Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a self-excitation processing method and device, a storage medium and an electronic device. Background Art

[0002] Generally, there are two ways to determine self-excitation. One is based on the characteristics of the self-excitation signal. For example, when the signal has strong self-excitation, the power will be saturated instantly. However, due to the protection of the ALC mechanism, the signal can be observed to be constantly beating at the output port, and each beating can reach the maximum power that the hardware can withstand. Generally, the number of beatings will be counted within a certain period of time. When the number reaches a certain threshold, it is determined to be self-excitation. The second is to determine whether the power changes linearly. When the power exceeds a certain value, the gain is automatically reduced to a certain value. Self-excitation is determined by comparing the reduced gain and the change in power. After the self-excitation is successfully determined, the gain of the corresponding link is adjusted. Each system and link is processed independently without any relationship.

[0003] If the existing self-excitation processing method is judged based on the phenomenon generated by the self-excitation surface, there will be two very important disadvantages: first, the processing time is long, and the spatial signal or the artificially added signal will have sudden jumps. Therefore, the threshold of the number of jumps needs to sacrifice a certain time cost in order to distinguish between self-excitation and normal signals; second, the self-excitation judgment is risky and inaccurate. If there is a high-amplitude and unstable input signal, it is easy to misjudge it as self-excitation and process it, or when there is a high-amplitude and stable input signal, self-excitation occurs but the judgment is always unsuccessful. Summary of the invention

[0004] The purpose of the present invention is to provide a self-excitation processing method and device, a storage medium and an electronic device to solve the technical problem of inaccurate self-excitation determination in the prior art.

[0005] In order to achieve the above object, the present invention provides a self-excitation processing method, which comprises:

[0006] Obtain the real-time detection voltage or real-time power of the current self-excitation system;

[0007] When the real-time power is greater than the rated power, or the real-time detection voltage is greater than the rated detection voltage, the gain value of the current system is reduced according to the first preset attenuation value so that the real-time detection voltage is lower than the rated detection voltage;

[0008] Determining whether the real-time detection voltage satisfies a first self-excitation determination condition;

[0009] If satisfied, the self-excitation determination times are increased by one and the gain of the current system is restored to obtain the real-time detection voltage again;

[0010] Determining whether the real-time detection voltage satisfies a second self-excitation determination condition;

[0011] If it is satisfied, the number of self-excitation determinations is increased by 1 and the gain value of the current system is reduced according to the first preset attenuation value, and then the detection voltage is judged again whether it meets the first self-excitation determination condition, and so on. Each time the self-excitation is successfully determined, the number of self-excitations is increased by 1, otherwise the number is reset to zero and the self-excitation determination is exited;

[0012] When the number of self-excitation times is greater than or equal to a preset threshold, the first preset attenuation value is determined to be a determined self-excitation attenuation value.

[0013] Optionally, before obtaining the real-time detection voltage or real-time power of the current self-excitation system, the method further includes:

[0014] Obtain the rated power detection voltage and the first real-time detection voltage of the current self-excitation system;

[0016] If the rated power detection voltage is greater than the second real-time detection voltage, determining whether the second real-time detection voltage and the first real-time detection voltage meet a first self-excitation determination condition;

[0017] If the difference is greater than the first preset difference, the step of obtaining the real-time detection voltage or real-time power of the current self-excitation system is performed.

[0018] The first self-excitation determination condition is determined according to the Nth real-time detection voltage, the first preset attenuation value, the N-1th real-time detection voltage, the linear error, and the detection voltage variation coefficient. The Nth real-time detection voltage is recorded as V N , the N-1th real-time detection voltage V N-1 , the linear error is recorded as M, the detection voltage variation coefficient is recorded as S, and the first preset attenuation value is recorded as G, then the first self-excitation determination condition is:

[0019] G+M<(V N-1 -V N ) / S; N is greater than 0.

