Description

How to create image file of electric circuit diagram for vehicle {METHOD FOR IMAGE FILE FORMATION OF VEHICLE CIRCUIT DIAGRAM}

The present invention relates to an electrical circuit diagram of a vehicle, and more particularly, to a method for generating an image file of an electrical circuit diagram for a vehicle capable of interpreting and tracking signal connection information between circuit diagrams.

In general, a wire harness (electric field) that electrically connects and functionalizes electric and electronic components in a vehicle plays a role of nerves and blood vessels in a vehicle, and is connected to a circuit for transmitting an electrical signal or power, required voltage and current. Functions such as supplying, preventing electromagnetic leakage of adjacent circuits, eliminating electrical shorts, etc. are required, and at the same time, the ease of operation and installation reliability are required for the installation of complicated wiring.

Therefore, the design part of the vehicle uses very special software in designing the wire harness that plays a very important function in the vehicle, so that the wire is thinned, the contact reliability of the connector is improved, and the layout is rationalized. After creating the electric circuit diagram (electric circuit diagram), the parts of each part of the vehicle are designed, manufactured, tested, and maintained, and distributed to the process company and the process line to design and install the parts of each part according to the electric circuit diagram. To be determined.

However, post-process companies and process lines do not have the equipment and software to create and analyze electrical schematics.

Therefore, each company or process line that performs independent post-processing cannot check the short circuit or disconnection of the electric circuit distributed during the vehicle design and whether the control signal is normally transmitted or received. This could be confirmed only by checking the signal transmission and reception between the elements and the control elements.

If, after the process company and the process line to have the software and equipment to analyze and confirm the electrical schematics distributed in the design part, a problem that causes a huge expense occurs.

For the purpose of excluding such expensive expenses, an image file has been generated and provided for each circuit diagram. However, in this case, only a simple image inquiry about the connection relationship between circuits is possible. There is a problem that there is a great difficulty in tracking the signal information to be connected.

The present invention has been invented to solve the above problems, the object of which is to develop a vehicle, the purchase of a dedicated equipment and software for querying the electrical circuit diagram in a considerable number of related workers and partners and each workshop, etc. By eliminating the cost, it is possible to provide information on the electrical schematic analysis to reduce the manpower and time spent tracking signal connections and to prevent errors in signal tracking.

In addition, the designers of the actual electrical schematics can verify the design errors before distributing the designed electrical schematics, thereby providing the reliability of the electrical schematics distributed to each process line, partner companies, and repair shops. Support for Internet deployment of maintenance manuals and concurrent engineering with relevant teams and partners involved in vehicle development design is now possible.

1 shows the generation of an image file of an electrical circuit diagram for a vehicle according to the invention.

2 is a flowchart illustrating a process of generating an image file of an electric circuit diagram for a vehicle according to the present invention.

The present invention for realizing the above object comprises the steps of generating an electric circuit diagram for each part designed for the development vehicle as a general image file; Extracting each electrical schematic name from an image file, generating a coordinate list through analysis of signal input / output information in the circuit diagram, and generating a single file; Converting the generated coordinate list using a pre-defined standard coordinate file to extract a new coordinate system; Generating a table of contents file including a coordinate system by generating an index file using the electrical schematic name versus image file for each part; And linking the table of contents file with an image file having signal information to generate a viewable file capable of signal tracking and registering it in a database.

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

As can be seen in Figures 1 and 2, the electrical circuit diagramming system 10 generates, through a development software, a circuit diagram of each part designed for a vehicle currently being developed into a general dedicated image file that can be printed through a printer. To generate (S100).

In this case, the generated general dedicated image file includes information on a vehicle to be developed, a circuit diagram code, an Engineering Order (EO) ps name, and signal input / output.

Then, a list is generated by extracting coordinates (XY) of which component or connector in the circuit is located at which position in the circuit from information on signal input / output included in the general dedicated image file for each part. Signal input and output located in the coordinates generates a coordinate system file that contains information about which signals are generated in which circuit diagrams and which circuits are introduced (S200).

Thereafter, information on the signal input and output and coordinate information is included, and generates a script file containing information for generating a general image file (S300).

The reason for extracting and listing the coordinates (X, Y) from the image file in the above is that the coordinates of the standard coordinate file generated from the electrical schematic drawing system 10 and the image file generated by analyzing the signal input / output information are different. It is to convert as shown in the following example by applying the tolerance of the system.

Standard image file coordinates: X, Y

Generated image file coordinates: X + α, Y + β

This conversion of the coordinate system is recognized as the same coordinate system when creating a new image file, which enables signal tracking for the same position.

Subsequently, when the above series of operations are completed, a table of contents is generated as an index file from the extracted circuit diagram of each part, and selected to match the difference between the coordinate system of this file and the new image file. By using the standard coordinate file, a new coordinate system is inputted with a file having signal information and a circuit generated from an image to generate a signal traceable image file, that is, a searchable file (S400), to the database 20. It will register (S500).

Therefore, related teams and partners involved in the development of the target vehicle perform the analysis of the corresponding circuit diagram from the table of contents for the viewable files registered in the database 20 to perform signal tracking and circuit analysis of the distributed electric circuit diagram. To verify design errors.

As described above, according to the present invention, the information of the electric circuit diagram can be inquired and tracked through the Internet or a general PC without any additional software, so that the verification of the connection information on the electric circuit diagram of each process line and partner companies before the actual production of the vehicle This improves quality, reduces manpower and time spent on electrical schematic analysis, and eliminates expensive software purchases.
