[0042] In addition, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0043] It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the existence of the features declared thereafter, but does not exclude the addition of other features.

[0044] The electrical wiring interconnection system (EWIS) is a very important part of the aerospace product design process, which largely determines the safety, weight, performance, life and cost of aerospace products. In the design of EWIS, it is necessary not only to meet the coordination requirements and constraints of other disciplines such as overall, system, structure, etc., but also to involve multiple disciplines such as electrical, layout, structure, electromagnetic, and multiple departments such as design, manufacturing, and customer service. In the design process, it is necessary to compare, change and optimize a large number of design solutions based on the interconnection and mutual constraints between various systems, disciplines, and departments, taking into account hundreds of design variables, goals, and engineering constraints, and continuously coordinate and cycle the design to obtain the final solution.

[0045] EWIS design is mainly divided into functional design and physical design. Functional design drawings include electrical schematics, circuit diagrams / wiring tables, and circuit diagram equipment catalogs; physical design drawings include wiring harness installation drawings, wiring harness assembly drawings, and electrical equipment comprehensive installation drawings. At present, the mainstream 3D CAD system for aerospace products uses Dassault's CATIA, and the EWIS physical design involved in this article uses CATIA V5.

[0046] Given that the industry currently uses EWIS Design Zone (EDZ) for segmented design of aerospace products (such as aircraft), each EWIS design diagram of the electrical circuit of the entire aerospace product contains dozens of EWIS design zones. During the design process, each engineer designs one or several wire harnesses within the EWIS design zone. Taking the wire harness installation diagram as an example, each wire harness in an EDZ corresponds to a GBN wire harness assembly (geometric wire harness node, which refers to the geometric digital model of the wire harness assembly in a specific EDZ), and a GBN wire harness assembly contains all the parts of a certain wire harness in the EDZ.

[0047] In the design process of the existing EWIS design drawings, the EWIS design drawings of aerospace products are divided into dozens of EWIS design areas. The complete wire harness may need to cross several EWIS design areas, resulting in the complete wire harness being disconnected at the boundary of the EWIS design area. In the prior art, the assembly and connection of the EWIS design area is simply realized by engineers manually. First, the connection relationship between dozens of EWIS design areas needs to be determined. After placing dozens of EWIS design areas in appropriate positions according to the connection, since the wire harness has a margin at the boundary of the EWIS design area, the complete wire harness is still disconnected between adjacent EWIS design areas. Engineers are also required to manually connect the wire harnesses between the adjacent EWIS design areas to complete the assembly of dozens of EWIS design areas and obtain the EWIS design drawing.

[0048] Based on this, Figure 1 As shown, the present application provides a method for connecting an EWIS design area, the method comprising:

[0049] S101, responding to a connection request for an electrical wiring interconnection system EWIS for an aerospace product, obtaining a plurality of EWIS design areas matching the aerospace product, and determining a regional connection relationship between the plurality of EWIS design areas according to first-level connection configuration information of the EWIS design areas; the regional connection relationship includes a pairwise connection relationship among the plurality of EWIS design areas;

[0050] S102, determining a boundary connection relationship between connection boundaries of any two EWIS design areas having a region connection relationship according to the second-level connection configuration information of the EWIS design area, so as to determine a boundary connection relationship among a plurality of EWIS design areas;

[0051] S103, determining the wire bundle endpoint connection relationship between any two wire bundles at connection boundaries having a boundary connection relationship according to the third-level connection configuration information of the EWIS design area, so as to determine the wire bundle endpoint connection relationship in multiple EWIS design areas;

[0052] S104, connecting the multiple EWIS design areas according to the connection relationship of the wire harness endpoints in the multiple EWIS design areas.

[0053] The connection configuration information of multiple levels in the connection method is pre-stored in a database. The connection configuration information of multiple levels includes first-level connection configuration information, second-level connection configuration information and third-level connection configuration information of multiple EWIS design areas.

