Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pipeline facility drawing display apparatus that converts pipeline facility drawings such as water and gas into digital information and manages them.
[0002]
[Prior art]
In recent years, it has been proposed that digital pipe information and management of water supply pipes and water supply pipes are managed and already put into practical use. In order to manage the pipeline facility drawings as digital information, a large number of pipeline facility drawings stored hierarchically in a file device are displayed on a display device. In addition, correction work is also displayed on the display device. This is described in, for example, Japanese Patent No. 2656489.
[0003]
By the way, in a pipeline facility, it is necessary to perform pipeline network calculation to perform pipeline management, water pressure management by quantitative analysis of pipeline network characteristics, demand distribution trends, pipeline planning support, and the like.
[0004]
Conventionally, pipe network calculation is performed using pipe network drawings composed of water distribution pipes that connect nodes and nodes for pipe network calculation separately from pipe facility drawings (pipe drawings) described on the map of distribution pipes, etc. Is going. The pipe network calculation results are displayed in a simplified pipe network drawing.
[0005]
Pipe network drawing information (data) of the pipe network drawing is described in the form of the connection point (node) of the pipe and the pipe (branch) divided there. The pipeline drawing information of the pipeline facility drawing includes attribute information such as the pipeline diameter and construction year.
[0006]
[Problems to be solved by the invention]
The pipe network drawing is only described in the form of connection points (nodes) of pipes and pipes (branches) divided there. For this reason, when the pipe drawing is used for construction work, it is a heavy burden on the construction personnel who cannot easily understand the correspondence between the pipe drawing and the pipe network drawing.
[0007]
The present invention has been made in response to the above-described points, and an object of the present invention is to provide a display device for a pipeline facility drawing that allows a pipeline network calculation result to be easily grasped by the pipeline drawing.
[0008]
[Means for Solving the Problems]
A feature of the present invention is that pipe network drawing information having node information for performing pipe network calculation using the pipe drawing information is created and stored in association with the pipe drawing information. The pipe network calculation result obtained from the drawing information is displayed on the display device simultaneously with the pipe drawing information.
[0009]
According to the present invention, it is possible to easily grasp the relationship between pipes and piping systems of pipe line equipment and pipe network calculation results, so that the burden on construction personnel can be significantly reduced.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments according to the present invention will be described below in detail with reference to the drawings.
[0011]
FIG. 1 shows an embodiment of the present invention.
[0012]
In FIG. 1, the central processing unit 1 includes a data management unit 10, a pipe network analysis / display control unit 20, and files 30, 40, 50, 60, 70, 80, 90, 100 for storing various data. .
[0013]
The data management unit 10 includes a meter reading information input unit 110, a water supply / distribution drawing (pipeline facility drawing) input unit 120, and a pipe network calculation pipe diagram generation unit 130. The pipe network analysis / display control unit 20 includes , A pipe network calculation unit 210, a calculation result display unit 220, and a calculation result water distribution diagram superimposing display unit 230.
[0014]
First, as shown in FIG. 2, the meter reading information input unit 110 is input from a meter reading information storage medium 7 (for example, a magnetic tape) in which customer meter reading data is stored by the processing of “reading meter reading information” in step 1101. Obtained via the output device 6 (for example, a magnetic tape device).
[0015]
In the process of “store meter reading data” in step 1102, the acquired water meter number 701 and the used water amount 702, etc., which are customer meter reading data are stored in the meter reading data file 70, and the used water amount 812 of the customer attribute 81 in the attribute database 80 is stored. Is updated using the faucet number 811 as a key.
[0016]
The water supply / distribution drawing (facility drawing) input unit 120 inputs and corrects a water supply / distribution diagram (pipe drawing) based on operation signals input from input devices such as the mouse 2, the keyboard 3, and the tablet device 5. For example, as shown in FIG. 3, input and correction of water supply pipes, water distribution pipes, and various water supply facilities are executed on the water supply / distribution diagram 310 by the processing of “input water supply / distribution drawing” in step 1201.
[0017]
In the “facility attribute input” process at step 1202, various attribute information including customer attribute information 81 and pipeline attribute information 83 stored in the facility attribute database 80 is input. The figure of the house 3101 is designated with the mouse 2, and the faucet number 811 or the like is entered from the attribute input screen displayed on the display device 4.
[0018]
In step 1201, whether or not “drawing input has been completed” is determined in step 1203. If not completed, the processing in steps 1201 and 1202 is repeatedly executed. If it is determined in step 1203 that drawing input has been completed, it is stored in the water supply / distribution diagram file 30 and also in the facility attribute database 80 by the “input information storage” process in step 1204.
