Background technology
The present invention is《A kind of highways based on GPS and GSM platforms of CN201620123453 and CN201610087970
Vehicle-mounted group's navigation system》Supplement and extension.
Retrieve national patent storehouse " highway+positioning ", there are hundreds of Patents, and retrieve " highway+centimetre
Level ", one does not all have, and this is that existing e measurement technology means constrain our positioning precision, and on a highway
For 100 kilometers/hour of driving vehicles, the precise positioning of online vehicle is by concerning the final and decisive juncture of personnel.
Existing Moving objects location technological means mainly has:
1. gps satellite is positioned, 50~100 meters of precision;
2. LBS architectures, 10~50 meters of precision;
3. Wi-Fi indoor positionings, 0.10~0.5 meter of of precision
Present technological means is for the static precision coordinate of the earth(Such as base station, basic point), GPS can reach grade, but all need
Permanent positioning time is wanted, big ground level intervisibility satellite monitoring point is more, detection number of times is more, the calculating average value obtained by it
Also more accurate, this is for vehicle commander less than 2 meters, and horizontal spacing is less than 0.5 meter, and the vehicle run at high speed, its positioning means are aobvious
So it is difficult in adapt to.
Equally, for using wave source position LEB architectures, such as mobile phone position, due to the diffraction of ripple, reflection, interference,
The characteristics such as decay can all influence quick, the precise positioning of vehicle.Network mapping polar plot under isomorphism state car-mounted display interface
Jumped as that can occur to dodge, running orbit non-coherent.
When people look up at starry sky, suffer from when seeking high-precision online vehicle positioning technology means, we have ignored one
Important displacement object of reference, that is, under sole highway in itself,
1. highway is built
Modern Large Infrastructure Projects generally employ the static immobilization of national highway construction criteria, CAD design and GPS control nets
(The object being positioned is fixed point non-displacement state), it is designed and positioning precision is all in grade, such as water conservancy, electric power, high ferro,
Highway and bridge etc., such as 4778 meters of Runyang Changjiang Highway Bridges of overall length, employ 19 GPS location network points, error amount
Less than 5 millimeters;Shanghai-Hangzhou, the GPS of Shanghai-Nanjing freeway control net wire total length closure error to be Centimeter Level.
Reference《GBT 18314-2001 global positioning systems(GPS)Specifications of surveys》, the measurement accuracy of highway all exists
Centimeter Level, Fig. 1, Fig. 2, Fig. 3 are certain section of highway CAD design figure and array coordinate figure, are therefrom not difficult to find out its design accuracy
It is grade, moreover, pile coordinate is respectively provided with each section(X,Y), it is static coordinate values.Measurement
Precision is far above the dynamic measurement of people.
In addition, the construction means of modern highway, generally employ pile Site Template pour, slab factory
Modularization integral solder, the method for construction of cast, its quality and precision are greatly improved.
As can be seen here, coordinate is built with highway itself, the precision dynamically positioned as vehicles running on expressway
It is that can reach Centimeter Level(Value containing construction error).

Embodiment
As shown in figure 11 embodiment is specifically described as preferred embodiment:
People have for the detection of conventional high rate road running situation:Built-in type sensor, fixing camera, helicopter boat
Clap, unmanned vehicle is taken photo by plane and satellite such as is taken photo by plane at the technological means, all many defects of generally existing person:
1. pixel
High-definition image is closely related with eye recognition, if using the camera on unmanned vehicle, it is necessary to which problem is smashed in consideration,
So will not be very high using price, corresponding pixel also would not be very high(Typically in several K);
2. focal length
Due to be at a high speed dynamic shoot, it is difficult to fixed point and zoom, so no matter the image that helicopter and unmanned vehicle are taken photo by plane
Will there is a possibility that image blurring;
3. fisheye effect
Due to the optical effect of convex lens, the edge of its wide-angle can all produce the deformation of image;
4. travel limit
No matter helicopter and unmanned vehicle are taken photo by plane, and due to the restriction of fuel, power supply, can all be had space-time limitation, be taken photo by plane
Radius is difficult to over long distances;
5. territory restriction
Due to the flying height limitation that helicopter and unmanned vehicle are taken photo by plane, just it is difficult to fit for the geographical environment on high and steep mountains
With, as well as《Aviation management rules》, it is applicable by very big restriction.In addition, helicopter and unmanned vehicle
The flying height taken photo by plane, is also limited by high-voltage fence, high voltage power transmission and transforming tower is all distributed with along general highway, especially
In both mountain areas, spacing is not suitable with aircraft flight;
6. weather is limited
For taking photo by plane for helicopter and unmanned vehicle, climatic factor is particularly significant, for the wind and snow rainy day, takes photo by plane almost
It is to be difficult to;
7. side light pollution
Because the imaging of convex lens depends on optical effect, it can not be filtered for the light pollution of environment, finally all be imaged on synthesis
On figure;
8. time restriction
Taking photo by plane mostly on daytime for helicopter and unmanned vehicle, can not carry out if at night, especially lack illumination
Flight occasion;
9. color defect
Dependent on the image recognition of optical effect, defect is equally existed on color detection, it is known that the Nature rainbow and
Mirage effect, is due to different medium, the anaclasis of band of density, such as water, air and glass(Convex lens), can all cause
The change of spectral frequency, daylight is when being decomposed into seven colors, the assorted edge of red, orange, yellow, green, indigo, azure, purple, in gradient color, it is difficult to use
Fixed frequency spectrum discerning instrument goes to be distinguish between, and shown in Figure 17 is that erroneous judgement case is punished in foreign countries' traffic caused by image recognition
Example, in the case, car shadow is mistaken for car line ball by monitoring system;
10. cost is limited
Built-in type sensor is then that cost is big, for remote mountain areas, the highway of short of electricity, it is difficult to promotes and safeguards.
