Brief description of the drawings
Attached drawing herein is merged in specification and forms the part of this specification, shows the implementation for meeting the present invention
Example, and for explaining the principle of the present invention together with specification.
Fig. 1 is earth station and link ground device systems Topology connection schematic diagram.
Fig. 2 is spectrum signal ability figure.
Embodiment
To make the purpose, technical scheme and advantage that the present invention is implemented clearer, below in conjunction with the embodiment of the present invention
Attached drawing, the technical solution in the embodiment of the present invention is further described in more detail.
Unmanned aerial vehicle station in the present invention is connected with the system topological of link ground equipment as shown in Figure 1, frequency spectrograph 2 is right
Link ground equipment 3 carries out receives frequency signal acquisition, and earth station 1 controls frequency spectrograph 2 to gather center frequency by serial ports/Ethernet
The spectrum information collected is transferred to earth station 1 by the spectrum informations such as rate, bandwidth, datum, frequency spectrograph 2.Earth station 1 passes through
Raw spectroscopy data processing and analysis of the application software to collecting.
If what link ground equipment frequency of use was fixed is divided into multiple continuous working channels, user is by switching frequency
Road adjusts antenna efficiency frequency spectrum.When earth station's application software carries out spectrum monitoring, following manner is taken：
1) 1 remote control frequency spectrograph 2 of earth station needs to cover with certain wide spectrum (such as 200MHz) signal scanning, surface sweeping process
Antenna efficiency frequency；
2) the acquired original spectral signal energy data that frequency spectrograph 2 sends will be received and carries out graphic plotting, and in figure
Bottom marks out working channel, and member easy to operation judges which channel has interference, which channel does not interfere with；
3) original signal spectrum signal energy will be received each working channel energy is carried out according to working channel and be averaged, and by energy
The working channel of average minimum is optimal channel and is recommended operator, and member easy to operation is judging work at present channel letter
Make an uproar than it is abnormal when, switch to optimal channel.
Frequency spectrograph collection as shown in Figure 2 and the spectral signal energy figure drawn, fixation is taken in each working channel
On the basis of bandwidth, 5 channels are split into, it is named as 4 grades of channel 1, channel 2, channel 3, channel channels 5 successively,
Each channel has sampled 100 frequency points, then the reception energy that 100 frequency points have been carried out to it is averaged.From the figure, it can be seen that frequency
Figure fluctuation is the gentlest in road 5, it was demonstrated that this channel interference is few, if occurring in link ground equipment and unmanned plane communication process
Signal interference, then switch to rapidly channel 5 and continue to be controlled unmanned plane.
In above process, if link frequency of use needs earth station operator directly to set working frequency, by ground
After the operator that stands directly inputs centre frequency, bandwidth, datum, remote control frequency spectrograph carries out spectrum signal acquisition, ground
The acquired original spectral signal energy data that the frequency spectrograph received is sent directly are carried out graphic plotting by application software of standing.
The present invention the communication channel system of selection of unmanned aerial vehicle station by the frequency spectrograph remote interface terminal of earth station come
Link ground based terminal frequency spectrum initial data is gathered, and data analysis, display are carried out by application software, improves Unmanned Aerial Vehicle Data
The management of chain working frequency and fault location investigation efficiency, reduce support personnel, simplify control behaviour of the user for frequency spectrograph
Make.
The above, is only the optimal embodiment of the present invention, but protection scope of the present invention is not limited thereto,
Any one skilled in the art the invention discloses technical scope in, the change or replacement that can readily occur in,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with the protection model of the claim
Subject to enclosing.
