A Remote Sensing Satellite Integrated Electronic System Based on Bus Routing

Abstract

A remote sensing satellite integrated electronic system based on bus routing, comprising: a control module, a routing module, a computing module, a storage module, and a modulation and adaptation module. As a high-speed data channel, the routing bus realizes the interconnection among modules such as computing, storage, modulation and adaptation, and the internal data flow of the system is flexible and controllable. Computing, storage and other modules adopt ring backup design, there is no fixed corresponding relationship, and the single boards between modules can be combined and communicated arbitrarily. The computing module adopts a high-performance computing platform, cooperates with the storage module to complete the on-orbit intelligent processing of high-speed payload data, and supports software on-orbit injection, task replacement and expansion. The above-mentioned integrated electronics solves the problem that the integrated electronic data flow direction of the remote sensing satellite data processing and transmission system is fixed, 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.
