Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cable routing method and a recording medium,

[0001] The present invention relates to cable routing considering tray occupancy, and more particularly, to a cable routing method considering a tray occupancy that enables cable routing to be automatically performed in consideration of tray occupancy of a corresponding path, And a recording medium on which the method is recorded.

During the marine project, cables are installed for electrical and power systems and networks. Cable scheduling is required to optimize the installed cable, and cable routing is performed for cable scheduling. Here, cable routing refers to setting the path of a cable to be installed.

For cable routing, PML (Programmable Macro Language) of AVEVA MARINE (AM) is used as a ship development program, cable application of Abibamarin 12.0 or higher outfitting module is used as a routing environment, Has used HDM (Hull Drafting Module) of Abibamarin 12.0 or higher.

A typical cable routing method is based on a matrix using coordinates input from a CAD and physical distance information of a node and simply calculates a distance and calculates a distance based on the calculated distance information Sets only the distance path. The designer then visually examines the share of the cable tray based on the provided cable routing information, and when the occupancy rate is exceeded, the designer reassigns the route by specifying an alternative route. Here, exceeding the occupancy rate means that the cable stored in the tray exceeds the limit, that is, the amount of cable that can be accommodated in the tray is exceeded. Determine the occupancy based on the area or area of the tray.

On the other hand, a conventional technique for routing a cable in a marine project such as a ship is disclosed in the following Patent Document 1: Korean Patent Laid-Open Publication No. 10-2013-0060710 (published on June 10, 2013).

In the prior art disclosed in Patent Document 1, a tag number is assigned to a device related to a wiring diagram, and wiring diagrams and devices are also made consistent through tagging of an electrical device, thereby preventing a device from being missed or malfunctioning, Minimizing the workload.

In addition, by improving the design information through three-dimensional routing of the cable, it is possible to reduce the amount of cable and electric iron, and reduce the cable and tray work flow in the production department.

Korean Patent Laid-Open Publication No. 10-2013-0060710 (published on June 10, 2013)

However, since the common cable routing method as described above is simply the shortest distance-based cable routing method depending on the distance information of each node, since the share of the tray is not considered at all, the designer considers the tray share with the naked eye after the cable routing is completed And if it exceeds the occupancy rate, it is inconvenient to directly designate the alternative route.

For example, when the cable routing is completed and the cable routing information is provided, the designer examines the tray occupancy with the naked eye, and when the tray occupancy exceeds the limit, it is inconvenient to perform the rerouting after designating the bypass route.

In addition, when the designer individually designates the bypass path as described above, the designer selects the exclusion priority order at random, so that the tray occupancy rate of the other node exceeds the limit due to the alternative path, and designates the bypass path again And the like.

In addition, designation of a bypass route by a plurality of manual operations as described above and route reestablishment have caused frequent design changes, a lot of cable routing time, and waste of human resources.

In addition, since the conventional technique disclosed in Patent Document 1 is a cable routing method that does not consider the tray occupancy, there is a problem that cable routing must be performed again when the tray occupancy rate exceeds the limit.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a cable routing method considering a tray occupancy rate according to a preferred embodiment of the present invention and a recording medium on which the method is recorded will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a cable routing apparatus to which the present invention is applied and includes a standard information setting unit 10, an equipment and cable information receiving unit 20, a cable modeling database 30, a node and a main circuit information receiving unit 40, A cable routing unit 50 and a cable routing information database 60.

The standard information setting unit 10 sets standard information for routing. Here, the standard information includes at least one of a routing group code, a tray information, an MCT, a path setting priority, and a tray share application rule information.

Here, the path setting priority is set to the first order, the path based on the cable diameter (Out Diameter) is set to the second order, and the path based on the cable length is set to the third order . (OD-B) or OD-S (OD-S) may be set as priorities, and the cable length may be long (LEN-L) or short (LEN-S) .

