Specific embodiment
In order to more clearly state the present invention, the present invention is further described below in conjunction with the accompanying drawings, it is necessary to pay attention to
It is, during description, using for representing the suffix of such as " module ", " component " or " unit " of element only for more
The good description present invention.Itself there is no any specific meaning；Therefore " module ", " component " or " unit " three can mix
It uses.
Vehicle high-speed safety early warning device provided by the present invention may be mounted in driver's cabin, come in various manners real
It applies, such as in guider, can also be applied to the terminal of other fixed types.
In the present embodiment, " emergency " 11 and " slowly exercising " 12 buttons, driver's root are provided on warning module 1
The selection of pattern, in the case where vehicle is normally exercised, entire vehicle are carried out according to the environment of current outside and the enforcement state of vehicle
High-speed secure prior-warning device normally enables, and the visual field is wide at this time, and visibility is high, and driver can observe directly the enforcement of vehicle
Situation finds that front goes wrong and can react in time；But when under special circumstances, such as greasy weather, rainy day or ice and snow weather
Under the conditions of, the visual field is small, visibility bottom or in the case where vehicle goes wrong, and driver carries out pattern according to present case
Selection, useful range of the invention are 300 meters to 1500 meters, have different distance ranges according to the difference of external environment
It is different.
When driving environment is undesirable, such as under ice and snow weather, after driver selects slow enforcement pattern, warning module 1 is sent out
Sending instruction, locating module 2 is determined after receiving the instruction of warning module 1 according to GPS to locating module 2 and distance analysis module 3
Position, and the speed information of highway and the running velocity of vehicle itself residing for obtaining from network, and by these information
Passing to distance analysis module 3, distance analysis module 3, which receives, calculates minimum safe distance after the information of locating module 2, and with
Then minimum safe distance utilizes range sensor as threshold value（Active RFID technology）To between front vehicle and this vehicle away from
From being monitored, when distance between the two is less than threshold value, the warning module 1 in front vehicle sends warning and reminds rear vehicle
There is accident in front of, pay attention to slow down, while the warning module 1 on this vehicle can also make warning and remind driver rear
There is vehicle arriving, pay attention to avoiding.
When vehicle failure can not move ahead when driver select emergency mode after, warning module 1 send instructions to calmly
Position module 2 and distance analysis module 3, locating module 2 are positioned after receiving the instruction of warning module 1 according to GPS, and from net
The speed information of highway residing for being obtained on network, and these information are passed into distance analysis module 3, distance analysis module 3
Minimum safe distance is calculated after receiving the information of locating module 2, and using minimum safe distance as threshold value, then using active
RFID technique is monitored the distance between front vehicle and this vehicle, when distance between the two is less than threshold value, rear vehicle
Warning module 1 on, which sends warning and reminds in front of front vehicle, accident, pays attention to slow down, while in front vehicles
Prior-warning device 1 can also make warning driver rear is reminded to have vehicle arriving, pays attention to avoidance.
In the present embodiment, GPS module uses the range information and correct time of multiple satellites for the positioning of position
Information and pair with the Information application triangulation that calculates, it is three-dimensional current so as to be calculated according to longitude, latitude and pin-point accuracy
Location information, and the max speed on this highway is obtained by network；Distance analysis module 3 obtains current vehicle
Speed information simultaneously calculates minimum safe distance after receiving the information that locating module 2 is sent, and collection may be employed in specific embodiment
Into circuit, digital signal processing device, one kind in Programmadle logic device, microprocessor is calculated；Then using has
Source RFID technologies, frequency carry out long distance monitoringv using the radio-frequency technique of 2.45GHz；Warning side used by prior-warning device 1
Formula includes voice prompt and light prompt, and informs the distance between two vehicle of front vehicle driver, and gradual with distance
It furthers light prompt and voice prompt is gradually strengthened, after front vehicle is more than front front vehicles, prior-warning device is automatically closed.
Under slow enforcement state, if being 200 meters in rainy day visual field visibility, it is 60km/h that front vehicles, which drive speed, this height
The maximum speed of fast highway is 110km/h, calculates the safe distance of vehicle as 300m, in order to ensure driving safety, distance point
Analysis module obtains minimum safe distance as 500m, and beyond the distance between two vehicles is 500 meters, alarming device is failure to actuate；When two
When the distance between vehicle reaches the threshold value of 500m, alarming device starts voice promotion and light prompt；When the distance between two vehicles
During less than 300m, alarming device is reminded strongly；After front vehicle is more than front vehicles, alarming device stops warning function, tightly
Anxious operation principle is identical with slowly enforcement state, and only minimum safe distance is shorter, repeats no more herein.
The present invention method of work be：Driver is selected according to the enforcement state and external environment of vehicle on warning module
State, if vehicle is normally exercised, whole device is served only for receiving the signal that other vehicles are sent；If external environment is severe, such as
Ice and snow weather, driver need the slow down in high speed, press the slow enforcement button on warning module, locating module
The information such as horse back positioning vehicle present position and residing highway, and these information are passed into distance analysis module；
After distance analysis module receives these information, minimum safe distance, and the distance between two vehicles constantly before and after monitoring are calculated,
When the distance between two vehicles be less than minimum safe distance when, control warning module warn, warning include sound warn or
Light warning.
When, since failure causes vehicle not continue on a highway, driver presses early warning in driving procedure
Danger button in module, operation principle is identical with slowly enforcement pattern, and it is no longer repeated herein.
Advantage of the invention is that：
1）Driver can independently be selected according to extraneous situation, and more fitting is actual, the common detection device than on the market
It is more reliable and more stable；
2）Different patterns is had according to different enforcement states, so as to meet the needs of driver is to different conditions；
3）The present invention can be attached on different mobile units, applied widely；
4）After early warning range is walked out, warning, intelligentized control method is automatically closed in warning module.
Disclosed above is only several specific embodiments of the present invention, but the present invention is not limited to this, any ability
What the technical staff in domain can think variation should all fall into protection scope of the present invention.
