Description

Technical Field

[0001] This invention relates to a repeater frequency converter clock calibration system and method. Background Technology

[0002] In modern communication systems, repeaters are crucial network devices widely used to improve signal coverage and network quality. The core function of a repeater is to receive signals from remote devices and transmit them to the target area through amplification and forwarding. To ensure signal quality and system stability, repeaters rely on precise clock synchronization and frequency calibration. However, with the operation of the equipment and changes in the external environment, clock drift and frequency offset frequently occur, severely impacting system performance.

[0003] In existing repeater systems, frequency offset of remote devices is typically caused by factors such as device hardware performance, temperature fluctuations, and power instability. Frequency offset changes are dynamic, and the amount and trend of offset vary among different devices, leading to frequency synchronization errors during long-term system operation. Current technologies often rely on fixed calibration parameters for frequency offset detection and correction, which lacks flexibility and struggles to adapt to a wide range of frequency offset variations. Therefore, errors caused by frequency offset cannot be corrected in a timely manner, thus affecting the overall performance and signal quality of the repeater system.

[0004] Clock drift refers to the change in the internal clock frequency of a device caused by variations in external factors such as ambient temperature and humidity. This drift phenomenon is particularly important in communication systems because clock accuracy directly affects signal synchronization and data transmission accuracy. In current technologies, clock drift monitoring typically relies on simple temperature sensors and fixed drift models, but these methods cannot detect and compensate for clock drift in real time and accurately. The presence of clock drift can lead to a gradual increase in system synchronization errors, thereby affecting system stability and signal quality.

[0005] Existing calibration methods typically employ direct calibration to address frequency offset and clock drift issues. However, direct calibration often involves complex calculations and adjustments, and in some cases, it may not be effective enough, especially when clock drift is large or frequency deviation is severe. In such cases, traditional calibration methods may take too long or even fail to completely eliminate the deviation. Furthermore, current delay compensation techniques are relatively simple and lack flexibility, making it difficult to precisely adjust according to the actual frequency offset value, thus preventing the system from achieving optimal performance.

[0006] Traditional frequency deviation detection methods typically rely on fixed sampling intervals and historical data for frequency calibration, making it impossible to adjust calibration accuracy in real time as environmental conditions change. Although some systems use historical frequency deviation data for correction, this data often lacks timeliness and specificity, thus failing to effectively address frequency variations during actual operation. This lack of accuracy prevents repeater systems from maintaining consistently high-precision clock synchronization in complex operating environments. Summary of the Invention

[0007] The purpose of this invention is to provide a repeater frequency converter clock calibration system and method that solves technical problems such as frequency offset, clock drift and delay compensation in repeater frequency converter clock systems through modular design and real-time calibration capabilities, and can efficiently and accurately ensure the clock accuracy of the system under varying working environments.

[0008] The technical solution adopted by this invention to solve its technical problem is: A repeater frequency converter clock calibration system includes: Reference frequency offset acquisition module: used to acquire the reference frequency offset range of the remote device when performing initial calibration of the repeater system, and set the initial parameters of the frequency offset calibration experiment according to the range; Frequency offset calibration experiment module: used to determine the reference frequency offset value of remote equipment through frequency offset calibration experiment; Frequency offset period calculation module: Calculates the frequency offset period based on the reference frequency offset value, determines the total number of sampling points based on the preset sampling interval, and further calculates the sampling time interval; Historical frequency offset data acquisition module: used to acquire historical frequency offset data and calculate the frequency offset value by combining the historical frequency offset data with the current sampling time interval; Clock drift detection module: used to detect clock drift caused by changes in ambient temperature, and select direct calibration or delay compensation based on the combined frequency deviation value and the degree of clock drift; Delay compensation module: When delay compensation is selected, a zero-frequency offset reference signal is applied to the remote device based on the reference frequency of the near-end device, the actual frequency offset value of the remote device is collected, the actual frequency offset value is converted into a time delay amount, and clock calibration is completed based on the time delay amount.

[0009] Furthermore, the reference frequency offset acquisition module includes a frequency offset range analysis unit, which can obtain the frequency offset range of the remote device during the initialization phase and dynamically adjust the parameters of the frequency offset calibration experiment.

