Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
An embodiment of the present invention provides a power control method, referring to fig. 1, including the following steps:
step 101, obtaining the power of a first output signal of the terminal to obtain first power.
The first output signal is obtained by processing a first signal to be processed generated by the terminal.
Specifically, step 101 obtains the power of the first output signal of the terminal, and the obtaining of the first power may be implemented by the terminal. The terminal may be a wireless signal transmitting terminal capable of performing power control for transmitting a wireless signal, for example, may be a wireless router, a mobile phone capable of generating a local area network hotspot, or the like. The terminal obtains the total power of the self output signal of the terminal according to feedback to obtain first power; i.e. the first output signal is a radio signal transmitted by the antenna system of the terminal at the previous moment adjacent to the current moment. The first signal to be processed may be an original signal generated by a controller in the terminal according to preset parameters, which may be a fixed signal or a signal which is changed according to user requirements, and is fixed before the next modification. For example, the first signal to be processed may be a signal obtained by the wireless router identifying a network signal provided by the network operator.
Step 102, calculating a difference between the first power and the preset power.
Specifically, the step 102 of calculating the difference between the first power and the preset power may be implemented by the terminal. The preset power is a preset power of an output signal output by a desired terminal.
Step 103, obtaining second adjustment information according to the difference value and a preset threshold value.
Specifically, step 103 may be implemented by the terminal to obtain the second adjustment information according to the difference value and the preset threshold value. The preset threshold value is obtained by carrying out statistical analysis on the difference value between the variable to be adjusted, namely the power of the output signal and the preset power when the power of different output signals in different application scenes is required to be adjusted to different preset powers through a large number of experiments, determining the corresponding preset threshold value, and determining corresponding second adjustment information when the different preset threshold values are different, so that the relation obtained by optimally adjusting the output signals to the expected output signals at least times is realized. The second adjustment information may be information for instructing the terminal to adjust the impedance used to control the resulting output signal, including a control signal for instructing the terminal to increase or decrease the impedance and a corresponding impedance variable to be adjusted.
Step 104, obtaining first adjustment information.
Specifically, step 104 of obtaining the first adjustment information may be implemented by the terminal. The first adjustment information may be information for instructing the terminal to adjust the gain of the first signal to be processed, and includes the gain of the first signal to be processed of the terminal, a control signal for increasing or decreasing the gain, and a corresponding gain variable value to be adjusted. The first adjustment information may be sent to the terminal by the user, or may be obtained by the terminal through analysis and determination according to a specific use condition. Preferably, the terminal may acquire the first adjustment information according to a relationship between a difference between the first power and the preset power and a preset threshold.
The execution sequence between the steps 102-103 and the step 104 is not consecutive, the step 104 may be performed before the steps 102-103, or the steps 102-103 and the step 104 may be selected to be performed simultaneously, and the specific execution sequence may be determined according to an actual application scenario.
Step 105, adjusting the power of the first signal to be processed based on the first adjustment information to obtain a second signal to be processed.
Specifically, step 105 adjusts the power of the first signal to be processed based on the first adjustment information, and the obtaining of the second signal to be processed may be implemented by the terminal. And the terminal adjusts the gain of amplifying the power of the first signal to be processed based on the first adjustment information, and then amplifies the power of the first signal to be processed based on the adjusted gain to obtain a second signal to be processed. Here, the coarse adjustment of the first signal to be processed is equivalent to quickly adjusting the power of the first signal to be processed to a certain range of the preset power.
And step 106, adjusting the power of the second signal to be processed based on the second adjustment information to obtain a second output signal.
Specifically, step 106 adjusts the power of the second signal to be processed based on the second adjustment information, and the obtaining of the second output signal may be implemented by the terminal. After the terminal obtains the second signal to be processed, the controllable impedance in the circuit outputting the second signal to be processed is adjusted by adopting the second adjustment information, and the second signal to be processed is output after the impedance is adjusted, so that the power of the second signal to be processed is finely adjusted, and the power of the obtained output signal, namely the second output signal, is close to the preset power as much as possible.
