And then the electronic equipment 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, so that a reconstructed and integrated first communication link data set is obtained, namely a second communication link data set is obtained, and the subsequent electronic equipment determines target forwarding data based on the second communication link data set and the first text data set.
In some embodiments, determining the target forwarding data based on the first communication link data set and the first text data set includes screening at least two sets of encrypted data and at least two sets of non-encrypted data from the first text data set based on a preset data integration rule, setting the at least two sets of encrypted data to a third priority forwarding level and the at least two sets of non-encrypted data to a fourth priority forwarding level, integrating the at least two sets of encrypted data and the at least two sets of non-encrypted data based on the third priority forwarding level and the fourth priority forwarding level to obtain a second text data set, and determining the target forwarding data based on the first communication link data set and the second text data set.
In some embodiments, the electronic device reconstructs and integrates the first text data set while reconstructing and integrating the first communication link data set, wherein the first text data may include encrypted data and may also include non-encrypted data, the encrypted data is generally specific parameters, the non-encrypted data is generally label data, and the like, that is, the electronic device firstly screens at least two groups of encrypted data and at least two groups of non-encrypted data included in the first text data set based on a preset data integration rule, and due to higher security requirements and higher transmission rate requirements of the encrypted data transmission, the transmission priority of the encrypted data can be set higher than the transmission priority of the non-encrypted data, that is, the electronic device sets the at least two groups of encrypted data as a third priority forwarding level and sets the at least two groups of non-confidential data as a fourth priority forwarding level, wherein the third priority forwarding level is higher than the fourth priority forwarding level.
And the electronic equipment 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, so that a first text data group after reconstruction and integration is obtained, namely a second text data group is obtained, and the subsequent electronic equipment determines target forwarding data based on the second communication link data group and the first text data group.
In some embodiments, the electronic device integrates the second communication link data set and the second text data set, thereby obtaining the target forwarding data.
In step S103, generating a data forwarding instruction based on the target forwarding data, and controlling the target satellite to receive the target forwarding data in a laser communication mode or a microwave communication mode by using the data forwarding instruction, wherein the data forwarding instruction comprises the steps of generating a first microwave data forwarding instruction when a second communication link data set contained in the target forwarding data needs to be forwarded, and controlling the target satellite to receive the second communication link data set in the microwave communication mode by using the first microwave data forwarding instruction;

After the transmission of the second communication link data is completed, the second text data contained in the target forwarding data can be transmitted, and the encrypted data is preferentially transmitted because the transmission priority of the encrypted data in the second text data is high, namely, the electronic equipment judges that the forwarding of the second communication link data group contained in the target forwarding data is completed, and under the condition that the encrypted data exists in the second text data contained in the target forwarding data, the electronic equipment generates a laser data forwarding instruction and sends the laser data forwarding instruction to the ground terminal and the electronic equipment, so that the target satellite is controlled to receive the encrypted data in a laser communication mode, and the electronic equipment has the characteristics of high transmission safety and high transmission speed based on the laser communication mode, thereby improving the safety of the transmission of the encrypted data.
After the transmission of the confidential data in the second text data is completed, the transmission of the non-encrypted data in the second text data contained in the target forwarding data is started, and because the requirements on the security and the transmission rate of the non-confidential data are lower than those of the encrypted data, the transmission can be considered in a microwave transmission mode, wherein whether the transmission is performed in the microwave transmission mode or not needs to be judged, namely, the electronic equipment judges that the data amount of the non-confidential data is determined when the transmission of the encrypted data is completed and the target forwarding data contains the non-encrypted data, then the electronic equipment judges whether the data amount is larger than the preset data amount or not, and judges that the transmission can be performed in a microwave transmission mode when the data amount is larger than the preset data amount, and then the electronic equipment generates a second microwave data instruction and sends the second microwave data instruction to the ground terminal and the target satellite, so as to control the target satellite to receive the non-confidential data in the microwave communication mode.

In some embodiments, when the electronic device determines that the data amount of the unencrypted data is not greater than the preset data amount, the electronic device indicates that the data amount of the unencrypted data is too small, and can completely continue to transmit through the laser communication mode, so that unnecessary switching of the communication mode of the target satellite can be reduced, that is, the electronic device sends the laser data forwarding instruction to the ground terminal and the target satellite again, so that the target satellite is controlled to receive the non-confidential data based on the laser communication mode.
In some embodiments, after the target satellite is controlled to receive the second communication link data set in the microwave communication mode based on the first microwave data forwarding instruction, a data forwarding instruction is generated based on the target forwarding data, and the target satellite is controlled to receive the target forwarding data in the laser communication mode or the microwave communication mode by using the data forwarding instruction.
In some embodiments, the electronic device determines a security level corresponding to the encrypted data when it determines that the forwarding of the second communication link data set is completed and the target forwarding data includes the encrypted data, where the electronic device matches the encrypted data with a preset security level to determine the security level corresponding to the encrypted data, and then compares the security level with the preset security level, and if it determines that the security level is lower than the preset level, it indicates that the security of the encrypted data is low, without considering the problem of interception during transmission, so that during transmission of the encrypted data, transmission through a microwave communication mode may be considered, 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.
In some embodiments, after the ground terminal completes the transmission of the laser communication connection data in the second communication link data, a laser communication mode verification process between the ground terminal and the target satellite is performed simultaneously with the transmission process of the ground terminal for transmitting the microwave communication connection data in the second communication link data, so as to improve the verification efficiency of the communication connection between the ground terminal and the target satellite.