[0010] Furthermore, the frequency offset calibration experimental module measures the frequency offset by using multiple experimental iterations based on the reference frequency offset value of the remote device, ensuring the accuracy of the frequency offset.

[0011] Furthermore, it also includes: The calibration result feedback module is used to generate a calibration report based on the calibration results and to adjust the system accordingly to ensure calibration accuracy.

[0012] Furthermore, the frequency offset period calculation module also includes a sampling time optimization unit, which is used to optimize the sampling time interval based on the frequency offset period and the number of sampling points to improve calibration efficiency.

[0013] Furthermore, the clock drift detection module further includes a temperature compensation unit for dynamically compensating for clock drift under high or low temperature environments.

[0014] Another technical problem to be solved by the present invention is to provide a method for calibrating a frequency converter clock in a repeater, comprising the following steps: When performing initial calibration on the repeater system, the reference frequency offset range of the remote equipment is obtained, and the initial parameters of the frequency offset calibration experiment are set according to this range. The reference frequency offset value of the remote device was determined through a frequency offset calibration experiment. The frequency offset period is calculated based on the reference frequency offset value, and the total number of sampling points is determined according to the preset sampling interval. The sampling time interval is then calculated. Acquire historical frequency offset data, and calculate the frequency offset value by combining the historical frequency offset data with the current sampling time interval; Detect clock drift caused by changes in ambient temperature, combine frequency deviation value with the degree of clock drift, and choose direct calibration or delay compensation; When selecting delay compensation, the reference frequency of the near-end device is used as a reference, a reference signal with zero frequency offset is applied to the far-end device, the actual frequency offset value of the far-end device is collected, the actual frequency offset value is converted into a time delay, and clock calibration is completed based on the time delay.

[0015] The step of obtaining the reference frequency offset range of the remote device further includes real-time dynamic monitoring of the frequency offset range of the remote device and adjusting the initial parameters of the frequency offset calibration experiment.

[0016] Furthermore, the frequency offset calibration experiment step further includes conducting multiple rounds of experiments on the remote device to acquire multiple frequency offset data, and calculating the final reference frequency offset value through data fitting; the step of acquiring historical frequency offset data and calculating the frequency offset value further includes acquiring historical frequency offset data from the storage of the remote device, and calculating the frequency offset value using a weighted average algorithm in combination with the current sampling time interval; the step of detecting clock drift further includes collecting real-time temperature data using an ambient temperature sensor, analyzing the trend of clock drift in combination with historical frequency offset data, and making dynamic adjustments; the step of selecting delay compensation further includes applying a zero frequency offset signal to the remote device, and calculating a specific delay compensation value based on the relationship between the acquired frequency offset data and a preset time delay; the delay compensation step also includes combining the actual frequency offset value of the remote device with the time delay, converting the time delay into frequency offset compensation, and completing clock calibration.

[0017] Another technical problem to be solved by the present invention is to provide an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein when the processor executes the program, it implements the repeater frequency conversion clock calibration method as described above.

[0018] Another technical problem to be solved by the present invention is to provide a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the repeater frequency conversion clock calibration method as described above.

[0019] Compared with the prior art, the beneficial effects of the present invention are: Frequency drift is unavoidable in repeater systems because the frequency of remote equipment is affected by various factors (such as equipment aging, temperature changes, and power fluctuations). Traditional calibration methods cannot address these drifts in real time, and the calibration process for frequency drift is complex. This system, through a reference frequency drift acquisition module and a frequency drift calibration experiment module, can accurately obtain the frequency drift range of remote equipment and dynamically correct the frequency during experiments to ensure the stable operation of the repeater system. Clock drift is a problem with the accuracy of the device's clock caused by environmental factors (such as temperature changes), which usually leads to the accumulation of clock errors and affects the operation of the entire system. This solution, through a clock drift detection module, can monitor and detect clock drift problems caused by environmental changes in real time. Combining historical frequency drift data and temperature changes, it selects whether to perform direct calibration or delay compensation to ensure that the system can adapt to changes in the external environment and avoid the accumulation of drift errors.

