Abstract
The present invention discloses a highway anti-collision early warning system. The system comprises a monitoring camera, a range measurer and a plurality of warning lights, the warning lights are installed at the roadside of the highway, and the distance between two adjacent warning lights is not larger than 50m. The highway anti-collision early warning system is characterized in that: the monitoring camera and the range measurer are configured to monitor a vehicle driving on the highway, the speed of two adjacent vehicles at the front and the back and the distance between the two vehicles in real time, and when it is discovered that the distance between the front vehicle and the back vehicle is smaller than a safe distance, the flashing position is located behind the front vehicle and the warning light located at front of the back vehicle is configured to perform warning for the back vehicle.
Description
Technical field
The invention belongs to technical field of transportation, relate in particular to a kind of highway collision early warning system.
Background technology
Currently for the vehicle travelling on a highway, if necessary to anticollision early warning be carried out to it, typically all by means of the collision avoidance system that vehicle itself is entrained.But vehicle collision avoidance system is simply just popularized in recent years on some vehicles, and mostly luxury car, ordinary vehicle type rarely has installs such device person.With the development of social economy, the popularization of vehicle, particularly highway driving have become as safely the problem having increasing need for noticing, particularly in some Dangerous Areas, due to the awareness of safety of environment restriction and driver, along with the increase of vehicle flowrate, cause the accident and take place frequently.In addition to strengthening the safety education to vehicle operator, also it is necessary that specific road section on a highway installs preventative alarming device, or transformation and upgrade is carried out to the facility of specific road section, to reduce the incidence of security incident.
Content of the invention
The invention discloses a kind of specific road section for being arranged on highway, play warning function, to reduce the highway collision early warning system of accident rate.
Particularly, present invention employs technical scheme below：
A kind of highway collision early warning system, including monitoring camera, rangefinder and multiple warning lamp, highway roadside installed by plurality of warning lamp, it is preferably mounted inside the guardrail of one or both sides, interval between two neighboring warning lamp is less than 50 meters, more preferably no more than 20 meters, most preferably not more than 10 meters, it is characterized in that, monitoring camera and rangefinder are used for carrying out monitor in real time to the distance between the vehicle of running on expressway and the speed of two adjacent in front and back cars and two cars, when finding the distance between rear car and front truck less than safe distance, warning lamp after front truck and before rear car for the flicker position warns to rear car.It is further preferred that monitoring camera and rangefinder monitor before and after two cars relative velocity, when find rear car accelerate with respect to the relative velocity of front truck and distance below safe distance when, warning lamp after front truck and before rear car for the flicker position warns to rear car.
The highway collision early warning system of the present invention can very easily be transformed on existing freeway infrastructure, on hardware, only need to test the speed in existing highway, on the basis of monitoring system, corresponding warning lamp is installed additional on anticollision barrier, in addition on software, only need to existing monitoring software is updated accordingly, load corresponding software module.
Brief description
Fig. 1 is the schematic diagram of the highway collision early warning system of the present invention.
Wherein 1 is monitoring camera, and 2 is rangefinder, and 3 is warning lamp, and 4 is guardrail.
Specific embodiment
In view of highway vehicle flowrate increases, particularly in the problem that particular risk section accident rate is high, the present invention develops a kind of highway collision early warning system, installs in specific road section, plays warning vehicle, reduces the effect of accident rate.
On a highway, it is limited to specific environmental agents, or some old highways, it is limited to design defect then, often become accident district occurred frequently.For example in some Chang Po gentle slope sections, when cart goes up a slope, start can be very fast for speed, but when push up near slope, power is not good leads to speed to decline, and the dolly at rear often power performance well, leads to rear-end collision with car is too fast.Also have some extreme terrain sections it is desirable to vehicle deceleration, but when current vehicle is normally slowed down, rear car closely leads to reaction not in time rear-end collision to occur with car excessively.In these sections, existing scheme often lays deceleration strip or other prompting facility in All-terrain, but effect is not evident.For example in the case of All-terrain laying deceleration strip, when starting to run into deceleration strip, driver is easily noted that, but easily produces mental fatigue, has an accident on the contrary at the end of section is fast.The early warning system of present invention exploitation, autotelic easily dispatching a car for latent defect is reminded, it can be avoided that this mental fatigue.
As shown in Figure 1, the highway collision early warning system of the present invention, on existing highway existing monitoring camera 1, on the basis of rangefinder 2, multiple warning lamps 3 are installed additional on freeway guardrail 4, install corresponding functional module more in the controls additional, you can realize the function of the present invention.Warning lamp may be mounted inside the guardrail of one or both sides, and in addition to as anti-collision warning warning lamp, may also operate as has a lot of social connections warns the effect of paillette, or anticollision early warning warning lamp bulb just may be mounted at original warning in paillette.Interval between two neighboring warning lamp is less than 50 meters, i.e. the safe distance in two workshops that highway requires, more preferably no more than 20 meters, most preferably not more than 10 meters.It will be appreciated that accompanying drawing be only the principle of the invention is made schematically illustrate, do not represent actual conditions, its ratio is also only the reason understand and has made corresponding adjustment.
As shown in the figure, monitoring camera and rangefinder are used for carrying out monitor in real time to the distance between the vehicle of running on expressway and the speed of two adjacent in front and back cars and two cars, when finding the distance between rear car and front truck less than safe distance, warning lamp after front truck and before rear car for the flicker position warns to rear car.More preferably, the relative velocity of two cars before and after monitoring camera and rangefinder supervision, when discovery rear car accelerates with respect to the relative velocity of front truck, i.e. front truck is slack-off or during rear vehicle speed increase, and when distance is below safe distance, warning lamp after front truck and before rear car for the flicker position warns to rear car.
The highway collision early warning system of the present invention can very easily be transformed on existing freeway infrastructure, on hardware, only need to test the speed in existing highway, on the basis of monitoring system, corresponding warning lamp is installed additional on anticollision barrier, in addition on software, only need to existing monitoring software is updated accordingly, load corresponding software module.
Above in conjunction with accompanying drawing, embodiments of the present invention are described in detail, but the invention is not restricted to above-mentioned embodiment, in the ken that art those of ordinary skill possesses, can also make a variety of changes on the premise of without departing from present inventive concept.
