Indoor wireless CCD controlled automatic curtain

Abstract

The invention discloses an indoor wireless CCD controlled automatic curtain. The indoor wireless CCD controlled automatic curtain comprises a bridge circuit which is used for connecting a computer USB interface and an optical transmitting and receiving circuit, and receiving or transmitting signals which are converted from computer USB data signals; a central processing unit; a field programmable gate array circuit; a power supply circuit and an optical key module. The power supply circuit is connected with the central processing unit and the field programmable gate array circuit. A solar cell panel, a voltage stabilizing circuit, a power supply controller and a direct current power supply circuit are arranged in the power supply circuit. According to the system, a point-to-point communication mode is realized; transmitting and receiving are carried out by using relatively small transmitting and receiving angles; only manual rough alignment is needed when the automatic curtain is used. The automatic curtain is applied to indoor short distance wireless communication. A data communication speed of more than 10 Mbps can be realized. The transmission distance reaches about 5 meters. The data communication demands of indoor environments such as offices, laboratories and homes can be satisfied basically.

Description

technical field [0001] The invention relates to the technical field of visible light communication, in particular to an indoor wireless CCD-controlled automatic curtain. 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

[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.
