Abstract

The present invention includes, a failure sensing part to sense the failure created in the encoder mode and sensorless mode to control the door; a main control part to convert the main operation part and backup control part mutually when a failure is sensed by the primary operation mode by the failure sensing part after deciding either of the encoder mode or sensorless mode as a primary operation mode and another one is decided as a backup operation mode; and a location/speed conversion part to perform the door control by calculating the door moving distance according to the corresponding mode when the operation mode is converted by the main control part.

Claims (16)

1. A dual control method for door comprising

a first performance stage performing door control by deciding either of an encoder mode or a sensorless mode as a primary operation mode to control the door;

a transforming stage converting the said primary operation mode to another mode when a failure is sensed in said primary operation mode; and

a second performing stage controlling the door by calculating a door moving distance depending on the converted primary operation mode,

wherein the door moving distance is calculated using number of pulses from motor and screw pitch in case of said primary operation mode is the encoder mode in said first and second performing stages, and the door moving distance is calculated by using angular velocity of the motor and screw pitch in case of said primary mode is the encoder mode.

2. The dual control method for door according to claim 1 ,

wherein performing the encoder mode and the sensorless mode concurrently regardless of deciding said primary operation mode in said first performing stage.

3. The dual control method for door according to claim 1 ,

wherein said transforming stage includes an informing stage informing an information for the failure creation to the external device.

4. A dual control method for door comprising

a first performance stage for performing door control by deciding an encoder mode as a primary operation mode to control the door;

a switching stage for converting the primary operation mode to sensorless mode when the failure is sensed in the encoder mode decided; and

a second performing stage for controlling the door by calculating a door moving distance depending on the switched sensorless mode using a screw pitch adapted to the encoder mode,

wherein calculating a door moving distance using number of motor pulse and screw pitch in the first performance stage, and a calculating a door moving distance using a angular velocity of motor and screw pitch in the second performance stage.

5. The dual control method for door according to claim 4 ,

wherein the switching stage includes an informing stage informing an information for the failure creation to the external device.
