Abstract

The invention discloses a method for switching visible light wireless communication reception of moving vehicles. The method comprises the steps that when a signal overlapping coverage area exists between adjacent sending ends, a message source with strong signal switching power is selected to be communicated with the signal overlapping coverage area; when a signal overlapping coverage area does not exist between the adjacent sending ends, the uncovered distance between the adjacent sending ends is calculated; time for entering the next sending end coverage range is calculated; through calculation of the data size in the time period, a buffering space of the data size is reserved in a terminal, and therefore network disconnection is not instantly displayed during the time period. The method is applied to communication switching of the vehicles and road lamps, and communication between the vehicles and the road lamps is successfully guaranteed.

Description

technical field

[0001] The present invention relates to the communication field, in particular to a method and device for receiving and switching visible light wireless communication of a mobile vehicle. Background technique

[0002] Visible Light Communication (VLC) is an emerging optical wireless communication technology developed on the basis of white light LED technology. Compared with traditional radio frequency communication and other optical wireless communications, visible light communication has the advantages of no electromagnetic interference, energy saving, integrated lighting and communication functions, green and harmless to human body, etc. It can be seen that VLC technology has great development prospects.

[0003] Outdoor VLC is suitable for wireless short-distance communication in Intelligent Transportation Systems (ITS, Intelligent Transportation Systems). Currently, the wireless short-distance communication technologies used in ITS include WIFI and radio...
