  In the present invention, cables such as metallic cables and optical fiber cables are installed between telephone poles on the ground or between power poles and buildings, or buried between manholes on the ground or between manholes and buildings. The present invention relates to a design support system for cable wiring used for improving convenience when wiring these cables indoors.

  When installing cables such as metallic cables and optical fiber cables as outdoor telephone lines and power lines, the utility poles installed by each power company or telephone company are used with each other. Cables will be installed after obtaining permission to use the utility pole. This procedure is carried out by creating and submitting a collocation application (common erection application) to the utility pole owner, and it is also necessary to follow the same procedure as a collocation change application when changing permitted facilities There is.

  For this reason, the management of cable wiring is to use a management system in the database owned by the power company or telephone company. For example, a wiring company requested a new optical fiber construction work from the telephone company. In this case, after confirming the optical fiber cable construction request form, which is the content of the order, from the database management system owned by the telephone company, confirm the new wiring route, check the construction site, and install the utility poles , Creation of handwritten design drawings and copying, handwritten core wire connection diagram creation is also required, and further, a series of design document work has been completed by performing process calculation and article calculation based on the design drawing Is made.

For this reason, a great deal of time and manpower is required from the construction request to the completion of the design work, and the relevance between the works despite the fact that the actual construction of the optical fiber cable is a continuous series of work. Because of its thinness, it was a lack of rationality with a lot of waste. Furthermore, since most of these design work is performed in a wiring company that is separate from the installation site, there are many differences between the created design document and the actual installation site, requiring revisions. Not a few, and the overall management is not perfect.

For such outdoor cable laying design and construction, Patent Document 1 is known regarding a line system such as an indoor cable wiring pipe. This technology is used for the management of new installation, relocation, and removal of indoor terminal computers. The equipment management data table and the construction management data table that store the current situation are stored in the storage device. A wiring route for connecting a plurality of terminals is determined with reference to the data.
Patent Document 2 is known as an optical fiber cable layout design planning support system. The present invention uses equipment map files represented by symbols on a map, displays each equipment related to an optical fiber cable network on a map, and uses the information on each equipment to transmit light between bases instructed. It searches for fiber cable laying routes, displays a list of candidate optical fiber cable routes, and selects the optimum fiber optic cable laying route.
