Then, according to this file name, floor drawing file 3
And a scroll processing means for reading the corresponding adjacent floor plan from the list and performing the scroll processing for display.

FIG. 3 is a data arrangement diagram of the drawing positional relationship management information file 5 shown in FIG.

This file 5 contains the whole building drawing (1).
For each floor drawing (2) to (14), data such as a coordinate system drawing group, a building name, a floor (floor), a file name (section name), a lower left coordinate of each drawing, and an upper right coordinate of each drawing are arranged. I have.

That is, the coordinate system drawing group refers to the entire building drawing which does not belong to the coordinate system drawing group as the group No.
0, floor plans (2) to (1) of each building connected to each other
The coordinate system drawing group (15) consisting of
O. 1. Each floor drawing of each building connected to each other (11),
The coordinate system drawing group (16) consisting of (12) is group No. 2. Each floor plan of each building (1
The coordinate system drawing group (17) consisting of (3) and (14) is group No. 3 is assumed. The building name is distinguished according to A to G described in the whole building drawing. The floor (floor) uses floor numbers 0, 1, 2, and 3. The file name is represented by the building name + floor (floor). The lower left coordinates of each drawing and the upper right coordinates of each drawing represent actual coordinate data of each floor drawing from the origins of coordinates a, b, c (0, 0) determined for each drawing group.

Next, the reduction process and the scroll process of the system configured as described above will be described.

(1) Regarding reduction processing of the lower drawing adjacent to the lower drawing (see FIG. 4).

First, prior to the start of the operation of the system of the present invention, drawing positional relationship management information as shown in FIG. 3 is stored in the file 5 from the input device 1 or another device (not shown) via a network in advance.

When the data processing section 4 receives the system operation start instruction, the data processing section 4 clears unnecessary data in the various memories 6 and 7 and reads the reduction processing program from the recording medium 2 and temporarily stores the program in the buffer memory 6 and the like. After performing the initialization process for storing (S1), the floor drawing file 3
, The whole building drawing (1) is read out and displayed on the display unit 8 via the image memory 7 (S2, whole drawing display function).

In this state, the operator operates the input device 1
When, for example, the first floor drawing (5) of the building C is designated, the corresponding floor drawing (5) is read from the floor drawing file 3 and displayed on the display unit 8 (S3, S4, designated floor drawing display function).

Thereafter, for example, when a reduction instruction is input from the input device 1, the reduction processing of the designated floor drawing (5) is executed in accordance with a predetermined reduction rate or a reduction rate input from an operator, and the reduction result is designated. The floor drawing is displayed on the display unit 8 (S5 to S7, floor drawing reduction function).

The designated floor drawing (5) is a coordinate system drawing group No. 1 and the floor (floor) is the first floor, so the adjacent floor plan that can be reduced is:
(2), (3), (5) and (8).

Accordingly, when the data processing unit 4 receives a reduction instruction, the designated floor drawing (5) is reduced and displayed, but the screen display range of the display unit 8 is changed to the designated floor drawing coordinate range (30).
When the area exceeds the rectangular range of (0, 0) to (500, 200), the designated floor drawing (5) is set as the screen center, and adjacent floor drawings such as (3) and (8) are found from the drawing positional relationship management information file 5. The file names (B-1, D-1) of the floor drawings to be newly displayed on the display unit 8 are determined from the display coordinates of the floor drawings. And
File name (B-1, D-1 ) on the basis of the corresponding floor plan file _{3 (3} 3, _{3 8)} from the floor plan (3),
(8) is read out and reduced and displayed at the same reduction ratio (S8 to S10, adjacent floor drawing reduction function).

If the reduction ratio is further increased, not only the floor plan (3), (5), and (8) but also the floor plan (2) can be reduced and displayed at the same time.

(2) Scroll processing (see FIG. 5).

