摘　　要：针对大规模农田应用中传感器无需不间断采集和上传数据的场景,在无线、多跳自组织网络簇首轮换机制的网络结构基础上,提出节点能耗状态机。从单一节点自身能耗出发,按照节点不同能耗状态,由处理器模块控制节点各模块在不同工作状态间转换,使部分模块在节点工作的时间片内处于休眠的低功耗状态,最大程度降低节点能耗。Node power consumption is a key factor affecting the life cycle of wireless sensor networks （WSN）. Since in largescale farmland applications the continuous collection and uploading of the sensor data were not required, a node power consumption state machine was provided on the basis of the cluster head cycle-switching scheme. Considering the power consumption of a single node, function modules controlled by processor module converted among the different working conditions according to the different node energy states. Due to the low-power state of some modules, the node energy consumption can be minimized.
