Abstract

PURPOSE:To automatically avoid the overlap of numerical information without the alteration operation of an operator by altering a display position within a setting range when the overlap of the display position of plural pieces of numerical information displayed in a pipe network diagram is discriminated. CONSTITUTION:It often occurs that plural pieces of numerical information on a pipe line are overlapped, and numerical information on the pipe line is overlapped with numerical information on a node at a place constituted by the pipe line whose extension is short among numerical information arranged for the pipe network diagram. It is discriminated whether the overlapped part is present or not based on coordinate data (xi, yi). When the overlapped part is present, data on the pipe line is shifted right/left/upward/downward by set distance. Data on the node is shifted along circumference where a setting length is set to be a radius and the overlapped state is avoided. Pipe network information after the overlapped state is avoided is decided as output information, and it is outputted to a display unit such as CRT and an output unit such as a printer.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an analyzing means for performing fluid analysis on a fluid supply pipe network such as a water supply supply pipe network or a gas supply pipe network, and an analysis result obtained by the analyzing means. The present invention relates to a pipe network analysis apparatus having display processing means for displaying numerical values at predetermined locations on a pipe network diagram showing the arrangement of a network.

[0002]

2. Description of the Related Art In a pipe network analyzer of this type, numerical data such as pressure and flow velocity, which are the results of analysis by an analyzing means, are used to identify the corresponding pipe line in a pipe network diagram showing the arrangement of the fluid supply pipe network. A display processing means for displaying a numerical value is provided at a predetermined position near the node. The data that should be displayed as analysis results in the water supply network include basic data such as pipeline diameter and pipeline extension, flow velocity and flow rate data for pipelines, and ground height, head, and extraction for nodes. There were water amounts, etc., and all of them or several kinds of arbitrarily selected data were displayed. In addition, the display positions of the pipeline were the center position in the longitudinal direction of the pipeline and both sides of the pipeline, and the nodes were the upper right position of the node.

[0003]

However, according to the conventional display processing means, a plurality of numerical data on a plurality of conduits and nodes are uniformly arranged at predetermined positions. Depending on the target network diagram, multiple pieces of numerical information may overlap, and in such a case, it will be unsightly. Therefore, while the operator visually checks the pipe network diagram displayed on the display device such as a CRT and detects the overlapping portion, one of the numerical information which overlaps,
Alternatively, it is necessary to change both arrangements by using an input device such as a keyboard and a mouse. Since such a changing operation requires a great deal of attention for a long time, there is a drawback in that the operator's physical and mental burden is extremely large.

Therefore, it is conceivable to reduce the numerical information in the overlapping portion to avoid the overlapping, but there is the following inconvenience. That is, when displaying on a display device such as a CRT, the entire target network diagram may be displayed collectively or a part may be enlarged and displayed, all of which are managed as one sheet of drawing information. Therefore, when the numerical information is reduced and displayed, it becomes impossible to read the numerical information when the entire network diagram is displayed collectively. Therefore, it is impossible to reduce the size of the entire target network diagram to a size that can be read when it is displayed all at once.

An object of the present invention is to eliminate the above-mentioned conventional drawbacks, and it is possible to automatically avoid overlapping of a plurality of numerical information displayed on a network diagram without an operator's changing operation. The point is to provide a pipe network analysis device that can do this.

[0006]

In order to achieve this object, a characteristic configuration of a network analysis apparatus according to the present invention is that a display processing means is provided with an overlap of display positions of a plurality of numerical information to be displayed on a network diagram. The point is that a discriminating means for discriminating and a display position changing means for changing the display position within the set range when the overlap is discriminated are provided. In the above-mentioned configuration, if the overlapping of the display positions of the plurality of numerical information to be displayed on the network diagram is not resolved even by changing the display position by the display position changing means, the operator can identify the corresponding display position. It is preferable to provide warning display means. Furthermore, if the overlapping of the display positions of the plurality of numerical information to be displayed on the network diagram cannot be resolved even by changing the display position by the display position changing means, the part of the network diagram relating to the corresponding numerical information is displayed. It is preferable to provide a display mode changing means for displaying numerical values after enlarged display.