[0020] The second self-excitation determination condition is determined according to the Nth real-time detection voltage, the first preset attenuation value, the N+1th real-time detection voltage, the linear error, and the detection voltage variation coefficient. The Nth real-time detection voltage is recorded as V N , the N+1th real-time detection voltage V N+1 , the linear error is recorded as M, the detection voltage variation coefficient is recorded as S, and the first preset attenuation value is recorded as G, then the second self-excitation determination condition is:

[0021] G+M<(V N+1 -V N ) / S; N is greater than 0.

[0022] Optionally, when the number of self-excitation times is greater than or equal to a preset threshold, after the step of determining the first preset attenuation value as a determined self-excitation attenuation value, the method further includes:

[0023] The first self-excitation timing is started, and when the timing ends, the self-excitation system is controlled to release and decay according to the self-excitation decay value.

[0024] In order to achieve the above object, the present invention further proposes a self-excitation processing method, which is used for a plurality of linked self-excitation systems, and the self-excitation processing method comprises:

[0025] Obtaining a gain value of the self-excitation system after at least one self-excitation process;

[0026] Determine the gain value of the first self-excitation system having the smallest first gain value among all the first self-excitation systems as the preset gain value;

[0027] Acquire second gain values ​​of a plurality of second self-excitation systems that have not been self-excited;

[0028] For each second self-excited system,

[0029] When the second gain value is greater than the preset gain value;

[0030] Determining a current degree of isolation between the second self-excitation system and the first self-excitation system;

[0031] The self-excitation linkage attenuation value of the current second self-excitation system is determined according to the isolation, the second gain value and the preset gain value.

[0032] In order to achieve the above object, the present invention further provides a self-excitation processing device, the self-excitation processing device comprising:

[0033] Sampling module, obtaining the Nth real-time detection voltage or real-time power of the current self-excitation system;

[0034] A judgment module, when the real-time power is greater than the rated power, judges whether the N-th real-time detection voltage satisfies the first self-excitation judgment condition, judges whether the N-th real-time detection voltage satisfies the second self-excitation judgment condition, and judges the magnitude relationship between the number of self-excitation times and a preset threshold;

[0035] The control module, when the N-1th real-time detection voltage is greater than the rated detection voltage, reduces the gain of the current system according to the first preset attenuation value and then obtains the Nth real-time detection value; when the Nth real-time detection voltage meets the first self-excitation judgment condition, restores the gain value of the current system, increases the number of self-excitation judgments by 1, and obtains the N+1th real-time detection voltage; when the N+1th real-time detection voltage meets the second self-excitation judgment condition, reduces the gain value of the current system according to the first preset attenuation value and continues to judge; when the number of self-excitation times is greater than or equal to the preset threshold, determines that the first preset attenuation value is a determined self-excitation attenuation value; and when the number of self-excitation times is less than the preset threshold and does not meet the self-excitation judgment condition, clears the number of self-excitation judgments and exits the judgment.

[0036] In order to achieve the above object, the present invention further proposes a storage medium, wherein at least one executable instruction is stored in the storage medium, and when the executable instruction is executed on an electronic device, the electronic device executes the operation of the self-excitation processing method as described above.

[0037] In order to achieve the above object, the present invention further proposes an electronic device, comprising: a processor, a memory, a communication interface and a communication bus, wherein the processor, the memory and the communication interface communicate with each other through the communication bus;

[0038] The memory is used to store at least one executable instruction, and the executable instruction enables the processor to execute the operation of the self-excitation processing method as described above.

[0039] The present invention obtains the real-time detection voltage or real-time power of the current self-excitation system; when the real-time power is greater than the rated power, or the real-time detection voltage is greater than the rated detection voltage, the gain of the current system is reduced according to a first preset attenuation value so that the real-time detection voltage is lower than the rated detection voltage, and then it is judged whether the real-time detection voltage meets the first self-excitation determination condition; if it meets, the gain value of the current system is restored, and the number of self-excitation determinations is increased by 1, and the real-time detection voltage is re-acquired; it is judged whether the real-time detection voltage meets the second self-excitation determination condition; if it meets, the gain value of the current system is reduced according to the first preset attenuation value, and so on; when the number of self-excitations is greater than or equal to a preset threshold, the first preset attenuation value is determined to be a determined self-excitation attenuation value; the above scheme judges whether the first self-excitation determination condition and the second self-excitation determination condition are met for multiple times to realize multiple gain reduction and gain restoration processes, and accumulates the number of self-excitations when the judgment is successful, so that the accuracy of the self-excitation determination can be fully ensured, thereby solving the technical problem of inaccurate self-excitation determination in the prior art.

