【摘要】：可追溯系統(tǒng)的主要目的是記錄和存儲產(chǎn)品在供應(yīng)過程中的相關(guān)信息，當(dāng)出現(xiàn)質(zhì)量問題時，能夠快速有效地追查到出現(xiàn)問題的環(huán)節(jié)，實施有針對性的拯救措施，，必要時將產(chǎn)品召回，由此來保障產(chǎn)品的質(zhì)量安全和消費者的知情權(quán)。本文對農(nóng)產(chǎn)品溯源系統(tǒng)的核心技術(shù)問題進行了深入研究，主要內(nèi)容如下： 1.通過查閱相關(guān)文獻，對國內(nèi)外溯源系統(tǒng)的發(fā)展?fàn)顩r進行調(diào)查研究，分析并總結(jié)了我國當(dāng)前農(nóng)產(chǎn)品溯源系統(tǒng)存在的問題，確立了文章研究的主要目標(biāo)。 2.對系統(tǒng)的相關(guān)技術(shù)進行了研究。分析了數(shù)據(jù)庫分布式存儲策略，通過采用基于全局節(jié)點的分配方式提高系統(tǒng)的數(shù)據(jù)查詢速度；著重對QR碼進行了研究，分析了QR碼的結(jié)構(gòu)特點；簡要分析了Web Service的工作原理及工作流程，通過使用開放的標(biāo)準(zhǔn)協(xié)議進行描述、傳輸和交換，提高系統(tǒng)的效率和通用性。 3.本文針對QR碼圖像在實際應(yīng)用中產(chǎn)生的畸變，提出了一種改進型的柱面校正算法，解決了QR碼圖像的桶形失真和枕形失真問題。而對于透視畸變失真，采用較為成熟且可靠的Hough變換法進行校正。在電腦上測試通過后再移植到客戶端，大大提高了開發(fā)效率。 4.通過對農(nóng)產(chǎn)品溯源平臺的功能和性能指標(biāo)、模塊劃分、工作流程、設(shè)計思路等方面的考慮，給出了一個農(nóng)產(chǎn)品溯源平臺的總體解決方案，并通過完善的需求分析和詳細(xì)設(shè)計完成整個平臺的設(shè)計與實現(xiàn)。 5.通過系統(tǒng)測試及試運營，本系統(tǒng)運行穩(wěn)定，各項性能指標(biāo)均符合預(yù)期目標(biāo)，系統(tǒng)的各項功能均滿足應(yīng)用需求。通過在農(nóng)業(yè)生產(chǎn)中使用本系統(tǒng)，可以實現(xiàn)對農(nóng)業(yè)生產(chǎn)、流通過程中的信息管理，提高農(nóng)產(chǎn)品質(zhì)量。
[Abstract]:The main purpose of traceability system is to record and store the relevant information of the product in the process of supply. When there is a quality problem, it can quickly and effectively track down the link of the problem and implement targeted rescue measures. In order to guarantee the quality and safety of products and consumers' right to know, the core technical problems of traceability system of agricultural products are deeply studied in this paper, the main contents are as follows: 1. Through consulting relevant literature, the development of traceability system at home and abroad is investigated and studied, the problems existing in traceability system of agricultural products in China are analyzed and summarized, and the main goal of this paper is established. 2. The related technology of the system is studied, the distributed storage strategy of database is analyzed, and the data query speed of the system is improved by using the allocation method based on the global node; The QR code is studied, and the structure characteristic of QR code is analyzed. The working principle and workflow of Web Service are briefly analyzed, and the efficiency and versatility of the system are improved by using open standard protocol to describe, transmit and exchange. 3. Aiming at the distortion of QR code image in practice, an improved cylindrical correction algorithm is proposed in this paper. The problems of barrel distortion and pillow distortion of QR code image are solved, while the perspective distortion distortion is solved. A more mature and reliable Hough transform method is used to correct it, and then transplanted to the client after passing the test on the computer, which greatly improves the development efficiency. 4. Through the consideration of the function and performance index, module partition, work flow, design idea of the agricultural product traceability platform, the overall solution of the agricultural product traceability platform is given. And complete the design and implementation of the whole platform through perfect requirement analysis and detailed design. 5. Through the system test and trial operation, the system runs stably, all the performance indexes are in line with the expected objectives, and the functions of the system all meet the application requirements. Through the use of the system in agricultural production. Can achieve agricultural production, circulation process of information management, improve the quality of agricultural products.