[0007]

The display processing means first displays numerical data such as pressure and flow velocity as the analysis result by the analyzing means for the corresponding pipeline or node in the pipeline network diagram showing the arrangement of the fluid supply pipeline on the memory. It is placed at a predetermined location in the vicinity. Next, the discriminating means determines whether or not the display positions of the numerical information are overlapped by displaying the address data of the numerical information display area on the memory (for example, assuming that the network diagram is represented on the XY plane, displaying each numerical information). (Corresponding to the xy coordinate data indicating the area), and when a plurality of numerical information arrangement areas overlap,
The display position is changed within the set range by the display position changing means to avoid the overlap, and then displayed on the display means.

In the above structure, if the overlapping of the display positions of the plurality of numerical information to be displayed on the network diagram is not resolved by the change of the display position by the display position changing means, the warning display means takes appropriate action. In order that the numerical information can be identified by the operator, for example, different display colors are displayed or blinking is displayed to call attention to the subsequent correspondence of the operator.

Further, when the overlapping of the display positions of the plurality of numerical information to be displayed on the network diagram cannot be solved by the change of the display position by the display position changing means, the corresponding numerical value is changed by the display mode changing means. The part of the network diagram relating to the information is enlarged and arranged in another area on the memory (a part of the display area of the network diagram, or a new area of the area), and the part of the enlarged network diagram is expanded. Numerical information is placed for.

[0010]

Therefore, according to the present invention, when the analysis result is displayed, the overlapping of a plurality of numerical information displayed on the network diagram is automatically avoided without a complicated change operation by the operator. As a result, it is possible to provide a pipe network analysis apparatus that does not cause an operator to be extremely tired and does not cause information loss or overlapping and unsightly appearance.

Further, in the case where the warning display means is provided, the operator only has to change the overlapping portion using an input device such as a keyboard and a mouse only for the portion where the warning is displayed. Will be greatly improved.

When the display mode changing means is provided, even if the display position changing means cannot avoid the overlap of the numerical information, the avoiding process can be surely performed without the manual operation by the operator. .

EXAMPLES Examples of the present invention will be described below. As shown in FIG. 6, a pipe network analysis device for a water supply facility includes a preprocessor unit 1 for generating analysis target data, a solver unit 2 for executing fluid analysis (hydraulic analysis) on the analysis target data, and an analysis result. And a post-processor section 3 for generating output data for displaying with high visibility.

Each of them is composed of a single computer or the same computer, and in the preprocessor unit 1, basic data such as extension data, diameter data, connection data, etc. of each pipe constituting the pipe network to be analyzed. , The ground height of the water source, the ground height of each node, the water amount data extracted from the node, etc. are generated as analysis target data, and the solver unit 2
Then, the nodal equation was solved for the data to be analyzed based on the pipeline characteristics that adopted the empirical formula of Hazen-Williams, and it was evaluated whether or not the amount of water supplied from the water source was sufficiently supplied at the terminal side. Therefore, the flow velocity, the flow rate data, etc. for the pipeline, the head, etc. for the nodes are derived, and the post processor unit 3 generates output data for displaying the above-mentioned analysis result with good visibility.

The processing in the post processor unit 3 will be described below with reference to the flowchart shown in FIG.
Numerical data that is the analysis result (flow rate, flow velocity, head, etc.) obtained by the solver unit 2 is arranged at a predetermined location of the analysis target pipe network drawing information obtained by the preprocessor unit 1.
More specifically, as shown in FIG. 2, with respect to the pipeline network diagram developed in the internal memory of the computer, as for pipelines, basic data such as pipeline diameter and pipeline extension, flow velocity, flow rate data, etc. For nodes, up to three types of data selected arbitrarily from data such as ground height, water head, amount of water taken out, etc. can be selected. For pipelines, the central position in the longitudinal direction of the pipeline Regarding the nodes on both sides, they are arranged at the upper right position of the node <# 1>. Here, as shown in FIG. 3, each numerical information is arranged in a set font in a square display area of a set size, and the coordinate data (x _i , y _j of the corner of the square is set. ) Is associated with the address data of the internal memory (mapping memory) in which the network diagram information is stored.

