[0046] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0047] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0048] like Figure 1 As shown, the first aspect of the present invention provides a data transmission method of an optical communication system, comprising the following steps:

[0049] S102: Acquire communication quality data of the optical communication system under various environmental factors, and construct an optical communication quality prediction model based on the communication quality data of the optical communication system under various environmental factors;

[0050] It should be noted that the impact of atmospheric turbulence on wireless optical communication systems is mainly caused by the difference between the laser diameter and the size of turbulence. When the turbulence is much larger than the laser diameter, the laser projection point will have a phenomenon of light beam drifting. When the turbulence and laser diameters are almost the same or the turbulence is much smaller than the laser diameter, a broadening effect will appear on the receiving plane, resulting in different light intensities, flickering, and flickering. The atmospheric turbulence effect generally occurs in various weather conditions, but the temperature and humidity of the laser transmission environment will change due to differences in temperature and sunlight intensity, and the effect will also be different. Generally, the humidity is low on sunny days and the atmospheric turbulence effect is weak.

[0051] Therefore, in step S102, the following steps are specifically included:

[0052] The communication quality data of the optical communication system under various environmental factors is obtained through big data, and the graph neural network is introduced to input the communication quality data of the optical communication system under various environmental factors into the graph neural network, with the environmental factor as the first node and the communication quality data as the second node;

[0053] Constructing a directed edge description relationship, connecting the first node and the second node based on the directed edge description relationship, constructing a topological structure graph, obtaining a corresponding adjacency matrix based on the topological structure graph, and constructing an optical communication quality prediction model based on a deep neural network;

[0054] Initializing model parameters of the optical communication quality prediction model, and inputting the relevant adjacency matrix into the optical communication quality prediction model, and when the model parameters of the optical communication quality prediction model are not within a preset range, continuously training the optical communication quality prediction model;

[0055] When the model parameters of the optical communication quality prediction model are within a preset range, the training of the optical communication quality prediction model is terminated, the model training is completed, and the optical communication quality prediction model is output.

[0056] It should be noted that environmental factors include temperature, humidity, raindrop diameter, snow, fog and other data. Among them, communication quality data includes bit error rate, transmission rate and other data. Through this method, an optical communication quality prediction model can be constructed to predict communication quality data according to environmental factor data. Among them, the model parameters of the optical communication quality prediction model include prediction accuracy, convergence value of loss function and other data.

[0057] S104: obtaining geographical location information of the optical communication device transmitting end and each receiving end in the target area, constructing a transmission link based on the geographical location information of the optical communication device transmitting end and each receiving end, and obtaining optical communication quality data of each transmission link based on a communication quality prediction model;

[0058] It should be noted that, in step S104, the following steps are also included:

[0059] Obtaining geographical location information of the transmitting end of the optical communication equipment and each receiving end in the target area, and obtaining environmental factor data corresponding to the geographical location information of the transmitting end of the optical communication equipment and each receiving end through big data;

[0060] Constructing a plurality of transmission links based on the geographical location information of the transmitting end of the optical communication equipment and each receiving end in the target area, and obtaining the geographical location area through which the transmission link path passes, and obtaining the environmental factor data of the geographical location area through which the transmission link path passes;

[0061] The geographical location areas corresponding to the adjacent areas and the same environmental factor data are merged into one area and used as a sub-area, and the rest are used as sub-areas, and the environmental factor data corresponding to the transmission link path passed by each sub-area is obtained;

[0062] The environmental factor data corresponding to the transmission link path passed by each sub-area is input into the communication quality prediction model to obtain the communication quality data corresponding to the environmental factor data corresponding to the transmission link path passed by each sub-area, and the optical communication quality data of each transmission link is obtained based on the communication quality data corresponding to the environmental factor data corresponding to the transmission link path passed by each sub-area.

[0063] It should be noted that, generally speaking, in an optical communication system, a transmission link is formed by a transmitting end and a receiving end. Through this method, the optical communication quality data of each transmission link can be obtained according to the communication quality data corresponding to the environmental factor data corresponding to the transmission link path passed by each sub-area, which includes the following steps:

[0064] Setting a critical communication quality data threshold, and determining whether the communication quality data corresponding to the environmental factor data corresponding to the transmission link path passed by each sub-area is lower than the critical communication quality data threshold;

[0065] When the communication quality data corresponding to the environmental factor data corresponding to the transmission link path passed by the sub-area is lower than the limit communication quality data threshold, the limit communication quality data threshold is output as the communication quality data of the corresponding transmission link;

[0066] When the communication quality data corresponding to the environmental factor data corresponding to the transmission link path passed by the sub-area is not lower than the limit communication quality data threshold, the average value of the communication quality data corresponding to the environmental factor data corresponding to the transmission link path passed by each sub-area is calculated and used as the optical communication quality data of the corresponding transmission link.

[0067] It should be noted that when the communication quality data corresponding to the environmental factor data corresponding to the transmission link path passed by the sub-area is lower than the limit communication quality data threshold, it means that the transmission link cannot transmit data. At this time, the limit communication quality data threshold is used as the communication quality data of the corresponding transmission link. When the communication quality data corresponding to the environmental factor data corresponding to the transmission link path passed by the sub-area is not lower than the limit communication quality data threshold, it means that the transmission link can transmit data. Then, the average value of the communication quality data corresponding to the environmental factor data corresponding to the transmission link path passed by each sub-area is calculated and used as the optical communication quality data of the corresponding transmission link.

