Electromagnetic frequency spectrum monitoring system and method based on wireless sensor network

Abstract

The invention provides an electromagnetic frequency spectrum monitoring system and method based on the wireless sensor network, and aims at solving the problem of low accuracy in monitoring of the complex electromagnetic frequency spectrum space in the prior art. The electromagnetic frequency spectrum monitoring system comprises a frequency spectrum management center and N gateway centers in wireless connection, each gateway node is wirelessly connected with one sensing node at least, and each gateway / sensing node is integrated with a frequency spectrum monitoring module. The monitoring methodcomprises that the frequency spectrum management center issues a frequency spectrum monitoring task; each gateway node forwards the initial frequency and termination frequency; the frequency spectrummonitoring module integrated in the gateway node or the frequency spectrum monitoring module integrated in the sensing node connected to the gateway node obtains a frequency spectrum monitoring result and uploads the result; the gateway node forwards the frequency spectrum monitoring result to the frequency spectrum management center; and the frequency spectrum management center draws a frequencyspectrum graph. The frequency spectrum management center can draw the electromagnetic frequency spectrum monitored by the gateway node as well as the electromagnetic frequency spectrum monitored by the sensing node.
