Description

Technical Field

[0001] The present invention belongs to the technical field of radio frequency direct acquisition, and in particular relates to a radio frequency direct acquisition system and method based on broadband reception. Background Art

[0002] With the rapid development of wireless communication technology, the reception and processing of radio frequency signals play a vital role in communication systems. Especially in broadband communication systems, the bandwidth of radio frequency signals is wide, the frequency fluctuation is large, and the signal strength difference is obvious, which brings great challenges to the stable reception and processing of signals. Traditional radio frequency signal reception methods usually use intermediate frequency conversion and multi-stage filtering technology. Although this method can effectively process the signal, it often causes signal distortion during the processing process, increases the complexity of signal processing, and reduces the real-time performance of the system.

[0003] In addition, the intermediate frequency conversion and filtering steps in the traditional method require relatively complex hardware equipment and a long processing time, which creates a major obstacle to efficient and real-time signal reception and processing. Especially in a high-dynamic environment, signal frequency fluctuations, bandwidth changes, and signal-to-noise ratio fluctuations may lead to a decrease in signal reception quality, thereby affecting communication quality and data reliability. Therefore, how to accurately receive and process broadband RF signals without adding too much hardware burden has become an important research topic in RF reception technology.

[0004] In the existing technology, although there are some optimization methods for RF signal reception, most of them still rely on traditional filtering and frequency conversion technology, which cannot fully cope with the changes of broadband signals in frequency, bandwidth, etc. Especially in complex wireless environments, the quality of signals may change significantly due to environmental factors, equipment failure or interference, and it is difficult for existing technologies to respond to these changes in real time and accurately.

Obtain corresponding compensation information according to the signal reception result, obtain a corresponding RF direct acquisition strategy according to the compensation information and the signal reception information, and receive a broadband RF signal according to the corresponding RF direct acquisition strategy.

[0099] As in the above steps S1 to S6, the broadband radio frequency signal data to be received is obtained through the acquisition device, and it is determined whether it meets the first preset condition (such as the signal amplitude range, the data volume range, etc.). If the signal data exceeds the preset range, it is marked as excess signal data, and an evaluation period is defined at the same time. During the evaluation period, the frequency data of the broadband radio frequency signal is extracted to obtain the frequency fluctuation information.

[0100] In a preferred embodiment, the steps of obtaining the broadband radio frequency signal data to be received, determining whether the broadband radio frequency signal data meets the first preset condition, and if not, marking the excess signal data, and constructing the evaluation period include:

[0101] S101, obtaining broadband radio frequency signal data to be received;

[0102] S102, acquiring corresponding broadband radio frequency signal data volume according to the broadband radio frequency signal data;

[0103] S103, obtaining a corresponding signal data vector according to the broadband radio frequency signal data volume;

[0104] S104, obtaining a signal data threshold;

[0105] S105, determining whether the signal data vector exceeds the signal data threshold;

[0106] If the signal data vector exceeds the signal data threshold, it is determined that the data volume of the broadband radio frequency signal data exceeds the standard and is marked as excess signal data;

[0107] S106, obtaining a time node marked as excess signal data, and marking it as the end time;

[0108] S107, obtaining a corresponding evaluation duration according to the signal data vector;

[0109] S108, obtaining the start time according to the evaluation duration and the end time;

[0110] S109: Obtain an evaluation period according to the start time and the end time.

[0111] As in the above steps S101 to S109, the broadband RF signal data to be received is collected by the receiving device to obtain its data volume (such as data packet size, number of sampling points, etc.), and a signal data vector is constructed according to the signal data volume, and a signal data threshold is set. The threshold is used to determine whether the signal data is excessive. The setting of the threshold is usually based on design specifications or empirical data, representing the maximum value of the signal data under normal circumstances. The signal data vector is compared with the preset signal data threshold. If the value of the signal data vector exceeds the threshold, it means that the signal data volume exceeds the standard, which may cause processing difficulties or signal distortion in the receiving system, and it is determined to be excess signal data, and is marked as excess signal data. The time node when the excess signal data appears is obtained, and it is marked as the result. Beam time, according to the characteristics of the signal data vector, an evaluation duration is obtained. The evaluation duration refers to the time period from the occurrence of excess signal data to the end time, which is used to evaluate the continuity and impact of the signal. The evaluation duration is pre-set according to the design specifications or empirical data. According to the evaluation duration and the end time, the start time of the evaluation period is obtained. According to the start time and the end time, the evaluation period is finally determined. The evaluation period is a time window that includes the occurrence process of excess signal data. It can accurately identify excess signal data and avoid reception quality problems caused by signal overload. It can adapt to different signal environments and changes, especially in the reception process of broadband RF signals. It can flexibly respond to different data volumes and signal qualities to improve the robustness of the system.

