An automatic radio monitoring and early warning architecture based on C/S for illegal broadcasting

Current radio spectrum monitoring systems are “man-machine” communication systems based on Radio Monitoring Transfer Protocol (RMTP), which are unable to detect and process the radio interference automatically. In this paper an automatic radio monitoring and early warning architecture based on C/S model and internet protocol is proposed. A pilot “machine-machine” system which consists of several sensor nodes and an application & service (A&S) center for monitoring and early warning to illegal broadcasting is implemented using Baidu map JavaScript API technology and Windows Presentation Foundation (WPF). The sensor node is a RTL-SDR connected to an industrial computer. It mainly takes charge of illegal signal detection, early warning and monitoring data storing. What's more it provides a web service for the A&S center to retrieve the monitoring data in a fixed time interval for further data presentation and statistical analysis.
