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 of water and sewage systems, the pipe network data of the mapping system is used. The pipe network data is data indicating 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. Completion is to estimate the attributes of a tube whose attributes are unknown, based on the attributes of 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 by referring 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 a deviation in the network data supplemented for 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 an appropriate supplement, the labor cost is high and it is not realistic.

[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 pipe network, the input unit 3 acquires the pipe network data, and the control unit 2 complements and creates the pipe network attribute data based on the pipe network data. 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 identification 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 pipe having an unknown attribute, a pipe having a known attribute is referred to as a pipe with a known attribute. The attribute unknown pipe identification unit 5 outputs the arrangement of the specified attribute unknown pipe and the information of the unknown attribute to the attribute completion possibility determination unit 6.

The attribute completion possibility determination unit 6 is based on the pipe network data, the arrangement of the unknown attribute pipes acquired from the attribute unknown pipe identification unit 5, and the information of the unknown attributes, from the attributes of the known attribute pipes to the attributes related to the unknown attribute pipes. 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 related to 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 complementation possibility to the attribute complementation unit 7.

The attribute complementing unit 7 acquires the above-mentioned determination result regarding the complementability from the attribute complementability determination unit 6. When it is determined that the attribute unknown pipe can be complemented, the attribute complementing unit 7 refers to the pipe network data and complements the attribute related to the attribute unknown pipe based on the attribute related to the attribute known pipe. Further, the attribute complementing unit 7 outputs the attribute 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, the pipe network attribute data creation unit 8 outputs the pipe network attribute data to the attribute complementability determination unit 6 when the created pipe network attribute data includes a pipe with unknown attributes.

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 processing 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 pipe network data at 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 having 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.
(3) Attribute complement step: The attribute complement section 7 complements the attributes of the attribute unknown tube determined to be complementable.
(4) Piping network attribute data creation step: The piping network attribute data creating unit 8 creates piping network attribute data so as to include the complemented attributes of unknown pipes.

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, a 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 complementing 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 pipe of unknown attribute. And complement. Further, when the caliber is acquired for only one of the start point and the end point and the other caliber is not acquired, the attribute complementability determination unit 6 determines that the attribute can be complemented. Further, the attribute complementing unit 7 complements the acquired diameter as the diameter of the pipe of unknown attribute. Further, when the diameter is not acquired for both the start point and the end point of the pipe of unknown attribute, the attribute complementability determination unit 6 determines that the attribute cannot be complemented for the diameter.

In the above method, when the diameters of the start point and the end point of the pipe 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. To 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 13.

Next, the attribute complementability determination unit 6 determines that the attributes can be complemented for the pipe 12 by using the complemented diameters for the pipes 11 and 13. Then, the attribute complementing unit 7 selects and complements 100 mm, which is the larger diameter of 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 the 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 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, a complementing method when complementing the laying year will be described. FIG. 4 is a diagram showing complement conditions when complementing 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 of unknown attribute. Here, the representative value is an attribute unknown in the unknown attribute pipe related to the known attribute pipe connected to the start point and the end point of the unknown attribute pipe. When multiple known attribute pipes are connected to the start point or end point of the unknown attribute pipe, the attribute of the known attribute pipe that has the most matching elements with the known attribute among the attributes related to the unknown attribute pipe 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 complementation unit 7 sets the representative value as the laying year of the attribute unknown pipe. Complement as. If the representative values 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 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. In addition, the attribute complementing unit 7 complements the acquired representative value as the laying year of the pipe of unknown attribute. Further, when the representative values are not acquired for both the start point and the end point of the pipe of unknown attribute, the attribute complementability determination unit 6 determines that the attribute cannot be complemented 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 the complementation, the attribute complementability determination unit 6 first acquires the 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.
Pipe 18-tube type: B, caliber: 50 mm, laying year: β year Pipe 19-tube type: A, caliber: 100 mm, laying year: 1960 pipe 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 year of laying 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-tube 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 the pipe type and the 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 completion possibility determination unit 6 determines that the attribute completion is possible, and the attribute completion unit 7 determines that the attribute completion unit 7 is as shown in FIG. , 1957, which is the older laying year, is supplemented as the laying year of the pipe 21.

(Complementary method of 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 when supplementing for the laying year. However, if the representative values of the start point and the end point of the unknown attribute pipe are different, the attribute completion possibility determination unit 6 determines that the completion cannot be performed.

