Abstract

The invention discloses a visible light communication power supply system, comprising: an AC-DC module and a DC-DC module; the AC-DC module is connected to a 220V AC voltage, and includes 5 power supply outputs, respectively +33V, +27V, +12V , +8V, ‑8V; DC‑DC module includes 10 outputs, respectively +30V, +23V, +5V, ‑5V, +2.5V, auxiliary +2.5V (AUX), +1.8V, +1.2V, +1V, 300mA constant current source. Among them, +1.2V is used to supply power to the core of the signal processing module first, and +1V is used to supply power to the peripheral circuits of the signal processing module after the kernel starts normally, and then the auxiliary +2.5V is used to supply the input / output of each bank of the signal processing module power supply.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a power supply system for visible light communication. Background technique [0002] Visible light communication technology uses high-speed bright and dark flickering signals invisible to the naked eye emitted by fluorescent lamps or light-emitting diodes to transmit information. Connect the high-speed Internet wire device to the lighting device and plug it into the power plug to use it. The system made by using this technology can cover the range reached by indoor lighting, and the computer does not need to be connected by wires, so it has broad development prospects. [0003] The traditional visible light communication power supply system generally uses a regulated power supply for power supply. Generally, only the transmitter (including the signal processing module) side needs 5 different voltages, and the receiver (including the signal processing module) needs 6...
