Expressway collision avoidance early warning system and method thereof

Abstract

The invention discloses an expressway collision avoidance early warning system and a method thereof. A guardrail alarm device, a high rod alarm device and a remote controller are included. The high rod alarm device is used to receive an alarm signal when the guardrail alarm device senses that external pressure changes. The high rod alarm device is connected to the remote controller and is used to send position information of the high rod alarm device and an alarm signal in the guardrail alarm device to the remote controller after receiving the alarm signal. The high rod alarm device is also used to carry out early warning signal broadcasting in a coverage area so as to receive a feedback signal of the remote controller. The guardrail alarm device is used to carry out early warning on a position near a guardrail. By using the collision avoidance early warning system, when there is a traffic accident on the expressway, the alarm can be timely triggered and early warning prompt is performed on a rear area so as to avoid crash again. By using the collision avoidance early warning method, after the traffic accident is generated, the early warning prompt can be performed through a plurality of forms.

Description

technical field [0001] The invention relates to the field of automobile active safety early warning, in particular to an expressway anti-collision early warning system and method. Background technique [0002] After a vehicle has an accident on the expressway, often due to factors such as darkness, rain and fog, the vehicle behind cannot know and see in time, resulting in continuous rear-end collisions, so that a single traffic accident has evolved into a large series of traffic accidents. Bring more serious personal and property losses to the society. [0003] In the prior art, mostly only by transforming the vehicle and installing an early warning device on the own vehicle, but the early warning to the rear vehicle cannot be realized, and the traffic accident cannot be prevented from happening again. Contents of the invention [0004] The technical problem to be solved by the present invention is that when a traffic accident occurs on an expressway, an alarm can be trig...

[0002] After a vehicle has an accident on the expressway, often due to factors such as darkness, rain and fog, the vehicle behind cannot know and see in time, resulting in continuous rear-end collisions, so that a single traffic accident has evolved into a large series of traffic accidents. Bring more serious personal and property losses to the society

[0003] In the prior art, most of the vehicles are only modified and equipped with early warning equipment for their own vehicles, but the early warning of the vehicles behind cannot be realized, and the recurrence of traffic accidents cannot be prevented.
