自动门开启动作
Automatic door opening action
当人靠近 自动门时， 设置于门内外侧的检测装置（垫开关、红外线开关、光线开关等）将其检测出来，之后，信号送到控制装置。控制装置接到该信号后驱动马达向门的开启方向—马达的旋转带动减速器、皮带轮、皮带或链条，使门向开启方向运动。当门接近门挡通过开启制动位置时，制动力作用于马达，门减速，其速度变为徐行速度，行至门挡位置后停止。
When a person is near the automatic door, the detection device (pad switch, infrared switch, light switch, etc.) set on the inside and outside of the door detects it, and then the signal is sent to the control device. The control device receives the signal and drives the motor to open the door - the rotation of the motor drives the reducer, the pulley, the belt or the chain, so that the door moves in the open direction. When the door approaches the opening braking position, the braking force acts on the motor, and the door decelerates. The speed changes to creep speed, and stops when the door reaches the opening braking position.