It is of the invention then using digitizing solution, by current popular AR(Augmented Reality)Enhancing technology application
In vehicle on highway positioning, all to lack compared with conventional art means for the condition such as region, weather disturbing factor, its imaging,
Positioning precision will be better than the aerial photography effect of helicopter and unmanned vehicle(See Fig. 8, Figure 10, Figure 18).
Three figures are contrasted, the superiority of the present invention is not difficult to find out:
1. mobilism
The present invention uses instant situation, Millisecond refreshing, the technological means of isomorphism homomorphism, may be such that each driver all
Road conditions and self-position along will appreciate that, and Aerial Images will also pass to traffic control center, then led to roughly by station broadcast
Report.Not only the time is upper delayed, and its effect differs greatly.
2. digital quantization
Traditional technological means mostly can only be qualitative, it is difficult to accomplishes quantitative, such as:Certain car breakdown is in highway, its electricity of alarming
Words get to supervision department, and car owner first is just difficult to report for self-position(Especially at night), even on daytime for this
The mark in section, most of driver is also arriving of not necessarily recognizing, so that many times can be delayed, the place for jeopardizing accident
Reason occasions a delay, and the present invention then can a key settle within one second, either monitoring backstage or driver are very clear in itself.
Looked into 3. vehicle is sought
The highway of China covers networking substantially, is robbed for robber, the crime event such as kidnap, once case-involving vehicle drives into high speed,
Public security department wants to find the vehicle in a short time, it is sometimes desirable to employ a tremendous amount of manpower, material resources are along one in shooting data
Checking for the frame of frame one, undoubtedly looks for a needle in a haystack, often futile and return.
The present invention realizes Digital location for driving into each car of highway sluice gate, simply enters car plate ginseng
Number, just quickly can find the vehicle in relevant road segments, even have run out freeway net, can also find the traveling rail of the car
Mark.
First, vehicle tuning on-line
When driving into sluice gate, with RF device(RF)Sluice gate machine, group's navigation system can be activated automatically, initial coordinate (X is established0,
Y0), Fig. 9 is high speed charge station rasterizing positioning realistic picture;Because there is the time, apart from upper difference, each discrepancy
Each gate vehicle, all with unique<Opportunity-distance>Three-dimensional coordinate value (T0,X0,Y0), such as using A1~A6 tracks to roll away from
Track, B1~B6 is drives into track, in T0At the moment, the initial coordinate of its each car is respectively shown in table 1:
Table 1
Conventional truck mileage calculation, employs axle drive method of counting, but during the traveling of actual vehicle, what is walked is plane curve
Shape mileage, so vehicle actual travel mileage is but significantly larger than highway layout mileage.Therefore, using traditional line motion calculation side
Method:Δ S=V Δ t, for centimeter-level positioning standard, its accumulated error is very big, and the present invention utilizes original CAD high speeds
Highway and Automobile Design, the accuracy of manufacture, using body shell length(L values)The method measured, to the actual travel mileage of vehicle,
Implement tuning on-line(See Figure 12);
As it was previously stated, during highway construction, make use of gps satellite static immobilization, first establishing center with array pile coordinate
Line, then in Central Symmetry form, two-way lane is established in two sides to the left and right, is then line successively, isolates and close, therefore,
Isolation anchoring wire, divisional line on highway, closing pier line, or even electrical equipment, street lamp, illumination, the distributing line of control, all with
Center line is parallel in antarafacial, so each section uses gps satellite
Vector positioning, just can establish the neutral conductor trend in the section.
The vehicle of fast running on a highway, its driving trace should be speeded with centerline parallel in theory
(See Fig. 5, Fig. 6), but different from the high ferro that safety coefficient is higher, high ferro has track restriction, and automobile does not have then, and it can be with
Meaning lane change, most accidents are all caused by lane change.
