Abstract

PURPOSE:To easily retrieve the contents of a desired drawing by editing and displaying the drawing data stored temporarily in a main memory in accordance with an effective display area. CONSTITUTION:When a 'drawing read' icon is designated, a CPU 201 retrieves the corresponding drawing data (and its attribute data) out of a file device 203 and stores temporarily the retrieved data in a main memory 202. Then the data stored in the memory 202 are edited by the CPU 201 in accordance with an effective display area of a display device (CRT) 205 and shown on the CRT 205. Under such conditions, for instance, a cursor is moved by a mouse 207 and an optional rectangular area is designated at both ends on a diagonal line through the display area of the CRT 205. Then the optional area is magnified or reduced in an optional magnification or reduction ratio. Thus an operator can easily retrieve a desired drawing based on the displayed drawing.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawing management method and apparatus for converting a drawing of a gas piping system, electricity, water distribution system of a telephone, etc. and attribute information of each object to be managed on this drawing into digital information. Regarding

[0002]

2. Description of the Related Art As a conventional device for retrieving and displaying a drawing from attribute information of an object to be managed, there is one disclosed in Japanese Patent Application Laid-Open No. 1-10383. According to this conventional technique, a telephone number, an address, a map, etc. are stored as the attribute information of the management target object, and the telephone number or the address is input and designated to read out and display the corresponding drawing.

[0003]

In the above prior art, the drawing is searched from the telephone number or the address, so that there is only one drawing. However, for example, when examining the location of a pipe that has passed a certain number of years to replace an old water pipe in a water supply facility, it is common that there are multiple water pipes that match the conditions. . Regarding the measures against such a case, the above-mentioned conventional technology does not consider.

Further, in the above-mentioned prior art, since a detailed drawing having a managed object that meets the conditions is directly displayed,
In the case where hundreds or more drawings are to be managed, there is also a problem that it is difficult to know to which region of the whole the displayed detailed drawings correspond.

An object of the present invention is to easily search and display which part of the whole the managed object which meets the condition exists even when the managed object which meets the condition exists in a plurality of drawings. It is an object of the present invention to provide a drawing management method and an apparatus therefor.

[0006]

The above object is to provide a detailed view corresponding to a divided drawing when one of the divided drawings obtained by displaying the entire management target area as an index drawing on the screen and dividing the index drawing with a mesh is selected. When displaying a partial drawing on the screen, when an attribute condition for classifying a managed object is specified, all of the divided drawings corresponding to the detailed partial drawing in which the corresponding managed object that matches the attribute condition is drawn are simultaneously displayed. This is achieved by displaying the index diagram separately from other divided drawings and displaying the distribution of the corresponding managed object on the overall view.

[0007]

[Operation] As an attribute condition of a managed object, in addition to an attribute condition for individually specifying the managed object, an attribute condition for classifying the managed object (for example, by year of laying pipe, pipe type of pipe, etc.)
When the attribute condition is designated, it is possible to search for the management target objects existing in a plurality of drawings. Also, when displaying the search results, rather than displaying the detailed drawing directly on the screen, the divided drawing corresponding to the detailed partial drawing is distinguished from other divided drawings on the search drawing divided by mesh. Since it is displayed as a whole, the general distribution of the relevant managed object in the whole becomes clear.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a basic configuration diagram of a drawing management apparatus which is an embodiment of the present invention. In FIG. 2, the file device 20
Facility drawing data is stored in 3. Facility drawing data includes graphic data such as topographic maps and pipelines, attribute data that identifies individual managed objects such as town names and individual names related to individual figures of managed objects such as pipes, management diameters, and pipes. It consists of attribute data that classifies managed objects such as species. Each attribute data is expressed by a character / numerical value. The stored graphic data is a drawing input that obtains coded data by obtaining a digital image and converting the drawing written on a paper into a gray scale according to the shade of the read data at regular intervals with a digitizer or scanner. It is input from the device 204. As shown in Fig. 3 (a), the facility drawing consists of multiple detailed partial drawings (1, 2,
3, ..., N), each of which is divided into a graphic data file. The figure data is shown in a Cartesian coordinate system as shown in FIG. 3 (b), and in the drawing size, its lengths in the X and Y axis directions X0 and Y0.
Is decided. These graphic data have a data storage structure that is hierarchically separated from roads, house frames, and pipelines. These data are made into graphic data by superposing each layer as required.

On the other hand, the attribute data is input to the file device 203 using a keyboard 206 or a data input device 208 such as a flexible disk capable of inputting data collectively. To display a drawing on the display device (CRT) 205 by operating the mouse 207, the operator first operates the mouse 207 to move the cursor CU to the function selection icon displayed on the CRT screen. And set. When the "read drawing" icon is specified, the central processing unit (CPU) 201 retrieves the corresponding drawing data (drawing data and its attribute data) from the file device 203 and searches the main memory.
It is temporarily stored in 202. The main memory 202 has a function of storing a program for executing processing such as search and edit of screen data and data being processed. The screen data temporarily stored in the main memory 202 is displayed on the CRT 205 after being edited by the CPU 201 according to the effective display coordinates which is the display area of the CRT 205. The operator can know the target drawing content from this display screen. In addition, in order to grasp the detailed part, the part is enlarged and displayed.
For this purpose, for example, the cursor CU is moved by the mouse 207, and a rectangular arbitrary area is designated from both ends on the diagonal line from the CRT display area and enlarged or reduced to an arbitrary magnification.
Specifically, a part of the corresponding drawing data stored in the main memory 202 is enlarged / reduced and edited via the CPU 201 to C.

