Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
As described in the background, in practical applications, the branches between the initial signal source and the synthesizer inevitably have differences, for example, the length of the connecting line, the thickness of the lead, the device parameters and the performance differences may cause the difference in power and phase of the branch signals sent to the input side of the synthesizer, and therefore, the power after power synthesis may be low and may not meet the use requirement.
In view of this, the embodiments of the present application provide a power combining method, which adjusts the power and the phase of the signal amplifying branch by obtaining the power output by the combiner, so as to maximize the power output by the combiner.
It should be noted that the power combining method provided by the present application can be applied to an electronic device 100, and fig. 1 illustrates a schematic structural block diagram of the electronic device 100 provided by the embodiment of the present application, where the electronic device 100 includes a memory 102, a processor 101, and a communication interface 103, and the memory 102, the processor 101, and the communication interface 103 are electrically connected to each other directly or indirectly to implement data transmission or interaction.

It will be appreciated that the configuration shown in FIG. 1 is merely illustrative and that electronic device 100 may include more or fewer components than shown in FIG. 1 or have a different configuration than shown in FIG. 1. The components shown in fig. 1 may be implemented in hardware, software, or a combination thereof.
The power combining method provided by the embodiment of the present application is exemplarily described below with the electronic device 100 as a schematic execution subject. The electronic device 100 may be the controller 210 in the power combining system 200, as shown in fig. 2, the power combining system 200 further includes a plurality of signal amplifying branches 220 and a combiner 230, the controller 210 and the combiner 230 are electrically connected to each signal amplifying branch 220, and the controller 210 is further electrically connected to the combiner 230.
As an implementation manner, referring to fig. 3, the power combining method includes:
and S102, controlling the signal amplification branch circuit to work.
And S104, taking one of the signal amplification branches as a target branch, and acquiring the output power of the target branch.
And S106, acquiring the power output by the synthesizer in real time, and adjusting the power and the phase of the other signal amplification branches one by one according to the output power of the target branch and the power output by the synthesizer so as to maximize the power output by the synthesizer.
As an implementation manner, each signal amplification branch 220 includes a synchronous signal source and a signal amplification unit, the controller 210 communicates with the synchronous signal source through a communication bus, and the controller 210 sets parameters such as frequency, power, phase, and output waveform of each synchronous signal source through the communication bus.
When the controller 210 controls each signal amplification branch 220 to operate, the synchronous signal source outputs a small power signal, and then the small power signal is amplified by the signal amplification unit and then a radio frequency power signal is output, and the multiple radio frequency power signals are synthesized by the synthesizer 230 and then output.
Meanwhile, optionally, the power combining system 200 further includes a first detection unit and a second detection unit, the first detection unit is respectively connected to the output end of the signal amplifying branch 220 and the controller 210, the second detection unit is respectively connected to the output end of the combiner 230 and the controller 210, the first detection unit is configured to feed back the power output by the signal amplifying branch 220 to the controller 210, and the second detection unit is configured to feed back the power output by the combiner 230 to the controller 210, so that the controller 210 can receive the power output by the signal amplifying branch 220 and the power output by the combiner 230 in real time.
Generally, the power of the signal amplification branches 220 can be maximized when the power is in the same amplitude and phase. That is, the power output by the signal amplification branches 220 is equal, and the phases are also equal, the synthesized power can reach the maximum. Therefore, as an implementation manner, in order to adjust the power of each signal amplifying branch 220 more conveniently, in an actual operation process, one of the signal amplifying branches 220 may be used as a target branch, and the power and the phase of the other signal amplifying branches 220 are adjusted according to the output power of the target branch, so that the power output by the combiner 230 can reach the maximum.
For example, the power combining system 200 includes 6 signal amplifying branches, which are numbered 01 and 02 … 06, respectively, and when the path for amplifying the signal # 01 is taken as the target branch, the output power of the signal amplifying branch # 01 can be used to adjust the power and phase of the other signal amplifying branches.
