Field of the Invention The present invention relates to a layout design method of disaster prevention equipment for arranging symbols of disaster prevention equipment such as a fire detector on a plan view displayed on a display in a CAD system or the like, and to a computer using the method. The present invention relates to a recording medium storing a layout design program for disaster prevention equipment to be executed.

[0002]

2. Description of the Related Art Conventionally, CAD equipment has been used for designing disaster prevention equipment for buildings and the like. A symbol of the disaster prevention equipment is arranged on a display, and a wire is drawn between the symbols by operating a mouse or the like. We have completed the design drawing. Of these, in the layout design of disaster prevention equipment, the number of disaster prevention equipment to be placed in the room is calculated by inputting the floor area of the room where the disaster prevention equipment is placed, the type of the disaster prevention equipment, and the height of the mounting surface. The calculated number of disaster prevention devices are manually placed on the plan view.

[0003]

However, in the above-mentioned conventional layout design method of the disaster prevention equipment, the arrangement of the disaster prevention equipment is performed manually, which is inefficient. Further, such an arrangement design is performed based on the ability of a designer, and there is a problem that only a person having design knowledge can perform the layout design.

[0004] The present invention has been developed in view of such circumstances, and is intended to provide a layout design method for disaster prevention equipment that enables efficient design of the layout of disaster prevention equipment, and to allow a computer to execute the method. It is an object of the present invention to provide a recording medium in which a layout design program for disaster prevention equipment is recorded.

[0005]

In order to achieve the above object, claims 1 to 8 propose a new method of designing the arrangement of disaster prevention equipment on a plan view of a building displayed on a display. ing. According to claim 1, when the shape of the room in which the disaster prevention equipment is arranged is specified and the number of arrangements of the disaster prevention equipment is input, a shape simplification process for simplifying the room shape,
A room shape pattern search process for searching for a pattern that matches a simplified room shape from room shape patterns registered in advance, and a plurality of disaster prevention devices registered in advance corresponding to the room shape pattern and the number of arranged disaster prevention devices A layout pattern determining process for determining a layout pattern of a plurality of disaster prevention devices corresponding to a simplified room shape from a reference layout pattern of

The arrangement patterns of the disaster prevention devices are displayed on the display in descending order of priority, and the arrangement determination processing for determining the arrangement of the disaster prevention devices is sequentially executed.

[0006] This method is suitably used by a computer (such as a CAD device), and specifies the shape of a room in which disaster prevention equipment is to be placed, the designation of a room name, and the range of a room with a mouse at multiple points. If you specify the number and input the number of arrangements, the disaster prevention equipment is automatically arranged. The number of arrangements may be automatically calculated from the room area and input.

[0007] Claim 2 proposes the shape simplification processing of claim 1, wherein, among the sides of the polygon forming the room shape, a process of changing a predetermined plurality of adjacent sides to one side, And changing at least one of the processes of changing the angle of one side to a predetermined angle and changing the length of the one side in accordance with the direction of the adjacent side.

[0008] Claim 3 proposes the room shape pattern search processing of claim 1 and matches a simplified room shape from rotation, line symmetry and point symmetry of the room shape pattern registered in advance. And a process of searching for a pattern to be performed. In the room shape pattern search process, a simplified room shape is searched from room shape patterns such as a rectangle, an L-shape, a concave shape, and a convex shape. Is also searched. Here, rotation refers to rotation to a predetermined angle around an arbitrary point, and line symmetry refers to symmetry about an arbitrary straight line as a center line, and point symmetry refers to rotation about an arbitrary point as a center. It means making it symmetrical as a point.

Claims 4 to 6 propose the arrangement pattern determination processing of claim 1. In claim 4, based on a room shape division pattern registered in advance corresponding to the reference arrangement pattern, The simplified room shape is divided, and an arrangement pattern of a plurality of disaster prevention devices corresponding to each of the divided shapes is determined. Here, if a pattern for dividing one room shape into two or more rectangular shapes is registered as a room shape division pattern, an arrangement pattern of disaster prevention devices can be easily determined.

