Description

  The present invention relates to an information processing apparatus and method, a program, and a recording medium. In particular, the direction of a component such as a duct can be determined during drawing and editing using an application such as CAD (Computer Aided Design). The present invention relates to an information processing apparatus and method, a computer-executable program, and a computer-readable recording medium on which the program is recorded.

  When drawing a duct using a CAD application according to a conventional example, a main pipe (hereinafter referred to as a main pipe) is usually drawn, and then a branch pipe (hereinafter referred to as a branch pipe) is drawn. In many cases, drawing is done by the procedure, but there are parts with the direction (orientation) in which the air flows, such as 2-way branches, 3-way branches, straight pipes (hereinafter referred to as branch parts), etc., at the branches. The branch parts are drawn in the same direction along the direction in which the main pipe is drawn.

  For example, Patent Document 1 discloses the following configuration in order to provide a pipeline routing method capable of easily and efficiently routing pipelines. When routing is performed from the start point of the pipeline, the start point of the pipeline is specified, and the pipeline attributes such as the type, size, and level of the pipeline are acquired from the initial value master file. When routing is performed from the middle of the pipeline, the previous fixed position is set as the routing start point, and the attribute of the previous fixed position is used. Next, an instruction point indicated by the cursor is acquired following the movement of the cursor. Then, a component connection pattern is selected based on the routing start point and the indication point, a component corresponding to the component connection pattern is selected, and a rubber display (temporary display) is performed between the routing start point and the indication point. . Thereafter, when a designated point is input, the component is fixedly displayed between the routing start point and the designated point.

Japanese Patent Laid-Open No. 10-154165.

  In the case of drawing a duct using the CAD application according to the above-described conventional example, as described above, the branch parts are drawn in the same direction along the direction in which the main pipe is drawn. Since it has a probability of approximately ½ whether or not it faces in the correct direction when drawing, it has been troublesome because the direction of approximately half of the branch parts must be changed.

  FIG. 1 is a block diagram showing a configuration of a drawing data processing apparatus 10 according to an embodiment of the present invention. The drawing data processing apparatus 10 of FIG. 1 is composed of, for example, a digital computer which is an information processing apparatus.

By performing the duct direction determining process of FIG. 9 or the duct direction determining process at the time of changing the diameter in FIGS. 9 to 12, the duct direction in the drawing data is automatically determined and plotted.

  Specifically, at the time of drawing a duct, the orientation is automatically determined by comparing the sizes of the respective diameters at the time of drawing a branch pipe of the duct. Here, whether it is blowing or sucking, the location where the diameter of the branch part should be the largest is generally determined, so that the pipe having the largest diameter is connected to the place where the diameter of the branch part should be the largest. By changing the direction and parts, the direction of the branch parts can be automatically determined. Also, if both sides of the main pipe have the same caliber, such as a straight pipe with a dong, it is determined whether the pipe itself is a main pipe or a branch pipe by following the connection on both sides and observing changes in the caliber and how to connect them. This makes it possible to determine the direction of the straight pipe.

  Similarly, when editing a duct, when the diameter of the duct is changed, it is generally determined where the diameter of the branched part should be the largest, whether it is blown or sucked. The direction of the branch part can be automatically determined by changing the direction and the part so that the pipe having the largest diameter is connected to the part where the diameter of the branch part should be the largest. Here, if both sides of the main pipe have the same caliber, such as a straight pipe with a dong, it is determined whether the pipe itself is a main pipe or a branch pipe by following the connection on both sides and observing changes in the caliber and how to connect them. By doing so, you can determine the direction of donation.

  Hereinafter, an outline of operation and an example when the duct direction determining process at the time of drawing in FIGS. 5 to 8 and the duct direction determining process at the time of changing the diameter in FIGS. 9 to 12 will be described.

  When drawing a route with respect to drawing data, the target part that determines the duct direction when drawing a duct is a so-called “square duct”, which is a bifurcation (for example, two-way branch (straight), two-way branch (both), three-way). Branch), straight pipe with don. In the operation when a branch occurs during drawing, when a branch part is generated, the connection point having the largest diameter regardless of the flow is defined as the connection point P0 (the connection point on the inlet side or upstream side) as in the following embodiments. )) So that the orientation of each other's parts is matched.

