Description

The present invention relates to a method for displaying a facility drawing managed by a host computer on a screen, and in particular, to data maintenance of a maintenance input graphic element for an existing facility drawing, That is,
It is about how to establish, change or remove.

B. Summary of the Invention The present invention uses a host computer and a graphic display device to create a maintenance drawing by drawing a maintenance input graphic element in a color according to the maintenance type separately from the current equipment drawing by a maintenance input operation, In the method of performing the maintenance input echo display by superimposing this and the current equipment drawing, the above-mentioned superimposed drawing is traced as far as the equipment belonging to the group from the rising equipment of the group to which the maintenance-related equipment belongs continues. By re-recognizing the group to which maintenance-related equipment belongs, even if the group to which equipment belongs automatically changes due to maintenance input, the group can be managed correctly and accurately.

C. Conventional technology In public works such as electricity, water, and gas, use drawings depicting the facilities on street maps for planning and managing facilities such as power lines, telephone lines, and gas pipes laid in the area. doing.
It is necessary to reflect information collected from each district in such drawings, but recently, in order to process information accurately and at high speed, and to efficiently perform operation work, equipment drawing display devices using computers have recently been used. Is used.

This device is composed of a host computer 1 and a graphic display device 2 as shown in FIG. 2. The host computer 1 manages a drawing in which facilities corresponding to a street map are displayed in a superimposed manner, and is designated when a display is requested. The drawing data in the specified range is cut out and transmitted to the graphic display device 2, and the graphic display device 2 registers the drawing in the segment buffer, and then draws and displays the drawing in the frame buffer. In recent years,
When the system is started, all the drawing data is transmitted from the host computer 1 to the graphic display device 2 to register a segment. When a display is requested, the host computer 1 designates only the display range on the graphic display device 2, and the graphic display device 2 displays the display range. A method of cutting out and displaying the drawing data has been developed. In this case, the transmission of a large amount of data to the graphic display device 2 and the process of registering a segment are not required at the time of display, and a higher-speed display is realized. You.

Here, the graphic display device 2 will be briefly described with reference to FIG. Figure 2 ₁ is a host interface (HI
F), 2 ₂ are segment buffer (SB), SB2 ₂ is a memory for storing the drawing data for describing expression (number, symbol) as a hierarchical structure.

To the drawing data stored in the SB2 _2, display the required range (rectangular region defined by the world coordinate values)
Of the drawing data is performed. The clipping processing, display matrix calculator for performing translation and rotation transformation of the graphic (MTX) 2 _3, CRT monitor (CRT) 2 ₄ clipping unit for removing a portion protruding a viewable area that corresponds to (CL
P) ₂₅ mag is prepared. Furthermore, the line segment of the drawing data of the cut-out description expression is turned ON / OFF of the bit on the frame buffer (FB) ₂₆ corresponding to the display position coordinate.
Digital differential analyzer unit (DDA) 2 ₇ to expand the information is provided. Video interface (VIF) 2 ₈ causes the reproduced video signal thereby to address the bit string corresponding to each pixel by reading the contents of FB2 ₆ to the look-up table (LT) 2 ₉ of reading the color code CRT 2 ₄ Do things and so on. 2 ₁₀ central processing unit for analyzing of the input information of the host computer (CUP), 2 ₁₁ is an input device for inputting various information by an operator (IM).

Such an equipment drawing display device has a maintenance function of a drawing that is naturally managed. The maintenance input operation is required to have good operability in order to ease the burden on the operator and improve work efficiency. As one of the functions to meet the demand, a graphic element input for maintenance is displayed in a maintenance type sequence (new / change /
(Removal).
That is, when a graphic element is removed, the graphic element is the removal color, when a new graphic element is installed, the new graphic element is the new color, and when the graphic element is changed, the original graphic element is the removed color and the new graphic element is the new one. Echo by color.

