【摘要】：近年来,水产品质量安全问题频繁发生暴露了我国在水产品安全问题紧急预警、危机处理以及养殖加工管理机制方面存在着严重漏洞,引起了国内相关监管部门和消费者对水产品质量安全问题的关注,实现水产品生产加工的可追溯已成为国家管理部门和水产养殖加工企业亟待解决的问题。随着条码技术和信息技术应用的逐渐成熟,构建基于条码技术的水产品追溯系统为实现水产品的可追溯性提供了有效手段,本文基于国家项目以某水产养殖加工企业为应用示范,研究国际通用的GS1追溯标准,选择一维条码GS1Databar和二维条码QR Code为追溯信息载体,以水产品养殖阶段和加工阶段各个环节为主线,构建水产品横向和纵向的全方位追溯方式,同时建立以批次为单位的追溯单元,构建批次间的数据关联模型,对水产品的批次号和追溯码的编码方案进行详细设计,并将GS1 Databar和QR Code混合应用于水产品养殖阶段和加工阶段的流程改造,为实现水产品的内部追溯和外部追溯提供具体手段。本论文设计了追溯系统总体方案,构建了面向服务的水产品追溯系统总体架构,设计了水产品追溯系统Web端和水产品追溯手机客户端两种追溯查询终端,并提供追溯条码的实时在线生成打印服务。论文重点研究的关键技术主要包括:1)基于WebService的追溯条码人工生成打印服务技术;2)基于WCF的追溯条码自动生成打印服务技术;3)保障系统安全性的数据加密技术。本文实现了基于手机客户端扫码的追溯查询方式和基于水产品追溯系统Web端的追溯查询方式,并对水产品追溯系统服务端和追溯条码生成打印客户端间的通信模式以及Web服务和WCF服务的接口层和服务层进行了研究,通过采用基于HTTP协议的定时器通信模式实现追溯条码的人工补打,通过采用基于TCP协议的双工通信模式实现追溯条码的实时在线监听打印,保证信息流和实物流的同步,同时从用户登录加密、通信数据加密和追溯QRCode加密三个方面保证追溯信息的真实性和安全性。最后,本文所采用的关键技术在国家项目子课题“基于物联网的水产品生产溯源系统”中得到了实例验证,证明了本文所构建的基于条码技术的水产品追溯系统的有效性,为实现水产品的质量安全追溯提供了一定的借鉴。
[Abstract]:In recent years, the frequent occurrence of aquatic product quality and safety problems has exposed serious loopholes in aquatic product safety emergency warning, crisis management and management mechanism of aquaculture processing in China. The quality and safety of aquatic products are concerned by domestic regulatory authorities and consumers. It has become an urgent problem for the national management departments and aquaculture processing enterprises to realize the traceability of aquatic products production and processing. With the development of bar code technology and information technology application, the establishment of aquatic product traceability system based on bar code technology provides an effective means to realize the traceability of aquatic products. In this paper, based on the national project, an aquiculture processing enterprise is used as an example to study the international standard of GS1 traceability. One-dimensional barcode GS1Databar and two-dimensional barcode QR Code are selected as traceability information carriers. Taking each link of aquatic product breeding stage and processing stage as the main line, the omnidirectional tracing mode of aquatic product horizontal and vertical is constructed. At the same time, the traceability unit with batch as unit is established, and the data association model between batches is constructed. The coding scheme of batch number and traceability code of aquatic products is designed in detail, and the mixed application of GS1 Databar and QR Code in the process transformation of aquaculture and processing stages of aquatic products is carried out, which provides a concrete means for realizing the internal and external tracing of aquatic products. This paper designs the overall scheme of the traceability system, constructs a service-oriented aquatic product traceability system architecture, and designs two kinds of traceability query terminals, the aquatic product traceability system (Web) and the aquatic product traceability mobile phone client. And provides the real-time online generation printing service of traceable bar code. The key technologies of this paper mainly include: (1) tracing barcode manually generated printing service based on WebService (2) tracing barcode automatic generation printing service based on WCF (3) data encryption technology to ensure the security of the system. In this paper, the way of tracing query based on mobile phone client and Web based on aquatic product traceability system is realized. The communication mode between the server end of aquatic product traceability system and the generating and printing client of traceability bar code, as well as the interface layer and service layer of Web service and WCF service are studied. By adopting the timer communication mode based on HTTP protocol to realize the manual patching of traceback bar code, and adopting the duplex communication mode based on TCP protocol to realize real-time on-line monitor and print of traceback barcode, the synchronization of information flow and physical flow is ensured. At the same time, the authenticity and security of traceability information are ensured from three aspects: user login encryption, communication data encryption and traceability QRCode encryption. Finally, the key technologies used in this paper are verified by examples in the national project subproject "Aquatic Product traceability system based on the Internet of things", which proves the effectiveness of the aquatic product traceability system based on bar code technology. It provides some reference for realizing the quality and safety tracing of aquatic products.