<Example 1> FIG. 13A shows a case where a branch pipe (two-way branch 82) is drawn from the main pipe (hopper 81). In FIG. 13A, when the two-way branch 82 is drawn from the hopper 81 in the downward direction 81a, the duct direction is determined and drawn as shown.

<Embodiment 2> FIG. 13B shows a case where a main pipe (two-way branch 83) is drawn from a connection destination (hopper 81). In FIG. 13B, when the two-way branch 83 is drawn from the hopper 81 in the downward direction 81a, the duct direction is determined and drawn as shown.

In the duct direction determination process at the time of drawing, specifically, when there are a plurality of connection points having the largest diameter, in order to determine the connection point P0 of the branch part, the connection destination of the connection point is determined until the following condition is satisfied. Follow and search. Note that even if a branch pipe exists in the connected component, only the main pipe direction is searched, and the branch pipe is not searched.
(Condition 1) When there is a connection point having a diameter larger than the largest diameter (step S27 in FIG. 6).
(Condition 2) When there is a connection point having a smaller diameter than the largest diameter (step S28 in FIG. 6).
(Condition 3) When connected to a branch pipe (other than the connection points P0 and P1) (step S20 in FIG. 5).
(Condition 4) When there is no connected component (step S23 in FIG. 5).
(Condition 5) A case where a hit has already been found (step S21 in FIG. 5).

  In the case of the above conditions 1 and 3), the connection point of the search source is the connection point P0, and the search is terminated without searching for other connection points. In the case of the above conditions 2, 4 and 5, the next connection point is searched. All the connection points are searched, and when the conditions 1 and 3 are not found, the connection point P0 is determined in the priority order of the conditions 4, 5 and 2. If there are multiple cases, the same drawing result as before will be used. If the connection point P0 cannot be determined even after searching to the end, the conventional drawing is performed.

Next, an operation in the case where a donning occurs in the drawing will be described below. A specific example is shown as Example 3.
<Embodiment 3> FIG. 14 shows a case in which a branch pipe (don straight pipe 85) is drawn from the main pipe (straight pipe 84). In FIG. 14, when drawing the dong straight pipe 85 from the straight pipe 84 in the downward direction 84a, the flange 85a is in a direction opposite to the direction in which the diameter of the flange 85a of the dong straight pipe 85 decreases. The duct direction is determined so that it faces. When donning occurs at the time of drawing, duct direction determination processing is performed as follows.

A straight pipe with a dong is generated only when a branch pipe is pulled out from the straight pipe, but the main pipe of the straight pipe with a dong is a straight pipe at the connection destination and has a single caliber. Follow the connection destination of the connection point until the following conditions are satisfied. Note that even if a branch pipe exists in the connected component, only the main pipe direction is searched, and the branch pipe is not searched.
(Condition 11) When there is a connection point having a diameter larger than the diameter of the straight pipe with the dong (step S52 in FIG. 7).
(Condition 12) When there is a connection point having a smaller diameter than the diameter of the straight pipe with the dong (step S53 in FIG. 7).
(Condition 13) When connected to a branch pipe (other than the connection points P0 and P1) (step S45 in FIG. 7).
(Condition 14) When there is no connected part (including a case where the terminal cannot be connected and cannot be searched continuously) (step S46 in FIG. 7).
(Condition 15) A case where a hit has already been found (step S48 in FIG. 7).

  In the case of the above conditions 11 and 13, the dongle head is directed toward the connection point of the search source, and the search is terminated without searching for other connection points. Further, in the case of the above condition 12, the dongle head is directed toward the connection point opposite to the connection point of the search source, and the search is terminated without searching for other connection points. Further, in the case of the above condition 14 and condition 15, the next connection point is searched. If the connection point P0 cannot be determined even after searching to the end, the conventional drawing is performed.

