[0021] In the following description, specific details such as specific system structures and techniques are provided for purposes of illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, systems, circuits, and methods are omitted to avoid obscuring the description of the present application with unnecessary detail.
[0022] In order to make the purpose, technical solutions and advantages of this application clearer, specific embodiments will be described below with reference to the accompanying drawings.
[0023] Please refer to Figure 1 , Figure 1 This is a flow chart of a frequency conversion system switching control method provided in one embodiment of the present application. The method is applied to a first frequency conversion unit and includes:
[0024] S101: Determine an operating state of a second frequency conversion unit based on operating parameters of the second frequency conversion unit, wherein there are multiple second frequency conversion units, and each second frequency conversion unit corresponds to a signal transmission channel.
[0025] In this embodiment, the frequency conversion system switching control method can be applied to a communication base station. The first and second frequency conversion units can be upconverters. The first frequency conversion unit serves as a backup upconverter and is in a standby state. Multiple second frequency conversion units (main upconverters) each correspond to an independent signal transmission channel and perform signal frequency conversion during normal communication.
[0026] The first frequency conversion unit (backup upconverter) can continuously monitor the operating parameters of each second frequency conversion unit (main upconverter) in real time. The operating parameters of the second frequency conversion unit may include frequency accuracy, power stability, and signal purity.
[0027] Communication base stations have strict signal frequency requirements. The secondary frequency conversion unit must accurately convert the incoming intermediate frequency signal to the specified radio frequency. For example, if the RF output frequency is set to 2.5 GHz, the tolerance is ±10 kHz. If the output frequency of a secondary frequency conversion unit deviates from this range, the signal will be difficult for the mobile terminal to receive correctly or may interfere with other base station signals.
[0028] The output RF signal power must be maintained at a stable level. Assuming the standard power is 40dBm, the allowable fluctuation range is ±0.3dB. If the power is too high, it may interfere with other communication devices; if the power is too low, the signal coverage range will be reduced.
[0029] Signal purity includes indicators such as spurious radiation and harmonic distortion. Excessive spurious radiation can interfere with adjacent frequency band signals, while excessive harmonic distortion can degrade the signal quality. The first frequency conversion unit can compare the collected actual operating parameters with pre-set standard parameters. If the parameter deviation of a second frequency conversion unit exceeds the set threshold, it can be determined that its operating status is abnormal.
[0030] S102: Sending a frequency conversion control instruction to a target control unit and / or sending an alarm instruction to an alarm unit based on the operating state of the second frequency conversion unit;
[0031] Any second frequency conversion unit corresponds to a control unit. The target control unit is the control unit corresponding to any second frequency conversion unit that meets the target conditions. The target conditions are used to judge the target deviation between the operating parameters of the second frequency conversion unit and the standard operating parameters. The frequency conversion control instruction is used to control the target control unit to switch the target signal transmission channel. The alarm instruction is used to issue an alarm indication to the second frequency conversion unit that meets the target conditions.
[0032] In this embodiment, when it is determined that the deviation between the operating parameters of a second frequency conversion unit and the standard parameters meets the target conditions, the first frequency conversion unit can determine the control unit corresponding to the faulty second frequency conversion unit as the target control unit. The first frequency conversion unit sends a frequency conversion control instruction to the target control unit. The frequency conversion control instruction enables the target control unit to quickly switch the signal originally transmitted through the faulty second frequency conversion unit to the signal transmission channel corresponding to the first frequency conversion unit. In this way, even if a main frequency conversion unit fails, the communication base station can continue to maintain signal transmission through the backup channel, avoiding communication interruption and ensuring the continuity of communication service.
[0033] At the same time, the first frequency conversion unit can send an alarm command to the alarm unit. Upon receiving the command, the alarm unit provides local notifications at the base station by flashing indicators and sounding alarms. It also sends an alarm message to the base station's operation and maintenance management platform, detailing the fault number of the faulty second frequency conversion unit, the fault type (such as excessive frequency deviation), and related operating parameters. This allows operation and maintenance personnel to promptly identify faults and arrange for troubleshooting and repair, thereby improving the reliability and maintenance efficiency of the communication base station's frequency conversion system.
