Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
In order to illustrate technical solutions according to the invention, the following is a description of specific embodiments.
Fig. 1 shows the process of short wave network Situation Awareness implementation method provided in an embodiment of the present invention, and Fig. 2 is shortwave net
Network Situation Awareness realizes the frame structure of system, and only parts related to embodiments of the present invention are shown for ease of description.
In conjunction with shown in Fig. 1,2, present invention method includes the following steps:
Step S1, collection, storage and network insertion node and the location information of user are managed, the location information comes from
Acquisition is transmitted in GIS-Geographic Information System or by the short wave channel in shortwave isomerization access network.
In short wave network, the GIS-Geographic Information System can be dipper system or other positioning systems, be distributed in short
The location information of each access node and user in wave isomerization access network can be obtained by GIS-Geographic Information System.For position
Confidence breath also can use reporting position function of the user after link setup success in shortwave isomerization access network and pass through short wave channel
Transmission obtains customer position information.
Step S2, the network resource information from each network management system of shortwave isomerization access network is collected.
The network management system is each network management system of shortwave isomerization access network interconnected, and the Internet resources of collection are believed
Breath includes essential information, idle state and the ability of user and state etc. of the transceiver equipment of each node.
Step S3, the detection data for receiving timing or being collected on demand, by predicting and combining access node and use
The location information at family forms each node and the usable frequency window of user.
The detection data includes the real-time detection data of detection network, monitoring net and the quick link setup system output of shortwave, than
The noise data of the detection data, monitoring net output that are exported such as detection network, wherein the detection data of detection network output is outer
Chirp detection result, Modem detection result, survey grid data of hanging down for connecing etc., the noise data are that monitoring net monitors station noise
Monitoring result.Quick link setup system is that have the link setup system of broadband reception, fast signal detection and frequency spectrum perception ability, can be used
In quick and live signal quality detection, detection data can be received using quick link setup system on demand.
When specific implementation, this step needs to be divided into two kinds of situations:
(1) when exterior access has the forecast information of sunspot number, that is, there is the forecast information of sunspot number defeated
Fashionable, according to sunspot number combining position information, sunspot number used in real-time update Long-term prediction model leads to simultaneously
High Availabitity frequency MUF and lowest usable frequency LUF that sunspot number combination Long-term prediction model acquires any link are crossed, it is described
The usable frequency window of MUF and LUF composition node and user.
According to ionospheric propagation theory, not all shortwave can be from ionospheric reflection fold-back ground.Upper frequency
Shortwave could reflect fold-back ground from the ionosphere being distributed compared with high electron density.Ionization for certain electron density distribution
Layer and certain sending and receiving distance, the electric wave that can reflect fold-back ground have a maximum frequency, referred to as maximum usable frequency MUF,
It is lower with the reduction of distance between transmitting-receiving.Therefore, sending and receiving can reflect the highest of the electric wave on fold-back ground in same point
Frequency is minimum in MUF corresponding to the ionosphere of this electron density distribution, referred to as ionospheric critical frequency.If receive,
Distance is certain between hair, and tranmitting frequency is lower, and receiving point can receive the high and low angle wave of certain delay inequality；As frequency is got higher,
Angle of site wave delay inequality reduces so that gradual change is to zero, and angle of site wave is overlapped；If frequency increases again, receiving point fall into jump away from
It is interior, it can not receive transmitting signal completely.Therefore, the frequency that the circuit of certain distance can be propagated must have a upper limit, frequency limit on this
Rate is known as the maximum usable frequency of the circuit.In addition, energy of the electric wave through ionospheric propagation can also be ionized layer absorption, absorb big
It is small to be usually inversely proportional with frequency square.Frequency is lower, then reduces due to signal level increases because absorbing.Can just it expire when level is reduced to
When the minimum received signal to noise ratio of foot requires, frequency used is known as the lowest usable frequency LUF of the circuit.It can be seen that shortwave passes
Broadcasting should be as far as possible with high frequency to reduce absorption.
Long-term prediction model be shortwave propagated in ionosphere a model description, and sunspot number influence whether it is short
Wave transmission, therefore sunspot number is also a parameter of model, therefore when external access has the forecast information of sunspot number
When, it first has to carry out parameter setting and amendment to model according to sunspot number.In this step, each access node is also combined
With the location information of user, and network resource information has reacted access node and the use state of user, can be obtained so each
The usable frequency window of a idle node and user.
