Abstract

The invention discloses a satellite-borne information processing system, method and device and a readable storage medium, and belongs to the field of satellite-borne platform management and load datamanagement. The satellite-borne information processing system which is high in flexibility and high in flexibility and has dynamic assembly characteristics is constructed on the basis of a flexibly-changed system architecture and remote control of a bus conversion module. The satellite-borne information processing system has the characteristic of stretchability, distribution of all processing nodes can be stretched in the most suitable form according to the requirements of the system, the requirements of the system are met, meanwhile, in the stretching process, software configuration of the system does not need to be changed, an electronic system can still keep the stability of circuit connection, and the reliability of the system is improved; therefore, the system can be widely applied tosatellite platforms and load management.

Description

technical field [0001] The invention belongs to the field of on-board platform management and load data management, and relates to an on-board information processing system, method, equipment and readable storage medium. Background technique [0002] The on-board information processing system needs to process the telemetry and remote control data of the whole star, monitor the operating status of the platform and load of the whole star, distribute and collect the telemetry data, and realize the power-on / off control of the load and platform equipment, etc. [0003] Due to the different sizes of the spacecraft cabins, the distribution of each payload and platform equipment in the entire satellite cabin is different for each satellite, and the resources that the payloads and platform equipment themselves need to manage are also different, which requires on-board information processing. The system needs to be customized according to the volume of the satellite cabin, the load an...
