Background
At present, the visualization that the urban water supply pipe network Geographic Information System (Geographic Information System-GIS) is matched with a map is mainly embodied in that the urban distribution display is combined with the water supply pipe network System, and the visualization has a macroscopic layout significance. Instantaneous pressure and elevation of a pipe network monitoring point are collected and uploaded to a cloud server, and the instantaneous pressure and elevation are displayed in a pipe network system in a point mode. There is no relation between the detection points to follow due to distribution and distance. The whole pipe network system is embedded between the small streets and the small lanes of the urban streets and the building districts, and has no change and distribution information of the pressure change of the pipe network, the hydraulic slope line, the pressure and the flow at the beginning end of the pipe network and the tail end of the pipe network (the inlet of the secondary water supply pump station) except the geographical position information. Therefore, the method is not beneficial to the development of the work of monitoring, adjusting and managing the operation of the pipe network, diagnosing faults, optimizing the operation and the like.
According to the existing GIS system, as no correlation is established between the pipe network data, in order to realize the integration of the structure and the function of the water supply pipe network (the change of the state of the pipe network is represented by detecting the parameters such as the pressure, the instantaneous flow, the position elevation and the like in any position pipeline in the pipe network), huge capital investment and labor cost are required to arrange monitoring points with higher density. The distribution density of the monitoring points of the pipe network directly depends on the cost, so the installation feasibility of the scheme is limited.
Moreover, at present, the visualization that the pipe network structure and the urban geographic information are matched with the map mainly highlights the distribution state of the pipe network in the city, but is not considered from the perspective of pipe network structure and function visualization.

Detailed Description
The following describes embodiments of the present invention in detail, which are developed based on the technical solutions of the present invention, and give detailed implementation manners and specific operation procedures to further explain the technical solutions of the present invention.
Example 1
The existing informatization pipe network system can not meet the requirements of pipe network operation monitoring, regulation management, fault diagnosis and operation optimization visually. The pipe network structure does not have functions, monitoring data are only displayed in a mode of marking the position of a detection point, and the monitoring data are not effectively integrated in the pipe network structure.
The present embodiment provides a method for visualizing a structure and a function of an urban water supply pipe network, as shown in fig. 1, the method mainly includes: the method comprises the steps of constructing a pipe network structure diagram, constructing an abstract pipe network structure diagram, constructing a pipe network structure map, constructing a pipe network structure function diagram, and displaying the abstract pipe network structure diagram, the pipe network structure map or the pipe network structure function diagram according to user selection.
1. Construction of a pipe network structure diagram
The pipe network structure is formed by combining pipe diameter, pipe length, bifurcation, intersection, valves (valve wells) and pipe network design parameters, so that a pipe network structure diagram is constructed, namely a pipe network structure frame constructed by geographical position, elevation, pipe diameter, nodes, turning points, intersection points and detection point data is constructed according to pipe network design data and pipe network GIS information. As shown in the operation flow of fig. 2, the preparation work is to create a table (for example, an Excel format) based on the identity of the pipeline (including the pipeline length, the node, the elbow, the cross pipe, the valve, etc.) through the pipeline design and laying drawing. Wherein the pipes arranged according to identity comprise the following information: pipe UID, pipe length (node, turning point and cross point), pipe diameter, starting point longitude and latitude and end point longitude and latitude. And then, importing the table into a system program to carry out pipe network structure recombination, wherein the method can be understood as splicing the pipelines according to the longitude and latitude to obtain a pipe network structure diagram.
2. Constructing abstract pipe network structure diagram
The pipe network structure diagram is reduced into an abstract pipe network structure diagram through abstract model mapping, and the abstract pipe network structure diagram is similar to an urban rail transit line diagram and comprises a starting point of a pipe network, a part of preset pipe network end points, and pipelines and valve wells (including valve wells with installed detection points and valve wells without installed detection points) from the starting point of the pipe network to the starting point of the pipe network, so that a user can select and display the pipe network structure diagram, and the relationship between the running state of an urban water supply network and the data of each detection point in the pipe network is conveniently established.