(2) when outside is without access sunspot number forecast information, i.e., when no sunspot number forecast information inputs,
Only detection network, monitoring net and shortwave quick link setup system output real-time detection data, using pseudo- sunspot number method of prediction,
By the maximum usable frequency MUF at one or more detecting link moment, the pseudo- sunspot number PSSN at the moment is calculated,
After obtaining pseudo- sunspot number, sunspot number used in real-time update Long-term prediction model passes through pseudo- sunspot number knot
Close MUF and LUF that Long-term prediction model acquires any link.The quick link setup system of the shortwave of system configuration can be in real time and on-demand
Update detection data.
Step S4, according to the usable frequency window and disabling frequency is combined to obtain available frequency range, is then based on institute
It states detection data and forms Link Channel Quality, collectively form the usable frequency of shortwave isomerization access network each access node and user
Range and channel quality, then extrapolated by space-time two-dimension, and combine historical frequency, synthesis forms shortwave isomerization access network and respectively saves
The frequency spectrum covering situation and user's frequency spectrum of point cover situation.
This step is realized through detection data, and disabling frequency and historical frequency is combined to realize frequency spectrum covering situation and use
Family frequency spectrum covers situation.When specific implementation, include the following steps:
Disabling frequency information is obtained in S41, net frequency management system of joining the army first, then from access node and user can
With the disabling frequency and the big frequency of interference is rejected in frequency window, formed in the following certain time of access node and user
Available frequency range.
Can be acquired in army's net frequency management system in 5000 kilometer range of typing territory and periphery shortwave disabling frequency and
Frequency is protected, these frequencies belong to military frequency range, and other party cannot use.Therefore the usable frequency window in node and user is needed
It is middle to reject the disabling frequency and some big frequencies of interference, obtain available frequency range.
S42, link detection data are formed by the detection data for collecting the quick link setup system of detection network, monitoring net, shortwave,
Obtain Link Channel Quality.
It is supervised by real-time detection (such as external Chirp detection result, Modem detection result, survey grid data of hanging down) with noise
It surveys (monitoring station noise monitoring result) and obtains Link Channel Quality.In addition, there is pectrum noise perception and fast by what is developed
The quick link setup system of the shortwave of fast signal detection carries out channel quality detection and noise perception, obtains link channel matter in real time
Amount.
For the channel quality forecast of known users, real time channel quality is obtained by instant detection data, and pass through reality
When modified result long-term forecasting, predict a period of time in channel quality.For the channel quality forecast of unspecified persons, pass through
The interference of frequency spectrum perception data acquisition region, and by interpolation calculation channel energy, the frequency coverage quality in region is obtained (in region
The frequency quality data of each subdivided meshes).
The step of calculating each access node each frequency coverage quality condition as shown in figure 4, wherein propagation loss use
Long-term forecasting, the area of coverage calculate the combined influence for considering earthwave, D layers, E layers, F layers sky wave
1) the whole network support area is divided into zonule one by one by certain particle size (region of longitude and latitude respectively once)；
2) to each cell, access node is calculated to the propagation loss of cell, obtains signal energy；
3) ambient noise is obtained according to frequency spectrum perception data, calculates signal-to-noise ratio as cell signal-to-noise ratio；
4) compare cell signal-to-noise ratio and thresholding, if more than thresholding, then the cell is capped, is otherwise uncovered；
5) repeat 2), 3), 4) step, calculate the coverage condition of all zonules, obtain the coverage condition of access node.
S43, spatially, in the available frequency range of formation, using spatial extrapolation method, based on several chains road known
The channel quality data detected, using the relationship of space length and channel quality data, interpolation is obtained to other in network
The channel quality data of link is extrapolated.
S44, on the time, the neural network model of long-term forecasting is established, neural network model first carries out initialization training,
Then amendment of the training realization in real time to neural network model is carried out using detection data and historical frequency data, utilizes amendment
Long-term prediction model afterwards calculates the coverage condition of the following a period of time usable frequency of access node and user.
