Description

The present invention relates to a wiring state presentation method and a wiring state presentation device for outputting information representing a wiring configuration of a wire harness.

In a vehicle, for example, it is necessary to individually supply power from a power source such as a main battery and an alternator (generator) to each of the many electrical components placed in various locations on the vehicle. be. Also, multiple electronic control units (ECUs) need to be interconnected so that they can communicate with each other. In addition, it is necessary to transmit signals output by various switches and sensors to a predetermined electronic control unit. In addition, it is necessary to individually control the on/off of various loads according to the signals output from the electronic control unit.

Therefore, in a general vehicle, each part of a wire harness, which is an assembly of many electric wires, is arranged along a predetermined wiring route on the vehicle, and each part on the vehicle is connected via the wire harness. .

In practice, several hundred wires, terminals, connectors, clamps, and other components are assembled according to the details of the design drawings, and arranged along the wiring route specified in the design drawings. The formed wire harness product is manufactured by a parts manufacturer. Then, the vehicle manufacturer manufactures the vehicle by assembling the wire harness purchased from the parts manufacturer to the vehicle body.

When manufacturing such wire harnesses, various matters such as overall weight reduction, workability during manufacturing, manufacturing cost reduction, and manufacturing quality must be considered. Therefore, various techniques related to wire harnesses have been conventionally proposed.

For example, Patent Literature 1 discloses a technique for optimizing joint positions from the viewpoint of total weight and cost when manufacturing a vehicle circuit body such as a wire harness. Specifically, based on the basic design data representing the configuration of the vehicle circuit body, visual information representing the wiring route and configuration of the vehicle circuit body is displayed on the screen, and joint part designation and optimization instructions are displayed. , automatically calculates the length of each wire and the total wire length when joint parts are placed at each of the different positions, and reflects the comparison result of the total wire length for each calculated position. , to display the optimal position of the joint site. It also displays the difference in total line length due to different positions. In addition to the total line length, changes in total weight and costs are considered to automatically determine the optimum position. Selection of positions other than the determined optimum position is also accepted.

Further, the manufacturing support method of Patent Document 2 shows a technique of outputting a number that is useful for improving the efficiency of work such as manufacturing, inspection, design change examination, etc. of a wire harness. Specifically, unique address information is generated for each node that represents each measuring point on the wire harness, the address information is assigned to the node on the output design drawing data, and when determining the number of the address information , assign numbers sequentially along the route of the wiring harness. Number assignment is started with the element position selected by user input as a base point. A smaller number is preferentially assigned to a node closer to the terminal in the routing route. When processing a branch node representing a branch point in a routing route, a smaller number is preferentially assigned to an attribute representing the characteristics of the branch node. A number with a small number of digits can be used, making it easier to grasp the connection relationship.

By the way, for example, when a wire harness to be mounted on a vehicle manufactured by a vehicle manufacturer (Company A) is manufactured by a parts manufacturer (Company B), normally design drawing data (Section 1 design drawing data) is provided from A company to B company. This design drawing data is data that can be used on a specific CAD (Computer Aided Design) system introduced by Company A, and is created as data in a format that is easy for Company A to use.

Company B manufactures wire harness products based on the design drawing data received from Company A. In addition, after confirming that the manufactured wire harness product satisfies the specifications required by Company A through an inspection including actual measurement of dimensions, Company B delivers the wire harness product that has passed the inspection to Company A. Company A mounts the wire harness delivered by Company B on a specific vehicle body and manufactures the vehicle.

In the environment as described above, Company B manufactures wire harnesses so as to conform to the first design drawing data received from Company A, but the first design drawing data is expressed in a format that is easy for Company A to use. Therefore, it is not expressed in a format that is easy for Company B to use when manufacturing wire harnesses.

Specifically, Company A gives priority to consolidating and expressing the connection relationships between each part of the wire harness and various in-vehicle devices in a drawing of a limited size. Therefore, in the first design drawing data, each element of the wire harness is represented in a form such as length, size, and shape different from the actual dimensions.

However, when Company B actually manufactures wire harnesses, in an actual three-dimensional space on a jig plate, workers sequentially process a large number of parts such as wires of various lengths, connectors, terminals, and exterior materials. , and arrange them so that they pass through the pre-determined wiring route and carry out the assembly work.

Therefore, in a situation in which various parts are arranged and assembled, the dimensions and shapes of each part do not match the contents of the first design drawing data. Therefore, although there is a possibility that there is a design defect in the first design drawing data, it is very difficult to find the defect from the contents because the wiring route and the like are different from the actual ones. In Company B, prior to the start of wire harness manufacturing, the designer hand-written an assembly drawing showing the actual wiring route and flow of each wire for each wire harness and each subassembly (ASSY) that constitutes it. was creating.

