Early warning system and early warning method for abnormal vehicle driving

Abstract

The invention provides an early warning system and an early warning method for abnormal vehicle driving. The early warning system comprises a vehicle-mounted early warning device, an information forwarding device and a server, wherein the vehicle-mounted early warning device transmits first vehicle information outwards according to a preset transmission frequency, and the information forwarding device receives and forwards the first vehicle information to the server; the server receives the first vehicle information, determine a first vehicle position, calculates a driving speed of a first vehicle, determines that the first vehicle drives abnormality according to the speed change of the first vehicle and the adjacent vehicles, and generates early warning information which is forwarded to the vehicle-mounted early warning device at the rear of the first vehicle by means of the information forwarding device; and the vehicle-mounted early warning device alerts the personnel in the vehicleaccording to the indication of the early warning information. In this way, whether the vehicle is in an abnormal state can be monitored in real time through the information interaction among the vehicle-mounted early warning device, the information forwarding device and the server in the early warning system, and the personnel in the vehicle can be timely alarmed, thereby being conductive to improving the timeliness of accident early warning.

Description

technical field [0001] The present application relates to the technical field of safety early warning, in particular to an early warning system and early warning method for abnormal vehicle driving. Background technique [0002] With the rapid development of the automobile manufacturing industry, automobiles have gradually become the preferred means of transportation for people to travel. When people travel by car, traffic accidents are prone to occur on expressways with fast speeds and many vehicles. After the accident, because the vehicles behind the accident did not receive early warning and the speed was too fast, it may cause secondary traffic accidents, cause unnecessary casualties, and increase the difficulty of rescue. [0003] At this stage, monitoring video is used to monitor whether there is a traffic accident on the expressway. When a traffic accident is found, the electronic warning signs installed along the road will be used to give early warning to subsequent ...

AI Technical Summary

Problems solved by technology

In the dead corner of the surveillance and in bad weather with low visibility, the surveillance video cannot accurately locate the location of the accident in time, and thus cannot give an early warning

At the same time, limited by the density and area of ​​the electronic warning signs, the driver may not see the prompts given by the electronic warning signs, resulting in poor timeliness and low accuracy of accident warning.
