In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with attached drawing and example, to this
Invention is further elaborated.
Asset positioning system system of the present invention composition frame diagram is shown in Fig. 1, whole system Nei You data centers, base station,
Mobile PDA, platform user, movement/unicom launching tower, GNSS satellite, CORS1 and CORS2, wherein data center and each base station
Using optical fiber/ADSL connections, platform user and movement/unicom launching tower by network connection to data center, CORS1 and
CORS2 and data are communicated centrally through real-time performance data.Sampling instruments of the PDA as highway foundation data, using the Big Dipper+
The integrated navigation of GPS+GIONASS multisystems, positioning, time service, and combine CORS (a kind of satellite positioning tech, computer network skill
The product that the multi-party bit depth of a variety of new and high technologies such as art, digital communication combines) technology, GIS (GIS-Geographic Information System) technology, calculating
Machine, which models, and the technologies such as application are connected by wireless network with data center realizes data exchange.This system has positioning accuracy high
(up to Centimeter Level), high dynamic, it is anti-interference the features such as.
High-precision data collecting system ensure that the accuracy of the asset data spatial position of acquisition, in conjunction with visually
Figure, user are easy for that the physical location of corresponding assets can be found by assets latitude and longitude coordinates.But consider highway administration list
When carrying out data exchange between position, general pass course title, road width (uplink and downlink), pile No. describe the actual bit of specific asset
It sets.Therefore, a set of fine granularity, accurately and reliably space coordinate and pile No. correspondence are established, is the pass of the assets positioning system
Key.The assets positioning system gathered data automatically generates pile No. flow chart and sees Fig. 2, described in detail below：
1. road network latitude and longitude coordinates acquire
Road network acquisition, which is divided into, is actually embedded with kilometer stone section (such as highway, state's provincial highway, County Roads), in not being embedded with actually
The section (Ru Cundao) of journey stake only needs setting time interval to acquire section space bit for not being embedded with the section of kilometer stake actually
Coordinate information is set, for being actually embedded with the section of kilometer stake, except being adopted to section spatial positional information by setting time interval
Collection, it is also necessary to acquire the location information of each whole kilometer stake.
2. generating road network by stake point pile No.
For being actually embedded with the section of kilometer stone, need to consider pile No. indicated by kilometer stone with according to high-precision GPS
Relationship between the actual range that data are calculated.Such as：It is 1100 meters when certain section calculates distance, and practical pile No. is designated as
At 1000 meters, section should be compressed in proportion, and each meter of latitude and longitude coordinates are calculated in conjunction with azimuth.
The calculation formula of distance is solved according to 2 latitude and longitude coordinates that the time of setting acquires according to hand-held PDA：
Wherein haversin function expressions are haversin (θ)=sin2(θ/2)=(1-cos (θ))/2
R is earth radius, can be averaged 6371km；φ 1, φ 2 indicates the latitude of beginning and end；Δ λ indicates starting point
With the difference of terminal longitude.
According to the latitude and longitude coordinates of starting point, to by stake point 1 distance and azimuthal angle calculation by stake point 1 latitude and longitude coordinates：
First by the longitude and latitude (φ of starting point0,λ0) the projection seat calculated under Gauss plane coordinate system of just being calculated using Gauss
Mark (X0,Y0)。(X0,Y0)=GK (φ0,λ0), GK () represents Gaüss-Krüger projection.Wherein Gauss is just at last by geodetic coordinates
Gauss plane coordinate is solved, Gaüss-Krüger projection is the one kind in earth ellipsoid face and interplanar orthomorphic, in the present embodiment
For latitude and longitude coordinates are converted into plane orthomorphic coordinate.
Then according to starting point and the first distance S and azimuth alpha by stake point, calculate first coordinate
(X1, Y1), wherein X1=X0+ S*cos (alpha), Y1=Y0+S*sin(alpha).Finally utilize Gauss inverse (L1,B1)=GK-1(X1,Y1) first longitude and latitude (φ by stake point can be calculated1,λ1).Wherein Gauss inverse refers to by Gauss plane coordinate
Solve geodetic coordinates.Wherein S takes 1.1 meters.
Calculate successively second by stake point, third by stake point until the 999th latitude and longitude coordinates by stake point.
3. creating enclosure rectangle for coordinate of pile by pile tables of data generates pile No.
The coordinate of pile by pile data of generation, mainly provide basic data branch for assets acquisition system and other operation systems
Support,
For realizing conversion of the spatial data to pile No. data, if not being by one matched model of stake data creation
It encloses, system can not will almost get pile No. information.According to the catercorner length range of the enclosure rectangle of setting, coordinate of pile by pile is given
Data creation enclosure rectangle, enclosure rectangle frame number one pile No. of association, data center's clothes are stored in by the pile No. of generation
It is engaged in device, builds the coordinate of pile by pile database with query context.
4. the storage of gathered data
In view of the working characteristics of highway industry, when commencing business work, stability, accuracy, the ease for use of system
No doubt important, system when the network information is bad can normal use, the numerous hazardous environment of vehicle can first select fill out it is main
Complementary properties information is all problem needed to be considered after information.The Asset acquisition system has fully considered factors above, can
The logon data center under WIFI environment, when assets acquire, user need to only take pictures to assets at the scene, space coordinate
And pile No. information is obtained automatically by system, other information can be submitted after mobile phone terminal or the ends Web improve.
The asset data of acquisition can be shown by WebGIS in the form of map special layer, and clicking assets icon can
Check the details of assets.
5. the acquisition of assets pile No.
Assets pile No. obtains schematic diagram and sees Fig. 3.Scale represents the pile No. position by stake point in Fig. 3, and quadrangle represents each
By the rectangular envelope region of stake point.Highway business processing personnel hold mobile PDA positioning assets position when carrying out business processing
Set, two as shown in Fig. 3 assets 1 and assets 2 at assets.It searches assets to fall in which rectangle frame, take nearest apart from the assets
The associated pile No. of rectangle frame is the pile No. of the assets.Assets 1 are located at No. 2 by stake point enclosure rectangle, and the position of assets 1 is defined
At No. 2 stakes.The position of assets 2 is nearest by stake point enclosure rectangle from No. 4, and the position of assets 2 is defined as at No. 4 stakes.Through surveying
Examination, pile No. information and the nominal pile No. error of practical kilometer stone of the asset data of acquisition can be controlled within 1 meter, fully meet
Real work demand and industry data, which exchange, to be required.
The embodiment of the present invention is described with above attached drawing, but the invention is not limited in above-mentioned specific
Embodiment, the above mentioned embodiment is only schematical, rather than restrictive, those skilled in the art
Under the inspiration of the present invention, without breaking away from the scope protected by the purposes and claims of the present invention, it can also make several
Improvement and deformation, all of these belong to the protection of the present invention.
