Description

Mountain road bend blind area meeting alarm system

Technical Field

The utility model relates to a bend meeting alarm field especially relates to a mountain road bend blind area meeting alarm system.

Background

At the curve of mountain road, the vehicle is easy to be difficult to find the coming and coming of the opposite curve in time because of reasons such as improper speed control and insufficient safe driving sight distance, resulting in the meeting of two vehicles or the meeting of people and vehicles avoiding untimely, and further causing the collision accident. In fact, at the curve of the bidirectional lane of the mountain road, the driver tends to drive at the center of the road for safety reasons, and it is difficult for the driver to judge the position of the curve at night and in heavy fog weather, which further aggravates the occurrence rate of traffic accidents.

In the prior art, only spherical mirrors can be placed on curves with large dead zones of mountain roads, and the problem of vehicle intersection of the curves with the dead zones is solved by the spherical mirrors. However, in order to obtain information prompt by the vehicle meeting prompting method, a driver must drive the vehicle to a position close to the spherical mirror to see the opposite vehicle reflected by the spherical mirror, and cannot obtain prompt in advance to make judgment and response. Meanwhile, in rainy and foggy weather and night driving, the spherical mirror can be blurred under the influence of natural environment, and a driver can hardly recognize the opposite vehicle through a reflected image of the spherical mirror. On the other hand, the spherical mirror is easy to damage and is not easy to place at a narrow bend. A curve crossing early warning system is sequentially used in the Fuling section of the 319 national road of Chongqing city and the Nanchang Meilin scenic spot, and driving data such as the speed of passing vehicles and the like are collected in real time through road surface wireless sensors embedded at the two ends of a curve and are sent to an early warning display screen beside the road. Through the display screen, the driver can know the information of the vehicle running in the opposite lane ahead before entering the curve, so that the driver is effectively reminded to carefully drive through the curve at a reduced speed. It is not enough to lie in burying the sensor underground at ground excavation, easily causes the influence to ground, can not detect the human body, does not have the suggestion of bend, promptly: when no vehicle arrives at the exit of the curve, the entrance of the curve does not display information, and a driver about to enter the curve cannot know the information that the curve exists in front.

Therefore, it is urgently needed to develop a set of curve blind area vehicle meeting prompting system to enhance the reliability and safety of the curve vehicle meeting in the mountain road blind area and reduce the accident rate. If the mountain road curve blind area vehicle crossing prompting system can be applied to mountain roads, the application range of intelligent traffic can be expanded, and the blank of application of intelligent traffic in villages can be filled.
