Problems solved by technology

[0003] However, video recognition technology is very dependent on external light. When the sun shines directly on the camera or the external light changes greatly (for example: when the sky becomes brighter in the morning and darker in the afternoon), the reliability of the recognition result is even lower than 30%. Unable to provide reliable assistance to vehicles and drivers
[0004] On the other hand, since the video recognition technology can only recognize objects within the visible range, when the vehicle camera is blocked by the vehicle in front, it cannot obtain any road information (for example: when encountering a traffic jam, the car behind the bus cannot In addition, due to the limited visual range of the on-board camera, when a traffic accident or road accident (such as landslides, flooding, icy roads, etc.) occurs far ahead of the vehicle, the on-board recognition Technology also cannot provide effective assistance to the vehicle

Embodiment 1

[0019] figure 1 Embodiment 1 of the present invention provides a structural diagram of an electronic signboard with wireless transceiver function, which can display and regularly broadcast corresponding road sign information by means of wireless communication.

[0020] The electronic signboard includes an information display module 110 and a wireless transceiver module 120, wherein,

[0021] The information display module 110 is used to display the road sign information corresponding to the electronic signboard;

[0022] The wireless transceiver module 120 is used for regularly broadcasting the road sign information corresponding to the electronic sign board by means of wireless communication.

[0023] Among them, the road sign information can be the road sign under normal conditions, or the sign when there is congestion, traffic accident or road abnormality ahead of the road.

[0024] Wherein, the electronic signboard can be fixed at the corresponding position of the road, ...

Embodiment 2

[0032] image 3 A structural diagram of a road information interaction system provided in Embodiment 2 of the present invention, the road information interaction system includes an electronic signboard 210 and a vehicle 220, and the vehicle 220 includes a wireless receiving module 221, wherein,

[0033] The electronic signboard 210 displays its own road sign information, and regularly broadcasts its own road sign information by means of wireless communication;

[0034] The wireless receiving module 221 receives and processes the road sign information corresponding to the electronic signboard 210 .

[0035] After the electronic signboard 210 receives the road sign information, it displays its own road sign information and sends it to the vehicle 220 regularly by means of wireless communication. The wireless receiving module 221 of the vehicle 220 receives the road sign information corresponding to the electronic signboard 210. processing for the driver's reference.

Abstract

The invention discloses an electronic denoter and a road information interaction system. The electronic denoter comprises an information display module and a wireless transceiver module, wherein the information display module is used for displaying road sign information corresponding to the electronic denoter, and the wireless transceiver module is used for employing a wireless communication mode to broadcast the road sign information corresponding to the electronic denoter at a fixed time. Through the electronic denoter, the road sign information corresponding to the electronic denoter can be efficiently and accurately acquired by vehicles or drivers.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of wireless communication, in particular to an electronic signboard and road information interaction system. Background technique [0002] With the advancement of science and technology, automatic driving technologies such as assisted driving and unmanned driving have gradually entered people's field of vision. To realize automatic driving, it is necessary to realize accurate identification of road conditions. The current common practice is to install video recognition equipment on the vehicle, use cameras and video recognition technology to identify road conditions and road signs, and then automatically adjust the vehicle's driving speed and direction or give the driver necessary tips based on the recognition results. [0003] However, video recognition technology is very dependent on external light. When the sun shines directly on the camera or the external light changes greatly (...
