Abstract

A method for determining a wiring risk is a method for determining a first risk that electric wires connected to a plurality of terminal devices are bundled into a single harness, and a second risk that harnesses fail at the same time, wherein the first risk is determined by identifying the number of connectors to which a target harness identified from the plurality of harnesses is indirectly connected, and the second risk is determined by matching location information of the target harness to an influenced area by a hazard source, and identifying whether the target harness passes through the influenced area.

Claims

1. A method for determining a wiring risk which is a method for determining a first risk that electric wires connected to a plurality of terminal devices are bundled into a single harness, and a second risk that harnesses fail at the same time

in a wiring system in which the plurality of harnesses each as a bundle of electric wires are provided between the plurality of terminal devices and connected via connectors, wherein

the first risk is determined by

identifying the number of connectors to which a target harness identified from the plurality of harnesses is indirectly connected, and

the second risk is determined by

matching location information of the target harness to an influenced area by a hazard source, and

identifying whether the target harness passes through the influenced area.

2. The method for determining a wiring risk according to claim 1,

wherein in the determination of the first risk,

identification information of an electric wire bundled in the target harness, the electric wire having a risk value corresponding to the identified number of connectors equal to or larger than a predetermined value, is extracted from a connection information between the connector and the harness.

3. The method for determining a wiring risk according to claim 1,

wherein in the determination of the first risk,

identification information of a node as a branching portion of the target harness, the node having a risk value corresponding to the identified number of connectors equal to or larger than a predetermined value, is extracted.

4. The method for determining a wiring risk according to claim 1,

wherein in the determination of the second risk,

the second risk of two target harnesses is obtained by calculating respective risk values indicating that the two target harnesses pass through the influenced area.

5. The method for determining a wiring risk according to claim 2,

wherein in the determination of the second risk,

the second risk of two target harnesses is obtained by calculating respective risk values indicating that the two target harnesses pass through the influenced area.

6. The method for determining a wiring risk according to claim 3,

wherein in the determination of the second risk,

the second risk of two target harnesses is obtained by calculating respective risk values indicating that the two target harnesses pass through the influenced area.

7. A wiring risk determination system which determines a first risk that electric wires connected to a plurality of terminal devices are bundled into a single harness, and a second risk that harnesses fail at the same time

in a wiring system in which the plurality of harnesses each as a bundle of electric wires are provided between the plurality of terminal devices and connected via connectors, wherein

the system includes

a database that stores connection information between the connector and the harness, and location information of the harnesses and information on an influenced area by a hazard source, and

a processing unit that determines the first risk and the second risk, and

when a target harness identified from the plurality of harnesses is specified,

the processing unit identifies the number of connectors to which the target harness is indirectly connected based on the connection information so as to determine the first risk, and

matches the location information of the target harness to the influenced area information, and

identifies whether the target harness passes through the influenced area so as to determine the second risk.

8. The wiring risk determination system according to claim 7,

wherein in the determination of the first risk,

the processing unit extracts identification information of an electric wire bundled in the target harness, the electric wire having a risk value corresponding to the identified number of connectors equal to or larger than a predetermined value, from the connection information.

9. The wiring risk determination system according to claim 7,

wherein in the determination of the first risk, the processing unit extracts identification information of a node as a branching portion of the target harness, the node having a risk value corresponding to the identified number of connectors equal to or larger than a predetermined value, from the connection information.

10. The wiring risk determination system according to any one of claim 7,

wherein in the determination of the second risk,

the processing unit obtains the second risk of two target harnesses by calculating respective risk values indicating that the two target harnesses pass through the influenced area.

11. The wiring risk determination system according to any one of claim 8,

wherein in the determination of the second risk,

the processing unit obtains the second risk of two target harnesses by calculating respective risk values indicating that the two target harnesses pass through the influenced area.

12. The wiring risk determination system according to any one of claim 9,

wherein in the determination of the second risk,

the processing unit obtains the second risk of two target harnesses by calculating respective risk values indicating that the two target harnesses pass through the influenced area.
