DETAILED DESCRIPTION

[0021] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0022] In the description of the present invention, it should be understood that “plurality” means two or more than two, unless otherwise clearly and specifically defined.

[0023] See also Figures 1 to 6The present invention provides a Beidou data transmission system including a data acquisition module 1, a data integration judgment module 2, a data segment transmission module 3, a data analysis module 4, a packaging module 5, a sending module 6 and a receiving output module 7, wherein the data integration judgment module 2 is connected to the data acquisition module 1, the data segment transmission module 3 is connected to the data integration judgment module 2, the data analysis module 4 is connected to the data segment transmission module 3, the packaging module 5 is connected to the data analysis module 4 and is connected to the data integration judgment module 2, the sending module 6 is connected to the packaging module 5, and the receiving output module 7 is connected to the sending module 6; The data acquisition module 1 is used to acquire the data to be transmitted; The data integration and judgment module 2 integrates all acquired data and performs analysis and judgment; The data segment transmission module 3 is used to segment the acquired data and then transmit it; The data analysis module 4 determines and analyzes the size of the data to be transmitted; The encapsulation module 5 encapsulates the transmitted data to form a corresponding data packet; The sending module 6 sends the encapsulated and split data through the Beidou satellite; The receiving and outputting module 7 completes the reception and output of the corresponding Beidou data.

[0024] For further information, see Figure 2 The data integration judgment module 2 includes a data integration submodule 21 and an initial judgment transmission submodule 22. The data integration submodule 21 is connected to the data acquisition module 1 and to the initial judgment transmission submodule 22. The initial judgment transmission submodule 22 is connected to the data segmentation transmission module 3 and to the encapsulation module 5. The data integration submodule 21 combines and organizes all acquired data; The initial judgment transmission submodule 22 analyzes and judges the size of the merged data, and then transmits the data accordingly according to the judgment result.

[0025] In this embodiment, first, the data to be transmitted is acquired through the data acquisition module 1, and then the acquired transmission data is sorted and merged through the data integration submodule 21, and then the size of the complete data after synthesis is analyzed according to the initial judgment transmission submodule 22. The user can limit the size of the transmission data according to the actual transmission equipment and the receiving terminal, etc., to ensure the stability of the data transmission process. When the initial judgment transmission submodule 22 detects that the total size of the synthesized data meets the specified requirements, the initial judgment transmission submodule 22 will directly transmit the integrated total data to the encapsulation module 5 for encapsulation, and then send the encapsulated data packet to the receiving output module 7 through the Beidou satellite through the sending module 6 to complete the subsequent unpacking output. When the initial judgment transmission submodule 22 detects that the total synthesized data size exceeds the specified range, the initial judgment transmission submodule 22 will transfer the data exceeding the specified range to the data segmentation transmission module 3, and then the data segmentation transmission module 3 cooperates with the data analysis module 4 to mark and segment the data, so that the synthesized large data can be separated into a specified number of small data, and then the encapsulation module 5 cooperates with the sending module 6 to transmit the marked and segmented small data, and finally the receiving and output module 7 reorganizes and unpacks the received small data to complete the output of the overall data, thereby achieving the ability to perform corresponding segmented transmission of large data with high transmission risks after analyzing and judging the data to be transmitted, thereby avoiding packet loss due to excessive transmission data and affecting the overall transmission quality.

[0026] For further information, see Figure 3 The data segment transmission module 3 includes a data marking segment submodule 31 and a transmission submodule 32. The data marking segment submodule 31 is connected to the data integration judgment module 2 and connected to the data analysis module 4. The transmission submodule 32 is connected to the data marking segment submodule 31 and connected to the data analysis module 4. The data marking and segmenting submodule 31 performs marking and segmentation on the transmitted data; The transmission submodule 32 transmits the data after the tag splitting.

[0027] For further information, see Figure 4 The data marking segmentation submodule 31 includes an identification unit 311, a marking unit 312 and a splitting unit 313. The identification unit 311 is connected to the data analysis module 4 and to the data integration judgment module 2. The marking unit 312 is connected to the identification unit 311. The splitting unit 313 is connected to the marking unit 312 and to the transmission submodule 32. The identification unit 311 analyzes and identifies whether the transmitted data carries a tag; The marking unit 312 marks the transmission data accordingly; The splitting unit 313 splits the transmission data after marking.