In addition, the designer investigates the presence or absence of design problems based on the contents of the drawings created by handwriting, and if any problems are found, asks company A to change the design and asks company A to send the correction data. It's becoming Also, the worker manufactures each subassembly of the wire harness while referring to both the handwritten assembly drawing and the first design drawing data. Furthermore, in order to confirm the wiring workability when actually manufacturing the wire harness, prototypes of the entire wire harness and each subassembly were created. Then, the designer reexamined the wiring route, etc., while looking at the created prototype. In addition, as a result of examination, when a change was required, a new assembly drawing was created again by the designer's handwriting, and a prototype was also created. Therefore, a lot of manpower and man-hours were required for the preparation from when Company B received the first design drawing data to when it started manufacturing the wire harness.

The present invention has been made in view of the circumstances described above, and an object of the present invention is to facilitate discovery of design defects in first design drawing data representing manufacturing specifications of wire harnesses.

Specific embodiments relating to the present invention will be described below with reference to each drawing.

<Specific example of first design drawing>
FIG. 1 is a front view showing a screen display example of first design drawing data relating to a wire harness.

For example, when a wire harness to be mounted on a vehicle manufactured by a vehicle manufacturer (Company A) is manufactured by a parts manufacturer (Company B), a first design drawing showing the specification of the wire harness required by Company A is normally used. 100A is provided by Company A to Company B. This design drawing data is data that can be used on a specific CAD (Computer Aided Design) system introduced by Company A, and is created as data in a format that is easy for Company A to use.

Company B manufactures wire harness products based on the design drawing data received from Company A. In addition, after confirming that the manufactured wire harness product satisfies the specifications required by Company A through an inspection including actual measurement of dimensions, Company B delivers the wire harness product that has passed the inspection to Company A. Company A mounts the wire harness delivered by Company B on a specific vehicle body and manufactures the vehicle.

For example, Company B uses dedicated application software for handling the data of the first design drawing 100A on a general-purpose computer, reads this data, and converts the contents of the drawing into a form such as a plan view as shown in FIG. can be displayed with

The data of the first design drawing 100A includes information specifying each of the many parts that make up the target wire harness, the connection relationship between parts, the wiring configuration of each electric wire, the dimensions (actual dimensions) between measurement points, and the like. Contains information. A wire harness is basically an assembly of electric wires in which a large number of electric wires are bundled. Types of parts that constitute wire harnesses include electric wires, terminals, connectors, clamps, tubes, tapes, and the like. Each measurement point is assigned to a node, such as each branch point, connection point, structural principal point, etc. on the wiring harness. Further, in recent years, wire harnesses often consist of a main line constituting the main part and a large number of branch lines extending from the main line.

<Description of an expression example of the configuration of the wire harness>
2(a) and 2(b) are plan views showing a simplified configuration example of the intermediate part 10A of the wire harness, FIG. b) shows an example of expression reflecting the actual size. When applying the present invention, an expression form as shown in FIG. 2(b) is used.

The intermediate component 10A shown in FIG. 2(a) includes an end component 11, a wire or wire assembly 12A, a connection component or node 13, a wire or wire assembly 14A, a connection component or node 15, a wire or wire assembly 16A, and end pieces 17 as elements.

In the intermediate component 10A, the actual size SZ of the wire or wire assembly 12A connecting between the terminal component 11 and the connecting component or node 13 is "100". Further, the actual size SZ of the wire or wire assembly 14A connecting between the connection part or node 13 and the connection part or node 15 is "200". Also, the actual size SZ of the wire or wire assembly 16A connecting between the connecting part or node 15 and the terminal part 17 is "300".

However, in company A, the actual size SZ of each electric wire or electric wire assembly 12A, 14A, 16A is not very important at the initial design stage, and as a result, the intended in-vehicle equipment and the predetermined position of the predetermined connector of the wire harness are used. There is no problem if it is a structure that can be connected with Therefore, in the drawing of the intermediate component 10A shown in FIG. 2(a), the length of the figure of each electric wire or electric wire assembly 12A, 14A, 16A is expressed independently of the actual size SZ, that is, in the free dimension format. be. Therefore, even when a long electric wire is included, a large number of constituent elements can be displayed within a limited narrow drawing area.

On the other hand, in the case of company B, which actually manufactures wire harnesses based on this specification, it is necessary to manufacture actual products, so the actual size SZ of each element constituting the wire harness is very important. For example, the designer of Company B must determine whether or not the wire harness can be manufactured according to the specifications, and consider the possibility of occurrence of defects. In such a study, it is very difficult to understand the actual situation with the contents of the drawing as shown in FIG. 2(a). Therefore, it was necessary for the designer to manually create an easy-to-understand drawing each time, or to create a prototype of the wire harness.

