Abstract
This crane is capable of transporting cargo and includes: a feedback control unit for feedback control of the crane or an object to be controlled that is a component of the crane; a learning model that has a weighting factor and learns the characteristics of the object to be controlled in real time by adjusting the weighting factor on the basis of a teacher signal including a first signal generated by the feedback control unit; and a communication control unit that transmits the weighting factor to an external device that is communicatively connected to the crane.
Claims8
A crane capable of transporting cargo, the crane comprising:
- a feedback control unit that performs feedback control of the crane or an object to be controlled that is a component of the crane;
- a learning model that has a weighting factor and learns characteristics of the object to be controlled in real time by adjusting the weighting factor on a basis of a teacher signal including a first signal generated by the feedback control unit;
- and
- a communication control unit that transmits the weighting factor to a characteristic change determination device that determines a change in the characteristics of the object to be controlled and is communicatively connected to the crane via a network,
- wherein:
- the learning model adjusts the weighting factor on a basis of the teacher signal every time the first signal is generated in the feedback control unit;
- and
- the communication control unit transmits the weighting factor to the characteristic change determination device every time the weighting factor is adjusted in the learning model and receives a determination result concerning the change in the characteristics of the object to be controlled from the characteristic change determination device.

- a communication control unit that transmits the weighting factor to a characteristic change determination device that determines a change in the characteristics of the object to be controlled and is communicatively connected to the crane via a network;
- and
- a first storage unit for storing the weighting factor, wherein
- the first storage unit stores the weighting factor every time the weighting factor is adjusted, and
- the communication control unit acquires the weighting factor stored in the first storage unit and transmits the weighting factor to the characteristic change determination device, at a predetermined timing and receives a determination result concerning the change in the characteristics of the object to be controlled from the characteristic change determination device.