[0019]
FIG. 4 shows a database structure example of customer attribute information 81 and pipe attribute information 83 in the facility attribute database 80 .
[0020]
As customer attribute information 81, faucet number 811, water consumption 812, meter reading section 813, user number 814, user name 815, user address 816, device location 817, opening / closing section 818, opening / closing date 819, meter diameter 820 etc. are stored.
[0021]
The pipeline attribute information 83 includes drawing number 831, construction number 832, pipe classification 833, construction year 834, pipe type 835, caliber (mm) 836, extension 837, acquisition date 838, acquisition price 839, useful life The number of years 840, the removal date 841, etc. are stored.
[0022]
FIG. 5 is a conceptual diagram that is generated from the water distribution diagram (pipe diagram) 310 of the pipe network diagram 510 for calculating the pipe network.
[0023]
In the water supply / distribution diagram 310, various water supply facilities such as a water distribution pipe 3103 indicated by a solid line, a water supply pipe 3104 indicated by a broken line, a customer 3101 and a gate valve 3102 are input.
[0024]
In order to create a pipe network diagram of all the water supply and distribution pipes from the water supply and distribution chart 310, a connection point information file 40 is created that treats the end points and intersections of each pipe line and the water facility installation location as connection points 3105, 3106, and the like.
[0025]
Pipe network calculation pipe network diagram 510 shows water pipe 3107 connected to water pipe 3103 and node 5105 corresponding to connection point 3105 generated from the end points of water pipe 3108 when viewed with respect to water pipe 3103 in water supply and distribution diagram 310. Thus, the distribution pipe 3103 is divided into distribution pipes 5103 and 5109. In addition, the pipe network calculation pipe network diagram 510 includes pipe line facilities such as nodes 5106, water distribution pipes 5107 and 5108, and a gate valve 5102.
[0026]
It will be described with reference to FIG. 6 whether it is necessary to create the pipe network diagram 510 from the water supply / distribution diagram 310 in this way.
[0027]
As shown in the input correction example of the water supply / distribution diagram 310 in FIG. 6A, there is a pipe D100 having a caliber 100 sandwiched by a pipe D200 having a caliber 200, and the pipe D100 is the same in two places in the middle. Suppose that it is branched by a pipeline with a caliber. In addition, it is assumed that the diameter changing point 3109 is input to the connection point between the pipe lines D200 and D100.
[0028]
Considering the case where the pipe D100 sandwiched by the diameter change point 3109 is changed to D150 in the normal waterworks construction (portion enclosed by an ellipse in the figure), in the water distribution diagram 310, the pipe D100 is connected to the pipe D150. It can be done with a book.
[0029]
However, in the pipe network diagram 510 for calculating the pipe network, as shown in FIG. 6 (b), data must always be constructed in the relationship between nodes and pipes.
[0030]
In the pipe network diagram 510 of FIG. 6 (b), the node 5110 and the four nodes on the left side of the pipeline always occur at the intersection of the pipes. No longer.
Thus, when the pipe drawing handled by construction and the pipe drawing handled by pipe network calculation are different, drawing data management becomes complicated, and erroneous input or correct pipe network calculation results may not be obtained.
[0031]
In the present invention, a normally used water supply / distribution diagram (pipeline facility drawing) is maintained and managed so that execution of the pipe network calculation and the result of the pipe network calculation can be displayed simultaneously with the pipe drawing.
[0032]
FIG. 7 shows an operation explanatory diagram of the pipe network calculation generation unit 130 for calculating the pipe network based on such a concept.
[0033]
First, the network diagram generation unit 130 performs the processing of Step 1301 “Create intersection point information by searching for intersections and facility symbols” in the water distribution diagram of the water distribution diagram file 30 and the pipe end points of the distribution pipes. Then, connection point information to be stored in the connection point information file 40 is created from the intersection of the pipe line and the water facility symbol.
[0034]
An example of the connection point information is shown in FIG.
[0035]
In FIG. 8, the connection point information is key information in which the X coordinate 402 and the Y coordinate 403 indicate the connection point position, and the number of figures connected to the corresponding point is stored in the element number 404. The pipe network calculation node / pipe line NO 401 stores the corresponding node NO or pipe line NO when the corresponding connection point is a node of the pipe network calculation pipe network or a point on the pipe line in the processing described later. This is for the correspondence between the figure in the figure and the pipe network calculation information. In this process, the initial value is set to 0 (zero).