In addition, the tray occupancy application rule information may include a rule for performing rerouting to remove a corresponding node and set a bypass path if the node can not be designated as a path because the tray occupancy rate is exceeded.

The equipment and cable information receiving unit 20 interworks with the enterprise resource management system (ERP system) to obtain pre-registered equipment, cable list information, and node and main circuit information.

The cable modeling database 30 stores cable tray modeling and cableway modeling result information including node and main circuit information. The node and the main circuit information can be easily obtained through the cable modeling database 30. [

The cable routing unit 50 performs automatic routing or smart routing based on the standard information, the equipment and the cable information, the node and the main route information, generates cable route information, and stores the generated cable route information in the cable routing information database 60 It plays a role.

FIG. 3 is a flowchart illustrating a cable routing method considering tray occupancy according to the present invention. (b) acquiring pre-registered equipment and cable list information and node and main path information through interworking with an enterprise resource management system (S12 to S13); (c) receiving node information including a path to be passed through (S14); (d) determining (S15) a cable routing option based on the standard information after step (c); (e) performing cable routing based on the routing priority and the tray occupancy when the cable routing option determined in the step (d) is smart routing, which is cable routing considering tray occupancy, and providing cable routing result information (S18, S17); (f) if the cable routing option determined in step (d) is automatic cable routing, performing automatic cable routing based on the shortest distance between nodes (S16).

A cable routing method considering the tray occupancy rate according to the present invention will be described in detail with reference to FIGS. 1 to 3. FIG.

First, when a designer inputs standard information to perform cable routing through the standard information setting unit 10, the cable routing unit 50 sets standard information for performing cable routing in step S11.

Here, the standard information may include at least one of a routing group code, a tray information, an MCT, a path setting priority, and a tray share application rule information.

The routing group code means an applicable code to be applied when calculating the cable occupancy rate of the node / primary route management. For example, if the occupancy rate code is "0", the occupancy rate is applied based on the outer diameter cross-sectional area of the cable. In case of "1", the sectional area or outer diameter of the cable is applied according to the project specifications.

The tray information is preferably cable tray-related shape information, and it is preferable to use standard tray information.

The path setting priority is set to the first order, the path based on the out diameter of the cable is set to the second order, and the path based on the cable length is set to the third order do. (OD-B) or OD-S (OD-S) may be set as priorities, and the cable length may be long (LEN-L) or short (LEN-S) . This routing priority means to set the cable circuit priority to be applied when smart routing is executed based on the cable schedule drawing number reference. That is, the routing priority is meaningless if the cable tray share is not exceeded, but it is crucial to determine the cable circuit priority to bypass if the cable tray share is exceeded.

FIG. 2 is a diagram illustrating a screen for setting the routing preference (smart routing option). On the left side of the system code management screen as shown in FIG. 2, items such as classification EP0, classification name-SMART-ROUTING option, and recognition classification P are items for setting the routing priority. When the above item is selected, items for setting the cable outer diameter, setting, and cable length are displayed as shown on the right side of the system code management screen. Clicking this item sets priority according to cable outer diameter and cable length.

In addition, the tray occupancy application rule information may include a rule for performing rerouting to remove a corresponding node and set a bypass path if the node can not be designated as a path because the tray occupancy rate is exceeded.

Through this process, standard information for cable routing is set, and in step S12, equipment and cable list information is acquired in cooperation with the enterprise resource management system. Various enterprise marine project design drawings are registered in the enterprise resource management system to extract equipment list information, tray list information, and cable list information. Therefore, it is possible to easily acquire the equipment and cable list information of the corresponding area through such a design drawing.

Next, in step S13, the node and the main circuit information are acquired based on the cableway modeling information stored in the cable modeling database 30. Since the cableway modeling information includes the node and the main path information, and the cable routing is a process performed after the cableway modeling, it is possible to easily obtain node and main path information using the cableway modeling information do. Here, a node means a branch point or an end point of a path, and a main path means a path between a branch point and a branch point.