[0034] Exemplary, reference Figure 2The signal processing system of a communication base station features a frequency conversion system. This system includes an upconverter-backup unit as the primary frequency conversion unit, and five primary upconverters, upconverter 1# through upconverter 5#, as the secondary frequency conversion units. The frequency conversion units are connected using a daisy-chain design.
[0035] During normal operation, upconverters 1# through 5# correspond to five independent signal transmission channels, each processing an intermediate frequency (IF) input signal (n=1-5) and converting it to an RF output signal (RF output n#). These units perform the signal frequency conversion required for daily base station communications. The upconverter-standby unit is in standby mode.
[0036] The backup upconverter continuously monitors the operating parameters of the five main upconverters in real time. These parameters include frequency accuracy, power stability, and signal purity. For example, the RF output frequency is set to 2.6 GHz with an allowable error of ±10 kHz, and the output power is set to 35 dBm with an allowable fluctuation of ±0.2 dB. If the output frequency of upconverter #5 deviates from the standard by 15 kHz, the backup upconverter will determine that its operating status is abnormal.
[0037] At this time, the up-converter-standby machine determines that the control unit corresponding to up-converter 5# is the target control unit and sends a frequency conversion control instruction to it. Figure 3 , switching the signal originally transmitted through upconverter 5# to the corresponding channel of the upconverter-backup unit. Simultaneously, the upconverter-backup unit sends an alarm command to the alarm unit. The alarm unit notifies maintenance personnel of the failure of upconverter 5# by flashing an indicator light and sending an alarm message to the operation and maintenance platform, allowing for prompt repair and maintenance to ensure stable operation of base station communications.
[0038] From the above, it can be concluded that this embodiment can accurately judge the operating status of multiple second frequency conversion units by real-time monitoring of their operating parameters, and promptly discover abnormal conditions such as frequency deviation, power instability, and signal impurity. Once a second frequency conversion unit failure meets the target conditions, a frequency conversion control instruction can be quickly sent to the corresponding target control unit to switch the signal transmission channel to the spare first frequency conversion unit to ensure continuous and stable transmission of communication signals, avoid communication interruption, and greatly improve communication reliability. At the same time, sending an alarm instruction to the alarm unit can promptly notify the operation and maintenance personnel of the fault details, facilitate their rapid response, troubleshooting, and repair of the fault, reduce fault handling time, improve system maintenance efficiency, reduce the risk of communication service interruption due to frequency conversion unit failure, and enhance the stability and availability of the entire communication system.
[0039] In one embodiment of the present application, the target condition includes a first condition and a second condition;
[0040] The first condition is that a target deviation between the operating parameter of the second frequency conversion unit and the standard operating parameter is greater than a first deviation threshold and less than a second deviation threshold, and the second deviation threshold is greater than the first deviation threshold;
[0041] The second condition is that the target deviation between the operating parameter of the second frequency conversion unit and the standard operating parameter is greater than a second deviation threshold;
[0042] Sending a frequency conversion control instruction to a target control unit and / or sending an alarm instruction to an alarm unit based on the operating state of the second frequency conversion unit includes:
[0043] In response to the operating state of the second frequency conversion unit satisfying the first condition, an alarm instruction is sent to the target control unit.
[0044] In this embodiment, in order to more accurately evaluate the operating status of the second frequency conversion unit, two target conditions are set, namely, a first condition and a second condition.
[0045] When the target deviation between the operating parameters of the second frequency conversion unit and the standard operating parameters is greater than the first deviation threshold and less than the second deviation threshold, it indicates that the second frequency conversion unit has experienced a certain degree of abnormality, but this abnormality has not yet reached a level that seriously affects the normal operation of the system. If the target deviation between the operating parameters of the second frequency conversion unit and the standard operating parameters is greater than the second deviation threshold, it indicates that the abnormality of the second frequency conversion unit is more serious and poses a significant threat to the stable operation of the entire system.
