All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
In order to make the aforementioned objects, features and advantages of the embodiments of the present application more comprehensible, embodiments of the present application are described in detail below with reference to the accompanying drawings and the detailed description.
Referring to fig. 1, a flow chart of a communication control method provided in embodiment 1 of the present application is schematically illustrated, where the method may be applied to a processor of an electronic device, the electronic device includes the processor, an identification system and at least one set of directional antenna arrays, the identification system may be configured to identify object attribute information in any one direction, and the present application does not limit a product type of the electronic device, as shown in fig. 1, and the method may include, but is not limited to, the following steps:
and S101, obtaining object attribute information which is respectively recognized by a recognition system of the electronic equipment in a plurality of directions.
The plurality of directions may include at least: multiple emission directions available around the electronic device. The electronic device may radiate radio frequency signals in a plurality of transmission directions available around it.
In the application, the identification system in the electronic device can be set as required, and the specific structure of the identification system is not limited. However, at least, it needs to be ensured that the identification system has a function of identifying object attribute information in multiple directions, and the object attribute information can reflect whether the object has influence on the radio frequency signals radiated by the directional antenna array.
Specifically, the recognition system may be any one or more of a radar system, an infrared system, and a camera system. The object attribute information identified by the radar system, the infrared system and the camera system has difference.
Step S102, determining a direction with the influence degree on the radio frequency signal radiated by the directional antenna array higher than a threshold value in a plurality of directions based on the object attribute information in each direction.
Under the condition that the object attribute information can reflect whether the object affects the radio-frequency signals radiated by the directional antenna array, the influence of various objects on the radio-frequency signals radiated by the directional antenna array can be quantified in advance, the influence degree of each object on the radio-frequency signals radiated by the directional antenna array is obtained, and the corresponding relation between the object attribute information of each object and the influence degree of each object on the radio-frequency signals radiated by the directional antenna array is established.
The influence of multiple objects on the radio-frequency signal radiated by the directional antenna array is quantified in advance, and the degree of influence of each object on the radio-frequency signal radiated by the directional antenna array can be obtained, including but not limited to:
the method comprises the steps of respectively deploying each object in the radiation direction of a directional antenna array, controlling the directional antenna array to radiate radio-frequency signals in the radiation direction of the directional antenna array, collecting the radio-frequency signals passing through the objects, carrying out operation processing on the radio-frequency signals radiated by the directional antenna array and the collected radio-frequency signals passing through the objects to obtain loss values of the radio-frequency signals radiated by the antenna array, and taking the ratio of the loss values of the radio-frequency signals radiated by the antenna array to the radio-frequency signals radiated by the antenna array as the degree of influence of the objects on the radio-frequency signals radiated by the directional antenna array.
Specifically, the intensity of the radio-frequency signal after passing through the object may be collected, an operation (e.g., subtraction operation) may be performed on the intensity of the radio-frequency signal radiated by the directional antenna array and the collected intensity of the radio-frequency signal after passing through the object to obtain an intensity loss value of the radio-frequency signal radiated by the antenna array, and a ratio of the intensity loss value of the radio-frequency signal radiated by the antenna array to the intensity of the radio-frequency signal radiated by the antenna array is used as an influence degree of the object on the radio-frequency signal radiated by the directional antenna array.
On the basis of pre-establishing the corresponding relation between the object attribute information of each object and the influence degree of the object attribute information on the radio-frequency signals radiated by the directional antenna array, the influence degree matched with the object attribute information identified by the identification system in each direction can be searched in the pre-established corresponding relation between the object attribute information of various objects and the influence degree of the object attribute information on the radio-frequency signals radiated by the directional antenna array, after the matched influence degree is found, the influence degree matched with the object attribute information identified by the identification system in each direction is compared with the threshold value to obtain a comparison result, and the direction in which the influence degree on the radio-frequency signals radiated by the directional antenna array is higher than the threshold value in the directions is determined based on the comparison result.
The threshold may be set as needed, and is not limited in this application.
It can be understood that the directional antenna array may increase the loss of the rf signal radiated by the directional antenna array if the directional antenna array radiates in a direction that affects the rf signal radiated by the directional antenna array to a degree higher than the threshold value.
In this embodiment, the directional antenna array may be, but is not limited to: a 4G directional antenna array or a 5G directional antenna array.
Step S103, controlling the directional antenna array to radiate in a specified direction, wherein the specified direction is different from at least a direction in which the influence degree of the radio-frequency signals radiated by the directional antenna array is higher than a threshold value.
After determining the direction in which the influence degree of the radio-frequency signal radiated by the directional antenna array is higher than the threshold, controlling the directional antenna array to radiate in the specified direction which is different from the direction in which the influence degree of the radio-frequency signal radiated by the directional antenna array is higher than the threshold, at least reducing the loss of the radio-frequency signal radiated by the directional antenna array.
