JP5890086B2 - Communication facility, communication cable laying method, and laying information management system - Google Patents

Description

  The present invention relates to a communication facility, a communication cable laying method, and a laying information management system that are useful in a communication cable such as an optical fiber, a laying operation of the communication cable, and a laying cable maintenance management.

  In a communication network such as an optical fiber, information (manufacturer, year of manufacture, model, length mark, etc.) of cables such as an optical cable to be installed is printed on the outer cover of the cable at regular intervals. Information on these cables is necessary for maintenance management after laying, but there is a possibility that printing may be lost due to deterioration over time or external factors. For this reason, conventionally, product information such as manufacturer, year of manufacture, and model has been manually transferred and managed by calculating the cable length based on the length mark.

  On the other hand, as an invention for providing cable laying work information using information recorded in a cable in advance, Patent Document 1 downloads work information associated with a cable ID and RFID attached to the cable. An invention is described in which a cable ID is read from a (Radio Frequency Identification) tag and work information is displayed on a portable information terminal.

Explain the problems of branch and trunk installation work.
FIG. 1 shows a cable layout, and FIG. 2 shows the structure of the round cable 10.
In the trunk laying operation, the trunk cable 1a is wired to the closure 3a. In the branch laying operation, the branch line cable 1b is wired to the closure 3b. In actual work, the worker 9 connects the core wires 12 one by one to the terminal of the closure 3 on the work table of the aerial work vehicle 8. The cord 12 at the center of the cable 10 has an identification code printed on the film, and the identification code is generated by combining the line color and line type, such as a blue line and a blue dotted line. In the field, this code is visually confirmed to perform wiring work. In this work, since the color and line type of the line printed on the thin line film are checked with the naked eye, there is a problem that the work cannot be performed when the visual acuity decreases. That's important because the veteran workers who work hard have to get out of the first line with only a little presbyopia.
Since this work is basically performed outdoors, when a wind blows or a large vehicle passes, both the cable and the work table vibrate, and it is difficult to visually confirm the identification code. Furthermore, during work on the pillars in the severe winter season, in the strong winds of snow mixing, the core film is peeled off with fingertips that are exposed to strong winds on the buckets of high-altitude work vehicles and the identification code is checked. As many as ten fibers must be connected. In such work, not only skill but also strong mental power and physical strength must be complete, and work is extremely difficult. Nevertheless, I can only say very much because I lose my job with a little presbyopia.
That is, in the operation of connecting the core 12 to the terminal of the closure 3, since the core 12 is identified by visual inspection of the identification code, there is a problem that it is easily affected by the physical condition of the operator 9 and the work conditions at the site. .

A problem in laying the lead-in wire 2 to the subscriber's house 5 will be described. FIG. 3 shows the structure of the lead-in wire 2.
In the operation of wiring the core wire 22 of the lead-in wire 2 to the closure 3b, the worker 9 gets on the work table of the work vehicle 8 and performs the wiring work at a height of about 5 meters or more above the ground. Generally, an identification code is not printed on the core wire 22 of the lead-in wire 2. Depending on the contractor, the core wire 22 may be identified by being labeled, but this label cannot be generally used because it differs depending on the time of enforcement or the contractor. Although it depends on the material of the label, deterioration of the label over time is also a problem. In addition, when it is cut off in the middle of the service line during a disaster such as a typhoon, the connection destination cannot be determined unless the start point is traced.
In other words, in the work of wiring the lead-in wire 2 to the subscriber's home 5, since an identification code is not attached to the lead-in wire, a label must be given, but it is difficult to give a unified identification code, Has a problem that a label cannot be given.

The problem when removing the lead-in line is explained.
Since the length of the lead-in wire wired from the closure 3b to the subscriber's house 5 passes through three or four utility poles, the total extension is about 150 meters. Also, since there are a maximum of 16 lead wires from the closure, several lead wires pass through the spiral wire, and the operator selects one of the target wires and removes it. There must be.
Generally, there is no correspondence between the service line 2 connected to the closure 3b and the subscriber's house 5. Accordingly, when removing the lead-in line, it is not possible to remove the lead-in line from the terminal of the closure 3b. Therefore, it is necessary to remove the lead-in line while following the lead-in line from the subscriber house 5 side. To follow the lead-in line, the aerial work vehicle is moved along the electric wire and removed from several lead-in lines while sequentially tracing one target. Therefore, the removal work is a serious work.
By the way, if the lead-in wire can be removed from the terminal of the closure 3b, it can be removed by pulling the wire from the subscriber's home 5 side, so that the removal work is very simple.
That is, in the operation of removing the lead-in wire 2, there is a problem in that the lead-in wire cannot be removed from the terminal of the closure 3b because the lead-in wire is not provided with an identification code. Therefore, in the removal work of the lead-in line, it must be removed while following from the subscriber's house 5 using an aerial work vehicle.

A problem that occurs when a part of the service line is broken during a typhoon disaster will be described.
When a cable breaks between the closure 3b and the customer's house due to a typhoon disaster, it is often difficult to examine the broken part. Normally, the service line was exchanged while following the cable from the customer's house using a bucket car.