[0046] When the first frequency conversion unit continuously monitors the operating parameters of the second frequency conversion unit, and compares the parameter deviation with the target condition. If the operating status of any second frequency conversion unit meets the first condition, that is, the deviation is in a specific range, although the second frequency conversion unit can still maintain basic work at this time, there is a potential risk. In order to attract the attention of operation and maintenance personnel and promptly investigate and handle possible faults, the first frequency conversion unit can send an alarm instruction to the target control unit corresponding to the second frequency conversion unit. After receiving the instruction, the alarm unit can issue an alarm in a variety of ways, such as flashing indicator lights, sound prompts, or sending alarm information to the operation and maintenance management system, so that operation and maintenance personnel can promptly understand the abnormal situation of the second frequency conversion unit.
[0047] As can be seen from the above, this embodiment refines the criteria for determining abnormalities in the second frequency conversion unit by setting a first deviation threshold and a second deviation threshold to form the first and second conditions. When the operating parameter deviation meets the first condition, an alarm command is sent. This can promptly alert operations and maintenance personnel when a minor abnormality occurs in the equipment but has not yet seriously affected operation. This facilitates early troubleshooting of potential faults, avoids problems such as communication interruptions caused by worsening faults, provides early warning of faults, and improves the operational stability and reliability of the frequency conversion system.
[0048] In one embodiment of the present application, sending a frequency conversion control instruction to a target control unit and / or sending an alarm instruction to an alarm unit based on the operating state of the second frequency conversion unit further includes:
[0049] In response to the operating state of the second frequency conversion unit satisfying the second condition, a frequency conversion control instruction is sent to the target control unit and an alarm instruction is sent to the alarm unit.
[0050] In this embodiment, when the first frequency conversion unit detects that the target deviation between the operating parameters of a second frequency conversion unit and the standard operating parameters meets the second condition, it indicates that the fault of the second frequency conversion unit is serious and may have a significant impact on the normal operation of the system. In this case, the first frequency conversion unit can simultaneously take two key measures: issuing a frequency conversion control command and issuing an alarm command.
[0051] The first frequency conversion unit sends a frequency conversion control command to the target control unit corresponding to the faulty second frequency conversion unit. Upon receiving the command, the target control unit quickly switches the signal originally transmitted through the faulty second frequency conversion unit to a functioning signal transmission channel, such as the channel corresponding to the backup first frequency conversion unit. This ensures continued stable signal transmission, avoids communication interruptions caused by the faulty second frequency conversion unit, and maintains normal system operation.
[0052] At the same time, the first frequency conversion unit sends an alarm command to the alarm unit. Upon receiving the command, the alarm unit activates the alarm mechanism. In this embodiment, this can notify operations and maintenance personnel by flashing an indicator light, sounding an alarm, or sending detailed alarm information to the base station operation and maintenance management platform. This alarm information can include the faulty second frequency conversion unit ID, the specific fault type (such as excessive frequency deviation or abnormal power), and relevant operating parameters. This allows operations and maintenance personnel to promptly and accurately understand the fault details and quickly arrange for troubleshooting and repair.
[0053] As can be seen above, when the second inverter unit's operating status meets the second condition (i.e., a serious abnormality), it sends an inverter control command to the target control unit, rapidly switching the signal transmission channel to ensure continued stable system operation and avoid communication interruptions. It also sends a command to the alarm unit, promptly notifying operations and maintenance personnel. Based on the alarm information, operations and maintenance personnel can quickly locate the fault, troubleshoot, and repair it, reducing the duration of the fault's impact and comprehensively improving system reliability and operations and maintenance efficiency.
[0054] In one embodiment of the present application, the signal transmitted by each signal transmission channel is respectively provided with a signal transmission level, and the signal transmission level of each signal transmission channel is different;
[0055] The frequency conversion system switching control method further includes: in response to a signal transmission level of a signal transmission channel corresponding to the second frequency conversion unit that meets the first condition being a first target signal transmission level, sending a frequency conversion control instruction to a target control unit and sending an alarm instruction to an alarm unit;
[0056] The first target signal transmission level is the highest signal transmission level.
