Hybrid Visible Light Communication (VLC) indoor wireless system for Location Based Services (LBS)

Abstract:

A visible light smart home LiFi remote control system, comprising the following an information acquisition module for obtaining personnel information to output control signals with preset instructions. A LiFi transmitter, coupled with the information acquisition module, receives the transmission signal of the control signal with the output as the optical signal. A LiFi receiver, coupled with the LiFi transmitter, receives transmission signal compilation output control signal. A controller, coupled with the LiFi receiver, receives control signal to output power-on signal. A power switch module, coupled with the controller, responds to the power-on signal to deliver the mains to household appliances. A voltage current sensor, coupled with the power switch module, obtains the current or voltage condition of the mains supply to household appliances to output the current carrier signal. An insurance circuit, connected in series between the voltage current sensor and the power switch module, responds to a carrier signal greater than a set reference signal to output a power-off signal to the power switch module.