According to a fifth aspect of the present invention, the arrangement pattern determining process includes:
Assuming that the simplified room shape is a rectangular shape, in advance, from a rectangular room shape pattern and a reference arrangement pattern of a plurality of disaster prevention devices registered corresponding to the number of arranged disaster prevention devices,
An arrangement pattern of a plurality of disaster prevention devices corresponding to a simplified room shape is determined. In claim 6, the arrangement pattern determination processing assumes that the simplified room shape is a resimplified room shape, and a plurality of disaster prevention devices registered in advance corresponding to the room shape pattern and the number of disaster prevention devices arranged. From the reference layout pattern, determine the layout pattern of a plurality of disaster prevention devices corresponding to the re-simplified room shape, and further arrange the plurality of disaster prevention devices corresponding to the simplified room shape from the determined layout patterns. Determine the pattern.

Further, in claim 7, claims 1 and 4

[0014]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a flowchart illustrating a method for designing the layout of disaster prevention equipment according to the present invention. This method is suitably used by a personal computer (such as a CAD device), and designs an arrangement of disaster prevention equipment on a plan view of a building displayed on a display.

First, the shape of the room in which the disaster prevention equipment is arranged is specified, and the number of arrangements of the disaster prevention equipment is input (arrangement area / arrangement number input processing). As the shape of the room, a polygonal area is specified by a mouse multipoint instruction or the like. At this time, a rectangular shape may be designated by diagonal designation (block designation). The number of disaster prevention devices to be arranged may be obtained by obtaining a room area of a designated shape and automatically calculating the room area.

Next, the designated room shape is simplified (shape simplification processing). That is, the corners of a polygon having many corners are reduced, and each corner is made a right angle. Therefore, when the room shape is a rectangular shape, there is no need for simplification. Then, from the room shape patterns registered in the pattern / division method knowledge base in advance, a pattern that matches the simplified room shape is searched (deformation and pattern matching processing (room shape pattern search processing)). Here, the room shape includes a rectangle, an L-shape, a concave shape, a convex shape, and the like, and can also include a shape obtained by rotating these shapes, and a shape symmetrical with a point and symmetric.

Next, based on the room shape pattern registered in advance in the pattern / division method knowledge base and the reference arrangement pattern of a plurality of disaster prevention devices registered corresponding to the number of arranged disaster prevention devices, a simplified room shape Is determined (division arrangement combination generation processing (arrangement pattern determination processing)). A priority is determined based on the determined arrangement pattern of the plurality of disaster prevention devices based on a predetermined criterion registered in the superior arrangement determination knowledge base (priority sort processing (priority determination processing)). Then, the arrangement pattern of the disaster prevention devices is displayed on the display in the descending order of the priority, and the arrangement of the disaster prevention devices is determined (location determination processing).

In this case, if the room shape is deformed for pattern matching in the deformation and pattern matching processing after executing the superior order sorting processing, the arrangement coordinates of the disaster prevention equipment are changed.
Arrangement coordinate transformation processing). Finally, the arrangement coordinates are collected and registered as a coordinate list in association with the plan view (arrangement coordinate set processing).

As described above, according to the method of the present invention, the shape of the room in which the disaster prevention equipment is arranged is designated by a multi-point instruction of the mouse or the like, and the number of arrangements is input, thereby automatically disposing the disaster prevention equipment. be able to. Next, each process described above will be described. In the plan view of the building displayed on the display, the area where the disaster prevention equipment is to be arranged is indicated at multiple points (click operation) with a mouse or the like, and when the number of arrangements is input, the shape simplification processing is performed. FIG. 2 shows the shape simplification process.
5 will be described together with FIG.

In order to code a room shape, first, an arbitrary vertex of a polygon forming the room shape is set as a starting point. Then, turn in any direction from the start point (FIG. 2).
(B) turns counterclockwise), and gives each side a direction (vectorization). Then, each side is coded in order from the start point according to the direction code shown in FIG. If the direction of the side is in a range separated by a dotted line centered on each direction code in FIG. 2A, the direction code is assumed to be the center code. For example, as shown in FIG. 2B, when coding is performed with each side having a direction, the code list is as shown in FIG.
The result is as shown in FIG. With this coding, the room shape can be simplified.

