摘  要:
针对复杂农田环境对无线信号干扰强、节点能耗大等问题,设计一种改进的农田信息采集无线传感器网络节点。该节点以单片机为核心控制器,优化无线传感器节点任务调度,并且提出"模拟化+路径"的方法结合滑动平均数字滤波技术对数据采集和处理。实验表明:该无线网络节点增加了能源的利用率,提高数据采集的精度(精度达到97.6%),可以满足农田信息采集的应用要求。

摘  要:
Modified wireless sensor network node for field information acquisition was provided,in order to solve the problems existed in complicate field environment such as strong wireless signal interference,high node energy consumption etc.MCU was made as core controller of wireless sensor nodes to promote the task scheduling.The data was acquired by the method had been proposed which combines simulation and path,and then the data was processed with moving average digital filtering technology.The results showed that the energy use ratio was increased and the data acquisition accuracy was promoted to 97.6% with the wireless network node,which could meet the requirements of field information acquisition.
