Hyperspectral data simulation and application platform based on distribution assembly

Abstract

A hyperspectral data simulation and application platform based on a distribution assembly includes that 1 integrating a dispatching control central assembly and an upper layer application assembly in an assembly mode to a unified platform and finishing management control of each assembly; 2 adopting a distribution assembly dynamic integration mechanism and providing flexible setting of working states and methods on a system from a dispatching control center; 3 adopting a synchronous control technology between assemblies, providing a synchronous mechanism which is highly reliable and capable of monitoring in real time through sub-satellite point information, and achieving data synchronization between a satellite track and posture, data simulation and data application and processing; and 4 adopting a three-layer application network communication mechanism in the dispatching control central assembly to obtain safe and stable transmission of communication data. The hyperspectral data simulation and application platform has high expandability and stability, each assembly runs independently, free increase and decrease of application assemblies are achieved through dynamic expansion of the assemblies, and the hyperspectral data simulation and application platform can be applied to hyperspectral data simulation and application processing flexibly.

Problems solved by technology

[0005] CORBA is a tightly coupled distributed solution, which is slightly insufficient in ease of use. It needs to be supported and controlled by an additional software library when using it. It is required that each node participating in communication and computing must load specific software on its own machine. software

At the same time, CORBA is only a technical specification, and the products of each company are not exactly the same. There are a large number of command sets that must be familiarized with, and there is a lack of efficient development tools to build component products.

[0006] Web Service technology is a loosely coupled distributed solution based on the B / S interface. Its goal is to build a platform-independent and language-independent general technology layer. However, due to too many service provision links, it makes low efficiency
