Embodiment Construction
[0065] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0066] Frame: It is the smallest unit of a single video frame in video animation, which is equivalent to each frame on a movie film. One frame is a still picture, and the continuous frames form animation, such as TV images. The frame in this article refers to the data formed at a specified output moment in the hydrodynamic model.
[0067] Document database: It can store and obtain documents, and its format can be XML, JSON, BSON, etc. These documents are self-describing and present a hierarchical tree data structure (hierarchical tree data structure), which can contain mapping tables , collections, and scalar values. Documents in a database are similar to each other, but not necessarily identical. The documents stored in the document database are equivalent ...

The invention relates to a water conservancy data fragmentation storage method, an on-demand method and a processing system, and the method comprises the steps: S1, carrying out the extraction processing of a result file of a hydrodynamic model received by a first client through taking a frame as a unit, and obtaining first structural data corresponding to each frame of the result file of the hydrodynamic model; wherein each frame of the hydrodynamic model result file has a frame number; wherein the plurality of node data are longitudinally arranged in sequence according to a node numbering sequence; S2, performing recombination processing on the first structured data to obtain second structured data; S3, performing compression processing on the second structured data to obtain bson structure data; wherein the bson structure data comprises a label for identifying a frame number of a two-dimensional hydrodynamic model result file corresponding to the bson structure data; and S4, storing the bson structure data into a document database in communication connection with the first client.
Description
technical field [0001] The invention relates to the technical field of data storage, in particular to a water conservancy data slice storage method, an on-demand method, and a processing system. Background technique [0002] For the storage and retrieval of existing water conservancy data, there are many water conservancy models in the water conservancy data and the corresponding result files are very large, occupying a large space. For example, the result file of the 2D hydrodynamic model is relatively large, and the data storage capacity of a large scene will reach the level of hundreds of gigabytes. [0003] The current water conservancy data needs to be aggregated together, and each water conservancy department can retrieve the water conservancy data of each region in real time or periodically for research and determine a reasonable scheduling plan. Based on this, in the prior art, each water conservancy model and its corresponding result files are uploaded to the cloud...