According to the power control method provided by the embodiment of the invention, after the power of the first output signal is obtained to obtain the first power, the difference value between the first power and the preset power is calculated, and according to the difference value and the preset threshold value, second adjustment information is obtained, meanwhile, the first adjustment information is obtained, then the power of the first signal to be processed is adjusted based on the first adjustment information to obtain a second signal to be processed, and the power of the second signal to be processed is adjusted based on the second adjustment information to obtain a second output signal; in this way, the terminal determines the first adjustment information and the second adjustment information according to the power of the previous output signal of the terminal, adjusts the first signal to be processed generated by the terminal by using the first adjustment information to obtain the second signal to be processed, adjusts the second signal to be processed by using the second adjustment information to obtain the current output signal, solves the problem that the transmitting signal power of the wireless signal generating terminal cannot be accurately controlled in the prior art, ensures that the wireless signal transmitting terminal can accurately adjust the power of the output signal, ensures the information transmission efficiency of the wireless signal, and reduces the influence of the radiation intensity of the wireless signal transmitting terminal on the surrounding environment.
Based on the foregoing embodiments, an embodiment of the present invention provides a power control method, as shown in fig. 2, where the method for obtaining the power of the first output signal of the terminal and obtaining the first power includes the following steps:
step 101a, the terminal acquires a sub-signal from the first output signal.
Specifically, taking a terminal as a wireless router and an output signal as a wireless signal as an example for explanation, the terminal obtains a part of signals in a first output signal which is currently output from an output end of the terminal, and obtains the sub-signal. The terminal can use a coupler to couple the first output signal according to a certain coupling ratio, and couple the first output signal into two paths of signals, preferably, in order not to influence the signal power of the terminal to be transmitted to other terminals, the proportion of sub signals fed back to the terminal by the terminal is smaller. For example, one can follow 1: and 9, carrying out coupling processing on the first output signal according to the coupling proportion to obtain two paths of signals with the proportion of 1/10 and 9/10, wherein the terminal can select the signal with the proportion of 1/10 as a feedback signal to obtain the sub-signal.
And 101b, the terminal acquires the power of the sub-signal to obtain second power.
Specifically, when the sub-signal is obtained after coupling, the terminal may measure the power of the sub-signal at the output end to obtain the second power, and record the specific power value as the second power for feedback, or may receive the sub-signal as the feedback signal at the receiving end of the terminal, and then measure the power of the feedback signal at the receiving end of the terminal to obtain the second power.
Step 101c, the terminal calculates the second power to obtain the first power based on the proportional relation between the sub-signal and the first output signal.
Specifically, the proportional relationship between the sub-signal and the first output signal may be a proportion of the sub-signal in the first output signal when the terminal feeds back the sub-signal, for example, may be a coupling proportion adopted by the coupler. Can be represented by formula P 2 ＝λP 1 Calculating to obtain a first power, wherein P 1 Representing the total power of the first output signal, i.e. the first power, P 2 The power of the sub-signal, i.e. the second power, is represented, and lambda represents the proportional relation between the sub-signal and the first output signal. For example, in the case of 1:9, when the coupling ratio of the first output signal is used for coupling processing, determining that the ratio relation lambda between the sub-signal and the first output signal is 1/10, and when the power of the sub-signal is P 2 At the time, the power of the first output signal is the first power
Based on the foregoing embodiments, as shown in fig. 3, when the embodiment of the present invention is mainly applied to an application scenario where the difference is greater than the first threshold when the preset threshold is the first threshold, the method for acquiring the second adjustment information according to the difference and the preset threshold includes the following steps:
step 103a, if the difference is greater than the first threshold, the terminal generates a first control signal.