As an implementation manner, there may be only one first detecting unit, that is, only one detecting unit needs to be connected to the output end of the target branch, and when the signal amplifying branch 220 operates, the first detecting unit may feed back the output power of the target branch to the controller 210. As another implementation manner, the number of the first detecting units may be the same as the number of the signal amplifying branches 220, so that the output end of each signal amplifying branch 220 is connected to one first detecting unit, and the controller 210 can obtain the power output by each signal amplifying branch 220 through the first detecting units. By arranging the first detector unit and the second detector unit, the controller 210 can monitor the power variation of the total power output by the synthesizer 230 when the parameter of any synchronous signal source is regulated. Through the matching connection relationship of the controller 210, the synchronous signal source, the first detection unit and the second detection unit in the system, closed-loop power regulation can be realized, and a structural basis which is easy to regulate is provided for obtaining the maximum output power.
In the actual power combining, the output power of the combiner 230 can be maximized by adjusting the signal amplifying branches one by one. For example, if the number of the signal amplification branches is 6, and the signal amplification branch numbered 01 is used as the target branch, after the output power of the target branch is obtained, the power and the phase of the signal amplification branch No. 02 may be determined according to the power of the signal amplification branch No. 01, then the power and the phase of the signal amplification branch No. 03 may be determined, and so on until the power and the phase of all the signal amplification branches are determined.
On this basis, as an implementation manner, referring to fig. 4, S106 includes:
s1061, determining a fixed power of another signal amplifying branch according to the output power of the target branch, wherein the fixed power of the another signal amplifying branch is equal to the output power of the target branch.
And S1062, adjusting the phase of the other signal amplification branch, acquiring the output power of the synthesizer in real time, and determining the fixed phase of the other signal amplification branch when the output power of the synthesizer is maximum.
And S1063, repeating the step of determining the fixed power and the fixed phase of the next signal amplification branch until the fixed power and the fixed phase of all the signal amplification branches are determined, so as to maximize the power output by the synthesizer.
In this application, the other signal amplification branch refers to any signal amplification branch other than the target branch, for example, if the branch 01 is the target branch, the other signal amplification branch may refer to the branch 02 or the branch 03.
In theory, the power output by the combiner 230 can be maximized when the power and phase of the output of all signal amplification branches are the same. Therefore, after the power of the target branch is obtained, the power of the target branch can be used as the fixed power of other branches, so that the other branches operate according to the fixed power, and then the phase is adjusted.
For example, when the output power of the branch No. 01 is determined to be P1, the synchronous signal source in the branch No. 02 may be power-adjusted, and the output power P2 of the branch No. 02 may be received until the output power P2 of the branch No. 02 is adjusted to be equal to the output power P1 of the branch No. 01, and then the phase of the branch No. 02, that is, the phase of the synchronous signal source, is adjusted. In the phase adjustment process, the total power P output by the synthesizer 230 at each phase point is obtained in real time through the second detection unit, and the phase corresponding to the maximum total power P obtained in the current phase adjustment process is selected as the fixed phase of the second branch. At this time, the adjusting process of the second branch is finished, and power adjustment and phase adjustment are performed on branch 03, and so on until power adjustment and phase adjustment of all branches are completed.
In addition, on the basis of the present implementation, when power and phase adjustment is performed, there may be two ways:
firstly, all signal amplification branches are controlled to work, and the output power and the phase of each branch are adjusted in sequence. For example, when the number of branches is 6, the controller 210 controls 6 branches to operate simultaneously, the branch No. 01 is taken as a target branch, and when the power and phase of the branch No. 02 are adjusted, the remaining branches operate normally.
