[0108] A quantity determination module, used for determining the number of idle data transmission channels when there are idle data transmission channels in the data receiving unit;

[0109] A historical communication operation record retrieval module is used to extract the historical communication operation record of the data transmission channel currently in the idle state when the number of the data transmission channels in the idle state is multiple;

[0110] A data extraction module, used to retrieve the channel usage rate of each idle data transmission channel per unit time and the channel capacity occupancy rate when the channel is in use from the historical communication operation record of the data transmission channel currently in an idle state; wherein the value range of the unit time is 24h-72h;

[0111] The first channel evaluation parameter acquisition module is used to obtain the first channel evaluation parameter by using the channel usage rate of each data transmission channel in the idle state within a unit time and the channel capacity occupancy rate when the channel is in use, wherein the first channel evaluation parameter is obtained by the following formula:

[0112] ;

[0113] Among them, S 01 represents the first channel evaluation parameter currently corresponding to each idle data transmission channel; n represents the number of unit time experienced by the data transmission channel; P si represents the channel utilization rate of the data transmission channel corresponding to the i-th unit time; P maxi represents the maximum channel capacity occupancy rate of the data transmission channel in the i-th unit time; P mini represents the minimum channel capacity occupancy rate of the data transmission channel in the i-th unit time; T maxi It indicates the duration of the maximum channel capacity occupancy rate of the data transmission channel in the i-th unit time; T mini It indicates the duration of the minimum channel capacity occupancy rate of the data transmission channel in the i-th unit time; T n represents the duration corresponding to the unit time; f represents the adjustment coefficient, and the adjustment coefficient is obtained by the following formula:

[0114] ;

[0115] Where n represents the number of unit time experienced by the data transmission channel; P maxi represents the maximum channel capacity occupancy rate of the data transmission channel in the i-th unit time; P mini Indicates the minimum channel capacity occupancy rate of the data transmission channel in the i-th unit time; B maxi represents the bandwidth utilization rate corresponding to the maximum channel capacity occupancy rate of the data transmission channel in the i-th unit time; B mini It represents the bandwidth utilization rate corresponding to the minimum channel capacity occupancy rate of the data transmission channel in the i-th unit time;

[0119] The second channel determination module is configured to select a channel currently used for data transmission from among the candidate channels when there are multiple candidate channels.

[0120] The technical effect of the above technical solution is: by introducing a quantity determination module, a historical communication operation record retrieval module, a data extraction module, etc., the technical solution can comprehensively evaluate the performance and stability of the currently idle data transmission channel. This helps to consider not only the immediate status of the channel when selecting a data transmission channel, but also its historical operation data, so as to more scientifically select the optimal channel and improve the efficiency and reliability of data transmission. Through the first channel evaluation parameter acquisition module, a complex calculation formula is used to comprehensively consider factors such as the channel utilization rate per unit time, the channel capacity occupancy rate and its duration, and the bandwidth utilization rate, and the overall performance of the channel is quantitatively evaluated. This quantitative evaluation method is more comprehensive and accurate than relying solely on a certain indicator, and helps to more accurately reflect the actual performance of the channel.

[0121] The technical solution includes a comparison module, a candidate channel determination module, and a second channel determination module. These modules work together to dynamically adjust the selection of data transmission channels according to real-time data and preset conditions. When the number of candidate channels is one, it is directly selected; when the number of candidate channels is large, it is further screened. This design enables the system to flexibly respond to different data transmission requirements and environmental changes, improving the adaptability and flexibility of the system. By accurately evaluating and selecting data transmission channels, resource waste or performance bottlenecks caused by improper selection can be avoided. At the same time, the introduction of historical communication operation records also enables the system to better predict and plan future data transmission needs, thereby optimizing resource allocation in advance and further improving the utilization of system resources. Selecting a data transmission channel with better performance for data transmission can reduce the risk of data transmission interruption or delay due to channel failure or insufficient performance. This is particularly important for data transmission applications that require high reliability and stability, such as financial transactions, medical data transmission, etc.

