Title:
MACHINE PERFORMANCE DIAGNOSIS APPARATUS, AND CONSTRUCTION MACHINE DIAGNOSIS SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/249097
Kind Code:
A1
Abstract:
The present disclosure proposes a machine performance diagnosis apparatus that diagnoses the soundness of an operation of a construction machine to reduce the possibility that a human error will occur and to obtain a more accurate diagnosis result, the machine performance diagnosis apparatus comprising: a storage device that stores reference waveform data for each of a plurality of operations of the construction machine, and a performance reference value and an allowable error value for each of the plurality of operations; and a processor that executes a process for diagnosing the soundness of the construction machine. The processor executes: a process for identifying an operation which was actually executed by comparing sensor waveform data obtained by sensing, with a sensor, an operation which was actually executed by the construction machine with the reference waveform data retained in the storage device; and a process for obtaining, from the storage device, the performance reference value and the allowable error value corresponding to the identified operation, and comparing the obtained performance reference value and the allowable error value with a characteristic value of the operation which was actually executed to determine the soundness of the construction machine.
