On the other hand, when it is determined in the determination process of S803 that the branch line 513 does not exist (NO), the design support device 100 performs a process of treating the wire harness 500 as a single wire harness (S806).

After performing the process of setting the position of the branch line 513 or performing the process of treating the wire harness 500 as a single wire harness, the coordinate conversion unit 133 of the design support device 100 performs the process of setting the terminal information ( S807: coordinate conversion step). Specifically, a process of converting information is performed so that the branch line 513 extends in a direction orthogonal to the trunk line 511.

After performing information conversion so that the branch line 513 extends in a direction orthogonal to the trunk line 511, the design support device 100 may perform a process of adding a member (member addition step). Examples of the member to be added include a label attached to the trunk line 511 and the branch line 513 of the wire harness 500, a connector, and the like.

When the member is added after the conversion process of S807 is performed in this way, it is easier to specify the position (coordinates) to which the member such as the label or the connector is added as compared with the case where the conversion process is not performed. Become.

Next, the design support device 100 performs a process of setting the bundle position (S808). In other words, a process of setting the bare dimension is performed, and a process of confirming the alignment between the length and the coordinate point is performed (S809).

When the coordinate transformation process shown in FIG. 18 is completed, the design support device 100 returns to FIG. 9 and performs a harness board drawing creation process (S900: manufacturing support step).
As shown in FIG. 19, the design support device 100 performs the process described below as the process for creating the harness board drawing. First, the size information unit 135 of the design support device 100 performs a process of examining the board size (S901).

The size information unit 135 performs arithmetic processing for setting size information regarding the size of the board display unit 202. The board display unit 202 is a display surface on which drawing information described later is displayed, and is also an arrangement surface on which the electric wire 501 is placed when the wire harness 500 in the harness digital board 201 is created.

When the size information is set, the manufacturing information unit 137 of the design support device 100 performs a process of creating manufacturing information including drawing information (S902). The drawing information is information displayed on the board display unit 202 of the harness digital board 201.

The wire harness 500 displayed by the drawing information is displayed with the same length (actual size or 1/1 scale) as the actual wire harness 500 in the length direction of the wire harness 500.

The radial direction or the width direction of the wire harness 500 may be displayed on the board display unit 202 with the same thickness or the same diameter as the actual wire harness 500. In this case, it is possible to visually recognize how thick the wire harness 500 is composed of the cable.

Further, when the wire harness 500 is manufactured, the number of electric wires 501 arranged on the board display unit 202 is too large or too small as compared with the case where the wires harness 500 is not displayed with the same thickness or the same diameter. It becomes easier for workers to notice. As a result, it becomes easy to reduce work mistakes when manufacturing the wire harness 500.

On the other hand, the radial direction or the width direction of the wire harness 500 may be displayed in a size not based on the actual wire harness 500. In this case, in particular, if the sizes of all the trunk lines 511 and the branch lines 513 displayed on the board display unit 202 in the radial direction (width direction) are the same, the drawing information can be easily created.

When the displayed thickness D2 of the wire harness 500 is displayed large, even if the electric wire 501 is arranged on the board display unit 202, it is difficult to hide in the electric wire 501 arranged by the displayed wire harness 500. Therefore, it becomes easy to improve the workability when manufacturing the wire harness 500.

However, in order to display the wire harness 500 in the frame of the size defined by the size information, the shapes of the trunk line 511 and the branch line 513 are deformed. In addition, a plurality of wire harnesses 500 may be displayed on the board display unit 202 at the same time.

When the manufacturing information is created, the gauge information unit 139 of the design support device 100 performs an arithmetic process for creating gauge information which is information of the tolerance gauge 631. The gauge information is information that causes the board display unit 202 to display the tolerance gauge 631. The created gauge information is included in the drawing information.

As shown in FIG. 7, the tolerance gauge 631 has a starting point which is one end of the electric wire 501 and an ending point which is the other end when the electric wire 501 is arranged on the board display portion 202 of the harness digital board 201. Represents the permissible range of positions where is placed. The position where the tolerance gauge 631 is displayed may be specified by the gauge information unit 139, or the position displayed by the operator may be changed or specified.

In the present embodiment, the tolerance gauge 631 will be described by applying it to an example in which the tolerance gauge 631 is displayed as a grid composed of frames having a predetermined pitch. As a predetermined pitch, a 5 mm pitch can be exemplified. The tolerance gauge 631 shown in FIG. 7 displays a positive tolerance and a negative tolerance. In addition to this, only the plus tolerance or only the minus tolerance may be displayed.

