In various plants, a large number of devices constituting the plant are supplied with power by a power panel. Therefore, the individual devices and the power supply panel are connected by a number of cables for supplying power to the devices. Depending on the configuration and size of the plant, it is necessary to connect several hundred cables in a single plant at an optimal distance between predetermined devices. Most of the cables are It is stored in an electric circuit material represented by a cable tray and a conduit, and is protected from the outside.
Conventionally, the installation route and size selection of the electrical circuit material that stores the cable is performed manually by the plant designer or operator in consideration of the arrangement relationship between the devices, cable size, laying conditions, etc. The work could take months.

Therefore, a plant design system using a three-dimensional figure processing apparatus such as a CAD (Computer Aided Design) system has been proposed in order to rationalize the plant design including the arrangement of electric circuit materials and the like.

A design system is described. In order to streamline the work of installing electrical circuit materials (cable trays) in a plant, it has been proposed to block cable trays.
For example, Patent Document 2 describes that a cable tray that is assembled and united on the ground using a multistage frame and a cradle is lifted, fixed at a high place, and fixed to a building. Is done.

When the input of design data such as the equipment model and the space factor input by the plant designer in step S1004 of FIG. 2 is received from the input unit 3, the optimum electrical circuit design automatic selection unit 121 removes the cable from the material model database 102. Data such as the diameter d, the height h and the width w of the electric circuit material is extracted to select the route of the electric circuit material (step S2001). A known technique is used as a method of selecting the route of the electric circuit material. Further, the electric circuit material selected in step S2001 is the electric circuit material of the smallest size among the sizes stored in the material model database 102. In the embodiment of the present invention, the electric circuit materials are selected in ascending order, but may be selected in the descending order.
Hereinafter, the optimum electrical circuit design automatic selection unit 121 repeats the processes in steps S2002 to S2009 for the electrical circuit material on the route of the selected electrical circuit material.
The optimum electrical circuit design automatic selection unit 121 applies the extracted data to (Equation 1) to determine whether the space factor of the selected cable falls within the allowable value of the space factor of the selected electrical circuit material. Determination is made (step S2002).

Here, h is the path member height, w is the width of the path member, d _n is the outer diameter of the cable to be stored in the electric path member, the number of cables n to be stored n = k [present] Suppose that
When the cable space factor is within the allowable value in (Expression 1) (“Yes” in step S2002), the optimum electric circuit design automatic selection unit 121 stores the data on the selected electric circuit material, cable, route, and the like in the material model database. 102 (database) is temporarily input and stored (step S2003).

Next, the optimum electric circuit design automatic selection unit 121 determines whether or not the electric circuit material does not interfere with other equipment and piping in the selected route (step S2005). Here, the determination of interference by the optimum electrical circuit design automatic selection unit 121 is an existing technology and will not be described in detail. However, by checking whether or not the electrical circuit material and other equipment and piping do not overlap in terms of coordinates, the interference is determined. The presence or absence of is determined.
When the electric circuit material interferes with other equipment or piping (“Yes” in step S2005), the optimum electric circuit design automatic selection unit 121 selects an electric circuit material of one smaller size (step S2006), and proceeds to the processing of step S2008. Then, in a state where the electric circuit material is replaced by one smaller size, the location where the interference is generated is highlighted by changing the display color of the corresponding electric circuit material portion.

  In addition, when the electric circuit material selected in step S2005 causes interference with other equipment and piping (“Yes” in step S2005), a new electric circuit material of one smaller size, that is, a new dimension (h , W) from the material model database 102, the space factor may be reset via the input unit 103, and the space factor may be recalculated.

If the electric circuit material does not interfere with other equipment or piping (“No” in step S2005), the optimum electric circuit design automatic selection unit 121 determines the selected electric circuit material size and route, and classifies the electric circuit material according to the type and size of the electric circuit material. The data is automatically input to the material model database 102 (step S2007), data is accumulated, and the process is terminated.
When the cable space factor exceeds the allowable value in (Equation 1) (“No” in step S2002), the optimum electrical circuit design automatic selection unit 121 determines whether or not the electrical circuit material of one size can be selected. Determination is made (step S2004).