[0112] In a preferred embodiment, the step of obtaining signal frequency data of a broadband radio frequency signal within an evaluation period and obtaining corresponding frequency fluctuation information according to the signal frequency data includes:

[0113] S201, obtaining signal frequency data of a broadband radio frequency signal within an evaluation period;

[0114] S202, acquiring a plurality of corresponding signal frequency vectors according to the signal frequency data;

[0115] S203: Obtain corresponding frequency compensation values ​​according to multiple signal frequency vectors, and mark them as frequency fluctuation information.

[0116] As in the above steps S201 to S203, the signal frequency data of the broadband RF signal within the evaluation period is obtained by the acquisition device, and the obtained signal frequency data is converted into multiple signal frequency vectors. According to the multiple signal frequency vectors, the frequency compensation value is calculated and marked as frequency fluctuation information. The calculation formula of the frequency compensation value is: Where, f represents the frequency compensation value, i represents the number of multiple signal frequency vectors, i = 1, 2, 3...n, H i It is represented as the i-th signal frequency vector. By obtaining the frequency fluctuation information, the stability of the signal can be effectively evaluated.

[0117] In a preferred embodiment, the step of obtaining bandwidth data of a broadband radio frequency signal within an evaluation period and obtaining corresponding bandwidth anomaly information according to the bandwidth data includes:

[0118] S301, obtaining bandwidth data of a broadband radio frequency signal within an evaluation period;

[0119] S302, acquiring a plurality of corresponding bandwidth vectors according to the bandwidth data;

[0120] S303, acquiring corresponding bandwidth compensation values ​​according to multiple bandwidth vectors;

[0121] S304, obtaining a bandwidth anomaly assessment interval;

[0122] S305, determining whether the bandwidth compensation value is within the bandwidth anomaly assessment interval;

[0123] If the bandwidth compensation value is within the bandwidth anomaly assessment interval, the bandwidth anomaly information is determined to be stable;

[0124] If the bandwidth compensation value is not within the bandwidth anomaly assessment interval and is greater than the upper limit of the bandwidth anomaly assessment interval, the bandwidth anomaly information is determined to be high anomaly;

[0125] If the bandwidth compensation value is not within the bandwidth anomaly assessment interval and is less than the lower limit of the bandwidth anomaly assessment interval, the bandwidth anomaly information is determined to be a low anomaly.

[0126] As in the above steps S301 to S305, the bandwidth data of the broadband radio frequency signal within the evaluation period is obtained by the acquisition device, the obtained bandwidth data is converted into multiple bandwidth vectors, and the bandwidth compensation value is calculated based on the analysis of the multiple bandwidth vectors. The calculation formula of the bandwidth compensation value is: Where Y represents the bandwidth compensation value, r represents the number of multiple bandwidth vectors, r = 1, 2, 3...u, P rIt is represented as the rth bandwidth vector. The bandwidth anomaly evaluation interval is set. This interval is usually determined based on system design requirements or empirical data. It represents the fluctuation interval of the signal bandwidth within the normal range. The bandwidth anomaly evaluation interval has an upper limit and a lower limit, which are used to determine whether the signal bandwidth exceeds the normal range. The bandwidth compensation value is compared with the preset bandwidth anomaly evaluation interval to determine whether the bandwidth compensation value falls within the interval. If the bandwidth compensation value is within the bandwidth anomaly evaluation interval, the bandwidth anomaly information is determined to be "stable", indicating that the signal bandwidth change is within the normal range. If the bandwidth compensation value is not within the bandwidth anomaly evaluation interval and is greater than the upper limit of the evaluation interval, it is determined to be "high anomaly", indicating that the signal bandwidth has fluctuated too much, which may affect the signal quality. If the bandwidth compensation value is not within the bandwidth anomaly evaluation interval and is less than the lower limit of the evaluation interval, it is determined to be "low anomaly", indicating that the signal bandwidth fluctuation is too small, which may lead to insufficient signal transmission capacity. The abnormal fluctuation of the signal bandwidth can be accurately identified. Bandwidth anomaly may cause signal quality degradation or communication failure. Timely detection and classification of anomalies helps prevent system performance degradation.