Further, the display mode of the tolerance gauge 631 is not limited to the display mode as a grid as in the tolerance gauge 631 of the present embodiment, as long as the tolerance range is clarified. For example, it may be a combination of line segments, or it may be a display mode of only a large frame which is an outer frame of a grid.

When the manufacturing information is created, the design support device 100 performs an output information creation process (S903). The output information is information created based on the manufacturing information. The output information includes CAD data created from drawing information, electronic data that can display drawing information on various information terminals (for example, PDF (Portable Document Form)), material list information, and wiring information for manufacturing. Is included.

When the output information is created, the design support device 100 performs output processing of the output information (S904). The created output information is distributed to the production base provided with the manufacturing support device 200.

When the process of creating the harness board drawing shown in FIG. 19 is completed, the design support device 100 automatically creates the manufacturing recipe and confirms whether the created manufacturing recipe and the wiring information match (S1000). First, as shown in FIG. 20, the design support device 100 performs a process of acquiring the format of the manufacturing recipe (S1001).

Next, the design support device 100 performs a process of acquiring wiring information before and after editing (S1002), and performs a process of comparing the wiring information before and after editing (S1003). The design support device 100 performs a process of determining whether or not the wiring information before and after editing matches based on the result of the comparison (S1004).

If it is determined that the wiring information before and after editing matches (YES), the recipe creation unit 141 of the design support device 100 performs a process of creating a manufacturing recipe based on the wiring information (S1005). ..

When the manufacturing recipe is created, the design support device 100 performs a process of creating material list information (also referred to as “BOM”) (S1006). Here, the material list information is information used for preparing members such as electric wires 501 and connectors 502 necessary for producing the wire harness 500. When the manufacturing recipe and the material list information are created, the design support device 100 performs a process of storing and outputting the manufacturing recipe and the material list information (S1007).

If it is determined in the determination process of S1004 that the wiring information before and after editing does not match (NO), the design support device 100 performs a process of displaying an error (S1008). After that, the process is canceled.

When the confirmation process of the recipe shown in FIG. 20 is completed, the total support system 1 returns to FIG. 9 and performs a wire harness manufacturing process (S1100: manufacturing support step).

The manufacturing support device 200 of the total support system 1 performs the process described below as a process for manufacturing the wire harness. First, as shown in FIG. 21, the control computer 211 of the manufacturing support device 200 performs a setup process for manufacturing the wire harness 500 based on the distributed output information (S1101).

When the setup process is completed, the control computer 211 performs a process of manufacturing the wire harness 500 (S1102). In the manufacturing process, the control computer 211 performs a process of displaying drawing information, gauge information, and an identifier according to the manufacturing process of the wire harness 500 on the board display unit 202.

The tolerance gauge 631 displayed by the gauge information is displayed at a predetermined position on the board display unit 202 by the control computer 211. Specifically, it is displayed near the position where the starting point, which is one end of the electric wire 501, and the ending point, which is the other end, are arranged.

The control computer 211 acquires the information of the identifier read by the reading unit 231 and stores the information for identifying the wire harness 500, the date and time of manufacture, the place of manufacture, and the like in the data server 221. As the identifier read by the reading unit 231, an electric wire 501, an identifier having information for specifying the connector 502 attached to the electric wire 501, and the like can be exemplified.

Further, the control computer 211 controls the electric wire cutting machine 241 and the printing machine 251 in response to the acquisition of the identifier information, and cuts and supplies the electric wire 501 of a desired type to a desired length. The supplied electric wire 501 is arranged on the board display unit 202, and the production of the wire harness 500 is advanced.

The material list information included in the output information is used for preparing members such as electric wires 501 and connectors 502 necessary for producing the wire harness 500. The arrangement of the wiring information for manufacturing is changed according to the processing order at the time of production of the wire harness 500. Wiring information for manufacturing is also called a recipe.

When the process of manufacturing the wire harness is completed, the created wire harness 500 is transported to the base where the body of the railroad vehicle is produced. As shown in FIG. 22, the information processing terminal 300 of the total support system 1 performs a process of supporting the wiring of the wire harness 500 (S1200: wiring support step).

In the wiring support process of the wire harness 500, first, the wiring process information and the wiring route information are distributed from the design support device 100 to the information processing terminal 300 (S1201). The delivered wiring process information and wiring route information are stored in the terminal storage unit 301.

