Embodiment 1

[0037] A multi-level data storage system in a network source coordination online monitoring system includes a link communication module, a protocol processing module, and a dynamic data storage module. In view of the fact that the front-end and back-end message processing mechanisms adopted by the conventional front-end are difficult to meet the performance requirements of high-density and large-capacity dynamic data collection, this system uses shared memory-based, distributed asynchronous high-speed data processing in the link communication module The scheme implements dynamic data parsing and stores it in the pre-data buffer area for raw data monitoring. The whole process takes less than 2 milliseconds to complete. The protocol processing module processes the data in the pre-data buffer area and stores it in the dynamic data buffer area for online evaluation and analysis. The dynamic data storage module further processes the data in the dynamic data cache area and stores th...

Embodiment 2

[0048] A multi-level data storage method in a network source coordination online monitoring system is implemented based on a multi-level data storage system in a network source coordination online monitoring system in Embodiment 1, including:

[0049] Obtain the upload information of the online monitoring device;

[0050] Perform dynamic data analysis on the uploaded information and store it in the pre-data buffer area;

[0051] After the data in the pre-data buffer area is reduced, it is stored in the dynamic data buffer area;

[0052] Store the data in the dynamic data buffer to the time series database and relational database.

Embodiment 3

[0054] The embodiment of the present invention also provides a multi-level data storage device in the network source coordination online monitoring system, which can realize the multi-level data storage method in the network source coordination online monitoring system in the second embodiment, including a processor and a storage medium;

[0055] The storage medium is used to store instructions;

[0056] The processor is configured to operate according to the instructions to perform the steps of the following method:

[0057] Obtain the upload information of the online monitoring device;

[0058] Perform dynamic data analysis on the uploaded information and store it in the pre-data buffer area;

[0059] After the data in the pre-data buffer area is reduced, it is stored in the dynamic data buffer area;

[0060] Store the data in the dynamic data buffer to the time series database and relational database.