[0020] When the frequency offset error of the remote device is large, direct calibration may result in excessive time or error, thus affecting system performance. To address this issue, a delay compensation module is designed into the system. When clock drift is detected, causing a large frequency offset error, the delay compensation module can convert the actual frequency offset value into a time delay using the reference signal from the near-end device, thereby achieving clock calibration and avoiding the complexity and uncertainty of direct calibration. Traditional frequency offset calibration methods often lack accuracy or cannot fully adapt to frequency offset changes caused by different environmental factors. This solution improves the accuracy of frequency offset calibration and reduces signal loss or error caused by inaccurate calibration by accurately calculating the sampling time interval, combining historical frequency offset data, and working in conjunction with the real-time detection module. The repeater system needs to be able to cope with different working environments and equipment conditions. By integrating historical frequency offset data, the current sampling interval, and clock drift information, the system can adaptively adjust calibration parameters, ensuring that the system can automatically optimize the calibration process under different conditions, thus improving the system's stability and flexibility.

[0022] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of the invention. The invention is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the invention will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the invention.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] Example See Figure 1 As shown, a repeater frequency converter clock calibration system includes: Reference frequency offset acquisition module: used to acquire the reference frequency offset range of the remote device when performing initial calibration of the repeater system, and set the initial parameters of the frequency offset calibration experiment according to the range; Frequency offset calibration experiment module: used to determine the reference frequency offset value of remote equipment through frequency offset calibration experiment; Frequency offset period calculation module: Calculates the frequency offset period based on the reference frequency offset value, determines the total number of sampling points based on the preset sampling interval, and further calculates the sampling time interval; Historical frequency offset data acquisition module: used to acquire historical frequency offset data and calculate the frequency offset value by combining the historical frequency offset data with the current sampling time interval; Clock drift detection module: used to detect clock drift caused by changes in ambient temperature, and select direct calibration or delay compensation based on the combined frequency deviation value and the degree of clock drift; Delay compensation module: When delay compensation is selected, a zero-frequency offset reference signal is applied to the remote device based on the reference frequency of the near-end device, the actual frequency offset value of the remote device is collected, the actual frequency offset value is converted into a time delay amount, and clock calibration is completed based on the time delay amount.

[0025] By combining the reference frequency offset acquisition module and the frequency offset calibration experiment module, the system can accurately acquire the reference frequency offset range of the remote device during initialization and set the initial parameters of the calibration experiment based on this range. In this way, the system can dynamically calibrate the frequency offset for different devices and environments, ensuring that the remote device maintains consistency with the reference frequency throughout operation. This method avoids the limitations of traditional static calibration, significantly improves frequency synchronization accuracy, and reduces communication errors caused by frequency offset.

[0026] Clock drift is typically affected by factors such as temperature variations and equipment aging. The clock drift detection module allows the system to monitor clock drift in real time and make flexible adjustments based on frequency deviation values. When clock drift is detected, the system can automatically select either direct calibration or delay compensation based on the actual situation, effectively reducing clock synchronization errors caused by environmental factors. The module's adaptive and intelligent processing capabilities enable the system to operate stably in various complex environments, improving the reliability and continuous stability of the repeater system.

[0027] When the system detects the need for delay compensation, the delay compensation module applies a compensation signal through a zero-frequency offset reference signal. This converts the frequency offset value of the remote device into a time delay, and the clock is precisely adjusted based on this delay. This design effectively solves the response lag problem of traditional methods under high-frequency offset conditions. Through precise calibration between the near-end and remote devices, the delay compensation mechanism not only improves the system's accuracy but also effectively reduces the delay caused by clock drift and frequency offset, ensuring the real-time performance and reliability of signal transmission. The reference frequency offset acquisition module includes a frequency offset range analysis unit, which can obtain the frequency offset range of the remote device during the initialization phase and dynamically adjust the parameters of the frequency offset calibration experiment. The frequency offset calibration experiment module performs frequency offset measurement by using multiple experimental iterations based on the reference frequency offset value of the remote device to ensure the accuracy of the frequency offset.

