Remote sensing satellite integrated electronic system based on bus route

Abstract

A remote sensing satellite integrated electronic system based on a bus route comprises a control module, a routing module, a calculation module, a storage module and a modulation adaptation module. The routing bus serves as a high-speed data channel to achieve mutual communication among modules of calculation, storage, modulation adaptation and the like, and the flow direction of data in the system is flexible and controllable. Ring backup design is adopted for calculation, storage and other modules, a fixed corresponding use relation does not exist, and single boards among the modules can berandomly combined for communication. The calculation module adopts a high-performance calculation platform, is matched with the storage module to complete on-orbit intelligent processing of high-speedload data, and supports software on-orbit annotation, task replacement and expansion. The integrated electronics solve the problems that the integrated electronic data flow direction of a remote sensing satellite data processing and transmission system is fixed, and the function is simple and cannot be changed.

Description

technical field [0001] The invention provides a remote sensing satellite integrated electronic system based on bus routing, which relates to the field of remote sensing satellite data processing and transmission. Background technique [0002] With the continuous improvement of the resolution of remote sensing satellites, the amount of remote sensing image data has increased sharply, resulting in more payload data interfaces, and the demand for hardware resources of back-end data processing equipment has expanded. However, this contradicts the development trend of today's space system integration and miniaturization. Integrated electronic equipment is an integrated equipment that includes multiple functional modules. As a data processing system with certain functions, it perfectly solves this contradiction. [0003] The existing integrated electronic design mainly simply integrates data processing and transmission equipment into a single machine, including data compression m...

AI Technical Summary

Problems solved by technology

[0003] The existing integrated electronic design mainly simply integrates data processing and transmission equipment into a single machine, including data compression module, data storage module, encoding module, control module, and power supply module. The hardware connection relationship between the master and backup is fixed and cannot be crossed, and the data flow between the boards is single. If there is a problem with one module of the master or backup, the entire data processing link cannot be used, which greatly reduces the reliability of the system.
