Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
Fig. 1 is a flowchart illustrating a method for setting antenna parameters according to an embodiment of the present invention. The antenna power setting method is used for setting the antenna power of at least one antenna 10 of the electronic device 100 to be set as shown in fig. 4. As shown in fig. 1, in an embodiment, the method for setting the antenna power includes the following steps.
A target antenna power value is determined (S101). The target antenna power value refers to an antenna power value corresponding to an SAR (Specific Absorption Rate) value just meeting a standard, for example, 22dbm, where "dbm" represents a value of an absolute value of power, and may be regarded as a ratio based on 1mW (milliwatt) of power, and in some embodiments, the target antenna power value may be directly obtained empirically, and in some embodiments, the target antenna power value may be obtained according to the method shown in fig. 2 below.
And determining a preset power value according to the target antenna power value, and adjusting the antenna power of at least one electronic device 100 to be set to the preset power value (S102). Wherein the preset power value may be equal to the target antenna power value or slightly less than the minimum value that is required to be met, e.g., when the target antenna power value is 22dbm, the preset power value may be 22dbm or 21 dbm. In some embodiments, the preset power value may be a preset percentage of the target antenna power value, for example, 95% or 98% of the target antenna power value, so that by setting the preset power value slightly lower than the target antenna power value, the SAR value is further ensured not to exceed the standard.
Therefore, in the present application, by determining the target antenna power value that any electronic device 100 needs to substantially satisfy, the antenna power value of the electronic device 100 is adjusted to the target antenna power value or slightly smaller than the target antenna power value, and the performance of the antenna can be ensured to the greatest extent while the SAR value is not over the standard. Therefore, in the production debugging process, it can be ensured that the electronic devices 100 in the same batch meet the safety standard and the antenna performance can be ensured as much as possible. Compared with the existing electronic device 100 with the maximum antenna power, the electronic device 100 determines the power value required to be reduced, and then reduces the power value for all other mobile phones, so that when the power of some electronic devices 100 is relatively low, the power is very low when the same power value is reduced, and all electronic devices 100 can be ensured to be in a state that the SAR value does not exceed the standard and the antenna performance is good as much as possible.
Fig. 2 is a flowchart of a method for setting antenna parameters according to another embodiment of the present invention. The difference with the embodiment shown in fig. 1 is that step S101 in fig. 1 is further refined. As shown in fig. 2, the method for setting the antenna parameters includes the following steps.
A predetermined number of electronic devices 100 are analyzed to determine an antenna power value for each electronic device 100 when the SAR value just meets the safety standard (S201). The preset number can be 100, 200 and the like, and the requirement of sample analysis accuracy can be met. The preset number of electronic devices 100 is a product having the same model as the at least one electronic device 100 to be set, and may be already set electronic devices or electronic devices 100 to be set.
The target antenna power value is determined according to the antenna power value of each electronic device 100 when the SAR value just meets the safety standard (S202). In some embodiments, the step S202 includes: and calculating the arithmetic mean value or the geometric mean value of the antenna power values of all the electronic devices 100 when the SAR value just meets the safety standard to obtain the target antenna power. In some embodiments, the step S202 includes: and sequencing the antenna power values of all the electronic devices 100 when the SAR value just meets the safety standard, and determining the antenna power value positioned at the middle as the target antenna power. For example, for 100 electronic devices 100, the antenna power values of the 100 electronic devices 100 when the SAR value just meets the safety standard are sorted, and if the antenna power value of the nth electronic device 100 when the SAR value just meets the safety standard is the middle of the antenna power values of the 100 electronic devices 100, the antenna power value of the nth electronic device 100 when the SAR value just meets the safety standard is determined to be the target antenna power value.
Determining a preset power value according to the target antenna power value, and adjusting the antenna power of at least one electronic device 100 to be set to the preset power value (S203). The preset power value may be equal to the target antenna power value or slightly smaller than the target antenna power value.
Steps S201 to S202 correspond to step S101 in fig. 1, and step S203 corresponds to step S102, and the corresponding points can be referred to each other.
Fig. 3 is a flowchart of a method for setting antenna parameters according to another embodiment of the present invention.

Specifically, step S303 includes: comparing the current antenna power value of each electronic device 100 to be set with the preset power value, thereby obtaining the difference between the antenna power value of each electronic device 100 to be set and the preset power value.
The antenna power value of each electronic device 100 to be set is controlled to be backed off by a corresponding difference value, and the antenna power value of each electronic device is adjusted to the preset power value (S304). Wherein the step S304 includes: if the current antenna power value of a certain electronic device 100 to be set is greater than the preset power value, the antenna power value of the electronic device 100 to be set is decreased by a corresponding difference value, and if the current antenna power value of the certain electronic device 100 to be set is less than the preset power value, the antenna power value of the electronic device 100 to be set is increased by a corresponding difference value.

The computer readable storage medium may be the aforementioned memory 30, or may be a storage medium to which the electronic device 100 is temporarily connected. For example, the computer-readable storage medium may be a memory card such as an SD card, and may be connected to the electronic apparatus 100 when debugging is required, or may be a micro hard disk, a hard disk, and the like, and may be connected to the electronic apparatus 100 through a USB data line or the like when debugging is required. The program instructions in the computer-readable storage medium are Auto-Run program instructions that are automatically invoked by the processor 20 to perform the aforementioned operations when the electronic device 100 is connected to the computer-readable storage medium.
