Description

The present invention relates to a data creation device, a data creation method, and a program.

Conventionally, when performing hydraulic analysis or pipe network evaluation for pipe networks such as water and sewage, the pipe network data of the mapping system is utilized. The pipe network data is data showing attributes such as the pipe type, diameter, and laying year of a plurality of pipes constituting the pipe network.

When there is a pipe with unknown attributes in the pipe network data, it is common to supplement the pipe. Complementation is the estimation of the attributes of a tube whose attributes are unknown, based on the attributes of the surrounding tubes whose attributes are known. However, there is no clear rule for complementing the current situation, and the attributes of the pipe are judged with reference to the experience of the planner who complements and similar cases.

However, when the planner performs complementation as described above, the complemented attributes may reflect the planner's personal tendencies. This may cause deviations in the network data complemented by each planner. Further, the attributes of the complemented pipes are verified by the pipe network analysis system, but if the above deviation occurs, the complementation is not appropriate and it is necessary to repeat the complementation again. Furthermore, even if an experienced planner is assigned or a similar case is investigated in order to make appropriate supplements, the labor cost associated with it is high, which is not realistic.

One aspect of the present invention is to realize a data creation device capable of efficiently complementing pipeline attributes.

In order to solve the above problems, the data creation device according to one aspect of the present invention is a data creation device used for analyzing a pipe network, and has attributes among a plurality of pipes constituting the pipe network. Attribute to determine whether to complement the attribute related to the attribute unknown pipe from the attribute of the attribute known pipe that is known about the attribute in the pipe network and the attribute unknown pipe identification part that identifies the pipe of unknown attribute as the attribute unknown pipe. When the complementability determination unit and the attribute complementability determination unit determine that complementation is possible, the attribute complement unit that complements the attribute related to the attribute unknown tube based on the attribute related to the attribute known tube, and the attribute complement unit It is provided with a pipe network attribute data creation unit that creates pipe network attribute data indicating attributes related to a plurality of pipes constituting the pipe network so as to include the complemented attributes of the attribute unknown pipe.

According to one aspect of the present invention, pipeline attributes can be efficiently complemented.

[Embodiment 1]
Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 1 to 7.

(Structure of data creation device 1)
FIG. 1 is a block diagram showing the structure of the data creation device 1. As shown in FIG. 1, the data creation device 1 includes a control unit 2, an input unit 3, and a storage unit 4. In the data creation device 1, in order to analyze the piping network, the input unit 3 acquires the pipe network data, and the control unit 2 complements and creates the piping network attribute data based on the pipe network data, and the created piping. The network data is stored in the storage unit 4.

Here, the pipe network data is data indicating the arrangement of a plurality of pipes constituting a certain pipe network and the attributes related to the pipes, and the pipe network attribute data is the attributes related to the pipes complemented by the control unit 2. It is the data which shows the pipe network data including. In addition, the attributes related to pipes include at least three elements: (1) pipe type, (2) caliber, and (3) laying year.

As shown in FIG. 1, the control unit 2 includes an attribute unknown pipe identification unit 5, an attribute complementability determination unit 6, an attribute complement unit 7, and a piping network attribute data creation unit 8. Further, the control unit 2 acquires the pipe network data from the input unit 3.

The attribute unknown pipe specifying unit 5 identifies a pipe having an unknown attribute among a plurality of pipes constituting the piping network as an attribute unknown pipe based on the pipe network data. In addition, unlike a tube having an unknown attribute, a tube having a known attribute is referred to as a tube with a known attribute. The attribute unknown tube specifying unit 5 outputs the information on the arrangement of the specified attribute unknown tube and the unknown attribute to the attribute complementability determination unit 6.

The attribute complementability determination unit 6 is based on the tube network data, the arrangement of the unknown attribute tube acquired from the attribute unknown tube identification unit 5, and the information of the unknown attribute, from the attribute of the known attribute tube to the attribute related to the unknown attribute tube. Judge whether complementation is possible. Further, the attribute complementability determination unit 6 acquires the piping network attribute data from the piping network attribute data creation unit 8 and determines whether or not the attribute of the unknown attribute pipe in the piping network attribute data can be complemented. The attribute complementability determination unit 6 outputs the determination result relating to the above complementability to the attribute complementation unit 7.

The attribute complementing unit 7 acquires the above-mentioned determination result relating to the complementability from the attribute complementability determination unit 6. When it is determined that the attribute unknown tube can be complemented, the attribute complementing unit 7 refers to the pipe network data and complements the attribute related to the attribute unknown tube based on the attribute related to the attribute known tube. Further, the attribute complementing unit 7 outputs the attributes related to the complemented attribute unknown pipe to the piping network attribute data creating unit 8.

