摘要
为了有效延长有毒有害气体无线监测节点的生命周期,提出了一种具有实用性的低功耗设计方案。该方案首先是对节点硬件实现分区分时的电源管理模式,其次在软件方面通过合理设置MCU的工作模式,通过实验方法确定了最优采样时间,进一步降低节点的功耗。
In order to effectively extend the life cycle of toxic and harmful gases wireless sensor network node,presented a practicality and low-power scheme.In this scheme, firstly,designed and achieved the partition time-sharing power management;Secondly,set the MCU work state rationally in software, and determined the optimal sampling time with experiment conclusion,further reduce the power consumption of the node.