On the other hand, the intermediate part 10B shown in FIG. 2(b) is represented in the drawing while reflecting the actual size SZ. The intermediate component 10B shown in FIG. 2B represents the same component as the intermediate component 10A shown in FIG.

For example, in FIG. 2B, the figure (line segment, etc.) representing the electric wire or electric wire assembly 12B is displayed with a length proportional to its actual size SZ "100". Similarly, the graphic representing the wire or wire assembly 14B is displayed with a length proportional to its actual size SZ "200", and the graphic representing the wire or wire assembly 146 is displayed with a length proportional to its actual size SZ "300". is displayed.

<Example of realistic representation of wire harness configuration>
FIG. 3(a) shows a practical configuration example of the intermediate component 10A shown in FIG. 2(a). FIG. 3(b) shows a practical configuration example of the intermediate component 10B shown in FIG. 2(b).

Also in FIG. 3(a), the lengths of the respective electric wires or electric wire aggregates 12A, 14A, 16A that constitute the intermediate part 10A are represented by figures irrelevant to the actual size SZ. In the example of FIG. 3(a), the wire or wire assembly 14A has two bending points 14Aa and 14Ab on its way, and these shapes are reflected in the wiring route in the figure.

In the middle part 10B of FIG. 3(b), wires or wire bundles 12B, 14B and 16B are represented by figures having lengths proportional to their actual sizes SZ, as in FIG. 2(b). In FIG. 3A, the electric wire or electric wire assembly 14A has break points 14Aa and 14Ab, but in FIG. It is

<Actual size processing -1>
FIG. 4 shows the contents of the processing procedure-1 for converting the first design drawing data expressed in free dimensions to the actual size. FIG. 5 shows an example of the relationship between each measuring point on the intermediate part of the wire harness and the base point Pr.

For example, the data of the first design drawing 100A provided by Company A to Company B is read and processed using dedicated application software on a general-purpose computer (hereinafter referred to as a CPU), as shown in FIG. It is possible to execute the "actual size conversion process". As a result, for example, from an input drawing in a free dimension format such as the intermediate part 10A shown in FIG. can be generated.

The intermediate parts shown in FIG. 5 correspond to part of the content of the first design drawing 100A, and represent the wiring configuration of each part such as electric wires in the planar shape of the wire harness. In the example of FIG. 5, elements such as connection pieces or nodes 21, 23, wires or wire bundles 22, 24, 25, 26 are included in this intermediate piece.

A plurality of measuring points P01, P02, P03, P04, . Since the dimensions (actual dimensions) between these plural measuring points are determined in advance as product specifications required by Company A, Company B must manufacture wire harness products according to these specifications. The actual size data of each part is included in the data of the first design drawing 100A. The reference point Pr shown in FIG. 5 can be selectively designated by a user or the like from among a plurality of measurement points P01, P02, P03, P04, .

The "actual size conversion process" in FIG. 4 will be described below.
The CPU reads the input drawing data (corresponding to the first design drawing 100A) representing the specifications of the target wire harness from the previously prepared input drawing data file F1 and displays it on the screen (S10).

As a result, a drawing showing the configuration of the wire harness can be displayed in a display form such as that shown in FIG. 1, for example. However, in the display mode of FIG. 1, the actual size SZ of each element is not reflected in the display contents, as in FIGS. is difficult to grasp.

The CPU can accept user input while displaying the screen as shown in FIG. 1 (S11). For example, a user such as a designer selects one of the plurality of measuring points P01, P02, P03, P04, . . . shown in FIG. A selected measuring point can be designated as the base point Pr.

The CPU acquires the values of the dimension (actual dimension SZ) between the measuring points from the input drawing data file F1 (S12). For example, when processing the input drawing of the intermediate part 10A shown in FIG. respectively.

The CPU fixes the two-dimensional coordinates of the reference point Pr specified in S11, and actualizes each element of the drawing according to each dimension data acquired in S13 (S13). That is, with the reference point Pr as the origin, the positional coordinates representing the relative distance to the reference point Pr are calculated for each measuring point.

For example, when the node 13 is designated as the base point Pr for the intermediate part 10A shown in FIG. The point is moved to the left by "100" of the actual size SZ. Also, the position coordinates at the output of node 15 are a point shifted right from node 13 by "200" of the actual size SZ. In addition, the position coordinates in the output of the end part 17 are a point moved from the node 13 to the right by "200+300" of the actual size SZ. As a result, it becomes the same display form as the drawing of the intermediate component 10B shown in FIG.2(b).

