By building distributed spectrum detection nodes, collaborative detection of electromagnetic spectrum is realized. The efficiency and reliability of spectrum detection are improved, and the acquisition and processing of signal source data is realized in a more cost-effective electromagnetic spectrum detection system. Aiming at the problem of signal source data storage and visual analysis, this paper proposes a distributed electromagnetic spectrum database design in the electromagnetic spectrum detection node based on embedded system. After the signal source parameters are estimated in the cooperative detection, the data is packaged and sent to other detection nodes through multicast. Through the distributed database consistency protocol, the data consistency and data sharing of the spectrum database are realized. On the web side, access the spectrum database through the interface and read the data for visual analysis to form a two-dimensional spectrum map.
