[0005] 2. Realize resource sharing between different regions: When the aircraft structure PHM system requires ground maintenance personnel to carry out maintenance tasks, the required resources may not be available. At this time, maintenance personnel need to call resources in other fields through other channels in time. The PHM system of stand-alone aircraft structure does not have the ability to allocate resources efficiently and quickly

The invention discloses a cluster-level airplane structure prognostic and health management (PHM) system. An airplane structure PHM wide-area intelligent information service platform server comprises a resource organization, resource share, decision support and knowledge base and is interconnected with distributed airplane structure PHM field resources, a system supplier, a researcher and a generalized knowledge base respectively through a wide area network; singlechip structure PHM systems of airplanes in different types are connected with sub terminals of a wide-area intelligent information service platform through a local area network or the wide area network to realize information and resource sharing in a cluster; the sub terminals of the wide-area intelligent information service platforms of a plurality of clusters are interconnected with the airplane structure PHM wide-area intelligent information service platform server through the wide area network to realize information and resource sharing; and professionals and software and hardware resources in different professional fields are also interconnected with the airplane structure PHM wide-area intelligent information service platform server through the wide area network to share the knowledge, the technologies and the resources with all the clusters.
Description
technical field [0001] The invention relates to a fleet-level aircraft structure PHM system, which is used for fleet-level aircraft structure prediction and health management. Background technique [0002] Aircraft is a complex mechanical system with high value and maintenance costs. Aircraft failures and accidents often cause varying degrees of economic losses and social impacts, and maintenance costs account for a large proportion of the cost of aircraft service. The application of aircraft health monitoring and management can realize the online or offline status monitoring of the aircraft system, timely forecast the potential failures of the system, reduce system accidents, improve the safety of system operation, and perform maintenance according to the actual status of the system. This reduces maintenance costs. Therefore, the health monitoring and management technology of aircraft is of great significance. It has important application value for preventing major acciden...