The present invention is front and rear to be each provided with a three-dimensional distance measuring sensor on the axial line of vehicle, according to front and rear X axis two
Isolation and the honest distance measurement value of closing that laser sensor can be fixed to the side of left and right two, determine vehicle axial line and highway center
The antarafacial angle of line(The deviation angle)β value,(X、Y)The parameters such as coordinate values, speed, distance travelled,
Different from the positioning of traditional gps satellite, LBS architectures, the present invention is real-time online data sampling, the ripple without the former two
Source property precision disturbing factor, when vehicle drives into highway sluice gate, with RF device(RF)Gate, can activation group navigation automatically
System, and (X is inputted to vehicle0,Y0) coordinate initial value, when vehicle rolls highway sluice gate away from, with RF device(RF)Lock
Machine, group's navigation system can be closed automatically, and input (Xm, Yn) coordinate stop value to vehicle(See Fig. 9).
According to front and rear Z axis to(Over the ground)Dual-laser sensor(Blue shadow locating module)Can be to vehicle in certain period of time
The parameters such as lane change number of times, speed are implemented sampling and monitored.Vehicle axial line when front and rear Y-axis dual-laser sensor is used for installing

The random lane change of highway, "the" shape drive, continuous lane change, all can bring prestige to the traveling of itself and other vehicles
The side of body, imply that accident can occur at any time;
Although in addition, the brake system of modern vehicle all possesses anti-lock function, in order that preventing vehicle in skidding
Rollover and drift about, but for studying carefully its mode of braking, either pneumatic still to surge, either rear wheel drive or four-wheel drive,
Suffered brake force during each wheel brake, has dynamics and the difference of time, and what is then brought is the posture and row of vehicle
Enter the change of track;
When the vehicle run at high speed Yi Dan blowing out, drift about, it is out of control when, natural reaction often promotes driver reversely to hit
Steering wheel, causes vehicle with the bigger deviation angle(β), rush at hard shoulder, flank vehicle, drive in the wrong direction vehicle, or turn down overhead, lead to
Major accident.
When acute variation can all occur for the driving trace of vehicle, computer early warning system at this moment can be according to set by β value
Limit value scope, to nearby vehicle send accident warning, such as:Front vehicles are out of control, deceleration-avoidance-parking!(see figure
13)
Travel on a highway, the good driver of phychology, the driving trace mostly linear or smoothed curve of its vehicle
Shape system just can pass through speed(V), unit interval (Δ t), the deviation angle(β), deviation value(ΔX), occurrence frequency, deviation oscillation etc.
Parameter, is recognized and is monitored, and given a warning to violation vehicle:You are continuous in a short time(Frequently)Lane change, system will
Upload this act of violating regulations!
2nd, distance measuring sensor, tachogenerator
Rasterizing positioning method of the present invention, dependent on vehicle-mounted distance measuring sensor, tachogenerator to left and right vehicle wheel and front and rear essence

Just progressively it is being applied to the product for civilian use(See Fig. 7).
3rd, navigation map
Present navigation instrument mostly uses image electronic map, and such as satellite is taken photo by plane, aircraft is taken photo by plane, unmanned plane, vehicle-mounted panoramic
Clap etc.(See Fig. 8, Figure 18), not only highway image resolution ratio therein is restricted, and optical image is shot
The influences such as angle, sunlight projection, plate splicing, grade separation covering, quality is not high(See that broken circle is marked in Figure 18), it is difficult to realize essence
Quasi- navigation.
The present invention uses original highway CAD and builds design drawing, and it brings in the absence of above-mentioned image electronic map
Technological deficiency, even run into the covering building such as tunnel, grade separation, bridge, culvert, can also accomplish accurately to show and precisely lead
Boat.
4th, road early warning
When highway runs into the reasons such as burst accident, diastrous weather, highway maintenance and maintenance, implement interim close to road
When the measure such as closing, change its course, traditional means are a large amount of human and material resources of configuration, and upper road dredge unimpeded, or with station broadcast,
Road electronic display board informs that often effect is not good(Such as dense fog, sleety weather)And information delay, vehicle-mounted group's navigation system just may be used
This problem is solved easily, will be by the section vehicle as long as inputting relevant information on road administration detection common platform
Warning can be closed on vehicle-carrying display screen by flickering display at once, while voice message:The left-hand lane construction of 1000 meters of front is closed, note
Meaning alert flag!Slow down!Change its course traveling!Ensure that driving vehicle and construction operation personnel safely (see Figure 19).
Equally, for not driving into section personnel by mobile phone or system queries road conditions, it can learn that the section is closed in advance
Information is closed, so as to avoid the generation of congestion in road phenomenon.
