Short-range wireless communication CCD energy saving control device

Abstract

The invention discloses a short-range wireless communication CCD energy saving control device, comprising: a bridge circuit used for connecting a computer USB interface and an optical transceiver circuit, and receiving or transmitting a signal converted from a computer USB data signal; a central processor, a field-programmable gate array circuit, a power circuit and an optical key circuit, wherein the power circuit is separately connected with the central processor and the field-programmable gate array circuit; and a solar cell panel, a voltage stabilizing circuit, a power supply controller and a DC power supply circuit are provided in the power circuit. The system realizes the point-to-point communication mode, and adopts relatively small receiving and transmitting angles during reception and transmission. Only manual coarse alignment is needed when the system is used, the system can be applied to indoor short-range wireless communication and can reach a data communication rate higher than 10Mbps, the transmission distance is about 5 meters, and thus the data communication requirements of offices, laboratories, homes and other indoor environments are basically satisfied.

Description

technical field [0001] The invention relates to the technical field of visible light communication, in particular to a short-distance wireless communication CCD energy-saving control device. 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. [0004] Visible light co...

Problems solved by technology

[0008] 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.