In FIG. 2A, the direction codes are set to eight directions, but the present invention is not limited to this. However, if the number of direction codes is increased, the number of room-shaped patterns to be described later increases, and the processing becomes complicated. Therefore, it is preferable to use eight directions. Further, when encoding, among the respective sides of the polygon constituting the room shape, a process of changing a predetermined plurality of adjacent sides to one side, while changing the angle of the predetermined one side to a predetermined angle, At least one of the processes for changing the length of one side in accordance with the direction of the adjacent side can be included and executed.

FIGS. 3 and 4 show an example of processing for changing a plurality of predetermined adjacent sides to one side. Here, each vertex of the polygon forming the room shape is represented by coordinates, and a coordinate list is shown together with a code list.
If the directions of the direction codes “0” and “4” shown in FIG. 2A are the X axis and the directions of the direction codes “2” and “6” are the Y axis, the coordinates are (X, Y). expressed. If processing is performed so as to reduce the number of coordinates represented in this way, the number of sides can be reduced.

In FIG. 3A, in the code list,
Since the element “0” is continuous, the continuous elements are combined into one, a list as shown in FIG. 3B is created, and two sides are changed to one side. Further, in FIG. 4A, in the code list, the length of the element “6” sandwiched by the same element “0” is equal to or less than a predetermined length (here, the length is “5”). , Removing this element, FIG.
A list as shown in (b) is created, and three sides are changed to one side.

When referring to the code list, it is necessary to refer to the last element and the first element as being continuous. FIG. 5 illustrates an example of a process of changing the angle of a predetermined side to a predetermined angle and changing the length of the side according to the direction of an adjacent side. The side represented by the direction and the coordinates as shown in FIG. 11A is changed to the side as shown in FIGS. 11B, 11C and 11D.

Here, a case where the side whose direction code is in the range of "2" (see FIG. 2A) is changed is shown.
After making the direction of the side coincide with the direction of the code “2”, the X coordinate of the coordinates at both ends of the side is changed to the average value of both X coordinates. Then, a difference from the original coordinates to the average value is obtained. If the direction code of the adjacent side is “0” or “4” as shown in FIG. If the direction code of the adjacent side is “1”, the Y coordinate is shifted in the direction of the code “2” by the difference as described above and the direction code of the adjacent side is “5” as shown in FIG. If there is, the Y coordinate is moved by the difference in the code “6” direction. If the direction code of the adjacent side is “3”, the Y coordinate is shifted by the difference in the code “6” direction as shown in FIG. If so, the Y coordinate is moved by the difference in the code “2” direction.

Here, only an example is shown.
Change to the side of other direction code or direction code "2"
Is not limited to this example. Next, along with FIGS. 6 to 8, a deformation and pattern matching process (room shape pattern search process)
Will be described.

Here, a pattern that matches the shape subjected to the shape simplification processing is searched from a plurality of room shape patterns registered in advance. In FIG. 6, the code list (FIG. 2C) is searched. Based on this, we are searching for room shape patterns. Here, a case where the simplified room shape shown in FIG. 6A is the L-shaped shape shown in FIG. 6C is shown. Note that the room shape pattern includes a rectangular shape shown in (b), a convex shape shown in (d), a concave shape, and the like.

On the other hand, as shown in FIG. 7A, when the room shape patterns do not match based on the code list, as shown in FIGS. (Shown by white circles) so that both code lists match. Further, in the deformation and pattern matching processing, the rotation, line symmetry, and point symmetry patterns of the room shape pattern are registered in advance in the pattern / division method knowledge base, and from these, the room shape pattern matches the simplified room shape. You can also search for patterns.

Note that, instead of the room shape pattern, a simplified room shape may be transformed by rotation, line symmetry, and point symmetry. FIG. 8 shows such a case. FIG.
(A) is the original shape, (b) is a shape rotated 90 degrees counterclockwise, (c) is a shape symmetric with respect to the Y axis, and (d) is a shape symmetric with respect to the origin point. In addition, the deformation includes 18
0 degree rotation, 270 degree rotation, X axis line symmetry, Y = X linear symmetry, Y = −X linear symmetry, and the like are also included.

