detailed description

As shown in Figure 1, the road signal warning system for sharp curves of the present invention includes a curve signal light and a video vehicle detector; there are two said curve signal lights, which are respectively arranged on the roadsides of the traffic lanes in two directions of the curve, and The curve signal lamp faces the direction of the coming vehicle; there are two voice prompt horns, which are respectively arranged on the rods of the curve signal lamp; On the driving lane, the video vehicle detector includes a camera, data transmission equipment, supplementary lights and a video processor; the camera collects vehicle driving information on the driving lane, and the data transmission device transmits the information collected by the camera to the video processor; the video processor processes the information and Control the signals and horns of the curve signal lights on both sides. The supplementary light is used to cooperate with the camera to take pictures and shoot. The curve signal lights are equipped with a delay module; After the time delay expires, the curve lights go out.

Further, the video vehicle detector is 30-80m away from the curve signal light on the same side; the curve signal light is closer to the center of the curve than the video vehicle detector. In the embodiment shown in FIG. 1 of the present invention, the video vehicle detector is 50m away from the curve signal lights on the same side.

As shown in Figure 2, the early warning method of the sharp road signal light early warning system:

When no vehicle enters the curve, the curve signal light is always green;

The video vehicle detector detects lane information; when the car enters a curve, the video vehicle detector on the lane in this direction detects the vehicle and automatically measures the speed of the vehicle. On the one hand, the video processor of the video vehicle detector controls the curve of the opposite lane. The green light of the road signal light turns off, the yellow light turns on and the voice prompts "the car ahead", on the other hand, it is judged whether the vehicle on this side is speeding; if the vehicle speeds up, the green light of the curve signal light of the lane in this direction turns off and the yellow light turns on, and the voice prompts "you are speeding" , to remind the driver to pay attention;

When the yellow light of the curve signal light is on, the delay program will be activated, and the yellow light will turn off and return to the green light after the delay is over.

The curve signal lamp has two display modes of yellow and green. It is completely the same as the color display and color meaning of the existing traffic information lights; green represents passability, and yellow reminds drivers to pay attention. The present invention does not use the signals of signal lamps to distinguish whether the vehicle in this direction is speeding or there is a vehicle in the opposite lane. When either of the two occurs, the yellow light is used to prompt, so as to avoid introducing the display mode or color of other signal lamps, causing the driver to misjudge.

And in order to further distinguish when the yellow light is on, whether the vehicle on this side is speeding or there is an oncoming vehicle in the opposite lane, the described sharp bend road signal warning system is also provided with a voice prompt device, and the voice prompt device is connected with the video processor, and the voice prompt device can Play the pre-stored voice prompts to distinguish whether the vehicle on this side is speeding or there is an oncoming vehicle in the opposite lane.

Curve signal lights and horns are generally cantilevered on the roadside of the curved roadway to remind drivers and pedestrians to watch out and pass the curve after confirming safety. Sharp turn traffic warning signal lights should be set according to the shape of the curve, so visually, the direction of the signal light is on the side of the curve driving, and the signal light should be set near the center point of the curve, the purpose is to make the traffic at both ends of the curve The driver is able to see the warning lights separately.

Cantilever-type installation is adopted, and the height is 5.5m to 7m; when column-type installation is adopted, the height should not be lower than 3m; when installed on the overpass body, the height should not be lower than the clearance of the bridge body.

The video vehicle detector only needs to install cameras and data transmission equipment in the field. Generally, a T-shaped bar is installed on the inner side of the curve, and a camera and a supplementary light are installed on the beam to take images of a section in one direction. Data transmission equipment and power supply equipment are installed in the cabinet on the column. The video processor is arranged in the chassis, and the detected traffic flow information is transmitted to the processor, and then the processed information is transmitted to the curve signal lights.

Traffic signal light technology has a very mature variety of products, the curve signal light warning system can choose 300-type double-lens motor vehicle full-screen lights; working voltage: AC85V-265V 60HZ/50HZ; material: PC or die-cast aluminum, in line with the requirements of the Chinese people The Republic of GB14887-2011 standard, CE certified products. When the video vehicle detector detects the incoming vehicle information, the yellow light of the opposite signal light is on, and the delay program is enabled, such as setting the delay time to 10s; when there is no incoming vehicle in the opposite direction, the green light of the opposite signal light is on.
