The specific working process is as follows:
when the system works, the traffic state of a road is shot by the fixed traffic monitoring cameras arranged at all positions of the road, and then the video shot by the traffic monitoring cameras is analyzed by the analysis module, so that the visibility information and the meteorological state on the road can be obtained, and early warning is timely carried out on vehicles on the road; because the installation positions of the traffic monitoring cameras are fixed, on the same road, the area between two adjacent traffic monitoring cameras cannot monitor the passing state of the road and the meteorological state on the road, the vehicle passing process is shot through a vehicle traveling data recorder installed on a vehicle, then the video shot by the vehicle traveling data recorder is analyzed by an analysis module, the passing state of the road between the two adjacent traffic monitoring cameras on the road and the meteorological state on the road can be obtained, so that the analysis module can timely send the visibility and the meteorological state at different positions on the road to the vehicle-mounted end of the vehicle traveling on the road, and a driver is reminded and warned; the method comprises the steps that the video uploaded by a driving recorder is analyzed to obtain the actual driving speed of a vehicle on a road, after the actual driving speed of the vehicle exceeds the speed limit standard of the road, an analysis module sends a warning signal to a vehicle-mounted end to enable a driver to slow down and walk, and meanwhile overspeed information is synchronized to a traffic police department to enable the driver to be punished; analyzing vehicle position information uploaded by a driving recorder through an analysis module to obtain an actual vehicle distance between vehicles on a road, then calculating according to the actual vehicle distance, the actual driving speed of the vehicles, visibility data and a driver reaction speed value under a conventional condition to obtain a safe vehicle distance which needs to be met and does not collide between the vehicles when the vehicles are emergently braked, then comparing the actual vehicle distance with the safe vehicle distance through the analysis module, sending a deceleration prompt to a vehicle behind in the driving direction by the analysis module for the vehicle which does not meet the safe vehicle distance, and increasing the actual vehicle distance between the vehicles through the deceleration of the vehicle behind until the actual vehicle distance is larger than or equal to the safe vehicle distance; analyzing videos shot by a vehicle event data recorder to obtain the actual driving speeds of other vehicles driving on the road, then comparing the actual driving speeds of the other vehicles with the speed limit standard of the road, and sending the license plate number of the overspeed vehicle to a traffic police department when the other vehicles are found to be overspeed; when the vehicle is overspeed or other illegal behaviors, the analysis module sends the illegal behaviors of the vehicle to the associated emergency contact position, and meanwhile, when the visibility of the road is low and the fog appears, the analysis module can directly send the reminding information to the mobile phone of the vehicle owner.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
