无线传感器网络在热链物流中的实例分析与展望

本文以冷链物流为对照引入热链物流新概念,介绍热链物流产生的背景和无线传感器网络技术应用背景,以冬季花卉的种植与运输为实例分析无线传感器网络在整个热链物流活动中的应用。研究者对于花卉生长环境和运输环节中的环境因子的采集与数据传输是独立分开的,并且多数研究重点放在传感器低耗的设计,环境信息参数的监控等。本文以热链物流为主线对整个花卉热链活动环境监控系统进行设计,并增添了无线传感器网络的反馈环节,以便在花农不便时系统快速准确得做出调整措施。分析发现无线传感器网络在花卉热链物流中存在的主要问题是功耗大、通信能力有限以及应用的成本较高,对存在的问题提出相应的建议,并指出为了培育更优质的花卉,生理传感器节点的设计与应用是新方向。

基于WSN的冬季蔬菜热链物流应用设计

WSN技术集信息感知、采集、处理于一体,具有灵活、精准、便捷等优点。本文对蔬菜冬季储运环境分析后,针对在冬季运输中极易发生冻害、腐烂损耗的部分蔬菜进行研究,以其整个物流活动的运输、装卸、储存为主要环节,利用WSN技术,通过对关键的温湿度控制进行热链物流的应用设计,以期更好地监控整个流程,减少物流损耗,增加物流效益。并分析了在实际应用中的瓶颈,及对未来推广应用的展望。

Construction and Implementation of Logistics Tracking Management System of Tropical Agricultural Products Based on Supply Chain

[Objective] The paper is to construct the logistics tracking management system of tropical agricultural products based on supply chain.[Method] With tropical agricultural products in Hainan as study object,based on logistics supply chain files and electronic tag coding of agricultural products,cold chain temperature and humidity monitoring,vehicle transportation positioning,data exchange of XML Web services and role-based permission dynamic allocation,the multi-level multi-permission and multi-role logistics tracking management system of tropical agricultural products has been established.[Result] The system constructs information exchange platform for various links of logistics supply chain of tropical agricultural products,which realizes the entire quality monitoring and information tracing of agricultural products,thus enhancing the competitiveness of supply chain in company.[Conclusion] The system has good application and extension prospect.
