Problems solved by technology

[0003] The existing processing method is to delete the wrong data when the data is wrong, and re-request the data source to send the data, but for many data sinks, such as the data sink in the neural network, once the data is delivered, it may affect the data sink. The data set in is polluted, even if the wrong data is deleted, it will have an irreversible impact on the data sink, resulting in final data deviation

Embodiment approach

[0053] As an implementation manner, extracting the first feature information of the source data includes:

[0054] Get the file size of the source data;

[0055] Calculate the distance of preset data clusters in the source data.

[0056] By presetting a data cluster, the data cluster can be any continuous data combination that appears more than once in the source data, and when the number of occurrences is large, the average or histogram distribution of each distance can also be calculated.

[0057] As an implementation manner, extracting the second feature information of the delivery data includes:

[0058] Get the file size of the delivered data;

[0059] Calculate the distance of the preset data clusters in the delivered data.

[0060] By extracting the above-mentioned first feature information and second feature information, it is possible to quickly and accurately determine whether there is a difference between the source data and the delivered data, that is, whether t...

Abstract

The invention discloses a data transmission error processing method and system. By creating a shadow copy for a data set of a data sink, adding a time stamp when the source data is sent, all changes in the data set in the target data sink after the time stamp are recorded. Denoted as data change, by extracting the first feature information of the source data and the second feature information of the delivered data, the first feature information and the second feature information are compared, and when the second feature information does not match the first feature information, The data set is restored to the timestamp node according to the data change. When an error occurs in data transmission, the shadow copy can be used to restore the data set of the data sink, which effectively prevents the data sink from being polluted or the input of wrong data caused by data transmission errors. The irreversible problem caused by the data sink ensures the integrity and correctness of the data sink.

Description

technical field [0001] The present invention relates to the technical field of data transmission, in particular to a data transmission error processing method and system. Background technique [0002] Data transmission is the communication process in which data is transmitted from the data source to the data sink. According to the order of data transmission, it can be divided into parallel transmission and serial transmission. According to the synchronization method, it can be divided into synchronous transmission and asynchronous transmission. Data transmission errors may occur due to external interference, signal distortion and signal distortion; [0003] The existing processing method is to delete the erroneous data in the event of a data error, and re-request the data source to send data. Even if the wrong data is deleted, it will have an irreversible impact on the data sink, resulting in the final data deviation. SUMMARY OF THE INVENTION [0004] In view of this, th...
