1553B bus system for supporting spacecraft on-orbit configuration changes and control method

Abstract

The invention relates to a 1553B bus system for supporting spacecraft on-orbit configuration changes and a control method. The system includes a basic module, a cabin separation configuration change mode module, a direct grid-connection configuration change mode module and / or an indirect grid-connection configuration change mode module, wherein the basic module includes a platform 1553B bus, a platform bus controller, a platform bus terminal and a bus switch command transmitting device. According to the 1553B bus system for supporting the spacecraft on-orbit configuration changes and the control method disclosed by the invention, the problem that an existing 1553B bus system application cannot meet the dynamic reconstruction or reorganization of a data bus system by the spacecraft on-orbitconfiguration changes can be solved, and the phenomenon that the 1553B bus system can provide reliable data communication services for the platform before and after the spacecraft on-orbit configuration changes can be ensured.

Description

technical field [0001] The invention relates to the electrical field of spacecraft, in particular to a 1553B bus system and a control method for supporting configuration changes of spacecraft on orbit. Background technique [0002] The 1553B bus is a master-slave data bus that was first used in aviation and has been widely used at present. Most spacecraft usually use the 1553B bus as the platform data communication network to realize data communication between subsystems. In previous spacecraft, 1553B was used as the platform bus, and the configuration of the bus system did not change during the flight mission. [0003] With the implementation of my country's manned spaceflight engineering tasks, manned spacecraft platforms have different requirements for data communication networks than satellites. Using the 1553B bus system as the channel for the data communication network of manned spacecraft platforms must not only adapt to manned spacecraft The data communication requi...