[0028] The frequency offset range analysis unit in the reference frequency offset acquisition module can acquire the frequency offset range of remote devices in real time during the initialization phase and dynamically adjust the parameters of the frequency offset calibration experiment. This allows the system to automatically adjust parameters according to the specific conditions of different devices without manual intervention. As network conditions or device performance change, the system can adaptively perform frequency calibration, ensuring that the synchronization accuracy between devices remains at a high level even in different usage scenarios or environments.

[0029] Through multiple iterative experiments, the frequency offset calibration module can repeatedly measure the frequency offset value of remote equipment, thereby reducing the impact of random errors or interference. Each iteration allows for a more precise measurement of the equipment's frequency offset, ensuring that the accuracy of the frequency offset reaches the ideal level. This process of multiple measurements improves calibration accuracy, reduces errors that may arise from a single measurement, and ensures the long-term stability of the equipment.

[0030] Employing multiple iterative calibration experiments not only provides more accurate frequency offset calibration but also ensures the system's robustness under various conditions. Especially when remote equipment experiences environmental fluctuations or other instabilities, repeated calibration allows the system to gradually adjust to its optimal state, thus better coping with complex and dynamic communication environments. This approach not only enhances the system's adaptability but also improves the accuracy and stability of the equipment during long-term operation.

[0031] It also includes: a calibration result feedback module, used to generate a calibration report based on the calibration result and to adjust the system accordingly to ensure calibration accuracy; the frequency offset period calculation module also includes a sampling time optimization unit, used to optimize the sampling time interval based on the frequency offset period and the number of sampling points to improve calibration efficiency; the clock drift detection module further includes a temperature compensation unit, used to dynamically compensate for clock drift in high or low temperature environments.

[0032] The calibration result feedback module, as one of the core functions of the system, comprehensively collects and analyzes all data generated during the calibration process and generates detailed calibration reports accordingly. This module not only records key parameters and results during calibration but also continuously optimizes the system through an intelligent feedback adjustment mechanism. This closed-loop feedback mechanism ensures that after each calibration task, the system can self-adjust and improve based on actual operational feedback. Through this dynamic optimization process, the system can continuously improve calibration accuracy and long-term stability. Particularly noteworthy is the module's support for real-time adjustment, enabling the system to quickly respond to environmental changes or equipment status fluctuations, thereby maintaining optimal calibration accuracy under various operating conditions and maximizing the reliability of measurement results.

[0033] The sampling time optimization unit employs an advanced algorithm design that intelligently calculates the optimal sampling time interval based on real-time monitored frequency offset period characteristics and sampling point requirements. This dynamic optimization strategy effectively avoids the resource waste that may result from traditional fixed sampling intervals and significantly reduces invalid sampling time. By precisely controlling the sampling timing, this unit ensures that the calibration process can acquire a sufficient quantity of reliable sampling data in the shortest possible time. This optimized design plays a crucial role in improving overall calibration efficiency, especially when facing large-scale equipment array calibration or high-frequency continuous calibration tasks. The implementation of this unit enables the system to significantly improve the overall efficiency of calibration operations while ensuring data accuracy.

[0034] The temperature compensation unit employs multi-sensor fusion technology to monitor ambient temperature changes in real time and provide precise dynamic compensation for clock drift. This unit integrates a high-precision temperature sensor and advanced compensation algorithms to accurately capture the impact of temperature fluctuations on clock stability. When the system operates in extreme environments such as high or low temperatures, this unit automatically initiates the compensation program to correct temperature-induced clock deviations in real time. This intelligent compensation mechanism ensures that the device maintains accurate clock synchronization performance under various harsh environmental conditions. Through continuous temperature monitoring and dynamic compensation, this unit significantly improves the system's reliability and operational stability under extreme temperature conditions, giving the device stronger environmental adaptability and robustness.

[0035] A method for calibrating a frequency converter clock in a repeater includes the following steps: When performing initial calibration on the repeater system, the reference frequency offset range of the remote equipment is obtained, and the initial parameters of the frequency offset calibration experiment are set according to this range. The reference frequency offset value of the remote device was determined through a frequency offset calibration experiment. The frequency offset period is calculated based on the reference frequency offset value, and the total number of sampling points is determined according to the preset sampling interval. The sampling time interval is then calculated. Acquire historical frequency offset data, and calculate the frequency offset value by combining the historical frequency offset data with the current sampling time interval; Detect clock drift caused by changes in ambient temperature, combine frequency deviation value with the degree of clock drift, and choose direct calibration or delay compensation; When selecting delay compensation, the reference frequency of the near-end device is used as a reference, a reference signal with zero frequency offset is applied to the far-end device, the actual frequency offset value of the far-end device is collected, the actual frequency offset value is converted into a time delay, and clock calibration is completed based on the time delay.

