Design And Implementation Of Data Management And Service Based On The System Of Fruit Quality Testing

With the development of society and economic,People's requirements for the quality of life is more and more high,the traditional way of life can't satisfy the life of modern people.Meanwhile,fruit is an indispensable part of life,the quality of fruit will be more concentrated on.At present,most of fruit quality testing products are large equipments.These equipments can achieve the goal of testing fruit quality,but they are too expensive,which is not suitable for ordinary residents and small and Medium Enterprises.Meanwhile,because of the problem of the equipment itself,they are not convenient to carry with people.With the development of the Internet,the network has become an indispensable part of the life.This subject is a fruit quality data management and service platform for a portable hand-held fruit testing device to manage the quality of thin epidermis fruits.There are a large number of data to analyse by accumulating data.A large of number different fruit's qualities are presented to people through a computer by Internet.Meanwhile,people can check fruit through mobile phone by themselves.This subject will be combined with the concept of software humanization and ana lysis of the existing functions of similar software,and analyze the principle of its co mposition.Combined with knowledge of financial management and software engineerin g knowledge,the system is divided into the following parts: system configuration,data management,fruit detection,data service and data import.In the realization of Technology,the system designed and implemented in this paper is based on J2 EE Technology.Using Spring and Mybatis are as the management of the project and the development of the persistence layer.The front page uses the HTML5,JQuery,JavaScript and other web technologies to obtain the data submitted by the user and display the data in the database.Using Ajax to realize the interaction between the front page and the server.The mobile terminal uses Android as a development platform,using HTTP protocol to interact with the server to implement the following functions:(1)Designing of server and management system,at the same time,it provides data service and data import function in management system.(2)According to the MLR,the algorithm is implemented by coding at server;(3)APP receive infrared spectrum data by connecting with portable handheld fruit detection device with bluetooth;(4)The designing of APP,achieving the function of fruit testing with algorithm by connecting to server;(5)The infrared spectrum data and the detected fruit quality data are stored and managed.Multiple linear regression equations are continuously improved through the accumulation of data,which makes the measurement results more accurate.
