Abstract

The invention provides a method for transmitting visible light communication data. The method for transmitting the visible light communication data comprises the steps that a data packet in a network is obtained, wherein data in the data packet are parallel data; the data packet is cached to a preset storage position, the data packet is obtained from the storage position and is divided into at least one sub data packet, the data are converted into serial data, line coding is conducted on each sub data packet according to preset line codes, and each sub data packet is transmitted to a controller of an LED lamp so that the controller can control a lamp tube of the LED lamp to be turned on or turned off according to the serial data. According to the method for transmitting the visible light communication data, the data packet obtained in the network is divided into the sub data packets, so that the volume of data contained in each sub data base is small, and the method is suitable for channel transmission for visible light communication of a single line; the data in each sub data packet are made to be adapted to the low-pass characteristic of a channel for visible light communication through line coding, and the transmission accuracy is improved. By the adoption of the method for transmitting the visible light communication data, data information in the network can be obtained in real time, and data information in the network is transmitted in real time according to the visible light communication technology.

Description

technical field [0001] The present invention relates to the field of visible light communication, and more specifically, to a method and device for transmitting visible light communication data. Background technique [0002] With the development of science and technology, wireless communication technologies have been very developed, such as Bluetooth (Bluetooth), Wi-Fi (Wireless Fidelity), WiMax (Worldwide Interoperability for Microwave Access, global microwave interconnection access) and LTE (Long Term Evolution, Long Term Evolution), etc., electronic devices can use the above-mentioned various wireless communication methods to transmit data information in the network. [0003] However, the above-mentioned several wireless communication methods are based on radio communication, and due to the diffraction characteristics of radio signals, they can penetrate some obstacles. Take Wi-Fi as an example. Wi-Fi relies on invisible radio wave transmission. As the power of devices i...
