Embodiment 1

[0050] According to an embodiment of the present invention, a method for processing multi-source remote sensing big data based on Chord ring is provided, see figure 1 , including the following steps:

[0051] S100: Build a system architecture based on the Chord ring. The system architecture is composed of multiple subsystems, each subsystem has an independent task submission site, and each subsystem is located in a data center; each subsystem has an external interface and has a routing table for query routing;

[0052] S200: Divide a task submitted from a subsystem of a data center and send it to a subsystem of another data center for processing.

[0053] In the multi-source remote sensing big data processing method based on the Chord ring in the embodiment of the present invention, each data center serves as a node of the Chord ring, has an external interface, and has a routing table to perform query routing work. Each data center has a certain degree of independence, has i...

Embodiment 2

[0111] According to another embodiment of the present invention, a multi-source remote sensing big data processing device based on Chord ring is provided, see Figure 6 ,include:

[0112] The system architecture construction unit 201 is used to construct the system architecture based on the Chord ring, the system architecture is composed of multiple subsystems, each subsystem has an independent task submission site, and each subsystem is located in a data center; each subsystem has an external Interface, and has a routing table to perform query routing work;

[0113] The task processing unit 202 is configured to divide a task submitted from a subsystem of a data center and then send it to a subsystem of another data center for processing.

Abstract

The invention relates to the field of remote sensing big data, in particular to a multi-source remote sensing big data processing method and device based on a Chord ring. According to the multi-sourceremote sensing big data processing method and device, each data center is used as a node of a Chord ring, is provided with an external interface and is provided with a routing table for inquiring routing work. Each data center has certain independence, has an independent task submission site, and can access data of other data centers at the same time. And a plurality of data centers form a Chordring logically. The multi-source remote sensing big data processing method has good transverse expansion capability, can thoroughly solve the migration problem of the remote sensing data while realizing data sharing, and can realize calculation sharing of the remote sensing data.

Description

technical field [0001] The invention relates to the field of remote sensing big data, in particular to a Chord ring-based multi-source remote sensing big data processing method and device. Background technique [0002] With the rapid development of computers, digital sensors, network communication technology, aviation satellites and other technologies, human beings have entered the era of big data, which provides favorable support for human industrial production decision-making and business model change. Remote sensing is one of the most important sources of big data. Agricultural remote sensing big data plays an important role in indicating agricultural production activities such as farmland monitoring, irrigation planning, and disaster warning. However, the special data format and huge data volume of agricultural remote sensing big data give Its application poses challenges. At present, many research institutions at home and abroad have been committed to the storage, calc...
