摘要
电源问题是无线网络传感器中的关键问题。只有提供长期有效的能源才能使网络传感器降低维护运行成本,进一步体现其巨大优势。本文首先以机械振动和光能收集的两种具体方法为例,对无线传感器的能量收集进行介绍;在能量管理中引进先进的电源动态管理技术,对能量实现有效利用,对储存元件-电池储存能量关键技术进行研究;最后对降低电能消耗的几种途径进行探讨。本文对无线网络传感器的能源设计具有重要的理论和应用意义。
Energy is the critical component of the wireless sensor networks. Only to provide efficiency and long using time energy, the wireless sensor networks could run in low cost to embody its advantage and be widely used. The paper introduces two way of energy harvesting by the mechanical vibration sources and solar energy to scavenge energy, introduces dynamic power management and battery storage to manage the power and discuss the methods of saving power. The paper has important significance to the energy theory design and application of the wireless sensor networks.