[0057] In this embodiment, the first frequency conversion unit may first monitor the operating parameters of each second frequency conversion unit and compare them with the standard operating parameters to determine whether the first condition is met. When the first frequency conversion unit detects that the operating status of a second frequency conversion unit meets the first condition, the first frequency conversion unit further determines the signal transmission level of the signal transmission channel corresponding to the second frequency conversion unit.
[0058] In this embodiment, the signal transmission level of each signal transmission channel is different. Assuming there are three second frequency conversion units, the signal transmission levels of the second frequency conversion units may include three transmission levels: "low", "medium" and "high".
[0059] If the signal transmission level of the signal transmission channel is the first target signal transmission level (i.e., a "high" transmission level), it indicates that the signal transmitted by this channel is more important to the entire system, and if a problem occurs with the signal in this transmission channel, it could have a serious impact. In this case, the first frequency conversion unit can take two measures simultaneously.
[0060] On the one hand, a frequency conversion control instruction is sent to the target control unit corresponding to the second frequency conversion unit. After receiving the instruction, the target control unit can switch the signal originally transmitted through the faulty second frequency conversion unit to another normal signal transmission channel, such as the channel corresponding to the backup first frequency conversion unit, to ensure the continuous and stable transmission of high-priority signals and avoid communication interruption.
[0061] On the other hand, the first frequency conversion unit can send an alarm command to the alarm unit. Upon receiving the command, the alarm unit activates the alarm mechanism. In this embodiment, the alarm can notify the operation and maintenance personnel by flashing an indicator light, sounding an alarm, or sending detailed alarm information to the base station operation and maintenance management platform. The alarm information will include the faulty second frequency conversion unit number, the specific fault type, and relevant operating parameters, allowing the operation and maintenance personnel to promptly and accurately understand the fault details and quickly arrange personnel to conduct troubleshooting and repair work.
[0062] In this embodiment, if the signal transmission level of the signal transmission channel corresponding to the second frequency conversion unit that meets the first condition is not the first target signal transmission level, only an alarm instruction may be sent without switching the signal channel until the second condition is met. Because the interruption of low-priority signals has a relatively small impact on the overall system, this can avoid unnecessary signal switching operations, improving system stability and resource utilization efficiency.
[0063] As can be seen from the above, this embodiment prioritizes the stable transmission of high-priority signals based on the signal transmission level. When the second frequency conversion unit, which meets the first condition, corresponds to the highest target signal transmission level, it quickly sends a frequency conversion control command to switch channels to avoid signal interruption, and simultaneously sends a command to the alarm unit to notify operations and maintenance. This minimizes the risk of critical signals being affected, optimizes system resource allocation, prioritizes handling of important signal failures, and improves the reliability and stability of the communication system under complex conditions.
[0064] In one embodiment of the present application, each second frequency conversion unit corresponds to a first deviation threshold and a second deviation threshold;
[0065] The frequency conversion system switching control method further includes determining a first deviation threshold and a second deviation threshold corresponding to each second frequency conversion unit based on the signal transmission level and environment information of each signal transmission channel.
[0066] In this embodiment, different signal transmission levels imply different requirements for signal stability and quality. High-level signals require high transmission stability and accuracy; even minor parameter deviations can cause a significant degradation in signal quality, impacting communication effectiveness. Low-level signals, on the other hand, have a relatively high tolerance for deviations. Furthermore, environmental factors can also affect the operating parameters of the second frequency conversion unit. For example, high temperatures can cause device performance degradation, making operating parameter deviations more likely. Therefore, specific first and second deviation thresholds need to be set for each second frequency conversion unit.