The preset threshold is a first threshold, the first threshold is larger than zero, and the first control signal is used for indicating the terminal to reduce the power of the second signal to be processed.
Specifically, since the first threshold is greater than zero, the difference is also greater than zero, which indicates that the power of the first output signal is greater than the preset power, and the power of the output signal of the terminal needs to be reduced, the terminal may generate a first control signal that instructs the terminal to reduce the power of the second signal to be processed to reduce the power of the output signal of the terminal. Wherein the first control signal may be generated by the controller of the terminal, the controller of the terminal may send the first control signal to the reverse impedance variable tuning system in the terminal impedance tuner to reduce the power of the second signal to be processed by reducing the output impedance, since the first control signal is indicative of reducing the power of the second signal to be processed. The first threshold may be an empirical value obtained through a number of experiments and actual use.
And 103b, acquiring a first impedance value corresponding to the difference value by the terminal according to the relation between the difference value and the impedance value variable.
Specifically, the first impedance value and the first control signal constitute second adjustment information. The relation between the difference value and the impedance value variable can be an impedance value which is determined by statistics in advance and is corresponding to the difference value between different first powers and preset powers and is needed to be adjusted on the impedance of the terminal, so that after the difference value between the first powers and the preset powers is obtained by calculation, the terminal obtains the impedance value corresponding to the difference value according to the relation between the difference value and the impedance value variable, and the first impedance value is obtained. The first impedance value may be obtained by the controller of the terminal.
Based on the foregoing embodiments, an embodiment of the present invention provides a power control method, as shown in fig. 4, where the method for adjusting the power of a second signal to be processed based on second adjustment information to obtain a second output signal includes the following steps:
and 106a, the terminal subtracts the first impedance value from the impedance value corresponding to the second signal to be processed according to the first control signal so as to reduce the power of the second signal to be processed, and a second output signal is obtained.
Specifically, since the first control signal is used for indicating to reduce the power of the second signal to be processed, the controller of the terminal controls the tuning switch in the impedance tuner to be connected with the reverse impedance variable tuning system so as to inform the impedance tuning system that the impedance needs to be reduced, and meanwhile, the controller of the terminal also informs the impedance tuner that the specific impedance value to be adjusted is the first impedance value. In this way, the reverse impedance variable tuning system of the impedance tuning system works normally, so that the terminal reduces the power of the second signal to be processed by reducing the impedance value corresponding to the second signal to be processed by the first impedance value, and a second output signal is obtained.
Based on the foregoing embodiments, as shown in fig. 5, when the embodiment of the present invention is mainly applied to an application scenario in which the difference is smaller than the second threshold when the preset threshold is the second threshold, the method for acquiring the second adjustment information according to the difference and the preset threshold includes the following steps:
step 103c, if the difference is smaller than the second threshold, the terminal generates a second control signal.
The preset threshold is a second threshold, the second threshold is smaller than zero, and the second control signal is used for indicating the terminal to increase the power of the second signal to be processed.
Specifically, if the second threshold is smaller than zero, the first output signal is smaller than the preset power, and the power of the output signal needs to be increased for the terminal, at this time, the controller of the terminal may generate a second control signal for indicating to increase the impedance corresponding to the second signal to be processed, and send the second control signal to the impedance tuner of the terminal.
And 103d, obtaining a second impedance value corresponding to the difference value by the terminal according to the relation between the difference value and the impedance value variable.
Wherein the second adjustment information includes a second impedance value and a second control signal.
Specifically, the controller of the terminal obtains an impedance variable value corresponding to the difference value based on the calculated difference value between the first power and the preset power, and obtains a second impedance value.
Based on the foregoing embodiments, an embodiment of the present invention provides a power control method, as shown in fig. 6, where the method for adjusting the power of a second signal to be processed based on second adjustment information to obtain a second output signal includes the following steps:
and step 106b, the terminal obtains a second output signal by adding the second impedance value to the impedance value corresponding to the second signal to be processed according to the second control signal so as to increase the power of the second signal to be processed.
