PROBLEM TO BE SOLVED: To smoothly open/close a door even at strong wind time by setting output torque of a motor for opening/closing the door to a value corresponding to wind force. SOLUTION: This opening/closing control device for an automatic door has a door 1 and a motor 4 for opening/closing the doorway, and also has a door opening/closing operation part 8, an automatic door controller 12 for normally rotating, reversely rotating and stopping the motor 4 and a wind force sensor 9 for inputting wind force to the automatic door controller 12 by detecting the wind force near the door 1. The automatic door controller 12 sets output torque of the motor 4 to a value corresponding to the inputted wind force. Thus, at light wind time when moving resistance of the door 1 by wind pressure is small, motor output torque is small, so that door opening/closing force becomes a small value corresponding to the door moving resistance, and at strong wind time when the door moving resistance by the wind pressure is large, the motor output torque is large, so that the door opening/closing force becomes a large value corresponding to the door moving resistance. Thus, even when a strong wind acts on the door, the door can be smoothly opened/ closed. |
