摘要：

为了实现输电线路监测的功耗低、寿命长、绿色发展的目的，提出大规模输电线路状态监测传感器网络周期性低功耗通信技术方案。依据网络中传感器网络组网特征以及节点运行状态转换特点，设置睡眠定时器，以周期性运行方式使传感器网络通信节点在初始化、睡眠、激活状态间转换，通信节点在输电线路状态监测数据无传递需求时进入睡眠状态，节省通信功耗；传感器网络汇聚（sink）节点利用梯度创建上行路由，通过源路由的方式创建下行路由，以跳数和剩余能量为依据进行上、下行路由数据分组传递，降低节点功耗，延长通信运行时间。实验显示，大规模输电线路状态监测传感器网络应用该技术方案后，通信功耗明显降低，运行时间明显延长，且不会影响监测传感器网络的数据传输性能，延长了监测传感器网络的使用寿命。

Abstract:

In order to realize the purpose of low energy consumption, long service life and green development of transmission line monitoring, a periodic low-power communication technology scheme of large-scale transmission line condition monitoring sensor network was proposed.According to the networking characteristics of sensor networks in large-scale transmission line condition monitoring networks and the characteristics of node operation condition conversion, sleep timers were set to make the communication nodes of sensor networks switch between initialization, sleep and activation states in a periodic operation mode.The communication nodes entered the sleep state when there was no transmission demand for transmission line condition monitoring data, so as to save communication energy consumption.Sink nodes in sensor networks used gradients to create uplink routes and source routes to create downlink routes.Based on the number of hops and residual energy, sink nodes transmitted uplink and downlink routing data packets, to reduce node energy consumption and prolong communication running time.Experiments show that after the large-scale transmission line condition monitoring sensor network applies the technical solution, the communication energy consumption is significantly reduced, the running time is significantly prolonged, and the data transmission performance of the monitoring sensor network is not affected, and the service life of the monitoring sensor network is prolonged.

Key words: condition-monitoring sensing network, low-power communication, sensor network node, routing node, periodic sleep, data packet
