Description

Technical Field

[0001] The utility model relates to a warning device for oncoming vehicles on a curved road. Background Art

[0002] For a long time, accidents of collision with oncoming vehicles when meeting on a curve have occurred frequently, especially on mountain roads. Due to the influence of various practical conditions, on roads with many curved sections and sharp turns, the driver's vision is obstructed and it is difficult for the driver to perceive the situation of oncoming vehicles. Although convex mirrors are often installed at curves to expand the driving field of vision, the use of convex mirrors at curves is limited, the reflection angle is limited, and the placement position is easily offset and the mirror body is damaged. When affected by weather conditions such as rain, fog and snow, the image is unclear and not obvious, resulting in blind spots in the driving vision, which ultimately leads to vehicle accidents.

[0024] like Figure 1-4As shown, a warning device for oncoming vehicles on a curve includes a first warning mechanism and a second warning mechanism, wherein the first warning mechanism includes a first controller 11, a first geomagnetic sensor 12, a first delayed power-off relay 13, a first warning light 14 and a first power supply device 15, wherein the first geomagnetic sensor 12 and the first delayed power-off relay 13 are respectively connected to the first controller 11, the first geomagnetic sensor 12 feeds back the detected vehicle situation to the first controller 11, and the first controller 11 controls the first delayed relay 13 according to the feedback of the first geomagnetic sensor 12, and the first warning light 14 and the first delayed power-off relay 13 are respectively connected to the first controller 11. The first controller 11 controls the first delay relay 13, so that the first warning light 14 is lit and delayed to go out or not lit, the first power supply device 15 is connected to the first controller 11, the first delay power-off relay 13 and the first warning light 14, and the first power supply device 15 is used to power the first controller 11, the first delay power-off relay 13 and the first warning light 14, and the second warning mechanism includes a second controller 21, a second geomagnetic sensor 22, a second delay power-off relay 23, a second warning light 24 and a second power supply device 25, the second geomagnetic sensor 22 and the second delay power-off relay The electrical appliances 23 are respectively connected to the second controller 21, the second geomagnetic sensor 22 feeds back the detected vehicle conditions to the second controller 21, and the second controller 21 controls the second delay relay 23 according to the feedback of the second geomagnetic sensor 22.

The first geomagnetic sensor 12 and the second geomagnetic sensor 22 are respectively arranged at the entrances at both ends of the meeting road 3, and are respectively used to monitor the vehicle conditions at the entrances at both ends. When the first geomagnetic sensor 12 and the second geomagnetic sensor 22 detect that a vehicle enters its sensing area, the signal will be transmitted to the corresponding controller.

The meeting road 3 is provided with a first warning light 14 on the left side of the entrance where the second geomagnetic sensor 22 is located.

[0025] The first geomagnetic sensor 12 is connected to the first controller 11 via a wireless signal, and the second geomagnetic sensor 22 is connected to the second controller 21 via a wireless signal. The geomagnetic coil in the geomagnetic sensor can monitor metal objects and send a signal to the controller when the metal object enters its sensing area.

[0026] In actual application, the first geomagnetic sensor 12 and the second geomagnetic sensor 22 used in the utility model can be respectively provided with a plurality of them, so as to increase the monitoring area of ​​the oncoming road 3. When any geomagnetic sensor detects a vehicle, it will transmit the signal to the corresponding controller and control the corresponding warning light to light up, so as to prevent the oncoming vehicle from misleading the geomagnetic sensor when two or more oncoming vehicles are close to the vehicle. Due to the influence of the cycle period of the delayed power-off relay, the warning light stops lighting when the rear vehicle is about to turn, thereby causing the driver to misjudge the oncoming vehicle information, thereby enhancing the working accuracy of the warning device. When adding a geomagnetic sensor, the geomagnetic sensor farthest from the turn must meet the requirement that the distance between the boundary of the sensing area and the turn shall not be less than 56m.

