Multi to one IoT IoT System using Multi-to-one Visible Light Communication

摘要

The present invention relates to an internet of things (IoT) system using multi-to-one visible light communications, capable of collecting and checking various kinds of information through multi-to-one visible light communications in a space in which radio frequency (RF) communications are restricted. According to the present invention, the IoT system using multi-to-one visible light communications, which monitors data collected through a sensor, comprises a sensor data transmission unit (100) converting data measured by a plurality of sensors (111) into encoded visible light communication data to transmit the data, and a sensor data reception unit (200) receiving the encoded visible light communication data transmitted through the sensor data transmission unit (100) in a multi-to-one scheme, decoding and recovering the encoded visible light communication data into raw sensor data, and displaying the recovered sensor data on a screen to monitor the data. Accordingly, provided is a system using the multi-to-one visible light communications to collect and monitor data of various sensors.