Space-time two-dimension Extrapolation method of the embodiment of the present invention based on link measured data obtains certain time and spatial dimension
The frequency spectrum situation of interior available frequency range.On time dimension, long-term forecasting mould is corrected by real-time detection data and historical data
Type improves forecast precision and time domain validity.On Spatial Dimension, use space extrapolation expands the effective region model of detection data
It encloses, avoiding detection data from being unable to coverage region causes computational accuracy to decline.Here historical frequency data represent certain frequency
The communication quality of certain chain road, can be converted into local overlay area analysis as a result, for Data Fusion, can also
With can understanding and considerate condition for analyze each channel of access node.
S45, it is postponed outside by space-time two-dimension, finally obtains each access node and the frequency situation information of user.The frequency
Rate situation information include node and user (or node is to certain area) current and future for a period of time in usable frequency and right
The frequency quality answered.
The main feature of frequency situation generation method of the invention has:
1, it crosses number of ways and collects frequency spectrum situation in real time.Including real-time frequency detection (Chirp detection result, Modem detection
As a result, vertical survey grid data), obtain live signal energy intensity and available frequency range.The free device in each region is to this
The frequency interferences in region are monitored scanning, obtain local interference profile.In addition, the quick link setup system of shortwave can on demand at any time
Obtain signal energy intensity and available frequency range and interference profile.Also usage history frequency is directed to currently used link,
The frequency usage qualitative data of user is collected, statistical history can the accumulation of passband rate.
2, expand the effective territorial scope of detection data using two-dimentional extrapolation, detection data is avoided to be unable to coverage region
Computational accuracy is caused to decline.
3, by real-time detection data correction Long-term prediction model, forecast precision and time domain validity are improved.
4, usage history frequency data optimization assignment result.
The present invention overcomes legacy frequencies management systems, and long-term forecasting and single-mode chirp only to be relied on to detect as frequency
The deficiency of selection and assignment foundation.Meanwhile conventional detection and monitoring network deployment place are limited with range, detectivity and monitoring
Ability is limited, and the quick link setup system customer equipment of shortwave can arbitrarily move and have full frequency band detection and sensing capability, can be real-time
Feedback frequency quality information, and dispose according to demand at an arbitrary position, to improve the real-time of channel quality acquisition and improve ground
Domain covering precision.
For spatial extrapolation method, i.e. above-mentioned steps S43, extrapolated by interpolation method.For no real-time detection number
Predicted value is obtained using spatial extrapolation algorithm according to the region or link for using data.By the forecast data and reality of surveying link
Border detection data, and neighbouring link forecast data in the same direction carry out etc. that the effective energy of the link can be predicted than calculating:
L=a1(L"/L"c)*Lc+a2
Wherein L is prediction link load, LcFor long-term forecasting computed losses, L ", L "cIt is divided into the active loss of known link
It is lost with forecast, a1,a2For calculation constant.
For the distribution link within the scope of 1000km, the theoretical error of this prediction technique is generally within 2dB, in engineering
On be acceptable.Fig. 3 is signal energy of the known Nanjing to Guangzhou, Changsha, and extrapolation obtains all cells within the scope of territory
Domain to access node signal energy theoretical error simulation result.
For full frequency band situation data, since the data effective range of general actual node is limited, so often having very
Shortage of data mostly geographically, the effective range of general link can only cover nearby 100 kilometers or so of transmitting-receiving point.The present invention uses
Spatial extrapolation algorithm calculates the frequency spectrum situation of adjacent territories by effective physical link data, and perceptually data are added
Into frequency spectrum situation, the decline of computational accuracy caused by lacking due to area data is effectively reduced, the effective region of detection data is extended
Coverage area.Meanwhile by disposing the quick link setup system of shortwave, it can detect on demand whenever and wherever possible, form the letter in specified range
Road quality information can be further improved the precision of prediction in coverage area.
Generally rule of thumb formula is calculated existing frequency predication algorithm, due to the continually changing influence in ionosphere, and
The mean value Comparative result that empirical equation obtains, often calculating error can be larger.For long-term forecasting algorithm for real-time prediction
The inadequate problem of precision, the present invention is extrapolated by the time and introduces detection data and historical data, corrected using neural network, right
Current long-term prediction model is modified, and Long-term prediction model is enabled to be more in line with current Ionospheric variability rule, can be with
Effectively improve the precision of forecast calculation.The modified realization of neural network utilizes real-time frequency using long-term forecasting as basic model
