Abstract: Provided is a machine state detecting device capable of easily detecting the state of a machine, regardless of whether an unknown operation that is not expected to cause damage is performed. A state detecting device 100 includes a collection device 1a that collects, at a plurality of times, state information if indicating the state of the machine that changes chronologically, and an arithmetic processing device 1b that processes a plurality of pieces of the state information if collected at the plurality of times to detect the state of the machine.

Abstract: A vehicle body management system for managing a vehicle body having a power train formed by a plurality of parts including a prime mover, the vehicle body management system including: a processing device that computes an efficiency value of a monitoring target, the monitoring target being the power train or a part or a subsystem of the power train, on the basis of information about the vehicle body, the information being sensed by a sensor provided to the vehicle body; and an output terminal that outputs the efficiency value of the monitoring target, the efficiency value being computed by the processing device, the processing device computing a load parameter of the power train, determining whether the load parameter is larger than a load determination value set in advance, computing the efficiency value of the monitoring target on the basis of input energy and output energy of the monitoring target on condition that the load parameter be larger than the load determination value, and recording the computed ef

Abstract: An action recognition system includes a controller that computes, in a time division manner, a plurality of feature vectors using as feature quantities information of a machine with respect to running that varies in a time sequence, generates a classification model by classifying the feature vectors into a plurality of clusters and allocating identification IDs to the clusters, generates an ID pattern model by allocating the identification IDs to the feature vectors computed in the time division manner on the basis of the classification model and associating a pattern of the identification IDs that vary in a time sequence according to a predetermined action of the machine with identification information of the predetermined action, generates output information for recognizing the predetermined action on the basis of changes in the identification IDs in the time sequence and the ID pattern model, and controls the display device to output the output information.

Abstract: An object of the invention of the present application is to provide a mine management system capable of accurately maintaining and managing the productivity of a mine.
