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

Claim 12:
13. 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; and
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, wherein
the output interval is L times the control period, where L is an integer equal to or greater than 2,
sensor data is inputted to the sensor data output circuit for each control period, the sensor data being a result of detecting the state of the work of the industrial machine, and
the sensor data output circuit outputs, as the state data, an average value of the latest L pieces of the sensor data.
