Abstract

The invention relates to the communication field, and discloses a transmitting and receiving device based on visible light communication, and a method thereof. The device comprises a transmitting part and a receiving part, wherein the receiving part comprises a photoelectric detector which is used for receiving a visible light signal. The receiving part also comprises an alignment module which is used for detecting the light intensity information of the received visible light signal, judging a position with the strongest intensity, and controlling the alignment direction of a receiving end of the photoelectric detector according to the position with the strongest intensity. When the device is used for receiving the visible light signal, the device can automatically align the position of a signal source, speeds up the alignment, achieves automatic control, saves manpower and time, fully collects the visible light signal, and improves the effectiveness of the signal.

Description

technical field [0001] The present invention relates to the field of communication, in particular to a transceiver device and method based on visible light communication. Background technique [0002] As a new model combining lighting and optical communication, LED visible light communication promotes the development and technological progress of next-generation lighting and access networks, and has become the focus and commanding heights of competition at home and abroad. Visible light communication technology came into being along with the development of LED lighting (also known as solid-state lighting) technology, which can enable LED lights to perform high-speed communication while lighting. [0003] At present, visible light communication technology is mainly concentrated in the mining and commercial fields, and the volume is relatively large. The existing farthest center transmission distance is about 4m, and the receiving end and the transmitting end need to be aligne...
