Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus consistent with some aspects of the disclosure as detailed in the accompanying claims.
Currently, smartphones require various performance tests, such as antenna performance tests, before shipment. Among them, there is an important index SAR (Specific Absorption Rate, electromagnetic wave absorption ratio, i.e., electromagnetic radiation energy absorbed by a substance of unit mass in unit time) for antenna performance.
In the related art, the SAR test method generally adopts a scheme of reducing the transmitting power of the smart phone, so that the SAR value can be reduced. However, after The transmission power is reduced, the total radiation power (Total Radiated Power, TRP) of The smart phone is also reduced, so that The performance standard requirements of The smart phone for network access or Air-to-Air download technology test (OTA) cannot be met.
In order to solve the above-mentioned problems, the embodiments of the present disclosure provide a power adjustment method, which is suitable for adjusting the transmission power in the testing process of an electronic device, and the invention is characterized in that according to the different testing laboratories (such as a shielding laboratory or an unshielded laboratory) where the electronic device is located in different performance tests, the received spatial electrical noise signal intensities are different, and according to the received spatial electrical noise signal intensities, the performance testing environment in which the electronic device is located can be determined, so that the respective required transmission power of each performance testing environment can be determined according to the different performance testing environments. In other words, the embodiment can preset the signal strength threshold in the electronic device to achieve the above scheme.
Fig. 1 is a flow chart illustrating a power adjustment method according to an exemplary embodiment. Referring to fig. 1, a power adjustment method includes steps 101 to 103, wherein:
in step 101, the spatial electrical noise signal strength of the environment in which the electronic device is located is obtained.
In this embodiment, the electronic device may include a modem, a radio frequency chip, a radio frequency link, an antenna switch and an antenna, referring to fig. 2, where the antenna is connected to the antenna switch, and the radio frequency link is disposed between the antenna switch and the radio frequency chip, and the modem is connected to the radio frequency chip. Taking the received signal as an example, the antenna may receive a spatial electrical noise signal of an environment in which the electronic device is located, where the spatial electrical noise signal arrives at the modem via the antenna switch, the radio frequency link, and the radio frequency chip. The modem can process the spatial electrical noise signal to obtain spatial electrical noise signal strength. Also, the modem may communicate with a processor (not shown) in the electronic device, sending this spatial electrical noise signal strength to the processor.
In step 102, the spatial electric noise signal intensity is compared with a preset signal intensity threshold value, and an intensity comparison result is obtained.
In this embodiment, the electronic device may preset a signal strength threshold, where the signal strength threshold may include a signal strength value and may further include a signal strength range. The preset signal strength threshold is obtained through the following steps, referring to fig. 3, including:
the electronic device is placed in a pre-set non-shielded laboratory, the effect of which is shown in fig. 4, wherein a non-shielded laboratory means that a spatial electromagnetic wave signal distributed in space can penetrate the laboratory to reach the surroundings of the electronic device to be tested, so that an antenna of the electronic device can receive the spatial electromagnetic wave signal. A modem within the electronic device may then process the spatial electromagnetic wave signal to obtain a spatial electrical noise signal strength, i.e., a first spatial electrical noise signal strength. Thus, the processor may obtain a first spatial electrical noise signal strength (corresponding to step 301 in fig. 3).
It can be appreciated that, since the space electromagnetic wave signal is filled around the antenna during the test, the intensity of the first space electrical noise signal obtained by processing will be relatively high, and this scenario can be applied to SAR testing of electronic devices. The principle of SAR testing can be found in the related art, and will not be described herein.
The electronic device is placed in a preset shielding laboratory, the effect of which is shown in fig. 5, wherein the shielding laboratory comprises a metal plate enclosed outside the laboratory and a wave-absorbing material arranged inside the laboratory, so that an external spatial electromagnetic wave signal cannot enter the laboratory. In this way, the antenna of the electronic device can receive the spatial electromagnetic wave signals from the reflected signals of its own emitted signals. A modem within the electronic device may then process the spatial electromagnetic wave signal to obtain a spatial electrical noise signal strength, i.e., a second spatial electrical noise signal strength. I.e. the processor may obtain a second spatial electrical noise signal strength (corresponding to step 302 in fig. 3).