In this continuous scrolling process as well, similar to the reduced display process of the adjacent floor drawing, the whole building drawing (1) is read from the floor drawing file 3 after the initialization processing and displayed on the display unit 8 via the image memory 7. Yes (S1
1, S12, whole drawing display function).

When the operator designates, for example, the first floor drawing (5) of the building C from the input device 1 as described above, the corresponding floor drawing (5) is read from the floor drawing file 3 and displayed on the display unit 8 (S13, S14). , Designated floor drawing display function).

In this state, if there is a scroll instruction, it is determined whether the scroll is in the left or right direction (S1).
5, S16, scroll direction determination function).

The designated floor drawing (5) is the coordinate system drawing group No. 1 and the floor (floor) is the first floor, so the scrollable adjacent floor plan is
(2), (3), (5) and (8).

The data processing unit 4 starts scrolling rightward from step S16, and the screen display range of the scrolling result is the coordinate range (30) of the designated floor drawing (5).
When it exceeds the rectangular range of (0, 0) to (500, 200), a floor drawing (8) adjacent to the right is searched from the screen display coordinates of the drawing positional relationship management information file 5 and newly displayed on the display unit 8. The file name (D-1) of the floor plan to be executed is determined. Then, the file name (D
Based on -1) floor drawing file 3 _{(3 8)} from the floor plan reads (8), and displays while scrolling the floor plan (8) adjacent to the right (S17～S2
0, scroll processing function).

In the case of scrolling leftward in step S16, the floor drawing (8) is displayed while scrolling from the floor drawing (8) to the floor drawing (3) → floor drawing (2) adjacent to the left direction (S21 to S24, scrolling). Processing function).

Therefore, according to the above-described embodiment, when a file for managing the drawing positional relationship information of each floor of each building is created, when a reduction instruction or a scroll instruction is received, the file is currently displayed. The conventional floor drawing, which can only be performed in units of one floor drawing, is reduced because the floor drawing including the floor drawing adjacent thereto and the floor drawing adjacent to the floor drawing are reduced or the scroll processing is continuously performed across the adjacent floor drawings. Compared with the management, it is possible to easily grasp the connection between the floor drawings and, for example, the relation of the floor emergency road at the time of fire, and to appropriately manage the relation between the floor drawings.

(Second Embodiment) In this embodiment,
This is an example in which an upper / lower floor drawing for a floor drawing of a certain floor can be displayed.

In the conventional system, each floor drawing (1)-
(14) Since the mutual positional relationship information is unknown,
Floor drawing name to be displayed by the user (for example, building C-2)
Unless F) is designated each time, the floor plan of the upper floor or the lower floor cannot be displayed from the currently displayed floor plan. This means that if the building of the current location is unknown to the user, the floor plan names of the upper floor / lower floor cannot be designated, and the target floor drawing cannot be displayed.

In the drawing management system according to the present invention, the arrangement of each floor drawing of the building, the hardware configuration of the system, the drawing positional relationship management information file, and the like are substantially the same as those in FIGS. Will be described using the same reference numerals.

In this system, a program to be recorded on the recording medium 2 and a data processing unit 4 for executing processing according to the program are different from those of the first embodiment.

The data processing section 4 is constituted by a CPU and functionally reads out the whole building drawing from the floor drawing file 3 and displays it on the display section 8 as shown in FIG. A designated floor drawing display means 22 for reading and displaying the designated floor drawing from the corresponding floor drawing file 3 based on the floor designation from the input device 1, and a floor for a floor designation counter based on the upper / lower floor change designation. A floor change setting means 23 for changing and setting a value, and a file name is acquired from the drawing positional relationship management information file 5 based on the floor value of the floor designation counter, and an upper / lower floor drawing is obtained from the floor drawing file 3. Is read out and displayed on the display unit 8.

The recording medium 4 has a C
A floor change processing program as shown in FIG. 7 readable by the PU is recorded.

Next, the operation of the above system will be described with reference to FIG.

First, similarly to the first embodiment, the drawing positional relationship management information file 5 previously stores drawing positional relationship management information as shown in FIG.

