基于低功耗传输方法的设施花卉环境监测系统
为了降低现有设施环境监测系统中传感节点的能耗,延长无线传感网络的生存周期,该文提出了节点动态组包主动传输和多种环境变量加权控制传输2种低功耗机制,减少了大量重复冗余数据的传输,并实现了基于Zigbee的设施花卉环境监测及其低功耗传输系统。节点以CC2430芯片为核心,并根据影响花卉生长的环境参数,同时装载SHT10温湿度传感器、BH1750FVI光照传感器以及COZIR二氧化碳传感器,因此节点可同时采集传输多种环境参数,降低了硬件成本。在南农大园艺试验基地进行组网测试,试验结果表明,系统比传统周期传输节点(周期1min)的能耗减少85.97%,测量精度在98.5%以上,网络平均丢包率为0.84...

| Summary: | 为了降低现有设施环境监测系统中传感节点的能耗,延长无线传感网络的生存周期,该文提出了节点动态组包主动传输和多种环境变量加权控制传输2种低功耗机制,减少了大量重复冗余数据的传输,并实现了基于Zigbee的设施花卉环境监测及其低功耗传输系统。节点以CC2430芯片为核心,并根据影响花卉生长的环境参数,同时装载SHT10温湿度传感器、BH1750FVI光照传感器以及COZIR二氧化碳传感器,因此节点可同时采集传输多种环境参数,降低了硬件成本。在南农大园艺试验基地进行组网测试,试验结果表明,系统比传统周期传输节点(周期1min)的能耗减少85.97%,测量精度在98.5%以上,网络平均丢包率为0.84%,满足了对设施花卉环境的有效监测及低功耗传输的要求。 |
