【摘要】 我国对中药材的研究与使用可追溯至数千年前,天然资源物种庞大。但是,随着自然环境的破坏,人们肆意的掠夺式采集和灭绝性捕猎使得野生、天然的优质中草药数量呈现大幅度下滑趋势,鱼龙混杂的劣质中药材充斥着整个市场。随着人们安全意识的提高和当下较为混乱的市场现象,消费者加大了对药品质量安全等问题的关注力度。本文从硬件、算法、软件三方面对道地中药材质量追溯系统进行研究设计。将无线传感器节点与RFID标签阅读器相结合。在整个供应链过程中减缓RFID采集上传的压力,提高了工作效率和准确性。数据碰撞是大量数据上传不可避免的困扰,本文对RFID防碰撞算法进行了改进,使改进后的算法更加适用于标签数量多,分布面积广的情况。数据通过ZigBee网络节点上传到服务器端时也会面临数据大量堵塞的情况,结合蚁群算法的AODV路由协议能够按照信息素量、路由跳数等影响因子合理科学的分配ZigBee路由节点路径。降低路径选择拥塞度,提升路径利用率。文章构建了追溯系统总体框架,对相关硬件进行了性能测试。并在应用层利用B/S架构搭建质量追溯系统,实现了对用户、标签、供应链模块等环节的管理,为消费者和管理人员提供了可操作化追踪。理论与实践紧密结合,为项目加入更多实际意义。本文创新点主要概括为以下三方面:1、在系统硬件设计中将RFID技术与ZigBee技术相融合,弥补了单纯使用RFID技术在采集过程中存在的片面性和冗余性等问题。2、本文依照改进后的RFID防碰撞算法和基于蚁群算法的AODV路由协议为项目设计实施提供了相关依据。最大程度减少了碰撞传输损失,运用蚁群算法对路由节点的路径选择进行优化。3、搭建完成了较为完善的质量追溯系统,以五大模块的形式对药材生产加工等所有环节进行系统性管理。更多还原

【Abstract】 China’s research and use of Chinese herbal medicines can be traced back thousands of years ago,the natural resources of a large species.However,with the destruction of the natural environment,people wantonly predatory harvest and extinction hunting makes the wild,natural quality of Chinese herbal medicine showed a significant decline in the number of trends.With the improvement of people’s safety awareness and the current chaotic market phenomenon,consumers pay more and more attention to medicine safety and quality problems.This article research and designs the traceability system of authentic Chinese herbal medicine from three aspects:hardware,algorithm and software.Combine wireless sensor nodes with RPID tag readers.In the entire supply chain process to reduce the pressure of RFID upload,improve work efficiency and accuracy.The data collision is a kind of unavoidable troubles in the data upload.In this article,the RFID anti-collision algorithm is improved,so that the improved algorithm is more suitable for the case of large number of tags and wide distribution area.Data through the ZigBee network node upload to the server side will also face a large number of data blockage,The AODV routing protocol combined with the ant colony algorithm can allocate the ZigBee routing node path according to the factors such as the amount of pheromone,the number of hops,and so on.Reduce path selection congestion level and increase path utilization.The article constructs the overall framework of the traceability system and performs the performance test on the related hardware.In the application layer using B/S architecture to build quality traceability system,To achieve the user,label,supply chain module and other aspects of the management.for consumers and managers to provide operational tracking.Theory and practice closely,for the project to add more practical significance.The innovation of this paper is summarized as follows:1、In the system hardware design RFID technology and ZigBee technology integration,make up for the simple use of RFID technoloy in the acquisition process of the one-sidedness and redundancy and other issues.2、This paper provides the relevant basis for the design and implementation of the project according to the improved RFID anti-collision algorithm and the AODV routing protocol based on ant colony algorithm.Which minimizes the collision transmission loss and uses the ant colony algorithm to optimize the routing choice of the routing node.3、Set up a more complete quality traceability system,the form of five modules on the production and processing of medicinal herbs and all other aspects of systematic management.更多还原
