The present invention provides a kind of signal calibration method and electronic equipment, is used to solve equipment distance reception in the prior art
The relatively low technical problem of the signal degree of accuracy.
In the prior art, surface-monitoring equipment can receive air traffic equipment and send out by radio-frequency channels such as antenna, cables
The signal for sending.When but ground installation receives signal by radio-frequency channel, because radio-frequency channel is in itself easily by the shadow of environment
Ring, such as temperature is too high in environment, temperature is too low, humid air is to noise in the corrosion of radio-frequency channel material or environment etc.
Transmission to signal exerts a certain influence, and the signal for causing ground installation to receive not is to control what transit equipment sent
, there is distorted signals phenomenon in actual signal, and the signal degree of accuracy for causing ground installation to receive is relatively low.
In order to solve the above problems, the technical scheme general thought in the embodiment of the present invention is as follows：

Art problem.
In order to be better understood from above-mentioned technical proposal, below by accompanying drawing and specific embodiment to technical solution of the present invention
It is described in detail, it should be understood that the specific features in the embodiment of the present invention and embodiment are to technical solution of the present invention
Detailed description, rather than the restriction to technical solution of the present invention, in the case where not conflicting, the embodiment of the present invention and implementation
Technical characteristic in example can be mutually combined.
Refer to shown in Fig. 1, be a kind of flow chart of signal calibration method provided in an embodiment of the present invention, the method application
In an electronic equipment, from figure 1 it appears that methods described includes：
Step 101：Receive the first signal of the first electronic equipment transmission.
Step 102：Determine the characteristic parameter of first signal.
Step 103：Obtain calibration signal corresponding with the characteristic parameter；Wherein, different characteristic parameter correspondences is different
Calibration signal.
Step 104：First signal is calibrated by the calibration signal, obtains secondary signal.
Optionally, the first electronic equipment in step 101 can with air traffic equipment such as personal aircraft, helicopter etc.,
Corresponding, electronic equipment can be surface-monitoring equipment.Certain first electronic equipment is not limited to air traffic equipment, as long as the
By transmission signals such as wired mode such as antennas between one electronic equipment and electronic equipment.
It should be noted that above-mentioned signal is the reason for producing distorted signals phenomenon during being transmitted in radio-frequency channel
For general radio-frequency channel such as antenna etc. is formed by cable design, is easier to be influenceed by environment.The middle temperature of such as environment
Height, too low temperature, humid air, strong wind etc. are spent to noise in burn into weathering of radio-frequency channel material etc. or environment etc.
Transmission to signal also result in certain influence.Therefore the signal that electronic equipment is received not is that the first electronic equipment is initial
, easily there is the phenomenon of distorted signals in the real signal for sending.
Before step 101 is performed, may first determine whether to need the signal to receiving to calibrate.The first is true
Whether it can be that electronic equipment can be according to current environment parameter determination to determine to need the mode for calibrating the signal for receiving
Whether the signal for receiving is calibrated, because if weather influences smaller or antenna material newer, even if or
The the first electronic equipment sending signal for receiving be distortion also have no effect on work if, electronic equipment can select not dock
The signal of receipts is calibrated.
The mode for determining the need for for second calibrating the signal for receiving can be that staff is rule of thumb
It is determined that the signal for receiving with the presence or absence of serious distortion situation, if it is, staff can actively start it is right
The work that signal is calibrated.
Certainly, also other modes for determining the need for calibrating the signal for receiving, the present invention does not make to have
The restriction of body.
Then start to perform step 101, that is, receive the first signal of the first electronic equipment transmission.With the first electronic equipment with
By as a example by antenna transmission signal between electronic equipment, during signal is transmitted in antennas, it may appear that distorted signals shows
As, electronic equipment as receiving terminal when the signal that the first electronic equipment sends is received, meeting when being transmitted in antennas due to signal
Decay, the first signal that final electronic equipment gets not is the signal i.e. actual signal that the first electronic equipment initially sends.
Therefore the actual signal that the first signal and the first electronic equipment that the electronic equipment in step 101 is received are originally sent is that have one
Fixed error.Refer to shown in Fig. 2, Fig. 2 is the comparison diagram of actual signal and the first signal, in order to obtain the first electronic equipment
The actual signal of transmission to the first signal, it is necessary to calibrate.