Further, the operation in the case where an existing donation exists in the route will be described below.
<Embodiment 4> FIG. 15 shows a case in which branch pipes (straight pipes 96, 97, 98) are drawn from a main pipe (straight pipes 86, 87, 88). In FIG. 15, when the straight pipes 96, 97, 98 are drawn from the straight pipes 86, 87, 88, respectively, as shown in the drawing, all the flanges 96a, 97a, 98a having the connection relation have the diameters. Drawing is done by determining the duct direction so that it faces in the direction of increasing. That is, when an existing donning is present in the route, the duct direction determination process is performed as follows.

In addition to donning or branching for drawing out a branch pipe from a straight pipe, in order to determine the direction of donning in connection relations, the connection point of the connection point is searched until the following condition is satisfied. If there is a branch pipe in the connection destination component, the branch pipe is also searched.
(Condition 21) When there is no connected part (including a case where the terminal cannot be connected and cannot be searched continuously) (step S64 in FIG. 8).
(Condition 22) A case where a hit has already been found (step S65 in FIG. 8).
Note that the method for determining the direction of each donated brim is the same as described above.

  Next, an example of processing at the time of drawing will be described below. Here, the data contents of the orientation and connection point information (connection destination ID, connection destination connection point, diameter) held by each component are as shown in the duct component data table 23b of FIG. The state is as shown in FIG.

<Processing Example 1> In the case where the donning is pulled out from the straight pipe, specifically, the processing example of the operation when the branch pipe of the duct straight pipe ID8 in FIG. 4 is drawn is as follows. In step S11, the donating straight pipe ID3 is donated (YES in step S11), and in steps S41 to S52, the parts are connected in the order of component ID2, ID1, ID4 connected to the donating straight pipe ID3. A search is performed, and YES is determined in step S53 for hopper ID4, and in step S54, the duct part data table 23b is updated so that the direction of the brim head is directed in the direction of the duct straight pipe ID2. Then, in step S3, a “don add search process” is executed. In this case, it is searched that there is no other don add straight pipe, and the process ends.

In step S12, a two-way branch ID6 is generated between the duct straight pipe ID5 and the duct straight pipe ID7 (YES in step S12). In step S13, the diameters of the connection points P0, P1, and P2 of the two-way branch ID6 are acquired. Then, the size of the aperture (for example, the area of the aperture) acquired in step S14 is calculated. In step S15, the straight pipe side of the duct straight pipe ID5 is determined to have the largest diameter, and in step S32, the two-way branch direction is directed to the straight pipe side of the duct straight pipe ID5, and the connection point 0 of the two-way branch is set to the straight pipe side. Connect to tube ID5. Further, in steps S61 to S69, the straight pipe ID3 is detected and stored in the temporary list table 22a. In step S70, the donation straight pipe ID3 is set as a search target, and the “donation search process” in step S3 is executed. In this case, it is searched that there is no other straight pipe with a don. Then, the “donating direction process” of step S2 is executed for the straight pipe ID3 detected in steps S71 to S72. Further, in steps S41 to S53, search is performed in the order of component ID2, ID1, and ID4 connected to the straight pipe ID3, and the hopper ID4 is set to YES in step S53, and the corresponding is searched. In step S54, the duct part data table 23b is updated so that the direction of the flange with the donation is directed in the direction of the duct straight pipe ID2, and the process ends.

  When editing the duct with respect to the drawing data, the target part that determines the duct direction when the diameter is changed is a so-called “square duct”, which is a bifurcation (for example, two-way branch (straight), two-way branch (both), two-way) Branch (right upright), 2-way branch (left-upright), 2-way branch (right-handed), 2-way branch (left-handed), 3-way branch), and straight pipe with don. In the common operation of changing the diameter of branch parts during duct editing, when the diameter change occurs, the connection point having the largest diameter regardless of the flow is connected to the connection point P0 (connection on the inlet side or upstream side) as in the following example. Point to the same direction).

<Example 5> FIG. 16A shows a case where the diameter of the branch pipe of the two-way branch 91 (straight curve) is changed (150 × 150 → 500 × 300). In FIG. 16A, when the diameter of the two-way branch 91 is changed to the two-way branch 91A, the duct direction is determined and plotted as illustrated.