[0044] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0045] In order to solve the technical problem of inaccurate self-excitation determination in the prior art, the present invention provides a self-excitation processing method and device, a storage medium and an electronic device.

[0046] In one embodiment, if Figure 1 As shown, the self-excitation processing method comprises:

[0047] S1. Obtain the real-time detection voltage or real-time power of the current self-excitation system;

[0048] In a self-excitation system, the real-time detection voltage or real-time power can be obtained in real time through a feedback circuit or a corresponding type of acquisition circuit. It should be noted that the self-excitation system actually refers to a system with a complete self-excitation working circuit. In the self-excitation system, the gain value can be adjusted by sampling and feedback. In addition, the real-time power of the equipment can also be calculated by the detection voltage according to our calibration. For example, we can calibrate the detection voltage to 1000, which corresponds to an output power of 10dBm, so these two values ​​are the same concept here. Any acquisition of one of them can achieve the purpose of this application.

[0049] S2. When the real-time power is greater than the rated power, or the real-time detection voltage is greater than the rated detection voltage, the gain value of the current system is reduced according to the first preset attenuation value so that the real-time detection voltage is lower than the rated detection voltage;

[0050] When the real-time power is greater than the rated power, it indicates that the system may be self-excited and the gain needs to be reduced. This is a preliminary determination process, so the changes in the real-time detection voltage under various conditions can be considered.

[0051] S3, judging whether the real-time detection voltage satisfies the first self-excitation condition;

[0052] The judgment process may be performed N times, and in the Nth time, if N is an odd number, it is judged whether the real-time detection voltage satisfies the first self-excitation judgment condition, otherwise it is judged whether the real-time detection voltage satisfies the second self-excitation judgment condition;

[0053] S4. If satisfied, the number of self-excitation judgments is accumulated once and the current system gain is restored;

[0054] If the Nth judgment is satisfied, the number of self-excitation judgments is increased by 1. If N is an odd number, the gain of the current system is restored, otherwise the gain value of the current system is reduced according to the first preset attenuation value; if the number of self-excitation judgments is lower than the preset threshold, the process returns to S4 to repeat the judgment. The restoration at this time corresponds to the previous reduction in gain value. When the original signal has a sudden change or other changes, a certain judgment condition at this time will not be satisfied, thereby exiting the judgment process to avoid misjudgment.

[0055] S5, judging whether the real-time detection voltage satisfies the second self-excitation determination condition;

[0056] S6, if satisfied, then accumulate 2 self-excitation judgment times and reduce the system gain according to the first preset attenuation value, and then judge again whether the detection voltage meets the first self-excitation judgment condition, and so on, each time the self-excitation number is successfully judged to be increased by 1, otherwise the number is reset to zero and the self-excitation judgment is exited;

[0057] S7. When the number of self-excitation times is greater than or equal to a preset threshold, determine that the first preset attenuation value is a determined self-excitation attenuation value.

[0058] Through the above process, multiple determination processes can be accumulated, so that the determination process is more accurate. It should be noted that when the number of self-excitations is less than the preset threshold or does not meet the self-excitation determination condition, the number of self-excitation determinations is cleared and the determination is exited.

[0059] The above scheme determines whether the first self-excitation determination condition and the second self-excitation determination condition are met multiple times to achieve multiple gain reduction and gain restoration processes, and accumulates the number of self-excitation times when the judgment is successful. In this way, the accuracy of the self-excitation determination can be fully ensured, thereby solving the technical problem of inaccurate self-excitation determination in the prior art.

[0060] It should be noted that the above scheme uses the characteristics of self-excitation positive feedback amplification, and the above self-excitation processing method can only be determined when the output power is greater than the rated power.

