[0002] With the continuous development of road network laying work in China, the complexity of the road is increasing, accompanied by the rapid growth of the number of motor vehicles, the problem of traffic safety is increasingly prominent, and it is necessary to set up a warning device in the road section where traffic accidents occur frequently. The traffic safety situation is severe in the mountainous road section as a high-risk road section, especially in the mountainous curved road section, different risk road section warning devices are often used, such as curve reflectors, LED display screens, etc. With the development of intelligent digital traffic, the combination of intelligent digital technology and risk road section warning device can effectively enhance the warning speed and accuracy of risk road section warning.

[0003] At present, the mountainous curved road is relatively narrow, when driving into the mountainous curved road, the driver's view is blocked by the mountain and vegetation, and the information of the oncoming vehicle in the curved road cannot be accurately and timely obtained, so there is a certain risk when meeting at this time. Therefore, a reflector is often set up in the mountainous curved road to help the driver observe the information of the oncoming vehicle in the curved road, so as to avoid meeting in the curved road. The reflector is generally set on both sides of the road at the entrance of the curved road, and the mirror surface of the reflector is tangent to the curved road. The driver can observe whether there is an oncoming vehicle through the reflector when entering the mountainous curved road, so as to avoid meeting in the curved road.

[0004] However, when the curvature of the mountainous curved road is large, the driver's view is blocked by the front mountain when turning, and the driver cannot completely obtain the information of the oncoming vehicle in the mountainous curved road with large curvature through the reflector. When the information of the oncoming vehicle cannot be obtained, there is a certain risk when meeting, but the information obtained by stopping to observe is lagging behind, and there is a risk when observing the oncoming vehicle, at the same time, the mirror surface of the reflector is covered with rain, snow and dust due to the influence of the environment in the mountainous area with fog, rain and dust, at this time, the picture in the reflector is distorted and blurred, and the driver cannot obtain accurate information of the vehicle in the curved road.

[0005] In the prior art, a display screen and a whistle are used to warn the oncoming vehicle in the curved road after the vehicle drives into the curved road and passes over the deceleration zone, however, the oncoming vehicle in the curved road cannot be warned until the vehicle drives into the curved road and passes over the deceleration zone, at this time, it is difficult for the oncoming vehicle in the curved road to avoid the information received, which leads to accidents, at the same time, the display screen is affected by rain and snow in rainy and snowy weather, and the whistle is also difficult to clearly convey to the driver, so the driver cannot accurately obtain the information of the oncoming vehicle in the curved road.
