Description

Technical Field

[0001] The invention relates to the technical field of road traffic safety, and in particular to a highway sight line guiding system and method. Background Art

[0002] At present, my country has not yet achieved full lighting coverage on expressways and some national and provincial trunk roads. When a motor vehicle is driving at high speed, the driver of the motor vehicle obtains information about the road ahead by capturing the headlights or natural light reflected by environmental objects with the naked eye. Under good lighting conditions, the driver's eyes can obtain sufficient safe foresight distance combined with the guidance of road markings, and take various countermeasures in advance through sufficient safe foresight distance. When at a fork in the road or a section with a safe speed limit, due to sudden changes in weather conditions, such as at night, foggy days, and rainstorms, the visibility is reduced, and the braking time for dealing with emergencies is also reduced accordingly. In addition, the pollution of road markings can easily cause motor vehicles to go in the opposite direction, speed or slow down, resulting in untimely braking and running off the road or being rear-ended by the following vehicle. For the safety of vehicles on the road, it is particularly important to know the direction of the road ahead in advance and grasp the speed limit standards of the section.

[0003] In recent years, road driving guidance methods have emerged, which are set up on the shoulders of roads and other places to actively illuminate the road sections to indicate to drivers the road sections they should pay attention to. Among them, the flashing light (synchronous flashing at a fixed frequency) and anti-rear-end collision light (the flashing light turns to a constant warning after a car passes, and returns to the flashing state after a certain number of seconds when there is no car).

[0004] The existing flashing light mode is shown in Chinese utility model patent CN209907240U "A temporary attached active luminous contour marker device for a highway". This type of equipment only has the function of flashing at a fixed frequency, and cannot interact with the driver in a targeted and intuitive manner regarding vehicle speed control, driving direction, etc.; the existing anti-rear-end collision light mode is shown in Chinese utility model patent CN203807974U "A fog zone induction lamp installed on the side of a highway". The light mode is a unique light mode for foggy days, rainy days, etc., which allows the driver to confirm the distance to the vehicle in front when the seeing conditions are not high, but it still cannot interact with the driver in a targeted and intuitive manner regarding vehicle speed control, driving direction, etc.

[0005] In summary, the existing technologies all adopt the synchronous flashing lighting function, and do not consider the use of large-scale deployment of highway roadside active lighting sight induction devices to provide scientific and reasonable display lighting effects in combination with the needs of road traffic management. It is impossible to achieve functions such as road driving direction guidance and road speed difference prompts through different working modes realized by a variety of light combinations. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a highway sight line guidance system and method.

[0007] The objective of the present invention is achieved through the following technical solutions: a highway sight guidance system, comprising a sensor module, a communication module, a control module, a light source assembly and a power module, the power module being used to provide power input, the sensor module being electrically connected to the input end of the control module through the communication module, the sensor module being used to detect the running direction and speed of the vehicle, and the output end of the control module being electrically connected to the light source assembly.

[0008] A highway sight line guiding method, comprising the above-mentioned highway sight line guiding system, further comprising the following steps:

[0009] S1: When the vehicle enters the detection range of the sensor module, the sensor module measures the running direction and speed of the vehicle and transmits it to the control module through the communication module;

[0010] S2: The control module analyzes the data fed back by the sensor module to determine whether the vehicle is traveling in the wrong direction or at a different speed;

[0011] S3: If the vehicle is traveling in the wrong direction or at a different speed, the control module controls the light source assembly to start and emits a warning light signal according to the wrong direction or different speed warning light logic;

[0012] S4: The sensor module continuously monitors the road section. When it detects that a vehicle traveling in the wrong direction or at a different speed leaves the sensing area, the control module controls the light source component to turn off.

[0013] Preferably, in step S2, the sensor module transmits electromagnetic waves and receives reflected waves, and then determines the moving direction and speed of the vehicle based on the Doppler effect.

[0014] Preferably, in step S3, when the reflected wave shows that the vehicle is moving in the opposite direction to the specified direction of the road, it is determined to be reverse driving, and the control module controls the light source assembly to flash alternately at intervals according to the set luminous intensity and frequency, and the luminous direction is opposite to the vehicle's driving direction.

[0015] Preferably, in step S3, when the sensor module detects that the driving speed does not match the prescribed speed of the road, the control module controls the light source components to light up in sequence at the prescribed speed.

