LEFT HANDED AND RIGHT HANDED CONVERT CONTROL METHOD AND APPARATUS OF DIGITAL DOOR LOCK

摘要

PURPOSE: A method for controlling the left handed and right handed change of a digital door lock and an apparatus thereof are provided to be conveniently switched and used for a left hand door and a right-handed door. CONSTITUTION: An indoor unit and an outdoor unit are fixed to both sides of a bracket. The bracket is closely connected to and fixed in a cross section of a glass door. Two LEDs separately driven are installed inside a button of a key input unit in an outdoor unit. A character window, in which two different characters are printed, is formed in two LED right upward directions. A microcontroller(400) is built in the outdoor unit. The microcontroller connects a turn-on/off driver(403). The turn-on/off driver turns on one selected from the two LED installed at each button of the key input unit by the control of a selection device which is connected with additional microcontrollers.