The mouse 207 is used to select a function from the mouse operation icon area 102 and to indicate a position on the drawing or table displayed in the drawing display area 103, and the keyboard 206 is used to input a condition value of an attribute to be searched. Inputs from the mouse 207 and the keyboard 206 are captured by the CPU 201. Blocks 111 to 117 in the CPU 201 indicate processing steps. First, the input from the keyboard 206 is taken into the CPU 201 according to the operation input step 111. In the following, the expression of the functional part is used instead of the expression of the step.
In the file device 203, an index map file 107, a drawing file 108, an attribute file 109, a grouping file 101
Is stored.

The attribute file 109 is, as shown in FIG.
It is managed in files that are divided into facility units with the same attribute contents such as water pipes and water supply devices, and the attribute data of each facility is stored in a tabular format. In the grouping file 110, as shown in FIG. 4B, the correspondence between attributes and figures is the drawing number and the figure that is the consistent number for the figures in the drawing.
For NO., The corresponding attribute file name and the record number in the corresponding attribute file are stored in the form of a correspondence table.

Specifically, the attribute file shown in FIG.
It is filed in the categories of water distribution pipes, water supply devices, and so on. For example, in the case of water distribution pipes, there are three classifications of NO.
100-several thousands), and the diameter of the distribution pipe (250,
100, 150), pipe type (ACP, DIP, CIP), extension pipe length (335.6, 73.5, 110.0, (meter)), facility year (S5
3, S37, S28) are set as data.

Further, the grouping file of FIG.
Drawing No. (15, 23,
6), Drawing No. (385, 26, 316, 823), Attribute file (water pipe, water supply device, water supply device, water pipe), Attribute No. (256, 113)
6,635,2758). Drawing NO. Is the drawing number (1, 2, ..., N) segmented in FIG. 3 (a), and figure NO. Is a number that identifies the figure in each drawing (that is, the drawing is a figure 4), and the attribute file is shown in Fig. 4 (a).
Attribute file name, and the attribute NO. Indicates the attribute number (the leftmost number in FIG. 4A) in the attribute file.

Next, the relationship among the functions, operations, and displays of the functional units 111 to 117 in the CPU 201 will be described with reference to FIGS. Here, FIG. 5 is a flow chart for operation and display when retrieving a drawing from attributes, and FIGS. 6 to 10 show respective display examples. In the following example, the distribution pipe is searched from the drawing of the water supply facility by year and pipe type.

When a drawing is searched for by attributes, the mouse 207 is first used to select the icon item "attribute search" in the icon area 102 (FIG. 1) (step 501 in FIG. 5). The selected icon item is input by the operation input function unit 111, and the attribute search control function unit 112 is also operated. All the subsequent inputs from the mouse 207 and the keyboard 206 are passed to the attribute search control function unit 112. The attribute search control function unit 112 takes in the configuration of the attribute file 109 via the attribute search function unit 115, and displays the attribute file list via the display / edit function unit 117.
Display on the drawing display area 103 (FIG. 1) (step 50 in FIG. 5)
1A).

FIG. 6 shows a display example of this attribute file list. In the figure, 5 types of attribute files (1 water pipe, 2
A water supply device, 3 fire hydrants, 4 gate valves, 5 pressure reducing valves) are shown. This list is a list of facilities. Note that all subsequent display is performed via the display editing function unit 117.

Next, 1 out of the attribute files shown in FIG.
One search target is selected (step 502 in FIG. 5). This selection is made with the mouse 207. Upon receiving this selection result, the attribute search control function unit 112 displays the search condition list according to the structure of the attribute file 109 that has been fetched (step 502 in FIG. 5).
A). An example of this display is shown in FIG. FIG. 7 (a) is an example of selecting a water distribution pipe, and shows an example of five attribute data "1 NO., 2 caliber, 3 pipe types, 4 extension, 5 years" as its contents. However, in FIG. 7 (a), blanks are shown in the brackets [] for each item.

Next, a search condition is input to the search condition input list from the keyboard 206 (step 503 in FIG. 5).
The attribute search control function unit 112 (FIG. 1) displays the input conditions as shown in FIG. 7B (step 502A in FIG. 5). Figure 7 (b) shows “ACP” as the pipe type and 1965 as the facility year.
There are two input conditions before year 0 (≦ S30). That is, FIG.
According to the display content in (b), it means that it is required to search for water pipes whose pipe type was ACP and which was laid before 1955.

