Title:
CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/033765
Kind Code:
A1
Abstract:
Provided is a control device capable of achieving low power consumption even when the wire temperature is erroneously calculated.
A control unit (64) calculates the temperature difference between the ambient temperature of a wire (4a) (or wire (4b)) and the temperature of the wire (4a) (or wire (4b)) with time and supplies or interrupts the current flowing through each of the wires (4a, 4b). When the temperature sum of the calculated temperature difference and ambient temperature is a first threshold value or more, the control unit (64) interrupts the current flowing through each of the wires (4a, 4b). The control unit (64) also times the period during which the current is interrupted. For each of the wires (4a, 4b), when the calculated temperature difference is less than a second threshold value or the timed period exceeds a predetermined period, the control unit (64) halts the calculation of the temperature of the wires (4a, 4b).
