Video based curve early warning system and early warning method

Abstract

The invention discloses a video based curve early warning system and an early warning method. The video based curve early warning system comprises a video acquisition module, a controller, a communication module and an information display module, and is characterized in that the controller is used for processing video images acquired by the video acquisition module; the controller keeps communication with the information display module through the communication module; the video acquisition module comprises a camera and an acquisition card, and the camera transmits video to the controller through the acquisition card; the controller is an industrial control computer; the communication module is a wireless communication module, and the wireless communication module is a DSRC wireless communication module; and the information display module is an information board and / or a voice prompt device. The invention can realize a curve early warning system which is convenient to install, free of damages for the road surface, simple in facility, easy to maintain, stable in system and capable of performing early warning normally at the night of rainy days.

Description

technical field [0001] The invention belongs to the field of safety monitoring and early warning, and relates to a curve early warning system, in particular to a video-based curve early warning system and an early warning method. Background technique [0002] Mountainous roads have large longitudinal slopes and many curves, and they are often continuous sharp curves, which are typical accident-prone road sections. Some necessary safety facilities are usually set up on sharp bends of highways in mountainous areas: [0003] At present, the more common curve warning devices include: such as roadside guardrails, reflective guide signs, sharp curve warning signs, convex reflectors, road pavement with anti-skid materials and deceleration vibration markings, etc. These facilities are more complicated to install and may be damaged. Damage to the road surface, maintenance is also more difficult and the early warning effect is not very ideal. Warning facilities such as reflective gu...

AI Technical Summary

Problems solved by technology

[0003] At present, the more common curve warning devices include: such as roadside guardrails, reflective guide signs, sharp curve warning signs, convex reflectors, road pavement with anti-skid materials and deceleration vibration markings, etc. These facilities are more complicated to install and may be damaged. Damage to the road surface, maintenance is also more difficult and the early warning effect is not very ideal

Warning facilities such as reflective guide signs and sharp bend warning signs cannot play a good early warning role. The convex reflector will affect normal use in rain, fog, snow and night conditions, or if it has not been cleaned for a long time, and the early warning effect will be greatly reduced. And there are many difficulties in installation and maintenance