[0054] Specifically, in the embodiment of the present application, the first-level connection configuration information and the second-level connection configuration information of the EWIS design area are determined according to the electrical circuit characteristics of the aerospace product;

[0055] The third level connection configuration information of the EWIS design area is determined based on the location information of the electrical circuits of the aerospace product.

[0056] In the step S101, the response to the connection request for the electrical wiring interconnection system EWIS of the aerospace product obtains multiple EWIS design areas matching the aerospace product. Specifically, the multiple EWIS design areas are loaded in the EWIS design software (such as CATIA V5), and the GBN harness components of the multiple EWIS design areas are expanded.

[0057] Exemplarily, in order to clearly illustrate the connection method described in the embodiment of the present application, it is assumed that the multiple EWIS design areas are 10 EWIS design areas, and these 10 EWIS design areas are EWIS design area 1, EWIS design area 2, ... EWIS design area 10.

[0058] The user, i.e., the design engineer of the EWIS design area, designs the EWIS design area in the EWIS design software (e.g., CATIA V5), and determines the pairwise connection relationship between multiple EWIS design areas based on the electrical circuit characteristics of the aerospace product to ensure the continuity of the same wire harness passing through different EWIS design areas.

[0059] Exemplarily, the pairwise connection relationship between the multiple EWIS design areas, for example: EWIS design area 1 is connected to EWIS design area 2 in pairs, and EWIS design area 2 is connected to EWIS design area 3 in pairs.

[0060] If two EWIS design areas are adjacent in position, but according to the electrical circuit characteristics of aerospace products, there is no partial wiring harness of the same wiring harness between the two EWIS design areas, then the two EWIS design areas do not belong to the regional connection relationship configured in the first-level connection configuration information.

[0061] According to the first-level connection configuration information of the EWIS design area, the regional connection relationship between multiple EWIS design areas is determined. For example, for the EWIS design area 1, according to the first-level connection configuration information, from the 10 EWIS design areas, EWIS design area 2 connected to the EWIS design area 1 in pairs and EWIS design area 3 connected to the EWIS design area 1 in pairs are determined; then EWIS design area 4 and EWIS design area 5 connected to EWIS design area 2 in pairs are determined; and so on, the regional connection relationship between the 10 EWIS design areas is determined.

[0062] In the step S102, the second-level connection configuration information is used to characterize which two connection boundaries have a boundary connection relationship among any two EWIS design areas that have a region connection relationship.

[0063] For example, EWIS design area 1 is connected to EWIS design area 2 and EWIS design area 3. EWIS design area 1 has two connection boundaries, namely connection boundary 1A and connection boundary 1B; EWIS design area 2 has two connection boundaries, namely connection boundary 2A and connection boundary 2B; EWIS design area 3 has three connection boundaries, namely connection boundary 3A, connection boundary 3B, and connection boundary 3C.

[0064] According to the second-level connection configuration information of the EWIS design area, it is determined that there is a boundary connection relationship between the connection boundary 1A of the EWIS design area 1 and the connection boundary 2A of the EWIS design area 2; there is a boundary connection relationship between the connection boundary 1B of the EWIS design area 1 and the connection boundary 3B of the EWIS design area 3; and so on, according to the second-level connection configuration information, the boundary connection relationship between the connection boundaries of multiple EWIS design areas is determined.

[0065] In the step S103, for any two wiring harnesses at connection boundaries having a boundary connection relationship, for example, there are 5 wiring harnesses at connection boundary 1A of the EWIS design area 1 and there are 5 wiring harnesses at connection boundary 2A of the EWIS design area 2, then according to the third-level connection configuration information of the EWIS design area, it is determined which wiring harness at connection boundary 2A of the EWIS design area 2 each wiring harness at connection boundary 1A of the EWIS design area 1 needs to be connected to, so as to connect the segments of the same wiring harness in different EWIS design areas.

