【摘要】：在我国居民日常食品消费中,果蔬类农产品占据的比重逐年增加。然而,问题黄瓜、染色花椒和毒豆芽等事件引发了公众对果蔬类农产品质量安全的担忧。果蔬冷链断链,食品安全检测不到位,市场监管不力等原因均导致果蔬类农产品安全问题频发。为了进一步稳定果蔬类农产品市场秩序,确保果蔬质量安全,实现果蔬类农产品冷链物流信息溯源是食品安全机制的关键环节,也是食品安全管理的必然趋势。通过信息溯源,可以准确获取果蔬类农产品在供应链各环节上的生产信息、加工信息和流通信息等,实现果蔬类农产品全程流通透明化。本文就果蔬类农产品溯源模式、溯源关键技术及溯源系统总体设计这几个方面展开研究。首先,由于果蔬类农产品流通渠道复杂,研究选取典型的三种流通模式即“农贸市场流通模式”、“龙头企业主导的农超对接流通模式”和“电子商务流通模式”,应用流程分析方法,优化果蔬类农产品冷链物流业务流程,参照HACCP、GAP和现有的果蔬安全相关标准,筛选出冷链物流各环节的过程溯源指标和安全溯源指标。其次,研究根据果蔬类农产品具有较高的温度敏感性,应用改进的拉依达准则和自适应数据融合方法,建立基于时间—空间的冷链物流温度数据融合模型,提高温度数据融合精度。最后,研究根据果蔬类农产品冷链物流信息溯源需求,应用系统分析方法,对果蔬类农产品冷链物流信息溯源系统进行总体设计。本文的主要结论包括:(1)提出了果蔬类农产品冷链物流信息溯源模型,该模型确定了以流转信息为主的过程溯源指标和果蔬质量关键信息为主的安全溯源指标,为果蔬类农产品冷链物流信息溯源系统的总体设计奠定基础(2)建立基于时间—空间的冷链温度数据融合模型,修正了误差较大的传感器,实验证明,该算法与平均值算法相比,提高了数据融合精度。(3)设计了果蔬类农产品冷链物流信息溯源系统,提出每种溯源模式的溯源系统设计需求,实现果蔬类农产品冷链物流信息的记录与查询,规范各环节主体行为,提高果蔬类农产品的安全水平。
[Abstract]:In the daily food consumption of our country, the proportion of fruit and vegetable agricultural products is increasing year by year.However, problems with cucumbers, peppers and bean sprouts have raised concerns about the quality and safety of fruits and vegetables.The cold chain breakage of fruit and vegetable, the food safety detection is not in place, the market supervision is weak and so on, which lead to the frequent safety problems of fruit and vegetable agricultural products.In order to further stabilize the market order of fruits and vegetables and ensure the quality and safety of fruits and vegetables, it is the key link of food safety mechanism and the inevitable trend of food safety management to realize the traceability of cold chain logistics information of fruits and vegetables agricultural products.By tracing the source of the information, we can accurately obtain the production information, processing information and circulation information of the fruits and vegetables agricultural products in each link of the supply chain, so as to realize the transparency of the whole course of the circulation of fruits and vegetables agricultural products.In this paper, the traceability model, the key technology of traceability and the overall design of traceability system are studied.First of all, due to the complexity of the distribution channels of fruits and vegetables, the study selects three typical circulation modes, namely, "the circulation mode of farmers' market", "the mode of agricultural super docking circulation led by leading enterprises" and "the mode of electronic commerce circulation".The process traceability index and safety traceability index of each link of cold chain logistics were selected according to HACCPGAP and the existing standards of fruit and vegetable safety by using the method of process analysis to optimize the business process of cold chain logistics of fruits and vegetables.Secondly, according to the high temperature sensitivity of fruits and vegetables, an improved Laida criterion and adaptive data fusion method are applied to establish the temperature data fusion model of cold-chain logistics based on time-space.Improve the precision of temperature data fusion.Finally, according to the demand of cold chain logistics information traceability of fruits and vegetables, the system of cold chain logistics information traceability of fruit and vegetable agricultural products is designed by system analysis method.The main conclusions of this paper include: (1) A cold chain logistics information traceability model for fruits and vegetables is proposed, which determines the process traceability index based on the flow information and the safety traceability index based on the key information of fruit and vegetable quality.For the general design of the cold chain logistics information traceability system of fruits and vegetables, the paper establishes the fusion model of temperature data of cold chain based on time and space, and corrects the sensor with large error. The experimental results show that the algorithm is compared with the average value algorithm.Improved the precision of data fusion. 3) designed the cold chain logistics information traceability system of fruit and vegetable products, put forward the design requirements of each traceability model, and realized the record and query of the cold chain logistics information of fruits and vegetables agricultural products.Standardize the behavior of the main body of each link, improve the safety level of fruits and vegetables agricultural products.