In addition, the CPU identifies the presence or absence of a breakpoint for each part having dimensions (S14). For example, if there are breakpoints 14Aa and 14Ab as in the wire or wire assembly 14A shown in FIG. 3A, the process proceeds from S14 to S15 to straighten the breakpoints. That is, the wire or wire assembly 14A shown in FIG. 3(a) is changed into a linear figure at the bending points 14Aa and 14Ab. As a result, like the intermediate part 10B shown in FIG. 3(b), the entire wire or wire assembly 14B is represented by a straight, uncurved figure.

The CPU repeats the processing of S13 to S16 for all elements having dimensions (parts that do not need to be processed are excluded), and makes the display form of the output drawing actual size. When all dimensions have been processed, the process proceeds from S16 to S17, and the CPU displays the contents of the actual-sized output drawing on the screen. Furthermore, the data of the actual-sized output drawing is saved in the output drawing data file F2 as needed (S18).

By executing the "actual size process" shown in FIG. 4, the difference in the exact length of the plurality of electric wires and electric wire aggregates that make up the wire harness is correctly reflected on the screen. It is easy to visually grasp whether there is a problem in the wiring situation of the electric wire. Moreover, since the output drawing is generated on the output coordinates based on the base point Pr specified by the user, the part that the user wants to check can be displayed in an easy-to-see manner.

Furthermore, the points such as the break points 14Aa and 14Ab in FIG. 3(a) are linearized and expressed like the wire or wire assembly 14B in FIG. When comparing dimensions, the size relationship between dimensions can be easily grasped.

<Actual size processing -2>
FIG. 6 shows the contents of the processing procedure-2 for converting the first design drawing data expressed in free dimensions to the actual size. The contents of FIG. 6 are a modification of the "actual size conversion process" of FIG. 4, and only steps S21 to S24 and S17B are different from FIG.

The "actual size conversion process" in FIG. 6 will be described below.
The CPU reads the input drawing data (corresponding to the first design drawing 100A) representing the specifications of the target wire harness from the previously prepared input drawing data file F1 and displays it on the screen (S21). As a result, a drawing showing the configuration of the wire harness can be displayed in a display form such as that shown in FIG. 1, for example.

The CPU automatically detects the region of the trunk line of the wire harness based on the contents of the data of the input drawing (S22). Specifically, information on the diameter of each electric wire and the number of electric wires is acquired for each measuring point, and whether or not the corresponding position is a main line is identified based on this information. For example, locations where the sum of wire diameters is greater than or equal to a predetermined threshold, locations where extra-thick wires are included, and locations where the number of bundled wires is greater than or equal to a predetermined threshold are considered trunk lines.

For the entire area regarded as the main line in S22, the CPU visually changes each element such as each electric wire and measuring point to another area by coloring using a predetermined hue or by changing the brightness, saturation, etc. is highlighted and displayed so that it can be easily distinguished (S23).

The CPU can accept user input while displaying the screen as shown in FIG. 1 (S24). For example, a user such as a designer selects one of the plurality of measuring points P01, P02, P03, P04, . . . shown in FIG. A selected measuring point can be designated as the base point Pr. Further, for example, if there is no input operation by the user even after a predetermined time has passed, the base point Pr is automatically determined. In that case, among the measurement points existing on the trunk line, according to a predetermined priority, the position of the measurement point with the highest priority is determined as the reference point Pr.

Steps S12 to S18 in FIG. 6 are the same as in FIG.
In S17B, the CPU displays the actual-sized output drawing on the screen and highlights a portion of the drawing. For example, in the same way as in S23, the area of the main line and the area of each measuring point in the output drawing are displayed in a special color so that they can be distinguished.

When executing the "real-size processing" shown in FIG. 6, the base point Pr is specified on the trunk line of the wire harness, so that the actual-sized output drawing can be displayed in a more legible state. In other words, since the drawing can be displayed with the connection point between the main line and the branch line placed near the center of the screen, important points that need to be checked, such as branch points and connection points, are displayed in positions that are easy to see. can. In particular, there is a high possibility that part of the location where a long electric wire exists will protrude outside the screen when it is scaled to actual size. can avoid becoming invisible.

In addition, since the highlighting is performed in S23 and S17B, the user such as the designer can easily distinguish the positions of selectable measuring points, trunk line areas, etc. from other elements in the input drawing and the output drawing. Become.

It usually takes a long time for company B, which manufactures wire harnesses, to create the drawing data required for the actual manufacture of the product from the first design drawing data received from company A. However, by executing the "actual size conversion process" shown in FIG. 4 or FIG. 6 and displaying the actual size drawing, the design problem can be solved at an early point after Company B receives the first design drawing data. becomes easier to discover. In other words, it becomes possible for company B to find a design problem, feed back the result to company A, and shorten the time until the problem is solved.