[0066] When the user uses the EWIS design software to assemble the multiple EWIS design areas, after the step S102 is performed based on the boundary connection relationship between the multiple EWIS design areas, the positions of the multiple EWIS design areas can be determined, and the EWIS design areas with boundary connection relationships are placed in mutually adjacent positions. For example, the connection boundary 1A of the EWIS design area 1 and the connection boundary 2A of the EWIS design area 2 are adjacent.

[0067] The process of determining the positions of the multiple EWIS design areas may be implemented automatically or semi-automatically. The automatic implementation is that, for the first target EWIS design area, after determining the second target EWIS design area having a boundary connection relationship with the first target EWIS design area, the second target EWIS design area is placed at a position adjacent to the first target EWIS design area according to the position of the first target EWIS design area in the design interface of the EWIS design software, the identification information of the connection boundary of the first target EWIS design area, and the identification information of the connection boundary of the second target EWIS design area.

[0068] The semi-automatic implementation is, that is, for the first target EWIS design area, after determining the second target EWIS design area that has a boundary connection relationship with the first target EWIS design area, the boundary connection relationship between the first target EWIS design area and the second target EWIS design area is displayed to the user; in response to the user's movement operation on the second target EWIS design area, the second target EWIS design area is placed at a position adjacent to the first target EWIS design area.

[0069] The display of the boundary connection relationship between the first target EWIS design area and the second target EWIS design area to the user may be achieved by arrow indication, box selection, etc.

[0070] Specifically, in the embodiment of the present application, the third-level connection configuration information of the EWIS design area includes: the coordinate information of the wire bundle endpoints of the wire bundle at the connection boundary of each EWIS design area, and the tangent direction information of the wire bundle at the wire bundle endpoints;

[0071] In step S104, the multiple EWIS design areas are connected according to the connection relationship of the wire harness endpoints in the multiple EWIS design areas, that is, after placing all the EWIS design areas with boundary connection relationships in the multiple EWIS design areas to the correct positions, the wire harness endpoints at the connection boundaries of any two EWIS design areas with boundary relationships are connected. Exemplarily, the 5 wire harnesses at the connection boundary 1A of the EWIS design area 1 and the 5 wire harnesses at the connection boundary 2A of the EWIS design area 2 are connected respectively, each wire harness at the connection boundary 1B of the EWIS design area 1 is connected to each wire harness at the connection boundary 3B of the EWIS design area 3, and then the wire harnesses at the connection boundaries of the EWIS design area 2 and the EWIS design area 4 and the EWIS design area 5 are connected respectively.

[0072] The method for connecting EWIS design areas described in the present application pre-stores configuration information of multiple levels of multiple EWIS design areas of the aerospace product. When dealing with multiple EWIS design areas, the method determines the regional connection relationship between the multiple EWIS design areas connected in pairs, the boundary connection relationship between the connection boundaries of any two EWIS design areas with a regional connection relationship, and the wire harness endpoint connection relationship between the wire harnesses at any two connection boundaries with a boundary connection relationship. The multiple EWIS design areas are connected according to the wire harness endpoint connection relationship in the multiple EWIS design areas to connect the multiple EWIS design areas and complete the EWIS design drawing of the aerospace product. During the connection process, the user does not need to determine the regional connection relationship and the boundary connection relationship by himself, nor does the user need to manually connect the same wire harness that is disconnected in different EWIS design areas, thereby realizing the automatic connection of the wire harness at the boundary of the EWIS design area, saving time and energy in the design process of the EWIS design drawing.

[0073] Taking aircraft as an example, the current mainstream aircraft model design divides the EWIS system into main areas and sub-areas. The main area is divided into the nose, equipment compartment, passenger cabin, engine and pylon, tail and tail section, cargo compartment, wing and landing gear. There are several sub-areas under each main area.

