Reconfigurable satellite integrated electronic system

Abstract

The invention discloses a reconfigurable satellite integrated electronic system, which can realize fast reconfiguration of the system, improves fault-tolerant capability of the system, reduces power consumption and weight of the whole satellite and reduces waste of calculating resources. The system comprises more than two integrated service units and a 1553B bus. The more than two integrated service units are connected through the 1553B bus; one of the integrated service units serves as a bus controller BC of the 1553B bus, and the other integrated service units serve as remote terminals RT ofthe 1553B bus. The BC is configured to execute an integrated control task of on-satellite in-orbit data; one RT is configured to execute one on-satellite independent electronic function task; and when the current BC fails, one RT is switched to a new BC of the 1553B bus, and the new BC executes the integrated control task of the on-satellite in-orbit data.

Description

technical field [0001] The invention relates to the technical field of satellite electronic systems, and specifically designs a reconfigurable satellite integrated electronic system. Background technique [0002] The satellite integrated electronic system is an information processing and transmission system that interconnects on-board electronic equipment to realize satellite internal information sharing and comprehensive utilization, function integration, and resource reorganization optimization. It is one of the five major platform systems that are juxtaposed with structure and mechanism system. [0003] As a complete system with certain functions and composed of software and hardware resources, the satellite integrated electronic system is an integrated system composed of a variety of different functional modules. Under the unified task scheduling and management, it can complete all the management functions of the entire satellite. Including data management, attitude and...

Problems solved by technology

The central management unit and the comprehensive business unit have a clear division of labor and cannot replace each other; each unit has a stand-alone cold backup or a stand-alone hot backup, with low fault tolerance

[0005] In the above-mentioned satellite integrated electronic system, the backup stand-alone needs to participate in the system operation in real time, and only when the central management unit fails, the backup stand-alone is switched to work, which results in an increase in power consumption and weight of the entire star and a waste of computing resources
