Specifically, with the nearly 30 years high speed developments of China's highway, when the mileage number of highway and operation
Between be continuously increased, the pavement diseases such as pit slot, crack persistently occur, highway maintain task it is increasingly heavy.And
Along with the rapid development of China's economy, car ownership is continuously improved, and the traffic capacity of the existing highway in part cannot
Meet transport need, the reconstruction and extension project of highway is also increasing.Above-mentioned factor promotes highway construction area constantly to increase
Add.Highway maintenance construction, which is generally taken, occupies part lane, the mode constructed when being open to traffic, due to express-road vehicle running speed
The features such as fast is spent, causing current construction operation area, security issues become increasingly urgent.According to " highway maintenance safety work regulation "
The regulation such as (JTG H30-2015) specifications, current construction area safety measure are mainly arranged Operation control area, use safety devices
Deng, wherein safety devices mainly have temporary sign, interim graticule, traffic bucket, water horse etc., in addition to this also need setting traffic guiding
Personnel.Currently used traffic safety facilities majority belongs to passive type security protection and early warning, can not actively issue early warning in time

The abnormal drivings behavior such as construction area is not found, and construction area operating personnel is difficult to find in time, and adopts an effective measure, easily
It causes casualties and is damaged with facility.
Based on this, the embodiment of the present invention one provides the method for construction of the highway region security early warning, for solving
State technical problem.
In the following, being carried out in conjunction with Fig. 1 to the method for the early warning of construction of the highway region security that the embodiment of the present invention one provides
It is discussed in detail:
S110, judge whether there is target vehicle to drive into warning area；
Specifically, in construction of the highway region, as long as being defaulted as existing safe hidden into the target vehicle in warning area
The vehicle namely the embodiment of the present invention of trouble judge whether target vehicle enters in warning area first.Certainly judging it
Before, the embodiment of the invention also includes: in the warning area internal labeling critical point；Wherein, the critical point includes at least: vehicle is sailed
Enter critical point, vehicle safety speed critical point and vehicular safety distance critical point.Wherein, the vehicle drives into critical point, vehicle
Safe speed critical point and vehicular safety distance critical point are sequentially reduced relative to the distance in construction of the highway region.In other words,
When normal section of the target vehicle by road in front of construction area drives into warning and go interior, critical point, vehicle successively are driven by vehicle
Safe speed critical point and vehicular safety distance critical point.
At this point, after the warning area internal labeling critical point, it is described to judge whether there is target vehicle to drive into tool in warning area
Body includes:
It judges whether there is target vehicle and critical point is driven by the vehicle；
If passing through, judgement has target vehicle to drive into the warning area.
Wherein, critical point being driven by the vehicle for how to judge whether there is target vehicle, can be sentenced by a variety of
Disconnected mode is judged, for example, it may be driving into setting sensor at critical point in vehicle, is implemented when there is vehicle to pass through
Induction, and induction result is generated into signal and is transmitted to processing terminal, it is also possible to drive into setting camera at critical point in vehicle,
Picture catching is carried out when there is vehicle to pass through, and will be captured image generation signal and be transmitted to processing terminal etc..It is worth mentioning that
The critical point present invention is driven into without limitation by the vehicle for how to judge whether there is target vehicle, as long as can be realized pair
Whether target vehicle, which drives into critical point by the vehicle, is judged, then is suitable for the present invention.
It is understood that is then indicated when vehicle drives into critical point by vehicle target vehicle drive into warning go it is interior, at this time
Execute following step:
S120, if so, then obtaining the first vehicle speed information for driving into the target vehicle in the warning area；
Wherein, to be the target vehicle described in the t1 moment drive into critical point and described in the vehicle to first vehicle speed information
Vehicle speed information between vehicle safety speed critical point, and the t1 moment can be target vehicle driven into the vehicle it is critical
Any time between point and the vehicle safety speed critical point in driving process.Meanwhile the operation in notice construction area
Personnel have target vehicle to travel to warning area at this time.For advice method, can be shown by voice broadcast or screen
Mode is prompted, for example, in construction area install loudspeaker and/screen display, the loudspeaker and/screen display and
Processing terminal is communicated, when detect target vehicle enter warning area detection signal be transmitted to loudspeaker and/screen
When on display, voice broadcast is carried out by loudspeaker, and screen is carried out by screen display and is shown.
S130, judge whether the target vehicle needs to carry out first time safe early warning according to first vehicle speed information；
S140, if so, carry out first time safe early warning；
Wherein, for driving into the target carriage travelled between critical point and the vehicle safety speed critical point in the vehicle
For, the considerations of due to safety, target vehicle enters after warning goes, and the travel speed of target vehicle is to need to pass in real time
Subtract namely target vehicle enter warning go rear speed should be it is lower and lower, only in this way could target vehicle be expert at
Travel speed has already decreased to safe speed when sailing to vehicle safety speed critical point.In this regard, described according to first speed
Information judges whether the target vehicle needs to carry out first time safe early warning and specifically include:
It obtains the target vehicle described in the t2 moment and drives into critical point and the vehicle safety speed critical point in the vehicle
Between the second vehicle speed information；
Judge whether second vehicle speed information is less than first vehicle speed information；
If it is not, then carrying out first time safe early warning.
