Assignee: MITSUBISHI ELECTRIC CORPORATION
Field: Handling (Mechanical engineering)
Classification: CPC B  G | IPC B  G

Claim 17:
18. A work determination apparatus comprising:
a sensor data output circuit to output state data with an output interval of an integral multiple of a control period with which a motion of an industrial machine is controlled, the state data representing a state of work of the industrial machine;
a determination circuit to determine a quality of the work of the industrial machine with the output interval for the state data by making an inference using a recurrent neural network with the output interval for the state data, based on the state data outputted from the sensor data output circuit; and
a motion correction circuit to perform control so as to correct the motion of the industrial machine based on a result of determination of the determination circuit, wherein
the determination circuit further determines a type of anomaly in the work, and calculates a value representing an amount of misalignment of the industrial machine, and
when the value representing the amount of misalignment is less than a specified value, the motion correction circuit performs control such that the motion of the industrial machine is not corrected in the work concerned, but the motion of the industrial machine is corrected in the next work of the industrial machine with use of the value representing the amount of misalignment so as to prevent misalignment.
