DETAILED DESCRIPTION

[0039] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0040] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the drawings in the embodiments of the present application are collected below to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] An embodiment of the present application provides a satellite communication method based on microwaves and lasers, which can be executed by an electronic device, wherein the electronic device can be a server, wherein the server can be an independent physical server, or a server cluster or distributed device composed of multiple physical servers, or a cloud server that provides cloud computing services; the server can be installed in a ground communication terminal.

[0042] Reference Figure 1, a satellite communication method based on microwaves and lasers includes: step S101, step S102 and step S103, wherein,

[0043] S101, obtaining data to be forwarded from a ground terminal.

[0044] In some embodiments, the data to be forwarded is the same batch of data sent by the ground terminal to the target satellite.

[0045] The electronic device obtains the same batch of data to be forwarded that the ground terminal pre-sends to the target satellite from the ground terminal, analyzes and processes the data to be forwarded, and determines the data type contained in the data to be forwarded and the data volume corresponding to each data type; based on the specific situation of the data to be forwarded, the electronic device sets a preset data integration rule corresponding to the data to be forwarded, and the subsequent electronic device reconstructs and integrates the data to be forwarded based on the preset data integration rule.

[0046] The electronic device sets corresponding data reconstruction and integration methods for different types of data in the data to be forwarded, and can use the data volume as reference information for determining the data forwarding instructions corresponding to the data to be forwarded; subsequently, the electronic device reconstructs and integrates the data to be forwarded based on preset data integration rules.

[0047] S102, calling the preset data integration rule corresponding to the data to be forwarded, reconstructing and integrating the data to be forwarded, and obtaining target forwarding data.

[0048] In some embodiments, the data to be forwarded includes communication link data and text data; the communication link data is communication link verification data.

[0049] Before the ground terminal and the target satellite transmit data, a communication connection needs to be established between the ground terminal and the target satellite, and the verification of the communication connection is completed. After the two have the data transmission function, the main text data is transmitted; therefore, it is necessary to transmit the relevant communication verification data first, and after the relevant communication verification data is completed and the two have the data transmission function, the main text data is transmitted.

[0050] In some embodiments, the electronic device calls a preset data integration rule corresponding to the data to be sent, determines the data of each data type contained in the data to be forwarded, and sets forwarding priorities for each type of data based on the data forwarding level corresponding to the preset data type. Subsequently, the data is reintegrated based on the set forwarding priority to obtain reconstructed and integrated data to be forwarded, i.e., the target forwarding data.

[0051] S103, generating a data forwarding instruction based on the target forwarding data, and using the data forwarding instruction to control the target satellite to receive the target forwarding data in a laser communication mode or a microwave communication mode.

[0052] In some embodiments, the electronic device generates a corresponding data forwarding instruction based on the target forwarding data, wherein the data forwarding instruction includes a laser data forwarding instruction and a microwave data forwarding instruction, and is intended to transmit different types of data in the target forwarding data to the target satellite through their respective corresponding data forwarding methods, that is, based on the generated data forwarding instruction, the target satellite is controlled to receive the target forwarding data in a laser communication mode or a microwave communication mode; thereby, through the reconstruction and integration of the data to be forwarded, the data suitable for the same communication mode is integrated, thereby reducing the switching frequency of different communication modes of subsequent target satellites. At the same time, through the communication mode adapted to the target forwarding data, the transmission security and rate of the data to be forwarded are improved while reducing the waste of laser communication resources.

[0053] In some embodiments, during the transmission of data of different data types in the target forwarding data, the data volume of the data of different data types can be determined, and the data volume can be used as reference information for determining the transmission method of the data corresponding to the data volume, that is, generating the corresponding data forwarding instruction; for example, after the data transmission received in the laser communication mode is completed, the process of switching to the microwave communication mode to receive the corresponding data is first determined. In the case that the data volume is too small, it can be considered not to use the pre-set microwave communication mode for transmission, and the laser communication mode can continue to be used for transmission, thereby reducing the switching frequency of the communication mode of the target satellite.