[0061] In one embodiment, if Figure 2 As shown, before obtaining the real-time detection voltage or real-time power of the current self-excitation system, the method further includes:

[0062] S11, obtaining the rated power detection voltage and the first real-time detection voltage of the current self-excitation system;

[0063] S12: if the first real-time detection voltage is greater than the rated power detection voltage, reduce the gain value of the current system according to the first preset attenuation value, and obtain the second real-time detection voltage;

[0064] If the first real-time detection voltage is greater than the rated power detection voltage, it indicates that the self-excitation system at this time needs to reduce the gain value. If it is less than the rated power detection voltage, it indicates that the self-excitation system is in a state where the gain value does not need to be reduced. Through the above judgment, misjudgment can be avoided.

[0065] S13, if the rated power detection voltage is greater than the second real-time detection voltage, determine whether the second real-time detection voltage and the first real-time detection voltage meet the first self-excitation determination condition;

[0066] Wherein, when the rated power detection voltage is less than the second real-time detection voltage, otherwise continue to increase the value of the first preset attenuation value to re-obtain the second real-time detection voltage and perform this step again;

[0067] S14. If the second real-time detection voltage and the first detection voltage meet the first self-excitation judgment condition, increase the number of self-excitation judgments by one and restore the system gain to obtain the third detection voltage, and determine whether the third detection voltage and the second detection voltage meet the second self-excitation judgment condition.

[0068] The above process is the process before obtaining the real-time detection voltage or real-time power of the current self-excitation system. Through the above process, the voltage condition of the self-excitation system at this time can be preliminarily determined. A preliminary prediction can be achieved through a relatively simple processing process, reducing the requirements for hardware.

[0069] Optionally, the first self-excitation determination condition is determined according to the Nth real-time detection voltage, the first preset attenuation value, the N-1th real-time detection voltage, the linear error, and the detection voltage variation coefficient, and the Nth real-time detection voltage is recorded as V N , the N-1th real-time detection voltage V N-1 , the linear allowable error is recorded as M, the detection voltage variation coefficient is recorded as S, and the first preset attenuation value is recorded as G, then the first self-excitation determination condition is:

[0070] G+M<(V N-1 -V N ) / S; N is greater than 0.

[0071] Optionally, the second self-excitation determination condition is determined according to the Nth real-time detection voltage, the first preset attenuation value, the N+1th real-time detection voltage, the linear error, and the detection voltage variation coefficient, and the Nth real-time detection voltage is recorded as V N , the N+1th real-time detection voltage V N+1 , the linear error is recorded as N, the detection voltage variation coefficient is recorded as S, and the first preset gain value is recorded as G, then the second self-excitation determination condition is:

[0072] G+M<(V N+1 -V N ) / S; N is greater than 0.

[0073] Based on the above embodiments, the principle of the present application is described below with N=4:

[0074] Obtain the fourth real-time detection voltage of the current self-excited system;

[0075] Determining whether the fourth real-time detection voltage satisfies a first self-excitation determination condition;

[0076] At this time G+M<(V3-V4) / S

[0077] If satisfied, restore the gain value of the current system according to the first preset attenuation value, increase the number of self-excitation determinations by one, and obtain the fifth real-time detection voltage;

[0078] Determining whether the fifth real-time detection voltage satisfies a second self-excitation determination condition;

[0079] At this time G+M<(V5-V4) / S

[0080] If satisfied, the self-excitation judgment times are increased by one and the gain value of the current system is reduced according to the first preset attenuation value;

[0081] When the number of self-excitation times is greater than or equal to a preset threshold, determining the first preset attenuation value as a determined self-excitation attenuation value;

[0082] S7. When the number of self-excitation times is less than the preset threshold value and does not meet the judgment condition, the number of self-excitation judgment times is cleared and the judgment is exited.

