Specific embodiment
A kind of antenna positioning method, device and a kind of radio reception device are the embodiment of the invention provides, it is existing for solving
There is antenna to position the problem for being difficult to meet simultaneously and being accurately positioned and efficiently position.
To enable that goal of the invention of the invention, feature, advantage are more obvious and understandable, below in conjunction with the present invention
Accompanying drawing in embodiment, is clearly and completely described, it is clear that disclosed below to the technical scheme in the embodiment of the present invention
Embodiment be only a part of embodiment of the invention, and not all embodiment.Based on the embodiment in the present invention, this area
All other embodiment that those of ordinary skill is obtained under the premise of creative work is not made, belongs to protection of the present invention
Scope.
Fig. 1 is referred to, a kind of antenna positioning method one embodiment includes in the embodiment of the present invention：
101st, the target antenna is traveled through to preset the first step value according to default first path control targe antenna
Adjustable-angle；
In the present embodiment, when needing to carry out antenna positioning, can first according to default first path control targe antenna
To preset the adjustable-angle that the first step value travels through the target antenna.
It is understood that the antenna rotating path that above-mentioned first path can set, or calculate in real time
The antenna rotating path for obtaining.Assuming that the target antenna can both turn an angle in the horizontal direction, it is also possible to vertical
Turned an angle on direction, then the first path can be it is vertical after first level, or it is first vertical after horizontal mode carry out
Traversal.
Wherein, mode vertical after first level is traveled through and can be specifically：First control targe antenna is with the first step value
Horizontally rotate to stall position from initial position forward direction, then Vertical Square is rotated up an angle for step value, be further continued for anti-
To horizontally rotating to next stall position, subsequently vertical direction rotates an angle for step value, and then positive level turns
Move to next stall position ... until the target antenna has traveled through all adjustable-angles, then it represents that first path is walked
It is complete.
Similarly, first vertical rear horizontal mode is traveled through and can be specifically：First control targe antenna is with the first step value
Stall position vertically is turned to from initial position forward direction, an angle for step value is then rotated in horizontal direction, then reversely hang down
Next stall position is directly turned to, an angle for step value is subsequently rotated in horizontal direction, then positive vertical rotation
To next stall position ... until the target antenna has traveled through all adjustable-angles, then it represents that first path is walked
It is complete.
Especially, when the target antenna horizontal direction adjustable-angle is more than vertically adjustable section angle, described the
One path should select vertical mode after first level to be traveled through；Conversely, working as the vertically adjustable section angle of the target antenna
During more than horizontal direction adjustable-angle, the first path should select first vertical rear horizontal mode to be traveled through, so
The loss time that target antenna is traveled through is advantageously reduced, the location efficiency of target antenna is improved.
In the present embodiment, the first above-mentioned step value can preset.The rotation of first step value and target antenna
Angle is relevant with the stepper motor steps for driving target antenna to rotate.In addition, the anglec of rotation of the target antenna and stepping electricity
The step number transformational relation of machine can be by being calculated.For example, it is assumed that currently used stepper motor model is horizontal direction 64
Decay, 32 times of decay of vertical direction again, the rotation steps in current algorithm interface in units of angle, enclose by horizontal direction rotation 1
Required umber of pulse (i.e. step number) is 4096, and to ensure the accuracy of algorithm, selection can be converted to the angle of integer step number,
Angle can be then with the transformational relation of step number：Step number=angle * 4096/360.Vertical direction is similarly.
Furthermore it is preferred that for general antenna, its adjustable-angle is omnibearing angel to the maximum.Assuming that target
Antenna can both horizontally and vertically rotate, if the adjustable-angle of horizontal direction is 180 °, the adjustable angle of vertical direction
It is 360 ° to spend, then the adjustable-angle of its solid space is 180 ° * 360 °, you can reach the requirement of omnibearing angel.Similarly, hang down
Nogata to adjustable-angle be 180 °, the adjustable-angle of horizontal direction is 360 °, it is also possible to so that target antenna reaches entirely
Orientation angles it is adjustable.

As need to wait a time t on each aerial angle, wait when getting the signal intensity on the aerial angle, then go to down
One aerial angle.
