Further, the facility information DB 18 stores, for example, information indicating physical characteristics regarding the cable such as a theoretical value and an actual measurement value of the transmission loss, and various information regarding a user who is a user of the installed cable.

Communication line design / management system 1 shown in FIG.
0 can be used for designing the communication line of the communication cable and managing the communication line. In this communication line design / management system 10, a position on a map displayed on a display device is designated, and a desired facility, for example, a manhole on a road is defined at the position, or a station or a station is built in a building. User buildings can be defined. Furthermore, the communication line can be automatically designed by connecting these with a designated route. The user building means a building of a user who uses the communication line cable, and includes an office building, an apartment house, and a private house. Further, the cable here is not limited to the optical cable, and includes a metal cable. In addition, the cable represents a bundle of cores. The communication line data designed here can also be used for facility management. Facility management includes allocating empty cores and maintaining cables.

Next, the processing executed by the communication line design / management system 10 according to this embodiment will be described with reference to the system flowchart of FIG. This shows the processing executed when designing the communication line.

When the operator operates the input device to activate the communication line design / management system 10, a drawing menu 300 as shown in FIG. 3 is displayed on the screen of the display device. In the drawing menu, by designating an area and clicking the information acquisition button, the design processing unit 26 obtains the map data of the designated area from the map information DB, and the facility management related information DB 14
From the above, information on the facilities already arranged in the designated area is acquired, and the map generated from these is displayed on the screen of the display device (see the map image 301 in FIG. 3). In the present embodiment, various symbols and the like are superimposed on the map displayed on the screen of the display device. In addition,
Since the map displayed at this stage is under design, it is called a design map.

First, the operator operates the input device to input information (product number) for identifying the cable and physical characteristics (cable length, attenuation rate, etc.) (step 201).
In step 201, the window 400 shown in FIG. 4 opens in response to a predetermined operation by the operator. In this embodiment, a cable number, a cable classification, and a cable name can be defined. Facility information DB18
In addition, if the cable name and the physical characteristics of the cable to which the cable name is given are stored in advance in association with each other,
By defining the cable name, its physical characteristics can be specified. The information set in this step is stored in the design information DB 16.

Next, the operator operates a mouse or the like to specify a position on the design map, and pops up a facility information window. FIG. 5 is a diagram showing an example of the facility information window. As shown in FIG. 5, in the equipment information window 500, information regarding various items regarding each equipment is input. The items include a facility number that identifies the facility, a facility category indicating a handhole, a manhole, a station, etc., a facility name, a location, a target object, and the like.

An operator may directly input information to the facility information window 500, or information on various facilities (for example, refer to tabular data in FIG. 6) is prepared in advance in the facility information DB 18. Then, it is possible to open the window 600, select a predetermined facility, and import the value in the facility information DB into the facility information window 500. In this way, input of equipment information
Registration is completed (step 202).

Next, the operator operates the input device to
Various facilities set in the facility information window 500 are arranged on the design map (step 203). Here, it is realized by selecting a desired position on the displayed map and designating the equipment to be arranged. By the arrangement of the equipment, the equipment set in step 202 is associated with the position (coordinates) to be arranged. The design information DB also includes information indicating the association between the set equipment and the coordinates.
16 are stored.

When step 203 is completed, symbols indicating the manholes, stations, and user buildings placed by the user are displayed on the design map. Alternatively, in the process of step 203, the symbols may be displayed on the design map according to the arrangement of the user.

Next, input / registration of inter-equipment information including processing for determining a route for extending the line from the station is executed (step 204). Here, it is possible to specify a connection type such as a loop type or a star type, a connection between manholes, and a branch of a line. For example, the user can operate the input device to pop up an input window as shown in FIG. 7, and specify a station and a manhole, a manhole and a manhole, etc. to be connected here. Although the example of FIG. 7 shows the main line, it is possible to set a branch including another loop in another input window.

