摘要

为了有效延长节点工作寿命,设计一种新型的传感器网络节点能耗监测软件.传感器网络节点能耗监测系统的硬件主要由FPGA和控制板组成,所设计的软件将针对二者的工作流程进行控制.FPGA使用软件给出的采集程序和节点能耗识别码,进行传感器网络节点能耗数据的持续采集和模数转换.被转换成数字信号的节点能耗数据将被采集程序封装并传输到控制板.控制板根据数据读取流程对封装数据进行重构,获取完整的节点能耗数据并进行解析,给出节点能耗调节建议,实现对传感器网络节点能耗的监测.经实验验证可知,所设计的软件监测距离较远、传感节点工作寿命延长性能颇佳.%A new software for node energy consumption monitoring in sensor network was design for prolong the working life of the node. The hardware of the node energy consumption monitoring system for sensor network is mainly composed of FPGA and control board. The designed software controls the working process of both FPGA and control board. FPGA carries out continuous acquisition and analog-to-digital conversion of node energy consumption data in sensor network by means of the col-lection program and the node energy consumption identification code given by the software. The node energy consumption data converted into digital signal is packaged according to the collection procedures,and transferred to the control panel. The control panel is used to reconstruct the encapsulated data according to the data reading process to obtain and parse the complete node energy consumption data,and then give out some suggestions about node energy consumption adjustment to realize the monitor-ing of energy consumption of sensor network nodes. The experimental verification result shows that the designed software has re-mote monitoring distance,and can prolong the working life of sensor nodes.
