The invention relates to data processing, in particular to a remote sensing satellite big data processing method and system based on edge computing, a transmission node selects acquisition terminals in a coverage area to form a transmission cluster, and the acquisition terminals determine the size of each sub-transmission cluster and report the size to the transmission node; the transmission node determines data terminals in the sub-transmission clusters corresponding to the acquisition terminals, and the data terminals send data to the transmission node through the acquisition terminals; obtaining the task load of the edge node in a preset interval time period, and obtaining a classification feature graph based on a series of task loads of the edge node; performing global average pooling on the feature matrix of each channel of the classification feature map to obtain a feature vector, and obtaining a classification feature vector based on the feature vector; inputting the classification feature vector into a classifier to obtain the working state of the edge node; according to the technical scheme provided by the invention, the defect that the requirement of a user on high timeliness of data processing cannot be met in the prior art can be effectively overcome.
Description
technical field [0001] The invention relates to data processing, in particular to a remote sensing satellite big data processing method and system based on edge computing. Background technique [0002] With the rapid development of satellite remote sensing, remote sensing satellite data has gradually shown a trend of operational application in land, forestry and other fields. However, the current remote sensing satellite data processing system is based on the existing technological development level and is oriented to meet user needs. It has not yet adapted to the remote sensing satellite big data that has the characteristics of "3V (Volume, Variety, Velocity)" and cannot be processed by conventional means. Analysis and Design. [0003] With the reduction of hardware costs, the improvement of network bandwidth, the rise of distributed computing, the development of network technology, the rise and application of intelligent terminals and the Internet of Things, the space-tim...
