High-reliability satellite-borne software architecture design method based on operating system

Abstract

The invention discloses a high-reliability satellite-borne software architecture design method based on an operating system, which adopts a multi-process and multi-thread development mode to carry outa comprehensive electronic system software development process, can ensure unattended operation, can run on a satellite in a complex electromagnetic environment, and is stable in long-term on-orbit running. Even if a fault occurs, normal operation can be recovered through corresponding measures in the method. After the satellite-borne integrated electronic computer uses the embedded operating system, the advantages of the satellite-borne embedded operating system can be exerted, and the reliability of a traditional satellite-borne integrated electronic system can be maintained. Aiming at theintegrated electronic system software based on the embedded operating system, the advantages and convenience provided by the operating system can be utilized to further enhance the expandability and reliability of the satellite-borne integrated electronic system while the mature reliability measures of the traditional satellite-borne software are maintained, so that the reliability and maintainability of the whole satellite are improved.

Description

technical field [0001] The invention relates to the technical field of on-board embedded software, in particular to an operating system-based high-reliability on-board software architecture design method. Background technique [0002] With the mission requirements of satellites and aircraft, the number and functions of payloads are on the rise. Compared with the integrated electronic system software, which is responsible for the processing and communication of the entire satellite data flow, the increase in the number of payloads means that the complexity of the integrated electronic system software has increased. Based on the traditional on-board software development model, if we continue to develop the integrated electronic system software in the current satellite and aircraft systems, we will face many problems, such as software upgrade and expansion are difficult to achieve, software layering is not obvious, software and hardware cannot be decoupled, and software utilizat...
