All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In addition, the term "and/or" herein is only one kind of association relationship describing an associated object, and means that there may be three kinds of relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
All terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs unless specifically defined otherwise. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
The embodiment of the application discloses a data transmission method. A first data transmission path and a second data transmission path which are parallel are arranged in the same network environment, and when the network fluctuates in the same network environment, the same fluctuation occurs in data transmitted on the first data transmission path and the second data transmission path. Referring to fig. 1, the data transmission method includes:
s101: and receiving the communication ciphertext uploaded by the first data transmission path and the judgment plaintext uploaded by the second transmission path.
Specifically, the communication ciphertext comprises data to be transmitted, the judgment plaintext and the communication ciphertext are the same in length, when data transmission is carried out, the transmitting end simultaneously transmits the communication ciphertext through the first data transmission path, the second data transmission path transmits the judgment plaintext to the receiving end, the judgment plaintext is preset by a worker, the judgment plaintext is stored in a database of the receiving end, and each judgment plaintext carries a unique identification code.
S102: and calling the judgment plaintext carrying the identification code in the database according to the received unique identification code of the judgment plaintext.
Specifically, each judgment plaintext carries a unique identification code, after receiving a specific judgment plaintext, the receiving end sequentially reads binary data corresponding to each byte to determine the received binary data corresponding to the identification code corresponding to the judgment plaintext and the binary data corresponding to the judgment plaintext, and according to the received identification code corresponding to the judgment plaintext, the receiving end searches the judgment plaintext containing the identification code in the database. For example, judging the plaintext: when the identification code corresponding to "01101101" is "0000", when the plaintext transmission is determined, the sending end sends the determined plaintext "01101101" and the identification code "0000" corresponding thereto to the receiving end through the second data transmission path, in this embodiment, the identification code corresponds to the first byte, so that the binary data corresponding to the first byte read after the determined plaintext is received is the identification code corresponding to the determined plaintext, and after the identification code corresponding to the received determined plaintext is determined, the receiving end sequentially reads the identification codes stored in the database for determining plaintext, and determines the determined plaintext stored in the database that the determined plaintext is the same as the received identification code for determining plaintext.
Further, after the first byte data is read, the identification code cannot be determined, a stop instruction is output at this time, the subsequent communication ciphertext is stopped being acquired, and the acquisition instruction is simultaneously output to the sending end, the sending end receives the acquisition instruction to resend the communication ciphertext sent simultaneously with the judgment plaintext and simultaneously send the judgment plaintext, the corresponding relation between the plaintext and the communication ciphertext is judged to be absent, and the plaintext is judged to be only used for judging whether the received communication ciphertext is correct or not.
S103: and comparing the judgment plaintext carrying the identification code in the database with the received judgment plaintext carrying the identification code, and outputting a comparison result.
Specifically, after finding the judgment plaintext carrying the identification code in the database, determining binary data corresponding to the judgment plaintext, and comparing the binary data with the received binary data corresponding to the judgment plaintext in sequence according to a preset comparison sequence, in this embodiment, the comparison sequence is to compare the binary data from the first binary data in sequence, and when the received binary data corresponding to the judgment plaintext is the same as the binary data corresponding to the judgment plaintext stored in the data storage and the digits corresponding to the same digits are the same, judging that the received judgment plaintext is the same as the judgment plaintext stored in the database; when the binary data corresponding to the received judgment plaintext is different from the binary data corresponding to the same judgment plaintext stored in the data storage or the digits corresponding to the same digits, the received judgment plaintext is judged to be different from the judgment plaintext stored in the database, namely, the data transmission error is caused by the fluctuation of the network environment at the moment, and the same error also occurs in the transmission of the corresponding communication ciphertext.
S104: and judging whether the communication ciphertext needs to be acquired again or not based on the comparison result.
Specifically, the received judgment plaintext is the same as the judgment plaintext stored in the database, and at this time, the communication ciphertext does not need to be acquired again. And when the communication ciphertext does not need to be acquired again, the system works normally.
S105: if yes, outputting a first data acquisition instruction to acquire the communication ciphertext again based on the comparison result.
Specifically, when it is determined that the communication ciphertext needs to be obtained again, a first data obtaining instruction is output based on the comparison result, for example: the received judgment plaintext is: the corresponding judgment plaintext stored in the 001101010111 database is "0011010101110100", and the data is determined to be missing, and the missing target binary data is "0100", which is transmitted by two parallel data transmission paths in the same network environment, and the length of the communication ciphertext and the length of the judgment plaintext are the same, so that the communication ciphertext has data missing, the timestamp information corresponding to the target binary data is acquired, the receiving end outputs a first data acquisition instruction to the transmitting end, and the receiving end retransmits the binary data in the communication ciphertext corresponding to the timestamp information according to the timestamp information corresponding to the target binary data after receiving the first data acquisition instruction; the received judgment plaintext is: the corresponding judgment plaintext stored in the 001101010111 database is 001101010101, and the data is judged to be a data error at this moment, and the wrong binary data is 10111, so that the timestamp information corresponding to the wrong data is determined, the receiving end outputs a first data acquisition instruction, and the sending end receives the first data acquisition instruction and retransmits the binary data in the communication plaintext corresponding to the timestamp information to the receiving end. In other embodiments, when a data transmission error occurs, all data of the communication ciphertext can be directly acquired again.
It can be understood that, since data transmission is sequential transmission and when decrypting the currently acquired communication ciphertext, the communication plaintext after the previous decryption needs to be used, when data transmission is performed, the situation that the entire communication ciphertext is lost may cause a current ciphertext decryption error, and in order to solve the problem, after the step S101 is executed, the method further includes: the method comprises the steps of obtaining timestamp information of a communication ciphertext sent by a sending end and timestamp information of a received communication ciphertext, when data transmission is carried out, the timestamp information of the communication ciphertext sent by the sending end at present is the same as the timestamp information from a current receiving end to the received communication ciphertext, when the timestamp information of the communication ciphertext sent by the sending end at present is different from the timestamp information from the current receiving end to the received communication ciphertext, stopping receiving subsequent communication ciphertext by a receiving end, deleting the currently received communication ciphertext, outputting a second data acquisition instruction, receiving the second data acquisition instruction by the sending end, resending the communication ciphertext needing to be sent at present to the receiving end, and continuing to obtain the subsequent communication ciphertext when the receiving end judges that the currently received communication ciphertext is correct.
