And Performance

Currently, the electromagnetic environment has become more and more complicated. So, the research of real-time monitoring and analysis of regional radio signals and real-time display the electromagnetic situation of the region is more and more important. In this paper, the related technologies of the spectrum of existing monitoring systems is in-depth studied, and its own characteristics is analyzed, and on this basis, the reasons of using a distributed spectrum monitoring system is discussed. Secondly, for the demand of the issue, this paper put forward a design concept of distributed spectrum monitoring system which based on middleware, in other words, to apply the middleware technology to the distributed spectrum monitoring system, using the middleware to achieve the distribution of tasks and transmission of the results when coping with multiple testing tasks. Finally, designed and implemented the middleware, and the reliability and performance of middleware have been tested.

Aerial Vehicle

In this paper, we design and make a prototype of an aerial spectrum monitoring system that consists of a ground control station and a four-rotor unmanned aerial vehicle (UAV). This UAV carries a software-defined radio (SDR) receiver to perform spectrum monitoring tasks, including signal strength, frequency occupancy, and signal analysis. A light and low-cost SDR-based dongle consisting of RTL2832U chip and R820T tuner is employed as the monitoring receiver. A global positioning system and an electronic compass system are built on board to report the UAV’s position and direction. The open-source development platform GNU Radio is employed to design the radio monitoring system through the use of software-defined blocks. The proposed aerial monitoring system can detect radio signals in the frequency range of 25–1700 MHz that in practice covers the FM and DVB bands. With the prototype monitoring system, we have performed a few measurement tasks, including signal strength, waterfall display, and demodulation for identifying FM stations. Our proposed aerial monitoring system is more cost-effective than land-vehicle monitoring stations because of its much more flexible implementation.

Human Desire

Along with the times, recently there have been found tool to facilitate human’s work. Electronics is one of technology to facilitate human’s work. One of human desire is being safe, so that people think to make a tool which can monitor the surrounding condition without being monitored with people’s own eyes. Public awareness of the underground water channels currently felt still very little so frequent floods. To avoid the flood disaster monitoring needs to be done to underground water channels.This tool is controlled via a web browser. for the components used in this monitoring system is the Raspberry Pi technology where the system can take pictures in real time with the help of Logitech C170 webcam camera. web browser and Raspberry Pi make everyone can control the devices around with using smartphone, laptop, computer and ipad. This research is expected to be able to help the users in knowing the blockage on water flow and monitored around in realtime.
