[0046] like Figure 1 As shown, in an embodiment of the present application, a long-distance signal transmission optimization method is provided, including: S100: obtaining a signal to be transmitted, and determining the signal type of the signal to be transmitted; S200: selecting a corresponding signal modulation method according to the signal type to modulate the signal to be transmitted, and obtaining a plurality of modulation signal groups; S300: performing feature analysis on each of the modulation signal groups, and determining the signal features of each of the modulation signal groups; S400: formulating a corresponding signal transmission strategy according to the signal features, and performing signal transmission evaluation and calculation on the signal transmission strategy, and respectively obtaining an evaluation value of the signal transmission strategy and a transmission evaluation value of the modulation signal group; S500: optimizing each of the signal transmission strategies in the modulation signal group based on the evaluation value and the transmission evaluation value, and obtaining a signal transmission optimization strategy for the modulation signal group; S600: performing long-distance signal transmission according to the signal transmission optimization strategy of the modulation signal group.

[0047] Furthermore, by formulating a corresponding signal transmission strategy based on the type and characteristics of the signal, and optimizing the signal transmission strategy to execute signal transmission, both the signal transmission quality and the signal transmission efficiency can be improved.

[0048] In an embodiment of the present application, a long-distance signal transmission optimization method is provided, wherein obtaining a signal to be transmitted and determining a signal type of the signal to be transmitted include: obtaining a signal to be transmitted and inputting the signal to be transmitted into a preset classification model; and determining the signal type of the signal to be transmitted by an output of the preset classification model.

[0049] Specifically, a classification model is established and trained in advance based on a machine learning algorithm to classify the signal to be transmitted. The preprocessed signal to be transmitted is input into the preset classification model. The model will analyze and classify the signal and give a corresponding output. The signal type of the signal to be transmitted is determined based on the output of the preset classification model.

[0050] In an embodiment of the present application, a method for optimizing long-distance signal transmission is provided, wherein a corresponding signal modulation method is selected according to the signal type to modulate the signal to be transmitted to obtain a plurality of modulated signal groups, including: obtaining the signal type of each signal in the signal to be transmitted, the signal type including an audio signal, a video signal and a data signal; analyzing the signal characteristics of the audio signal, the video signal and the data signal, and modulating the audio signal, the video signal and the data signal according to the signal characteristics to obtain an audio signal modulation group, a video signal modulation group and a data signal modulation group.

[0051] Specifically, according to the characteristics of audio signals, video signals and data signals, appropriate modulation methods are selected to modulate these signals. For example, amplitude modulation (AM) or frequency modulation (FM) modulation can be selected for audio signals, compression-based modulation methods (such as MPEG series) can be selected for video signals, and corresponding modulation methods (such as QAM, PSK, etc.) can be selected for data signals; according to the selected modulation methods, the corresponding audio signals, video signals and data signals are modulated respectively to generate audio signal modulation groups, video signal modulation groups and data signal modulation groups, each modulation group containing a modulated signal ready for transmission.

[0052] In an embodiment of the present application, a method for optimizing long-distance signal transmission is provided, wherein the characteristic analysis of each of the modulation signal groups is performed to determine the signal characteristics of each of the modulation signal groups, including: obtaining each signal in the audio signal modulation group, the video signal modulation group, and the data signal modulation group, and analyzing each signal to determine the characteristics of each signal; respectively counting the number of signals of each characteristic in the audio signal modulation group, the video signal modulation group, and the data signal modulation group, and taking the characteristics in which the number of signals in each of the modulation signal groups exceeds a preset value as the signal characteristics of the modulation signal group.

[0053] Specifically, each modulation signal group is obtained from the audio signal modulation group, the video signal modulation group and the data signal modulation group respectively; the signals in each modulation signal group are analyzed to determine their characteristics. For audio signals, the spectrum characteristics, volume characteristics, tone characteristics, etc. can be analyzed; for video signals, the resolution characteristics, frame rate characteristics, color characteristics, etc. can be analyzed; for data signals, the data rate characteristics, coding method characteristics, error control characteristics, etc. can be analyzed; the signal characteristics in each modulation signal group are counted, and the number of signals of each characteristic in the corresponding modulation signal group is counted according to preset values; the characteristics exceeding the preset values ​​are taken as the signal characteristics of the modulation signal group, and these characteristics represent characteristics with higher frequencies in the modulation signal group, which have an important impact on signal transmission and processing.

[0054] In an embodiment of the present application, a long-distance signal transmission optimization method is provided, wherein a corresponding signal transmission strategy is formulated according to the signal characteristics, and the signal transmission evaluation and calculation are performed on the signal transmission strategy to obtain an evaluation value of the signal transmission strategy and a transmission evaluation value of a modulation signal group, respectively, including: formulating a corresponding signal transmission strategy according to each of the signal characteristics, and evaluating each of the signal transmission strategies based on a plurality of preset evaluation indicators to obtain evaluation values ​​of a plurality of evaluation indicators; obtaining a transmission distance of the signal to be transmitted, and analyzing the influence of the distance on a plurality of evaluation indicators to obtain a correction coefficient for each evaluation indicator; and correcting each evaluation value according to the corresponding correction coefficient, and adding the corrected evaluation values ​​to obtain the transmission evaluation value of the modulation signal group.