Second, only the regulated branch is controlled to operate, and the remaining branches are in a non-operating state. For example, when the number of branches is 6, the controller 210 first controls the branch 01 to operate, and obtains the output power of the branch 01 as a target branch. Then, the branch 02 is controlled to operate, and the remaining branches are in a non-operating state, that is, only the branch 01 and the branch 02 in the power combining system 200 operate at this time, the output power of the branch 02 is adjusted to be the same as the output power of the branch 01, then the phase of the branch 02 is adjusted, and the fixed phase of the branch 02 is determined when the power output by the combiner 230 is maximum. Then, the branch 03 is opened again, and the steps of adjusting the power and the phase are repeated until the power of all the branches is adjusted.
As another implementation manner, referring to fig. 5, S106 includes:
and S1064, determining the fixed power of all the signal amplification branches according to the output power of the target branch, wherein the fixed power of each signal amplification branch is equal to the output power of the target branch.
And S1065, adjusting the phase of the other signal amplification branch, acquiring the output power of the synthesizer in real time, and determining the fixed phase of the other signal amplification branch when the output power of the synthesizer is maximum.
S1066, repeating the step of determining the fixed phase of the next signal amplifying branch until the fixed phases of all signal amplifying branches are determined, so as to maximize the power output by the combiner.
That is, in this implementation manner, after the output power of the target branch is obtained, the output power of all branches can be determined by using the output power of the target branch, and then the phase of each branch is determined in sequence.
For example, when the branch 01 is the target branch, and after the output power of the branch 01 is determined to be P1, power adjustment may be performed on the remaining branches according to the output power P1 of the target branch, that is, the power P2 and the power P3 … P6 output by the remaining branches are obtained in real time. When the output power of all the branches is judged to be equal to the output power P1 of the target branch, the fixed power of all the branches is determined. And, at this time, the phase of the synchronous signal source in the branch No. 02 can be adjusted, in the phase adjustment process, the total power P output by the synthesizer 230 at each phase point is obtained, and the phase corresponding to the maximum total power P obtained in the phase adjustment process of this time is screened out as the fixed phase of the branch No. 02. At this point, the phase adjustment process for the second branch is ended. Then, the step of determining the fixed phase of the next signal amplification branch is repeated, i.e. phase adjustment for branch 03 is started. And by analogy, the phases of all the other branches are repeatedly adjusted, and the total power obtained when the phase adjustment process of all the branches is finished is the maximum. By the method, the maximum total power can be synthesized under fewer times of adjustment, and the power synthesis efficiency is improved.
Optionally, before performing power adjustment and phase adjustment, in order to reduce interference of a last parameter to the current power and phase adjustment, initialization may be performed first to empty original power and phase parameters.
Meanwhile, as an implementation manner, in order to further improve the efficiency of power synthesis, the controller 210 can obtain the phase of each signal amplification branch, that is, the controller 210 can obtain the phase of the synchronous signal source, and adjust the phases of the other signal amplification branches by coarse adjustment and fine adjustment according to the phase of the target branch.
That is, after obtaining the phase of the target branch, the controller 210 sequentially performs coarse adjustment and fine adjustment on the phase of each signal amplification branch. For example, if branch 01 is taken as the target branch, the phase of branch 01 may be obtained first, for example, the phase is X, and after the phase of branch 01 is obtained, when branch 02 is adjusted, the phase of branch 02 may be adjusted first, and then coarse adjustment and fine adjustment may be performed on the phase of branch 02.
Firstly, coarse adjustment is carried out, the phase of the branch 02 is also adjusted to be X, then the phase range of the branch 02 is adjusted according to a first numerical value, after the phase range is determined, the phase range of the branch 02 is adjusted according to a second numerical value, and the corresponding phase when the output power of the synthesizer 230 is maximum is taken as a target phase, wherein the first numerical value is larger than the second numerical value.
