Household LIFI photon communication energy-saving system

Abstract

The invention discloses a household LIFI photon communication energy-saving system, which comprises a bridge circuit for connecting a computer USB interface and an optical transmitter-receiver circuit and receiving or emitting signals obtained after conversion processing of computer USB data signals, a central processor, a field-programmable gate array circuit and a power circuit. The power circuit is connected with the central processor and the field-programmable gate array circuit; and the power circuit is internally provided with a solar cell panel, a voltage stabilizing circuit, a power supply controller and a DC power supply circuit. The system realizes a point-to-point communication mode; transmitting and receiving adopt relatively-small reception and emission angles respectively; only manual coarse alignment is needed when the system is used; and the system is used for indoor short-distance wireless communication, can reach data communication rate of 10 Mbps and above and transmission distance of about 5 m, and basically meets data communication requirements of indoor environments of an office, a laboratory and home and the like.

Description

technical field [0001] The invention relates to the technical field of visible light communication, in particular to a household LIFI photonic communication energy-saving system. Background technique [0002] Solar energy is generated by the hydrogen-helium fusion of hydrogen atoms inside the sun and releases huge nuclear energy, which is the radiant energy from the sun. [0003] Most of the energy required by human beings comes directly or indirectly from the sun. Plants release oxygen and absorb carbon dioxide through photosynthesis, and convert solar energy into chemical energy and store it in plants. Fossil fuels such as coal, oil, and natural gas are also primary energy sources that evolved from ancient animals and plants buried underground over a long geological period. The energy contained in the earth itself usually refers to the energy related to the heat energy inside the earth and the energy related to the nuclear reaction.

Problems solved by technology

[0009] Although optical communication has many advantages, there are also some disadvantages, such as: light waves cannot penetrate obstacles such as walls, and are susceptible to interference from background light noise such as sunlight, incandescent lamps, and fluorescent lamps.
