摘要

Provided is a construction machine diagnosing system and method in which even a user who has little knowledge of any procedures and techniques for diagnosing construction machines can speedily diagnose a desired machine in a manner appropriate for particular data characteristics of the machine. A diagnosis device 10 acquires diagnostic data from a diagnostic data storage device 30, extracts data characteristics from the information contained in the diagnostic data, acquires from a diagnostic knowledge storage device 20 any diagnosing techniques considered to be effective for the data characteristics, and presents to a user the diagnosing techniques along with respective degrees of effectiveness. The user uses the presented degrees of effectiveness to select a desired diagnosing technique and conduct a diagnosis. In addition, in order to make effective use of the diagnostic knowledge stored within the diagnostic knowledge storage device 20, a diagnostic knowledge generating section 107 classifies common data characteristics by elements of diagnosing techniques and stores the classified data characteristics and the elements of the diagnosing techniques, as new diagnostic knowledge.