[0083] Specifically, the above process is as follows: the first real-time detection voltage is sampled and recorded as V1, then the gain is reduced to make the output lower than the rated power, and the reduced gain is recorded as G. At this time, the second real-time detection voltage is recorded as V2, and the detection voltage change coefficient, that is, the detection voltage corresponding to each dB gain, is known as S. In theory, in the case of non-self-excitation, there is a relationship: G = (V1-V2) / S, if in the case of self-excitation, there is: G < (V1-V2) / S, but in fact, due to the difference in linearity of hardware devices, a variable linear tolerance M is required to assist in the judgment, so the judgment relationship for the establishment of self-excitation becomes: the first self-excitation judgment condition G + M < (V1-V2) / S. After the first linearity self-excitation judgment is established, the gain is restored, and the third real-time detection voltage is recorded as V3. At this time, the self-excitation judgment relationship becomes: the second self-excitation judgment condition G + M < (V3-V2) / S, the two together are 2 times of self-excitation judgment. In order to reduce the probability of misjudgment, the number of self-excitation judgments is more appropriate to be more than 4 times. If the linearity determination is not satisfied once, the determination will be exited. After all determinations are successful, the gain G will be reduced to complete a self-excitation process. In order to prevent the device from misjudging or isolation changes during actual application, the self-excitation process needs to be successful four times before the gain can be maintained in a safe state.

[0084] In the above embodiment, multiple self-excitation processing mechanisms are used to cooperate with each other for processing, so the processing speed is greatly improved. Or the above method is more accurate in judging unstable beating signals, and it is not easy to misjudge the self-excitation generation conditions.

[0085] In one embodiment, when the number of self-excitation times is greater than or equal to a preset threshold, after the step of determining the first preset attenuation value as a determined self-excitation attenuation value, the step further includes:

[0086] The first self-excitation timing is started, and when the timing ends, the self-excitation system is controlled to release and decay according to the self-excitation decay value.

[0087] In an exemplary technology, since the self-excitation of the uplink signal will directly interfere with the base station, and the stability of the uplink signal amplitude is lower than that of the downlink signal, the processing of the uplink signal is more important or more difficult than that of the downlink. In order to avoid self-excitation in the uplink, the ALC linkage method is adopted, that is, when the downlink power reaches the rated power, the attenuation applied needs to be linked to the uplink, so as to always ensure that the uplink gain is lower than the downlink. In some devices where the uplink and downlink gains are relatively close or the self-excitation processing requirements are relatively strict, even the early ALC linkage method is adopted, that is, the uplink has begun to reduce the gain when the downlink has not yet reached the rated power. When the uplink gain is lower than the downlink gain, there may be a situation where the uplink has not reached self-excitation, but the downlink has already processed self-excitation. At this time, the self-excitation attenuation value needs to be linked to the uplink to ensure that the uplink gain is always lower than the downlink gain. The linear self-excitation judgment method cannot effectively judge self-excitation when the actual effective signal amplitude is high, and the effect of relying solely on this method is not ideal.

[0088] In order to achieve the above purpose, Figure 3 As shown, the present invention further proposes a self-excitation processing method, which is used for a plurality of linked self-excitation systems, and the self-excitation processing method comprises:

[0089] S10, obtaining a gain value of the self-excitation system after at least one self-excitation process;

[0090] S20, determining the gain value of the first self-excitation system with the smallest first gain value among all the first self-excitation systems as the preset gain value;

[0091] S30, obtaining second gain values ​​of a plurality of second self-excitation systems that have not been self-excited;

[0092] For each second self-excitation system, when the second gain value is greater than the preset gain value;

[0093] S40, determining the current isolation degree between the second self-excitation system and the first self-excitation system;

[0094] S50, determining a self-excitation linkage attenuation value of the current second self-excitation system according to the isolation, the second gain value and the preset gain value.

