摘　　要：针对当前输电线路监测方法受到输电线路节点间多跳通信模式影响,无法实现输电线路精准监测的问题,设计了基于传感器技术的智能电网输电线路监测系统。采用远端监控装置,使实验导线两侧的受力平衡。使用SHTxx系列单片机的温湿度传感器,实现温度、湿度的监测。以MSP430F149单片机为核心,通过电力线载波传输相关信息。基于传感器技术对监测节点分组,计算各节点的自身权值。根据这一权值确定下一个节点为最大邻居节点,改进了簇间的多跳通信机制,以保证传输线信息全部传输到控制中心。根据监测流程,完成了输电线路监测。由实验结果可知,该系统监测温湿度分别存在0.05℃和0.05%的偏差,具有精准的监测效果。Aiming at the problem that the current transmission line monitoring methods are affected by the multi hop communication mode between transmission line nodes and can not achieve accurate transmission line monitoring,a smart grid transmission line monitoring system based on sensor technology is designed.The remote monitoring device is adopted to balance the stress on both sides of the test conductor.The temperature and humidity sensor of SHTxx series single chip microcomputer is used to realize the monitoring of temperature and humidity.MSP430F149 MCU is used as the core to transmit relevant information through power line carrier.The monitoring nodes are grouped based on sensor technology,and the weight of each node is calculated.According to this weight,the next node is determined as the largest neighbor node,and the multi hop communication mechanism between clusters is improved to ensure that all transmission line information is transmitted to the control center.According to the monitoring process,the transmission line monitoring is completed.The experimental results show that the temperature and humidity monitored by the system have deviations of 0.05℃and 0.05%respectively,which has accurate monitoring effect.