Specifically, the impedance tuner of the terminal is connected with the tuning switch in the impedance tuner and the forward impedance variable tuning system based on the second control signal, so as to increase the impedance value corresponding to the second signal to be processed. Meanwhile, the controller of the terminal also sends a third resistance value to the forward impedance variable tuning system so as to inform the forward impedance variable tuning system that the specific impedance value to be increased is a second impedance value, and therefore the power of the second signal to be processed is increased by increasing the impedance value of the second signal to be processed, and a second output signal is obtained.
In this way, the terminal executes steps 103a-103b and 106a, or steps 103c-103d and 106b, because the power of the second signal to be processed is already very close to the preset power, if the power of the second signal to be processed is continuously adjusted by adjusting the gain, the adjustment is not easy to be the preset power value, so that the fine adjustment can be performed on the power of the second signal to be processed by adjusting the impedance value, thereby realizing rapid and accurate adjustment of the power of the second signal to be processed to the preset power, and improving the adjustment efficiency of adjusting the output signal power of the terminal.
Based on the foregoing embodiments, the embodiments of the present invention provide a power control method, and a method for obtaining first adjustment information may be specifically implemented by: acquiring first adjustment information according to the difference value and a preset threshold value; as shown in fig. 7, the method for obtaining the first adjustment information according to the difference value and the preset threshold value includes the following steps:
step 104a, if the difference is greater than the first threshold, the terminal generates a third control signal.
The preset threshold is a first threshold, the first threshold is larger than zero, and the third control signal is used for indicating the terminal to reduce the gain of amplifying the power of the first signal to be processed.
Specifically, since the first threshold is greater than zero, the power of the first output signal is greater than the preset power, in order to reduce the power of the output signal of the terminal, the terminal generates a control signal for instructing to adjust the gain of amplifying the power of the first signal to be processed, i.e., the controller of the terminal may generate a third control signal for instructing the terminal to reduce the gain of currently amplifying the power of the first signal to be processed, and send the third control signal to the power amplifier.
Step 104b, the terminal obtains a first gain corresponding to the difference value according to the relation between the difference value and the gain variable.
Wherein the first adjustment information includes a first gain and a third control signal.
Specifically, the relationship between the difference value and the gain variable may be a gain variable obtained by adjusting the gain of the amplified first signal to be processed when the difference value between the power of the different output signals and the preset power is obtained through a large number of experiments in advance, and the relationship between the difference value and the gain variable may be a list of the difference value and the gain variable, which may be stored in the terminal in advance. The relation between the difference and the gain variable may be based on a calculation formula between the power and the gain, so that the difference between the power of the first output signal and the preset power is calculated by adopting the calculation formula between the power and the gain, and a corresponding gain value is obtained as the first gain to be realized.
For example, a controller of the terminal calculates a difference between the first power and the preset power by using a calculation formula between the power and the gain, obtains a gain value corresponding to the difference, and sends the gain value to the power amplifier.
Based on the foregoing embodiments, an embodiment of the present invention provides a power control method, as shown in fig. 8, where the method for adjusting the power of a first signal to be processed based on first adjustment information to obtain a second signal to be processed includes the following steps:
Step 105a, the terminal reduces the gain corresponding to the first signal to be processed by the first gain according to the third control signal, and obtains the second gain.
Specifically, the gain corresponding to the first signal to be processed may be a gain fixedly set in the terminal for amplifying the power of the first signal to be processed. For example, according to the received third control signal, the power amplifier of the terminal performs a reduction process on the gain set by the power amplifier, specifically reduces the first gain, and obtains the second gain.
And 105b, amplifying the power of the first signal to be processed based on the second gain by the terminal to obtain a second signal to be processed.