In order to realize such an echo display, a method of directly processing the data content of the current drawing in response to the input can be considered. For example, when removing a graphic element, the graphic element is deleted from the current drawing.
However, this has the following problems. First, if a trouble such as a system failure occurs during a maintenance input operation, data contents cannot be guaranteed. That is, there is a possibility that the contents of the original current drawing cannot be restored. Secondly, when the maintenance input operation is stopped and the original current drawing is displayed, a process for returning the drawing elements for which the maintenance input has been performed to the current contents must be performed one by one, which has a processing time.

In order to solve such a problem, the present inventors are studying the following method as an invention on which the present invention is based. That is, the maintenance input operation creates a maintenance drawing by drawing the maintenance input graphic element in a storage area for the maintenance drawing at a designated position corresponding to the current drawing in a color corresponding to the maintenance type (new, changed, or removed), In this method, the maintenance input graphic element is echo-displayed by superimposing this drawing on the current equipment drawing and displayed on the screen, and the screen is returned to the contents of the current equipment drawing by deleting the maintenance drawing from the screen. This method is advantageous in that the current equipment drawing can be protected from the maintenance input processing, and the screen can be easily and quickly returned to the current equipment drawing content.

D. Problems to be solved by the invention The equipment (gas pipes, water pipes, distribution lines, etc.) to be managed by this device is for supplying gas, water, electricity, etc. to the target block. Individual facilities form a group for each target block. For example, in the case of distribution lines,
The individual equipment is a rising cable, a section switch, a link switch, a line, a customer supply device, etc. The line is extended from the rising cable in a branch shape, and a customer supply device is arranged at each terminal of the branch line. Sectional switches are installed at several places on the track to constitute one distribution line. A link switch is installed on the line connected to other distribution lines, and it is used as a boundary with other distribution lines. FIG. 4 shows such a distribution line diagram, and the range surrounded by the dotted line is the range of the equipment belonging to one distribution line.

In the case of such an equipment drawing, it is necessary to manage the group to which each equipment belongs. The reason is that firstly, it is necessary for facility management, and secondly, it is necessary to perform data search or data update in the group to which the user belongs. However, when performing the maintenance input operation of the equipment drawing, it is quite troublesome for the operator to input the belonging group for each maintenance equipment one by one. Further, when a maintenance input is made for a certain facility, another facility whose belonging group is automatically changed in some cases may occur, and it is difficult to correctly and surely input the information. FIG. 5 shows this example.
Change the linked switch 3A connected to the distribution line and b distribution line to the manual division switch 3B, and change the manual division switch 4A belonging to the b distribution line
Shows the maintenance of changing to the link switch 4B.
When the maintenance input is performed for the linked switch and the manual switch, the line surrounded by the linked switch and the manual switch automatically changes to the distribution line from the b distribution line, as is clear from the figure. Becomes Recognition of the affiliation of such equipment becomes increasingly difficult with complicated maintenance. Further, since the maintenance is not a direct maintenance, there is a possibility that the user may not notice or forget the input. Therefore, it is not advisable to input the group to which the individual equipment belongs in the maintenance input operation.

The present invention has been made under such a background, and the purpose is to automatically change the group to which the equipment belongs in connection with the maintenance input while obtaining the advantages of the above-described method. Another object of the present invention is to provide a method for managing a group to which the user belongs correctly and reliably.

E. Means for Solving the Problems In the present invention, a maintenance input operation draws a maintenance input graphic element in a storage area for a maintenance drawing at a designated position corresponding to the current equipment drawing in a color corresponding to the maintenance type. The maintenance drawing is created, and the drawing is superimposed on the current equipment drawing and displayed on the screen to perform the echo display of the maintenance input graphic element.

Then, when the maintenance input operation is completed, the group to which each of the equipments for which the maintenance has been input is taken out. This belonging group is the group to which the existing equipment belongs when the equipment is changed or removed, and is the group to which the existing equipment is connected when the equipment is newly installed. Also, as in the case of a distribution line link switch, it does not have its own group, but is located at the boundary between the groups and connects them (hereinafter referred to as boundary equipment).
For, take out the group to which it is connected.

All equipment of the above group in the current equipment drawing,
All the equipment entered in the maintenance drawing will be processed.

