Vehicle information transmission system based on Li-Fi technology

Abstract

The invention provides a vehicle information transmission system based on the Li-Fi technology, and relates to the technical field of wireless communication. The vehicle information transmission system provided by the invention comprises multiple groups of Li-Fi modules, a central processing module and Li-Fi base stations. The multiple groups of Li-Fi modules are used for establishing a wireless communication network between vehicles and transmitting travelling information of the vehicles in a two-way manner, and each group of Li-Fi modules comprises a Li-Fi transmitting unit and a Li-Fi receiving unit. The central processing module is electrically connected with each Li-Fi module through a CAN bus and is used for outputting a control signal to control the working state of each Li-Fi module and displaying the travelling information in real time. The Li-Fi base stations are arranged at the positions of street lamps on two sides of a road, and the Li-Fi base stations are connected to theInternet of Vehicles through communication optical fibers. At least one group of Li-Fi modules is arranged in the front of the vehicle, and at least one group of Li-Fi modules is arranged at the rearof the vehicle. The vehicle information transmission system provided by the invention is high in information transmission speed and low in use cost, and no additional hardware device needs to be added.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a vehicle information transmission system based on Li-Fi technology. Background technique [0002] With the improvement of people's living standards, the number of automobiles in our country is constantly increasing, followed by the increase of automobile safety accidents in our country, causing a large number of casualties. At present, many major traffic safety accidents are mainly the serial final accidents concentrated on expressways. When the initial rear-end collision occurs, the vehicle behind may be able to detect the unexpected situation in time and take emergency braking, but the owner of the vehicle behind cannot detect the rear-end collision in time due to the occlusion of the vehicle in front and the vehicle speed is relatively fast. Very likely to cause major serial rear-end collision accidents. At present, car owners mainly obtain road condition inf...

Problems solved by technology

When the initial rear-end collision occurs, the vehicle behind may be able to detect the unexpected situation in time and take emergency braking, but the owner of the vehicle behind cannot detect the rear-end collision in time due to the occlusion of the vehicle in front and the vehicle speed is relatively fast. Very likely to cause major serial rear-end collision accidents

At present, car owners mainly obtain road condition information ahead through traffic broadcasting, and there is a serious information lag