Upon receiving the system operation start instruction, the data processing section 4 clears unnecessary data in the memories 6 and 7 and reads the floor change processing program from the recording medium 2 and stores it in, for example, the buffer memory 6 or the like. After performing the temporary storage initialization processing (S21), the entire building drawing (1) is read from the floor drawing file 3 and the image memory 7 is read.
Is displayed on the display unit 8 via the button (S22, building whole drawing display function).

In this state, the operator operates the input device 1
When, for example, the second floor drawing (6) of the building C is designated, the data processing unit 4 extracts the floor (floor) numerical value “2” from the drawing positional relationship management information file 5 according to the designated contents, While being set in the designation counter, the designated floor drawing (6) is read from the floor drawing file 3 based on the corresponding file name "C-2" and displayed on the display unit 8 (S23 to S2).
5, Designated floor drawing display function).

At this time, not only the designated floor drawing, but also the drawing positional relationship management information relating to the second floor floor drawing (6) of the building C in the drawing positional relationship management information file 5 may be displayed.

Thereafter, when the user inputs a floor change instruction from the input device 1, the data processing unit 4 determines whether the upper floor is specified or the lower floor is specified. The name of the building to be displayed, the floor, and the display coordinate position are determined from the, floor, and display coordinate position.

More specifically, if the upper floor is designated, +1 is added to the count value of the floor designation counter having the value of the currently displayed floor, and if the lower floor is designated, the currently displayed floor is added. -1 from the count value of the floor specification counter having the value
(S26 to S29, floor change setting function).

When the building name, for example, “C” and the floor (count value, for example, “3”) are determined as described above, the building name and the file name for the floor “C-3” are obtained from the drawing positional relationship management information file 5. And reads the floor drawing (7) of the upper floor from the floor drawing file 3,
The same processing is performed on the display unit 8 and the lower floor is designated (S30 to S34, change floor display processing function).

Since the display coordinates (lower left coordinates and upper right coordinates) of the floor drawings in the same building are the same, it is also possible to superimpose the floor drawings. Specifically, the floor plans (5), (6), and (7) can be displayed in the same position.

Therefore, according to the above-described embodiment, the user can set the current display floor position (at what floor of which building).
Even if is unknown, just specify the upper and lower floors of that floor,
The file name is acquired from the drawing positional relationship management information file 5 based on the building name, floor, and the like that are currently being displayed, and floor drawings on the upper and lower floors can be read and displayed on the display unit 8.

Therefore, conventionally, unless each floor drawing unit is explicitly specified, for example, as in the building C or 2F,
I could not move the floor plan of the upper floor / lower floor,
In this system, it is possible to move the floor plan of the upper floor / lower floor only by the relative designation (upper floor / lower floor).

(Third Embodiment) This embodiment is similar to the third embodiment.
This is an example in which a route search and a route display from a certain point in a building to a destination can be performed between floor plans of a building that is spread vertically and horizontally.

FIG. 8 is a diagram showing an example of an electrical hardware configuration of the floor plan management system for a building according to the present invention.

Since this system has substantially the same configuration as that of FIG. 2, the same parts are denoted by the same reference numerals and description thereof will be omitted. Particularly different points are that a graphic connection information file 31 is newly provided. is there.

The graphic connection information file 31 stores the exits and paths a, b, and a described in each floor plan shown in FIG.
Based on c,..., the coordinate system drawing group, the building name, and the floor are finely divided as shown in FIG. 9, and the figure numbers, the number of connections, and the connection figures are arranged for each of these divisions.

By the way, the figure number A-1-- means that there is an exit on the first floor of the building name A, and A-1-a means the building name A.
Means that there is a passage a on the first floor. The graphic numbers have the same meaning as described below. The number of connections means the number of connected figures on the right side of the figure, that is, the number of connected figures.
The connection graphic indicates a connection relationship between the passages. For example, a graphic number B-1-b means that A-1-a, B-1-c, and B-1-d communicate with the passage b on the first floor of the building B on the floor. The suffixes a, c, and d denote passages.

