Research on Software Architecture of Prognostics and Health Management System for Civil Aircraft

Prognostics and Health Management has been applied to detect and diagnose device faults and assess its health status, with aiming to enhance device reliability, safety, and reduce its maintenance costs. Software architecture is the key to implement prognostics and health Management ground support system successfully. On the basis of research on typical PHM software architectures, a software architecture based on SOA and Dual bus technology is proposed to share the information and ensure the flight safety. And the prognostics and health management system for civil aircrafts based on SOA and dual bus is developed, which is being successfully used in a certain type of native civil aircraft. The practical application result shows the system could provide services for civil aircraft and run in multi-platform and distributed computing environments.
