Embodiment

Specifically as shown in Figure 2, the present invention is as follows in the step that Google Maps and GIS pipe network figure report water supply network malicious event method for repairment:

Step 1: build the GIS pipe network service system that merges Google MapsAPI.

The API of the Google Maps API that the present invention the uses map programming that to be Google provide as the developer.It allows the developer in the situation of the map server that needn't set up oneself, the Google Maps data is embedded among the website, thereby realizes embedding Google's Map Services application, and be the user-provided location service by Google's coordinate system coordinate figure data.

GIS is Geographic Information System, is overall treatment and a kind of technological system of analyzing geographical spatial data, is to survey and draw to be measured as the basis, with the data source of database as data storing and use, and the instant technology of global space analysis take computer programming as platform.GIS pipe network service among the present invention is take the pipe network schema mapping as the basis,,, builds this GIS pipe network service and need to carry out following steps for the user provides the service of checking pipe network spatial information and attribute data as data source with the pipe network attribute data:

Step 1.1: call Google Maps API map localization method, navigate to the pipe network location at Google Maps.

Step 1.2: convert public supply mains schema mapping (it is the file of CAD form that existing most cities is built schema mapping) to GIS map document, i.e. mxd file by the ArcGIS application development software.

Step 1.3: on ArcGIS map visualization operation interface, the attribute information of typing pipe network.The ArcGIS application development software reaches " batch input " attribute information for the user provides " selecting regional typing ", has greatly reduced data typing personnel's workload.

Step 1.4: will be take the pipe network schema mapping as the basis, with the pipe network map of pipe network attribute data issue after the section is set, namely finish the construction of GIS pipe network service.

Above-mentioned GIS pipe network Service and Construction method does not need to make the urban geography map, has avoided the complicated processes of city map and pipe network figure stack.Therefore, Running-water Company only needs a small amount of workload, can reach traditional GIS pipe network geographical service and need expend the effect that a large amount of human and material resources just can reach, and embodying thus the present invention has huge economic benefit.

Step 2: city, the own place of Public choice, enter corresponding Google's electronic chart, choose the pipe network accidents origination point at map, and the simple accident description of typing, the accident of namely finishing reports work.

Step 3: accident is mapped on position corresponding to GIS pipe network figure through the coordinate direct transform.

The key that the present invention realizes is shown in Figure 1ly will to report the pipe network malicious event for repairment on Google Maps or the GIS pipe network figure, by coordinate conversion accident point is mapped on Google Maps and the GIS pipe network figure simultaneously.Because Google Maps and GIS pipe network schema mapping all are the linear scaling maps, can the upper accident point of Google Maps be shone upon on GIS pipe network schema mapping by the linear equation in two unknowns group, solving equation is as shown below:

$\left\{\begin{array}{c}{x}^{\′}=\left[\begin{array}{c}a\\ b\end{array}\right]\left(\begin{array}{cc}y& x\end{array}\right)\\ y^{\′}=\left[\begin{array}{c}c\\ d\end{array}\right]\left(\begin{array}{cc}y& x\end{array}\right)\end{array}\right.;$

Wherein, x, y represent that respectively accident point is at dimension and the longitude of Google Maps coordinate system; X ', y ' represent that respectively accident point is in precision and the dimension of GIS pipe network schema mapping coordinate system; A, b, c, d are that Google Map coordinate system is to the conversion coefficient of GIS pipe network schema mapping coordinate system conversion.

The method for solving of coordinate conversion coefficient is:

(1) on Google Maps coordinate system and GIS pipe network schema mapping coordinate system, looks for respectively two pairs of coordinate points that the position is relative, be designated as (x1y1), (x1'y1'), (x2y2), (x2'y2').

(2) solving equation group $\left\{\begin{array}{c}{x}_1^{\′}=\left[\begin{array}{c}a\\ b\end{array}\right]\left(\begin{array}{cc}{y}_1& x_1\end{array}\right)\\ x_2^{\′}=\begin{array}{c}\left[\begin{array}{c}a\\ b\end{array}\right]\end{array}\left(\begin{array}{cc}{y}_2& x_2\end{array}\right)\end{array}\right.$ With $\left\{\begin{array}{c}{y}_1^{\′}=\left[\begin{array}{c}c\\ d\end{array}\right]\left(\begin{array}{cc}{y}_1& x_1\end{array}\right)\\ y_2^{\′}=\begin{array}{c}\left[\begin{array}{c}c\\ d\end{array}\right]\end{array}\left(\begin{array}{cc}{y}_2& x_2\end{array}\right)\end{array}\right.$ Obtain a, b, c, d conversion coefficient value.

