Automobile headlamp based on visible light communication technology

Abstract

The invention discloses an automobile headlamp based on a visible light communication technology, and relates to the field of automobile communication. The automobile headlamp comprises an information sending assembly and an information receiving assembly. The information sending assembly comprises a vehicle-mounted microphone, a signal modulation module, an optical signal transmitting module and a light-emitting element, and the information receiving assembly comprises an optical signal receiving module, a signal demodulation module and a vehicle-mounted loudspeaker. The light-emitting element comprises an automobile lamp and a laser transmitter, and the laser transmitter comprises a rotating disc, a base, a fixing plate, a motor and a beam expanding disc. An optical communication system is installed on an automobile, and the voice information of a driver can be sent to the vehicle-mounted loudspeakers of other drivers with light as a carrier, so that the barrier-free communication is achieved. In order to avoid limitation of irradiation angles of front lamps and rear lamps of the automobile, a rotatable laser generator is additionally arranged on the roof of the automobile, so that the multi-azimuth communication requirement of the automobile is met.

Description

technical field [0001] The invention relates to the field of automobile communication, in particular to an automobile headlight based on visible light communication technology. Background technique [0002] During the driving process of the car, many cars will have some unexpected situations, which are not easy for the driver to detect, such as oil leakage from the fuel tank, dropped cargo, foreign objects mounted, abnormal vehicle conditions, and abnormal road conditions ahead, etc. Make the other party aware that drivers cannot communicate effectively, especially on high-speed roads. If the abnormal condition of the vehicle is not discovered in time, it will be very dangerous. This requires a communication system that allows drivers to communicate without barriers to improve driving safety. Interactivity and security. [0003] Visible light wireless communication uses LED as the carrier. Under the premise of not affecting normal lighting, the information is modulated by t...
