DOOR CONTROL DEVICE AND ELEVATOR DEVICE
Document Type and Number:
Japanese Patent JP2018184244
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To address the problem that a passenger in a car and a passenger at a landing site cannot safely move a door to move baggage pulled in through the door.SOLUTION: A door overload monitoring door provided on this door control device switches a door moving mode to a manual mode when application of an overload on a door is detected on the basis of the control result of the door driven by a door driving device. A manual-time torque command generation unit stops the door by outputting a torque command which corresponds to a torque value balanced with a mechanical door closing force based on a door moving amount detected by a moving amount detection unit provided on the door driving device. The manual-time torque command generation unit outputs a torque command which compensates for the torque value in accordance with a direction where the door is manually moved. A motor current control calculation unit outputs a control value of a motor current calculated on the basis of the torque command input from the manual-time torque command generation unit to the door driving device.SELECTED DRAWING: Figure 1
