Operation monitoring device and a control program therefor
An operation monitoring device includes an analytical data obtaining unit for obtaining analytical data that contain history information of a machine; a non-operation reason analysis unit for analyzing the state of the machine by classifying the state of the machine for every predetermined time as either of an operating state and a plurality of kinds of non-operating states, based on the analytical data, the operating state being a state in which the machine is operating, and the non-operating states being classified based on a reason for non-operation; a storage unit for storing an analysis result storage database that stores the result of analysis; a display unit for presenting to a user the result of the analysis; and a correction unit for correcting the result of the analysis according to an instruction from the user.
1. An operation monitoring device for managing a state of a machine tool, comprising:
a storage unit;
an output unit for outputting information to a user;
an input unit for receiving an operation from the user; and
a control unit,
wherein
the control unit:
obtains analytical data that contain history information on the machine tool,
analyzes the state of the machine tool, for a predetermined time, by classifying the state of the machine tool as an operating state or at least one non-operating state of a plurality of kinds of non-operating states, based on the analytical data, such that the operating state is a state in which the machine tool is operating, and the non-operating states are classified based on a reason for non-operation,
stores a result of analysis in an analysis result storage database of the storage unit,
presents the result of analysis stored in the storage unit to the user via the output unit, and
corrects the result of the analysis stored in the storage unit according to an instruction inputted from the user via an input unit.
2. The operation monitoring device according to claim 1 , wherein
the control unit determines, for the analysis, one or more candidates for the state of the machine tool and a probability of-each of the candidates for a predetermined time, and presents the one or more candidates for the state of the machine tool to the user as correction candidates for the result of the analysis in order of a higher probability of the candidate.
3. The operation monitoring device according to claim 1 , wherein
the storage unit stores a result of the analysis before correction and a result of the analysis after the correction, and
the output unit presents to the user both the result of the analysis before the correction and the result of the analysis after the correction.
4. The operation monitoring device according to claim 1 , wherein
the storage unit additionally stores an analytical parameter file that stores information to which reference is made for the analysis, and
the control unit analyzes the state of the machine tool with reference to the analytical parameter file.
5. The operation monitoring device according to claim 4 , wherein
the control unit corrects the analytical parameter file in accordance with a content of correction to the result of the analysis.
