无线传感节点节能措施的研究

The study of the energy saving measure in wireless sensor nodes

在传统的无线传感网络节能措施的基础上,在项目实施过程中,引入了智能电池管理系统,并在其中实现动态电源管理,对整个传感节点的能量进行有效合理的安排。动态电源管理通过对系统的时钟或电压的动态控制,并设置微处理器的寄存器,有选择地关闭不需要的功能模块,以达到节电的目的。同时动态的关闭一些仍然需要的外设控制器来进一步节省能量。并进一步采用均衡能量的方法来延长单个节点的使用寿命,获得更长时间跨度内的有效数据。

Based of the conventional energy saving method used in the wireless sensor network,we consider the technology of intelligent power management in the project,and we realized the dynamic power management which can manage the energy in effective ways.The dynamic power management economized the energy by controlling the system RTC or voltage, setting the register of the MCU and closing the module which is free.Further more,we can also close some exterior controller to save energy.By the same time,we adopt the technology of energy equilibrium to extend the using time of the node.
