Embodiment Construction

[0009] In view of the increased traffic flow on expressways, especially the high accident rate on specific dangerous road sections, the present invention develops an expressway anti-collision warning system, which is installed on specific road sections to warn vehicles and reduce the accident rate .

[0010] On expressways, limited by specific environmental factors, or some old expressways, limited by design defects of the year, often become accident-prone areas. For example, on some long and gentle road sections, the speed of a large vehicle can be relatively fast when it goes uphill, but when it reaches the top of the slope, its power is insufficient and the speed of the vehicle drops. There are also some special terrain road sections that require the vehicle to slow down, but when the front vehicle decelerates normally, the rear vehicle follows the vehicle too closely, resulting in a lack of response and a rear-end collision. In these road sections, the existing scheme is ...

Abstract

The present invention discloses a highway anti-collision early warning system. The system comprises a monitoring camera, a range measurer and a plurality of warning lights, the warning lights are installed at the roadside of the highway, and the distance between two adjacent warning lights is not larger than 50m. The highway anti-collision early warning system is characterized in that: the monitoring camera and the range measurer are configured to monitor a vehicle driving on the highway, the speed of two adjacent vehicles at the front and the back and the distance between the two vehicles in real time, and when it is discovered that the distance between the front vehicle and the back vehicle is smaller than a safe distance, the flashing position is located behind the front vehicle and the warning light located at front of the back vehicle is configured to perform warning for the back vehicle.

Description

technical field [0001] The invention belongs to the technical field of transportation, and in particular relates to an anti-collision early warning system for expressways. Background technique [0002] At present, for vehicles traveling on expressways, if anti-collision warnings are required, the anti-collision system carried by the vehicle itself is generally used. However, vehicle anti-collision systems have only been popularized in some vehicles in recent years, and most of them are high-end vehicles, and ordinary vehicles rarely install such devices. With the development of society and economy, the popularity of vehicles, especially the safety of highway driving has become an issue that needs more and more attention, especially in some dangerous road sections, due to environmental restrictions and drivers' safety awareness, coupled with traffic flow increase, resulting in frequent accidents. In addition to strengthening safety education for vehicle drivers, it is also ...