When one larger size electric circuit material can be selected (“Yes” in step S2004), the optimum electric circuit design automatic selection unit 121 selects one larger size electric circuit material, and the new size (h , W) is acquired from the material model database 102, the process returns to step S2002, and the space factor tolerance is recalculated.
In addition, when an electric circuit material of one larger size cannot be selected (“No” in step S2004), that is, when there is no electric circuit material model data 112 of a larger size in the material model database 102, the optimum electric circuit design automatic selection unit 121 is selected. Changes the display color of the electrical circuit material part for which the optimal electrical circuit material could not be selected and outputs it to the output unit 105 (step S2008), notifies the user, and reselects the cable route (step S2009). The process returns to step S2002.

Next, the optimum electric circuit material block design process (step S1006 in FIG. 2) will be described.
FIG. 4 is a flowchart showing the flow of the optimum electric path material block design process of the electric path material installation work design unit 104.
The optimum electrical path material block design unit 122 of the electrical path material installation work design unit 104 performs the processing result (route, size, mass, etc. of the electrical path material) and the design data 120 ( Carry-in space, loading capacity of heavy equipment, etc.) are extracted from the material model database 102 (step S3001). If the loading capacity of heavy equipment is registered in the heavy equipment model data 118 in advance, it may be read.

Next, the optimum electrical circuit material block design unit 122 acquires heavy equipment model data 118 relating to the heavy machinery used in the plant design, and divides the electrical circuit material in a range (dimensions) that can be mounted on the heavy machinery (step S3002). The optimum electrical path material block design unit 122 refers to the dimensions of the heavy equipment model data 118 (the dimensions of the loading platform, etc.) and divides the electrical path material range in which the heavy equipment can be loaded (reference numeral B0001 in FIG. 5).
The optimum electric circuit material block design unit 122 confirms the division point of the electric circuit material located closest to the division range, and re-divides the electric circuit material range so as to match the division point (step S3003: FIG. 5). Code B0002). Thereby, the electric circuit material range which can be mounted on a heavy machine and conforms to an actual electric circuit material dividing point is created as a block. A division | segmentation point is corresponded to the junction part of electric circuit materials.

Next, the optimum electrical path material block design unit 122 refers to the loading capacity of the heavy equipment model data 118 and the mass in the electrical path material model data 112, and the weight of the block divided by the heavy equipment in step S3003 is the heavy equipment loading capacity. It is determined whether the capacity is within the range (step S3004).
When the divided blocks cannot be stacked by heavy machinery (“No” in step S3004), the optimum electrical path material block design unit 122 further shifts the division point inward in the divided blocks (step S3006), The block is made smaller, and the process returns to step S3003 to reselect the block.

When the divided blocks can be loaded by heavy machinery (“Yes” in step S3004), the optimum electrical path material block forming design unit 122 determines whether the divided blocks satisfy the carry-in space (step S3005), that is, It is determined whether it can be brought in. The electric circuit materials included in the divided blocks are assembled into blocks on the ground, transported by heavy machinery, and are lifted, for example, on a ceiling portion of a building and installed by performing welding work or the like. Therefore, in step S3005, it is determined whether or not it can be carried in. When the heavy machine transports the divided block to a predetermined installation position and installs it, it interferes with a structure attached to the building or other equipment or piping. Is determined. The determination of interference is the same as that described above, and thus the description thereof is omitted.
In step S3005, when it is determined that interference with a building structure or the like occurs when the block is carried in, the optimum electrical path material block design unit 122 generates a three-dimensional image 140 in which the display color of the portion where the interference occurs is changed. It is also possible to output to the output unit 105.

If the divided block does not satisfy the carry-in space (“No” in step S3005), the optimum electric circuit material block design unit 122 further shifts the division point inward in the divided block (step S3006), Decrease and return to step S3003.
If the divided block satisfies the carry-in space (“Yes” in step S3005), the optimum electrical circuit material block design unit 122 stores information on the divided block in the material model database 102 (database) (step S3007), the area of the connection surface of the electrical path material points of the divided blocks is calculated (step S3008), and the welding range is calculated (step S3009).

The optimum electric circuit material block design unit 122 extracts work efficiency from the material model database 102 or the design data 120, and calculates the number of workers necessary for welding in the welding range calculated in step S3009, the number of construction days, and the like (step). S3009).
Output data 130 such as the range of blocking, the amount of blocked products, the number of workers, the number of days required for construction, and the like calculated by the optimum electrical path material blocking design process shown in FIG. 4 is output to the output unit 105 (step S1006 in FIG. 2) ). Further, the loading route of the electric circuit material block in step S3005 is output to the output unit 105 as a three-dimensional image 140.