Specifically, since the second gain is smaller than the gain corresponding to the first signal to be processed which amplifies the power of the first signal to be processed last time, the terminal amplifies the power of the first signal to be processed based on the second gain to obtain the second signal to be processed, and at this time, compared with the power of the first signal to be processed which amplifies the power of the first signal to be processed based on the gain of the first signal to be processed last time, the power of the obtained second signal to be processed is reduced. It should be noted that, after the terminal amplifies the power of the first signal to be processed based on the second gain, the second gain may be set to the gain corresponding to the first signal to be processed, but in some application scenarios, after the terminal amplifies the power of the first signal to be processed based on the second gain, the terminal recovers the gain to the gain corresponding to the first signal to be processed.
For example, the power amplifier of the terminal performs power amplification processing on the first signal to be processed based on the second gain, so as to obtain a second signal to be processed.
Based on the foregoing embodiments, an embodiment of the present invention provides a power control method, as shown in fig. 9, where the method for obtaining first adjustment information according to the difference value and the preset threshold value further includes the following steps:
and 104c, if the difference value is smaller than the second threshold value, the terminal generates a fourth control signal.
The preset threshold value comprises a second threshold value, the second threshold value is smaller than zero, and the fourth control signal is used for indicating the terminal to increase the gain of the first signal power to be processed.
And 104d, the terminal acquires a third gain corresponding to the difference value according to the relation between the difference value and the gain variable.
Wherein the first adjustment information includes a third gain and a fourth control signal.
Based on the foregoing embodiments, an embodiment of the present invention provides a power control method, as shown in fig. 10, where the method for adjusting the power of a first signal to be processed based on first adjustment information to obtain a second signal to be processed further includes the following steps:
step 105c, the terminal increases the gain corresponding to the first signal to be processed by the third gain according to the fourth control signal, so as to obtain a fourth gain.
And 105d, amplifying the power of the first signal to be processed by the terminal based on the fourth gain to obtain a second signal to be processed.
In the embodiment of the present invention, an application situation is further included, that is, when the difference between the power of the first output signal and the preset power is greater than the third threshold and less than the fourth threshold, the terminal may not need to obtain the first adjustment information to adjust the gain corresponding to the first signal to be processed, and continue to use the gain corresponding to the first signal to be processed (preferably, the gain corresponding to the first signal to be processed is the gain adjusted last time, but in some application scenarios, the gain corresponding to the first signal to be processed is the gain adjusted and then restored to the default setting), to amplify the power of the first signal to be processed, so as to obtain the second signal to be processed, and if the third threshold is greater than zero, the terminal may select to execute steps 103a-103b and 106a, and if the fourth threshold is less than zero, the terminal may select to execute steps 103c-103d and 106b.
In this way, the terminal executes steps 104a-104b and 105a-105b, or steps 104c-104d and 105c-105d, because the difference between the first power and the preset power satisfies the first threshold or the second threshold, which indicates that the difference between the first power and the preset power is large, because the power of the first signal to be processed is adjusted by adjusting the gain according to a certain proportion, the adjustment amplitude and the adjustment control range cannot accurately adjust the power of the first signal to be processed to the preset power, the power of the first signal to be processed can be coarsely adjusted by adjusting the gain of the first signal to be processed, so that the power of the first signal to be processed can be quickly adjusted to be close to the preset power, and the adjustment times can be reduced.

And step 108, the terminal determines preset power based on the output signal coverage parameter.
Specifically, the preset power may be preset power corresponding to different output signal coverage parameters. The terminal determines the preset power based on the output signal coverage parameter by searching the preset power corresponding to the signal coverage parameter in a corresponding table of the output signal coverage parameter and the preset power stored in the terminal based on the output signal coverage parameter, or by calculating according to a formula between the output signal coverage parameter and the preset power of the wireless signal expected to be output by the user. In this way, the preset power can be determined according to the specific use scene, so that the radiation intensity of the wireless device can be ensured to be within the set standard range, and the transmission rate of information is ensured.
