Abstract

A diagnosis system and a diagnosis method of a construction machine which enable even a user who has little knowledge about procedures or techniques for diagnosing construction machines to speedily diagnose a construction machine to be diagnosed in a manner suited to the data characteristics of the machine. The diagnosis device (10) acquires diagnosis data from a diagnosis data storage device (30), extracts the data characteristics from the information contained in the diagnosis data, acquires from a diagnosis knowledge storage device (20) diagnosis techniques considered to be effective for the data characteristics, and presents the techniques to the user along with the degree of effectiveness. Then, the user selects a diagnosis technique using the degree of effectiveness and diagnoses the construction machine. Moreover, in order to make the most use of the knowledge about diagnosis stored in the diagnosis knowledge storage device (20), a diagnosis knowledge generation unit (107) classifies common data characteristics by each element of the diagnosis techniques, and stores the classified data characteristics and the elements of the diagnosis techniques as new diagnosis 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...