After the first signal for receiving the transmission of the first electronic equipment, electronic equipment starts execution step 102 and determines
The characteristic parameter of the first signal.Although the first signal that electronic equipment gets not is the true letter that the first electronic equipment sends
Number, but after electronic equipment gets the first signal, the characteristic parameter of the first signal is can determine whether, for example determine that the first signal is table
Levy power and change over time situation, then characteristic parameter is exactly power, if it is determined that the first signal is standard amplitude with the time
Situation of change, then characteristic parameter is exactly amplitude.Certain different types of signal has different characterisitic parameters.
Then start to perform step 103, that is, obtain calibration signal corresponding with the characteristic parameter.The first of step 103
It can send the first reference signal corresponding with the characteristic parameter to the calibration source to plant implementation；Receive the school
The second reference signal corresponding with first reference signal that quasi- source sends；According to first reference signal and described second
Reference signal determines calibration signal corresponding with the characteristic parameter.
Optionally, in order to obtain the actual signal that the first electronic equipment sends, can be in the first electronic equipment and electricity
A calibration source is set up between sub- equipment, the calibration source can be a frequency source, or broad band source etc..Electronic equipment and
One electronic equipment is connected by the first radio-frequency channel, and electronic equipment is connected with calibration source by the second radio-frequency channel, wherein, it is described
First radio-frequency channel is identical or different with second radio-frequency channel.Refer to shown in Fig. 3, be that the first electronic equipment, electronics set
Signal transmission figure between standby and calibration source, can be specifically that electronic equipment receives described by first radio-frequency channel
The first signal that first electronic equipment sends；And sent and feature ginseng to the calibration source by second radio-frequency channel
Corresponding first reference signal of number；Then joining with described first for the calibration source transmission is received by first radio-frequency channel
Examine corresponding second reference signal of signal.
When the first radio-frequency channel is different with the second radio-frequency channel, the first is according to the first reference signal and second with reference to letter
Number being determined at the mode of the corresponding calibration signal of characteristic parameter can be, electronic equipment is sent out by the second radio-frequency channel to calibration source
Send after the first reference signal corresponding with characteristic parameter, the first reference signal does not decay in the second radio-frequency channel, that
The first reference signal that calibration source is obtained be not through overdamping, then calibration source will first reference signal send and
First radio-frequency channel so that the first reference signal is transferred to electronic equipment by the first radio-frequency channel.So electronic equipment is obtained
The second reference signal be exactly the first reference signal only by the first radio-frequency channel decay after signal.Then described is obtained
First difference of one reference signal and second reference signal, first difference is calibration corresponding with the characteristic parameter
Signal.
Optionally, penetrated with first, it is necessary to the first reference signal is sent after calibration source gets the first reference signal
Frequency passage, its implementation can send corresponding with characteristic parameter to calibration source by the second radio-frequency channel in electronic equipment
The first reference signal while, can carry a control instruction in the first reference signal, the control instruction is used to control school
Quasi- source sends and the first radio-frequency channel the first reference signal so that the first reference signal is sent in the first radio frequency and led to by calibration source
Road, like this, electronic equipment can receive the corresponding with the first reference signal of calibration source transmission by the first radio-frequency channel
Second reference signal, then the second reference signal is signal of first reference signal after decay in the first radio-frequency channel, with
The actual signal that first electronic equipment is originally sent have passed through identical attenuation degree in the first radio-frequency channel.
The corresponding calibration signal of characteristic parameter is determined at according to the first reference signal and the second reference signal for the first
Mode for, it is necessary to carry out special treatment to the second radio-frequency channel so that the first reference signal is in the second radio-frequency channel
Do not decay during transmission.Concrete implementation mode can be that electronic equipment is first led to the first reference signal by analog signal
Cross digital modulation and demodulation algorithm and be changed into corresponding data signal, then by the data signal by the second radio-frequency channel send with
Calibration source, then the digital signal transition is being analog signal by calibration source.This is done because data signal is in transmitting procedure
In will not decay.The benefit for taking this mode is that the calibration signal for obtaining is more accurate.
When the first radio-frequency channel is different with the second radio-frequency channel, second according to the first reference signal and second with reference to letter
Number being determined at the mode of the corresponding calibration signal of characteristic parameter can be, electronic equipment is sent out by the second radio-frequency channel to calibration source
Send after the first reference signal corresponding with characteristic parameter, the first reference signal occurs to decay and decays in the second radio-frequency channel
Predetermined value, then what calibration source was obtained is the first reference signal through the signal after predetermined value described in overdamping, then calibration source
Signal after the predetermined value that decays is sent to the first radio-frequency channel, then electronic equipment is transferred to by the first radio-frequency channel.