The piping network attribute data creation unit 8 acquires the attributes of the unknown attribute pipe complemented by the attribute complement unit 7 from the attribute complement unit 7. Further, the pipe network attribute data creation unit 8 acquires the pipe network data, creates the pipe network attribute data so that the pipe network data includes the attribute, and outputs the pipe network attribute data to the storage unit 4. Further, when the pipe network attribute data creating unit 8 has an unknown attribute pipe in the created pipe network attribute data, the pipe network attribute data creating unit 8 outputs the piping network attribute data to the attribute complementability determination unit 6.

The input unit 3 acquires the pipe network data from the outside and outputs it to the control unit 2. When acquiring the pipe network data, the input unit 3 may accept the manual input of the attribute data related to the pipe, or may acquire the data stored outside the data creation device 1.

The storage unit 4 is a storage area for acquiring and storing the piping network attribute data from the piping network attribute data creating unit 8. If the pipe with unknown attribute is not complemented, the storage unit 4 acquires the pipe network data from the control unit 2 and stores it as the pipe network attribute data.

(Example of processing flow in data creation device 1)
The process flow of the data creation method in the data creation apparatus 1 according to the first embodiment of the present invention will be described. First, the data creation device 1 acquires the network data in the input unit 3 and outputs it to the control unit 2. Next, the control unit 2 performs each of the following steps in order.
(1) Attribute unknown pipe identification step: The attribute unknown pipe identification unit 5 identifies a pipe with an unknown attribute as an attribute unknown pipe based on the pipe network data.
(2) Attribute completion possibility determination step: The attribute completion possibility determination unit 6 determines whether or not the attribute completion of the above-mentioned attribute unknown tube is possible.

The piping network attribute data created in the piping network attribute data creation step outputs the piping network attribute data to the storage unit 4. Finally, the storage unit 4 stores the acquired piping network attribute data.

(How to supplement the caliber)
Hereinafter, the method of complementing the attributes related to the pipe will be described. First, as an attribute related to the pipe, a complementing method in the case of complementing the diameter will be described with reference to FIGS. 2 and 3. FIG. 2 is a schematic view showing an example of a piping network when pipes are connected in a straight line.

When the diameters of the start point and the end point of a certain attribute unknown pipe are the same, the attribute complementability determination unit 6 determines that the attribute can be complemented, and the attribute complement unit 7 complements the diameter as the diameter of the attribute unknown pipe. Further, when the diameters of the start point and the end point are different, the attribute complementability determination unit 6 determines that the attribute can be complemented, and the attribute complement unit 7 selects the larger diameter of the two diameters as the diameter of the tube of unknown attribute. And complement. Further, when the diameter is acquired for only one of the start point and the end point and the other diameter is not acquired, the attribute complementability determination unit 6 determines that the attribute complement is possible. Further, the attribute complementing unit 7 complements the acquired diameter as the diameter of the tube of unknown attribute. Further, when the diameter is not acquired for both the start point and the end point of the tube of unknown attribute, the attribute complementability determination unit 6 determines that the attribute cannot be complemented for the diameter.

In the above-mentioned method, when the diameters of the start point and the end point of the tube of unknown attribute are different, the larger diameter is selected, but it may be set to select a smaller diameter as a complementary condition.

As shown in FIG. 2, it is assumed that the pipes 10 to 14 are connected in a straight line. Here, a method of complementing the diameter when the pipe 11 is a pipe of unknown attribute and the pipe 10 connected to the start point of the pipe 11 and the pipe 12 connected to the end point of the pipe 11 are pipes of known attributes will be described. do.

For example, assuming that the diameter of the pipe 10 is 100 mm and the diameter of the pipe 12 is 75 mm, the attribute complementing unit 7 selects and complements a large diameter, that is, 100 mm, as the diameter of the pipe 11.

Next, a complement method will be described when the pipes 11 to 13 are pipes of unknown attributes and the pipes 10 and 14 are pipes of known attributes. It is assumed that the diameter of the pipe 10 is 100 mm and the diameter of the pipe 14 is 75 mm. At this time, first, the attribute complementing unit 7 selects 100 mm as the diameter of the pipe 11 and 75 mm as the diameter of the pipe 13 to complement the pipe 11.

