Embodiment
The utility model embodiment is by providing a kind of monitoring radio-frequency spectrum device, solve in prior art, under the electromagnetic wave environment of complexity, cannot to the technical problem causing the radio of interference effectively to evade, and then achieve can effectively to the technique effect that the radio of interference is evaded.
In order to solve above-mentioned to the technical problem causing the radio of interference effectively to evade, cannot being described in detail technique scheme below in conjunction with Figure of description and concrete execution mode.
As shown in Figure 1, this monitoring radio-frequency spectrum device comprises: monitoring aerial 101, monitoring receiver 102, and arrangements for analyzing frequency 103.Wherein, between monitoring receiver 102 and frequency spectrum grading plant 103, also comprise data distribution device 104, the frequency spectrum data that this data distribution device 104 pairs of monitoring receivers 102 receive is shunted, thus obtains the preprocessed data corresponding to setting band limits; Signal amplifier 105 and traffic filter 106 is comprised successively between monitoring aerial 101 and monitoring receiver, wherein, the frequency spectrum data that signal amplifier 105 pairs of monitoring aerials 101 receive amplifies, and traffic filter 106 carries out filtering to the frequency spectrum data after amplifying, thus obtain the higher frequency spectrum data of signal to noise ratio.
The frequency spectrum data received is monitored frequency range in monitoring range according to parameter configuration by monitoring receiver 102 one by one, after a monitoring tasks carrying, carry out the monitoring of next task voluntarily, until selected task all terminates, after each monitoring task is complete, the analog signal of catching shows by monitoring receiver 102 in digital form, and signal is transmitted through the network to arrangements for analyzing frequency in digital form