A method of performing attribute complementation for the pipe 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 completion possibility determination unit 6 determines that the attribute completion 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, 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. 7 shows the attributes related to each pipe.

In performing the complementation, the attribute complementability determination unit 6 first acquires the 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-pipe 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.
Pipe 22-Pipe type: DCIP, Diameter: 100 mm, Installation year: 1980 Pipe 23-Pipe type: DCIP, Diameter: 100 mm, Installation year: 1980 Pipe 24-Pipe type: VP (unplasticized poly (vinyl chloride) (PVC) -U) pipe), caliber: 50 mm, laying year: 1990 That is, the caliber and laying year of pipe 21 and pipe 23 coincide with the caliber and laying year of 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 pipe type of the pipe 21 as shown in FIG.

For example, in the above example, when the pipe type of the pipe 22 is VP, the pipe types of the pipe 22 and the pipe 23 that match in the diameter and the year of laying are different from the pipe 21 having an unknown attribute. In this case, the representative value of the end point is not acquired, and the attribute complementing unit 7 complements DCIP, which is the representative value of the start point, as the pipe type of the pipe 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 described 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 knows the attributes of the known attribute tube connected to each of the start point and the end point of the unknown attribute tube among the attributes of the unknown attribute tube. If the degree of consistency with the two elements is low, it is determined that the unknown attribute cannot be complemented for the tube with unknown attributes, and if the degree of consistency is high, it is determined that the unknown attribute for the tube with unknown attributes can be complemented.

The "degree of consistency" indicates how much the attributes match between one pipe and another. In addition, the criteria for judging 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” supplement 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 pipe with unknown attributes can obtain representative values for at least one of the start and end points if the attributes match to some extent with the pipes connected at its start and end points.

On the other hand, as shown in FIG. 4, if 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 a representative value cannot be obtained for either the start point or the end point means that, in other words, a pipe with unknown attributes has a representative value if the attributes do not match the pipes connected at the start point and end point. Is not possible to obtain.

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

In addition, the “tube type” complement according to FIGS. 6 and 7 will be described. As shown in FIG. 6, as conditions for complementing the pipe type, (1) when the representative values of the start point and the end point are the same, (2) the representative value of 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 pipe with unknown attributes has some degree of attribute matching with the pipe connected at its start and end points, and also to some extent between the pipe connected at the start point and the pipe 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 complementation is not performed for the pipe type 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 is common to these two types is that the representative values acquired at the start point and the end point are not one type. In other words, a pipe of unknown attribute does not have much attribute matching with the pipe connected at its start and end points, or a pipe of unknown attribute has some degree of attribute matching with the pipe 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 there is not one type of representative value to be acquired.

Regarding the complementation related to the above-mentioned pipe types, the cases where complementation is performed and the cases where complementation is not performed are summarized. In the cases (1) and (2) above, the "degree of consistency" is judged to be "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 pipes connected to the start point and the end point of the unknown attribute pipe with the two known elements of the unknown attribute pipe. If the degree is low, it is judged that the unknown attribute cannot be complemented for the unknown attribute tube, and if the degree of matching is high, it is judged that the unknown attribute for the unknown attribute tube can be complemented.

If the two known attributes of the unknown attribute pipe have a high degree of matching with respect to the pipes connected to the start point and the end point of the unknown attribute pipe, the attribute completion determination unit determines the unknown attribute pipe. Judging that it is possible to complement unknown attributes about,
The attribute complementing unit is characterized in that the pipe type or laying year of which the attribute unknown pipe is unknown is complemented so as to match the pipe type or laying year of the pipe connected to the start point or end point of the attribute unknown pipe. The data creation device according to claim 1. This is a data creation method used to analyze the piping network.
Of the plurality of pipes constituting the piping network, a pipe having an unknown attribute is specified as a pipe having an unknown attribute, and a pipe identification step having an unknown attribute.
Among the piping networks, an attribute complementability determination step for determining whether or not the attribute related to the attribute unknown pipe can be complemented from the attributes of the attribute known pipe with known attributes, and
When it is determined in the attribute complementability determination step that complementation is possible, the attribute complement step that complements the attribute related to the attribute unknown tube based on the attribute related to the attribute known tube, and the attribute complement step.
A piping network attribute data creation step for creating piping network attribute data indicating attributes related to a plurality of pipes constituting the piping network so as to include the attributes of the pipe of unknown attribute complemented by the attribute complementing step is provided. A data creation method characterized by being present. A program characterized in that a computer functions as each part of the data creation device according to claim 1.