Likewise, the t2 moment, which can be target vehicle, drives into critical point and the vehicle safety speed in the vehicle
Any time between critical point in driving process.But the t2 moment is the t1 moment later moment in time namely t1 moment
It is the first moment at the t2 moment, for example the t1 moment is 9:30:17 in afternoon (30 divide 17 seconds when 9), then the t2 moment can be down
Noon 9:30:25 (30 divide 25 seconds when 9), for t1 moment and t2 moment be specifically target vehicle the vehicle drive into critical point and
At which between the vehicle safety speed critical point in driving process, the embodiment of the present invention is not limited to, as long as mesh at moment
It marks vehicle and drives into any time between critical point and the vehicle safety speed critical point in driving process in the vehicle, then
It is suitable for the present invention.
When judging that second vehicle speed information is greater than first vehicle speed information, then it represents that target vehicle enters warning area
After interior, do not slow down, then carry out first time safe early warning at this time, which can be understood as " target vehicle
Do not slow down in first interval section after entering warning area " warning message.It should be noted that implementing in the present invention
In example, driving into the region travelled between critical point and the vehicle safety speed critical point in the vehicle can be first interval
Section, the region travelled between the vehicular safety distance critical point and the vehicle safety speed critical point can be second interval
Section.About the alarm mode of first time early warning, can be prompted in such a way that voice broadcast or screen are shown, such as
Installation loudspeaker and/screen display in construction area, the loudspeaker and/screen display and processing terminal are communicated, when
When detecting that target vehicle enters warning area and unmoderated detection signal is transmitted on loudspeaker and/screen display, lead to
It crosses loudspeaker and carries out voice broadcast, and screen is carried out by screen display and is shown.
For as another embodiment, the vehicle described in the target vehicle drives into critical point and the vehicle safety speed
It, can also be by only passing through vehicle safety speed critical point Shi Jinhang to the first vehicle speed information after being travelled between critical point
Judgement, in other words, for vehicle safety speed critical point, speed when target vehicle passes through vehicle safety speed critical point
It is to have to lower than a certain safe speed threshold value, just indicates that traveling of the target vehicle in second interval section is safe, that is,
The a certain safe speed threshold value is it is to be understood that when target vehicle is being travelled to vehicle safety speed critical point constantly if speed
Higher than the safe speed threshold value, then the target vehicle can not be braked in second interval section until vehicle stops.As
Another embodiment judges whether the target vehicle needs according to first vehicle speed information described in the embodiment of the present invention
Carry out first time safe early warning specifically include: judge first vehicle speed information at the vehicle safety speed critical point whether
Less than safe speed threshold value；If it is not, then carrying out first time safe early warning.
Certainly, in embodiments of the present invention, above two embodiment can also combine, namely judge the second speed letter
Breath also can determine whether second vehicle speed information in institute after any time in first interval section is less than first vehicle speed information
It states and whether is less than safe speed threshold value at vehicle safety speed critical point；If it is not, equally carrying out safe early warning.
When sailing out of first interval section for target vehicle and entering second interval section, in order to avoid there is target vehicle first
Really being slowed down in segment, and speed has had fallen to secure threshold when by vehicle safety speed critical point
Speed, and when vehicle driving to second interval section, driver improves speed again, and the embodiment of the present invention is passed through in target vehicle
It crosses vehicle safety speed critical point to enter after second interval section, further includes: obtain the target vehicle described in the t3 moment described
Third vehicle speed information in second interval section；Judge whether second vehicle speed information is less than the secure threshold speed；If it is not,
Ultimate early warning is then carried out, and informs that the staff in the construction of the highway region leaves the construction of the highway region.
S150, the target vehicle obtained in the warning area are currently located lane information；
In first interval section, the current lane information where target vehicle can be obtained in real time, which can be
" first lane " or " second lane "；Because in construction of the highway section, by construction area often need to occupy vehicle it is normal
The lane of traveling, for example, on first lane section break down, then just need to the failure section on first lane into
Row is repaired, and construction area has just been located on first lane at this time, while warning area is also arranged in company with construction area in the first vehicle
On road.Be into the target vehicle in warning area, for normal should timely change lane, that is, there is the lane of construction area to change
To the lane of non-construction area, and then bypass construction area.For example, target vehicle is altered to the second vehicle from first lane in time
Road.And in the present invention, in order to avoid vehicle operator continues traveling in current lane because not paying attention to or ignoring lane
Safety accident is ultimately caused, lane information is currently located by obtaining the target vehicle in the warning area, to judge
Whether the target vehicle travelled has carried out lane change, namely:
S160, judge whether the target vehicle needs to carry out second of safe early warning according to the lane information；
S170, if so, carry out second of safe early warning；
Specifically, described judge whether the target vehicle needs to carry out second of safety in advance according to the lane information
Police may include:
Obtain the lane information where warning area；
The lane information being currently located to the target vehicle identifies；
Judge whether lane information that the target vehicle is currently located and the lane information where the warning area are same
One lane；
If so, carrying out second of safe early warning.
