Variable information board capable of interacting information with unmanned vehicle and implementation method

Abstract

The invention provides a variable information board capable of interacting information with an unmanned vehicle and an implementation method. The system comprises a road information receiver, a signal controller, a visual information display device and an ultraviolet communication device, and a matched ultraviolet information receiver is installed on the unmanned vehicle. The variable information board displays received road information through the visual information display device and broadcasts the received road information through the ultraviolet communication array, an unmanned vehicle can read panel information through the visual sensor and can also receive ultraviolet signals, and enough information can be obtained so that a driving computer can make better judgment. Compared with previous facilities, the variable information board is more intelligent, and due to the fact that the ultraviolet communication array is used, the communication range is wide, and the environment adaptability is high.

Description

technical field [0001] The invention belongs to the technical field of traffic equipment, and in particular relates to a variable intelligence board capable of interacting with unmanned vehicle information and an implementation method. Background technique [0002] With the continuous increase in the mileage of expressways and the number of motor vehicles in our country, the road conditions of expressways are becoming more and more complicated. How to ensure the driving safety of expressways, give timely warnings to drivers, and conduct fast and effective traffic guidance to vehicles to avoid accidents It is one of the key points of expressway management work. At present, the traffic guidance methods of expressways mainly include variable information boards, broadcast signals and mobile phone navigation. [0003] Variable information board, also known as variable information sign, refers to a road traffic sign that is controlled by a remote control device and displays the d...

Problems solved by technology

However, the positioning accuracy of the current GPS is only 3 meters, and there is a certain delay in the current navigation system. Unmanned vehicles cannot use this part of information in time when making decisions.

Although unmanned vehicles can read the information on the variable information board in time through visual sensors, the system will not work properly if it encounters severe weather conditions such as rainy days and foggy days

On the one hand, the above reasons may easily lead to potential safety hazards in the driving of unmanned vehicles; on the other hand, it may also easily lead to a reduction in road traffic efficiency.
