Abstract

The invention relates to a space laboratory information system based on an advanced in-orbit data processing method. The telemetering, instruction and communication functions are realized through a data information system based on a 1553B bus, and the high-speed data transmission is realized through a high-speed data transmission system based on AOS. The space laboratory information system based on the advanced in-orbit data processing method disclosed by the invention can support a manned spacecraft to accomplish all in-orbit functions.

Description

technical field [0001] The invention relates to the electrical field of spacecraft, relates to the design of a manned spacecraft information system, in particular to a manned spacecraft information system based on an advanced on-orbit data processing method. Background technique [0002] With the continuous development of space technology, the scientific tasks of spacecraft flight are becoming more and more heavy, and the amount of data is increasing. The TG-1 space laboratory has many types of data sources, a large amount of bus data, and multiple output channels, which are reflected in: [0003] 1) The data transmitted by the space laboratory includes engineering telemetry, digital tube telemetry, video and voice, scientific experiment data, and application system data. [0004] 2) The data sources of the space laboratory include 2 sets of 1553B bus with a total of 26 terminals, 1 set of docking 1553B bus with a total of 2 terminals, and 1 set of 1394 bus with a total of 5...