Next, the processing shown in FIGS. 2, 3, and 4 will be specifically described with reference to FIG.
FIG. 5 is a diagram illustrating an application example of the electric circuit material installation work design.
The plant designer displays a three-dimensional image of the plant on the output unit 105 using three-dimensional CAD, installs the equipment model M001 and the power supply model P001 in the plant, and arranges the equipment model (step S1002).
The optimum electric circuit design automatic selection unit 121 extracts data such as cables suitable for connecting the device model M001 and the power supply model P001 from the material model database 102 (step S1003), and the space factor necessary for electric circuit material design, Design data 120 such as a carry-in space is received from the input unit 103 (step S1004), and the electric circuit materials T005, T006, T007, T202, T203, C012, T204, T205, T206, and T207 (in FIG. 5) that match the extracted cable model. The electrical path material route R001 indicated by the solid line is selected (step S2001).

  Next, the input space factor is “30%”, and the optimum electrical circuit design automatic selection unit 121 performs the electrical circuit materials T005, T006, T007, T202, T203, C012, T204, T205, T206, T207 on the route R001. 3 are performed in order. As a result of the processing, when the electric circuit material T005 does not satisfy the allowable space factor of step 2002, the optimum electric circuit design automatic selection unit 121 selects an electric circuit material of one size larger as the electric circuit material T005 (step) S2004). If the selected electric circuit material T005 of one larger size satisfies (Equation 1) in step S2002, but interferes with the device model M001 in step S2005, (in terms of space factor), the small electric circuit material in route R001 The optimum electric circuit design selection unit 121 displays the electric circuit material T005 on the three-dimensional image 140 by changing the display color (step S2008), and reselects the cable route (step S2009). . For example, an electric circuit material route R002 composed of electric circuit materials T102, T103, C011, T014, T015, T016, T017, T204, T205, C021, T206, and T207 indicated by dotted lines in FIG. 5 is reselected. The

Further, the optimum electric circuit material block design unit 122 acquires the heavy equipment model data 118 relating to the heavy equipment used in the plant design shown in FIG. 5 (step S3001), divides the electric circuit material within a range that can be mounted on the heavy equipment, and B001 is obtained (step S3002).
The optimum electrical path material block design unit 122 confirms the division point of the electrical circuit material that is closest to the division range B001 (that is, the junction of the electrical path material), and matches the division point with the electrical path material range. Are subdivided to obtain a divided block B002 (step S3003).

Next, the optimum electrical path material block design unit 122 refers to the loading capacity of the heavy equipment model data 118 and the mass in the electrical path material model data 112, and the electrical path material quantity of the divided block B002 is within the range of the heavy equipment loading capacity. Is determined (step S3004). For example, when the weight of the divided block B002 is 200 [kg] and the lifting load capacity of the heavy machine (lift machine) is 1000 [kg], it is determined that the load is within the load capacity range, and the process proceeds to the next step. .
When the electric path material amount of the divided block B002 is within the range of the loading capacity of the heavy equipment (“Yes” in step S3004), the optimum electric path material block design unit 122 falls within the range of the carry-in space where the divided block B002 is input. It is determined whether or not there is (step S3005). For example, the determination of whether or not it is within the range of the carry-in space is to confirm whether or not there is an interfering object when lifting the divided block B002 from below to a predetermined installation position. Here, when there is an interfering object, the electrical circuit material installation construction design apparatus 1 performs an output process such as displaying the interfering portion in the three-dimensional image 140 displayed on the output unit 105 by changing the display color. .

  When the divided block B002 is within the range of the carry-in space (“Yes” in step S3005), the optimum electrical path material block design unit 122 stores information on the divided block B002 in the material model database 102 (database) (step S3007), a connection surface between the electric circuit material of the divided block 002 and the electric circuit material of another block, for example, electric circuit material T202 and electric circuit material T203, electric circuit material T017 and T016, electric circuit material T018 and electric circuit material T019, electric circuit material T204 and electric circuit The area of each connection surface of the material T205 is calculated (step S3008), and the welding range is calculated (step S3009).

S3009).
In this way, the blocked B002 is assembled on the ground, carried into the installation site by the carry-in route calculated by the electrical path material installation work design apparatus 1, welded, and installed at the installation site.

  As described above, according to the electrical path material installation work design apparatus 1 according to the embodiment of the present invention, when the equipment model constituting the plant is arranged using the three-dimensional CAD, the cable and the electrical path material corresponding to the equipment model are arranged. Can be extracted, and an optimum electric circuit material route can be selected in consideration of design data.
