Japanese Patent Laid-Open No. 11-085811 (FIG. 1)

  In the design of harnesses for individual products such as artificial satellites, the prototype process prior to mass production is omitted, and the harness shape is designed directly into the 3D model, without using the harness as a component or as a single unit. Although it is necessary to extract all the information and connect it to manufacturing, in the conventional method, it was necessary to make a harness component and to measure and input the line length in some form, which is inefficient work. It was. Even if a three-dimensional model is used, logical connection information cannot be held in the shape drawn in the mechanism drawing, and from where to where the connection corresponding to the connection diagram is connected from that model. Since the information could not be obtained directly, there is no way to check the wiring route during the design, other than reading the connection diagram created by the designer and the number map assigned to each branch of the wiring.

The present invention also relates to a method for creating a kitting list and wire specification labels based on a set work procedure.

Embodiment 1 FIG.
FIG. 1 is a diagram showing the configuration of the wiring work instruction apparatus according to the first embodiment, where 1 is a device layout drawing storage unit, 2 is an electronic wire list storage unit, 3 is a design data reading unit, and 4 is a harness wiring model creation unit. Reference numeral 5 denotes a harness wiring model display unit, 6 denotes a work procedure creation unit, 7 denotes a work procedure display unit, 8 denotes a kitting list and wire specification label creation unit, and 9 denotes an output device.

  The wiring layout model and the design data reading unit 3 in the procedure creation device read the device layout drawing showing the layout of parts, the wiring route of the wire harness, etc., store it in the device layout drawing storage unit 1 and assign the connector pin. The electronic wire list in which information and route classification are listed is read and stored in the electronic wire list storage unit 2.

  A harness wiring model creating unit 4 creates a harness wiring model based on the information on the device layout drawing stored in the device layout drawing storage unit 1 and the information on the electronic wire list stored in the electronic wire list storage unit 2. Displayed on the wiring model display unit 5.

  The work procedure creation unit 6 automatically creates a work procedure for performing terminal processing of the specifications representing the destination and destination of wiring, connector wiring, and wiring work. The work procedure creation unit 6 creates the work procedure. The work procedure is displayed on the work procedure display unit 7.

  Based on the work procedure created by the work procedure creation unit 6, the kitting list and wire specification label creation unit 8 generates a kitting list for performing line cutting work and a wire specification label describing destination-destination information. The data is transferred and output through the output device 9 for printing the kitting list, the wire specification label, and the like on paper.

  FIG. 2 is a diagram showing details of the harness wiring model creation unit of the wiring work instruction apparatus according to the first embodiment, where 10 is a route classification symbol, 11 is a wire database, 12 is a conversion program, 13 is a harness wiring model, and 14 is Route information, 15 is wire length information, 16 is a harness wiring model mass property, 17 is a mass property for each wire, 18 is wire arrangement data, 1, 2 and 4 are the same as in FIG.

  The designer refers to the pin assignment information of the connector attached to each device, and displays information on which connector pin is connected to the signal output from that connector pin to the other device. An electronic wire list is created electronically.

  At this time, a specific wiring route of the harness has not yet been determined in the electronic wire list stored in the electronic wire list storage unit 2, but a route different from other wiring routes is required due to characteristics. Gives a route classification symbol 10 for determining the wiring route.

For example, the route classification symbol 10 is given as PWR if this connection is a power line, and SIG if it is a signal line.
This flag does not indicate a specific route, but is merely a flag for identification. Then, when the designer fills up so far, the design data reading unit 3 stores the connection relationship between the destination and the destination and the route classification symbol 10 in the electronic wire list storage unit 2 as an electronic wire list, Transmit to the harness wiring model creation unit 4.

  The harness wiring model creation unit 4 converts the electronic wire list into the connection relation between the destination and the destination and the route classification via the conversion program 12 based on the electronic wire list including the connection relation between the destination and the destination and the route classification received from the designer. According to the connector-to-connector list, the harness wiring model 13 is automatically generated on the device layout drawing.

The automatic generation function itself is automatically performed by using a standard automatic routing function for the three-dimensional CAD, and thus description thereof is omitted here. Hereinafter, the work of converting into a connector-to-connector list according to the connection relationship between the destination and the destination and the route classification is called grouping.
A method of grouping electronic wire lists will be described with reference to FIG.

  Usually, a device such as an artificial satellite uses a connector having 50 to 100 pins, and by performing grouping, the number of connections of the connector-to-connector is approximately 1/10 compared to the number of connections of the pin-to-pin. .

  By implementing wiring using the grouped electronic wire list at the same time, the actual number of connections is reduced to 1/10, while the wire diameter is about 10 times. Alternatively, creation of a large-scale harness wiring model 13 that cannot be displayed due to the relative relationship between a satellite body of several meters and a harness wire diameter of several millimeters can be realized on the device layout diagram.

