What follows is whether there is a difference before and after data transmission, which directly reflects the transmission quality of the communication network system. The quality of data transmission directly affects the correctness of data information after transmission, and is also the key to improving the transmission capacity of communication networks. In the process of communication network transmission, the factor that most easily affects the quality of data transmission is the garbled characters that appear during transmission. Therefore, it is of great theoretical and practical significance to accurately identify whether there is garbled characters after data transmission, locate the position of garbled characters, and take measures to correct them to improve the quality of data transmission in communication networks; How to compare the changes before and after transmission according to the changes of data symbols during data transmission, determine whether there is an error, and correct the error is the problem we need to solve. To this end, a communication network data transmission system is now provided. Summary of the invention

If so, it indicates that the data stream has garbled codes. If there are no non-binary code elements, it indicates that the data stream is normal. When the data stream is normal, obtain a data stream sub-segment of 7 consecutive binary code elements, obtain the first 4 binary code elements as information code elements, and obtain the last 3 binary code elements as supervision code elements. The interactive platform includes a network layer, a transport layer and an application layer, the obtained data stream sub-segments are sequentially transmitted in the network layer and the application layer, and the transmitted data stream sub-segments are reprocessed by the transport layer in the interactive platform; Obtain the information codewords in the data stream sub-segment, determine the destination of the interactive data according to the obtained information codewords, generate a data transmission command according to the obtained destination, select the corresponding data transmission link in the transport layer according to the generated data transmission command, and pass the data stream sub-segment to the transport layer.

It should be further explained that, in a specific implementation process, when the number of binary code elements corresponding to the last data stream sub-segment is less than 7, a reverse complement is performed on it; the reverse complement means that when the number of binary code elements corresponding to the last data stream sub-segment is less than 7, zeros are padded in front of the data stream sub-segment until the number of binary code elements is 7; For example: The data flow segment corresponding to the data content segment is recorded as 100010101001110110001001011; Then the obtained data stream sub-segments are 1000101, 0100111, 0110001, 0001011;

The process of the network signal monitoring module monitoring the transmission start node and end node is as follows: When the network signal monitoring module detects a signal anomaly at the start node, it will interrupt operation, retain the data information before the signal interruption, and continue to run from the interruption point after the signal is restored, until all the processed data flow sub-segments pass through the start node; The process of the start node reprocessing the data stream sub-segment includes: Get the data stream sub-segment of the information sending end, and mark the binary code elements of the data stream sub-segment as i=1, 2, 3, 4, 5, 6, 7 in sequence, where i=1, i=2, i=3, i=4 are recorded as information code elements, and i=5, i=6, i=7 are recorded as supervision code elements; The data stream sub-segments are grouped into three groups to form a 3×7 matrix, denoted as matrix H, and multiple 3×7 matrices H can be formed; It should be further explained that, in a specific implementation process, the data stream sub-segments of the data stream are grouped into groups of three, and when there are any remaining data stream sub-segments, they are reversely grouped; the reverse grouping means that when there are any remaining data stream sub-segments after the data stream sub-segments are grouped into groups of three, the remaining data stream sub-segments are recombined with the previous data stream sub-segments to form a 3×7 matrix H again; For example: The data flow segment corresponding to the data content segment is recorded as 10001010100111011000100010111100101; Then the obtained data stream sub-segments are 1000101, 0100111, 0110001, 0001011, 1100101;

Add the rows of the matrix H modulo 2 to convert the obtained matrix I into a 3×3 unit matrix, and record the changed matrix H as matrix H. 1 ; For example: Let the matrix H be , then the changed matrix H 1 for ; When the network signal monitoring module detects an abnormal signal at the end node, it interrupts the operation; it should be further explained that in the specific implementation process, after the interruption of the operation, when the matrix H is obtained 1 When the signal is restored, the transmitted data stream is retransmitted. When the matrix S is obtained, the signal is restored and then the operation is continued from the interrupted position until all the processed data stream sub-segments pass through the end node. The process of the end node reprocessing the transmitted data stream sub-segment includes: Get the data stream sub-segments of the information receiving end, and mark them as a=1, 2, 3, 4, 5, 6, 7, recorded as a 1×7 matrix A, then the multiple data stream sub-segment codeword sequences can be recorded as A1, A2, A3..., An, n is an integer; The above matrix An and matrix H 1 The transpose of is multiplied and modulo 2 is added to obtain a 1×3 matrix, which is denoted as matrix S. Then the matrix S is expressed as S=An·H 1 T ; The state of the matrix S is as follows: When the matrix S is a zero matrix, there is no error in the transmission of this sequence, that is, no bit error occurs; When the matrix S is a non-zero matrix, it means that the received data stream sub-segment codeword transmission is erroneous. According to the obtained matrix S codeword sequence, it is matched with the codeword comparison table, and the error code positions are marked one by one according to the matching results; It should be further explained that, in the specific implementation process, the relationship between the S matrix and the error code position is as follows:
