For this reason, it is easy to respond to new business environment and new technology by reflecting its characteristics, eliminating purchase and maintenance costs for commercial tools, and making more efficient and scalable work with the database in conjunction with the database. An interface system is required.

As such, the existing commercial tools are required to develop unnecessary environments and programs according to parts that do not fit the company's environment, resulting in a maintenance cost. These problems have limited system scalability as well as system scalability to improve design problems.

Recent technological trends have highlighted the prominence and application of new technologies in the field of wiring, such as LAN and CAN, and demands a system that can support the early application and expansion of these new technologies.

Such interfaces are expected to continue to expand and expand in scope, for example, to continue to be updated along with the evolving automotive technology of continuous interface expansion.

The present invention was created to solve the above problems, to secure a unique interface to accumulate know-how, independent scalability beyond the technical dependence of the company that provides commercial tools and parts that commercial tools do not support An object of the present invention is to provide a wiring harness design drawing system and a method thereof.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is a block diagram schematically showing the configuration of the wiring harness design drawing generation system according to the present invention.

Referring to the drawings, the wiring harness design drawing generation system according to the present invention, for example, the circuit design information 21 of the electrical circuit design diagram 11 of the wiring harness of the vehicle, and the physical (or mechanical) path The route design information 22 of the schematic 12 is stored in the database 20 and the database 20, respectively, and the harness name information 31, the connector information 32, the harness joint information 33, and the signal are connected.

The logic information is provided in the database 20 and includes a project name and a harness name of the vehicle to which the wiring harness is applied.

The connector information 32 includes a product name to which the wiring harness is applied, such as a component name installed on the overall length of the vehicle, a connector name connected to the component, and pin information of the connector.

It includes a start connector part number, an end component part number, an end connector part number, and specification information about a wire configuration.

2 is a schematic flowchart sequentially illustrating a method for generating a wiring harness design drawing according to the present invention.

Referring to the drawings, in the wiring harness design drawing generation method according to the present invention, first, physical information and electrical information of the wiring harness are collected.

This means that the layout manager (instrument manager) generates a path in the vehicle to obtain physical information, and the circuit designer prepares the circuit diagram to obtain electrical information.

The physical information and the electrical information acquired in step 110 are collected to construct a layout information database and a circuit information database, respectively (step 120).

In step 120, the database information is interfaced.

In step 130, a drawing of the wiring harness is generated by the interface process (step 140).

In step 130, the interface process first receives route information from the database 20 based on the physical information (step 131).

Subsequently, circuit generation information is imported from the database 20 based on the electrical information (step 132).

The vehicle model harness name of the layout harness and the circuit information matching for each vehicle harness stored in the database 20 are checked (step 133).

In addition, the connector information is extracted and matched, and the harness joint information is matched (steps 134 and 135).

Subsequently, signal routing verification is performed and final verification is performed (steps 136 and 137).

On the other hand, in step 137, if the final verification is not satisfied by this, step 134 is performed again, and if it is satisfied, step 140 is performed.

In the step 140, the jig also generates a harness in a format (step 141).

Subsequently, information on the signal list is generated, and sub-part information is generated (steps 142 and 143).

In addition, harness protection information is generated, and connector information is generated (steps 144 and 145).

On the other hand, a system that starts with the fact that the information required by the harness is designed in the same or dissimilar environment (conditions), can support the development and development of physical and electrical and electronic designs simultaneously. It is not becoming.

It is also a problem that is related to the analysis and simulation according to the data characteristics, because the data composition itself requires different information.

Therefore, in the present invention, as described above, a circuit design including electrical and electronic elements is first made in a heterogeneous environment, and physical information including a location information including a spatial element in a vehicle and information about a route fixing point is included in a database. 20 is stored.

After that, a production drawing for the harness should be generated. Before that, the logic information and the physical information are verified. Matching of this information is based on layout path information. In addition, logic information corresponding to the basic information of the route information is obtained. The reason is that the partition is separated for harness assembly or workability, but the actual logic information is all information of one vehicle without partitioning. The extra information that is not included can reduce system performance and reduce work efficiency. When obtaining this logic information, the information is extracted with the vehicle project name and harness name.

For example, the logic information in the database 20 is composed of the project name and the harness name of the vehicle, and the harness model of the layout route information is also composed of the project name and the harness name of the vehicle. According to whether or not this match, it is possible to change the information when matching and matching operation. The obtained information is, for example, the connector information 32, the harness joint information 33, the signal information 34, the cable information 36 and the like absorbed into the layout information model.

This information is also included in the layout model information to enable verification of the contents. How this logic information is included in each part of the physical model is described with reference to FIG. 3 as follows.

First, A is a component of the vehicle and the electrical component that is connected to connector B in the wiring harness, which has an independent system name. B is a wiring connector, and the configuration information includes a component name, a connector name, and a pin name, and a portion where the wiring connectors are connected consists of a connector name and a pin name.

In addition, C is a branch of the basic unit of the harness, the interface requires only physical connection, D is a sub-part used for protecting and fixing the harness, and is not related to the interface with logic information. And E is mainly where the branch of the harness meets, which contains the harness joint information and the shield cable information.

And twisted cables only represent the information that a signal is tied to when it's routed.

When the A, B, C, D, E information is extracted from the physical model, and the part information is extracted, the location is identified, the start point of the signal obtained from the logic information is found, the connection in the space is traced, and the end is found and routed. When the matching operation is complete.

The verification of the signal routing at the beginning and the end is determined by the existence of components, connectors, and pins of the vehicle constituting the signal based on the path tracking, and the unrouted information is verified by distributing errors in the design. It is then fed back to finalize the verification by matching.

After performing such a series of process operations, as shown in Figure 4, the jig for the jig plate work for the fabrication of the curved physical three-dimensional harness (T) to create a path for manufacturing (JIG) A parallel harness F in the form of a figure is created using the system.

The signal information list table is reported to the drawing through a database. The form is shown in Table 1 below.

Circuit number Wire material Wire core outer diameter Wire collar Start connector name Start pin End connector name Tip pin Wire specification information 001 AVS 0.5 B CONN1 One CONN2 3 ABS

It then reports the subpart attached to the harness, which is independent of the interface since it exists alone in the physical model. Reports on protection (taping, tubing), etc., for harness protection are made, but these are also independent of the interface since they exist alone in the physical model.

Finally, the interface information is used to integrate the logic information flowing through the connector and the physical pin information to create a connector that is easy to read during manufacturing.

As described above, the wiring harness design drawing generation system and method thereof according to the present invention have the following effects.

It is possible to build an interface that suits the characteristics of the company, thereby improving the design quality of the wiring harness, accumulating the unique design know-how of the company, and owning the technology to improve the ability to respond to the new technology.

And traditional off-the-shelf tool interfaces that don't fit your environment can be eliminated, improving system and operator efficiency.

Wiring drawings can be automated by building an interconnected database and reducing the cost of purchasing and maintaining the tools used for the interface.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible. Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
