摘要
综合有线和无线传输系统的优点,构建基于无线传感器网络的新型仓储粮情温湿度监测系统体系.整个无线传感器网络监测系统根据仓库数量及分布划分成若干相对独立的传感器网络,每个相对独立传感器网络通过各自主族节点和网关接口,与仓库外现场总线相连,把传感器节点监测到的数据传输到仓储监测管理中心.重点讨论一个适合在仓储粮情监测的无线传感器网络的拓扑控制、网络通信协议及与现场总线互联等关键技术问题.
A system structure on grain storages monitoring system based-on wireless sensor network and CAN bus is set up.The whole wireless sensor network is divided into some relatively independent networks according to the location of storages.The main cluster node of each relatively independent network transmits the grain temperature data from the other nodes to the CAN bus outside the grain storage via gateway.The paper provides the related theory and key technologies,which focuses on the effective topological structure and communication protocol of WSN in the grain storage monitoring system.