[0074] Based on this, the connection method of the EWIS design area described in the embodiment of the present application also includes:

[0075] Determining the EWIS design areas included in each group according to group configuration information of the plurality of EWIS design areas; the group configuration information is determined according to structural features of the aerospace product;

[0076] like Figure 2As shown, the connecting of the multiple EWIS design areas according to the connection relationship of the wire harness endpoints in the multiple EWIS design areas includes:

[0077] S201, based on the group configuration information, respectively connecting the EWIS design areas in each group according to the endpoint connection relationship in each group to obtain a plurality of sub-design areas;

[0078] S202. Determine the wiring harness endpoint connection relationship between the multiple sub-design areas through the connection configuration information of the multiple levels, and connect the multiple sub-design areas according to the wiring harness endpoint connection relationship between the multiple sub-design areas to obtain the EWIS design drawing of the aerospace product.

[0079] The group configuration information is pre-stored in the database. Exemplarily, at least one EWIS design area corresponding to the nose, equipment compartment, passenger cabin, engine and pylon, tail wing and tail section, cargo compartment, wing and landing gear of the aircraft is taken as a group, and the group configuration information of the multiple EWIS design areas is determined.

[0080] The connection relationship between the wire harness endpoints between the sub-design areas may be determined by the connection relationship between the wire harness endpoints of the EWIS design area at the boundary of the sub-design area.

[0081] Specifically, the connection relationship between the wire harness endpoints between the sub-design areas is determined in the following manner:

[0082] Determine, according to the first-level connection configuration information of the EWIS design area, a target EWIS design area having a regional connection relationship with the EWIS design area at the boundary of the first target sub-design area, and determine that the sub-design area where the target EWIS design area is located is a second target sub-design area, and the second target sub-design area has a regional connection relationship with the first target sub-design area;

[0083] Determine, according to the second-level connection configuration information of the EWIS design area, a boundary connection relationship between the EWIS design area at the boundary of the first target sub-design area and the EWIS design area at the boundary of the second target sub-design area;

[0084] According to the third-level connection configuration information of the EWIS design area, a wire bundle endpoint connection relationship between a wire bundle at an EWIS design area boundary at a first target sub-design area boundary and a wire bundle at an EWIS design area boundary at a second target sub-design area boundary is determined.

[0085] According to the structural characteristics of the aerospace product, the present application divides the multiple EWIS design areas into multiple groups to realize parallel assembly of multiple groups of EWIS design areas, further saving assembly time. At the same time, sub-design area maps of each sub-area of ​​the aerospace product can also be obtained, making the EWIS design area assembly process more flexible.

[0086] Since the wiring harness in the EWIS design drawing corresponds to the aerospace product, the third-level connection configuration information of the EWIS design area determined according to the location information of the electrical circuit of the aerospace product specifically includes: the wiring harness endpoint coordinate information of the wiring harness at the connection boundary of each EWIS design area, and the tangent direction information of the wiring harness at the wiring harness endpoint;

[0087] The same wire harness needs to ensure continuity when crossing multiple EDZs, that is, each wire harness segment has the same position at the EDZ interface, opposite directions, and the diameters must be consistent. Therefore, the multiple EWIS design areas are connected according to the connection relationship of the wire harness endpoints in the multiple EWIS design areas, including:

[0088] According to the harness endpoint connection relationship, the harness endpoint coordinate information, and the tangent direction information of the harness at the harness endpoint, a smooth connection line is generated between two harnesses having a harness endpoint connection relationship according to a preset connection rule to connect the multiple EWIS design areas.

[0089] Specifically, the connection relationship of the wire harness endpoints in the multiple EWIS design areas, that is, the coordinate information of the wire harness endpoints is the same.

[0090] A smooth connection line is generated between two wire harnesses having a connection relationship between the wire harness endpoints according to a preset connection rule, that is, a smooth connection line is generated between two wire harnesses having the same wire harness endpoint coordinate information according to the preset connection rule.