In the current equipment drawing and the maintenance drawing, for each belonging group extracted in the above-described processing, the equipment sequentially following the rising equipment is followed until reaching the boundary equipment or the equipment to be removed or there is no more equipment to be removed. Normally, the current equipment drawing is traced, and if the maintenance input equipment corresponding to the existing equipment is present in the maintenance drawing, switching to the maintenance drawing is performed. If there is no equipment to be traced in the maintenance drawing, the flow returns to the current equipment drawing again. This processing is equivalent to tracing a drawing in which the current equipment drawing and the maintenance drawing are superimposed. The belonging group of the equipment thus traced is recognized as the same belonging group as the rising equipment.

Of the equipment to be processed, equipment that cannot be found is recognized as having no belonging group.

To end the maintenance process and return the screen to the contents of the current facility drawing, the maintenance drawing is deleted from the screen.

F. Embodiment The present invention will be described with reference to FIG. The screen of the power distribution equipment shown in FIG. 5 is now drawn on the screen 5, and when a maintenance input operation is performed on this drawing, a storage area for the maintenance drawing of the host computer (a screen as a virtual screen based on coordinates). shown are) 6, for example, mains section switch S ₁ and the manual section switch S ₃ is in the removal color, and line S ₂ is drawn at a specified position corresponding to the respective current facilities drawing in new colors.

Then, the maintenance drawing is superimposed on the current equipment drawing so as to be preferentially displayed and displayed on the screen, so that the maintenance input graphic element is changed, and the transfer target graphic element is echo-displayed. At the bottom of FIG.
This shows a screen displaying the removed and newly installed state of the graphic elements to be removed and newly installed after echo display.

Here, when ending the maintenance input operation, first, the distribution line to which the maintenance facility belongs is searched. In the case of this example, the distribution lines belonging to the switches S ₁ and S _{3 to} be removed are the a distribution line and the b distribution line, respectively, and the distribution lines belonging to the new line S ₂ are the distribution lines a and b. It is.

Next, all the facilities (surrounded by dotted lines) belonging to the a and b distribution lines in the current facility drawings and all the facilities (S ₁ , S ₂ , S ₃ ) in the maintenance drawings are processed. First, for a distribution line, from the rising cable 7A to the trunk line switch 7B
However, since the link switch 7C, which is a boundary facility, is connected to one of the branch ends of the subsequent distribution line, the branch end is not traced any further. Also since the other of the branch end maintenance entry facility ie mains section switch S ₁ corresponds to the existing mains sectionalizing switches 7D is depicted in maintenance drawings, it does not follow even more for the other branch end . The same procedure is followed for the b distribution line, but the manual switchgear S ₃ to be removed
It does not follow thereafter. In addition, the distribution line S ₂
Although but traced to the subsequent equipment for depicted in maintenance surface, do not follow any more since linkage switch 7E is connected to the distribution line S _2. The belonging group of the equipment thus traced is recognized as the same belonging group as the startup equipment.

As shown in FIG. 1, equipment surrounded by the same dotted line is recognized as belonging to the corresponding distribution line. Incidentally current equipment drawing b manual section switches S ₃ and subsequent lines removal target in the distribution line is a processing target is recognized that there is no affiliation distribution line for not followed.

G. Effects of the Invention As described above, according to the present invention, each belonging group of the maintenance equipment is searched, and the equipment sequentially following the starting equipment of each of the searched belonging groups is traced, and the belonging of the traced equipment is searched. Since the group is recognized as belonging to the same group as the startup facility, the following effects are further obtained.

a. In the maintenance input operation, it is not necessary to input the group to which the maintenance-related equipment belongs, so that the operation can be simplified and the operation can be simplified.

b. At the time of maintenance input operation, the group to which equipment other than the equipment directly subject to maintenance may be automatically changed in connection with maintenance. In this case, it is difficult to recognize the affiliation by the method of inputting the affiliation group of the equipment one by one, or there is a risk that the modification of the affiliation group is not noticed because it is not the object of direct maintenance. Can manage.