[0036]
Each element information to be connected to the corresponding point includes drawing number 405 when the water supply / distribution chart is divided for each area, figure line 406, broken line end point (= 0), line middle (= 1), symbol (= 2) Stores the classification of etc.
[0037]
In addition, the drawing information is hierarchized and managed in layers, and is classified into three categories: a large layer classification 407, a middle layer classification 408, and a small layer classification 409.
[0038]
When the connecting element is a polygonal line figure, the constituent point number 410 stores which constituent point on the polygonal line the connecting point position is between. Furthermore, the figure reference number of the connection element figure is registered in the figure ID 411.
[0039]
Returning to FIG. 7, the construction of pipe network diagram information for pipe network calculation will be described for all supply and distribution pipes.
[0040]
First, it is determined in step 1302 “whether the relevant pipe line is a calculation target” whether or not the relevant water distribution pipe is used for pipe network calculation. Usually, in order to shorten the time required for calculation, determination is made based on the diameter value such as a diameter of 100 mm or more, but there is a possibility that a pipe line that does not connect to the supply source in the pipe network calculation may appear depending on the connection state of the water distribution pipe line. For this reason, pipelines for which “calculation required” is set in the calculation necessity / unnecessity 841 of the facility attribute database 80 are set as pipe network calculation targets regardless of the diameter value.
[0041]
In Step 1303 “Divide the relevant pipe graphic by connection point information and generate a node graphic at the dividing point”, a connection point record in which the relevant pipe figure is registered as an element for the pipe calculation target pipe is obtained. A search is made from the connection point information file 40, and a point where another pipe is connected to the intermediate point of the corresponding pipe is extracted from the layer large classification 407, the middle middle classification 408, and the small layer classification 409 of elements other than the corresponding pipe. The extracted points and the start and end points of the corresponding pipe are set as nodes and pipe dividing points.
[0042]
Based on this result, the pipe graphic is divided and registered as pipe information of the pipe network calculation file 50. At the same time, the node graphic is registered. At this time, if the node number has already been entered in the pipe network calculation node / channel NO 401 of the connection point record corresponding to the node, the node is not registered, and step 1305 “create node attribute for each node figure” described later. ”Is not executed. This is to prevent double registration when a plurality of pipelines are connected to one node.
[0043]
At this time, the pipeline NO1021 and the node NO1011 of the calculation facility attribute database 100 are determined at the same time, and the node NO is assigned to the pipeline calculation essential node / channel NO401 of the connection point record to be the node, and the corresponding pipeline other than the node is assigned. In the connection point record registered as an element, the pipeline NO is set as a negative value (to distinguish it from the node NO).
[0044]
Thereafter, in the process of Step 1304 “Create water distribution line attribute for each divisional line”, the water distribution line attribute 202 of the calculation facility attribute database 100 is created based on the facility attribute database 80. The node numbers of the pipeline end points are stored in the pipeline NO 1021 for managing each pipeline independently, the start node number 1022, and the end node number 1023.
[0045]
Further, the diameter 1024 of the corresponding pipe attribute 83 is stored in the diameter 1024 of the calculation facility attribute database 100, and the pipe attribute 83 is added to the extension 837 of the corresponding pipe attribute 83 in the extension 1025. Stores a value obtained by multiplying the total length of the target pipe graphic and the ratio of the graphic length from the start node to the end node of the graphic corresponding to the distribution pipe attribute 102 to be set.
[0046]
Further, a C value (initial value is a default value, for example, 110), which is a pipe resistance value, is stored in the pipe resistance coefficient 1028 and used as a calculation condition for calculating the pipe network.
[0047]
Next, in step 1305 “Create node attribute corresponding to each node graphic”, the node NO 1011 is set in the node attribute 101, and the altitude 1012 is stored in the altitude data file 100. Thus, the altitude at each node is obtained and set to altitude 2012. The set altitude can be individually modified by modifying the attributes as necessary. Also, an initial value 0 is set for the allocated demand amount 2013.
[0048]
The processing of the above steps 1301 to 1305 is performed on the all water supply and distribution pipeline graphic, and if it is determined in step 1306 that “all water distribution pipelines have been processed”, the process proceeds to step 1307.
[0049]
In step 1307 “Isolated pipeline check”, an error is extracted from an isolated pipeline having no connection route from the supply source to the generated pipeline calculation pipeline data. In the unlikely event that there is an isolated pipeline, there will be a problem such as the pipe network calculation not converging. Therefore, the surroundings of the pipeline that caused the error in step 1307 are reviewed, and the calculation necessity in the pipeline attribute 83 of the facility attribute database 80 is determined. After making 841 “necessary of calculation”, etc., the pipe network calculation pipe diagram generation unit 130 of FIG. 1 is operated again and repeatedly executed until there is no error.
