Abstract
The utility model relates to a mobile multi-channel electromagnetic radiating monitoring system. The system comprises an antenna device and a monitoring mainframe. The antenna device is connected to the monitoring mainframe transmitting the electromagnetic signal to the monitoring mainframe; after the monitoring mainframe processes the amplifying, filtering, and module converting for the electromagnetic signals, the mainframe memorizes the testing data reflecting the coal rock power disaster, being characterized in that the antenna device is composed of the directional wide frequency antenna without interference. The utility model uses the unidirectional multi-width frequency antenna to receive the signals and transmits the synchronous data to the monitor. The advantage of using the antenna is the signal receiving without interference, at the same time the large range monitoring reduces the measuring time and enhances the coal output.
