基于WSN的水产品冷链物流实时监测系统

为降低水产品物流损耗、提高水产品冷链物流信息化程度,以ZigBee协议为基础,围绕CC2530型无线传感片上系统,设计了基于无线传感网络(WSN)的水产品冷链物流实时监控系统。系统包括用于采集温度数据的监测节点、用于ZigBee网络组织与数据汇聚的协调器节点和用于实时监测、数据存储和网络控制的远程管理系统。冷链环境系统测试表明监测系统能够应用于水产品冷链物流仓储和运输的全过程,监测节点在变温箱温度-18℃时工作可靠。通信性能测试表明使用-3 dBm射频功率在30 m通信范围内丢包率小于8.4%,节点通信能耗低。

Real Time Monitoring System for Aquatic Cold-chain Logistics Based on WSN

In order to reduce the losses during logistics of aquatic products and improve the informationization level in aquatic products cold-chain logistics,a wireless sensor network(WSN) based on real time monitor system was proposed for aquatic products cold-chain logistics with ZigBee protocol and CC2530 wireless sensor SoC.The system included a sensor node designed for temperature data collection,a coordinator used for data upload and ZigBee network organization,a remote management system developed for cold-chain real time monitor,data storage and ZigBee network control.The system test under cold-chain logistic environment proved that it could be equipped in the whole process of the aquatic products cold-chain and the monitoring node was reliable under-18℃.The communication performance test showed that the node with a-3 dBm RF power achieved a 8.4% or lower packet loss rate within a 30 m communication distance,the energy consumption of data communication was low.
