Abstract

The invention discloses a high-reliability satellite-borne software architecture design method based on an operating system, adopts a multi-process + multi-thread development mode to carry out a comprehensive electronic system software development process, and can ensure unattended satellites that operate in a complex electromagnetic environment , the long-term on-orbit operation is stable. Even in the event of a failure, normal operation can be restored by means of the corresponding measures in the method. The purpose is to make the spaceborne integrated electronic computer use the embedded operating system, not only can play the advantages of the spaceborne embedded operating system, but also uphold the reliability of the traditional spaceborne integrated electronic system. Aiming at the integrated electronic system software based on the embedded operating system, the present invention, while adhering to the mature reliability measures of the traditional on-board software, can also utilize the advantages and convenience provided by the operating system to further enhance the scalability of the on-board integrated electronic system and reliability, thereby improving the reliability and maintainability of the entire star.

Description

technical field [0001] The invention relates to the technical field of on-board embedded software, in particular to a high-reliability on-board software architecture design method based on an operating system. 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 stream, the increase in the number of payloads means that the complexity of the integrated electronic system software increases. Based on the traditional on-board software development model, continuing to develop the integrated electronic system software in the current satellite and aircraft systems will face many problems, such as difficulty in software upgrade and expansion, inconspicuous software layering, inability to decouple software and hardware, and low software utilization. . ...