[0054] In step S102, the preset data integration rule corresponding to the data to be forwarded is called to reconstruct and integrate the data to be forwarded to obtain target forwarding data, including: based on the preset data integration rule, at least two groups of communication link data and at least two groups of text data are screened out from the data to be forwarded; at least two groups of communication link data are set as the highest priority forwarding level, and at least two groups of text data are set as the second priority forwarding level; based on the highest priority forwarding level, at least two groups of communication link data are integrated to obtain a first communication link data group; and based on the second priority forwarding level, at least two groups of text data are integrated to obtain a first text data group; based on the first communication link data group and the first text data group, the target forwarding data is determined.

[0055] In some embodiments, the electronic device first performs data analysis and screening on the data to be forwarded based on preset data integration rules, and screens out at least two groups of communication link data and at least two groups of text data from the data to be forwarded based on the data type corresponding to the data contained in the data to be forwarded; since the communication link data is data for verifying whether the laser communication and microwave communication connections between the ground terminal and the target satellite are normal, the communication link data needs to be forwarded before the text data is transmitted.

[0056] Therefore, the electronic device sets at least two groups of communication link data as the highest priority forwarding level, and sets at least two groups of text data as the second priority forwarding level; since at least two groups of communication link data are data of the same data type, the electronic device can integrate at least two groups of communication link data to obtain a first communication link data group, which will be subsequently transmitted together; and since at least two groups of text data are data of the same data type, at least two groups of text data can be integrated to obtain a first text data group, which will be subsequently transmitted together; thereby completing the preliminary reconstruction and integration of the data to be forwarded; subsequently, the electronic device determines the target forwarding data based on the first communication link data group and the first text data group.

[0057] In some embodiments, based on the first communication link data group and the first main text data group, determining the target forwarding data includes: based on a preset data integration rule, filtering out microwave communication connection data and laser communication connection data from the first communication link data group, and obtaining data forwarding emergency information corresponding to the data to be forwarded generated by the ground terminal; in a case where the data forwarding emergency information is the preset data forwarding emergency information, setting the laser communication connection data to a first priority forwarding level, and setting the microwave communication connection data to a second priority forwarding level; based on the first priority forwarding level and the second priority forwarding level, integrating the microwave communication connection data and the laser communication connection data to obtain a second communication link data group; based on the second communication link data group and the first main text data group, determining the target forwarding data.

[0058] In some embodiments, since the ground terminal and the target satellite have data transmission in laser communication mode and data transmission in microwave communication mode, and the second communication link data group includes verification data of the laser communication mode between the ground terminal and the target satellite and verification data of the microwave communication mode between the ground terminal and the target satellite, therefore, during the transmission of the second communication link data group, it is also necessary to clarify the transmission priority of the verification data of the laser communication mode between the ground terminal and the target satellite and the verification data of the microwave communication mode between the ground terminal and the target satellite.

[0059] That is, the electronic device first filters out the microwave communication connection data and the laser communication connection data from the first communication link data based on the preset data integration rules, and simultaneously obtains the data forwarding emergency information corresponding to the data to be forwarded generated by the ground terminal, and determines whether the data forwarding emergency information is the preset data forwarding emergency information; when the electronic device determines that the data forwarding emergency information is the preset data forwarding emergency information, it indicates that the transmission security and rate requirements of the data to be forwarded are high, and therefore, the electronic device sets the laser communication connection data to the first priority forwarding level, and subsequently gives priority to forwarding, that is, prioritizes verifying the laser communication mode between the ground terminal and the target satellite; and sets the microwave communication connection data to the second priority forwarding level.

[0060] Subsequently, the electronic device integrates the microwave communication connection data and the laser communication connection data based on the first priority forwarding level and the second priority forwarding level, thereby obtaining a reconstructed and integrated first communication link data group, that is, a second communication link data group; the subsequent electronic device determines the target forwarding data based on the second communication link data group and the first text data group.

