The automobile has become an indispensable tool of riding instead of walk in modern life, and the vehicle event data recorder is as the requisite additional equipment of car simultaneously, provides very big help for going on a journey, has reduced the probability that the driver of the automobile is corrupted. On the basis of the Internet of vehicles, if a large amount of mass image data acquired in real time in the driving process of the automobile is recorded by the automobile recorder, the road surface condition of a large number of road sections in the area can be known more timely to a certain extent. But current vehicle event data recorder only has vehicle event data recorder and display effect, simple structure, function singleness do not have the function of road conditions information broadcast, also can't share the road conditions information that this vehicle event data recorder gathered. In addition, for traffic conditions in the area where the vehicle is located, the mode of acquiring related road condition information by an automobile driver mainly comprises an FM radio, wireless broadcasting or vehicle-mounted navigation equipment, and because of limited broadcasting times and range and limitation of inherent information delay, the automobile driver cannot acquire more accurate road condition information and cannot confirm or judge the road condition information through related video information, so that the real requirement of an automobile owner cannot be met.
Along with the continuous development and expansion of vehicle networks, a large number of vehicle recorders on vehicles can share the acquired road condition information through the vehicle networks, however, the data acquired by the vehicle-mounted vehicle recorders is only relied on, and the requirement of knowing traffic road surface information in a large area cannot be met far away. In addition, in the prior art, equipment and a system for integrating and processing massive pavement information data and accurately analyzing pavement conditions on each road section in an area are not available, and the calculation capacity and the storage capacity of the Internet of vehicles based on the conventional physical equipment foundation cannot bear the explosively increased data, so that the development process of the Internet of vehicles is greatly restricted.
