CONVEYANCE ABNORMALITY DETECTING DEVICE AND CONVEYANCE ABNORMALITY DETECTING METHOD AS WELL AS METHOD FOR CONSTRUCTING MAXIMUM CURRENT PREDICTION MODEL FOR DETECTING CONVEYANCE ABNORMALITY

Japanese Patent JP2023130912

A

To enable a conveyance abnormality of a material of steel plates to be detected surely at low cost.SOLUTION: A conveyance abnormality detecting device detects a conveyance abnormality of a material of steel plates. The conveyance abnormality detecting device comprises: an obtaining part that obtains actual values of driving currents distributed respectively to a plurality of driving motors which drive a plurality of conveyance rollers that convey the material of steel plates; and a determining part that inputs a material specification parameter concerning the material of steel plates and operational parameters concerning a conveyance speed and acceleration of the material of steel plates as well as an injection quantity of cooling water, and outputs actual values of the driving currents distributed to the plurality of driving motors respectively, and determines whether or not a conveyance abnormality occurs in the material of steel plates, on the basis of a learnt maximum driving current prediction model to which machine learning is performed so that the maximum value of the driving currents is predicted in accordance with prescribed machine learning algorithm, the maximum value of the driving currents predicted by the learnt maximum driving current prediction model and the actual values of the driving currents obtained by the obtaining part.SELECTED DRAWING: Figure 3