Step 4: after mapping was finished, the pipe network maintainer just can see the pipe network malicious event that newly reports at GIS pipe network figure.May there be the deviation of small distance in the actual position of reporting of user pipe network accidents point position and pipe network, this moment, the pipe network maintainer needed according to the geographic position that reports, it is online that respective tube is adjusted in the accident point position, can read attribute information and the binding of this section pipe network from the GIS database.

Step 5: if the known pipe network malicious event of pipe network maintainer then by the direct typing accident on GIS pipe network figure of maintainer, reads attribute information and the binding of this position pipe network from the GIS database.

Step 6: accident is mapped on position corresponding to Google Maps through coordinate inversion.

Accident point inverse mapping on the Google Maps coordinate system on the GIS pipe network schema mapping coordinate system, its inverse transformation solving equation is:

$\left\{\begin{array}{c}x=\left[\begin{array}{c}{a}^{\′}\\ b^{\′}\end{array}\right]\left(\begin{array}{cc}{y}^{\′}& x^{\′}\end{array}\right)\\ y=\left[\begin{array}{c}{a}^{\′}\\ b^{\′}\end{array}\right]\left(\begin{array}{cc}{y}^{\′}& x^{\′}\end{array}\right)\end{array}\right.;$

Wherein, x ', y ' represent that respectively accident point is in precision and the dimension of GIS pipe network schema mapping coordinate system; X, y represent that respectively accident point is at dimension and the longitude of Google Maps coordinate system; A ', b ', c ', d ' are that the GIS coordinate system is to the conversion coefficient of Google Maps coordinate system conversion.

The method for solving of coordinate conversion coefficient is identical with the method that coefficient is found the solution in direct transform.

By above-mentioned mapping method as can be known, the pipe network malicious event has only carried out the conversion of coordinate figure when Google Maps and GIS pipe network schema mapping shine upon, do not relate to the transmission of any pipe network property value.Fundamentally cut off thus the approach that the public connects GIS pipe network attribute database, greatly improved the secret and safe of pipe network data.

Step 7: the pipe network maintainer derives the form that comprises accident point Google geographic position and this pipe network attribute information, transfers to on-site maintenance personnel repairing.The on-site maintenance personnel had grasped whole geography information and pipe network attribute information before the accident of arriving is present like this, determined fast incident point position and prepared material, instrument according to the pipe network attribute information.

Fig. 3 reports pipe network malicious event method block diagram for repairment for the public.After the public enters system, select first the city, place, enter corresponding Google's electronic chart.On Google Maps, the public can see the pipe network malicious event that has reported for repairment, if the accident that need to report for repairment exists, and complete operation then.Otherwise will choose the pipe network accidents origination point at map, and the simple accident of typing describes, stay journalist's name and contact method, the accident of namely finishing reports work.The electronic chart that the present invention uses is the Google Maps that the public often uses, and simple, the easy row of accident report method, has reduced the public and has used the GIS Geographic Information System to report the service threshold of pipe network accidents.

Fig. 4 is pipe network maintainer affirmation accident, reports the accident method.For the known pipe network accidents of those maintainers, the pipe network maintainer can the maintainer direct typing accident on the corresponding pipe network section of GIS pipe network figure, attribute information and the binding that can from the GIS database, read this position pipe network; For the pipe network accidents that the public reports, the maintainer need to proofread and correct the accident point position at GIS pipe network figure, finishes thus attribute information and the binding of accident and pipe network.At last, the pipe network maintainer derives the form that comprises accident point Google geographic position and this pipe network attribute information, transfers to the on-site maintenance personnel and processes.The present invention is in conjunction with the advantage of Google Maps and GIS geographical service, and for the maintainer provides, more easily function services more directly perceived than traditional GIS pipe network geographical service, and its construction cost is far smaller than the development ﹠ construction of traditional GIS pipe network geographical service.

Fig. 5 is on-site maintenance personnel workflow diagrams.The on-site maintenance personnel can obtain this accident point Google geographic position and this pipe network attribute information before place to go director event, according to the Google Maps location, the maintenance personal can find accident point easily and fast; And the pipe network attribute information of having grasped, such as information such as tubing, caliber, buried depths, can assist the maintenance personal to prepare in advance material and instrument, improved work efficiency.