As described above, when the room shape is deformed, even if the room shape pattern does not match before the deformation, the probability that the room shape pattern will match after the deformation is increased. Then, when the room shape is rotated or the like, the arrangement coordinate transformation process is required to finally restore the coordinate list of the disaster prevention equipment to be arranged. Next, the split arrangement combination generation processing (arrangement pattern determination processing) will be described with reference to FIGS.

Here, the arrangement pattern of a plurality of disaster prevention devices corresponding to the simplified room shape is determined from the reference arrangement pattern of the plurality of disaster prevention devices registered in advance in accordance with the room shape pattern and the number of arrangements of the disaster prevention devices. decide. FIG.
An example in which one disaster prevention device is arranged is shown. As shown in (a), there are a plurality of reference arrangement patterns (shown by white circles in the figure) for the room shape of the L-shaped pattern. When applied to a simplified room shape that matches the character pattern, a plurality of arrangement patterns are determined as shown in (c).

Further, the division arrangement combination generation processing includes:
If the number of disaster prevention devices is 2 or more (multiple),
The simplified room shape is divided based on the room shape division pattern registered in advance in the pattern / division method knowledge base corresponding to the reference arrangement pattern, and a plurality of disaster prevention devices corresponding to each of the divided shapes. Can be determined.

FIGS. 10A and 10B show examples of such a case. FIG. 10A shows an example of a divided pattern, and FIG. 10B shows an example in which a simplified room shape is divided based on the pattern. In this division pattern, the number of divisions and the like may be changed depending on the number of arrangements of disaster prevention devices. As shown in the figure, if a pattern for dividing one room shape into two or more rectangular shapes is registered as a room shape division pattern, the number of disaster prevention devices to be arranged is allocated to each of the divided shapes. If this is the case, it is easy to determine the arrangement pattern of the disaster prevention equipment.

FIG. 11 shows an example of an arrangement pattern of a plurality of disaster prevention devices when the room shape is divided as shown in FIG. 10 (b). FIG. 11A shows a case where three disaster prevention devices are arranged, and FIG. 11B shows a case where four disaster prevention devices are arranged. Here, the arrangement pattern is determined as arranging the three disaster prevention devices input in, but as shown in (b), the number of disaster prevention devices is added by one to simplify the room. An arrangement pattern of a plurality of disaster prevention devices corresponding to the shape is determined. As a result, there is no area in the room that is not monitored (not processed) by the disaster prevention equipment. Note that the arrangement pattern for each of the divided shapes may be such that the disaster prevention equipment is distributed and arranged at an area ratio.

Further, the division arrangement combination generation processing includes:
Assuming that the simplified room shape is a rectangular shape, in advance, from a rectangular room shape pattern and a reference arrangement pattern of a plurality of disaster prevention devices registered corresponding to the number of arranged disaster prevention devices,
An arrangement pattern of a plurality of disaster prevention devices corresponding to a simplified room shape may be determined. FIG. 12 shows an example of this, in which the L-shape shown in (a) is regarded as the rectangular shape of (b) circumscribing the shape, and after disposing the disaster prevention equipment, the shape is changed to the original L-shape. And the disaster prevention equipment deviating from within the shape is excluded from the arrangement pattern ((c)).
reference). At this time, the number of disaster prevention devices only needs to be equal to or more than the number input in.

Further, the division arrangement combination generation processing includes:
Assuming the simplified room shape as the resimplified room shape,
In advance, from the reference arrangement pattern of a plurality of disaster prevention devices registered in accordance with the room shape pattern and the arrangement number of the disaster prevention devices, determine the arrangement pattern of a plurality of disaster prevention devices corresponding to the re-simplified room shape, further, From the plurality of arrangement patterns, an arrangement pattern of a plurality of disaster prevention devices corresponding to a simplified room shape may be determined.

