Document Type and Number:
WIPO Patent Application WO/2020/196954
Kind Code:
A1
Abstract:
The present invention relates to an apparatus for determining whether a heater is abnormal by using power consumption and a method therefor. The method for determining whether a heater is abnormal by using power consumption, according to the present invention, comprises the steps of: reading hourly power consumption according to changes in temperature of the heater; calculating an abnormality index value by using a difference between predefined power consumption reference data for each temperature of the heater and data of the read power consumption; determining whether the heater is abnormal and a degree of abnormality by using the abnormality index value; and, if it is determined that the heater is abnormal, issuing a warning at a level corresponding to the degree of abnormality. As such, according to the present invention, in a heat treatment manufacturing process, it is possible to determine early whether a heater is abnormal by reading power consumption according to changes in temperature of the heater, and thus, there are effects of reducing a defect rate of parts resulting when the heater is abnormal, and reducing the loss of time and manufacturing costs.