Next, the attribute complementability determination unit 6 determines that the attribute complement is possible for the pipe 12 by using the complemented diameters for the pipe 11 and the pipe 13. Then, the attribute complementing unit 7 selects and complements 100 mm, which is a larger diameter among the complemented diameters, as the diameter of the pipe 12.

In this way, even when a plurality of unknown attribute tubes are continuous, when complementation is performed for one unknown attribute tube, the complemented attribute can be used to complement the attribute related to another unknown attribute tube. ..

Next, a method of complementing the diameter when a plurality of pipes are connected to the starting point of a pipe of unknown attribute will be described. As shown in FIG. 3, a plurality of pipes 15 and 16 are connected to the starting point of the pipe 17, the pipe 17 is a pipe of unknown attribute whose diameter is unknown, and the pipes 15 and 16 have a diameter as an attribute. Known attributes Suppose it is a known tube. Further, it is assumed that the diameter of the pipe 15 is 100 mm and the diameter of the pipe 16 is 75 mm.

In this case, for the diameter of the pipe 17, the smaller one of the diameter of the pipe 15 and the diameter of the pipe 16 is selected and complemented with 75 mm.

(How to supplement the laying year)
Next, as an attribute related to the pipe, the complementing method when complementing the laying year will be described. FIG. 4 is a diagram showing complement conditions when complementation is performed for the laying year, and FIG. 5 is a schematic diagram showing an example of a piping network when a plurality of pipes are connected to the start point and the end point of a pipe of unknown attribute. Is.

When complementing the laying year or pipe type, the attribute complementability determination unit 6 acquires the representative values of the start point and the end point of the pipe whose attribute is unknown. Here, the representative value is an attribute unknown in the attribute unknown tube related to the attribute known tube connected to the start point and the end point of the attribute unknown tube. When multiple known attribute tubes are connected to the start point or end point of an unknown attribute tube, the attribute of the known attribute tube that has the most matching elements with the known attribute among the attributes related to the unknown attribute tube is selected as the representative value. Will be done.

The conditions for supplementing the laying year will be described with reference to FIG. If the representative values acquired for the start point and the end point of a certain attribute unknown pipe are the same, the attribute complementability determination unit 6 determines that the attribute can be complemented, and the attribute complement unit 7 determines that the representative value is the laying year of the attribute unknown pipe. Complement as. Further, when the representative values of the start point and the end point are different, the attribute complementability determination unit 6 determines that the attribute complement is possible, and the attribute complement unit 7 determines that the older laying year of the two representative values is the attribute unknown pipe. Select and supplement as the laying year. Further, when the representative value is acquired for only one of the start point and the end point and the other representative value is not acquired, the attribute completion possibility determination unit 6 determines that the attribute can be complemented. Further, the attribute complementing unit 7 complements the acquired representative value as the laying year of the pipe of unknown attribute. Further, when the representative value is not acquired for both the start point and the end point of the tube of unknown attribute, the attribute complementability determination unit 6 determines that the attribute complement cannot be completed for the laying year.

A method of performing attribute complementation for the laying year will be described with reference to FIG. For example, it is known that the laying year of the pipe 11 is unknown, the laying year of the pipe 10 is 1990, and the laying year of the pipe 12 is 1970. In this case, the attribute completion possibility determination unit 6 determines that the attribute completion is possible. Further, the attribute complementing unit 7 selects and complements the older laying year 1970 as the attribute related to the pipe 11.

Next, with reference to FIG. 5, a method of complementing the case where the pipe 21 is an attribute unknown pipe whose laying year is unknown and a plurality of attribute known pipes are connected to the start point and the end point of the pipe 21 will be described. .. As shown in FIG. 5, pipes 18 to 20 are connected to the start point and pipes 22 to 24 are connected to the end point of the pipe 21. Further, the balloon in FIG. 5 shows the attributes related to each pipe.

In performing complementation, the attribute complementability determination unit 6 first acquires representative values of the start point and the end point of the pipe 21. As shown in FIG. 5, the attributes of the pipes 18, 19 and 20 connected to the starting point of the pipe 21 are summarized as follows.
Tube 18-tube type: B, caliber: 50 mm, laying year: β year tube 19-tube type: A, caliber: 100 mm, laying year: 1960 tube 20-tube type: C, caliber: 75 mm, laying year: α Year Here, since the pipe type of the pipe 21 is A and the diameter is 100 mm, the attribute complementability determination unit 6 sets 1960, which is the laying year of the pipe 19 having the same pipe type and diameter as the pipe 21. It is selected as the representative value of the starting point at 21.