The data processing section 4A reads the route search processing program recorded on the recording medium 2A and executes the following means.

That is, the data processing section 4A reads out the contents of the graphic connection information file 31 shown in FIG. 9 and displays it on the display section 8 through the display control section 9, and designates the current position graphic number from the display contents. Figure designating means 32
A graphic color change display means 33 for color changing and displaying a graphic number designated by the designating means 32 and one or more connected graphics corresponding to the graphic number; and a color change display by the graphic color changing display means 33. One or more connected figures are confirmed, one connected figure (which is also a figure number) relatively close to the destination is designated from among these connected figures, and a figure number which is a new connected figure and this figure number And a destination route searching means 34 for searching for a route to a destination (exit or the like) by changing the color of the connection graphic corresponding to.

According to the above configuration, if the figure number of the current location is "B-1-b", the "B-1-b" is designated and the figure number "B-1-b" is assigned. The connection figure "A-1-
"a", "B-1-c", and "B-1-d" are displayed in different colors.

In this state, for example, when going to the exit, these connection figures "A-1-a" and "B-1-
c "and" B-1-d ", the connection figure" A-1-a "or" B-1-
d "can be found.

Therefore, if these connection figures "A-1-a" or "B-1-d" are designated, the corresponding figure number "A-
If the area corresponding to “1-a” or “B-1-d” is displayed in a different color, the connection figure “A-1-
The route "out" or "B-1-exit" can be searched.

Therefore, according to the above-described embodiment, the graphic connection information file 31 representing the connection graphic of each floor passage is created, and by referring to the graphic connection information file 31, the target location can be easily determined from the current location. The route to the ground can be searched and displayed.

(Fourth Embodiment) This embodiment is similar to the fourth embodiment.
Either or both of the graphic distance and the impassable flag are added to the graphic connection information file 31 shown in FIG. 8 to calculate the shortest distance from the current location to the destination, or to specify the impassable path in the route to the destination. This is an example of searching for the next shortest route excluding that route if there is.

FIG. 10 is a block diagram showing an embodiment of a drawing management system according to the present invention.

Since this drawing management system has basically the same configuration as that shown in FIGS. 2 and 8, the same parts are denoted by the same reference numerals, and the description thereof will be omitted. Hereinafter, particularly different parts will be described.

A particularly different part of this system is that
A shortest path search information file 41, a recording medium 2B storing a shortest distance search program, and a data processing unit 4B for executing a predetermined process based on the shortest distance search program recorded on the storage medium 2B are provided. is there.

As shown in FIG. 11, the shortest route search information file 41 includes the graphic connection information file 3 shown in FIG.
The figure distance (passage distance) and the impassable flag are added to the file item 1 so that the total distance from the current position to the destination can be calculated. Further, the impossible path is searched, and the next shortest path is excluded excluding the path. To provide. It should be noted that when “0” is set as the non-passage flag, it is possible to pass, and when “1” is set, it is not possible to pass the route.

The data processing section 4B is constituted by a CPU, reads a shortest distance search program recorded on the recording medium 2B, and executes a series of processing as shown in FIG. 12 or FIG.

That is, when the data processing unit 4B receives the input current location and destination information, the data processing unit 4B refers to the shortest route search information file 41 and calculates the total distance of some candidate routes. While the route distance calculating means 42 and the number of candidate routes and the order data of the routes are set in the buffer memory 6, the cumulative distances of the candidate routes are compared to determine the shortest route, the next shortest route,. The shortest route determination display means 43 for displaying is provided,
Alternatively, when the non-passage flag is used, in addition to the route distance calculation unit 42 and the shortest route determination display unit 43, when the non-passage flag is set in the shortest route, the next shortest route without the non-passage flag is set. A traversable route selection display means 44 for selecting and displaying is provided.