For example, the first value is 5 and the second value is 1, and during the adjustment, the adjustment is performed according to the values of X +5, X +10, X-5, and X-10, and the corresponding phase when the output power of the combiner 230 is maximum is determined. Then, fine adjustment is performed, that is, the phase corresponding to the maximum output power of the combiner 230 is determined according to the second value, for example, if the output power is maximum when X +5 is used, the phase of the 02 th branch is adjusted to be X +1, X +2, X +3, X +4, X +5, X +6, X +7, X +8, and X +9, and the phase of the maximum output power of the combiner 230 is taken as the fixed phase of the 02 th branch.
Through the implementation mode, the fixed phase of each branch can be efficiently determined.
Meanwhile, for the purpose of human-computer interaction, the power synthesis system 200 further includes a display 240, the display 240 is electrically connected to the controller 210, referring to fig. 6, after the step of S106, the method further includes:
and S108, transmitting the acquired output power and the maximum power output by the synthesizer 230 to a display 240 for displaying.
Optionally, the display 240 may be a touch screen display, so as to more conveniently realize human-computer interaction. In addition, the controller 210 may send the acquired data to the display 240 for displaying, so that the user can more intuitively see various indexes and parameters of the system, such as the output power of each branch and the power output by the combiner 230, through the display 240.
Meanwhile, in order to ensure the normal operation of the system, parameters of the system, such as voltage, current, temperature, etc., need to be acquired before or during the operation of the system, and after the parameters are acquired and matched, the controller 210 may also send the parameters to the display 240 for display.
Of course, the user may also adjust parameters, such as adjusting output power, via the display 240 or other input device.
Meanwhile, in an optional implementation manner, a user may also perform data regulation and control in a remote manner, and on this basis, the power combining system 200 further includes a terminal device 250, where the terminal device 250 is in communication connection with the controller 210. For example, the terminal device 250 is connected to the controller 210 through an RS485 interface or an ethernet interface, and a user can perform parameter setting and status viewing on the system through a remote interface. The terminal device 250 may be a mobile phone of a user, an intelligent device such as a computer, and the like.
That is, the controller 210 can receive the control command sent by the end device 250 and control the operating state of the signal amplifying branch according to the control command. For example, when the output power needs to be adjusted remotely, a user may send an adjustment instruction to the controller 210 through the smart device, and after receiving the adjustment instruction, the controller 210 adjusts the output power and the phase of each branch, thereby achieving the purpose of adjusting the output power of the combiner 230.
In an alternative implementation manner, when the output power of the target branch is greater than the first threshold, or the power output by the combiner 230 is greater than the second threshold, the controller 210 may further control each signal amplification branch to stop working, so as to perform a function of protecting the system.
Meanwhile, in the application, when the voltage, the current, the temperature, the power, the standing-wave ratio and other indexes of the system are not in the set safety range, the system can also send out an alarm signal and close the corresponding function to protect the system. The system can only be operated again when the corresponding warning signal is released.
Optionally, after receiving the data, the controller 210 may directly compare the data with a preset value, and when the parameter is within a preset value range, control each branch to operate normally; when the parameters are out of the preset value range, the power synthesis system 200 is controlled to stop working, and alarm information is displayed on the display 240 or an alarm signal is sent to the terminal device 250 remotely.
Also, the power synthesis system 200 includes a power enable button, and the controller 210 detects the power enable button. If the user turns on the power output, the controller 210 detects the on state and then detects each parameter of the system, and if each parameter is not abnormal, turns on the power output and continuously and cyclically detects the parameters of the system. If the controller 210 detects that the user is in a power-off state or detects that the system parameter is abnormal, the function enable is turned off to protect the system. When the fault is cleared, the user can restart the system.
Based on the foregoing implementation, an embodiment of the present application further provides a power combining apparatus 300, please refer to fig. 7, where the power combining apparatus 300 includes:
and a control unit 310 for controlling the signal amplification branch 220 to operate.
It is understood that S102 may be performed by the control unit 310.
The signal obtaining unit 320 is configured to take one of the signal amplifying branches 220 as a target branch, and obtain output power of the target branch.
It is understood that S104 may be performed by the signal acquisition unit 320.
