Abstract:In order to solve the current problem of maintenance and condition monitoring for complex equipment, research on information fusion health monitoring of complex equipment has been proposed. Study of complex equipment health monitoring requirements is carried out, and the meaning of health monitoring research for complex equipment is clear. The conception of equipment health monitoring is completed, and the significance of introducing information fusion technology to complex equipment health monitoring is analyzed. The status at home and abroad of information fusion technology research is analyzed. Aiming at the data level, feature level and decision level of information fusion technology, the typical information fusion algorithms for all levels are mainly analyzed. And a good foundation of further research of information fusion health monitoring for complex equipment has been laid.