[0091] The method of generating a smooth connection line between two wire harnesses having a connection relationship between wire harness endpoints according to a preset connection rule specifically includes: after determining the two wire harnesses having a connection relationship between wire harness endpoints, extending from the wire harness endpoint of one wire harness to the wire harness endpoint of another wire harness in a second-order continuous (derivative continuous) manner of a spline curve to generate a smooth connection line between the two wire harnesses and maintain the continuity of the two wire harnesses.

[0092] In an embodiment of the present application, the connection method of the EWIS design area also includes: when the smoothness of the target wire bundle formed by the two wire bundles and the connecting line does not meet the smoothness condition, adjusting the connecting line so that the two wire bundles are smoothly connected to the connecting line.

[0093] The adjusting of the connection line includes flipping the tangent direction of the wire harness at the wire harness endpoint and regenerating a smooth connection line between the two wire harnesses having the wire harness endpoint connection relationship.

[0094] Flipping the tangent direction of the harness at the endpoints of the harness is to solve the problem that when automatically calculating the continuity of the spline curve, a connecting line may be generated according to the opposite directions of the tangent directions of the two end points at the EDZ boundary, and a smooth connection is not achieved between the two harnesses.

[0095] The user can manually identify whether a smooth connection is achieved between the two harnesses.

[0096] In an embodiment of the present application, the method for connecting the EWIS design areas, after connecting the multiple EWIS design areas according to the connection relationship of the wire harness endpoints in the multiple EWIS design areas, the method for connecting the EWIS design areas further includes:

[0097] In response to a disconnection request for the two connected EWIS design areas, disconnecting the connection between the two connected EWIS design areas.

[0098] The purpose of disconnecting the connection between the two connected EWIS design areas is to enable the user to roll back to the initial state where the harness is not connected in case of a design error in the EWIS design area, modify the disconnected EWIS design area, and manually or automatically connect the harness boundaries for the modified EWIS design area.

[0099] Taking an aircraft as an example, there are dozens of EDZs in the EWIS diagram of the entire aircraft, and nearly 10,000 disconnected wire harnesses. Due to the huge amount of data, the relationship database technology can be used to solve the matching problem of wire harnesses under different EDZs at the boundary. Therefore, the connection configuration information of the multiple levels is stored in the background database.

[0100] Since the amount of data in the connection method described in the embodiment of the present application is huge, in order to reduce the time complexity of a large number of background traversals, the EWIS design areas connected in pairs are divided into a main EWIS design area and a slave EWIS design area.

[0101] Based on this, the connection method of the EWIS design area includes in the first-level connection configuration information of the EWIS design area: a main identifier carried by each EWIS design area, and slave identifiers carried by other EWIS design areas that match each main identifier and are connected to the EWIS design area carrying the main identifier; wherein different EWIS design areas carry different main identifiers, and different main identifiers match different slave identifiers;

[0102] like Figure 3As shown, according to the first-level connection configuration information of the EWIS design area, the regional connection relationship between multiple EWIS design areas is determined, including:

[0103] S301, based on the primary identifier of the first-level connection configuration information of the EWIS design area, traverse multiple EWIS design areas to determine at least one EWIS design area carrying a secondary identifier matching the primary identifier;

[0104] S302: According to the first-level connection configuration information, determine the area connection relationship between the EWIS design area carrying the master identifier and each EWIS design area carrying the slave identifier.

[0105] Exemplarily, the EWIS design area 1 has a regional connection relationship with the EWIS design area 2 and the EWIS design area 3 respectively; the EWIS design area 1 carries a master identifier 1 master, and the EWIS design area 2 and the EWIS design area 3 respectively carry a slave identifier 1 slave; during the background traversal, only one traversal is performed on multiple EWIS design areas to determine the EWIS design area 2 and the EWIS design area 3 carrying the slave identifier 1 slave, and then the EWIS design area 2 and the EWIS design area 3 are distinguished, and the regional connection relationship between the EWIS design area 2 and the EWIS design area 1, and the regional connection relationship between the EWIS design area 3 and the EWIS design area 1 are determined; based on this, there is no need to traverse the multiple EWIS design areas multiple times, which reduces the time complexity of a large number of background traversals.

