Automatic door opening control system and method according to rotation trend of door body

Abstract

The invention discloses an automatic door opening control system and method according to the rotation trend of a door body, and relates to the field of intelligent refrigerator control. The automaticdoor opening control system involves a driving mechanism, a door body angle detection module, a motor current detection module and a motor control module; the driving mechanism is used for driving a gear to rotate, and the door body angle detection module is used for judging whether the door body is opened in place or not or closed in place or not and judging the rotation trend of the door body according to the detected rotation angle of the door body; and the motor current detection module is used for monitoring the current magnitude of a motor and judging whether the door body is blocked ornot or the rotation of the door body is manually suspended or not according to the current magnitude, and the motor control module is used for controlling the rotation of the motor. According to the automatic door opening control system and method according to the rotation trend of the door body, the door opening and closing trend of a user is judged through the angle change of the gear of the refrigerator door body, and the motor control module controls the gear to continue to rotate in the gear rotating direction, so that user operation is facilitated, and the intelligent experience of the user is improved.

Description

technical field [0001] The invention belongs to the field of intelligent refrigerator control, and in particular relates to a control system and method for automatically opening a door according to the rotation trend of the door body.
