【摘要】：RFID具有简单实用、应用灵活、适应恶劣环境等特点,广泛应用食品安全、物流、交通等众多领域,但RFID标签的高成本却制约其在食品安全溯源系统中应用。有机RFID在具备二维条码廉、柔、薄等特点的同时,又保存了无机RFID标签准确、易用、抗干扰、适用恶劣条件等大部分优点。本文以有机RFID技术为基础,提出了基于有机RFID的溯源系统。大米交易环节繁多,每个环节都有可能导致运送袋上的条形码与大米信息数据不对应,由此带来的大米串货现象非常普遍。另外,大米交易环境恶劣,装订在大米运送袋的条形码容易损坏和脱落,致使大米信息丢失,从而使大米追溯无从着手。因此,将RFID技术应用于大米产品供应链,实施有效的跟踪和追溯,建立安全、可靠、准确度高的大米供应链溯源系统势在必行。结合有机RFID的特点和大米行业特色,将有机RFID识别新技术引入大米溯源系统。对比分析了ALOHA算法、时隙ALOHA算法、二进制搜索算法和跳跃式二进制树形算法的优缺点,提出在有机RFID中应用跳跃式二进制树形反碰撞算法,从而优化了有机RFID的性能,实现有机RFID在大米供应链中大范围应用。在深入研究大米溯源系统基本原理的基础上,结合有机RFID技术的功能,针对目前追溯系统的不足及其精确度有待提高的要求,将溯源树算法应用于大米的加工子系统记录和区分大米产品的信息数据,并利用溯源查找算法对整个大米供应链各环节找出损坏或者丢失溯源信息数据。同时,提出关联网模式从而使大米稻田信息、加工信息、仓储信息、配送信息以及销售信息统一关联,有效解决了运送袋上的条形码与大米信息数据不对应而带来的大米串货现象。针对现有溯源系统的局限和不足,依据大米行业种植、生产、加工和销售各个环节的具体特点,把溯源系统分解为种植子系统、加工子系统、配送子系统、销售子系统和消费者子系统,设计出溯源系统各个子系统的具体模型,针对各环节合理的应用有机RFID技术,使溯源信息数据的条理性和模块化,快速、准确实现大米的跟踪和追溯,提出了适合大米的供应链的溯源系统。
[Abstract]:RFID has the characteristics of simple and practical, flexible application, adapt to harsh environment, widely used in many fields such as food safety, logistics, transportation, etc. However, the high cost of RFID label restricts its application in food safety traceability system. Organic RFID not only has the characteristics of two-dimensional bar code, such as cheap, soft and thin, but also keeps inorganic RFID tag accurate, easy to use and anti-interference. Based on organic RFID technology, a traceability system based on organic RFID is proposed. There are so many links in the rice trade that each link may cause the barcode on the delivery bag not to correspond to the rice information data, and the resulting rice string is very common. In addition, the rice trading environment is bad. The bar code that binds to the rice delivery bag is easy to damage and fall off, resulting in the loss of rice information, which makes rice traceability impossible. Therefore, the application of RFID technology in rice product supply chain, effective tracking and traceability, and the establishment of safety, Reliable and accurate rice supply chain traceability system is imperative. Combined with the characteristics of organic RFID and the characteristics of rice industry, this paper introduces the new technology of organic RFID recognition into rice traceability system. The advantages and disadvantages of ALOHA algorithm, slot ALOHA algorithm, binary search algorithm and jump binary tree algorithm are compared and analyzed. A jump binary tree anti-collision algorithm is proposed in organic RFID to optimize the performance of organic RFID and to realize the wide application of organic RFID in rice supply chain. On the basis of deeply studying the basic principle of rice traceability system, combined with the function of organic RFID technology, aiming at the deficiency of the current traceability system and the requirement of improving its precision, The traceability tree algorithm is applied to the processing subsystem of rice to record and distinguish the information data of rice products, and the traceability search algorithm is used to find out the damaged or lost traceability information data of the whole rice supply chain. In this paper, the associated network model is put forward to unify the information of rice paddy field, processing information, storage information, distribution information and sales information, which effectively solves the problem of rice bunching caused by the lack of correspondence between the barcode and the rice information data on the delivery bag. In view of the limitations and shortcomings of the existing traceability system, according to the specific characteristics of the rice industry, such as planting, production, processing and marketing, the traceability system is divided into planting subsystem, processing subsystem and distribution subsystem. The specific models of each subsystem of traceability system are designed for the sales subsystem and consumer subsystem. The organic RFID technology is applied reasonably to each link, which makes the traceability information data orderly and modularized. The traceability system of supply chain suitable for rice is put forward.
