Description

TECHNICAL FIELD

[0001] The utility model relates to traffic warning device field, especially, it relates to a kind of over road pedestrian detection and early warning complete equipment, can detect the pedestrian of over road, over road in time, and timely to the vehicle that comes to send early warning signal. BACKGROUND

[0002] In various roads in city, countryside, open field etc., there are numerous intersections and openings (hereinafter referred to as "intersections"). In these intersections, especially some signal light controlled sections, or night lighting sections, or areas where the view is blocked due to road curves and inclines, it is difficult for car drivers to timely find pedestrians, animals or obstacles that cross the road, thereby greatly increasing the risk of traffic accidents.

[0003] In addition, even if flashing warning lights are set up at some intersections, due to the lack of intelligent recognition function, the warning mode cannot be adjusted according to the specific situation, and the warning light often flashes for a long time, which cannot effectively prompt the real danger on the road. This long-term and single warning mode is easy to make drivers accustomed to it, which leads to a gradual decrease in attention to warning lights, making it difficult to react quickly when encountering unexpected situations, and thus easily leading to traffic accidents.

[0004] Although the existing pedestrian detection and early warning system can partially solve the above problems, it generally has the following shortcomings:

[0005] 1. Insufficient detection accuracy: Most existing pedestrian detection systems rely on a single sensor for detection, such as a simple camera or infrared sensor, which cannot accurately identify the behavior characteristics of multiple targets (such as pedestrians, animals, obstacles) in complex road environments. This leads to frequent false positives and false negatives, which cannot effectively protect the safety of pedestrians and vehicles.

[0006] 2. Single warning mode: Most current warning devices only provide single sound and light alarms or simple prompts, and cannot adopt diversified warning methods according to different risk levels. This single mode of warning has limited effect, especially in noisy and insufficient light conditions, which makes it difficult to attract the attention of drivers, thereby increasing the probability of traffic accidents.

[0007] 3. Lack of environmental adaptability: Most existing detection devices do not have functions for adverse weather or special environments, for example, in heavy rain, fog or night conditions, the recognition and warning effect of the system is significantly reduced, and it is easily disturbed by the environment, which leads to insufficient stability and reliability of the device in outdoor application.

[0008] 4. Low energy utilization efficiency: Many devices rely on external power supply and fail to consider low-power design, lacking independent power supply modules. In places without external power supply (such as remote roads, temporary construction areas), it is difficult to work normally, which limits the application range of the system.

[0009] 5. Difficult maintenance and installation: Current systems often lack modular design in maintenance, and the repair and replacement process of the equipment is cumbersome, and the adjustment flexibility of the installation angle and position is insufficient, which cannot be easily adjusted according to the road environment. This not only increases the installation and maintenance cost, but also makes the equipment not flexible enough in the changing road environment.

[0010] 6. Lack of self-protection and safety protection measures: Most devices do not integrate lightning protection, dustproof, waterproof and other safety protection measures, and are easily damaged by weather or natural factors during long-term outdoor operation, which seriously affects the service life and safety, leading to frequent replacement and maintenance.

[0011] The above problems show that the existing technology has significant defects in detection accuracy, warning effect, environmental adaptability, installation flexibility and safety, which cannot meet the current growing demand for traffic safety management. Therefore, there is an urgent need for a pedestrian detection and warning complete set of equipment with higher detection accuracy, various warning methods, strong environmental adaptability and easy maintenance and installation to ensure the safety of the traffic environment and efficient operation of the equipment.