<Example 6> FIG. 16B shows a case where the diameter of the main pipe of the two-way branch 92 (both music) is changed (500 × 300 → 150 × 150). In FIG. 16B, when the diameter of the two-way branch 92 is changed to the two-way branch 92A, the duct direction is determined and plotted as shown.

In the duct direction determination process at the time of editing the diameter change, specifically, when there are a plurality of connection points having the largest diameter, the connection point P0 is determined until the following condition is satisfied in order to determine the connection point P0 of the branch part. Search by following the connection destination. Note that even if a branch pipe exists in the connected component, only the main pipe direction is searched, and the branch pipe is not searched.
(Condition 1) When there is a connection point having a diameter larger than the largest diameter (step S52 in FIG. 7).
(Condition 2) When there is a connection point having a smaller diameter than the largest diameter (step S53 in FIG. 7).

(Condition 4) When there is no connected component (step S48 in FIG. 7).
(Condition 5) When hitting a component already searched (step S46 in FIG. 7).

  In the case of the above conditions 1 and 3, the connection point of the search source is the connection point P0, and the search is terminated without searching for other connection points. In the case of the above conditions 2, 4 and 5, the next connection point is searched. When all the connection points are searched and the above condition 1 and condition 3 are not found, the connection point 0 is determined in the priority order of the above condition 4, condition 5 and condition 2. If there are multiple cases, the same drawing result as before will be used. If the connection point 0 cannot be determined even after searching to the end, the conventional drawing is performed.

Next, the operation in the case where the diameter change of the straight pipe with a don occurs at the time of editing will be described below. A specific example is shown as Example 7.

To do.

When the diameter of a straight pipe with a dong is changed during editing, duct direction determination processing is performed as follows. That is, when the diameter of the main pipe is changed by changing the diameter of the straight pipe with the dong, in order to determine the connection point P0 of the straight pipe with the dong, the connection point of the connection point is searched until the following condition is satisfied. Note that even if a branch pipe exists in the connected component, only the main pipe direction is searched, and the branch pipe is not searched.

(Condition 15) When hitting a component already searched (step S46 in FIG. 11).

  In the case of the above conditions 11 and 13, the dongle head is directed toward the connection point of the search source, and the search is terminated without searching for other connection points. Further, in the case of the above condition 12, the dongle head is directed toward the connection point opposite to the connection point of the search source, and the search is terminated without searching for other connection points. Further, in the case of the above condition 14 and condition 15, the next connection point is searched. If the connection point P0 cannot be determined even after searching to the end, the conventional drawing is performed.

Drawing is performed by determining the duct direction so that is oriented in the direction in which the diameter increases.

In addition to donning or branching for drawing out a branch pipe from a straight pipe, in order to determine the direction of donning in connection relations, the connection point of the connection point is searched until the following condition is satisfied. If there is a branch pipe in the connection destination component, the branch pipe is also searched.

In step S12A, the diameter of the two-way branch ID 6 is changed. In step S13A, the respective diameters of the connection points P0, P1, and P2 of the two-way branch ID 6 are acquired. In step S14, the diameter (for example, the diameter of the diameter) is acquired. Area). In step S15, the duct straight pipe ID5 side is determined to have the largest diameter, and in step S32, the direction of the two-way branch is directed to the straight pipe ID5 side, and the connection point P0 of the two-way branch is connected to the duct straight pipe ID5. Further, in step S61-69, the donated straight pipe ID3 is detected and stored in the temporary list table 22a. In step S70, the donation straight pipe ID3 is set as a search target, and the “donation search process” in step S3A is executed. In this case, it is detected that there is no other straight pipe. In step S2A, “donating direction processing” is performed on the straight pipe ID3 detected in steps S71 to S72. Then, in steps S41 to S53, the parts ID2, ID1, and ID4 connected to the donated straight pipe ID3 are searched in the order of steps, and the hopper ID4 becomes YES in step S53, and in step S54, the donating is performed in the direction of the duct straight pipe ID2. The duct part data table 23b is updated so that the direction of the brim is directed, and the process ends.