[0067] In this embodiment, for the second frequency conversion unit corresponding to the signal transmission channel with a high signal transmission level, in order to ensure the stable transmission of the high-level signal, this embodiment can set a relatively small first deviation threshold and second deviation threshold. This allows the system to more sensitively capture slight changes in the operating parameters of the unit, and to respond in a timely manner once an abnormality occurs, thereby avoiding the high-level signal from being affected. For example, in the field of satellite communications, for the second frequency conversion unit corresponding to the satellite military communication signal, the first deviation threshold of the frequency parameter is set to ±3kHz, and the second deviation threshold is set to ±6kHz. For the second frequency conversion unit corresponding to the ordinary data transmission signal, the deviation threshold can be appropriately increased to reduce unnecessary alarms and switching operations and improve the utilization efficiency of system resources. For example, the first deviation threshold of its frequency parameter is set to ±8kHz, and the second deviation threshold is set to ±15kH.
[0068] In this embodiment, environmental information under the satellite communication, such as radiation intensity, temperature, plasma density, etc., can be collected in real time. When environmental conditions are relatively harsh, such as strong radiation, high temperature or low temperature, the operating parameters of the second frequency conversion unit are more likely to fluctuate. In this case, this embodiment can appropriately increase the deviation threshold to prevent normal fluctuations caused by environmental factors from being misjudged as abnormalities. For example, when the satellite passes through the radiation belt, the first deviation threshold of the power parameter is adjusted from ±0.2dB to ±0.5dB, and the second deviation threshold is adjusted from ±0.5dB to ±1dB. When environmental conditions are good, this embodiment can appropriately reduce the deviation threshold to improve the monitoring accuracy of the system.
[0069] After determining the first deviation threshold and the second deviation threshold corresponding to each second frequency conversion unit, the first frequency conversion unit can judge the operating status of the second frequency conversion unit according to the determined first deviation threshold and second deviation threshold.
[0070] As can be seen from the above, this embodiment sets a low deviation threshold for the second frequency conversion unit corresponding to high-level signals based on the signal transmission level, ensuring the stability of critical signals; and sets a high threshold for units corresponding to low-level signals to optimize resource utilization. Incorporating environmental information, the threshold is increased in adverse environments to prevent misjudgments, while the threshold is reduced in benign environments to improve accuracy. This achieves dynamic threshold adjustment, ensuring stable and reliable signal transmission.
[0071] In one embodiment of the present application, determining a first deviation threshold and a second deviation threshold corresponding to each second frequency conversion unit based on a signal transmission level and environment information of each signal transmission channel includes:
[0072] determining a first weight corresponding to each second frequency conversion unit based on a signal transmission level of each signal transmission channel;
[0073] determining a second weight corresponding to each second frequency conversion unit based on environmental information of each signal transmission channel;
[0074] The first weight and the second weight are integrated to determine a first deviation threshold and a second deviation threshold corresponding to each second frequency conversion unit.
[0075] In this embodiment, the first weight is determined according to the signal transmission level. Assume that there are three second frequency conversion units in the communication base station scenario, and divide the signal transmission level corresponding to the signal transmission channel of each second frequency conversion unit into three levels: high, medium, and low, with corresponding weights 、 、 , in order to distinguish the importance of signals of different levels.
[0076] Environmental information may include temperature, humidity, electromagnetic interference intensity, etc. This embodiment can convert the influence of each environmental information into corresponding weights through fuzzy logic algorithm. For example, define three fuzzy sets of high, medium and low temperatures, and obtain the weight corresponding to the temperature through fuzzy reasoning. ; Similarly, humidity weight is obtained and electromagnetic interference weight .
[0077] Second weight It can be expressed as:
[0078]
[0079] In this embodiment, the second weight is calculated using a geometric mean. Because different environmental factors interact with each other, the geometric mean comprehensively considers the synergistic effects of these factors, avoiding the excessive influence of any one factor. Unlike simple addition or averaging in existing techniques, this embodiment uses a geometric mean to more comprehensively and reasonably reflect the combined environmental impact.
[0080] Fusion first weight and the second weight Determine the deviation threshold. Let the basic first deviation threshold be , the second deviation threshold is .