[0028] In this embodiment, the identification unit 311 analyzes and identifies the data input into the data segment transmission module 3 for those tags. When it is detected that the data is not marked, the marking unit 312 will perform the initial marking, and then the marked data will be split by the splitting unit 313. The splitting unit 313 can split the original data into multiple smaller data segments according to the splitting strategy set by the user, wherein each data segment should contain sufficient tag information so that the receiving end can identify which original data block it belongs to and its position in the data block. It is possible that the size of some data after splitting still exceeds the preset range in time-sharing. Therefore, in the subsequent data transmission process, the data analysis module 4 will detect the data segments after the splitting one by one. When it is detected that the size of the data segment exceeds the preset range, the data segment exceeding the range will be re-imported into the data segment transmission module 3 for secondary splitting. At this time, the identification unit 311 will identify the primary mark carried by the corresponding data segment. Therefore, when marking by the marking unit 312 later, secondary marking can be performed on the basis of the primary marking, so that when the data segments are reorganized through marking, the identification combination can be performed more quickly and accurately.

[0029] For further information, see Figure 5 The data analysis module 4 includes a data judgment submodule 41 and a data transfer submodule 42. The data judgment submodule 41 is connected to the data segment transmission module 3 and to the data transfer submodule 42. The data transfer submodule 42 is connected to the data segment transmission module 3 and to the encapsulation module 5. The data determination submodule 41 determines the size of the received transmission data; The data transfer submodule 42 transfers the data to a designated module according to the determination result of the size of the transferred data.

[0030] In this embodiment, the data size of the transmission is detected by the data judgment submodule 41. When the detected data size is within the preset range, the data transfer submodule 42 will directly transmit the data to the encapsulation module 5. When it is detected that the data size exceeds the preset range, the data transmission submodule 32 will retransmit the data back to the data segmentation transmission module 3 for re-segmentation processing to ensure that the final output data size is within the specified preset range, which greatly reduces the risk of packet loss due to excessive data during data transmission.

[0031] For further information, see Figure 6 The receiving and outputting module 7 includes a check submodule 71, a label analysis submodule 72, a recombination submodule 73 and an output submodule 74. The check submodule 71 is connected to the sending module 6, the label analysis submodule 72 is connected to the check submodule 71 and to the output submodule 74, the recombination submodule 73 is connected to the label analysis submodule 72, and the output submodule 74 is connected to the recombination submodule 73; The check submodule 71 checks the received transmission data packet; The tag analysis submodule 72 extracts and analyzes the tags carried by the data packets after verification; The reassembly submodule 73 combines and reassembles the split data packets according to the analysis results of the tags; The output submodule 74 decapsulates the data packet and converts the corresponding format to complete the output of the final complete data.

[0032] In this embodiment, the check submodule 71 mainly checks the received sub-data packets or complete data packets to ensure the integrity and accuracy of the data, wherein the check process includes data length check, check code verification, etc. When the sub-data packet or complete data packet passes the check, the tag analysis submodule 72 will perform corresponding tag analysis on the data. When no tag is detected, it means that the data packet has not been segmented by tags, so the data packet can be directly unpacked and transmitted through the output submodule 74. When the tag analysis submodule 72 detects the presence of tags in the data, it will analyze the tags in the data, and then assemble and reassemble them in sequence according to the corresponding levels of the tags, and then combine the segmented sub-data packets into a complete data packet for unpacking and transmission through the output submodule 74.

[0033] See also Figure 7 , a Beidou data transmission method, using the Beidou data transmission system, comprises the following steps: S1: The data to be transmitted is acquired through the data acquisition module 1, and then the acquired data is integrated through the data integration judgment module 2 while making a preliminary judgment on the size of the integrated data; S2: After the integrated complete data is judged by the data integration judgment module 2, it will be transmitted to the packaging module 5 and the data segment transmission module 3 respectively according to the given qualified and unqualified judgment results; S3: The qualified data entering the encapsulation module 5 will be directly transmitted and subsequently output through the sending module 6 and the receiving output module 7, while the unqualified data entering the data segment transmission module 3 will be marked and segmented in the data segment transmission module 3; S4: After the data marking segmentation is completed, it will be judged again by the data analysis module 4. If the data size after segmentation still does not meet the requirements, it will enter the data segmentation transmission module 3 again for secondary or even multiple marking segmentation. Finally, the qualified data segments after segmentation will be encapsulated and transmitted through the encapsulation module 5, the sending module 6 and the receiving output module 7, and the subsequent data segments will be reorganized and output.
