【摘要】：蔬菜是我国重要的农产品,也是我国城乡居民不可缺少的食物来源。随着我国经济的不断发展和人们生活水平的不断体高、蔬菜食用量不断增加,传统的以数量为追求的食品欲望已经不是现在人们的目标了,人们对食品的品质、卫生状况、质量、营养、健康和营养均衡等性能越来越注重。然而,一些商家为了追求眼前的利益,对蔬菜质量把关不严,导致了大量食品安全事件的发生。近年来频频曝光的毒豇豆、毒韭菜、毒豆芽等事件,严重影响了人们群众的饮食健康,食品质量安全问题已成为人们日常生活担心的问题。在这种蔬菜质量安全十分严峻的环境下,蔬菜质量追溯系统应运而生。本文以"首都农业集团农产品全产业链物流信息服务平台建设"项目为基础,应用物联网技术进行蔬菜质量追溯系统的设计与实现。本文将每种蔬菜种植过程作为一个工艺流进行了规划。在每批蔬菜的种植前,根据蔬菜的工艺流制定了生产计划,对蔬菜的种植过程中的每个农事操作的时间点和操作步骤都进行了严格设定。在农事操作工具上贴上RFID标签,应用RFID技术、传感技术再根据蔬菜的生产计划则可以实现蔬菜种植过程中农事操作信息的自动采集。蔬菜生产工艺的制定以及蔬菜生产计划的制定都有益于蔬菜质量追溯的进行以及蔬菜种植过程的标准化。本文应用GSP技术、温湿度传感器以及无线传感技术,对蔬菜物流过程中的位置信息、温度和湿度进行了采集,应用二维码技术,将采集的信息以二维码的形式向消费者提供查询途径。为了更好的控制菜的质量,本文应用支持向量机的分类回归预测模型对蔬菜的生产地块进行分类预测,以蔬菜种植地块的"土壤污染度"和地块中蔬菜的"农药残留量"作为分类指标,将地块分为"重点关注"和"非重点关注"两类。对于预测结果为"重点关注"的地块,生产基地管理员可对这类地块进行重点关注。本文研究的基于物联网的蔬菜质量追溯系统能够实现蔬菜的种植到销售整个过程质量信息的自动采集与溯源功能。本文研究的蔬菜质量追溯系统不仅能实现消费对蔬菜质量信息的需求而且可以提高蔬菜生产基地的管理效率,为蔬菜生产基地的标准化作业提供参考。
[Abstract]:Vegetable is an important agricultural product and an indispensable food source for urban and rural residents in China. With the continuous development of our economy and the continuous improvement of people's living standards, the amount of vegetables consumed has been increasing. The traditional desire for food with quantity as the pursuit is no longer the goal of people now. People have a sense of food quality and hygiene. Quality, nutrition, health and nutritional balance are more and more important. However, in order to pursue the immediate benefits, some businesses are not strict on the quality of vegetables, leading to a large number of food safety incidents. In recent years, the frequent exposure of toxic cowpea, poisonous leek, toxic bean sprouts and other incidents seriously affected the people's diet health, food quality and safety has become a daily concern of people. In this kind of vegetable quality safety environment, vegetable quality traceability system arises at the historic moment. Based on the project of "Construction of Logistics Information Service platform for the whole Industry chain of Agricultural products of Capital Agricultural Group", the design and implementation of vegetable quality traceability system based on Internet of things technology is presented in this paper. In this paper, each vegetable growing process is planned as a process flow. Before each batch of vegetables was planted, the production plan was worked out according to the technological flow of vegetables, and the time points and operation steps of each agricultural operation in the process of planting vegetables were strictly set. Attaching RFID label to agricultural operation tools, applying RFID technology and sensing technology can realize the automatic collection of agricultural operation information in vegetable planting process according to vegetable production plan. The establishment of vegetable production process and vegetable production plan are beneficial to the traceability of vegetable quality and the standardization of vegetable planting process. In this paper, GSP technology, temperature and humidity sensor and wireless sensor technology are used to collect the position information, temperature and humidity in vegetable logistics process. The collected information is provided to consumers in the form of two-dimensional code. In order to control vegetable quality better, this paper uses the support vector machine (SVM) classification regression prediction model to forecast vegetable production plots. The soil pollution degree of vegetable planting plots and the pesticide residues of vegetables in plots were taken as the classification indexes, and the plots were divided into two categories: "focus attention" and "non-key concern". For the sites where the forecast result is "focus", the production base administrator can focus on this kind of land. The vegetable quality traceability system based on the Internet of things in this paper can realize the automatic collection and tracing function of the quality information in the whole process of planting and selling vegetables. The vegetable quality traceability system studied in this paper can not only meet the demand of consumption for vegetable quality information but also improve the management efficiency of vegetable production base and provide a reference for the standardized operation of vegetable production base.