[0127] In a preferred embodiment, the step of obtaining signal-to-noise ratio data of a broadband radio frequency signal within an evaluation period and obtaining signal strength information according to the signal-to-noise ratio data includes:

[0128] S401, obtaining signal-to-noise ratio data of a broadband radio frequency signal within an evaluation period;

[0129] S402, acquiring a plurality of corresponding signal-to-noise vectors according to the signal-to-noise ratio data;

[0130] S403, obtaining corresponding signal-noise compensation values ​​according to multiple signal-noise vectors;

[0131] S404, obtaining a signal-to-noise table, wherein the signal-to-noise table includes a plurality of signal-to-noise compensation intervals and a signal strength value corresponding to each signal-to-noise compensation interval;

[0132] S405, obtaining a target signal-to-noise compensation interval according to the signal fluctuation value;

[0133] S406: Obtain a signal strength value from a signal-to-noise table according to the target signal-to-noise compensation interval, and mark it as signal strength information.

[0134] As in the above steps S401 to S406, the signal-to-noise ratio data of the broadband radio frequency signal in the evaluation period is obtained by the acquisition device, the obtained signal-to-noise ratio data is converted into multiple signal-to-noise vectors, and the signal-to-noise compensation value is calculated according to the multiple signal-to-noise vectors. The calculation formula of the signal-to-noise compensation value is: Where X represents the signal-noise compensation value, t represents the number of multiple signal-noise vectors, t = 1, 2, 3 ... m, Z tIt is represented as the t-th operating state value. The signal-to-noise table is a preset data table, which contains multiple signal-to-noise compensation intervals and the signal strength value corresponding to each interval. The signal-to-noise table defines different levels of signal strength according to different signal-to-noise compensation value intervals. The calculated signal-to-noise compensation value is matched with the interval in the signal-to-noise table to determine the target signal-to-noise compensation interval where the signal fluctuation value is located. According to the target signal-to-noise compensation interval, the corresponding signal strength value is extracted from the signal-to-noise table and marked as signal strength information, which can accurately identify the signal strength of the current broadband RF signal data.

[0135] In a preferred embodiment, signal reception information is obtained according to frequency fluctuation information, bandwidth anomaly information, and signal strength information, and a signal reception result is obtained according to the signal reception information, wherein the signal reception result includes the steps of normal signal reception and abnormal signal reception, including:

[0136] S501, obtaining a corresponding frequency compensation value according to frequency fluctuation information;

[0137] S502, obtaining a corresponding bandwidth compensation value according to bandwidth anomaly information;

[0138] S503, obtaining a corresponding signal-to-noise compensation value according to the signal strength information;

[0139] S504, obtaining a signal reception value according to the frequency compensation value, the bandwidth compensation value, and the signal-to-noise compensation value, and marking it as signal reception information;

[0140] S505, obtaining a signal reception threshold;

[0141] S506, determining whether the signal reception value exceeds the signal reception threshold;

[0142] If the signal reception value does not exceed the signal reception threshold, it is determined that the signal reception result of the broadband radio frequency signal is normal signal reception;

[0143] If the signal reception value exceeds the signal reception threshold, it is determined that the signal reception result of the broadband radio frequency signal is abnormal signal reception.

[0144] As in the above steps S501 to S506, the frequency compensation value is extracted through the frequency fluctuation information, the bandwidth compensation value can be extracted through the bandwidth anomaly information, and the signal-to-noise compensation value is extracted through the signal strength information. The frequency compensation value, the bandwidth compensation value and the signal-to-noise compensation value are combined to comprehensively evaluate the overall quality of signal reception, and the signal reception value is calculated and marked as signal reception information. The value represents the comprehensive reception quality of the signal. The calculation formula of the signal reception value is S=f*Y*X, where S represents the signal reception value, f represents the frequency compensation value, Y represents the bandwidth compensation value, and X represents the signal-to-noise compensation value. The signal reception threshold is a preset standard for distinguishing normal signal reception from abnormal signal reception. The threshold is usually set based on historical data, system requirements or empirical rules. The calculated signal reception value is compared with the signal reception threshold. If the signal reception value exceeds the threshold, it indicates that the signal quality is abnormal, and there may be interference, attenuation or other problems. If the signal reception value does not exceed the threshold, it indicates that the signal quality is normal and meets the system requirements. The signal reception quality can be evaluated more comprehensively and accurately to ensure the accuracy of the signal reception result.

