摘    要:针对无线传感器网络节点能量受限制问题,提出一种节能网络,把监测环境中通电电缆的磁能转化为电能,实现节点能量的自给。采集的能量采用双边调谐阻抗网络传输,通过设计原副边回路参数,令其回路发生谐振来降低自身损耗;组网模式上,用节能静态网络模型代替能耗大的动态组网方式,结合需要,通过切换节点的工作方式来降低能耗。实验证明,能量采集模块一个工作周期采集的能量为10.93 mJ,能够满足传感网络节点工作周期的最大能耗4.68 mJ,验证了节能传感网络可以实现能量自給。

关 键 词:无线传感器网络  双边调谐  节点工作方式  自给

Abstract:Aiming at the energy limitation of wireless sensor network node, an energy-saving network is proposed, which can transform the magnetic field energy of laying wire cables in monitoring environment into electricity power, to ensure energy can be self-sufficient. The collected energy is transmitted by double-tuned impedance network. By designing the loop parameters, the loop is resonated to reduce its own loss. In the networking mode, the energy-saving static network model is adopted instead of the dynamic network model with large consumption. It can also reduce energy consumption by switching working mode of node. The experimental results show that the energy collected by energy harvesting module is 10.93 mJ, which can meet the maximal energy consumption of 4.68 mJ in sensor nodes. It is proved that the energy-saving sensor network can realize self-sufficiency.
