Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a drawing management apparatus for managing facility drawings, such as water and gas piping systems, electricity and telephone wiring systems, by converting them into digital information.

[Conventional technology]

2. Description of the Related Art Conventionally, status management of facilities such as piping for water, gas, electricity, telephones, and wiring systems has been performed using drawings drawn on paper or polyester film. At this time, if a change occurs in the facility, it is necessary to correct the drawing. All the work of correcting the drawings must be performed manually, which requires much labor and time, and has a problem that the rate of erroneous writing is high. In order to solve this problem, for example, as described in Japanese Patent Publication No. 61-9667, it has been proposed to convert facility drawings into digital information and manage them. In order to manage the facility drawings by converting them into digital information, a large number of facility drawings (topographic maps, system diagrams, symbol maps, etc.) stored in the file device are displayed on the display device on a monitor. In addition, the work of correcting the drawings is also displayed on the display device.

[Problems to be solved by the invention]

As described above, when a facility drawing is managed by digital information, an operation input device such as a tablet, a mouse, and a keyboard is used to display a monitor on a display device or perform a work of correcting the drawing. It is desirable that the selection of operation items such as monitor display and correction work can be performed in as simple a procedure as possible. To select an operation item by a tablet, a list of operation items is put in advance on a tablet surface, and a corresponding operation item is selected with a stylus pen according to the operation item. On the keyboard, operation items are assigned to function keys and operated with a single touch, or operation items are selected by a combination of keys. When the operation input device is a tablet or a keyboard, if the number of operation items increases, it is unavoidable that the operation becomes difficult. The table on the tablet surface becomes too large or the operation item column becomes too small, making it difficult to operate the tablet. In addition, the keyboard lacks function keys, and the frequency of key operations increases as the number of key combinations increases.

On the other hand, in the case of a mouse, an icon for displaying an operation item is displayed on the display device, and the operation item is selected by moving a cursor to the corresponding icon. Therefore, the operation procedure can be easily performed by switching the display contents of the icons for each function even if there are many operation items. However, even if a mouse is used as an operation input device, the cursor must be moved each time an operation item is selected, and operability is not improved even when the same operation item is used repeatedly, which is troublesome. Have.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a drawing management apparatus with improved operability for selecting an operation item.

[Means for solving the problem]

According to the present invention, at the start of an operation for displaying a facility drawing on a display device or performing a drawing correction operation, a cursor automatically matches the position of an icon for displaying the operation item with the highest priority and the most frequently used operation item. Let it do.

[Action]

The mouse cursor for selecting an operation item automatically moves to the position of the icon displaying the operation item to be operated according to the frequency of use of the operation item. Thus, when the same operation is repeated, the operation item can be selected without moving the cursor to the corresponding icon each time. Therefore, the operation can be easily performed, and no erroneous operation can be performed.

〔Example〕

 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 2 is a basic configuration diagram of a drawing management apparatus according to an embodiment of the present invention.

In FIG. 2, facility drawing data is stored in the file device 203. The facility drawing data includes graphic data such as a topographic map and a control map, and attribute data represented by characters and numerical values, such as a town name, a personal name, a management aperture, and a pipe type, related to the graphic. The stored graphic data is input from a drawing input device 204 which scans a drawing drawn on a paper at regular intervals, converts the drawing into gray scale according to the gray scale of the read data, obtains a digital image, and obtains coded data. Facility drawing is 3rd
As shown in FIG. 7A, the drawing is composed of a plurality of drawings, and each is divided to form a graphic data file. Fig. 3 (b)
The lengths X ₀ and Y ₀ in the X and Y axis directions are determined by the drawing size as shown in FIG. These graphic data are
The data storage structure is hierarchically separated from roads, house frames, and pipelines as shown in FIGS. These data are superimposed on each layer as necessary to form graphic data as shown in FIG. 4 (a). On the other hand, the attribute data is input to the file device 203 using a data input device 208 such as a keyboard 206 or a floppy disk capable of inputting data collectively. In order for the operator to operate the mouse 207 to display the drawing on the display device (CRT) 205, the operator first operates the mouse 207 to move the cursor CU to the function selection icon displayed on the CRT screen. To specify. When the "draw drawing" icon is specified, the central processing unit (CP
U) 201 retrieves the corresponding drawing data (graphic data and its attribute data) from the file device 203 and temporarily stores it in the main memory 202. The main memory 202 functions to store a program for executing processing such as search and editing of screen data and data being processed. After the drawing data temporarily stored in the main memory 202 is edited by the CPU 201 in accordance with the effective display coordinates of the display area of the CRT 205, the
Displayed on T205. The operator can know the contents of the target drawing from this display screen. In order to grasp a small part, the part is enlarged and displayed. For this purpose, the cursor CU is moved by the mouse 207, for example, 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, the main memory
A part of the corresponding drawing data stored in 202 is enlarged / reduced through the CPU 201 and displayed on the CRT 205.

