Title:
VISIBLE LIGHT POSITIONING ASSISTED MULTI-USER LIGHT COMMUNICATION SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/040228
Kind Code:
A1
Abstract:
A visible light positioning assisted multi-user light communication system and method. The communication system comprises a micro base station and a user receiver (400); the micro base station comprises a mounting plate (100), the middle of the bottom surface of the mounting plate (100) is provided with a visible light positioner (200), and the bottom surface of the mounting plate (100) is provided with several automatic tracking light communication apparatuses (300) around the visible light positioner (200); the visible light positioner (200) is connected to the plurality of automatic tracking light communication apparatuses (300) by means of a serial bus; the visible light positioner (200) cyclically broadcasts, to a coverage area, the ID of the micro base station and the current working state data of the automatic tracking light communication apparatuses (300); the user receiver (400) sends its own 3D position coordinates and a user identity identifier to the visible light positioner (200); and the visible light positioner (200) designates an automatic tracking light communication apparatus (300), which is the closest to a user and is idle, to establish a communication link with the user receiver (400). The bottleneck problems of the poor radiation communication quality and a high bit error rate of point-to-plane or stereoscopic space of light communication can be effectively solved.
