[Inspection method of wiring diagram data]
Next, an inspection method for wiring diagram data will be described with reference to FIG.

  In step S11, the connection unit 21 creates primary wiring information. In step S11, first, the connection unit 21 refers to the wiring harness identifiers included in all the wiring diagram data of the first model and all the wiring diagram data of the second model for each of the wiring areas 11 to 13. Harness information of the next wire harness is extracted. In this extraction, the harness information of the wire harnesses X1, X2, Y1, Y2, Z1, Z2 existing in both the first model and the second model, and the wire harness X3 existing in one of the first model or the second model, The harness information of Y3 and Z3 is extracted. The upper diagram in FIG. 5 shows all wire harnesses from which harness information has been extracted. Then, based on the terminal information and the connection destination information included in all the extracted harness information, all the connection terminals connected to each other are associated with each other, and all formed by the connection of the wire harness between the plurality of wiring diagram data Primary wiring information representing the conduction path is created. As shown in FIG. 5, each conduction path is connected to a wire harness between adjacent wiring areas 11 to 13. The primary wiring information is stored in the memory. The primary wiring information represents a virtual wiring diagram and is not plotted on the computer.

  With reference to FIG. 5, the connection destination search performed when associating the connection terminals connected to each other in step S11 will be described. The connection destination search is performed for each connection terminal.

  In the connection destination search of the connection terminal x21 of the wire harness X1 in the first wiring area 11, the connection destination information associated with the connection terminal x21 is used, and the connection terminal y11 to which this connection destination information is assigned is the second. The connection terminals in the wiring area 12 are searched. And connection terminal x21 and connection terminal y11 are matched. Furthermore, in the connection destination search of the connection terminal y21 of the wire harness Y1 in the second wiring area 12, the connection destination information associated with the connection terminal y21 is used, and the connection terminal z11 to which this connection destination information is assigned is Search is made from the connection terminals of the third wiring area 13. And connection terminal y21 and connection terminal z11 are matched. Thereby, as shown in the middle figure (primary wiring information) of FIG. 5, the information of the conduction | electrical_connection path | route with which wire harness X1, wire harness Y1, and wire harness Z1 were connected is produced. Similarly, information on a conduction path in which the wire harness X2, the wire harness Y2, and the wire harness Z2 are connected is created. Information of a conduction path in which the wire harness X3, the wire harness Y3, and the wire harness Z3 are connected is created. The primary wiring information is constituted by the information of these conduction paths.

  Subsequently, in step S12, the deletion unit 22 acquires harness list information from the memory.

  Subsequently, in step S <b> 13, the deletion unit 22 acquires one model information from the harness list information. In step S13 for the first time, information representing the first model is acquired as model information. In step S13, which is performed after step S17 described later, information representing the second model is acquired as model information.

  Subsequently, in step S14, the deletion unit 22 creates secondary wiring data using the harness combination information corresponding to the model information acquired in step S13. In the first step S14, the harness combination information of the first model included in the harness list information is used. Also, a copy of the primary wiring information is created in the memory. Then, based on the harness combination information of the first model, the information on the conduction path including the wire harness not included in the harness combination information of the first model is deleted from the information of the conduction path included in the primary wiring information. . In the lower diagram of FIG. 5, information on conduction paths (X3, Y3, Z3) not included in the inspection target is deleted. Thereby, secondary wiring information corresponding to the first model is created. In FIG. 5, the dotted line represents the deleted conduction path. Similar to the primary wiring information, the secondary wiring information represents a virtual wiring diagram and is not illustrated on the computer.

  Subsequently, in step S15, the inspection unit 23 acquires all the wiring specification information of the first model from the memory.

  Subsequently, in step S16, the inspection unit 23 inspects the secondary wiring information created in step S14. In step S16, information indicating the conduction path (hereinafter referred to as “comparison target path”) included in each wiring specification information acquired in step S15, and the conduction path included in the secondary wiring information (hereinafter referred to as “inspection target path”). Based on the comparison with the information indicating ")", the connection error of the wire harness in the secondary wiring information is inspected. The connection destination information associated with each connection terminal of the inspection target path is compared with the terminal information of each connection terminal of the comparison target path, and the connection error of the wire harness is inspected. When the connection destination information associated with each connection terminal of the inspection target path matches the terminal information of each connection terminal of the comparison target path, it is determined that there is no error in the connection of the wire harness. In the inspection target path described in FIG. 6, the connection destination information L1 and R1 associated with the connection terminals x11 and z21 matches the terminal information L1 and R1 of each connection terminal of the comparison target path. It is determined that there is no connection error in the wire harness.

  Subsequently, in step S17, the wiring inspection device 20 determines whether or not there is model information in the wiring harness list that has not been subjected to the inspection of the wiring diagram data. If there is model information whose wiring diagram data has not been inspected, the process returns to step S13. In the first step S17, it is determined that there is a second model that has not been inspected for wiring diagram data, and the process returns to step S13, and the processes of steps S13 to S16 are performed on the second model.

  In the second step S14, the secondary wiring information shown in the right diagram of FIG. 6B is created using the harness combination information of the second model included in the harness list information, and in the next step S15, the second model is created. All the wiring specification information is acquired. Subsequently, in step S16, as shown in FIG. 6B, based on the comparison between the information indicating the conduction path included in each wiring specification information and the information indicating the conduction path included in the secondary wiring information, The connection error of the wire harness included in the secondary wiring information is inspected. Then, in step S17, it is determined that there is no model information for which wiring diagram data is not inspected, and the flow shown in FIG. 4 ends.
