Title:
SYSTEM FOR SUPPORTING DETERMINATION OF ABNORMALITY OF MOVING OBJECT
Document Type and Number:
WIPO Patent Application WO/2011/118290
Kind Code:
A1
Abstract:
Provided is a system for supporting the determination of abnormality of a moving object, which improves the operation rate by appropriately predicting the possibility of abnormality from a failure generated when the moving object experiences a failure and by reducing erroneous detection. A moving object (101) of the system for supporting the determination of abnormality of a moving object comprises: various types of measurement devices (103); a status monitoring device (104) for detecting whether a failure has occurred by using status data from the measurement devices; and a communication device (107) for transmitting failure information to a ground system (102) and receiving an abnormality determination result from the ground system. The ground system (102) comprises: a communication device (114) for transmitting and receiving data to and from the moving object; a storage unit (111) for storing past failure information; an abnormality determination unit (112) for analyzing and determining whether or not a past failure is abnormal; an abnormality analysis database (113) for storing the past failure information in association with abnormality diagnosis results; and an abnormality occurrence prediction unit (115) for contrasting the failure information from the time of occurrence of the failure in question and the abnormality analysis database (113), and outputting an abnormality determination result.