[0095] In the above embodiment, taking a dual-system device as an example, the dual-system device includes a first self-excitation system and a second self-excitation system. When the gain of the first self-excitation system after self-excitation processing is G, the gain of the second self-excitation system is H. In the current environment, the isolation of the first self-excitation system is greater than the isolation of the second self-excitation system by K. If H+K>G, regardless of whether the second self-excitation system is self-excited or not, the self-excitation linkage attenuation value that the second self-excitation system needs to be linked is (H+K-G). It should be noted here that K will also be different for different system frequencies and in different test environments. When multiple systems process self-excitation linkage, after the isolation compensation caused by frequency and environment, the minimum gain Gmin in the system where the self-excitation processing is successful should be found first, and the minimum gain Gmin should be set to the preset gain value, and then Gmin should be used to compare with the gain of each system. Each self-excitation system with a gain higher than Gmin needs to be linked with the corresponding self-excitation linkage attenuation value to reduce the gain to Gmin, so as to prevent or eliminate those self-excitations that cannot be handled. By adding multiple linkage methods, the uplink self-excitation can be effectively prevented and handled, while also reducing the possibility of self-excitation that cannot be handled, thereby improving the availability of the equipment.

[0096] In order to solve the above problems, the present invention further proposes a self-excitation processing device, the self-excitation processing device comprising:

[0097] Sampling module, obtaining the Nth real-time detection voltage or real-time power of the current self-excitation system;

[0098] A judgment module, when the real-time power is greater than the rated power, judges whether the N-th real-time detection voltage satisfies the first self-excitation judgment condition, judges whether the N-th real-time detection voltage satisfies the second self-excitation judgment condition, and judges the magnitude relationship between the number of self-excitation times and a preset threshold;

[0099] A control module, when the N-1th real-time detection voltage is greater than the rated detection voltage, the gain of the current system is reduced according to the first preset attenuation value and then the Nth real-time detection value is obtained; when the Nth real-time detection voltage meets the first self-excitation judgment condition, the gain value of the current system is reduced according to the first preset attenuation value, and the number of self-excitation judgments is increased by 1 to obtain the N+1th real-time detection voltage; when the N+1th real-time detection voltage meets the second self-excitation judgment condition, the number of self-excitation judgments is increased by 1 and the gain value of the current system is restored to continue the judgment; when the number of self-excitations is greater than or equal to the preset threshold, the first preset gain value is determined to be the determined self-excitation attenuation value; and when the number of self-excitations is less than the preset threshold and the self-excitation judgment fails, the number of self-excitations is cleared and the judgment is exited.

[0100] The above scheme determines whether the first self-excitation determination condition and the second self-excitation determination condition are met multiple times to achieve multiple gain reduction and gain restoration processes, and accumulates the number of self-excitations when the determination is successful. In this way, the accuracy of the self-excitation determination can be fully ensured, thereby solving the technical problem of inaccurate self-excitation determination in the prior art.

[0101] In order to solve the above problem, the present invention further proposes a storage medium, wherein at least one executable instruction is stored in the storage medium. When the executable instruction is executed on an electronic device, the electronic device executes the operation of the self-excitation processing method as described above.

[0102] It should be noted that, since the storage medium of the present application includes all the steps of the above-mentioned self-excitation processing method, the storage medium can also implement all the schemes of the self-excitation processing method and have the same beneficial effects, which will not be repeated here.

Some or all of the modules may be selected according to actual needs to achieve the purpose of the present embodiment. It can be understood by those of ordinary skill in the art that all or some steps and systems in the method disclosed above can be implemented as software, firmware, hardware and appropriate combinations thereof. Some physical components or all physical components may be implemented as software executed by a processor, such as a central processing unit, a digital signal processor or a microprocessor, or implemented as hardware, or implemented as an integrated circuit, such as an application-specific integrated circuit. Such software may be distributed on a computer-readable medium, which may include a computer storage medium (or non-transitory medium) and a communication medium (or temporary medium). As known to those of ordinary skill in the art, the term computer storage medium includes volatile and non-volatile, removable and non-removable media implemented in any method or technology for storing information (such as computer-readable instructions, data structures, program modules or other data). Computer storage media include, but are not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile disk (DVD) or other optical disk storage, magnetic cassettes, magnetic tapes, magnetic disk storage or other magnetic storage devices, or any other medium that can be used to store the desired information and can be accessed by the computer. In addition, it is well known to those skilled in the art that communication media generally contain computer-readable instructions, data structures, program modules, or other data in a modulated data signal such as a carrier wave or other transport mechanism, and may include any information delivery media.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
