Elevator landing control system

A position adjusting module included in an elevator, comprising:

• a connecting rope connecting an upper frame to which a main rope is connected and a cage;
• a rotating gear provided in contact with the connecting rope;
• and
• a driver configured to apply a rotational force to the rotating gear,
• wherein the connecting rope is provided to form two columns between the upper frame and the cage, and
• when the rotating gear is rotated, positional compensation is performed on the cage through crossing between the two columns of the connecting rope.

A method of controlling landing of an elevator, comprising:

• acquiring a landing error related to a step difference between a cage and a floor through a sensor device;
• acquiring tilt detection information related to whether the cage has been tilted to a specific region through a tilt measuring device;
• and
• controlling a position adjusting device based on the landing error and the tilt detection information,
• wherein the position adjusting device includes a plurality of position adjusting modules provided between the cage and an upper frame provided with a main rope connected thereto, and
• each of the plurality of position adjusting modules includes a connecting rope connecting the upper frame and the cage, a rotating gear provided in contact with the connecting rope, and a driver configured to apply a rotational force to the rotating gear.
