摘要： The present disclosure provides a fatigue management system capable of managing fatigue of each portion of a construction machine more accurately than conventional systems. The fatigue management system S includes: a stress calculation section S1 that calculates stress acting on a plurality of portions of the construction machine based on the output of a sensor 18 attached to a part of the construction machine; a damage degree calculation section S2 that calculates the cumulative damage degree of each portion of the construction machine based on the stress calculated by the stress calculation section S1; and an index value calculation section S3 that calculates a fatigue index value, which is a weighted value of the cumulative damage degree, for each portion.

摘要： Provided is a movement identification device capable of identifying a specific motion of a construction machine based on the output of a sensor attached to the construction machine with higher accuracy than the conventional technology. A movement identification device 100 includes a waveform generation unit 111, a waveform storage unit 121, and a motion identification unit 112. The waveform generation unit 111 generates a force waveform based on the signal of a force sensor that detects the force acting on the construction machine and an attitude waveform based on the signal of an attitude sensor that detects the attitude of the construction machine. The waveform storage unit 121 stores reference waveforms, which are combinations of force waveforms and attitude waveforms corresponding to specific motions. The motion identification unit 112 compares a motion waveform, which is a combination of a force waveform and an attitude waveform corresponding to an arbitrary motion of a construction machine, with the reference waveforms stored in the waveform storage unit 121 to identify a specific motion in the arbitrary motion of the construction machine.

摘要： A working machine, equipped with a working device (7) that extends to the outside of a machine body (1), includes: a physical quantity detection sensor (15, 25, 31, 33, 35, 36, 37, 38, 39) that detects a physical quantity concerning the working machine; a monitor (43) that displays predetermined information (61, 63); and a controller (51) that controls the monitor. The controller includes a stress calculation section (53) that calculates a distribution (63a) of stress applied to the working device based on the physical quantity concerning the working machine, detected by the physical quantity detection sensor, and a display control section (57) that controls the display of the predetermined information on the monitor. The display control section controls the display on the monitor so as to indicate the distribution of the stress applied to the working device, calculated by the stress calculation section, in conjunction with the movement of the working device.