103rd, the pre-conditioned corresponding aerial angle of the signal intensity will be met and is defined as first antenna angle, and in
The only traversal of the target antenna；
When the signal intensity that the target antenna is received on each aerial angle is got, will can meet default

Traversal.
It is understood that the present invention improves location efficiency to realize the quick positioning of antenna, can not require to find
To the best angle of target antenna, in ergodic process, as long as the signal intensity for getting meets pre-conditioned, then can be direct
Carry out it is follow-up it is thin select step, and stop current ergodic process, it is to avoid expend the excessive time in ergodic process.
Further, above-mentioned steps 103 can specifically include：It is default whether the signal intensity that detection gets exceedes
First threshold；If the signal intensity for getting exceedes default first threshold, stop the traversal of the target antenna,
And determine that more than the corresponding aerial angle of the signal intensity of the first threshold be first antenna angle；If until the mesh
Mark antenna completes the signal intensity for being still not detected by exceeding the first threshold during ergodic process, it is determined that in the target antenna
The aerial angle of the signal intensity maximum received in ergodic process is first antenna angle.
It is understood that when the signal intensity for getting is detected the presence of more than first threshold, then showing to search out
Meet desired aerial angle, now in order to improve location efficiency, the traversal of target antenna can be stopped, and determine that it is first
Aerial angle.If meeting desired aerial angle until traversal completes still to be not found, it is determined that the maximum antenna of signal intensity
Angle is first antenna angle.
104th, the zone signal intensities in each the first angle adjustable region are obtained；
It is determined that after the first antenna angle, the regional signal that can obtain each the first angle adjustable region is strong
Degree, the first angle adjustable region is the region corresponding to the antenna angle adjustable on the basis of the first antenna angle,
And the area size in the first angle adjustable region is default first area value.
It is understood that the first above-mentioned angle adjustable region refers to the mesh on the basis of the first antenna angle
Mark antenna is around adjustable region at the center, and the size in these regions is defined to first area value.
When the zone signal intensities in these the first adjustable-angle regions are obtained, can be by by the region in these regions
The signal intensity sum on summit as the region zone signal intensities.For example, region A has four regions summit, these tops
The corresponding aerial angle of point is respectively a1, a2, a3 and a4 so that, obtain respectively the corresponding signal intensity b1 of a1, a2, a3 and a4,
B2, b3 and b4, then the zone signal intensities of region A are b1+b2+b3+b4.
105th, determine that the first maximum angle adjustable region of the zone signal intensities is preferred communication area；
After the zone signal intensities for obtaining each the first angle adjustable region, it may be determined that the zone signal intensities
The first maximum angle adjustable region is preferred communication area.
106th, the preferable area is traveled through with default second step value according to target antenna described in default second path clustering
Domain；
After the preferred communication area is determined, can be according to target antenna described in default second path clustering with default
Second step value travels through the preferred communication area, and second step value is less than first step value.
It is understood that the present invention is after preferred communication area is determined, aerial angle is carried out in the preferred communication area
Thin choosing, therefore, second step value should be less than first step value.It is understood that second step value is smaller, then
The precision of thin choosing is higher.
In addition, the second above-mentioned path is similar with the design principle of above-mentioned first path, here is omitted.
107th, obtain what the target antenna was received on each aerial angle during the preferred communication area is traveled through
Signal intensity；
Can obtain what the target antenna was received on each aerial angle during the preferred communication area is traveled through
Signal intensity, the principle with above-mentioned steps 102 is similar, and here is omitted.
108th, determine that the maximum aerial angle of the signal intensity received during the preferred communication area is traveled through is second
Aerial angle；
After the signal intensity that the target antenna is received on each aerial angle is obtained, it may be determined that in traversal
The aerial angle of the signal intensity maximum received during the preferred communication area is the second aerial angle.
It is understood that because preferred communication area is typically small, traveling through the time-consuming it is considered that can connect of the preferred communication area
In the range of receiving, in order to get the aerial angle of signal intensity maximum in preferred communication area, the present invention can during thin choosing then
Not use the method for stopping ergodic process, directly after the completion of traversal, the maximum aerial angle of signal intensity is defined as the
Two aerial angles.
109th, the target antenna is positioned to second aerial angle.
