Abstract

PURPOSE:To trace a route from a designated point to the following boundary and to detect a specified designated area of a drawing by designating from among plural ones that corresponds to the designated point on a specific, and retrieving and displaying a neighboring drawing that includes the designated point of the said route based on the relation between the virtual boundary part of the ending part of the above-said corresponding drawing and another neighboring drawing. CONSTITUTION:In the event of a water failure 104, the connection-states between the piping network and valves is checked, such a pipe as having a connection with a valve in a neighboring drawing is seelcted, an imaginary valve 103 is attached to the extreme of the piping network in the above-said corresponding drawing, and the neighboring drawing is retrieved by using the locating of the imaginary valve 103. This retrueval is executed in such a manner that a pipe route that comes to be closed loop between the designated location of piping of water failure and the valve, is tracted linearly, thus the water failure zone is limitted and finally determined.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a drawing search and display method, and in particular to a method suitable for quickly searching for a specified route area across a plurality of drawings converted into vector information. Related to drawing search and display method.

[Conventional technology]

Conventionally, attribute values such as topographical information and water pipe information were linked to geometric data such as topographic maps and water pipes to create a database, and when an arbitrary point was specified, a certain area within the same drawing was enlarged and the attribute data was Various facility drawing information systems to be displayed have been announced (“Pixel [PI

pp96-138), L However, in these systems, by specifying an arbitrary figure for a drawing that has graphical elements related to multiple drawings, such as an IJ''' water pipe, other corresponding drawings can also be automatically created. No consideration was given to the search method.

[Problem that the invention seeks to solve]

The above-mentioned conventional technology does not take into consideration the fact that when an arbitrary figure is specified, the range of that figure is related to multiple drawings.
There was a problem in that the related drawings had to be searched again or the search range had to be widened, making the search very time consuming.

An object of the present invention is to provide a drawing search that allows, when an arbitrary point on a predetermined route is specified, related drawings can be simultaneously searched across adjacent map surfaces where there is a section up to a predetermined demarcation part that connects to that route. The purpose is to provide a display method.

[Means for solving problems]

The present invention, which has achieved the above object, establishes the relationship between the system road shoulder and its demarcation part, with each drawing of a certain unit as a reference, and the system road shoulder in the relevant drawing is related to other adjacent drawings and the connection to the demarcation part. It is stored as data, and when a specific part of the system is specified, the data is searched and if there is a demarcation part connected to the system in the corresponding drawing in a drawing adjacent to the drawing of the specified part, the demarcation part is found. The section is displayed as if there is a virtual demarcation section at the end of the system in the corresponding drawing.

[Effect]

When you specify the relevant drawing of the specified part of a specific system path from among multiple drawings, the adjacent drawing that includes the specified area of the system is determined from the relationship data between the virtual demarcation part at the end of the thermal drawing and other adjacent drawings. The drawing will be searched and displayed.

As a result, a given designated area can be detected by tracing the system shoulder from the designated point to the next demarcation point.

A predetermined designated area can be known in a short time.

The display method of this embodiment is realized as follows using the apparatus having such a configuration. This will be explained below with reference to FIGS. 1 to 6.

Fig. 1 is a flowchart shown to explain the operations processed by the above-mentioned system, Fig. 2 is a diagram showing the piping for water cutoff area search, and an adjacent diagram shows the relationship with valve plugs, and Fig. 3 is a facility drawing. An explanatory diagram showing an example of data, FIG. 4 is a diagram showing an example of a display of water pipes in a water cutoff area.

In this embodiment, the corresponding drawings are specified for water pipe data that includes a water pipe 101 as a system route and a valve plug 102 as a demarcation part in facility drawings spanning multiple drawings ■ to ■. Water pipes 101 and valve plugs 102 that are connected between adjacent drawings are extracted and associated with the water pipes in the corresponding drawings as virtual valve plugs 103 to search for and display water cutoff areas. Namely.

In this embodiment, water pipe data of a facility drawing with a positional relationship as shown in FIG.
If there is a water outage point 104 (see Figure 2<b>) or a planned water outage at any point in Extract the valve plugs that are connected, and as shown in FIG. 2(b), attach a virtual valve plug 103 to the end of the water distribution pipe network in the corresponding drawing (Fig. 2〈■〉), and create a virtual valve plug 103. The corresponding adjacent diagram is searched based on the position of 103.

First, in step 401, a corresponding multiplier drawing is searched from facility drawings previously stored in the file device 303 of FIG. 5 and displayed on the CRT display device 305. This is displayed as follows. That is,
The facility diagram displayed on the CRT display N301 is shown in Figure 3 (
The drawing data 201 is as shown in FIG. 3(2) due to its graphical structure.

3. It is separated into a plurality of layers, such as the water pipe figure 204.

The facility drawing database can be used in the above layers (
202 to 204) are used in combination, but it goes without saying that what is important in the water cutoff area search display is the water pipe layer. Therefore, in this water outage area search display, water pipe M2
Of course, it is also possible to search in combination with other layers. Step 402 specifies the water cutoff location 104 shown in FIG. 2(b) on this water pipe drawing.

Next, step 403 searches the drawing search related block data of FIG. 4(b) in which the water pipe and valve plug on the drawing to which the water cutoff point 104 belongs are in an adjacent relationship.

Step 404 displays the curved tangent drawing as shown in FIG. 4(a) according to this drawing search related block data. moreover,
In step 405, a line is traced along the water pipe that forms a closed loop area between the designated water pipe water outage point and the valve plug, and the water outage area is limited. Step 406 changes the location of the water pipes in the water outage area determined in step 405, and displays the water outage area in an easy-to-identify manner.

The above embodiment has been explained using an example of water piping, but the application is not limited to this, but can also be applied to sewer lines, and can also be used to check the status of circuit breakers in power distribution lines during power outages, leak detection of gas piping, and traffic control, etc. This method can be applied to cases such as determining a detour route in the event of an accident.

As the operation is as described above, when performing a water outage area search display on facility drawings, specifying the relevant water outage location allows for a quick and automatic search for the drawings of the target area, and also allows for a large-scale database stored in the file device to be searched quickly and automatically. It is possible to load the minimum drawing data required for processing such as searching from the ``Drawing'' to the in-memory.
