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 structure. 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 u...

Abstract

The invention provides a network connection method based on visible light communication. The method comprises the following steps: arranging an LED lamp for visible light communication indoors; arranging the wireless communication equipment in a coverage area of the visible light communication network and enabling the wireless communication equipment to be connected with the visible light communication network, so that the wireless communication equipment is connected with a plurality of network connection lines; and selecting the network connection line with the shortest optical path from the plurality of network connection lines as a communication line, and shielding other network connection lines. The wireless communication equipment selects one network connection line with the shortest optical path for communication and shields other network connection lines, so that the wireless communication equipment can only receive one network connection line, and errors such as messy codes caused by receiving a plurality of network connection lines are avoided; and meanwhile, a connected line cannot be reflected on objects such as a wall surface, so that not only is the transmission speed ensured, but also the signal strength and accuracy are ensured. The problem of signal distortion or error caused by a multipath effect of existing visible light communication is solved.

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...