  If the cable breaks due to an accident such as a fire along the line, replace all the lead-ins at the location where the accident occurred. Also in this work, since the service line 2 connected to the closure 3b does not correspond to the customer's house, the service line was removed from the customer's house side using a bucket car while removing the service line. .

Explain the problems when dealing with the relocation of telephone poles.
In the relocation of the utility pole, there is no correspondence between the service line 2 connected to the closure 3b and the customer's house, so the service line is removed from the customer's house by using a bucket car to remove the service line. It was.

  In addition, when responding to a disaster such as a typhoon disaster or an accident, or in response to a problem of relocation of a utility pole, it is necessary to identify the affected cable from the associated utility pole, but the information is organized manually.

From the above, a method that can identify optical cables, core wires, utility poles, and closures without visual observation and unified management of the obtained information are problems.
In other words, the development of methods and devices for electronically identifying cables and managing information in a database is a challenge.

  On the other hand, although the invention described in Patent Document 1 uses information recorded in the cable in advance, it only provides information for laying work and is used for maintenance management after laying. I can't.

  The present invention solves the above-described problems, and provides a laying information management system capable of easily creating and managing laying information necessary for maintenance management after cable laying in a communication network such as an optical fiber. Is.

The laying information management system according to claim 1 is a communication facility used for high-speed communication using an optical fiber, and includes a communication cable having a plurality of electronically identifiable tags and an electronically identifiable tag.

As an example of an electronically identifiable tag, an RFID tag can be used. An electronically identifiable RFID tag is attached to a communication facility from the station S to the subscriber's house 5, and the facility It was possible to identify where it was connected.
An RFID tag 11 is attached to the round cable 10 used for the trunk line 1a in addition to the conventional length mark.
In addition to the conventional length mark, the RFID tag 11 is attached to the round cable 10 used for the branch line 1b.
When the round cable 10 is installed on the utility pole 4, the RFID tag 41 is attached to the conventional common bill 44.
An RFID tag 21 is attached to the drop cable 20 used for the lead-in wire 2.
The RFID tag 31 is attached to the closure 3a that branches the main line into the branch line, and the RFID tag 14 is attached to the terminal of the closure.
The RFID tag 31 is attached to the closure 3b that branches the branch line into the lead-in line, the RFID tag 14 is attached to the upstream terminal of the closure, and the RFID tag 24 is attached to the downstream terminal.
An RFID tag 52 is attached to the home fiber terminator 51 installed in the subscriber home 5.
As a result, the branch from the main line to the branch line can be traced.

The invention according to claim 2 is characterized in that, in the laying information management system according to claim 1 , the terminal of the closure is specified based on the information of the tag of the lead-in line included in the laying information.

The invention according to claim 3 is characterized in that, in the laying information management system according to claim 1 , the terminal of the closure is specified based on the tag information of the terminal device included in the laying information.

  According to the present invention, when laying a cable, when identifying the cable and the core wire, connect the core wire of the round cable to the closure terminal, attach the RFID tag, and identify the connection destination and the subscriber by an electronic method. Can be registered in the database. Once registered in the database, thereafter, by reading the tag information electronically and searching the database, the core wire or closure of the round cable can be identified electronically. According to this method, since it is not necessary to visually confirm the identification code as in the prior art, the work can be performed without depending on visual acuity. Therefore, a skilled worker who has become presbyopic can engage in work without taking the handicap of visual acuity.

  Furthermore, when connecting to a database online using a communication line, it is possible to check the connection destination and subscriber on site. Thereby, it is possible to prevent work mistakes and improve work safety.

  According to the present invention, when the cable is removed, it is possible to electronically check which lead-in wire is connected to the subscriber's home at the terminal position of the closure. Therefore, the lead-in wire can be removed from the terminal block of the closure, and the lead-in wire can be pulled and removed from the subscriber's home side.

  According to the present invention, when dealing with the troubled transfer of the utility pole, the closure and the subscriber's house can be identified at the cut point.

  According to the present invention, when a failure such as a typhoon disaster or an accident occurs, it is possible to identify the closure and the subscriber's house at the location where the failure such as cable disconnection has occurred.

  As described above, according to the present invention, in a communication network such as an optical fiber and its laying work and maintenance work, it is impossible in the past by creating and managing laying information necessary for maintenance management at the time of cable laying work and after cable laying. This makes it possible to identify communication cables and core wires that are not visually observed, to confirm work contrasts, and to predict the impact range during a disaster.