[0055] Specifically, according to the previously determined signal characteristics, a corresponding transmission strategy is formulated for each signal. For example, for audio signals, appropriate compression algorithms and transmission protocols can be selected to reduce bandwidth requirements; for video signals, appropriate encoding algorithms and streaming media transmission methods can be selected to ensure picture quality and real-time performance; for data signals, appropriate error control and encryption methods can be selected to ensure data integrity and security; according to preset requirements and goals, multiple evaluation indicators are defined to evaluate the performance of each signal transmission strategy. For example, indicators such as transmission quality, transmission rate, delay, bandwidth occupancy, and power consumption can be considered; each signal transmission strategy is evaluated and the evaluation value of each evaluation indicator is calculated; according to the transmission distance of the signal to be transmitted, the influence of the distance on each evaluation indicator is analyzed, and the correction coefficient of each evaluation indicator is obtained, specifically: distance analysis, analyzing the influence of the transmission distance of the signal to be transmitted on each evaluation indicator, because the increase in transmission distance may cause problems such as signal attenuation and increased transmission delay; correction coefficient determination, according to the distance analysis results, the correction coefficient of each evaluation indicator is determined, and these correction coefficients represent the degree of influence of the transmission distance on each indicator; each evaluation value is corrected according to the correction coefficient, and the corrected evaluation values ​​are added to obtain the transmission evaluation value of the modulated signal group. Each evaluation value is corrected according to the previously determined correction coefficient. The original evaluation value is multiplied by the corresponding correction coefficient to obtain the corrected evaluation value; the corrected evaluation values ​​are added to obtain the transmission evaluation value of the modulated signal group, which comprehensively considers the impact of various signal characteristics, evaluation indicators and transmission distance on signal transmission performance.

[0056] In an embodiment of the present application, a long-distance signal transmission optimization method is provided, wherein each of the signal transmission strategies in the modulation signal group is optimized based on the evaluation value and the transmission evaluation value to obtain the signal transmission optimization strategy of the modulation signal group, including: obtaining the transmission evaluation value of the modulation signal group, and determining the number of simultaneous executions of each of the signal transmission strategies according to the transmission evaluation value; sorting each of the signal transmission strategies according to the size of the evaluation value, and using the sorted signal transmission strategy sequence as the execution order of the signal transmission strategy; optimizing each of the signal transmission strategies in the modulation signal group based on the simultaneous execution number and the execution order to obtain the signal transmission optimization strategy of the modulation signal group.

[0057] Specifically, the transmission evaluation value of the modulation signal group is calculated according to the previous steps; according to the transmission evaluation value, the number of simultaneous executions of each signal transmission strategy is determined, and a higher evaluation value usually indicates that the strategy has a greater impact on the transmission performance, so the strategy with a higher evaluation value has a smaller number of simultaneous executions, and vice versa; the various signal transmission strategies are sorted according to the size of the evaluation value, with the strategies with higher evaluation values ​​in front and the strategies with lower evaluation values ​​in the back; based on the number of simultaneous executions and the execution order, each signal transmission strategy in the modulation signal group is optimized to obtain a signal transmission optimization strategy, which can be carried out according to the following steps: simultaneous execution number allocation: according to the previously determined simultaneous execution number, the available simultaneous execution resources are allocated to each signal transmission strategy to ensure that the simultaneous execution number does not exceed the preset number to make full use of the available resources; execution order determination: according to the sorting of the signal transmission strategies, the execution order of the signal transmission strategies is determined, and the signal transmission strategies are executed in sequence according to the sorted strategy sequence; signal transmission optimization: during the execution process, the signal transmission strategy is optimized according to the simultaneous execution number and the execution order to maximize the signal transmission performance. The signal transmission strategy is optimized based on the number of simultaneous executions and the execution order, and the signal transmission optimization strategy of the modulated signal group is obtained, which helps to make full use of available resources and improve signal transmission performance.

[0058] In an embodiment of the present application, a long-distance signal transmission optimization method is provided, which optimizes each of the signal transmission strategies in the modulation signal group based on the simultaneous execution number and the execution order, including: sorting the signal transmission strategies according to the execution order, and judging the relationship between the simultaneous execution number and the number of signals in each of the modulation signal groups; if the simultaneous execution number exceeds the number of signal transmission strategies in each of the modulation signal groups, then grouping the signal transmission strategies in the modulation signal group into one transmission strategy for future transmission strategy execution; if the simultaneous execution number does not exceed the number of signal transmission strategies in each of the modulation signal groups, then sorting the signal transmission strategies in the modulation signal group according to the execution order for future transmission strategy execution.

[0059] Specifically, according to the previously determined execution order, the signal transmission strategies are sorted in order, and the sorted strategy sequence will be used for future transmission strategy execution; for each modulation signal group, the relationship between the number of transmission nodes and the number of signal transmission strategies therein is determined, and the number of simultaneous executions is compared with the number of signal transmission strategies in each modulation signal group; according to the judgment result, corresponding adjustments are made: if the number of simultaneous executions exceeds the number of signal transmission strategies in each modulation signal group, the various signal transmission strategies in the modulation signal group are classified as one transmission strategy, so that the transmission of multiple signals can be merged into one transmission strategy for future transmission strategy execution; if the number of simultaneous executions does not exceed the number of signal transmission strategies in each modulation signal group, the various signal transmission strategies in the modulation signal group are sorted according to the execution order, and the original transmission strategy order can be maintained for future transmission strategy execution. Through this process, the signal transmission strategies can be sorted according to the execution order, and corresponding adjustments can be made according to the relationship between the number of simultaneous executions and the number of signals in each modulation signal group, so as to ensure the rationality of the execution order and number of transmission strategies, so as to improve the efficiency of signal transmission.