[0145] Embodiment 1 is a method for obtaining a radio frequency direct acquisition strategy when a signal reception result enables normal signal reception. Specifically, corresponding compensation information is obtained according to the signal reception result, and a corresponding radio frequency direct acquisition strategy is obtained according to the compensation information and the signal reception information. The steps of receiving a broadband radio frequency signal according to the corresponding radio frequency direct acquisition strategy include:

[0146] S601, when the signal reception result is normal signal reception, the environmental factor data within the evaluation period is obtained;

[0147] S602, acquiring corresponding multiple environmental vectors according to the environmental factor data;

[0148] S603, acquiring a corresponding signal reception value according to the signal reception information;

[0149] S604, obtaining a radio frequency reception value according to a plurality of environment vectors and a signal reception value;

[0150] S605: Obtain a normal direct purchase table, where the normal direct purchase table includes multiple radio frequency receiving intervals and a radio frequency direct purchase strategy corresponding to each radio frequency receiving interval;

[0151] S606, obtaining a target radio frequency receiving interval according to the radio frequency receiving value;

[0152] S607, obtaining a radio frequency direct purchase strategy from a normal direct purchase table according to the target radio frequency receiving interval;

[0153] S608: Receive a broadband radio frequency signal according to a radio frequency direct acquisition strategy.

[0154] As in the above steps S601 to S608, when the signal reception result is normal signal reception, it indicates that the signal quality meets expectations. At this time, it is necessary to further consider the impact of the external environment on signal reception. Therefore, firstly, the environmental factor data within the evaluation period is obtained, such as temperature, humidity, weather, interference source, etc. These factors may affect the propagation and reception of RF signals. The environmental factor data usually contains multiple variables, such as temperature, humidity, etc. By analyzing these data, they can be converted into multiple environmental vectors. According to the previously obtained signal reception information, the signal reception value is obtained, and the environmental vector and the signal reception value are combined to comprehensively evaluate the RF reception value. The calculation formula of the RF reception value is: In the formula, C normal It represents the RF receiving value when the receiving result is normal signal reception, S represents the signal receiving value, q represents the number of multiple environment vectors, q = 1, 2, 3...g, J g It is represented as the g-th environmental vector. The normal direct acquisition table contains multiple RF receiving intervals, each of which corresponds to an RF direct acquisition strategy. The RF direct acquisition strategy is the optimal receiving strategy formulated for factors such as signal strength and frequency in different receiving intervals. The table provides the best RF direct acquisition solution under different signal reception values. According to the calculated RF reception value, the RF receiving interval where the value is located is determined. The RF receiving interval is divided according to the range of RF reception values. Different intervals correspond to different receiving strategies. The RF direct acquisition strategy corresponding to the target RF receiving interval is found from the normal direct acquisition table. Each RF receiving interval has an optimal RF direct acquisition strategy, which may include adjusting the receiving frequency, enhancing the signal strength, adjusting the sampling rate, etc. According to the selected RF direct acquisition strategy, corresponding operations are performed to receive broadband RF signals, which may include adjusting the receiving parameters of the equipment, optimizing the signal processing process, etc., to ensure efficient reception and processing of the signal. The optimal RF direct acquisition strategy can be selected under different environmental conditions to maximize the signal reception quality. This optimization can ensure stable signal reception in various environments, and can dynamically adjust the receiving strategy according to different environmental factors and signal reception conditions to enhance the adaptability to different interference sources and environmental changes.

[0155] Embodiment 2 is a method for obtaining a radio frequency direct acquisition strategy when a signal reception result causes an abnormal signal to be received. Specifically, corresponding compensation information is obtained according to the signal reception result, and a corresponding radio frequency direct acquisition strategy is obtained according to the compensation information and the signal reception information. The steps of receiving a broadband radio frequency signal according to the corresponding radio frequency direct acquisition strategy include:

[0156] Step 601, when the signal reception result is abnormal signal reception, the environmental factor data and signal impedance data within the evaluation period are obtained;

[0157] Step 602, obtaining corresponding multiple environmental vectors according to the environmental factor data;

[0158] Step 603, obtaining corresponding multiple signal impedance vectors according to the signal impedance data;

[0159] Step 604, obtaining a corresponding signal reception value according to the signal reception information;

[0160] Step 605, obtaining a radio frequency reception value according to a plurality of environment vectors, a plurality of signal impedance vectors and a signal reception value;

[0161] Step 606, obtaining an abnormal direct purchase table, wherein the abnormal direct purchase table includes multiple radio frequency receiving intervals and a radio frequency direct purchase strategy corresponding to each radio frequency receiving interval;

[0162] Step 607, obtaining the target radio frequency receiving interval according to the radio frequency receiving value;

[0163] Step 608, obtaining the RF direct purchase strategy from the abnormal direct purchase table according to the target RF receiving interval;

[0164] Step 609: Receive broadband RF signals according to the RF direct acquisition strategy.

