Abstract

The present disclosure provides a vehicle-mounted visible light emission system and reception system and a communication network. The vehicle-mounted visible light emission system comprises: a vehicle information acquisition unit configured to acquire vehicle information to be transmitted; a processing unit configured to process the vehicle information acquired by the vehicle information acquisition unit; and a visible light emission unit configured to transmit a visible light signal in a manner of switching between dimming and brightening over time based on the processed vehicle information.

Claims

1. A vehicle-mounted visible light emission system, comprising:

a vehicle information acquisition unit configured to acquire vehicle information to be transmitted;

a processing unit configured to process the vehicle information; and

a visible light emission unit configured to transmit a visible light signal in a manner of switching between dimming and brightening over time based on the processed vehicle information.

2. The system according to claim 1, wherein the vehicle information is image information collected by a camera or vehicle operation information collected from a vehicle electronic system.

3. The system according to claim 1, wherein processing the vehicle information comprises at least one of:

modulation, compression, encryption, and encoding.

4. The system according to claim 1, wherein the processed vehicle information is in a form of binary code stream, and the visible light emission unit is configured to:

enter a “

light emission-enabled”

state for “

1”

in the code stream; and

enter a “

light emission-disabled”

state for “

0”

in the code stream.

5. The system according to claim 1, wherein the processing unit is further configured to transmit the vehicle information or the processed vehicle information to a cloud server together with vehicle identification information through wireless communication.

6. The system according to claim 1, wherein the processing unit is further configured to acquire vehicle information of another vehicle from the cloud server through wireless communication, and

the acquired vehicle information of the other vehicle is used as vehicle information to be transmitted.

7. A vehicle-mounted visible light reception system, comprising:

a visible light reception unit configured to receive, from another vehicle, a visible light signal carrying vehicle information of the other vehicle in a manner of switching between dimming and brightening over time, to obtain the carried vehicle information of the other vehicle;

a processing unit configured to process the obtained vehicle information to obtain original vehicle information of the other vehicle; and

a display unit configured to display the original vehicle information or display a corresponding predetermined image according to the original vehicle information.

8. The system according to claim 7, wherein the vehicle information is image information collected by a vehicle-mounted camera or vehicle operation information collected from a vehicle electronic system, wherein

when the vehicle information is the image information collected by the vehicle-mounted camera, the display unit is configured to display the image information, and

when the vehicle information is the vehicle operation information collected from the vehicle electronic system, the display unit is configured to display a predetermined image corresponding to the vehicle operation information.

9. The system according to claim 7, wherein the processing comprises at least one of:

decoding, demodulation, decompression, and decryption.

10. The system according to claim 7, wherein the visible light reception unit is configured to generate a binary code stream as the decoded vehicle information according to the received visible light signal, wherein

“

1”

is generated in the code stream for a visible light signal indicating that light emission is enabled; and

“

0”

is generated in the code stream for a visible light signal indicating that light emission is disabled.

11. The system according to claim 7, wherein the processing unit is further configured to transmit instructions to a cloud server which comprise identification information and/or location information of a target vehicle through wireless communication, so that the received visible light signal carries vehicle information from the target vehicle.

12. The system according to claim 7, wherein the display unit is a head-up display which covers all or at least a part of a front glass of a vehicle.

13. A communication network comprising multiple visible light emission systems and multiple visible light reception systems respectively deployed on multiple vehicles, wherein a visible light emission system and a visible light reception system are deployed on each vehicle, wherein

each visible light emission system comprises:

a vehicle information acquisition unit configured to acquire vehicle information to be transmitted;

an emission processing unit configured to process the vehicle information; and

a visible light emission unit configured to transmit a visible light signal in a manner of switching between dimming and brightening over time based on the processed vehicle information, and

each visible light reception system comprises;

a visible light reception unit configured to receive, from another vehicle among the multiple vehicles which is different from a vehicle in which the visible light emission system is located, a visible light signal carrying vehicle information of the other vehicle in a manner of switching between dimming and brightening over time, to obtain the carried vehicle information of the other vehicle;

a reception processing unit configured to process the vehicle information of the other vehicle; and

a display unit configured to display the processed vehicle information of the other vehicle or display a corresponding predetermined image according to the processed vehicle information of the other vehicle.

14. The communication network according to claim 13, wherein,

in the vehicle-mounted visible light emission system, processing the vehicle information comprises at least one of modulation, compression, encryption and encoding.

15. The communication network according to claim 13, wherein,

in the vehicle-mounted visible light reception system, processing the obtained vehicle information comprises at least one of decoding, demodulation, decompression and decryption.