In this embodiment, the directional antenna array is controlled to radiate in a specified direction, where the specified direction at least has a difference from a direction in which an influence of the radio frequency signal radiated by the directional antenna array is higher than a threshold, which may include but is not limited to:
and S10311, selecting one direction from directions having a difference with the direction in which the influence degree of the radio-frequency signal radiated by the directional antenna array is higher than the threshold value as a designated direction.
And S10312, controlling the directional antenna array to radiate in the appointed direction.
One direction is selected from directions different from the directions with the influence degrees higher than the threshold value of the radio-frequency signals radiated by the directional antenna array to serve as the designated direction, so that the efficiency of selecting the designated direction can be improved, and the efficiency of radiating the directional antenna array in the designated direction is improved.
It should be noted that, although one direction is selected from directions different from the directions in which the radio frequency signals radiated by the directional antenna array have a degree of influence higher than the threshold value, as a manner of specifying the direction, the efficiency of the directional antenna array radiating in the specified direction can be improved, but the manner of random selection cannot ensure that the selected specified direction can certainly meet the strength requirement of the signals received by the receiving end.
In order to solve the problem in the random selection manner, this embodiment provides another implementation manner, specifically, the controlling the directional antenna array to radiate in a specified direction, where the specified direction is different from at least a direction in which a radio frequency signal radiated to the directional antenna array is influenced by a degree higher than a threshold value, and the implementing manner may include:
and S10321, respectively transmitting signals to the target object by using each direction which has a difference with the direction of the radio frequency signals radiated to the directional antenna array and has the influence degree higher than the threshold value.
S10322, obtaining signals received by the target object from each direction having a difference with the direction in which the influence degree of the radio frequency signal radiated from the directional antenna array is higher than the threshold, and measuring the obtained measurement result, where the measurement result at least includes signal strength.
Based on the signal strength in the measurement result obtained by the target object measurement, it can be determined whether the direction having a difference with the direction having an influence degree higher than the threshold value on the radio frequency signal radiated by the directional antenna array meets the signal strength requirement of the receiving end.
S10323, if at least one of the signal strengths is greater than the set signal strength threshold, selecting a direction from the directions having a difference from the directions in which the influence of the radio frequency signal radiated from the directional antenna array is greater than the threshold, and the direction in which the signal strength is greater than the set signal strength threshold, as the designated direction.
The set signal strength threshold may be set as needed, and is not limited in this application.
In this embodiment, if one of the signal strengths is greater than the set signal strength threshold, the direction in which the influence of the radio frequency signal radiated from the directional antenna array is greater than the threshold may be regarded as the designated direction.
If a plurality of signal strengths among the plurality of signal strengths are all greater than the set signal strength threshold, one direction may be randomly selected as the designated direction from a plurality of directions in which the influence degree of the radio frequency signal radiated to the directional antenna array is greater than the threshold, and the signal strength is greater than the set signal strength threshold.
Of course, if a plurality of signal strengths among the plurality of signal strengths are all greater than the set signal strength threshold, a direction with the greatest signal strength may be selected as the designated direction from among the plurality of directions in which the radio frequency signal radiated from the directional antenna array has a greater influence than the threshold, and the signal strength is greater than the set signal strength threshold.
And S10324, controlling the directional antenna array to radiate in the appointed direction.
The direction with the influence degree higher than the threshold value is different from the direction of the radio-frequency signal radiated by the directional antenna array, and one direction with the maximum signal intensity is selected from a plurality of directions with the signal intensity higher than the set signal intensity threshold value to be used as the designated direction, and the directional antenna array is controlled to radiate in the designated direction, so that the signal received by the receiving end is more optimal.
In this embodiment, each direction having a difference with the direction having the influence degree higher than the threshold from the radio frequency signal radiated by the directional antenna array is used to transmit a signal to a target object, and a measurement result obtained by measuring a signal received by the target object from each direction having a difference with the direction having the influence degree higher than the threshold from the radio frequency signal radiated by the directional antenna array is obtained. For example, as shown in fig. 2(a), if the electronic device adopts the beam scanning method in the prior art, the electronic device needs to perform beam scanning in 5 directions (t 1, t2, t3, t4, and t5, respectively), and determines one direction from t1, t2, t3, t4, and t5 to communicate with the target object, specifically, t4 to communicate with the target object. As shown in fig. 2(b), after determining that t1 and t2 are directions having a degree of influence on the radio frequency signal radiated by the directional antenna array higher than the threshold from among the 5 directions, the electronic device does not perform beam scanning on t1 and t2, but performs beam scanning on t3, t4, and t5, and determines that one direction is determined from among t3, t4, and t5 to communicate with the target object, specifically, determines that t4 communicates with the target object. Compared with the prior art that beam scanning is carried out in 5 directions, the beam scanning direction can be reduced, and the directional communication efficiency is accelerated.