In this case, electronic equipment obtains the second reference signal and have passed through and decay twice, then obtain second reference signal with
Second difference of first reference signal；And obtain the first He of the second difference and the predetermined value, described first and be with
The corresponding calibration signal of the characteristic parameter.
The corresponding school of characteristic parameter is determined at according to the first reference signal and the second reference signal for above-mentioned second
, it is necessary to the predetermined value decayed when knowing that signal is transmitted in the second radio-frequency channel for the mode of calibration signal, for example can be with
Value for obtaining etc. is tested by many experiments.The benefit adopted in this way is, it is not necessary to which it is special that the second radio-frequency channel is carried out
Treatment, it is relatively more cost-effective.
When the first radio-frequency channel is identical with the second radio-frequency channel, determined according to the first reference signal and the second reference signal
Can be that the first reference signal is logical by the first radio-frequency channel and the second radio frequency in the mode of the corresponding calibration signal of characteristic parameter
Road have sent the decay that there occurs same degree twice, then the first reference signal is exactly first with the difference of the second reference signal
Signal is 2 times of attenuation degree in the first radio-frequency channel, then obtain the difference between the first reference signal and the second reference signal
/ 2nd of value are exactly calibration signal corresponding with the characteristic parameter.
Benefit using above-mentioned first radio-frequency channel and the second radio-frequency channel identical mode is, cost is relatively low and practicality
By force.
Above-mentioned the first implementation for teaching step 103, then second implementation of step 103 can be,
The corresponding relation of characteristic parameter and calibration signal is prestored in the electronic device, specifically, what is prestored is which characteristic parameter can
Depending on according to actual conditions, the different parameter such as such as characteristic parameter can be, phase, amplitude, power.Certainly, in electronics
Before equipment obtains the corresponding relation of storage characteristic parameter and calibration signal, it is necessary first to obtain characteristic parameter right with calibration signal
Should be related to.It is succinct for specification and the mode that obtains corresponding with characteristic parameter calibration signal is similar with foregoing mode,
Therefore not to repeat here.
Optionally, it is have characteristic parameter and school in electronic equipment using the benefit of second implementation of step 103
If the corresponding relation of calibration signal, when electronic equipment receives the first signal, calibration can be directly determined from corresponding relation
Signal.First signal of such as acquisition is that amplitude changes with time relation, then can be determined at by searching corresponding relation
The corresponding calibration signal of amplitude, refer to shown in Fig. 4, be the corresponding relation of amplitude and calibration signal.Take the good of this mode
Place is can to improve the efficiency of signal calibration.Likewise, electronic equipment can also obtain the corresponding school of the parameters such as power, phase
Calibration signal, then stores compared with calibration signal.Fig. 4 is to list the situation that characteristic parameter is amplitude, naturally it is also possible to be other
Characteristic parameter.
Certainly, if it is determined that after the characteristic parameter of the first signal, characteristic parameter and the school for prestoring in the electronic device are found
Described in the corresponding relation of calibration signal during characteristic parameter, electronic equipment can be using the first implementation of step 103.
Optionally, features described above parameter can periodically update with the corresponding relation of calibration signal, and reason is：Electronics sets
Standby is affected by environment with the radio-frequency channel between the first electronic equipment, and environment changes over time, different rings
Under border, the first radio-frequency channel is different to the attenuation degree of signal.Therefore, electronic equipment needs periodically to update this feature parameter
Corresponding relation between calibration signal, the specific cycle be how long, internet can be combined obtain environment and change with time feelings
Condition, it is also possible to which the factor such as degree of aging of experience combination radio-frequency channel material according to staff determines.
Optionally, after execution of step 103, step 104 can be performed, i.e., the first signal is carried out by calibration signal
Calibration obtains secondary signal.
For example, if the characteristic parameter of the first signal is amplitude, then determine in step 103 corresponding with amplitude
Calibration signal after, the first signal can be calibrated by calibration signal, will the first signal and calibration signal carry out
Superposition, then obtains secondary signal.By the secondary signal obtained after calibration, what is be just originally sent with the first electronic equipment is true