The portable information terminal 60 stores the cable information in the storage unit.

g. Writing of laying information The worker 9 writes “construction information” as laying information that can be acquired at the work place on each RFID tag 11 affixed to the cable 10 of the trunk line 1 a by the writing unit of the RFID reading / writing device 70. Date "," GPS data ", etc. can also be written. (S1150).

h. Calculation of Cable Length The control unit of the RFID reader / writer 70 calculates the cable length of the installed trunk cable based on the distance information included in the cable information recorded in advance on each RFID tag 11 of the cable 10. (S1160). The RFID reading / writing device 70 sends the calculated cable length to the portable information terminal 60. The portable information terminal 60 stores the cable information in the storage unit.

i. Estimated cable length The operator 9 lays the cable 10 of the trunk line 1a. When the cable 10 reaches the planned length, the function key is pressed (S1170) or the like, and the cable 10 reaches the planned length in the system. It is memorized (S1180). In this case, in addition to the function keys, a mouse, key input or voice authentication may be used.

j. Reaching the utility pole The worker 9 lays the cable 10 of the trunk line 1a. When the worker 9 reaches the utility pole 4 (4a, 4b, 4c) in the middle, the function key is pressed to the utility pole 4 to the system. Notification of arrival is made (S1190). In this case, in addition to the function keys, a mouse, key input or voice authentication may be used.

k. Utility Pole Information The operator 9 reads the utility pole information of the RFID tag 45 with the utility pole number 43 pasted on the utility pole 4 (4a, 4b, 4c) by the reading unit of the portable information terminal 60, and stores it in the portable information terminal 60. (S1200). Further, even if the power pole information of the RFID tag 45 cannot be read due to some reason such as breakage of the power pole 4, the information on the RFID tag 41 attached to the collocated tag 44 attached to the cable near the power pole is read.

Planning for recovery work that can be accommodated with minimal impact.

e. Restoration work The worker 9 goes to the cable exchange work based on the restoration work plan.
Subsequent cable replacement work is performed in the same procedure as cable laying work.

  Since the laying information management system according to the present embodiment is configured as described above, the following operational effects can be obtained.

  When laying cables, when identifying cables and core wires, connect the core wire of the round cable to the closure terminal, attach an RFID tag, identify the connection destination and subscriber by electronic methods, and register them in the database. Will be able to. Once registered in the database, thereafter, by reading the tag information electronically and searching the database, the core wire or closure of the round cable can be identified electronically. According to this method, since it is not necessary to visually confirm the identification code as in the prior art, the work can be performed without depending on visual acuity. Therefore, a skilled worker who has become presbyopic can engage in work without taking the handicap of visual acuity.

  Furthermore, when connecting to a database online using a communication line, it is possible to check the connection destination and subscriber on site. Thereby, it is possible to prevent work mistakes and improve work safety.

  When the cable is removed, it is possible to electronically check which lead-in wire is connected to the subscriber's house at the terminal position of the closure. Therefore, the lead-in wire can be removed from the terminal block of the closure, and the lead-in wire can be pulled and removed from the subscriber's home side.

  When dealing with the problem of relocation of telephone poles, it is possible to identify the closure and the subscriber's house at the cutting point.

  When a failure such as a typhoon disaster or accident occurs, it is possible to identify the closure and the subscriber's house at the location where the failure occurred such as cable disconnection.

  A plurality of pieces of cable information are recorded along the length direction of the round cable 10 and the drop cable 20 to be laid, and the round cable 10 and the drop cable 20 are dropped by the RFID reading / writing device 70 as a cable information reading unit. Since the cable 20 is read as the cable is laid, the cable information need not be manually transferred separately, and can be easily collected. And since the read cable information is preserve | saved at the portable information terminal 60 and the laying information of the round cable 10 and the drop cable 20 to be laid is created, the laying information necessary for maintenance management after laying can be easily created. Can do.

  Further, the cable information includes distance information from the starting point of the installed round cable 10 and drop cable 20, and based on the distance information, the cable length is calculated by the RFID reading / writing device 70 serving as cable length calculation means. Since it is calculated, there is no need to calculate the cable length manually.

In addition, by including product information of the round cable 10 and the drop cable 20 installed in the cable information, it is possible to identify and extract the corresponding cable according to the specific manufacturing conditions such as the manufacturer and the manufacturing year, It can respond smoothly during maintenance management.
For example, when it is found that there is a lot defect in a cable, a cable to be replaced can be easily extracted and an affected customer can be identified by searching using the manufacturing number as a key. In addition, when the cable is replaced every elapsed year, the year of manufacture may be used as a key.

  In addition, since the portable information terminal 60 as the closure information reading means reads the closure information that identifies the closure to which the round cable 10 and the drop cable 20 to be laid are connected, and creates the laying information based on the read closure information. When performing maintenance management in units of closures, it is possible to identify the affected closures and identify the affected cables.

  Moreover, since the portable information terminal 60 which is a closure determination means determines whether the closure to be connected is a predesignated closure, it can be confirmed whether the closure 3b to be connected is correct.

  In addition, the portable information terminal 60 which is a utility pole information reading means reads the utility pole information for identifying the utility pole 4 through which the round cable 10 and the drop cable 20 to be installed pass, and creates the installation information based on the read utility pole information. When a failure such as a typhoon disaster or an accident occurs or when the trouble of a utility pole is transferred, an affected cable can be easily identified by selecting the relevant utility pole as a search key.

  As described above, according to the present embodiment, in the communication network and its laying work and maintenance work, it is impossible in the past by creating and managing laying information necessary for maintenance management at the time of cable laying work and after cable laying. This makes it possible to identify communication cables and cores that are not visually observed, to confirm work contrast objects, and to predict the range of impact during a disaster.

  In the present embodiment, an RFID tag is used to record each information, but there is no particular limitation as long as it can be read by a device.
