Embodiment 1

[0058] Example 1. Safe driving with in-vehicle auxiliary data transmission based on optical tags. Vehicles A and B are driving on the same road and in the same direction. Vehicle A is in front, vehicle B is behind, and vehicle B is following closely behind. Safe driving data sharing is implemented between the two based on the on-board auxiliary data transmission of optical tags. Car A encodes its current speed, engine speed, accelerator position, and steering wheel steering data into optical tag data, which is displayed on the optical tag of the parking space; Car B scans the optical tag in the front view and finds the Light tag; Car B conducts a consistency check to confirm that the light tag is the light tag of car A; by reading the data of the light tag, car B can grasp the driving parameters of car A, perform emergency braking or steering on car A, and control the driving The system responds promptly and quickly.

Embodiment 2

[0059] Example 2. Navigation information sharing based on optical tag-based in-vehicle auxiliary data transmission. Vehicles A and B are driving on the same road and in the same direction. Vehicle A is in front, vehicle B is behind, and vehicle B is following closely behind. The two vehicles share navigation information based on the on-board auxiliary data transmission based on optical tags. Car A encodes its navigation information data into optical tag data, which is displayed on the optical tag of the parking space; Car B scans the optical tag in the front view and finds the optical tag of Car A; Car B conducts a consistency check to confirm The light tag is the light tag of car A; by reading the data of the light tag, car B understands the navigation information of car A, refers to its own navigation data, and optimizes driving route planning.

Embodiment 3

[0060] Example 3. Social relationship recommendation for in-vehicle auxiliary data transmission based on optical tags. Vehicles A and B are driving on the same road and in the same direction. Vehicle A is in front, vehicle B is behind, and vehicle B is following closely behind. Social relationship recommendation is implemented between the two based on the on-board auxiliary data transmission of optical tags. The members of vehicles A and B find that the two vehicles are on the same road. In order to relieve the loneliness in the driving process, they need to establish social relationships. Car A encodes its social software user ID (WeChat, IG, etc.) into optical tag data, which is displayed on the optical tag of the parking space; Car B scans the optical tag in the front view and finds the optical tag of Car A; Car conducts a consistency check and confirms that the light tag is the light tag of car A; by reading the data of the light tag, car B obtains the social software use...

Abstract

The invention provides a vehicle-mounted auxiliary data transmission method based on an optical label. The optical label and an optical label collecting device are arranged on two driving vehicles which need to transmit data on a road respectively or at the same time. The optical label displays the data information in the form of the optical label. The optical label collecting device on the other vehicle collects the displayed data and inputs the data into a vehicle-mounted computer of the vehicle where the optical label collecting device is located, so as to assist the vehicles to carry out related operations. According to the invention, the information interaction advantage of the optical label is used; the method has the advantages of simple and reasonable process, high passageway directivity of data interaction between vehicles, short action distance, large information transmission capacity and low equipment cost; and an upper layer application based on the technology is rich.

Description

technical field [0001] The invention relates to optical communication technology, in particular to an optical label-based vehicle auxiliary data transmission method. Background technique [0002] During the driving process of the car, some information and data may need to be transmitted between the front and rear cars to assist the driver's driving and improve safety or road utilization. However, there is currently no data transmission method for transferring data between unfamiliar vehicles with precise direction-related orientation, leading to problems in driving data sharing. [0003] Existing communication methods all have their own defects, which cannot solve the above problems, as follows: [0004] communication technology connection authentication Directivity Range Bluetooth must none close WiFi must none nearer cellular communication must none Far infrared no need none close Optical Communication no n...