Thereafter, in step S14, the designer designates a routing option including at least one of intermediate route designation, start and end nodes, and node length designation through the input device. Here, the option node is an option for specifying the intermediate path, and the start and end nodes are options for specifying the start and end nodes for setting the cable route, and the length designation is an option for specifying the cable length.

When the preliminary work for cable routing is completed by this process, it is confirmed in step S15 whether the designer has selected smart routing considering cable share. If the smart routing is not selected as a result of the check, the process moves to step S16 to perform the shortest distance-based automatic cable routing in the same manner as the conventional method. Then, in step S17, the cable routing result information obtained through the automatic cable routing is stored in the cable routing information database 60 and provided to the screen.

When the automatic cable routing is performed as described above, the designer determines the tray occupancy by visually checking the cable routing result information provided on the screen. If the tray occupancy rate is exceeded, the bypass node is manually designated again, There is an inconvenience to execute.

If it is determined in step S15 that the designer has selected smart routing, the process proceeds to step S18 where smart routing is performed considering tray occupancy.

For example, when the tray occupancy rate is exceeded, the tray occupancy rate is searched in real time while the cable route is set by routing the cable according to the routing priority among the standard information set in step S11, And then reroutes to search for the bypass path. Here, it is desirable to repeatedly search for the bypass route, and to determine that routing is impossible if there is no possible bypass route. If routing is disabled, the display shows the reason for not routing, which allows the designer to easily check the non-routable contents.

Here, the tray occupancy depends on the tray information.

That is, when the tray information is common (when the MCT is used), the cross-sectional area of the MCT insertion block (MIB) of the through-hole cable circuit is set as the reference occupancy rate. Here, the cross-sectional area of the MIB is calculated by multiplying the outer diameter of the MIB by the outer diameter of the MIB.

Also, if the tray information is Case 0, the cross-sectional area of the installed cable circuit is set as the reference occupancy ratio with respect to the cable tray allowable area. Here, the cross-sectional area of the cable circuit is calculated as (cable circuit outer diameter / 2) × (cable circuit outer diameter / 2) × 3.14.

Also, when the tray information is Case 1, the vector cross-sectional area of the external cable circuit of the routing cable group is set as the reference occupancy rate with respect to the cable tray allowable area by the routing group code.

In this case, when the routing group code is "M", the cable tray allowable area is set to the tray width, and the cross-sectional area of the cable cable circuit vector is set to the outer diameter x 3/2 when the outer diameter is 75 or more, 7/6.

In addition, when the routing group code is "L", the allowable cable tray area is set to the tray width, and the cross-sectional area of the cable cable circuit vector is set to the outer diameter x 4/3 when the outer diameter is greater than 57, The outer diameter is set to 0.7, and when the outer diameter is 25 or less, the outer diameter is set to 0.5.

If the routing group code is "l", the allowable cable tray area is set to the cable tray width, and the cross-sectional area of the installed cable circuit vector is set to (cable circuit outer diameter / 2) × (cable circuit outer diameter / 2) × 3.14.

Also, when the tray information is coaming-Rise, the reference occupancy rate is set as the cross sectional area of the through-hole cable circuit with respect to the inner area of the coaming type. Here, the Rise cross-sectional area is calculated as RISE outer diameter x RISE outer diameter.

As described above, according to the present invention, cable routing is performed in consideration of tray occupancy, so that when occupancy of a specific area exceeds a specified value (threshold value), it automatically closes the corresponding area and searches for a detour path, It is possible to reduce the number of times of bypassing by hand and to prevent the packing of material due to the bypass error.

Although the present invention has been described in detail with reference to the above embodiments, it is needless to say that the present invention is not limited to the above-described embodiments, and various modifications may be made without departing from the spirit of the present invention.

The present invention applies to cable routing technology in marine marine projects. Especially, it is applied to the technique of automatically routing the cable considering the tray share.
