Abstract
A system for estimating an abnormality includes an industrial device that controls one or more jigs such that the one or more jigs press an object to perform a work process, and processing circuitry that acquires operation data that is related to an operation of the industrial device and is measured at multiple time points after the object is pressed by the one or more jigs, and perform an estimation estimating an abnormality based on the operation data acquired.
Claims20
A system for estimating an abnormality, comprising:
- an industrial device configured to control at least one jig such that the at least one jig presses an object to perform a work process;
- a torque data acquisition sensor configured to acquire torque data of torque of a motor configured to move the jig;
- a position data acquisition sensor configured to acquire position data on a position of the jig;
- and
- processing circuitry configured to detect that the jig is separated from the object based on the torque data and perform an estimation estimating an abnormality based on the position data, the position data being acquired based on detection that the jig is separated from the object,
- wherein the torque data includes a torque measurement at a time point when the jig starts to separate from the object, wherein the processing circuitry is configured to estimate the abnormality based on the torque measurement.
A method for estimating abnormality, comprising:
- controlling a jig by an industrial device such that the jig presses an object to perform a work process;
- acquiring torque data of torque of a motor configured to move the jig using a torque data acquisition sensor;
- acquiring position data on a position of the jig using a position data acquisition sensor;
- detecting that the jig is separated from the object based on the torque data;
- and
- estimating an abnormality based on the position data, the position data being acquired based on detection that the jig is separated from the object,
- wherein the torque data includes a torque measurement at a time point when the jig starts to separate from the object, wherein the estimating includes estimating the abnormality based on the torque measurement.
A non-transitory computer-readable storage medium including computer executable instructions, wherein the instructions, when executed by a computer, cause the computer to perform a method, the method comprising:
- controlling a jig by an industrial device such that the jig presses an object to perform work process;
- acquiring torque data of torque of a motor configured to move the jig using a torque data acquisition sensor;
- acquiring position data on a position of the jig using a position data acquisition sensor;
- detecting that the jig is separated from the object based on the torque data;
- and
- estimating an abnormality based on the position data, the position data being acquired based on detection that the jig is separated from the object,
- wherein the torque data includes a torque measurement at a time point when the jig starts to separate from the object, wherein the estimating includes estimating the abnormality based on the torque measurement.