[0027] The first power supply device 15 and the second power supply device 25 both include a battery 51, a solar photovoltaic controller 52 and a solar panel 53.

When wiring, the solar panel 53 is connected to the solar energy input terminal, the battery 51 is connected to the battery input terminal, and the controller, the delayed power-off relay and the warning light are connected to the load output terminal.

[0029] Warning lights use yellow light with a longer wavelength, less prone to scattering, and longer transmission distance.

[0030] During on-site construction, the first controller 11, the first delayed power-off relay 13, the battery 51 of the first power supply device 15, and the solar photovoltaic controller 52 can be arranged in the first control box 16 and fixed next to the first warning light 14, and the solar panel 53 of the first power supply device 15 can be fixed on the top outside the first control box 16 to receive sunlight for power generation; the second controller 21, the second delayed power-off relay 23, the battery 51 of the second power supply device 25, and the solar photovoltaic controller 52 can be arranged in the second control box 26 and fixed next to the second warning light 24, and the solar panel 53 of the second power supply device 25 can be fixed on the top outside the second control box 26 to receive sunlight for power generation.

[0031] The working principle of the utility model is as follows:

[0032] The driver of the vehicle in the left lane drives towards the first geomagnetic sensor 12. When the vehicle enters the sensing range of the first geomagnetic sensor 12, the geomagnetic coil in the first geomagnetic sensor 12 senses the metal object (vehicle), triggering the first geomagnetic sensor 12 to generate a control signal and send it to the first controller 11. After receiving the signal instruction, the first controller 11 triggers the first delayed power-off relay 13 to switch from the normally closed contact to the normally open contact and maintain this state. At present, the circuit switch of the first warning light 14 is in the closed state, and the first warning light 14 is powered on and emits a bright light. At this time, if there is a vehicle driving in the right lane, the driver of the right lane can When the first warning light 14 is in the luminous state, it is judged that there is a vehicle coming from the opposite direction in the left lane, and corresponding measures can be taken in time to prevent a collision when meeting the two vehicles; when the driver of the vehicle in the left lane completely leaves the sensing area of ​​the first geomagnetic sensor 12, the first geomagnetic sensor 12 stops sensing, and the first delayed power-off relay 13 starts delayed action, and the contact continues to maintain the state. After the delayed action of the first delayed power-off relay 13 ends, the normally open contact returns to the normally closed contact. At this time, the circuit switch of the first warning light 14 is in the disconnected state, the first warning light 14 is powered off and stops emitting light, and the circuit system ends its work and waits for the next cycle.

[0033] The warning device on the right lane works in the same way: the driver of the vehicle in the right lane drives towards the second geomagnetic sensor 22. When the vehicle enters the sensing range of the second geomagnetic sensor 22, the geomagnetic coil in the second geomagnetic sensor 22 senses the metal object (vehicle), triggering the second geomagnetic sensor 22 to generate a control signal and send it to the second controller 21. After receiving the signal instruction, the second controller 121 triggers the second delayed power-off relay 23 to switch from the normally closed contact to the normally open contact and maintain this state. At present, the circuit switch of the second warning light 24 is in the closed state, and the second warning light 24 is energized to emit a bright light. At this time, if there is a vehicle driving in the left lane, the left lane The driver of the side lane can judge that there is a vehicle coming from the opposite direction in the right lane by the fact that the second warning light 24 is in the luminous state, and can take corresponding measures in time to prevent a collision when the vehicle meets the vehicle; when the driver of the right lane completely leaves the sensing area of ​​the second geomagnetic sensor 22, the second geomagnetic sensor 22 stops sensing, the second delayed power-off relay 23 starts delayed action, and the contact continues to maintain the state. After the delayed action of the second delayed power-off relay 23 ends, the normally open contact returns to the normally closed contact. At this time, the circuit switch of the second warning light 24 is in the disconnected state, the second warning light 24 is powered off and stops emitting light, and the circuit system ends its work and waits for the next cycle.

Obviously, the present invention is not limited to the above embodiments, and there are many variations.