Next, the operation of the system configured as described above will be described.

(A) Search for the shortest route (FIG. 12)
reference).

When the operation of searching for the shortest path is started, the data processing section 4B clears unnecessary data in the memories 6 and 7 and reads the shortest distance search program from the recording medium 2 and stores it in, for example, the buffer memory 6 or the like. After performing the temporary storage initialization process (S41), it is determined whether or not the current position information and the destination information are input by the input device 1 or the cursor designation of a certain point of the floor drawing currently displayed (S42). . Here, when the current location information and the destination information are input, some candidate routes from the current location to the destination are found by referring to the shortest route search information file 41, and the number of candidate routes and the order data of the routes are buffered. While being set in the memory 6, the total distance of each route is calculated (S43, route distance calculation function).

Specifically, when there is an input with the passage f in the floor plan (4) as the current location and any one of the exits as the destination, the graphic number B-2-f as the current location is changed. From the figure number B-2-f to the connection figure B-1
-E is selected, a connection figure B-1-c is selected from the figure numbers B-1-e corresponding to the connection figure B-1-e, and a figure number B corresponding to the connection figure B-1-c is selected. By selecting a connection graphic B-1-d from -1-c and a connection graphic B-1-exit from a graphic number B-1-d corresponding to the connection graphic B-1-d, one candidate route is selected. figure out.

Also, from the figure number B-2-f of the current location,
Since the candidate route of the exit A on the first floor of the building A and the candidate route of the exit C on the first floor of the building C can be found,
The distances of the paths and stairs of these candidate routes are integrated, and the cumulative distance of each candidate route is calculated.

After the cumulative distances of the candidate routes are calculated as described above, the cumulative distances of the routes are compared, the shortest distance route, the next shortest distance route, the shortest one after another, and so on are determined. After saving in the buffer memory 6
Is set in the counter area of (1), and the shortest path is displayed (S44 to S46, shortest path determination function). The shortest route is displayed by, for example, passage f → stair e → pass c → pass d → exit B or passage f → stair e → pass c → pass d → exit B = total distance ×× m or building name and floor. It may be displayed in the form of a passage that includes it.

In this state, if there is an instruction to select the next shortest route (S47), the counter is incremented by +1 (S48), and the process returns to step S46 to similarly display the next shortest route. If there is an instruction to end the display, the display of the shortest route is ended (S49).

(B) A case where a non-passageable flag is set in a part of the route (see FIG. 13).

If there is a portion that cannot be passed in any of the routes, the non-passable flag “1” is set in the flag area of the shortest route search information file 41.

In this state, the same processing is executed in steps S41 to S45 shown in FIG.

After the shortest route is determined as described above, it is determined whether or not a no-passage flag is set in the shortest route. If the no-passage flag is set, the counter is incremented by +1. , It is determined whether there is a next shortest path. If there is a next shortest route, it is similarly determined whether or not there is a no-passage flag. If there is no no-passage flag, the next shortest route is determined as the shortest route and displayed as described above (S5).
1 to S54, passable route selection display function).

Specifically, for example, a fire or the like occurs in the vicinity of the passage c, and the impossibility flag “1” is set in the flag area corresponding to the graphic number B-1-c belonging to the passage c (see FIG. 11). ).

In this case, all the routes of the connection graphic belonging to the graphic number B-1-c are not allowed to pass, so that the shortest route among the candidate routes, the path f → the stairs e → the path c →
Passage d → Exit B is removed, and instead the next route from other candidate routes, ie, passage f → passage m → staircase k → passage i →
The passage h → the exit C is displayed as the shortest route.

Therefore, according to the above-described embodiment, by setting a route distance (graphic distance) and a pass / fail flag in the shortest route search information file 41 in addition to the graphic number and the connected graphic, By referring to this file, the shortest route of the destination can be searched and displayed from the current location or a certain point, and the shortest route can be searched and displayed while excluding the non-passable route.
