| 摘 要： | 针对温室测控系统信息传输技术存在的一些问题,根据温室结构特征提出一种动态星型无线传感器网络的框架,从低成本低功耗角度出发,移动的汇聚节点采用定时跳频方法与子节点形成子网,以尽量缩短点对点之间的通信距离。利用帧扩展的方法实现了以低功耗芯片nRF2401A构成复杂的通信网络,并给出了传感器节点、控制节点和汇聚节点的通信算法。在汇聚节点不同的工作状态下,对网络子节点进行能耗分析,结果表明,动态星型无线传感器网络的通信方法具有很好的节能效果,对温室中数据的传输是有效的。

| Abstract: | Regarding problems of information transmission technology for greenhouse measuring and controlling system,a dynamic star wireless sensor network was proposed according to greenhouse structure.In view of cost-effective and low energy consumption,frequency hopping timing methods were combined with sub-nodes to form sub network for mobile aggregation node,which reduces point-to-point traffic span as much as possible.Using frame extension method,complex communication network was achieved based on the low energy consumption chip,nRF2401A.Communication algorithm is introduced for sensor nodes,control nodes and aggregation nodes.Energy consumption of sub-nodes within network was analyzed under different working conditions of aggregation nodes.Research results indicate that communication method of dynamic star wireless sensor network saves energy effectively,and data transmission is effective. |