In the present embodiment, after the second aerial angle is determined, the target antenna can be positioned to described second
Aerial angle, namely think that the second current aerial angle is best angle, antenna positioning is completed.
Further, in the present embodiment, the target antenna is positioned to before second aerial angle, can be with
Including：Judge whether predeterminable event meets default location condition, if so, step 109 is then performed, if it is not, then again going into
Carefully select process.
Further, wherein, it is described to judge whether predeterminable event meets default location condition and include：Judge institute
State whether the corresponding signal intensity of the second aerial angle exceedes default Second Threshold；Or, judge the area of the preferred communication area
Whether domain signal intensity exceedes default 3rd threshold value.It is understood that before target antenna is positioned, this can be checked
Whether the communication quality of the second aerial angle meets the requirements or meets necessary demand, if being unsatisfactory for but positioning target antenna
To second aerial angle, then the quality of antenna communication is difficult to ensure that.Therefore, it is possible to judge that the corresponding letter of the second aerial angle
Whether number intensity exceedes default Second Threshold, if so, then it is considered that its requirement for meeting communication quality；Or, can sentence
Whether the zone signal intensities of the disconnected preferred communication area for determining second aerial angle exceed default 3rd threshold value, if so,
It is considered that it meets the requirement of communication quality.Wherein, Second Threshold and the 3rd threshold value can be carried out according to actually used situation
Setting.
Further, above-mentioned " again go into and carefully select process " can specifically include：
If 1) predeterminable event is unsatisfactory for default location condition, the regional signal in each the second angle adjustable region is obtained
Intensity, the second angle adjustable region is the area corresponding to the antenna angle adjustable on the basis of second aerial angle
Domain, and the area size in the second angle adjustable region is default second area value, the second area value is less than described
First area is worth；
2) determine that the second maximum angle adjustable region of the zone signal intensities is preferred communication area；
3) second step value is reduced into by a default stepping-in amount, is then back to perform step 106.
For above-mentioned steps 1), its principle is similar to above-mentioned steps 104.Wherein, due to the requirement of thin choosing, the second area
Value should be worth less than the first area, namely the regional extent in the second angle adjustable region is less than the first angle adjustable region
Regional extent.
For above-mentioned steps 2), its principle is similar to above-mentioned steps 105, and here is omitted.
For above-mentioned steps 3), because step value is smaller, then the precision of thin choosing is higher, therefore, carrying out again thin choosing
When, the second step value can be reduced by a default stepping-in amount, so as to improve precision when carefully selecting next time.In modification second step
Enter after value, execution step 106 can be returned, so that perform step 106~108 successively again, after obtaining again thin choosing
The second aerial angle.
If it is understood that after thin choosing obtains the second aerial angle again, the predeterminable event is still unsatisfactory for presetting
Location condition, then circulation next time can be carried out with " again go into and carefully select process ", successively perform step 1), 2), 3),
It is then back to perform step 106~108, by that analogy, so that realize circulating the function of thin choosing, until the predeterminable event meets pre-
If location condition, then target antenna is positioned to the second aerial angle.Further, extremely followed to prevent this method to be absorbed in
Ring, expends the time of process during thin choosing, can set the number of times of the thin choosing of circulation, when number of times exceedes limitation, for example, surpasses
When crossing 3 times, then circulation is jumped out automatically or directly execution step 109 is positioned to target antenna.
It is understood that in the present embodiment, in order to further optimize the process of the thin choosing of circulation, in above-mentioned steps 3) in,
The second area value can also be reduced by a default amount of area so that be circulated thin choosing, the preferable area for obtaining every time
Domain can be more and more accurate.

Due to being traveled through according to first vertical order horizontal again, it is vertical suitable again that the rotational time of antenna is shorter than first level
Sequence, therefore using first vertical order horizontal again during traversal.
Roughing is carried out first, whole solid space is searched for according to the horizontal interval and perpendicular separation of roughing, often cross between one
Every the signal intensity for obtaining current angular, it is compared with advantage (correspondence first that this point is recorded if now signal intensity is more than threshold value
Aerial angle) and the screening of optimal region is carried out, rotary electric machine is returned compared with advantage and exits roughing after the completion of screening, is otherwise judged
Whether it is more than known maximum signal, if then recording this angle for best angle, repeats this process until antenna is reached
