Abstract

The invention relates to a combined spacecraft data processing method based on hierarchical routing. The method comprises the steps: a, transmitting the uplink injection data and downlink telemetry data of a plurality of spacecraft cabins between each spacecraft cabin and the ground through spacecraft identifiers, virtual channels and data domain three-layer identifiers in a VCDU frame; b, periodically interacting data between the spacecraft cabins and in each spacecraft cabin through an application progress identifier APID and an auxiliary guide head in the EPDU packet to realize periodic interaction of cross-cabin and cross-subsystem data; c, realizing interaction instructions between different spacecrafts in the combined spacecraft and between different stand-alone devices on the spacecraft through the spacecraft identifiers and the virtual channel two-layer identifiers in the subpackage remote control frames according to the accidental interaction data between the spacecraft cabinsand in each spacecraft cabin. According to the method provided by the invention, standardization and autonomy of on-device data processing can be realized, so a system has good expansibility.

Description

technical field [0001] The invention relates to a combined spacecraft data processing method based on hierarchical routing. Background technique [0002] The information management system is an important part of the spacecraft. It is generally composed of a data management subsystem (or star affairs management subsystem) and a measurement and control data transmission subsystem. Digital communication. [0003] At present, the existing spacecraft mainly use the traditional PCM format and the AOS format for data framing and coding communication. The formats of data exchanged between different devices or aircrafts are different, and the formats of different space-ground links are different. In spacecrafts that fly independently or in short-term combined flights, the traditional design can meet the requirements due to the small scale of the system itself and the simple dynamic combination mode. [0004] However, in a large combined spacecraft, the traditional design is not ver...
