Study on The Application of Health Management Techniques in Aerospace Testing Software

Recently, health management (HM) techniques have been widely applied in mechanical equipment and electronic systems. They have made important contributions to improve the system reliability and reduce maintenance cost. Limited work, however, has been done on HM techniques for software systems, especially for aerospace software. Based on the study of the characteristics of the HM, the concept of software health management (SHM) is formally defined and the hierarchical structure is divided, and the software health management concept is introduced to the aerospace testing software. The features of the aerospace testing software is analyzed and summarized by the example of "The digital rocket-ground signal detection and analysis system", then the design principles of health management system for aerospace testing software are studied and the overall framework is designed. The results of this paper have a certain significance for HM techniques used in software field, especially in the field of space testing software.
