The invention relates to an intelligent safety elevator based on speed detection. The intelligent safety elevator comprises a dragging steel wire rope, a speed detector and an air bag control center. The dragging steel wire rope is used for dragging a car of the elevator. The speed detector is connected with the dragging steel wire rope and used for determining the elevating speed of the car according to changes of the dragging length of the dragging steel wire rope. The air bag control center is connected with the speed detector and used for determining whether an air bag inside the car needs to be opened on the basis of the elevating speed. By means of the intelligent safety elevator, the air bag in the car can be automatically opened so to protect personnel in the car of the elevator on the condition that the elevating speed of the elevator is abnormal.
