Design And Implementation Of Quality And Safety Traceability System For Agricultural Products

In recent years,accidents caused by the quality and safety of agricultural products have frequently occurred,which have brought great adverse effects on society and consumers.As a result,the safety of agricultural products has received special and extensive attention from government and enterprises.The agricultural products in Guizhou Province are mainly based on economic crops,which have high economic value,sosafety issues are worthy of consideration by people at all levels.Therefore,it is an urgent task to design and establish a platform for quality and safety traceability of agricultural products to further improve the growth quality of agricultural products and avoid the safety problems caused by the quality of agricultural products.In this paper,the relavant requirements of Qingzhen vegetable and tea base were investigated,hundreds of literature and the traceability system built at home and abroad as well as the traceability system platform were studied.Then a quality safety traceability system platform for agricultural products has been designed and established to solve the problems and shortcomings.This paper has carried on detailed requirement analysis and system design to the system,adopting Spring MVC frame to realize the system,using Webftlet technology in Web GIS to realize plot division and information management;Applying the mobile terminal or the Web end to collect farming operation picture data in real time.Using the QR Code in the two-dimensional code to solve the tracing method problem,accessthe corresponding links by parsing QR code and render traceability results according to the retroactive code.In order to solve the problem of data authenticity,obtain the real time and place to display to the consumer by parsing the EXIF information of the agricultural operation pictures.At the same time,to solve the error correcting ability of two-dimensional code,the error correction algorithm and mask algorithm of QR Code were studied in depth in this paper.And the graphic display of the data statistics result was achieved by High Charts.The system platform studiedthe trace of consumers,the management of producers,and the control of supervisors.The consumers can retrospectively obtain agricultural product,producer and consumer evaluation data information through traceability codes or two-dimensional codes.The producers collect data on agricultural public opinions and growth processes in real time and monitor them for digital management.The supervisor establishes a quality safety supervision and management center,publishes relevant policies and regulations,reviews agricultural inspection and certification reports,and realizes the purpose of digital quality supervision.
