Road warning device

Abstract

The invention provides a road warning device. The device is arranged on an intersection of roads. The intersection is provided with a plurality of sensing areas and a plurality of warning areas; a vehicle driving on a road reaches one sensing area, one sensing area on another road which intersects with the driving direction of the vehicle gives a meeting warning; the road warning device comprisesa plurality of vehicle detector modules arranged in the plurality of sensing areas and a plurality of warning lamp modules arranged in the plurality of warning areas; each vehicle detector module is provided with at least one sensing device for detecting passing of vehicles; the vehicle detector module transmits a trigger signal to the corresponding warning lamp module by using a wireless transmitting-receiving module, wherein the warning lamp module is in the warning area of the road intersecting with the driving direction of the vehicle; the warning lamp module receives the trigger signal; the trigger signal drives a light-emitting piece to act so as to generate warning light, so that pedestrians are reminded that vehicles are about to meet at the intersection, and the purpose of preventing traffic accidents is achieved.

Description

technical field [0001] The present invention relates to a road warning device, especially one that is installed at a road crossing, where a plurality of sensing areas and a plurality of warning areas are respectively arranged at the intersection, and a vehicle traveling on the road reaches the sensing area Afterwards, a traffic warning will be made for a while in the warning area of ​​another crossing road in the direction of travel of the vehicle, so as to prevent traffic accidents from happening. Background technique [0002] Traffic safety is an item that every government wants to improve, especially for crossroads or multi-intersections that only use traffic lights to control traffic. It is still impossible to prevent traffic accidents, so in addition to traffic lights, some assistance is still needed Traffic equipment to reduce the incidence of accidents. The existing auxiliary traffic equipment on roads without traffic lights is to install wide-angle convex reflectors ...

AI Technical Summary

Problems solved by technology

[0003] However, the wide-angle reflectors currently installed at intersections are often affected by dust or water splashes when vehicles pass by. The mirror surface is often dirty and it is difficult to recognize the reflected image, which greatly reduces the effectiveness of the wide-angle reflector. In addition, pedestrians or drivers People usually have to be close to the wide-angle mirror to see the image reflected by the mirror, and because they have to watch it at a close distance, the fronts of the two cars are already very close when they meet. If one or both of them is too fast, it is easy to A car accident occurs due to the owner's unresponsiveness

Furthermore, the wide-angle reflector also has the problem of the viewer's line of sight angle, that is, when the viewing angle may be skewed, the driver will grasp the distance between the vehicle or the distance between the vehicle and the vehicle by mistake, and it is impossible to prevent accidents. Therefore, the existing auxiliary traffic equipment There are still many shortcomings, which need to be improved by those engaged in this industry