As shown in FIG. 4, among the numerical information arranged on the network diagram, the numerical information about the pipelines and the numerical information about the pipelines are included in the portion constituted by the pipelines having a short extension. Numerical information about nodes may overlap.
Whether or not there is such an overlapping portion is determined based on the above-mentioned coordinate data (x _i , y _j ) <# 2>, and when there is an overlapping portion, as shown in FIG. For the data about the pipeline, move it up and down left and right by the set distance,
The data relating to the node is moved along the circumference having the set length as the radius to avoid the overlapping state as shown in FIG. 5 <# 3>.

In this way, the network diagram information after avoiding the overlapping state is determined as output information and output to a display device such as a CRT or an output device such as a printer <# 6>.
When the operator enlarges and displays a partial area of the pipe network diagram information on the CRT, the above-mentioned pipe network diagram information is enlarged and displayed according to the magnification.

When the overlapping state cannot be avoided even by the above-mentioned movement processing, the display color of the data is displayed differently from the other display colors (color information is added to the attribute information of the mapping memory). Can be realized by doing), or by blinking the data (also,
This can be realized by, for example, adding blinking information to the attribute information of the mapping memory) to display a warning to the operator <# 4, 5>, and leave it to the operator's judgment. The operator uses a keyboard, a mouse, or the like to perform an operation of artificially deleting the data displayed as a warning or displaying the data in an area outside the set range.

Furthermore, if the overlapping state cannot be avoided even by the above-mentioned movement processing, step <# 4, 5
＞ warning display is not displayed, but the ducts and nodes that correspond to the data that cannot be avoided in the network diagram are enlarged and copied to the area of the internal memory other than the area used to display the network diagram. Then, the overlapped state may be eliminated by arranging numerical data of the same size as the size used in the entire network diagram for the enlarged pipeline or node.

Therefore, the computer forming the solver unit 2 and its peripherals, and the program executed by the solver unit 2 serve as an analyzing means for executing the fluid analysis on the fluid supply network. Then, the computer constituting the above-mentioned post-processor unit 3, its peripheral devices, and the program executed by the post-processor unit 3 analyze the analysis result by the solver unit 2 in a pipe network diagram showing the arrangement of the fluid supply pipe network. It becomes a display processing means for displaying a numerical value at a predetermined place, and a judging means for judging the overlap of the display positions of a plurality of numerical information to be displayed on the network diagram, and when the overlap is judged, the display place is changed within the set range. It becomes a display position changing means, and further, when the overlapping of the display positions of the plurality of numerical information to be displayed on the network diagram is not eliminated even by changing the display position by the display position changing means,
Warning display means that allows the operator to identify the corresponding numerical information,
Alternatively, it is a display mode changing means for displaying a numerical value after enlarging and displaying the portion of the network diagram relating to the corresponding numerical information.

Another embodiment will be described below. In the above embodiment, an example of expanding and copying to the area other than the area used for displaying the network diagram in the internal memory has been described as the display mode changing means, but it is used for displaying the network diagram. You may enlarge and copy to the area | region which is in an area | region and is unnecessary for display. Further, when displaying a partially enlarged pipe network portion on a CRT or the like, a window system or the like can be appropriately used to display it with good visibility. In the above embodiment, the water supply pipe network was described as the fluid supply pipe network, but the fluid supply pipe network is not limited to this, and can be applied to a gas supply pipe network, a hydraulic circuit network, and the like.