[0068] S106: setting an optical communication quality data threshold, and preliminarily selecting candidate transmission links based on the optical communication quality data of each transmission link and the optical communication quality data threshold;

[0069] It should be noted that, in step S106, the following may be specifically included:

[0070] Set the optical communication quality data threshold (need to reach a certain bit error rate and information transmission rate), and determine whether the optical communication quality data of the transmission link is greater than the optical communication quality data threshold;

[0071] When the optical communication quality data of the transmission link is greater than the optical communication quality data threshold, the corresponding transmission link is used as a candidate transmission link;

[0072] When the optical communication quality data of the transmission link is not greater than the optical communication quality data threshold, the corresponding transmission link is regarded as a non-candidate transmission link.

[0073] S108: Generate an information transmission plan based on the candidate transmission links, and transmit information according to the information transmission plan.

[0074] like Figure 2 As shown, further, in this method, an information transmission plan is generated based on the candidate transmission link, and information transmission is performed according to the information transmission plan, specifically including:

[0075] S202: obtaining data on the amount of information to be transmitted within a unit time, and obtaining data on the maximum amount of information transmitted by candidate transmission links, initializing the number of candidate transmission links, and randomly selecting candidate transmission links to form a candidate transmission link combination;

[0076] S204: introducing a particle swarm algorithm, setting the number of iterations based on the particle swarm algorithm, calculating the total information transmission volume data of the candidate transmission link combination within a unit time based on the maximum information transmission volume data of the candidate transmission link, and determining whether the total information transmission volume data is not greater than the required information volume data to be transmitted within a unit time;

[0077] S206: When the total information transmission amount data is not greater than the required information amount data to be transmitted within a unit time, iterate the candidate transmission link combination based on the number of iterations, and adjust the candidate transmission links in the candidate transmission link combination until the total information transmission amount data is greater than the required information amount data to be transmitted within a unit time;

[0078] S208: When the total amount of information transmission data is greater than the amount of information to be transmitted within a unit time, a candidate transmission link combination is output, and an information transmission plan is generated based on the candidate transmission link combination, and information transmission is performed according to the information transmission plan.

[0079] It should be noted that, since the amount of information transmitted per unit time in an information transmission link is limited, the method can optimize the transmission link combination and improve the success rate of information transmission during optical communication.

[0080] It is worth mentioning that the present invention fully considers the impact of environmental factors on communication quality, thereby configuring the optimal transmission link according to actual transmission requirements, so that the data transmission success rate in optical communication is higher.

[0081] Additionally, the following steps may be included:

[0082] Obtaining content data of each type of particulate matter in the air, and testing the light absorption characteristics of the optical communication system in the content data of each type of particulate matter to obtain light absorption characteristic data of each type of particulate matter and under the content;

[0083] Acquire optical characteristic data of the optical communication system during the communication process, and acquire real-time optical characteristic data based on the optical characteristic data of the optical communication system during the communication process and the optical absorption characteristic data of each particle type and content;

[0084] Presetting a light characteristic data threshold of the optical communication system during communication, and determining whether the real-time light characteristic data is not greater than the light characteristic data threshold of the optical communication system during communication;

[0085] When the real-time optical characteristic data is not greater than the optical characteristic data threshold of the optical communication system during communication, the optical characteristic data of the optical communication system during communication is adjusted until the real-time optical characteristic data is greater than the optical characteristic data threshold of the optical communication system during communication.

[0086] It should be noted that the absorption and scattering of light by various substances in the atmosphere will have an impact on the wireless optical communication system. The molecules in the atmosphere have strong absorption characteristics, but this absorption characteristic is selective and will be selected according to the wavelength of light, but in any case it will affect the propagation of light, such as 2% of red light is absorbed by haze. In addition, there are various particles of different sizes and numbers in the atmosphere. When light passes through these uneven substances, it will also produce scattering effects, which will weaken the light energy during the propagation process and produce uneven distribution of light spots. These situations will also have a significant impact on the propagation of light. The substances in the atmosphere cause loss in the process of light propagation in the atmosphere through different means such as absorption and scattering of light, and the corresponding atmospheric attenuation effect will cause instability in the wireless optical communication system. Among them, the optical characteristic data includes data such as power, frequency, wavelength, etc. of the optical communication system. This method can optimize optical communication transmission.

[0087] In addition, the method may further comprise the following steps:

[0088] Obtaining content data of each type of particle in the air within a preset time through big data, and obtaining light absorption characteristic data within each sub-preset time according to the content data of each type of particle in the air within the preset time;

[0089] Setting a limit light absorption characteristic data threshold, and determining whether the light absorption characteristic data within the sub-preset time is greater than the limit light absorption characteristic data threshold;

[0090] When the light absorption characteristic data within the sub-preset time is not greater than the limit light absorption characteristic data threshold, the corresponding sub-period is used as the data transmission communication period of the optical communication system;

[0091] When the light absorption characteristic data within the sub-preset time is greater than the limit light absorption characteristic data threshold, the corresponding sub-time period is not used as the data transmission communication period of the optical communication system, and data communication is performed on the optical communication system according to the data transmission communication period of the optical communication system.

[0092] It should be noted that, within a certain period of time, when the light absorption characteristic data within the sub-preset time is not greater than the limit light absorption characteristic data threshold, it means that the time period is suitable for data transmission, otherwise, it is not suitable for transmission. This method improves the rationality of data transmission in the optical communication system.