Further, as shown in FIG. 5, the attributes of the pipes 22, 23 and 24 connected to the end point of the pipe 21 are summarized as follows.
Pipe 22-pipe type: A, caliber: 100 mm, laying year: 1957 Pipe 23-tube type: A, caliber: 100 mm, laying year: 1958 pipe 24-tube type: C, caliber: 75 mm, laying year: γ Year Here, the pipe type of the pipe 21 is A, and the diameter is 100 mm. Therefore, the pipe 21, the pipe 22, and the pipe 23 are the same in terms of pipe type and diameter. Therefore, the attribute complementability determination unit 6 selects 1957, which is the older laying year of the pipes 22 and 23, as the representative value of the starting point in the pipe 21.

Therefore, the representative value of the start point in the pipe 21 is acquired as 1960, and the representative value of the end point is acquired as 1957. In this way, when the representative values are different between the start point and the end point of the tube of unknown attribute, the attribute complementability determination unit 6 determines that the attribute complement is possible, and the attribute complement unit 7 determines that the attribute complement is possible, as shown in FIG. , 1957, which is the older laying year, is supplemented as the laying year of the pipe 21.

(How to supplement the pipe type)
Next, as an attribute related to the pipe, a complementing method when complementing the pipe type will be described. FIG. 6 is a diagram showing complement conditions when complementing pipe types, and FIG. 7 is a schematic diagram showing an example of a piping network when a plurality of pipes are connected to the start point and end point of a pipe of unknown attribute. Is.

As shown in FIG. 6, the conditions for supplementing the pipe type are generally the same as those for supplementing the laying year. However, if the representative values of the start point and the end point of the tube of unknown attribute are different, the attribute complementability determination unit 6 determines that complementation cannot be performed.

A method of performing attribute complementation for the tube type will be described with reference to FIG. For example, it is assumed that the pipe type of the pipe 11 is unknown, and the pipe types of the pipe 10 and the pipe 12 are HIVP (High impact resistance unplasticized poly (vinyl chloride) (PVC-U) pipe). In this case, the attribute complementability determination unit 6 determines that the attribute complement is possible. Further, the attribute complementing unit 7 complements the HIVP as an attribute related to the tube 11.

A method of complementing the pipe type of the pipe 21 which is a pipe of unknown attribute will be described with reference to FIG. 7. As shown in FIG. 7, the pipes 21 are connected to the pipes 18 to 20 at the start point and the pipes 22 to 24 at the end point. Further, the balloon in FIG. 7 shows the attributes related to each pipe.

In performing complementation, the attribute complementability determination unit 6 first acquires representative values of the start point and the end point of the pipe 21. As shown in FIG. 7, the attributes of the pipes 18, 19 and 20 connected to the starting point of the pipe 21 are summarized as follows.
Pipe 18-pipe type: HIVP, caliber: 75 mm, laying year: 1980 Pipe 19-tube type: DCIP (Ductile iron pipe), caliber: 100 mm, laying year: 1980 Pipe 20-tube type: DCIP, caliber: 100 mm , Installation year: 1990 Here, since the diameter of the pipe 21 is 100 mm and the laying year is 1980, the attribute complementability determination unit 6 is a DCIP which is a pipe type of the pipe 19 having the same diameter and the laying year. Is selected as the representative value of the starting point in the pipe 21.

Further, as shown in FIG. 7, the attributes of the pipes 22, 23 and 24 connected to the end point of the pipe 21 are summarized as follows.
Tube 22-Pipe type: DCIP, caliber: 100 mm, laying year: 1980 Pipe type: DCIP, caliber: 100 mm, laying year: 1980 Pipe type: VP (unplasticized poly (vinyl chloride) (PVC) -U) pipe), caliber: 50 mm, laying year: 1990 That is, the caliber and laying year of the pipe 21 and the pipe 23 coincide with the caliber and laying year of the pipe 21. Here, since the pipe types of the pipe 21 and the pipe 23 are both DCIP, the attribute complementability determination unit 6 selects DCIP as the representative value of the starting point in the pipe 21.

Therefore, the representative values of the start point and the end point in the pipe 21 are both DCIP. The attribute complementability determination unit 6 determines that the attribute complement is possible, and the attribute complement unit 7 complements the DCIP as the tube type of the tube 21 as shown in FIG.

