specific Embodiment approach 1

[0019] Specific implementation mode one: see figure 1 Describe this embodiment, a spacecraft bus router based on component modules described in this embodiment, the bus router includes a bus registration management module and an intermediate component data exchange module, and the bus router communicates with N components to communicate, N is a positive integer,

[0020] The bus registration management module is used to manage the spacecraft bus registration, extract the bus component theme, manage the bus component communication mapping table according to the bus component theme, and register the intermediate component;

[0021] The intermediate component data exchange module includes multiple intermediate components for realizing data exchange between intermediate components.

specific Embodiment approach 2

[0022] Embodiment 2: The difference between this embodiment and the component-based module-based spacecraft bus router described in Embodiment 1 is that the bus registration management module is used to manage spacecraft bus registration and extract bus components Topic, according to the topic of the bus component to manage the component communication mapping table between buses, the specific process of registering the intermediate component is as follows:

[0023] The spacecraft software bus registers the bus with the bus registration management module, and the bus router extracts the component address of the spacecraft software bus,

[0024] According to the bus component address of the spacecraft software, the bus router searches the topic of the bus component. When a component needs to communicate with other bus components, it inserts the communication component into the mapping table and registers the intermediate component.

specific Embodiment approach 3

[0025] Embodiment 3: The difference between this embodiment and the component-based module-based spacecraft bus router described in Embodiment 1 is that the intermediate component data exchange module includes a plurality of intermediate components for realizing The specific process of data exchange is:

[0026] Wait for the component communication time slot between buses, look up the bus router component mapping table according to the component topic,

[0027] If there is no corresponding bus router component mapping entry, then end this communication;

[0028] Otherwise, according to the component theme, the component to be communicated is sent to the bus where the component to be communicated is located, and the intermediate component corresponding to the component to be communicated in the bus router component mapping table exchanges data with another intermediate component, and the The other intermediate component sends data to another bus other than the bus where the co...

Abstract

A spacecraft bus router based on component modules, relating to a spacecraft bus router. It solves the problem of low communication efficiency caused by the difficulty of communication between buses caused by the coexistence of multiple buses in the existing spacecraft. The bus router includes a bus registration management module and an intermediate component data exchange module, and the bus router communicates with N components through multiple buses, N is a positive integer, and the bus registration management module is used to manage the spacecraft bus registration, extract The bus component theme manages the component communication mapping table between buses according to the bus component theme, and registers the intermediate components; the intermediate component data exchange module includes multiple intermediate components for realizing data exchange between intermediate components. It is mainly used in information communication in the field of spacecraft.

Description

technical field [0001] The invention relates to a spacecraft bus router. Background technique [0002] At present, in order to improve the versatility, the upper management of the spacecraft adopts component technology, and the components are connected through software buses. In order to better play the advantages of component generalization, the spacecraft adopts multiple software buses. Due to the coexistence of multiple buses in spacecraft, it is difficult to communicate between buses. Contents of the invention [0003] The invention aims to solve the problem of low communication efficiency caused by communication difficulties between buses caused by the coexistence of multiple buses in the existing spacecraft. The invention provides a spacecraft bus router based on componentized modules. [0004] A spacecraft bus router based on componentized modules, the bus router includes a bus registration management module and an intermediate component data exchange module, and ...