[0036] The step of obtaining the reference frequency offset range of the remote device further includes real-time dynamic monitoring of the frequency offset range of the remote device and adjusting the initial parameters of the frequency offset calibration experiment.

[0037] By dynamically monitoring the frequency offset range of remote devices in real time, the initial parameters of the frequency offset calibration experiment can be adjusted accordingly. This flexible adjustment allows the system to calibrate based on the actual conditions of the remote devices, thereby improving calibration accuracy and adapting to changes in equipment or network conditions. In this way, calibration requirements for different environments or devices can be precisely met, effectively avoiding calibration errors that may result from fixed parameters in traditional methods.

[0038] Detecting and compensating for clock drift caused by changes in ambient temperature effectively addresses the impact of temperature fluctuations on clock stability. Since temperature variations cause clock frequency drift, this compensation mechanism dynamically adjusts the compensation strategy (direct calibration or delay compensation) to address drift under different temperature conditions, ensuring that the system's clock accuracy remains unaffected even in harsh environments, thus improving system stability and reliability.

[0039] By calculating the frequency offset value based on historical frequency offset data and the current sampling time interval, the system can more accurately predict and compensate for frequency offset changes in remote devices. This not only improves the efficiency of the calibration process but also optimizes the sampling process based on historical data, avoiding invalid repeated measurements, thereby saving time and improving overall performance. Furthermore, when selecting delay compensation, the system can flexibly choose to use the reference frequency of the near-end device as a reference for calibration, further improving the accuracy and efficiency of calibration.

[0040] The frequency offset calibration experiment step further includes conducting multiple rounds of experiments on the remote device to acquire multiple frequency offset data, and calculating the final reference frequency offset value through data fitting; the step of acquiring historical frequency offset data and calculating the frequency offset value further includes acquiring historical frequency offset data from the storage of the remote device, and calculating the frequency offset value using a weighted average algorithm in combination with the current sampling time interval; the step of detecting clock drift further includes collecting real-time temperature data using an ambient temperature sensor, analyzing the trend of clock drift in combination with historical frequency offset data, and making dynamic adjustments; the step of selecting delay compensation further includes applying a zero frequency offset signal to the remote device, and calculating a specific delay compensation value based on the relationship between the acquired frequency offset data and a preset time delay; the delay compensation step also includes combining the actual frequency offset value of the remote device with the time delay, converting the time delay into frequency offset compensation, and completing clock calibration.

[0041] By acquiring multiple frequency offset data points through multiple rounds of experiments and employing data fitting to calculate the final reference frequency offset value, errors from a single experiment can be effectively eliminated, improving the accuracy of the final calculation. Multiple rounds of experiments allow for a more comprehensive evaluation of the frequency offset fluctuations, ensuring that the obtained reference frequency value is more representative and stable, thereby making the calibration process more precise.

[0042] By collecting real-time temperature data using an ambient temperature sensor and analyzing historical frequency offset data to determine clock drift trends, dynamic adjustments can be made under different environmental conditions. The impact of temperature changes on the clock is significant; this method allows for real-time monitoring and adaptation to environmental changes, avoiding clock drift issues that can occur with fixed parameters, and further improving system stability and reliability. The dynamic adjustment capability enables the system to maintain high clock accuracy even in environments with significant temperature variations.

[0043] In the delay compensation step, by applying a zero-frequency offset signal to the remote device and collecting frequency offset data, which is then correlated with a preset time delay, the specific delay compensation value can be accurately calculated. This method not only accurately compensates for clock deviations but also combines the actual frequency offset value with the time delay, effectively converting it into frequency offset compensation, thereby ensuring the accurate completion of the calibration process. Optimizing this process can significantly improve the clock synchronization accuracy of the system under delayed conditions and reduce the impact of clock errors on the overall system performance.
