Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to this Bright each embodiment is explained in detail.However, it will be understood by those skilled in the art that In each embodiment of the invention, in order that reader more fully understands the application and to propose many technologies thin Section.But, even if there is no these ins and outs and many variations based on following embodiment and modification, The each claim of the application technical scheme required for protection can also be realized.
The first embodiment of the present invention is related to a kind of dynamic switching method of communication frequency, in this embodiment party In formula, when self-organizing network nodes detect the switching for starting communication frequency when communication quality drops to certain thresholding Mechanism, notifies that peer node obtains the measurement time slot for measuring pilot frequency point of fixed interval, and in measurement In time slot, the pilot frequency point in alien frequencies point list is measured, to capture clean frequency as frequency The target frequency of switching, carries out the switching of communication frequency.Present embodiment is by taking unmanned plane and remote control as an example Illustrate, idiographic flow is as shown in Figure 1.
In a step 101, start shooting as the unmanned plane of self-organizing network nodes, the start process of unmanned plane with it is existing There is technology identical, will not be described here.
In a step 102, select initial frequency.Such as, unmanned plane arranges a frequency manually, makees It is the communication frequency between remote control, or, initial communication frequency is set in advance in unmanned plane, After start, unmanned plane gets the frequency automatically as the communication frequency between remote control.
Then, in step 103, the channel quality of unmanned machine testing present communications frequency.Specifically, As channel quality can pass through to receive the embodiment of the parameters such as the signal to noise ratio of signal, signal to noise ratio is bigger, illustrates letter Road quality is better, conversely, signal to noise ratio is less, illustrates that channel quality is poorer.Therefore, in this step, Unmanned plane can detect the channel quality of present communications frequency according to the signal to noise ratio for currently collecting.
Then, at step 104, whether unmanned plane judges the channel quality of present communications frequency less than the One pre-determined threshold.
Specifically, threshold T h1 of a signal to noise ratio can be set in unmanned plane in advance, each It is secondary collect signal to noise ratio after, the signal to noise ratio of collection is compared with threshold T h1, if less than should Threshold T h1, then illustrate that channel quality is poor, into step 105;If being not less than threshold T h1, Then illustrate that channel quality can meet communicating requirement, return to step 103, continue detection present communications frequency Channel quality.Wherein, threshold T h1 can be arranged according to emulation and empirical value.
When implementing, can be sentenced by a channel quality for realizing following logic is set up in unmanned plane Disconnected module, completes the execution of step 104:
Wherein, signal quality can be using parameters such as signal to noise ratios;Thresholding is arranged according to emulation and empirical value Th1。
Then, in step 105 with step 106, unmanned plane notifies that peer node (i.e. remote control) is obtained Take the measurement time slot for measuring pilot frequency point of fixed interval.
Specifically, in step 105, unmanned plane notifies the handover mechanism of remote control open communication frequency.
In step 106, unmanned plane distributes the measurement time slot for measuring pilot frequency point of fixed interval.Tool Say, unmanned plane self identification number and default random number generation function body, obtain the measurement of fixed interval Time slot.When implementing, randomized function F_RANDOM (x) can be write, the function is A random number from 0 to x is generated, using the ID of unmanned plane as randomization seed, that is, is passed through F_RANDOM (unmanned plane ID) generates the original position of measurement time slot to measure the cycle T modulus.Complete Into after the distribution of measurement time slot, the measurement time slot of distribution is notified to remote control, it is ensured that the section of communicating pair Point can get on all four measurement time slot, so as to avoid any one party from sending out in the measurement time slot of distribution The problem of the number of delivering letters.
Then, in step 107, unmanned plane is measured to pilot frequency point using the measurement time slot of distribution and is commented Estimate, obtain target frequency.Specifically, RSSI enters to be indicated to the signal intensity of the reception of each pilot frequency point Row measurement, if in the measurement time slot cannot in alien frequencies point list all pilot frequency points measurement, will The measurement of remaining pilot frequency point is continued to complete in next measurement time slot.Such as, in alien frequencies point list altogether There are 32 pilot frequency points, the measurement of 8 pilot frequency points can be completed in a measurement time slot, then will be by 4 Individual measurement time slot completes the measurement of all pilot frequency points in an alien frequencies point list.
In an alien frequencies point list is at least completed after the measurement of all pilot frequency points, by the RSSI for measuring Minimum pilot frequency point is used as target frequency.As RSSI is less, illustrate that the frequency is cleaner, i.e., at this Communicated on frequency, will be disturbed by less, therefore, the pilot frequency point conduct for selecting RSSI minimum The target frequency of frequency handover, can be effectively ensured the communication quality between unmanned plane and remote control.
Then, in step 108, the target frequency of acquisition is notified (i.e. distant to peer node by unmanned plane Control device).
Then, in step 109, unmanned plane will communicate frequency handover to target frequency with remote control. After step 109, return to step 103 continues the channel quality of detection present communications frequency.
It is seen that, in the present embodiment, when communication quality declines, cutting for communication frequency will be started The system of changing planes, according to the measurement result in the measurement time slot of distribution to each pilot frequency point, chooses frequency handover Target frequency, and will communication frequency handover to target frequency, MANET can be caused when being interfered, can With switching at runtime to clean frequency, it is ensured that the communication quality of MANET.And, realize simply, no Need to increase extra hardware spending.
It is additionally, since the change that the flight of unmanned plane can occur on room and time, and the frequency of initial communication Point is likely to be interfered during flight, and then has influence on communication quality.Therefore by by nothing The detection of the man-machine communication quality for carrying out frequency, and the handover mechanism of communication frequency is triggered, effectively can keep away Exempt to be forced the problem for re-starting that initial frequency search is arranged of making a return voyage because of the problem of communication quality.