[0061] In some embodiments, based on the first communication link data group and the first text data group, target forwarding data is determined, including: based on a preset data integration rule, screening out at least two groups of encrypted data and at least two groups of non-encrypted data from the first text data group; setting at least two groups of encrypted data to a third priority forwarding level, and setting at least two groups of non-encrypted data to a fourth priority forwarding level; based on the third priority forwarding level and the fourth priority forwarding level, integrating at least two groups of encrypted data and at least two groups of non-encrypted data to obtain a second text data group; based on the first communication link data group and the second text data group, target forwarding data is determined.

[0062] In some embodiments, the electronic device reconstructs and integrates the first communication link data group while also reconstructing and integrating the first text data group; wherein the first text data may include encrypted data or unencrypted data; the encrypted data is generally specific parameters, etc., and the unencrypted data is generally tag data, etc.; that is, the electronic device first screens out at least two groups of encrypted data and at least two groups of unencrypted data contained in the first text data group based on preset data integration rules; due to the high security requirements and transmission rate requirements for encrypted data transmission, the transmission priority of the encrypted data can be set higher than the transmission priority of the unencrypted data; that is, the electronic device sets at least two groups of encrypted data to the third priority forwarding level, and sets at least two groups of non-confidential data to the fourth priority forwarding level, wherein the priority of the third priority forwarding level is higher than the priority of the fourth priority forwarding level.

[0063] Subsequently, the electronic device integrates at least two groups of encrypted data and at least two groups of non-confidential data based on the third priority forwarding level and the fourth priority forwarding level, thereby obtaining a reconstructed and integrated first text data group, that is, a second text data group; subsequently, the electronic device determines the target forwarding data based on the second communication link data group and the first text data group.

[0064] In some embodiments, the electronic device integrates the obtained second communication link data group and the second body data group to obtain target forwarding data.

[0065] In step S103, a data forwarding instruction is generated based on the target forwarding data, and the data forwarding instruction is used to control the target satellite to receive the target forwarding data in a laser communication mode or a microwave communication mode, including: when the second communication link data group included in the target forwarding data needs to be forwarded, a first microwave data forwarding instruction is generated, and the first microwave data forwarding instruction is used to control the target satellite to receive the second communication link data group in the microwave communication mode;

[0066] When the forwarding of the second communication link data group is completed and the target forwarded data packet contains encrypted data, a laser data forwarding instruction is generated, and the laser data forwarding instruction is used to control the target satellite to receive the encrypted data in laser communication mode; when the forwarding of the encrypted data is completed and the target forwarded data packet contains non-encrypted data, the data volume of the non-encrypted data is determined; when the data volume is greater than the preset data volume, a second microwave data forwarding instruction is generated, and the second microwave data forwarding instruction is used to control the target satellite to receive the non-encrypted data in microwave communication mode.

[0067] In some embodiments, the electronic device reconstructs and integrates the data to be forwarded, obtains the target forwarding data, and then starts to transmit the target forwarding data based on the laser communication mode or the microwave communication mode; in the process of the ground terminal transmitting the target forwarding data to the target satellite, when the second communication link data group included in the target forwarding data needs to be forwarded, a first microwave data forwarding instruction is generated, and the first microwave data forwarding instruction is sent to the ground terminal and the target satellite, thereby controlling the target satellite to receive the second communication link data group in the microwave communication mode; thereby, by taking advantage of the stable transmission characteristic of the microwave communication mode, the stability of the second communication link data group transmitted to the target satellite is improved, so that the communication connection verification between the ground terminal and the target satellite is completed.