FIG. 13 shows an example in which the simplified shape as shown in FIG. 13A is further simplified into an L-shape as shown in FIG. Also at this time, similarly to the case of FIG. 12, after disposing the disaster prevention equipment in the L-shaped room of (b),
The shape may be returned to the original shape of (a), and the removed disaster prevention device may be removed from the arrangement pattern. Next, the priority order sorting process (priority order determination process) will be described with reference to FIGS.
This will be described with reference to FIG.

In the priority order sorting process, priorities are determined based on a predetermined reference registered in the superior location determination knowledge base based on the arrangement pattern of a plurality of disaster prevention devices determined in the divided arrangement combination generation process. Then, the arrangement patterns of the disaster prevention devices are displayed in the descending order of the priority, and the arrangement of the disaster prevention devices is determined (location determination processing). The priority order sorting process includes, as a predetermined criterion, the number of disaster prevention devices arranged in a simplified room shape (at least, it is necessary to be equal to or more than the input number of arrangements), the area of the monitoring range of each disaster prevention device, The ratio of the area to the total area of the room shape, the distance from each disaster prevention device to the limit of the monitoring range, the area outside the monitoring range of all the disaster prevention devices, the ratio of the area to the total area of the room shape, the average value of each of these -Include at least one of the maximum value, the minimum value, the number of rows and the number of columns of the disaster prevention device.

FIG. 14 shows some of the criteria. FIG. 14A shows one disaster prevention device to be arranged.
The distance from the disaster prevention equipment to each vertex of the polygon forming the room shape is obtained. This makes it possible to determine whether the monitoring range of the disaster prevention device includes the entire range of the room. In this case, among the distances to the vertices, the priority may be determined in ascending order of the longest distance.

FIG. 6B shows the area of the monitoring range of each disaster prevention device when a plurality of disaster prevention devices are arranged. In this case, the average value of each area may be obtained, and the priority may be determined in the order of the smaller average value. FIG. 9C shows a case where a plurality of disaster prevention devices are arranged, and the distance to the farthest position in the monitoring range is obtained for each disaster prevention device. In this case as well, the average value of each distance may be obtained, and the priority order may be determined in ascending order of the average value.

FIG. 4D shows the area (shaded area) outside the monitoring range of all the disaster prevention devices when a plurality of disaster prevention devices are arranged. In this case, the priority may be determined in the order of small (small) area. FIG.
The number of rows and columns of disaster prevention equipment is calculated. The number of arranged rows and the number of arranged digits are, in other words, the number of types of the X coordinate and the Y coordinate of the coordinates where the disaster prevention device is arranged. Here, a case is shown in which both the number of rows and the number of digits are two. In consideration of the wiring between the disaster prevention devices, the priority may be determined in ascending order of these numbers.

FIG. 15 shows an example of the priority order of the wiring patterns determined based on these criteria. Here, there are two criteria: [the average of the maximum values of the distances from each disaster prevention device to each vertex, the number of disaster prevention devices], and the former has a lower priority and the latter has a higher priority. Is high. In the arrangement patterns of (a) and (b) shown, the latter value is the same, but the former value is smaller in (a).
The arrangement pattern of (a) has a higher priority.

Thereafter, the arrangement pattern having the highest priority is automatically displayed on the display. If the pattern is acceptable, the arrangement position is determined. However, when another pattern is good, the pattern with the next highest priority is displayed. As described above, according to the method of the present invention, the layout patterns are displayed in the order of priority, and the layout design of the disaster prevention equipment can be designed according to the preference of the designer.

FIG. 16 shows a plan view of the display.
The example in which the disaster prevention equipment was arranged is shown. Here, in the area indicated by A, the fire detectors S are equally arranged in each of the office room, living room, and hot water room. Here, for the uniform arrangement, the arrangement interval between the plurality of fire detectors S is the same, the distance between the fire detectors S from the wall is the same, and the distance between the fire detectors S and the wall is To make the ratio to the distance the same.

Next, a description will be given of a recording medium on which a program for executing the above-described method for designing the arrangement of disaster prevention equipment is recorded.