The terminal control unit 311 of the information processing terminal 300 controls to display the wiring process information and the wiring route information according to the wiring process of the wire harness 500 (S1202). Specifically, the wire harness 500 is roughly classified as an assembly order STEP, and control is performed to display the wire harness 500 on the terminal display unit 321 according to the work order.

The information processing terminal 300 can also display the electronically converted drawing information included in the output information on the terminal display unit 321. The information processing terminal 300 can be used for work in the field of wiring. It can also be used to educate wiring workers.

The format of the wiring information that is the basis of the wire harness design may differ depending on the creator. If the format is different, the place where the information in the wiring information is referred to is different. Therefore, it takes time and effort to acquire the information necessary for the design, and the time required for the wire harness design increases. In addition, there is a risk of causing human error in wireness design.

On the other hand, according to the total support system 1 having the above configuration, the 2D design data of the wire harness 500 can be created based on the 3D design data, the basic wiring information, and the predetermined rules. In other words, instead of the wiring information having a format suitable for designing the wire harness 500 in three dimensions, the basic wiring information having a format not suitable for designing the wire harness 500 in three dimensions, and By obtaining a predetermined rule, it is possible to create 2D design data.

By making the rule based on the conversion rule data, it becomes easier to perform the conversion process of converting the basic wiring information into the wiring information by using an arithmetic processing device such as a computer, as compared with the case where the rule is not based on the conversion rule data.

By discriminating the content of the basic wiring information and selecting the rule, it is easier to create the basic wiring information and the wiring information based on the rule more appropriately than in the case where the content is discriminated and the rule is not determined. Become.

By creating the creation information, it is possible to determine whether the wiring information is created based on the basic wiring information and the rules. In addition, by including information such as the created date and time in the created information, the created date and time can also be determined.

Further, in the design of the wire harness, it takes time and effort to select the electric wire 501 to be made into a wire harness in consideration of the same place, equipment, and type of electric circuit (for example, AC electric wire, DC electric wire, shielded line). Was hanging. Further, the process could not proceed to the next process until the selection of the electric wire 501 was completed.

There are symmetry and similarities in the layout of multiple devices in the moving body (for example, in the case of railroad cars, on the left and right sides of each car), and with these in mind, the structure of the harness is also symmetric. It was necessary to design with the similarity in mind. It has further complicated the work to select the electric wire 501 for making a wire harness from among a large number of electric wires 501 in consideration of such symmetry and similarity.

On the other hand, by determining the combination of electric wires 501 to be combined as the wire harness 500 based on the area information or the application information, a more appropriate combination of the electric wires 501 can be obtained as compared with the case where the wire harness 500 is not based on the area information or the application information. It will be easier to judge. More specifically, it is possible to design while being aware of the symmetry and similarity of the wire harness 500.

By adding the wire harness discrimination information to the wiring information, it becomes easier to discriminate the wire harness 500 to which the electric wire 501 belongs from the wiring information, as compared with the case where the wire harness discrimination information is not given.

By setting a virtual electric wire using the connected device information and designing the wire harness 500 using the virtual electric wire, it becomes easier to shorten the time required for designing the wire harness as compared with the case where the virtual electric wire is not used. ..

By adding size information such as the diameter of the electric wire 501 to the wiring information and calculating the diameter of the virtual electric wire based on the size information, the accuracy of the designed wire harness 500 is improved as compared with the case where the diameter is not calculated. It will be easier to make.

By including the number assigned to each device in the connected device information, it becomes easier to identify the device as compared with the case where the number is not included.

Correspondence between the connector 502 and the device by creating 3D connector data which is three-dimensional data of the connector 502 and making the name of the data a name that can identify the device to which the connector 502 is connected. It becomes easier to understand the relationship. Alternatively, by setting the name of the data to a name that can identify the device to which the connector 502 is connected, it becomes easy to grasp the correspondence relationship between the connector 502 and the device. Further, as compared with the case where the name of the data is manually registered, it becomes easier to shorten the time and suppress the occurrence of human error such as an input error of the name.
As described above, the name of the 3D connector data may be a name that can identify the device to which the connector 502 is connected, or the name of the 2D connector data can be used to identify the device to which the connector 502 is connected. It may be a name.

By converting the coordinate system in the 2D design data to another coordinate system and adding the member according to the other coordinate system, the work of adding the member is performed as compared with the case where the member is added according to the original coordinate system. It will be easier.

The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, in the above embodiment, the object to which the wire harness 500 is wired may be an automobile body, an aircraft body, a ship hull, or the like, and is not limited to a railroad vehicle.
