LED-ID Door lock device using the visible light communication system based on LED-ID technology

摘要

The present invention relates to a door lock device using a visible light communication (VLC)-based LED-ID technique, and more specifically, to a door lock device using a VLC-based LED-ID technique which can automatically open and close a door lock through optical camera communication (OCC) and VLC by using light emitted by a flash or an LED and a display mounted in a conventional smartphone. The door lock device using a VLC-based LED-ID technique according to the present invention has the advantages of: preventing the leakage of a password, a password error, and the like due to a contact method of entering, in a touch manner, a preset password on a keypad provided on a digital door lock by applying OCC and VLC communication methods; being resistant to external optical noise; and solving a security problem such as hacking. Further, the door lock device of the present invention can be used in a hotel, an unmanned hotel, private locker rooms of a fitness center, and the like, as well as in a family home, thereby eliminating the requirement of an information desk and a resident workforce.
