Problems solved by technology
However, the link of the optical wireless communication system passes through the atmospheric channel, which is greatly affected by the weather. At the same time, the optical wireless communication has the disadvantage of weak penetration and cannot penetrate non-transparent objects, so it is not as widely used as microwave communication.

The invention discloses a road optical wireless communication method. First, an area is defined on the road, and then an optical wireless communication road surface unit is installed in the area. At the same time, an optical wireless communication vehicle-mounted unit is installed at a suitable position of the vehicle. In the area, information exchange occurs between the optical wireless communication road surface unit and the optical wireless communication vehicle-mounted unit. The invention adopts the optical wireless communication technology, which can transmit a large amount of information within the time when the vehicle passes through a specific area, and can maintain a high transmission rate while having high anti-interference ability. The vehicles of the communication road surface unit can carry out real-time information collection.
Description
technical field [0001] The invention belongs to the technical field of optical communication, in particular to a short-distance wireless optical communication transmission method. Background technique [0002] As a new type of wireless communication technology, optical wireless communication can realize broadband transmission without spectrum use license, and is resistant to electromagnetic interference and has good confidentiality. The light source for optical wireless communication also has the advantages of low power consumption, long life, and low price. [0003] In the optical wireless communication system, LED is used as the light source at the transmitting end, and a photodetector (PD) is used at the receiving end for receiving. However, the link of the optical wireless communication system passes through the atmospheric channel, which is greatly affected by the weather. At the same time, the optical wireless communication has the disadvantage of weak penetration and...
