Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of road traffic safety, and specifically relates to an early warning device for vehicles traveling on curved roads. Background Art
[0002] At present, most of the highway bends do not have advanced oncoming vehicle warning equipment, and a few intersections only have a convex wide-angle mirror as a warning device. Drivers use the convex wide-angle mirror to reflect the approaching vehicle on the bend. Some experienced drivers also use horns to inform their own position to achieve the purpose of warning.
[0003] At the same time, drivers habitually occupy another lane when turning, driving in the middle of two lanes, which is a dangerous driving behavior. In addition, convex wide-angle mirrors cannot play a good warning role in cloudy and hazy weather, resulting in frequent accidents at bends. Utility Model Content

[0006] In some of the embodiments, eight microwave radar sensors are arranged at each curve, distributed in two directions of the road along the center line of the curve, and a spacing of 50-100 is set between the straight road and the starting point of entering the curve. A microwave radar sensor is respectively arranged at the starting ends and the middle within the spacing, and a microwave radar sensor is arranged at the center line of the curve of the road. The sensing detection ends of the four microwave radar sensors on the same side of the curve are all arranged toward the straight road direction of that side of the road.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] See also Figure 1-3 The utility model provides a technical solution: a warning device for vehicles traveling on a curve, comprising a controller, a plurality of microwave radar sensors 1 arranged at a road curve, a plurality of pre-warning lights 2 arranged on both sides of the road curve, and an energy storage power supply for supplying energy to the microwave radar and the pre-warning lights 2. The microwave radar sensors 1 are arranged and installed at a preset distance in the direction of the straight road with the center line 3 of the curve of the road as a reference, the pre-warning lights 2 are arranged at the edge of the road, all the microwave radar sensors 1 and the pre-warning lights 2 are connected to the controller, and the energy storage power supply is a solar energy storage power supply device, which supplies power to the microwave radar, the pre-warning lights 2 and the controller.
[0017] To facilitate the installation of the microwave radar sensor 1, a steel pipe gantry is generally used. The steel pipe gantry is installed on the road, and then the microwave radar sensor 1 is installed above the gantry, so that the microwave radar sensor 1 faces the road direction for vehicle detection.
[0018] The microwave radar sensor 1 performs real-time detection on vehicles expected to enter the curve and vehicles inside the curve, and transmits the detection results to the controller, which controls the pre-warning light 2 on the other side of the curve to display lights, reminding the vehicles on the other side to drive safely.
[0019] Based on the above technical solution, the following installation method is adopted in the specific implementation:
[0020] There are 8 microwave radar sensors 1 arranged at each curve, distributed in two directions of the road with the center line 3 of the curve, and a spacing of 50-100 is set between the straight road and the starting point of entering the curve, and a microwave radar sensor 1 is respectively arranged at the starting ends and the middle of the spacing, and a microwave radar sensor 1 is arranged at the center line 3 of the road curve, and the sensing detection ends of the 4 microwave radar sensors 1 located on the same side of the curve are all arranged toward the straight road direction of the road on that side.
[0021] On a road with a spacing of 50-100 between a straight road and a starting point of entering a curve, pre-warning lights 2 are respectively arranged on both sides of the starting point of the road, and at least 3 pre-warning lights 2 are arranged between the starting point of the curve and a center line 3 of the curve.
[0022] The pre-warning light 2 is a red, yellow and green tri-color LED light.
[0023] Through this technical solution, when there are no vehicles or pedestrians within 100 meters from the bend to the entrance of the bend, all the pre-warning lights 2 on the road bend are controlled by the controller to emit green light;
[0024] When a vehicle on one side is expected to enter 100 meters before the curve, the microwave radar sensor 1 detects the pre-entering vehicle, and the pre-warning light 2 on the other side of the curve is displayed as a yellow light. At the same time, the microwave radar sensor 1 on the same side of the curve receives the vehicle driving data towards the direction of the curve. When the vehicle enters the curve, the pre-warning light 2 on the other side of the curve is displayed as a red light. At the same time, when the vehicle passes the center line 3 of the curve and there is no vehicle behind, the red light changes to green. If there are other vehicles behind, the color of the red, green and yellow lights is adjusted according to the distance of the other vehicles.
[0025] By setting the above-mentioned pre-warning device, the vehicle entering the curve can promptly know whether there are vehicles entering on the other side of the curve, make driving adjustments, and ensure road driving safety.
