The present invention discloses a platform door intelligent control device, including a power supply module, a controller, a motor drive and a motor connected in sequence, and also including a platform door controlled to be switched on and off by said motor, a Hall sensor for feeding back motor current signals, and a tachometer for feeding back motor rotational speed signals, and said Hall sensor, and the tachometer are electrically connected between said controller and said motor respectively, and said The controller automatically realizes the control of the platform door through the feedback current change and the speed change of the motor speed; said platform door intelligent control device is set at the entrance and exit of the train door, corresponding to the upward and downward sides of the track; said platform door intelligent control device is set a number of times along the length of the subway platform and is electrically connected to the central monitoring and controlling panel through a bus. The said intelligent control device is capable of making different closing responses to different resistance, solving the problem that the platform door cannot be closed normally under dynamic wind pressure, and improving the operation efficiency of the subway.
