conversion circuit,ESP8266 WIFI circuit,key circuit and LC1602 liquid crystal display circuit and other hardware circuits to realize intelligent water reservation device.Using the Java language to develop mobile APP for clients.Using C#development language and MySQL as the database,the information system of the selling company was developed on the Visual Studio 2013 platform.Through the experimental test,the intelligent water reservation device can collect the effective information of the residual amount of the bottled drinking water in time,and accurately send the "water reservation" request information and other functions.The mobile application can realize user registration,user login,remote ordering of water and information display.Information system can realize user information management,employee information management,order information management and other management functions.