For example, in the above example, when the pipe type of the pipe 22 is VP, the pipe type of the pipe 22 and the pipe 23 that match in the diameter and the year of laying are different from the pipe 21 which is a pipe of unknown attribute. In this case, the representative value of the end point is not acquired, and the attribute complement unit 7 complements DCIP, which is the representative value of the start point, as the tube type of the tube 21.

Similarly, when the pipe type of the pipe 22 and the pipe 23 is VP, the representative value of the end point is VP. In this case, since the representative values of the start point and the end point are different, the attribute completion possibility determination unit 6 determines that the attribute completion cannot be performed.

As mentioned above, when the attributes of a pipe include the pipe type, diameter, and laying year, for a pipe of unknown attribute, either the pipe type or the laying year is unknown, and other than the unknown element. When the two elements of the above are known, the attribute complementability determination unit 6 is known among the attributes in the attribute unknown tube regarding the attributes related to the attribute known tube connected to each of the start point and the end point of the attribute unknown tube. If the degree of matching with the two elements is low, it is determined that the unknown attribute cannot be complemented for the attribute unknown tube, and if the above matching degree is high, it is determined that the unknown attribute for the attribute unknown tube can be complemented.

The "degree of consistency" indicates how much the attributes match between one pipe and another. In addition, the criteria for determining the degree of consistency as "high" or "low" to the extent that it can be complemented differ depending on the attribute to be complemented. This point will be described more specifically by taking the “laying year” supplement according to FIGS. 4 and 5 and the “tube type” complement according to FIGS. 6 and 7 as examples.

First, the "laying year" supplement according to FIGS. 4 and 5 will be described. As shown in FIG. 4, the conditions for complementation for the laying year are (1) when the representative values of the start point and the end point are the same, (2) when the representative values of the start point and the end point are different, and (3) the start point. There are three types when the representative value is acquired only for either the end point or the end point.

What all three types have in common is that representative values can be obtained at at least one of the start point and the end point. In other words, a tube of unknown attribute can obtain representative values for at least one of the start point and the end point if the attributes match to some extent with the tube connected at its start point and end point.

On the other hand, as shown in FIG. 4, when neither the start point nor the end point can obtain the representative value, the supplementation of the laying year is not carried out. The fact that the representative value cannot be obtained for either the start point or the end point means that the attribute unknown tube does not match the attribute of the connected tube at the start point and the end point so much, the representative value. Is not possible to get.

Regarding the complementation related to the above-mentioned laying year, when the complementation is done and the complementation is not done, in the cases of (1) to (3) above, it is judged that the "degree of consistency" is "high" and the starting point. If neither the representative value nor the end point can be obtained, it is judged that the "matching degree" is "low". That is, the possibility of complementation is determined based on the "degree of consistency".

Further, the "tube type" complement according to FIGS. 6 and 7 will be described. As shown in FIG. 6, the conditions for complementing the pipe type are as follows: (1) When the representative values of the start point and the end point are the same, (2) Only one of the start point and the end point is acquired. There are two types when it is.

What is common to these two types is that only one representative value is acquired at the start point and the end point. In other words, a tube of unknown attribute has some degree of attribute matching with the tube connected at its start and end points, and also to some extent between the tube connected at the start point and the tube connected at the end point. If the attributes match, one type of representative value can be obtained from at least one of the start point and the end point.

On the other hand, as shown in FIG. 4, the conditions under which the tube type is not complemented are (3) the representative values of the start point and the end point are different, and (4) the representative values of neither the start point nor the end point cannot be obtained. There are two types.

What these two types have in common is that the representative values acquired at the start point and the end point are not one type. In other words, a tube of unknown attribute does not have much attribute matching with the tube connected at its start and end points, or a tube of unknown attribute has some degree of attribute matching with the tube connected at its start and end points. Also, if the attributes do not match so much between the pipes connected at the start point and the pipes connected at the end point, it means that the acquired representative value is not one type.

Regarding the complementation related to the above-mentioned pipe type, when the complementation is performed and the complementation is not performed, in the cases of (1) and (2) above, it is judged that the "degree of consistency" is "high", and the above In the cases of (3) to (4), it is judged that the "degree of consistency" is "low". That is, the possibility of complementation is determined based on the "degree of consistency".

In this way, the attribute complementability determination unit 6 aligns the attributes related to the known attribute tubes connected to the start point and the end point of the unknown attribute tube with the two known elements of the unknown attribute tube. If the degree is low, it is determined that the unknown attribute cannot be complemented for the attribute unknown tube, and if the degree of matching is high, it is determined that the unknown attribute for the attribute unknown tube can be complemented.