[0165] As in the above steps Step 601 to Step 609, when the signal reception result is abnormal signal reception, it means that the signal quality does not meet expectations, and it is necessary to further evaluate the influence of factors such as the external environment and device impedance on the signal. Therefore, the environmental factor data (such as temperature, humidity, weather conditions, etc.) and signal impedance data (such as the impedance characteristics of the device, the impedance of the transmission path, etc.) during the evaluation period are obtained. These factors may cause changes in signal quality and need to be compensated. The environmental factor data usually contains multiple variables, such as temperature, humidity, air pressure, etc., which are converted into multiple environmental vectors. The signal impedance data reflects the impedance characteristics of the signal during the transmission process. Different signal impedances may cause signal attenuation or distortion. Therefore, it is necessary to obtain multiple signal impedance vectors based on the signal impedance data, and obtain the signal reception value based on the signal reception information. The environmental vector, signal impedance vector and signal reception value are combined to comprehensively evaluate the RF reception value. The calculation formula of the RF reception value is: In the formula, C normal It represents the RF receiving value when the receiving result is normal signal reception, S represents the signal receiving value, q represents the number of multiple environment vectors, q = 1, 2, 3...g, J g It is represented as the g-th environment vector, b is represented as the number of multiple signal impedance vectors, b = 1, 2, 3...d, K bIt is represented as the bth signal impedance vector. The abnormal direct acquisition table contains multiple RF receiving intervals, each of which corresponds to an RF direct acquisition strategy. The RF direct acquisition strategy is the optimal receiving strategy formulated for factors such as signal strength and frequency in different receiving intervals. The table provides the best RF direct acquisition solution under different signal reception values. According to the calculated RF reception value, the RF receiving interval where the value is located is determined. The RF receiving interval is divided according to the range of RF reception values. Different intervals correspond to different receiving strategies. The RF direct acquisition strategy corresponding to the target RF receiving interval is found from the abnormal direct acquisition table. Each RF receiving interval has an optimal RF direct acquisition strategy, which may include adjusting the receiving frequency, enhancing the signal strength, adjusting the sampling rate, etc. According to the selected RF direct acquisition strategy, corresponding operations are performed to receive broadband RF signals, which may include adjusting the receiving parameters of the equipment, optimizing the signal processing process, etc., to ensure efficient reception and processing of the signal, and to compensate when the signal reception is abnormal, thereby improving the signal quality, effectively coping with external interference and equipment problems, ensuring the stability of signal reception, and adjusting the receiving strategy for different signal reception conditions (such as signal attenuation, impedance change, etc.), thereby maximizing the signal reception effect.

[0166] Please refer to the attached Figure 2 As shown, the present invention also provides a RF direct acquisition system based on broadband reception, which is used in the above-mentioned RF direct acquisition method based on broadband reception, including:

[0173] In the above, the signal judgment module obtains the broadband radio frequency signal data to be received, and determines whether it meets the first preset condition. The preset condition may include requirements on signal data volume, signal frequency, bandwidth, strength, etc. If the signal does not meet the conditions, it is marked as excess signal data, and the evaluation period is constructed. The frequency fluctuation module obtains the signal frequency data of the broadband radio frequency signal during the evaluation period, and obtains the frequency fluctuation information. The bandwidth anomaly module is responsible for obtaining the bandwidth data of the broadband radio frequency signal during the evaluation period and identifying the bandwidth anomaly information. The signal strength module obtains the signal-to-noise ratio data of the broadband radio frequency signal during the evaluation period, and obtains the signal strength information by processing the signal-to-noise ratio data. The signal receiving module processes the frequency fluctuation information, the bandwidth anomaly information and the signal strength information. Comprehensively evaluate the signal reception situation and generate signal reception information. Based on the signal reception information, further determine whether the signal reception result is normal, which is divided into normal signal reception and abnormal signal reception. The RF direct acquisition module obtains the corresponding compensation information according to the signal reception result (normal or abnormal), and generates an RF direct acquisition strategy based on the signal reception information. According to the RF direct acquisition strategy, adjust the parameters of the receiving equipment, optimize the reception of broadband RF signals, and ensure that the signal quality is guaranteed at each stage. When the signal is abnormal, it can be identified and compensated in time to avoid signal quality degradation. According to different signal reception results (normal or abnormal), the RF direct acquisition strategy can be automatically adjusted to adapt to different signal conditions to ensure stable signal reception and efficient processing.
