摘要: A state data acquisition unit acquires state data indicating a state of a work machine at a plurality of times. A work determination unit 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 unit determines a start point and an end point of a period related to a predetermined classification among determined classifications of works. An index-value determination unit obtains an index value of the state of the work machine from the start point to the end point.

摘要: A transmission system includes a transmission, first and second composite sensors, and a controller. The transmission has a clutch switchable between an engaged state and a disengaged state, a first shaft disposed on an input side of the clutch, and a second shaft disposed on an output side of the clutch. The first and second composite sensors detect rotation speeds and rotation phases of the first and second shafts, respectively. The controller acquires a load torque applied to the transmission. When the clutch is switched from the disengaged state to the engaged state, the controller derives a phase difference between the rotation phase of the first shaft detected by the first composite sensor and the rotation phase of the second shaft detected by the second composite sensor based on the time when the clutch has stopped slipping. The controller acquires the load torque based on the derived phase difference.
