Patent ID: 11905685
Assignee: KOMATSU LTD.
Field: Control (Instruments)
Classification: CPC E  G | IPC E  G

Claim 0:
1. An index-value determination device comprising:
a work machine;
a state data acquisition processor unit that acquires state data indicating a state of the work machine at a plurality of times;
a work determination processor unit that determines a classification of a work of the work machine for each of the plurality of times based on the acquired state data;
a period determination processor unit that determines a start point and an end point of a period related to a predetermined classification among determined classifications of works; and
an index-value determination processor unit that obtains an index value of the state of the work machine, the index value of the state of the work machine including at least a swing angle of the work machine from the start point to the end point,
wherein the work determination processor unit acquires a likelihood of each classification of the work of the work machine based on the acquired state data, and determines the classification of the work of the work machine for each of the plurality of times based on the likelihood of each classification of the work,
the index-value determination device further comprises a smoothing processor unit which performs a smoothing process of the likelihood of each classification of the work acquired by the work determination processor unit, and
the period determination processor unit determines the start point and the end point of the period related to the predetermined classification among the determined classifications of the works based on the likelihood in which the smoothing process is performed.