The abstract pipe network structure diagram shown in fig. 5, wherein: firstly, a pipe network starting point generally refers to an output end of a main pipe of a city power supply and pumping station; the pipe network pipeline has structural and functional representation; the pipe network end detection point generally refers to an inlet of a secondary water supply pump station; the positions of the pipe network valve wells generally represent the positions of pipe network nodes, inflection points and detection points; fifthly, the required (not installed) detection points are positioned at the position of the pipe network valve well. Sixthly, installing detection points at the positions of the pipe network valve wells, and integrating detection data into the information pipe network system.
3. Construction of pipe network structure map
Because the longitude and latitude information of the pipe network structure is obtained by design and installation, the initial pipe network structure diagram obtained by splicing is different from the urban digital map represented by the longitude and latitude positions of the urban map, and the initial pipe network structure diagram and the urban digital map have the difference of pixel point size (definition), dislocation (position deviation) and orientation (direction). If the after-recombination coincidence and the data processing are to be realized, the initial pipe network structure diagram and the urban digital map need to be aligned (Image Mapping), so that the pipe network structure map is aligned after the recombination of the pipe network structure, and the Image processing display operation such as Image integration, mutual conversion and the like can be carried out on the obtained pipe network structure map.
The alignment process may use a non-linear geometric transformation, or a non-linear three-dimensional difference (Tri-cubic Interpolation). Where "non-linearity" is the generation of a difference function by fitting a quadratic curve regression to the terrain. The relationship between the pipe network structure and the urban map image matching and converting can be established through nonlinear geometric transformation. After the pipe network structure (pipe) is matched with the city map image, any point (such as a vertex or a terminal point) of the pipe can find 4 corresponding adjacent points in the city map image (assuming that the pixel points of the pipe network structure and the map are 100% matched or have 0 probability in one-to-one correspondence). For example, fig. 3 and 4 depict a conversion relationship between a point on the pipeline (e.g., the end point) and 4 neighboring pixels on the map.
Fig. 3 shows a coordinate transformation relationship of pixel points after imaging in two different coordinate systems, where: representing a pipe network structure chart of a pipe network structure recombined according to the installation longitude and latitude, wherein each pixel point is represented by a (mu, v) coordinate system; representing an urban map image, and representing each pixel point by using an (x, y) coordinate system; thirdly, mapping the image pixel points (mu, v) of the pipe network structure diagram to 4 adjacent corresponding pixel points after the map (longitude and latitude) space; and fourthly, converting the relation from the (mu, v) to the (x, y) coordinate system.
Fig. 4 shows a non-linear three-dimensional difference method diagram. According to fig. 3, the transformation from (μ, v) to (x, y) coordinate system requires not only plane geometry difference parameters but also actual terrain variations. Combining the above two factors, the present embodiment refers to a nonlinear three-dimensional difference law. The nonlinear three-dimensional difference method is mainly characterized in that the number of adjacent and adjacent pixel points around the extension is expanded, a quadratic curve fitting of composite terrain change is adopted to generate a difference function, and difference weight is calculated according to the difference function, so that the optimal fit conversion relation is achieved.
4. Building pipe network structure function diagram
The method mainly realizes the function of the pipe network structure by simulating the pipe resistance assignment of the pipe through a Non-linear Regression Fitting function according to the pipe network structure.
The pipe network structure carries out data acquisition and comprises: the method comprises the steps of firstly, distributing pipelines (pipe diameter, pipe length, valve nodes, bent pipes and cross points), secondly, starting points (corresponding to) pressure, flow and elevation of a main pipe, thirdly, finishing points (secondary water supply pump stations distributed in a plurality of directions and positions) pressure, flow and elevation, and fourthly, distributing the pressure and elevation read at a pipe network monitoring point.