In addition, the directional antenna array is controlled to radiate in a specified direction, where the specified direction has a difference from at least the direction in which the radio frequency signal radiated to the directional antenna array is influenced by a degree higher than a threshold, and the method may also include, but is not limited to:
s10331, respectively transmitting signals to the target object in each direction having a difference from the direction in which the influence degree of the radio frequency signal radiated to the directional antenna array is higher than the threshold.
S10332, obtaining signals received by the target object from each direction having a difference with the direction in which the influence degree of the radio frequency signal radiated from the directional antenna array is higher than the threshold, and measuring the obtained measurement result, where the measurement result at least includes signal strength.
S10333, if at least one of the signal strengths is greater than the set signal strength threshold, selecting a direction from the directions having a difference with the direction in which the influence degree of the rf signal radiated from the directional antenna array is greater than the threshold, and the direction in which the signal strength is greater than the set signal strength threshold, as the designated direction.
And S10334, controlling the directional antenna array to radiate in the appointed direction.
The detailed procedures of steps S10331 to S10334 can be referred to in the related description of steps S10321 to S10324, and will not be described herein.
S10335, if the signal intensities are not greater than the set signal intensity threshold, selecting a direction from directions having a difference from the directions in which the influence degrees of the radio frequency signals radiated from the directional antenna array are greater than the threshold, as the designated direction.
S10336, the directional antenna array is controlled to radiate in the appointed direction, and the radio frequency signals radiated by the directional antenna array in the appointed direction are subjected to enhancement processing, so that the intensity of the radio frequency signals received by the signal receiving end in the appointed direction is improved.
If the signal intensity is not greater than the set signal intensity threshold value, selecting one direction from directions different from the directions of the radio-frequency signals radiated by the directional antenna array and having the influence degrees higher than the threshold value as a specified direction, controlling the directional antenna array to radiate in the specified direction, and reducing the loss of the radio-frequency signals radiated by the directional antenna array.
As another optional embodiment of the present application, referring to fig. 3, which is a flowchart of a communication control method provided in embodiment 2 of the present application, this embodiment mainly details a refinement scheme of the communication control method described in embodiment 1 above, and as shown in fig. 3, the method may include, but is not limited to, the following steps:
step S21, obtaining object attribute information recognized by the recognition system of the electronic device in a plurality of directions respectively.
Step S22, determining, based on the object attribute information in each direction, a direction in the plurality of directions in which the degree of influence on the radio frequency signal radiated by the directional antenna array is higher than a threshold.
The detailed procedures of steps S21-S22 can be found in the related descriptions of steps S11-S12 in embodiment 1, and are not repeated herein.
Step S23, determining, in the electronic device, a directional antenna array matched with the designated direction in the multiple directional antenna arrays when the electronic device includes multiple sets of directional antenna arrays and the multiple sets of directional antenna arrays are distributed in different areas of the electronic device.
Determining a directional antenna array that matches a given direction in a plurality of sets of directional antenna arrays may include, but is not limited to: and determining the directional antenna array of which the overlapping area of the signal coverage range and the specified direction is in the set range in the multi-group directional antenna array, and taking the directional antenna array of which the overlapping area of the signal coverage range and the specified direction is in the set range as the directional antenna array matched with the specified direction.
If the overlapping area of the signal coverage range and the designated direction is in multiple groups of directional antenna arrays in the set range, the directional antenna array with the largest overlapping area with the designated direction in the multiple groups of directional antenna arrays with the overlapping area of the signal coverage range and the designated direction in the set range is used as the directional antenna array matched with the designated direction. Now, referring to fig. 4, a directional antenna array matching a specified direction is described, as shown in fig. 4, an overlapping area between a signal coverage area of the directional antenna array 1 distributed in the first area of the electronic device and the specified direction t4 is a1, a signal coverage area of the directional antenna array 2 distributed in the second area of the electronic device can completely cover the specified direction t4, that is, an overlapping area b1 between the signal coverage area of the directional antenna array 2 and the specified direction t4 is a coverage area of a signal radiated in the specified direction t4, and a1 is smaller than b1, then the directional antenna array 2 is selected as the directional antenna array matching the specified direction.
It should be noted that fig. 4 is only an example, and is not intended to limit the distribution of the directional antenna array and the relationship between the directional antenna array and the designated direction.
And step S24, controlling the directional antenna array matched with the specified direction to radiate in the specified direction.
In this embodiment, the directional antenna array matched with the designated direction is controlled to radiate in the designated direction, so that the loss of radio frequency signals radiated by the directional antenna array can be further reduced.