[0106] Different EWIS design areas carry different main identifiers, and different main identifiers match different slave identifiers. For example, the EWIS design area 1 carries the main identifier 1 master, and the EWIS design area 2 and the EWIS design area 3 carry the slave identifier 1 slave respectively, and the main identifier 1 master matches the slave identifier 1 slave; the EWIS design area 2 carries the main identifier 2 master, and the EWIS design area 4 and the EWIS design area 5 carry the slave identifier 2 slave respectively, and the main identifier 2 master matches the slave identifier 2 slave.

[0107] The connection method of the EWIS design area described in the present application corresponds to a connection system when it is specifically implemented. The connection system includes a server and a terminal. The EWIS design software runs on the terminal. The server is used to store the EWIS design area and the connection configuration information of the multiple levels.

[0108] Specifically, the server side uses Java web (Servlet) and Oracle database, and the terminal runs an automated modeling tool for CATIA secondary development. Since the underlying layer of CATIA secondary development uses C++ language and the integration with the database is relatively complex, Web Socket is finally used to access the server-side Java page to facilitate the reading and writing operations of the database.

[0109] The connection system has multiple functions such as user login, creation of boundary information, wiring harness connection, display of boundary information and deletion of boundary information.

[0110] The user logs into the connection system, loads a plurality of EWIS design areas in a harness installation diagram, and expands the GBN harness components in the EWIS design areas.

[0111] The creation of boundary information includes establishing a database based on the loaded EWIS design area. Specifically, the user selects any wire harness in the loaded wire harness installation diagram, the wire harness endpoint of the wire harness is the master end or the slave end, and sets the master identifier or the slave identifier of the EWIS design area where the wire harness is located; the user determines the regional connection relationship and boundary connection relationship between multiple EWIS design areas according to the electrical circuit characteristics of the aerospace product, thereby determining the first-level connection configuration information and the second-level connection configuration information of the EWIS design area; the access system can automatically identify the wire harness endpoint coordinates of the wire harness and the curve tangent direction of the wire harness at the wire harness endpoint, and use the wire harness endpoint coordinate information and the tangent direction information of the wire harness at the wire harness endpoint as the third-level connection configuration information of the EWIS design area; the first-level connection configuration information, the second-level connection configuration information and the third-level connection configuration information of the EWIS design area are stored in the database;

[0112] Specifically, for the first-level connection configuration information and the second-level connection configuration information of the EWIS design area, a geometric graphics set under the CATIA part structure tree can be automatically created through the access system, and the relevant information is attached to the geometric graphics set in the form of parameters, and all relevant information is recorded in the database.

[0113] The creating boundary information specifically includes connecting connection boundaries between two EWIS design areas having a boundary connection relationship, disconnecting two already connected EWIS design areas, and adjusting a connection line between two wire harnesses smoothly connected by a connection line.

[0114] The wire harness connection function is that the user connects two wire harnesses with a wire harness endpoint connection relationship according to the wire harness endpoint connection relationship in the two EWIS design areas with a boundary connection relationship, so as to realize the connection of the wire harness boundaries of the EWIS design areas.

[0115] The display boundary information can display the wiring harnesses under some or all EWIS design areas, as well as the first-level connection configuration information, second-level connection configuration information, third-level connection configuration information, grouping configuration information and other related information corresponding to all EWIS design areas, and export the related information to an excel spreadsheet.

[0116] Deleting the boundary information means deleting certain information in the database. If the deleted information is attached to the geometric graphics set in the form of parameters, the geometric graphics set will be deleted at the same time to ensure the integrity and consistency of the data.