When the search condition input step 503 is completed,
The attribute search control function unit 112 (FIG. 1) gives the input search condition to the attribute search function unit 115 (FIG. 1). Attribute search function section 1
15 searches the attribute file 109 for a record of attribute data that matches the search condition, and retrieves the result from the attribute search control function unit 112.
Return to. Here, a record is a figure that constitutes one drawing of FIG. 3B, and a number is added to each figure. This number is called a record number or figure number.

The attribute search control function unit 112 supplies the record number of the attribute data to the grouping figure search function unit 116 in order to obtain the correspondence between the attribute data obtained above and the drawing data. The grouping figure search function unit 116 searches the correspondence table of attributes and figures stored in the grouping file 110 shown in FIG. As a result, the drawing number corresponding to the record number of the given attribute data and the figure number in the drawing are searched, and the result is searched for as the attribute search control function unit 112.
Sent to

The attribute search control unit 112 posts the attribute search result list and the corresponding drawing position on the index map in order to post to the user the correspondence between the attribute data that matches the search conditions obtained above and the drawing. It is displayed (503A to 503C in FIG. 5).

An example of this display is shown in FIG. The data string 801 in the upper right of the figure is the attribute search result list, and it can be seen that five examples were extracted as the list of ACP pipelines before 1955 (502A). The map display example excluding the list in FIG. 8 is an index diagram, and six town names of A town to F town are displayed. The mesh division drawing corresponding to the coordinate position of the list on this index map is displayed with distinction (shaded in the example shown) (8
03) has been done (step 503C in FIG. 5). In the figure, five divisional drawings are displayed separately for each of the five lists.
The index map is the one stored in the index map file 107, and is the one that the index map search unit 113 reads and displays.

Next, in order to check the correspondence between individual lines on the list (a list of 5 lines in FIG. 8) and the drawing, line designation on the attribute search list (step 504 in FIG. 5) is performed by the mouse 207. . As a result, the designated line is selected and highlighted (step 504A in FIG. 5).

FIG. 9 shows an example of highlighted display. The second line of the list is selected with the mouse and displayed in parentheses (901). In addition, the divided drawing in B town at the position corresponding to the second line on the index diagram is highlighted (in the example shown, a stitch pattern is displayed). Has been done. Next, in order to retrieve and display the target drawing, the drawing position indication (step 505 in FIG. 5) displayed on the index drawing is moved by the mouse 207.
(Step 505 in FIG. 5). In the example of FIG. 9, the highlighted B town division drawing is designated. Thereby, the drawing display command corresponding to the designated position on the index map 802 is sent from the attribute search control function unit 112 to the drawing search function unit 1.
14, the drawing search function unit 114 once reads the corresponding drawing data from the drawing file 108 into the main memory 202, and then displays the drawing 1001 as shown in FIG. 10 via the display editing function unit 117. .

Here, the attribute search control function unit 112 displays the partial list 1002 of the attribute data corresponding to the drawing 1001 displayed from the previous attribute search result list 801, and the facility figure corresponding to each attribute data on the list. The existing position 1003 of is displayed on the displayed drawing 1001. The individual correspondences between the partial list 1002 of the attribute data displayed here and the existing positions 1003 of the facility figures are highlighted by pointing a line on the partial list with the mouse, as in the index diagram. Incidentally, FIG.
Then, an example of existence of two corresponding places 1003 and 1004 in B town is shown.

Next, a search display is necessary for another drawing.
In the case of (step 506 in FIG. 5), the drawing search can be performed again by returning to the drawing showing where the drawing corresponding to the attribute search list shown in FIG. 8 is distributed on the index drawing.

According to this embodiment, it is possible to easily know how many water pipes are applicable by designating the year and pipe type, where they are distributed, and where in which drawing each is located. You can As a result, the work efficiency such as the number, distribution, and position confirmation of the corresponding pipelines for the replacement of aged pipes is improved. As examples of highlighted display, there are various examples such as color change and gradation change in addition to the pattern form example as in the previous embodiment.

According to this embodiment, when a drawing is searched for by an attribute, a list of attributes matching the search condition is displayed, and the drawing position where each figure corresponding to the list exists is displayed on the search drawing. , After highlighting the drawing position where the figure corresponding to the attribute specified in the list exists, on the index diagram above,
The relevant drawing can be searched and displayed. This allows you to search and display the drawing in which any of the figures exists when there are figures corresponding to the attributes that match the conditions in multiple drawings, and to know where the corresponding drawing is located as a whole. There is an effect that the drawing can be displayed with.

[0030]

According to the present invention, the attribute condition of the managed object is classified into the attribute condition of the managed object separately from the attribute condition for individually specifying the managed object (for example, by the year of installation of the pipe, It is possible to search for a management target object existing in a plurality of drawings when this attribute condition is specified. Also,
When displaying the search results, instead of displaying the detailed drawings directly on the screen, all the divided drawings corresponding to the corresponding detailed partial drawing are distinguished from other divided drawings on the search drawing divided by mesh. Since it is displayed in a diced form, the general distribution of the relevant managed object in the whole can be seen at a glance.