As another optional embodiment of the present application, referring to fig. 5, a flowchart of a communication control method provided in embodiment 3 of the present application is provided, and this embodiment mainly details a refinement scheme of the communication control method described in embodiment 1 above, as shown in fig. 5, the method may include, but is not limited to, the following steps:
and step S31, obtaining the electromagnetic wave characteristic information respectively recognized by the radar system of the electronic equipment in a plurality of directions.
The radar system identifies electromagnetic wave characteristic information in each direction by radiating radio frequency signals to a plurality of directions. The electromagnetic wave characteristic information may be understood as: information relating to physical phenomena (e.g., reflection, diffraction, absorption, or transmission, etc.) that occur when a radio frequency signal radiated by a radar system encounters an object.
The electromagnetic wave characteristic information may include, but is not limited to: any one or more of electromagnetic wave reflectivity, electromagnetic wave absorptivity, electromagnetic wave transmissivity, electromagnetic wave diffraction rate and electromagnetic wave reflection spectrum.
Step S31 is a specific implementation manner of step S11 in example 1.
And step S32, determining the direction blocked by an obstacle in a plurality of directions based on the electromagnetic wave characteristic information in each direction, wherein the obstacle can influence the radio frequency signal radiated by the directional antenna array.
Based on the electromagnetic wave characteristic information in each direction, determining the direction in which the obstacle is blocked in a plurality of directions can be understood as follows:
s3201, calculating electromagnetic wave characteristic information in each direction to obtain information of an obstacle (e.g., information of a material, a size, and a position of the obstacle), where the information of the obstacle can reflect whether the obstacle can affect the radio frequency signal radiated by the directional antenna array, and if the information of the obstacle is a metal, the obstacle of the metal can affect the radio frequency signal radiated by the directional antenna array.
S3202, determining, based on the information of the obstacle, a direction in which the obstacle exists, which may affect the radio frequency signal radiated by the directional antenna array, from among the plurality of directions.
It is understood that S3201-S3202 may be performed to determine the direction in which an obstacle exists in a plurality of directions, in case that the frequency band of the radar system is a fixed value and does not match the frequency band used by the directional antenna array, or in case that the frequency band of the radar system is adjustable.
Certainly, under the condition that the frequency band of the radar system is adjustable, the frequency band of the radar system can be adjusted to be the frequency band matched with the frequency band used by the directional antenna array, when the frequency band of the radar system is matched with the frequency band used by the directional antenna array, the radar system radiates radio-frequency signals in each direction, the identified electromagnetic wave characteristic information is equivalent to the electromagnetic wave characteristic information which can be obtained when the directional antenna array radiates the radio-frequency signals in each direction. Therefore, whether the direction is blocked by the obstacle can be determined only based on the electromagnetic wave characteristic information, and the radio-frequency signal radiated by the directional antenna array can be determined to be influenced by the direction if the direction is blocked by the obstacle. In the whole process, the information such as the size, the material and the like of the barrier does not need to be solved, and the efficiency of determining the designated direction can be accelerated
It can be understood that the directional antenna array has the function of radiating radio frequency signals to each direction, but does not have the function of identification, so that external system coordination is required. In addition, the radar system has the function of radiating the radio-frequency signals related to the properties of the radio-frequency signals radiated by the directional antenna array and the function of identifying, and can be used as a preferred external system to cooperate with the directional antenna array, so that the directional communication efficiency of the electronic equipment is improved.
The frequency band of the radar system is adjusted to match the frequency band used by the directional antenna array, which may include but is not limited to: adjusting the frequency band of the radar system to be a frequency band which has a difference in a set frequency band range with the frequency band used by the directional antenna array; or, the frequency band of the radar system is adjusted to be the same as the frequency band used by the directional antenna array.
The electromagnetic wave characteristic information includes: in the case of the electromagnetic wave reflectivity, determining a direction in which an obstacle is blocked from among a plurality of directions based on the electromagnetic wave characteristic information in each direction may include:
s3211, respectively determining whether the reflectivity of the electromagnetic wave in each direction is greater than a reflectivity threshold.
If yes, it is determined that the transmission of the radio frequency signal is affected by an excessively high radio frequency signal radiated by the radar system reflected by the object, then step S3212 is performed.
The reflectivity threshold can be set as desired, and is not limited in this application.
And S3212, setting the direction as a direction in which an obstacle blocks.
The electromagnetic wave characteristic information includes: in the case of a magnetic wave reflection spectrum, determining a direction in which an obstacle exists among a plurality of directions based on electromagnetic wave characteristic information in each direction may include:
s3221, comparing the electromagnetic wave reflection spectrum in each direction with the electromagnetic wave reflection spectrum corresponding to the human body, respectively, to obtain a comparison result.
