Embodiment Construction

[0048] The network connection method based on visible light communication proposed by the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention. In addition, the structures shown in the drawings are often a part of the actual structures. In particular, each drawing needs to display different emphases, and sometimes uses different scales.

[0049]It should be noted that "first", "second", etc. in the specification, claims and description of the drawings of the present invention are used to distinguish similar objects in order to describe the embodiments of the present invention, and are not used to describe specific It is to be understood that the constructions so used are interchangeable ...

Abstract

The present invention provides a network connection method based on visible light communication, including: LED lights for visible light communication indoors; placing wireless communication equipment in the coverage area of visible optical communication network and connecting to visible light communication networks to make wireless communicationThere are multiple network connection lines in the device connection; select the shortest optical line from multiple network connection lines as communication lines, and block other network connection lines.By selecting a wireless communication device to select a network connection line with the shortest optical range for communication and blocking other network connection lines, the wireless communication equipment can only receive one network connection line, so as to avoid errors caused by multiple network connection lines and other errors.At the same time, the connected lines will not reflect on objects such as wall surfaces, which not only ensure the transmission speed, but also ensure the strength and accuracy of the signal.Solved the problem of signal distortion or error caused by the existing visible light communication due to multi -diameter effects.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a network connection method based on visible light communication. Background technique [0002] With the development of wireless communication technology, the electromagnetic frequency band used for wireless communication has gradually been unable to meet people's communication needs. Therefore, people have changed from wireless communication technology using electromagnetic waves as a carrier to wireless communication technology using light waves as a carrier. Among them, the most popular one is visible light communication. [0003] Visible Light Communication (VLC) is a new wireless transmission technology that uses the visible light spectrum for data transmission. By implanting a tiny chip on the LED, it uses electrical signals to control the LED to send out high-speed flashing signals invisible to the naked eye. To transmit information, for example, LE...