[0081] The final first deviation threshold Expressed as:
[0082]
[0083] The second deviation threshold obtained Expressed as:
[0084]
[0085] in, and This represents an empirical coefficient, ranging from 0 to 1, used to adjust the relative importance of signal transmission level and environmental information when determining the deviation threshold. By adjusting these two coefficients, we can flexibly balance the impact of signal importance and environmental factors on the deviation threshold based on actual communication scenarios and needs. This allows us to determine the most appropriate deviation threshold for each secondary frequency conversion unit and accurately determine the operating status of the frequency conversion unit.
[0086] From the above, it can be concluded that this embodiment comprehensively considers the signal transmission level and environmental information and determines the deviation threshold using weight fusion, which can adapt to changes in different communication services and environmental conditions and improve the stability and reliability of the frequency conversion system.
[0087] In one embodiment of the present application, the operating parameter is a current operating parameter of the second frequency conversion unit;
[0088] The frequency conversion system switching control method further includes:
[0089] Predicting operating parameters of the second frequency conversion unit based on a long short-term memory network to obtain predicted operating parameters;
[0090] Based on the comparison between the predicted operating parameters and the standard operating parameters, the predicted deviation is obtained;
[0091] Based on the comparison between the predicted operating parameters and the operating parameters, the actual deviation is obtained;
[0092] The target deviation is calculated based on the predicted deviation and the actual deviation.
[0093] In this embodiment, the historical operating parameters of the second frequency conversion unit (such as frequency, power, and signal purity) can be used as time series data and input into a trained long short-term memory (LSTM) network. The LSTM learns the patterns and regularities in the historical data to predict the future operating parameters of the second frequency conversion unit, generating predicted operating parameters. For example, based on the frequency change trend over the past month, the frequency value at the next moment can be predicted.
[0094] The predicted operating parameters are compared with the pre-set standard operating parameters. The standard operating parameters are the parameter values that the frequency conversion unit should reach during normal operation.
[0095] In this embodiment, the prediction deviation is obtained by calculating the difference between the predicted operating parameters and the standard operating parameters. The prediction deviation can reflect the difference between the future operating state predicted based on historical data and the ideal normal state. For example, if the standard frequency is f s , the predicted frequency is fp , then the prediction deviation is expressed as:
[0096]
[0097] in, Represents the forecast deviation.
[0098] In this embodiment, the difference between the predicted operating parameters and the current actual operating parameters of the second frequency conversion unit is calculated to obtain the actual deviation. The actual deviation represents the difference between the predicted operating state and the current actual operating state. For example, if the current actual frequency is f a , then the actual deviation is expressed as:
[0099]
[0100] in, Indicates the actual deviation.
[0101] The predicted deviation and the actual deviation are combined to obtain the target deviation. The combined calculation of the two deviations allows for a more comprehensive assessment of the operating status of the second frequency conversion unit. On the one hand, the predicted deviation can provide an early warning of potential failure risks; on the other hand, the actual deviation can reflect the degree of deviation between the current operating status and the predicted status, thus avoiding misjudgments due to inaccurate predictions. In this embodiment, the target deviation can be calculated using a weighted average. The target deviation is expressed as:
[0102]
[0103] in, represents the target deviation, 、 Both represent weight coefficients.
[0104] This embodiment can determine the operating status of the second frequency conversion unit by comparing the target deviation with pre-set first and second deviation thresholds. If the target deviation exceeds the corresponding threshold, this embodiment can take appropriate control measures, such as issuing frequency conversion control instructions and alarm instructions, to ensure stable operation of the frequency conversion system.
[0105] As can be seen from the above, this embodiment uses a long-short-term memory network to predict operating parameters, enabling early prediction of the potential status of the second inverter unit. By comparing the predicted operating parameters with the standard and current operating parameters, obtaining the predicted and actual deviations, and then calculating the target deviation, a comprehensive and accurate assessment of the unit's operating status can be achieved. This helps to promptly detect potential faults and proactively implement countermeasures, significantly improving the operational stability and reliability of the inverter system.
