Road safety early warning system and road safety early warning method

Abstract

The invention provides a road safety early warning system and a road safety early warning method. The road safety early warning system comprises a cloud server and an early warning device disposed in a vehicle. The early warning device is used to receive video information shot by a first shooting device, and is used to acquire a detection signal transmitted by a safety sensor. The early warning device is used to determine whether an abnormal condition occurs on a road, on which drives the vehicle, is determined, and is used to transmit early warning information to other early warning devices in the predetermined range of the position of the vehicle. The early warning device is used to transmit a signal used for warning the occurrence of the abnormal condition, the position information of the vehicle, and the video information related to the position of the abnormal condition in a corresponding time period to the cloud server, and the cloud server is used to transmit the early warning information to other early warning devices in the predetermined range of the position of the vehicle, when the abnormal condition of the road occurs. The road safety early warning method is a method adopting the above mentioned system to realize the road safety early warning. The early warning information is transmitted to the surrounding vehicles timely, when safety accidents occur on the road, and therefore a probability of secondary accident occurrence is reduced.

Description

technical field [0001] The invention relates to the field of road safety, in particular to a road safety early warning system applied in the field of vehicle safety and a road safety early warning method realized by the system. Background technique [0002] With the gradual improvement of people's living standards, vehicles have become the most important means of transportation in people's lives, and more and more people buy vehicles. However, the frequency of traffic accidents is also increasing, especially vehicle rear-end collisions occupy a considerable proportion, and often cause heavy casualties and economic losses. [0003] The reason for most rear-end collision accidents is that after the accident or failure of the vehicle in front, the vehicle behind cannot give a warning quickly, which leads to more and larger traffic accidents caused by the rear-end vehicle directly, or because the warning equipment of the accident vehicle has poor visibility. The accident points...

Problems solved by technology

[0013] However, the existing Internet of Vehicles systems usually deal with traffic accidents after the event, that is, after a traffic accident occurs, the cause of the traffic accident is judged by analyzing the driving data of the vehicle. This processing method cannot provide early warning. Traffic accidents cannot be avoided

Since the current Internet of Vehicles system does not send early warning information to surrounding vehicles in time when a traffic accident occurs, subsequent vehicles cannot obtain the situation of traffic accidents ahead in time, and secondary accidents are prone to occur