Next, an operation of retrieving a target drawing from the file device 203, displaying the drawing data on the CRT 205 after editing, and correcting the display contents will be described with reference to FIG.

FIG. 1 shows a main part of an embodiment of the present invention.
FIG. 5 is a diagram illustrating an example of an operation item selection processing unit of FIG. In FIG. 1, a display surface 101 is a mouse operation icon area for selecting a function for searching and correcting a target drawing.
102, a drawing display area 103 for displaying a drawing searched by a mouse operation. The selection operation of the mouse operation icon area 102 is processed according to the following procedure.

Display display surface 1 using mouse 207 shown in FIG.
The cursor CU that moves in a pair with the operation of the mouse 207 is moved to the icon area 102 on 01, and a command for selecting an icon displaying a target operation item is issued. This selection command is CP
The icon input to the operation input position detection unit 104 of U201 and selected from the cursor coordinate position (X ₀ , Y ₀ ) is determined. The operation frequency processing unit 105 adds the frequency of the icon selection result to the operation item total use frequency table 107 in the main memory 202. Further, the usage frequency priorities are determined in the descending order of the total value of the operation item total usage frequency table 107, and the usage frequency priority table 108 is created.

On the other hand, the cursor position determining unit 106 refers to the use frequency ranking table 108 and determines the priority of whether the next icon should be selected for the icon selected and operated by the mouse 207. As a result, the icon selection position to be operated next is automatically determined, and the cursor automatically moves to the corresponding icon area on the display screen via the display editing unit 109.

FIG. 5 shows an example of display contents of icons for each operation item level in the icon area 102. The icons are designed to be selected by moving the cursor from among a plurality of functions for each operation item level. For example, when the "draw drawing" icon is selected at the operation item level 1, the next level 2
Then, the operation item corresponding to the icon is switched and displayed in the icon area 102 next. At this time, in the present invention, the cursor automatically moves to the frequently used icon position.
Next, assuming that this icon is an item to be selected, when a selection operation is performed by pressing a mouse button, after the corresponding process is completed, the next level 3 icon is displayed in the icon area 103, and the cursor is moved to level 2 As in the case of, the icon is automatically moved to the icon position having the higher priority.

Next, the processing of the operation frequency processing unit 105 will be described with reference to FIGS. FIG. 6 shows a configuration example of the operation item use frequency total table 107 for accumulating how many times the use frequency has been performed for each operation item when the corresponding icon is selected by operating the mouse 207. The operation item use frequency total table 107 corresponding to the operation item level icon area 102 shown in FIG. 5 stores the use total count value for each icon. This cumulative usage count value may be a total cumulative value in the past or a cumulative value within a certain period. In any case, an effective priority can be obtained for the latest operation item.

FIG. 7 shows a configuration example of the use frequency priority table 108. The priorities of the icons are assigned in descending order of the cumulative use frequency in the cumulative use frequency table 107 for each operation item in FIG. 6, and the next cursor position at the time of mouse operation is determined. With this, if the operation item to be selected by the operator does not match the highest priority icon,
By simply pressing the mouse button, the user can move to the second priority order at a time, and the operation can be performed easily and quickly.

The operation item is selected in this manner. At the start of the operation, the cursor is automatically moved to the position of the icon displaying the operation item with the highest priority. Therefore, the operation of moving the cursor with the mouse for selecting an operation item can be reduced, and the operation can be simplified.

In the embodiment of FIG. 1, priorities are determined as shown in FIG. 7, and the cursor is moved by operating a mouse button. Therefore, the operation item can be easily selected even when the item to be operated next is not of the highest priority.

〔The invention's effect〕

As described above, according to the present invention, the operation input selection for displaying or modifying the facility drawing preferentially causes the cursor to move to the next operation item position based on the frequency of use for each operation item. When there are many, you can choose quickly.

In the above-described embodiment, the operation items having the highest priority are displayed. Although the cursor is moved to the position of the icon, the position of the icon for displaying the operation item with the highest priority is determined in advance, and the display position of the icon is changed by fixing the position of the cursor at the start of the operation. It is clear that they may do so.