In the present embodiment, characters and the like are entered in the items in the window shown in FIG. 7, but the present invention is not limited to this. For example, by sequentially selecting the facilities arranged on the map in step 203, the characters may be automatically input to the items in the window. For example, by designating a station on the map, "station" is automatically entered as the upper equipment name in the field indicating the first section connection (see reference numeral 701), and then the station By specifying the manhole to be connected, the specified manhole name may be automatically input as the lower equipment name (reference numeral 7).
02).

In accordance with the inter-equipment information set in step 204, the symbols on the design map are connected by lines representing cables (step 205). Thus, for example, as shown in FIG. 8, on the design map,
For example, a loop-type communication line (see reference numeral 801 in the figure) that reaches the user building through the designated manhole from the station and returns to the station via a predetermined route is displayed.

On the other hand, on the basis of the equipment information and the equipment-to-equipment information, a cable connection schematic diagram is created in which only the equipment and the cables connecting these are taken out (step 20).
6). FIG. 9 shows an example of a schematic diagram of cable connection.
As shown in FIG. 9, in the cable connection schematic diagram 900, it is shown which manhole the cable extends through and which user building. In the example of FIG. 9, station 9
It can be understood that a loop is formed from 01 and the line reaches six users (for example, reference numeral 902).

By the above processing, the routes of the facilities and cables arranged on the map are determined. Therefore, when the operator gives an instruction to update the equipment management related information, the information created in steps 201 to 206 is stored in the equipment management related information DB 14 (step 207). After that, when the facility management related information DB 14 is accessed and a management map (management map) is opened, a map including various information designed in steps 201 to 206 is displayed.

Next, the operator sets information (cord information) regarding each core wire forming the cable. Here, the operator operates the input device to open the window 1000 as shown in FIG. 10, and defines the correspondence between the cable core number and the core number on the user building side at the connection point to the user building. (Step 208). Based on this definition, a detailed connection point diagram as shown in FIG. 11 can be obtained. In the example shown in FIGS. 10 and 11, the main wire side, that is, the core wire numbers 21 to 40 of the cable forming the loop correspond to the core wire numbers 1 to 20 of the user side, respectively. It is shown that

When the connection of the core wires at the connection points is defined, the core wire connection diagram is created according to the operation of the operator. FIG. 12 shows an example of a core wire connection diagram. As shown in FIG. 12, in the cable connection schematic diagram, the connection points are shown in detail in the cable connection schematic diagram, as in FIG. 11. FIG. 13 is an enlarged view of a core connection diagram at a certain connection point. After the core line information is fixed, the line pair list is updated based on this information. This line pair list is stored in the facility management related information DB 14 (step 209).

As described above, in the present embodiment, various facilities can be defined on the map in the map DB 20 to design the communication line. Therefore, it becomes possible to proceed with the design while referring to the map and the facilities already arranged. Further, as the design is completed, the design information is stored in the facility management-related information DB 14 as management data, which can be useful for subsequent maintenance and management. Further, the facility information DB stores physical characteristics including theoretical values and measured values of transmission loss required for maintenance, and the management processing unit 28 stores the facility management related information DB1.
Since various cables in 4 can be specified and the physical characteristics of the cables can be referred to, smoother maintenance management can be realized.

The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. It goes without saying that this is what is done. For example, although a manhole or a station is newly installed on the map in the above-mentioned embodiment, data of another communication conduit (for example, underground buried cable) is stored in the map DB 20, By displaying a map in which the other communication conduits are superimposed, it becomes possible to design a communication line using the existing conduits.

Further, it is possible to realize smoother maintenance management by cooperating with the customer management DB and the DB of the communication pipeline design system (civil engineering equipment) relating to the civil engineering equipment. In the above embodiment, the communication line design / management system 10 is provided with the facility management related information database 14, the design information database 16, the facility information database 18, and the map database 20, and these databases are accessed. It is not limited to such a form. For example, the database is
Each is connected to another computer (server), and the communication line design / management system 10 accesses the server via a network such as the Internet to acquire data from the database or write data in the database. It may be configured. Any database may be connected to the other computer via the network. Furthermore, in the above embodiment, both design and management are executed in the communication line design / management system 10, but these processes may be executed by separate computers. .
