摘　　要：针对频谱监测设备低成本、小型化的需求,提出了一种基于无线传感器网络的频谱监测方案.该方案利用频谱接收模块采集空间FM(frequency modulation,调频)信号;使用控制器模块对数据进行处理,并通过无线传感器网络的方式实现节点间的组网通信,完成数据的无线传输;采用斐波那契优化算法处理节点采集的数据.测试结果表明基于该小型化的无线电频谱监测节点可实现网络化的对FM信号的采集和无线传输,使用的算法能准确地提取有效信号.This research highlights a proposed spectrum-monitoring scheme focused on achieving a low-cost and miniaturized spectrum-monitoring equipment. The scheme utilizes the spectrum-receiving module to collect spatial frequency modulation(FM) signal. The controller module is used to process the data,and the network communication between the nodes is realized through the wireless sensor networks to complete the wireless transmission of the data. The Fibonacci optimization algorithm is used to process the data collected by the nodes. The test results show the mini-based wireless spectrum-monitoring node can achieve the acquisition and wireless transmission of FM signals by the network,and the algorithm can accurately extract effective signals.
