Design And Implementation Of Fruit And Vegetable Quality And Safety Traceability System Based On Android

In our country,agriculture is the fundamental industry of the national economy,agricultural products and its processing enable to stimulate the development of agriculture in the Chinese agricultural economy well,particularly play an important role in the national economy.With the implementation of Chinese reform and opening-up policy,people's conditions of material life constantly improve,and people pay more attention to safety problem of agricultural products,especially in recent years,some safety accidents of agricultural products appear frequently,and there is no exception in fruits and vegetables.A series of quality safety problems of fresh agricultural products,like excessive amount of pesticide residue,make consumers full of anxiety,so that the consumers ' design on knowing traceability information of product become more intensive.With the rapid development of information technology,agricultural informatization has also received rapid development,the agricultural products traceability system is born at the right moment,the manufacturing and other process information satisfy the consumer's right to know the great satisfaction,at the same time,increase their confidence and sense of security in agriculture and agricultural products market.At present,there have been many agricultural products traceability systems in China,which can provide some basic production information for the consumers,but there are still some problems in these informations for ordinary consumers,like rough and indirect traceability information.This research issue is proposed for these problems.The research starts from the angle of consumers,takes fruits and vegetables as tracing object,studies the design and realizes Android-based quality safety traceability system of fruit and vegetable.In earlier stage,adopt literature research method to review and arrange related domestic and foreign literature about quality safety traceability of agricultural products,studies relative current situation and existing agricultural product of the practical technology of existing quality safety traceability system.After early theoretical work,determine the systematic function to be realized.In this study,take Android as development platform,adopt SQLite database,take QR Code as retrospective port,display basic information through scanning recognition method,take Baidu map as a window,directly display view information of producing area,and design a systematic retrospective process,including main interface display,QR Code scanning recognition,basic information acquisition,graphical positioning of producing area,detailed tracing information and consumer feedback.