In general, a shielded laboratory shields the electromagnetic wave signals in space outside the laboratory compared to an unshielded laboratory, and therefore, the second electromagnetic wave signal strength is smaller than the first electromagnetic wave signal strength. In the testing process, the external space electromagnetic wave signals cannot enter the shielding laboratory, so that the space electromagnetic wave signals around the antenna are fewer, the strength of the second space electric noise signals obtained through processing is smaller, and the method can be applied to OTA testing of electronic equipment. The principle of OTA test can be referred to in the related art, and will not be described herein.
It should be noted that, in this embodiment, the order of acquiring the first spatial electric noise signal strength and the second spatial electric noise signal strength by the processor is not limited, the first spatial electric noise signal strength may precede the second spatial electric noise signal strength, the first spatial electric noise signal strength may follow the second spatial electric noise signal strength, and under the same condition of two electronic devices, the first spatial electric noise signal strength and the second spatial electric noise signal strength may be acquired simultaneously.
The processor may then determine an intensity value between the first spatial electrical noise signal intensity and the second spatial electrical noise signal intensity as a signal intensity threshold (corresponding to step 303 of fig. 3). One of the intensity values may be selected from a location intermediate the first spatial electrical noise signal intensity and the second spatial electrical noise signal intensity or more toward the second spatial electrical noise signal intensity. In addition, in consideration of that when the first spatial electric noise signal intensity is obtained, the spatial electromagnetic wave signal of the environment where the electronic device is located may change, so in this embodiment, a plurality of first spatial electric noise signal intensities may be obtained at different positions, and the minimum first spatial electric noise signal intensity or an average value of the plurality of first spatial electric noise signal intensities may be used as the final first spatial electric noise signal intensity.
In this embodiment, after the processor obtains the spatial electrical noise signal strength, the spatial electrical noise signal strength may be compared with a preset signal strength threshold to obtain a comparison result. Wherein the comparison result includes the spatial electrical noise signal strength being less than the signal strength threshold and the spatial electrical noise signal strength being greater than the signal strength threshold.
If the signal strength threshold is a signal strength range, the spatial electrical noise signal strength is smaller than the signal strength threshold, which means that the spatial electrical noise signal strength is smaller than or equal to the minimum value of the signal strength range, and the spatial electrical noise signal strength is greater than the signal strength threshold, which means that the spatial electrical noise signal strength is greater than or equal to the maximum value of the signal strength range.
In step 103, the transmitting power of the electronic device is adjusted according to the comparison result.
In this embodiment, the processor may adjust the transmitting power of the electronic device according to the comparison result, including:
in an example, if the comparison result indicates that the spatial electric noise signal strength is smaller than the signal strength threshold, the processor decreases the transmission power of the electronic device to a preset first transmission power to meet the requirement of the SAR test. The preset first transmission power may be selected according to the SAR test requirement, which is not limited herein.
In another example, if the comparison indicates that the spatial electrical noise signal strength is greater than the signal strength threshold, the processor maintains the transmit power of the electronic device to meet the requirements of the OTA test.
So far, in the embodiment of the disclosure, the spatial electric noise signal intensity of the environment where the electronic equipment is located is obtained; then, comparing the signal intensity with preset signal intensity to obtain a comparison result; and then, the transmitting power of the electronic equipment can be adjusted according to the comparison result, so that the transmitting power meets the requirement of the test process. Therefore, the embodiment can determine a signal strength threshold according to different performance tests, and prestore the signal strength threshold in the electronic equipment, so that the transmitting power required by each performance test can be determined according to the strength of the space electromagnetic wave signal in the process of testing the electronic equipment, a corresponding detection device is not required, and the implementation is simple and convenient, and the test cost can be reduced. In addition, in the embodiment, the electronic equipment automatically adjusts the emission intensity under different performance tests, so that the accuracy of the detection result is improved.
