摘要
在粮仓无线测量系统的设计中,测量节点由电池供电,它的低功耗设计是系统能否实用的关健技术之一。首先简单介绍节点的主要器件和工作流程,然后根据器件本身节能模式的特点,针对粮仓的实际应用要求,提出测量节点基于睡眠/唤醒的低功耗软硬件方案。经过实践证明,该方案能极大地降低节点日常工作能耗,延长节点生存周期。
In designing the Granary wireless measurement system, low power design of the battery-powered measure-nodes is one of the key technologies of whether or not the system is feasible. In this paper it firstly introduces main device and workflow of the nodes in brief, and then according to the characters of devices＇ power saving mode, a low power hardware-software scheme for measure nodes based on sleep/wake mode is designed in light of the practical usage requirements of the granary. It is proved by the experiment that the method the paper refers to is able to dramatically lower routine power consumption of the nodes, prolong the existence cycle.