[0050]
In the “conversion of facilities on pipes such as valves” processing in step 1308, the supply source such as a reservoir, which is a pipe network calculation target element other than the pipes, and the valves and pump facilities on the pipes are converted. For all target figures such as valves, a record in which the corresponding element is stored in the connection point information file 40 is searched, and the pipe number is stored in the pipe network calculation node / line NO401 of the corresponding record. Only the corresponding facility graphic and attribute data are stored in the pipe network calculation pipe diagram file 50, and the corresponding pipeline NO is added and stored in the calculation facility database 100. In addition, it is also possible for these figures and attribute data to share the information of the water supply and distribution diagram 30 and the facility attribute database 80.
[0051]
Finally, the demand allocation which is one of the pipe network calculation execution conditions is performed on the nodes of the created distribution pipe network diagram by the processing of Step 1309 “Calculation of demand allocation to each node”.
[0052]
The processing of “demand allocation calculation for each node” in step 1309 is performed as shown in FIG.
[0053]
In FIG. 10, by the process of “determining customer coordinates” in step 13091, the graphic (x, X) corresponding to the customer attribute is obtained from the customer attribute 81 of the facility attribute database 80 and the water supply / distribution drawing of the water supply / distribution diagram file 30. y) Find the coordinates.
[0054]
The distribution pipe network is obtained from the (x, y) coordinates of the consumer obtained in step 13091 and the connection point information of the connection point information file 40 by the processing of “search from the customer to the nearest node on the distribution network” in step 13092. Among the nodes on the diagram, the node closest to the customer is searched.
[0055]
The process proceeds from the step 13092 to the process of “set the customer usage water amount to the node attribute of the nearest node-assigned demand amount” in the step 13093, and the use of the customer stored in the customer attribute 81 of the facility attribute database 80 is used. The amount of water 812 is added to the allocated demand amount 1013 of the node attribute 101.
[0056]
As described above, the demand allocation process is repeatedly executed for all customers based on the determination of “execute all customers” in step 13094.
FIG. 9 shows a conceptual diagram of a pipe network diagram for pipe network calculation.
[0057]
FIG. 9 shows a state where the water supply / distribution drawing is converted into a pipe network calculation pipe network. The pipe network calculation pipe network diagram has a data structure in the form of nodes and pipes necessary for pipe network calculation. I understand that.
[0058]
In the figure, reference numerals 3106 and 5104 denote supply points such as distribution reservoirs.
[0059]
The pipe network calculation unit 210 performs the pipe network calculation using the pipe network calculation pipe diagram 510 and the calculation facility attribute database 100 created as described above, and the calculation result is stored in the calculation result file 60. .
[0060]
The calculation result display unit 220 supplies calculation results such as pressure distribution and flow distribution to the display display device 4 using the pipe network diagram data stored in the calculation result file 60 and the pipe network calculation pipe network file 50. Displayed simultaneously with the distribution pipe diagram, that is, superimposed.
[0061]
Moreover, the calculation result water supply / distribution diagram superimposing display section 230 displays the water / distribution diagram stored in the water / distribution diagram file 30 on the display device 4 by enlarging the display drawing to a certain level or more as shown in FIG. After that, from the customer 3101 indicated by the mouse in the water supply / distribution map, the connection destination pipeline is sequentially searched using the water supply / distribution graphic information and the connection point information file 50, and the nearest node on the water distribution network diagram is obtained. The corresponding calculation result is retrieved from the calculation result file 60.
The estimated pressure at the customer 3101 is obtained using the route pipeline information (caliber, pipeline length) and elevation information from the customer to the node obtained in the search process, and the pressure on the water distribution map is obtained. Display the value.
[0062]
At this time, by providing the number of floors (height) of the building in the customer attribute 81 stored in the facility attribute database 80 , it is possible to obtain the estimated water supply pressure on the top floor in a two-storied or higher house, Judgment of directly connected water supply becomes possible.
[0063]
In this way, the pipe network calculation result is displayed on the display device at the same time as the pipe drawing information, but the pipe network drawing information having node information for performing pipe network calculation using the pipe drawing information is shown in the pipe drawing. It is created and stored in association with the information, and the pipe network calculation result obtained from the pipe network drawing information is displayed on the display device simultaneously with the pipe drawing information. Therefore, since the relationship between the pipeline and the pipeline system of the pipeline equipment and the pipeline network calculation result can be easily grasped, the burden on the construction personnel can be significantly reduced.
[0064]