  In addition, regarding the wire diameter of the harness wiring model 13 when performing wiring, the diameter information for each wire is read from the wire database 11 prepared separately based on the wire before grouping on the conversion program 12 for grouping. The bundled wire diameter after grouping is automatically calculated.

  The harness wiring model 13 in which wiring is performed using the grouped electronic wire list by the above method has logical connection information indicating which connector is connected to which connector on the model. It becomes possible to acquire the correct line length information 15 from the harness wiring model 13.

  In addition, since the model itself holds the diameter of the bundled state, it is necessary to grasp the necessary space at each wiring position and check on the harness wiring model 13 for interference with each device arranged there. Is also possible.

  Further, since the wire length information 15 representing the length of the wire is acquired with the logical connection information on the harness wiring model 13, the mass property information 16 such as the exact weight and the center of gravity of the entire harness, Similarly, mass property information 17 such as accurate weight and center of gravity of one wire can be calculated in advance with accuracy of several percent error.

  In design review and harness production, the harness wiring model 13 and the electronic wire list are matched to immediately refer to the wiring path 14 from one connector pin position to one connector pin position from the harness wiring model 13. Is possible.

  The line length information 15 acquired from the harness wiring model 13 can be reflected in the original electronic wire list via the grouped electronic wire list.

  From the above, the electronic wire list can be used as the wire arrangement data 18 and the kitting list at the manufacturing site, and the work that has been conventionally adjusted by combining can be greatly reduced.

Embodiment 2. FIG.
FIG. 3 is a diagram illustrating a three-dimensional display model by the harness wiring model creation unit of the wiring work instruction apparatus according to the second embodiment, in which 19 is a device A, 20 is a device B, and 21 is a device C.

  FIG. 3 is an example of an image representing a real thing used in the present invention in three dimensions, and an image represented by a three-dimensional display model is as shown in FIG. 3, and devices such as device A19, device B20, and device C21 are three-dimensional. The devices A19 are attached with connectors numbered CON1 and CON2, and the device B20 is attached with connectors numbered CON3 and CON4.

  As described above, a display representing wiring between connectors attached to a three-dimensionally displayed device is performed. In particular, the selected wiring is displayed in a color display that is easier to see than other displays. The route of the target wiring is displayed so as to be clear.

  FIG. 4 is a diagram for explaining a method of grouping electronic wire lists by the harness wiring model creation unit of the wiring work instruction apparatus according to the second embodiment, wherein 22 is a destination connector, 23 is a destination pin, 24 is a route classification, 25 Is a destination connector, 26 is a destination pin, 27 is a wire diameter, 28 is a first group, 29 is a second group, 30 is a third group, 31 is a fourth group, 32 is a fifth group, Reference numerals 19 to 21 are the same as those in FIG.

A description will be given of an algorithm for grouping an electronic wire list including a connection relation between a wire destination and a destination and a route section.
In FIG. 4, A is a state before grouping, all connection information and its route classification are added if necessary, and B is a state after grouping, from the same destination connector to the same destination The wire diameter is obtained by grouping the connections connected to the connector.

  For example, when the target work to be performed for the wiring of the harness is a device in which three devices A19, B20, and C21 are arranged, connectors numbered CON1 and CON2 are attached to the device A19. It is assumed that connectors numbered CON3 and CON4 are attached to the device B20, and the device C21 is a device having no connector.

  In the column of the destination connector 22, the connector numbers attached to the devices A19, B20, and C21 are entered. In the column of the destination pin 23, the pin number in the connector number is entered. In the column of, special items regarding the wiring path are described. In the column of the destination connector 25, connector numbers attached to the wiring destination devices A19, B20, and C21 are entered. The destination pin number is described, and the information corresponding to the outer diameter proportional to the number of wires is described in the column of the wire diameter 27.

  The first group 28 is a group in which the column of the destination connector 22 is represented by CON1 and the column of the destination connector 25 is represented by CON3, and the second group 29 is represented by the column CON1 of the destination connector 22 and the column of the destination connector 25 by CON2. The third group 30 is a group in which the column of the destination connector 22 is represented by CON2 and the column of the destination connector 25 is represented by CON3, and the fourth group 31 is a column of the destination connector 22 and CON2 and the column of the destination connector 25. The fifth group 32 is a group in which the column of the destination connector 22 is CON2, the column of the destination connector 25 is CON4, and the column of the route section 24 is expressed by SIG.

  For example, what is represented by the first group 28 is that the four lines connected from the connector CON1 of the device A19 to the connector CON3 of the device C21 have the same connection for each connector. If each wire diameter is assumed to be 1, the wire diameter is calculated as 4 in the column of wire diameter 27 and described.

  In this way, the symbols described in the plurality of route sections 24 are also entered in the connection from CON1 described in the same destination connector 22 to CON3 described in the same destination connector 25. Grouping is performed according to symbols such as SIG described in the column of the route classification 24.

