VISIBLE LIGHT TRANSMITTER AND IN-OUT DOOR LOCATION RECOGNITION SYSTEM AND METHOD USING THE SAME

摘要

A visible light transmitting apparatus and a system and method for recognizing indoor and outdoor locations using the same are disclosed. A visible light transmitting apparatus according to an embodiment of the present invention and a system and method for recognizing an indoor/outdoor location using the same include a plurality of visible light transmitting devices for transmitting visible light signals, and a visible light receiving device for receiving visible light signals transmitted by the plurality of visible light transmitting devices. An indoor/outdoor location recognition system including, by dividing a time unit into preset intervals to set a plurality of transmission times, setting a reference visible light transmission device to one of the plurality of visible light transmission devices to allocate a transmission time, and A time allocating unit allocating different transmission times between the transmitting device and adjacent visible light transmitting devices, a signal synchronizing unit synchronizing the time unit, a control unit generating a digital signal in a time slot allocated to the synchronized time unit, and the digital A visible light transmitting device including a light emitting unit for converting a signal into a visible light signal and transmitting it; And a visible light receiving device for receiving the visible light signal from the visible light transmitting device, converting the received visible light signal into a digital signal to extract a unique ID, and outputting a location corresponding to the extracted unique ID to the outside. .
