【摘要】：随着肉制品需求不断增加,肉类食品安全问题越发受到人们关注。在传统生产模式中,由于信息采集方法落后、各环节信息衔接不畅等问题,导致肉品信息记录与肉品本身无法有效关联,发生肉类安全问题时难以快速确定事故源头,召回问题食品,缩小影响范围并减少损失。针对现有肉制品生产加工存在环节较多、跨环节信息较难有效关联问题,本课题以雪花牛肉为研究对象,设计一套基于无线传感网的雪花牛肉溯源系统,对从雪花牛养殖到产品销售全过程信息进行采集,实现全程信息有效追溯。主要研究内容:产品溯源编码:通过对雪花牛肉生产实地调研,选取牛耳标号、屠宰编号、产品编号、雪花等级、生产时间等信息加入溯源编码,实现雪花牛肉产品身份编码的唯一性,并将二维条码附在产品标签中。溯源信息采集网络:针对各环节特点,系统分别设计养殖环境节点、运输定位节点、胴体雪花分级节点实现对溯源信息的有效采集。养殖环境节点由CC1101射频模块、微控制器和SHT10传感器等组成,通过SimpliciTI协议组建通信网络采集温湿度等信息;定位节点使用GPS模块对车辆位置实时定位,并通过GPRS无线网络传输数据至远端服务器处理;胴体雪花分级节点通过CCD相机采集胴体眼肌图片,经WiFi传输至上位机,上位机结合图像处理技术对眼肌区域划分,提取大理石花纹含量并对胴体定级,下发结果至终端界面显示。溯源信息数据库:利用SQL SERVER数据库对雪花牛肉溯源数据进行记录,将不同环节数据存储于不同数据表中,通过关键编号对各数据项进行关联,实现溯源信息的交叉查询。溯源信息管理系统:雪花牛肉溯源信息管理系统分为本地软件与Web溯源平台,其中本地软件负责接收节点采集上传的溯源数据,根据数据协议解析数据,存入对应数据库中记录。Web溯源平台主要是响应消费者查询需求,获取溯源编码,查询产品各阶段溯源数据返回用户。系统整体测试情况良好,运行稳定,各环节信息采集节点均能正常工作,稳定采集溯源信息,溯源信息管理软件能正确解析数据并快速响应用户查询需求,返回产品全程信息。系统整体设计为雪花牛肉信息有效追溯提供了一种有效的解决方案。
[Abstract]:With the increasing demand for meat products, people pay more and more attention to the safety of meat products. In the traditional production mode, because the information collection method is backward and the information of each link is not connected smoothly, it is difficult to determine the source of the accident quickly when meat safety problem occurs because of the fact that the meat information record and meat product itself can not be effectively related. Recall problematic foods, narrow down the impact and reduce losses. In order to solve the problem that there are many links in the production and processing of meat products and it is difficult to effectively correlate the information between different links, a traceability system of snowflake beef based on wireless sensor network is designed in this paper, which takes snowflake beef as the research object. The whole process information from snowflake cattle farming to product sale is collected, and the whole process information can be effectively traced back. Main research content: product traceability coding: through the field investigation of snowflake beef production, the information such as ear label number, slaughtering number, product number, snowflake grade, production time and so on are selected to be added to traceability coding. The unique identity code of snowflake beef product is realized, and the two-dimensional bar code is attached to the product label. Traceability information collection network: according to the characteristics of each link, the system designs the breeding environment node, the transportation location node and the carcass snowflake classification node to realize the effective collection of traceability information. The breeding environment node is composed of CC1101 radio frequency module, microcontroller and SHT10 sensor. The communication network is set up by SimpliciTI protocol to collect temperature and humidity information, and the location node uses GPS module to locate the vehicle position in real time. The GPRS wireless network transmits data to the remote server, and the carcass snowflake classification node collects the carcass eye muscle images by CCD camera, and transmits them to the upper computer through WiFi. The upper computer combines the image processing technology to divide the eye muscle area. The marbling content was extracted and the carcass was graded, and the result was displayed to the terminal interface. Traceability information database: using SQL SERVER database to record snowflake beef traceability data, storing different link data in different data table, associating each data item through key number, realizing cross-query of traceability information. Traceability information management system: snowflake beef traceability information management system is divided into local software and Web traceability platform, in which the local software is responsible for collecting and uploading traceability data from the receiving node and analyzing the data according to the data protocol. The Web traceability platform in the corresponding database is mainly to respond to the customer's query demand, obtain traceability coding, and return the traceability data to the user at each stage of the querying product. The whole testing system is in good condition, running stably, all the information collection nodes can work normally, and the traceability information can be collected stably. The traceability information management software can correctly analyze the data and respond to the user's query demand quickly, and return the whole process information of the product. The overall design of the system provides an effective solution for the effective traceability of snowflake beef information.
