Description

Technical Field

[0001] The present invention belongs to the technical fields of traffic safety technology and intelligent traffic application technology, and particularly relates to a fast real-time display control device for a multi-modal traffic warning information LED display screen. Background Art

[0002] At present, the application of vehicle-road cooperation technology in the traffic field has developed rapidly. According to the real-time state of the road, traffic information and warning information are provided to vehicle drivers through roadside display devices, which is of great value to driving safety and traffic efficiency. At present, the main display device for releasing information from the roadside to drivers is a variable message sign, which is essentially an LED dot matrix display screen. In a general LED display screen, each LED emits light under the control of one or several control boards to form the required graphics and texts, and its function is determined by the control board.

[0003] However, the functions of current LED display screen controllers cannot fully meet the display requirements of traffic system warning information. For example: current LED display screen controllers cannot respond to control instructions in a timely manner (the response usually has a delay of seconds level), and cannot complete functions such as turning off the display, switching the display content, and starting the display. This is not applicable in traffic warning situations where the display content needs to be changed in real time. Especially when releasing traffic warnings and early warning signals, if it cannot respond quickly, the best warning opportunity will be missed, which is not conducive to the release of real-time information. Some traffic warning signs with fixed display content can start and stop displaying in response to control instructions in real time through switches, but the display content is relatively fixed and cannot meet the flexible needs of on-site display content. Therefore, how to overcome the deficiencies of the prior art is an urgent problem to be solved in the current technical fields of traffic safety technology and intelligent traffic application technology. Summary of the Invention
