Problems solved by technology

Since the business system does not process data all the time, the computing resource utilization of the server is very low in many cases, resulting in waste of resources and energy
[0004] Therefore, each server in the existing satellite remote sensing platform has a single function and low resource utilization, and because it is a centralized storage server component, there is a single point of failure risk

Embodiment 1

[0036] figure 2 A schematic structural diagram of a satellite remote sensing cloud computing platform provided by an embodiment of the present invention is shown. Such as figure 2 As shown, the satellite remote sensing cloud computing platform includes a main control server 10, and a plurality of general servers 11 connected to the main control server 10, and one or more virtual machines 110 are all created on the general server; the virtual machine includes a storage module 111 and computing module 112. In a possible embodiment, the general server is an x86 general server.

[0037] The main control server is used to receive the satellite data downloaded by the data receiver; push the satellite data to the corresponding virtual machine according to the predefined workflow. The satellite data is the original data classified according to the order of observation. The workflow can be to write a job definition file (*.def) in a business description script language, complete ...

Embodiment 2

[0057] image 3 A schematic structural diagram of a satellite remote sensing cloud computing system provided by an embodiment of the present invention is shown. Such as image 3 As shown, the satellite remote sensing cloud computing system includes a data receiver 300, a monitoring and management platform 400, and a satellite remote sensing cloud computing platform 500 in Embodiment 1, wherein the data receiver and the monitoring and management platform are respectively connected to the main control server.

[0058] The data receiver downloads satellite monitoring data in real time, such as NPP (net primary productivity) data, reads data from the receiving buffer area, directly saves the most original remote sensing data, and extracts satellite data that needs further processing as a zero-level data product. The satellite data is sent to the satellite remote sensing cloud computing platform for analysis to realize real-time quick-view monitoring and quality statistics of NPP ...

Abstract

The invention provides a satellite remote sensing cloud computing platform and system, the satellite remote sensing cloud computing platform comprises a main control server and a plurality of universal servers connected with the main control server, and one or more virtual machines are created on each universal server; each virtual machine comprises a storage module and a calculation module; the main control server is used for receiving satellite data downloaded by the data receiver, and pushing the satellite data to a corresponding virtual machine according to a predefined workflow; the calculation module in each virtual machine is used for processing the satellite data to obtain a data product and transmitting the data product to a storage module; and the storage module in each virtual machine is used for storing satellite data as original data or storing a data product sent by the calculation module. Therefore, the same universal server can be used for calculation and storage, the resource utilization rate of the server is improved, distributed storage in a plurality of servers is realized, and the single-point fault risk is reduced.

Description

technical field [0001] The invention relates to the technical field of remote sensing satellite data processing, in particular to a satellite remote sensing cloud computing platform and system. Background technique [0002] Currently, if figure 1 As shown, the data storage server, data processing server and other business servers in the satellite remote sensing platform are all single-function and independently deployed systems. When the data receiver finishes receiving the satellite data, it will transmit the data to the storage server to save the original data, and at the same time transmit the data to the data processing server for processing. When the data server finishes processing the data and produces products, it will be transmitted to the storage The server saves, or transfers the product to other business servers for further processing as needed. [0003] Storage servers are usually deployed in a centralized storage manner to provide unified and centralized stora...