For a round tube pipeline, as shown in fig. 7, the calculation method for the pressure drop along with the length of the pipeline is as follows:
wherein, Deltapp represents the pressure drop change (Pa) relative to the starting point in the pipe, L is the distance from any point of the pipe to the starting point, Lambda is the friction coefficient of the pipe (lookup table), L represents the length of the pipe (m), D represents the diameter of the pipe (m), and rho represents the density of the fluid (water) (1000, kg/m)3) And upsilon represents the gravity flow velocity (m/s) of water, upsilon0Represents the inlet velocity (m/s) of the water pipe, k represents the conversion coefficient (lookup table, 0.849), C represents the roughness coefficient in the pipe (lookup table, cast iron pipe is 1.0, cement pipe is 1.1, steel pipe is 1.2 …), R represents the hydraulic radius (m)
S represents the slope (height difference between the beginning and end of the pipe divided by the length of the pipe,
)，Q0represents the pipe inlet flow (m)3In/s), A represents the cross-sectional area of the inlet of the pipe (m)2)。
The pressure drop functional relation of the arbitrary point of the pipeline relative to the starting point of the pipeline can be obtained by the calculation formula, and the short-hand writing is that Deltap is f (L, D, H, Q)0L) and l is the distance from any point of the pipeline to the starting point. Then, the pressure change of any point of the pipeline can be calculated and generated by collecting the water flow pressure, flow and elevation of the starting point and the ending point of the pipeline and based on the pressure drop function relation of any point of the pipeline relative to the starting point of the pipeline, and the pipeline can be randomly connectedAnd mapping the pressure change value of the point into a pipe network structure map through colors to obtain a pipe network structure function map. As shown in fig. 5, the color of the pipe network evolves from the starting point to the end in a gradient manner along with the flow pressure distribution, and the change of the pressure and the flow of the pipe network is reflected in real time, so that the monitoring and management requirements are met.
Because the distribution of the pipe network has the characteristics of complex bifurcation of the same-diameter pipes, crossed layout, insufficient number of detection points and the like, the calculation of the resistance of the pipes and the establishment of the relation between the pipe networks are inaccurate, and the coincidence degree of the pipe networks along the line and the map cannot achieve effective monitoring management. Therefore, in a more preferred embodiment, data accumulation is used, the change of the detected data at the beginning and the end is utilized, the existing data (or the real-time and historical collected data) is analyzed, and the unknown point pressure drop obtained according to the calculation formula is compensated, so that more accurate pressure drop data is obtained. And recombining an abstract pipe network structure function point distribution diagram similar to the abstract pipe network structure function point distribution diagram shown in the figure 5, and accurately marking all collection point data, including the pressure and the flow of a main pipe of a starting point of a water supply pump station and the pressure and the flow of an inlet of a secondary water supply pump station at the tail end of the pipe network, which are distributed at pressure and elevation detection points of the pipe network.
5. According to the selection of the user, displaying an abstract pipe network structure chart, a pipe network structure map or a pipe network structure function chart
After the abstract pipe network structure diagram, the pipe network structure map and the pipe network structure function diagram are obtained through construction, the corresponding diagrams can be displayed according to the optional selection of a user.
If the current display is the abstract pipe network structure diagram, the embodiment may further receive that a user selects an ROI in the abstract pipe network structure diagram, and perform a local enlarged display on the ROI of the pipe network structure diagram, and/or perform a local enlarged display on the ROI of the pipe network structure map, and/or perform a local enlarged display on the ROI of the pipe network structure function diagram.
Specifically, the user can select a rectangle composed of 4 vertices as the ROI area by dragging the frame in the abstract pipe network structure diagram, and the 4 vertices find corresponding points in the pipe network structure diagram, the pipe network structure map, and the pipe network structure function diagram to form a corresponding rectangle, and guide the local image in the rectangle into a new display space for enlarged display.
As shown in fig. 6, firstly, an abstract pipe network structure diagram is shown, and the operation state of a monitoring point is taken as a display key point, so that a supervisor can conveniently know the operation state of the pipe network and analyze the problem; selecting an ROI area in the abstract pipe network structure diagram by a user; thirdly, a local map belonging to the ROI area II in the pipe network structure map is obtained; fourthly, a local graph belonging to the ROI in the functional graph of the pipe network structure; the ROI is selected by a user in the pipe network structure function diagram; sixthly, corresponding three-dimensional figure of ROI area.