[0122] In summary, this technical solution achieves comprehensive and accurate evaluation and dynamic selection of data transmission channels by introducing a series of modules and complex evaluation algorithms, effectively improving the efficiency and reliability of data transmission, while enhancing the adaptability and flexibility of the system.

[0123] Specifically, the second channel determination module includes:

[0124] A channel screening module, used for retrieving a channel corresponding to a maximum value of the first channel evaluation parameter and a channel corresponding to a minimum value of the first channel evaluation parameter from among the candidate channels when there are multiple candidate channels;

[0125] A first target channel acquisition module, configured to take a channel corresponding to a maximum value of the first channel evaluation parameter as a first target channel;

[0126] A second target channel acquisition module, used for taking the channel corresponding to the maximum value of the second channel evaluation parameter as the second target channel;

[0127] A first channel evaluation parameter retrieving module, used to retrieve the first channel evaluation parameters appearing in the historical communication operation records corresponding to the first target channel and the second target channel;

[0128] A comprehensive evaluation parameter acquisition module is used to obtain second channel evaluation parameters corresponding to the first target channel and the second target channel using the first channel evaluation parameters appearing in the historical communication operation records corresponding to the first target channel and the second target channel; wherein the second channel evaluation parameters are obtained by the following formula:

[0129] ;

[0130] Among them, S 02 represents the second channel evaluation parameter corresponding to the first target channel and the second target channel; m represents the historical number of occurrences of the first channel evaluation parameter corresponding to the first target channel and the second target channel; S 01i represents the parameter value of the first channel evaluation parameter corresponding to the first target channel and the second target channel for the i-th occurrence; S 01x S represents the first channel evaluation parameter currently corresponding to the first target channel and the second target channel; y Indicates the preset evaluation parameter threshold; S c Indicates the difference between the first channel evaluation parameters currently corresponding to the first target channel and the second target channel;

[0131] The channel determination execution module is used to use the target channel corresponding to the minimum value of the second channel evaluation parameters corresponding to the first target channel and the second target channel as the channel currently used for data transmission.

[0132] The technical effect of the above technical solution is: when there are a large number of candidate channels, the channel screening module can quickly locate the channels corresponding to the maximum and minimum values ​​of the first channel evaluation parameter, that is, the channels with the best performance and relatively poor performance. This screening method helps to consider the channel performance more comprehensively in the subsequent comprehensive evaluation and improve the accuracy of the selection. The determination of the first target channel and the second target channel not only considers the maximum and minimum values ​​of a single evaluation parameter (that is, the first channel evaluation parameter), but also introduces a new evaluation dimension through the calculation of the second channel evaluation parameter. This new evaluation dimension combines historical performance, current status and preset standards, making the selection of channels more comprehensive and scientific.

[0133] The comprehensive evaluation parameter acquisition module uses a complex calculation formula to combine the first channel evaluation parameters of the first target channel and the second target channel that appear in the historical communication operation records, as well as their relative relationship with the preset evaluation parameter threshold and the current state, to obtain a more comprehensive and accurate second channel evaluation parameter. This comprehensive evaluation method reduces the deviation that may be caused by single indicator evaluation and improves the accuracy of the selection. By comparing the second channel evaluation parameters of the first target channel and the second target channel, and selecting the target channel corresponding to the minimum parameter value as the current channel for data transmission, the technical solution shows good adaptability and flexibility. It can flexibly select the optimal channel from multiple candidate channels based on the comprehensive evaluation results to meet different data transmission requirements.

[0134] Through precise screening and comprehensive evaluation, the technical solution can select the data transmission channel with the best performance and highest stability, thereby improving the efficiency and reliability of data transmission. This is especially important for application scenarios that require high performance and stability (such as real-time data processing, high-reliability communications, etc.). Selecting the optimal channel for data transmission can maximize the use of system resources and reduce resource waste and cost increases caused by insufficient channel performance or failures.

[0135] In summary, this technical solution achieves accurate screening and comprehensive evaluation of candidate channels by introducing the second evaluation dimension and comprehensive evaluation method, improves the accuracy and scientificity of data transmission channel selection, thereby improving system performance and stability and reducing resource waste.
