Design And Implementation Of Quality Safety Traceability System For Agricultural Products

In recent years,due to the quality and safety of agricultural products caused by frequent accidents,People's Daily diet and life has caused a serious impact,and caused the relevant departments of the provinces and cities of the country to pay great attention.Heilongjiang province is our country agriculture big province,produce sells to the whole country,grain crop is more famous,its quality safety problem is particularly important.In order to further improve the production quality of agricultural products and ensure the quality and safety of agricultural products,heilongjiang province requires the design and implementation of the traceability cloud platform for agricultural product quality and safety.This article through to the heilongjiang province that is suihua biotechnology research unit,refer to a large number of relevant literature,research at home and abroad about traceability system construction,analyzing the characteristics of the traceability system,at the same time to our country at present the traceability system for comparative analysis,summarizes the problems existing in the traceability system and the insufficiency,then solve and make up for,to the quality and safety of agricultural products traceability system to carry on the design and implementation.The main work of the system design and implementation in this paper is as follows:(1)analyze the traceability process of agricultural products.Summarize and summarize the previous research results,analyze the whole process of traceability system to lead to the key links,including agricultural production links,quality supervision links and key data processing,and explain the way to realize the traceability of agricultural products in this paper.The key data information in the traceability results of agricultural products were screened to ensure the traceability effect.(2)design the traceability method of agricultural products.According to the requirements of the traceability system,the traceability effect of this paper is realized in two ways,through two-dimensional code traceability and source tracing.In this paper,QR Code is adopted as the way to realize two-dimensional Code to explore the realization process of two-dimensional Code,and the two-dimensional Code error correction algorithm and mask operation are explained.For the backtracking code design,reference to the existing code for optimization and innovation,combined with the production requirements,screening key data message coding design,at the same time,custom encryption algorithm design,to avoid the leakage of coding rules.(3)design the key data verification method.This paper puts forward the possibility of false information behavior in the traceability data,designs the verification rules of key data collection and information audit,determines the production time and place by obtaining EXIF information of agricultural photos,adds the information in watermark,and verifies it with the specified location and time to ensure the authenticity of the data.For the agricultural inspection audit information,add the audit results and related responsible person information as the watermark processing results,so as to facilitate the timely accountability and treatment of agricultural products.Two kinds of data checking methods ensure the authenticity and effectiveness of traceability data.(4)Design and implement system development process.Based on the analysis results of the traceability process of agricultural products,this paper divides the traceability process into four modules:producer,supervisor,consumer and system manager.Develop the entire system by developing the capabilities of each module.For the construction of traceability system,according to the development idea of software engineering,the demand analysis,function design and system realization are carried out respectively.Finally,the traceability system was tested,including black box test and performance test,to ensure the stable operation of the system.