[0068] After the transmission of the second communication link data is completed, the second text data contained in the target forwarding data can be transmitted. Since the transmission priority of the encrypted data in the second text data is high, the encrypted data is transmitted first. That is, when the electronic device determines that the forwarding of the second communication link data group contained in the target forwarding data is completed and there is encrypted data in the second text data contained in the target forwarding data, the electronic device generates a laser data forwarding instruction and sends the laser data forwarding instruction to the ground terminal and the electronic device, thereby controlling the target satellite to receive the encrypted data in the laser communication mode, thereby improving the security of encrypted data transmission based on the characteristics of high transmission security and fast transmission rate in the laser communication mode.

[0069] After the transmission of confidential data in the second body data is completed, the non-encrypted data in the second body data contained in the target forwarding data begins to be transmitted. Since the requirements for the security and transmission rate of non-confidential data are lower than those for encrypted data, it is possible to consider transmitting the data by microwave transmission. Whether to use microwave transmission for transmission requires judging the data volume of non-confidential data, that is, the electronic device determines the data volume of non-encrypted data when the encrypted data forwarding is completed and the target forwarding data contains non-encrypted data; then, the electronic device determines whether the data volume is greater than the preset data volume, and when it is determined that the data volume is greater than the preset data volume, it determines that the microwave transmission mode can be used for transmission, and then the electronic device generates a second microwave data instruction, and sends the second microwave data instruction to the ground terminal and the target satellite, thereby controlling the target satellite to receive non-confidential data in microwave communication mode.

[0070] In some embodiments, after determining the amount of non-encrypted data, a data forwarding instruction is generated based on the target forwarding data, and the data forwarding instruction is used to control the target satellite to receive the target forwarding data in a laser communication mode or a microwave communication mode. It also includes: when the amount of non-encrypted data is not greater than a preset data amount, the laser data forwarding instruction is used to control the target satellite to receive the non-encrypted data based on the laser communication mode.

[0071] In some embodiments, when the electronic device determines that the amount of non-encrypted data is not greater than a preset data amount, it indicates that the amount of non-encrypted data is too small and it can continue to be transmitted through the laser communication mode, thereby reducing unnecessary switching of the communication mode of the target satellite. That is, the electronic device sends the laser data forwarding instruction to the ground terminal and the target satellite again, thereby controlling the target satellite to receive non-confidential data based on the laser communication mode.

[0072] In some embodiments, after controlling the target satellite to receive the second communication link data group in a microwave communication mode based on a first microwave data forwarding instruction, a data forwarding instruction is generated based on the target forwarding data, and the data forwarding instruction is used to control the target satellite to receive the target forwarding data in a laser communication mode or a microwave communication mode. It also includes: when the second communication link data group is forwarded and the target forwarding data packet contains encrypted data, determining the security level of the encrypted data; when the security level is lower than a preset level, generating a third microwave data forwarding instruction, and using the third microwave data forwarding instruction to control the target satellite to receive the encrypted data in a microwave communication mode.

[0073] In some embodiments, when the electronic device determines that the forwarding of the second communication link data group is completed and the target forwarded data packet contains encrypted data, the electronic device determines the security level corresponding to the encrypted data, wherein the electronic device matches the encrypted data with a preset security level to determine its corresponding security level; then, the electronic device compares the security level with the preset security level, and when it is determined that the security level is lower than the preset level, it indicates that the security of the encrypted data is low, and the problem of being intercepted during the transmission process is not considered. Therefore, in the process of transmitting the encrypted data, it can be considered to transmit it through the microwave communication mode, that is, the electronic device generates a third microwave data forwarding instruction, and sends the third microwave data forwarding instruction to the ground terminal and the target satellite, thereby controlling the target satellite to receive the encrypted data in the microwave communication mode.

[0074] In some embodiments, after the ground terminal completes the transmission of the laser communication connection data in the second communication link data, the laser communication mode verification process between the ground terminal and the target satellite is performed simultaneously with the ground terminal's transmission of the microwave communication connection data in the second communication link data to improve the verification efficiency of the communication connection between the ground terminal and the target satellite.
