Embodiment Construction

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0043]It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0044] In addition, in th...

Abstract

The invention discloses an open and universal intelligent satellite software system architecture which realizes rapid design and manufacturing of satellites and is beneficial for the satellites to realize inter-satellite resource sharing. The lowest layer of the architecture is a hardware resource of a satellite, and the upward first layer is an operating system layer. On one hand, the operating system abstracts and encapsulates underlying resources to realize container-based lightweight resource blurring; meanwhile, files, energy, safety and the like of the satellite are managed, and a universal service interface is provided upwards. Secondly, a container engine layer is arranged in the middle, resources are efficiently managed on the basis of an operating system, and services such as load balancing, service discovery and resource limitation are provided for application software on the upper layer; and finally, the uppermost layer of the software is an application software layer of the satellite. Software and related libraries required by running of the software are packaged into mirror images on the layer, and resource allocation and service at the application software level canbe achieved based on a container engine. The architecture has a wide application prospect in software system design and software development of intelligent satellites.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to an open and general intelligent satellite software architecture. Background technique [0002] Compared with general software, the number of satellite software systems is relatively dense, the configuration items are many and complex, and most of them operate under harsh conditions or high-speed conditions. Generally, they deal with automatic operation status, and local failures can easily cause global collapse. Therefore, the importance of software It goes without saying that the status is relatively high. The software architecture of the present invention refers to the satellite on-board software architecture. [0003] A common software architecture helps improve cost and planning predictability, improve mission-critical software quality, reduce software defect rates during testing and operations, increase software development productivity, and promote software reuse. Sinc...
