Mobile Terminal Device Based On Food Traceability System

In recent years,food safety problems have Appeared frequently,and people’s attention to food safety has increased.With the increase in GDP per capita,people’s demands for food quality have also gradually increased.People are increasingly inclined to purchase higher-quality,safer,and healthier organic green foods,but currently there is no effective food traceability system.It has not yet found a suitable way to establish management of the production behavior of farmers.The rapid development of the mobile Internet has greatly changed people’s lifestyles.The main means for people to go online has shifted from PCs to mobile Internet.Mobile terminal devices such as smart phones and tablet computers have become an integral part of people’s lives.How to establish a farm food traceability system based on mobile terminal equipment is the starting point and end point of all the research in this paper.Based on an in-depth analysis of the status quo and problems of food traceability systems,this paper analyzes the market,users,and feasibility to design a set of Android Apps combined with a minimart to serve the positioning of green farm products companies.The enterprise supervises the farmer’s production behavior,and traces the traceability of the farmer’s food as a whole.The main research work of the thesis is summarized as follows:(1)Android App,which is used to record the growth status of agricultural products,is distributed to farmers through RFID foot rings and equipment.Farmers perform operations such as inputting the growth status of agricultural products on a periodic basis,and ensure that enterprises acquire green agricultural products from farmers.The authenticity.(2)Established a secondary corporate management back office to facilitate enterprises to manage subsidiaries or distributors.(3)A back-end database was established to connect the Android App with the WeChat public platform data.The data returned by the Android App can be directly generated into product details.The system can use RFID as a feature to query the growth process,sales status,and after-sales status of the agricultural product.(4)Focusing on the establishment of a micro-mart that integrates traceability and sales,with the theme of traceability of farm food,using the various interfaces provided by WeChat and the data returned by Android App,to track the growth cycle of the agricultural product on the product details page.,to achieve the purchase,booking and other functions.