  For example, five lines are connected from CON2 described in the connector 22 column to CON4 described in the destination connector 25 column, but SIG is displayed in the route segment 24 column on the electronic wire list. Therefore, it is divided into two types of connections, one consisting of three lines not listed in the route classification 24 column and the other consisting of two lines labeled SIG in the route classification 24 column. A wire diameter 27 is calculated for each section 24.

FIG. 5 is a diagram showing a procedure setting flow of harness wiring work by the wiring procedure creation method of the wiring work instruction apparatus according to the second embodiment.
This procedure is performed using the work procedure creation unit 6 of the wiring work instruction apparatus, and will be described in detail below.

  First, when the electronic wire list exists only for each connector in the direction from the destination to the destination, it is also created for the direction from the destination in the opposite direction to the destination, so that all the connectors exist on the destination side and the destination side. Data creation is performed (ST1).

Next, the electronic wire list is rearranged for each connector, and the wires are arranged in descending order (ST2), and the destination connector having the largest number of wires is set as the wiring procedure 1 (ST3).
In the wiring procedure 1, when there are a plurality of destination connectors (ST4), rearrangement is performed in descending order of the number of wires of the destination connector, and the procedure starts from the one with the largest number of wires of the destination connector (ST5).

Next, except for the wire where the destination-destination is organized and the procedure is determined (ST6), similarly, the destination connector is arranged in the order of the number of wires, and the one with the largest number of wires at that time is set as the specification on the destination side, The destination-destination is organized, and this destination-destination operation is defined as wiring procedure 2.
This is repeated in the same manner until there is no remaining wire, and a wiring procedure is set (ST7).

Next, a kitting list is created for each destination connector based on the procedure.
In the kitting list creation method, the line type for each destination connector and the number of wires for each line length of the determined procedure are calculated, and are arranged and displayed for each line type and line length.

Next, based on the procedure, a wire specification label describing destination-destination information is created.
The wire specification label creation method displays the destination-destination pin number for each destination-destination specification number of the determined procedure.

  When using a kitted wire in actual work, the kitting list is created based on the procedure in the actual work, so it can be used in the order in which it was kitted. And effective work is possible.

  In actual work, when sticking the wire specification label to the wire, the wire specification label is created based on the procedure in the actual work, so it can be used in the displayed order, and confirmation of work mistakes Therefore, it is possible to perform an effective work.

Embodiment 3 FIG.
FIG. 6 is a diagram showing a wiring work flow according to the wiring work method of the wiring work instruction apparatus of the third embodiment.
The work of preparing and checking the kitting list printed from the output device 9 of the wiring work instruction apparatus of the present invention (ST11) and the work of preparing and checking the wire specification label (ST12) are performed.
The operator performs the wire cutting operation (ST13) in the order of the kitting list prepared in ST11, and prepares the wire.

When the wire cutting operation (ST13) is completed, the terminal processing on the destination side and the connector wiring are performed based on the operation procedure (ST14).
Here, since the kitted wires are created based on the work procedure, they may be performed in the order of the kitting list 11.

Next, the wire specification label is attached to the wire in accordance with the destination-destination (ST15).
In the wire specification label affixing operation (ST15), since the wire specification labels are created based on the work procedure, the wire specification labels may be applied in the order in which the wire specification labels are displayed.

  Next, wiring and bundling work (ST16) is performed for each wire destination, terminal processing on the destination side of the connector and connector wiring (ST17) are performed, and all wiring work is completed.

  In order to reflect thousands to tens of thousands of large-scale harness models one by one on a three-dimensional model, it is not possible to model a wire with a diameter of several millimeters for a hardware limit or an overall drawing of several meters. However, it was possible to create a harness wiring model and use the harness wiring model to instruct wiring.

  Since the shape drawn on the 3D model does not have logical connection information, it can be used for arrangements, pre-cutting of wire rods, creation of kitting lists, and mass property information such as weight / center of gravity. Compared with the connection diagram on the map, the line length between addresses was manually measured on the scale at the on-site work, and each was tabulated, so the line length measurement work was inefficient and a large error occurred. However, the use of the harness wiring model has the effect that it is not necessary to arrange extra wires.

In order to change the automatically created work procedure, it is possible to perform manual rearrangement while checking the work procedure display unit 7 (ST4).
In that case, all the destination-destination specifications will be rearranged as the destination-destination changes.

  As a method of setting work procedures, not only the order of the number of wires when organizing destinations and destinations but also, for example, a method that uses one destination-destination (one with no multiple destinations) is used. The method is not limited to this, for example, in the order of the number of destination specifications when organizing destination-destination.

  The arrangement order of the kitting list is not limited to this, for example, a method of arranging for each line length for each type of wire as well as for each line length for each destination specification.

  In the arrangement order of the wire specification labels, not only the destination-destination is displayed for each destination specification, but also the method of displaying only the destination in the order of each destination specification, for example, the method of displaying in the order of wire numbers, etc. This is not the case.
