example

[0046] see figure 1 , the road automatic toll collection system includes:

[0047] Equipment 11: Road vehicles. According to the relevant national regulations, vehicles need to follow the relevant regulations to pay the toll when passing the road. Therefore, road vehicles are the subject of charging.

[0048] Device 12: a charging information storage module and a visible light communication sending module. The charging information storage module is used to store charging information, and the visible light communication sending module can take out the information in the information storage module, and control the vehicle headlights to send through proper coding and modulation. When passing the toll booth, the vehicle only needs to turn on the headlights, and the charging information can be sent to the toll booth computer 15 by illuminating the visible light receiver 14 on the lifting pole 13, thereby completing the charging.

[0049] Equipment 13: Toll station lifting pole....

Abstract

The invention provides an automatic road toll system and method based on visible light communication. The system comprises a toll information storage module, a visible light communication sending module, a visible light communication receiving module and a toll processing module, the visible light communication sending module is installed on a vehicle and is connected with a headlight of the vehicle, the visible light communication receiving module is installed in a road toll station, the toll information storage module is used for storing toll information of a user of the vehicle, the visible light communication sending module is used for performing encoding and modulating according to the toll information, generating waveform data suitable for being loaded on visible light and controlling the headlight of the vehicle to send the waveform data in the form of a visible light signal, the visible light communication receiving module is used for receiving the visible light signal sent by the headlight of the vehicle, restoring the visible light signal into digital information, and sending the digital information to the toll processing module, and the toll processing module accomplishes release control and toll recording and processing. The system can completely solve the problems existing in recognition rate, interference immunity and security of ETC adopting microwave wireless transmission.

Description

technical field [0001] The invention relates to an automatic road toll collection system and method based on visible light communication. Background technique [0002] The non-stop charging system (also known as the Electronic Toll Collection System, referred to as the ETC system) uses wireless technology to complete the data communication between the vehicle and the toll station, to perform automatic vehicle identification and the exchange of relevant charging data, and to collect charging data through the computer network. processing to realize a fully electronic toll collection system that automatically collects fees without parking. [0003] Due to the broadcast characteristics of the wireless channel itself, electromagnetic wave propagation lacks good directionality, so the ETC system that has been partially deployed currently generally requires vehicles to slow down when passing, which objectively reduces communication efficiency. What is even more unsatisfactory is t...
