Diagnosis system and diagnosis method of construction machine

Abstract

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.

Description

technical field [0001] The present invention relates to a system and method for diagnosing the state of a construction machine. More specifically, it relates to a system and method for diagnosing a construction machine that can be used even by users who have little knowledge of procedures and techniques for diagnosing the state In other words, it is also possible to perform effective diagnosis according to the diagnosis target data. Background technique [0002] In the case of diagnosing the state of a machine using a plurality of sensor data provided on the machine, an optimum result cannot be obtained only by directly inputting the sensor data into a diagnostic program. In order to obtain the best results, various steps such as selection of sensor data used for diagnosis, preprocessing of sensor data, selection of diagnosis method, and setting of parameters used in the diagnosis method need to be properly carried out. implement. Also, even if the device to be diagnosed i...

AI Technical Summary

Problems solved by technology

[0007] The technology of storing and presenting the combination of product characteristics and the number of past failures to the user is a technology aimed at support at the time of design, and cannot be applied to the diagnosis of the state of construction machinery

In addition, in the technique of presenting an analysis method based on the purpose of data analysis, when there are a plurality of analysis methods corresponding to the purpose of analysis, the user must select an appropriate analysis method, so there may be a problem depending on the user. The amount of knowledge to choose the analysis method that is not optimal and the time required to obtain the correct analysis results increase
