[0108] The partition frequency setting includes: setting different synchronization frequencies for the first data stream set stored in the first cloud partition, the second data stream set stored in the second cloud partition, and the third data stream set stored in the third cloud partition, and recording their respective synchronization frequencies as f1, f2, and f3, wherein f1<f2<f3;

[0109] It should be noted that the third data stream set is composed of several chaotic spectrum data streams, and the first data stream set is composed of several stable spectrum data streams. When performing subsequent information synchronization, the higher the value of the synchronization frequency, the faster the synchronization rate will be, and the smaller the impact of unstable factors in the synchronization process will be. The instability of the chaotic spectrum data stream is stronger than that of the stable spectrum data stream, so it requires a higher synchronization frequency. Therefore, the synchronization frequency of the third data stream set is higher than that of the first data stream set, and the stability of the second data stream set is between the first data stream set and the third data stream set. Therefore, the synchronization frequency of the second data stream set is also between the synchronization frequencies of the above two.

[0110] The content of the partition information summary is: the first data stream set stored in the first partition of the cloud is synchronized according to the synchronization frequency f1, and the corresponding first synchronization information set is generated; the second data stream set stored in the second partition of the cloud is synchronized according to the synchronization frequency f2, and the corresponding second synchronization information set is generated; the third data stream set stored in the third partition of the cloud is synchronized according to the synchronization frequency f3, and the corresponding third synchronization information set is generated; the first synchronization information set, the second synchronization information set and the third synchronization information set are merged to generate the corresponding nuclear power equipment information set, and the nuclear power equipment information set is backed up and sent to the administrator.

[0111] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