[0016] The present invention has the following advantages: the present invention measures the running direction and speed of the vehicle through the sensor module. When the vehicle is traveling in the opposite direction or at a different speed, the control module controls the light source component to start, and sends out a warning light signal according to the logic of the opposite direction or different speed warning light. Therefore, without distracting the driver's attention, the driver can quickly judge the driving direction and speed according to the light prompt of the light source component, thereby assisting the driver to drive safely.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] In this embodiment, if Figure 1 As shown, a highway sight guidance system includes a sensor module 2, a communication module 3, a control module 4, a light source assembly 5 and a power module 1. The power module 1 is used to provide power input. The sensor module 2 is electrically connected to the input end of the control module 4 through the communication module 3. The sensor module 2 is used to detect the running direction and speed of the vehicle. The output end of the control module 4 is electrically connected to the light source assembly 5. The running direction and speed of the vehicle are measured by the sensor module 2. When the vehicle is driving in the reverse direction or at a different speed, the control module 4 controls the light source assembly 5 to start and emits a warning light signal according to the reverse or different speed warning light logic, so that the driver can quickly judge the driving behavior and the speed according to the light prompt of the light source assembly 5 without distracting the driver's attention, so as to assist the driver to drive safely.

[0027] A highway sightline guidance method, such as Figure 2 As shown, the highway sight line guidance system includes the above-mentioned steps, and further includes the following steps:

[0028] S1: When the vehicle enters the detection range of the sensor module 2, the sensor module 2 measures the running direction and speed of the vehicle and transmits it to the control module 4 through the communication module 3;

[0029] S2: The control module 4 analyzes the data fed back by the sensor module 2 to determine whether the vehicle is traveling in the opposite direction or at a different speed; further, in step S2, the sensor module 2 emits electromagnetic waves and receives reflected waves, and then determines the moving direction and speed of the vehicle based on the Doppler effect.

[0030] S3: If the vehicle is traveling in the wrong direction or at a different speed, the control module 4 controls the light source assembly 5 to start and emit a warning light signal according to the wrong direction or different speed warning light logic;

[0031] S4: The sensor module 2 continuously monitors the road section. When it detects that a vehicle traveling in the opposite direction or at a different speed has left the sensing area, the control module 4 controls the light source assembly 5 to turn off. Specifically, in the present invention, the luminous time refers to the time that the light source assembly 5 is continuously lit; the luminous switching time refers to the time until the next light source assembly 5 is arranged adjacent to the light source assembly 5 in the direction of travel of the light source assembly 5; the luminous cycle time refers to the time from when a light source assembly 5 turns off to when it turns on (the lighting interval is expressed as a multiple of the luminous time), and the luminous switching time expressed by speed is called the luminous speed. The luminous time can be obtained by dividing the installation interval of the light source assembly 5 by the guide speed of the road section. For example, in order to obtain a guide speed of 100km / h through light source assemblies 5 installed at intervals of 10m, the following formula can be used to obtain the luminous time of 0.36s to light up the lights in sequence:

[0032]

[0033] When a road section needs to set a constant maximum guidance speed of 100 km / h due to safety management needs, the light-emitting devices installed at intervals of 10 meters are lit in the direction of overtaking at a speed of 0.36s. The driver controls the vehicle speed based on the visual response stimulated by the light speed of the device as a reference, so that the vehicle is guided and travels at a safe speed. That is to say, in step S3, when the reflected wave shows that the vehicle is moving in the opposite direction to the specified direction of the road, it is determined to be reverse driving, and the control module 4 controls the light source assembly 5 to flash alternately at intervals according to the set light intensity and frequency, and the light direction is opposite to the vehicle's driving direction, as shown in Table 1. Table 1

[0034]

[0035]

[0036] Among them, ■ means the light is on, and □ means the light is off.

[0037] When the sensor module 2 detects that the driving speed does not match the road speed, the control module 4 controls the light source assembly 5 to light up in sequence at the prescribed speed, as shown in Table 2.

[0038] Table 2

[0039]

[0040] Specifically, the speed of light is set to be greater than or equal to the speed of other reference objects in the driver's field of view, thereby giving the driver a greater sense of speed; conversely, the speed of light is set to be equal to or lower than other reference objects, thereby giving the driver a smaller sense of speed.

[0041] In addition, if an abnormal situation such as a sudden accident occurs ahead on the road, the light source assembly 5 can emit light in the opposite direction of the vehicle's travel to promote deceleration and prompt the vehicle to adjust its travel in the opposite direction.

[0042] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
