Description

この発明は、電柱から各家屋へ配されている引込線の撤去作業に関する。   The present invention relates to a removal operation of a lead-in wire arranged from a utility pole to each house.

生活環境や住宅事情の変化に伴い、全国的に空き家が増加している。人が住まなくなった空き家は、従来は次の入居者が利用することを想定して電話線などのインフラを残すことが一般的であった。しかし、恒常的に人が住まなくなる空き家の増加が無視できなくなると、それらのインフラの撤去が必要となってくる。   Vacant homes are increasing nationwide with changes in living conditions and housing conditions. It has been common for vacant houses that no longer have people to live to leave infrastructure such as telephone lines, assuming that the next tenant will use them. However, if the increase in vacant homes where people do not live regularly cannot be ignored, it will be necessary to remove those infrastructures.

また、光ファイバー網の発達に伴い、電話線が担ってきた役割を光ファイバーによるIP電話が担う家屋も増加している。このため、空き家でなくても従来のメタル線は不要で撤去したいという需要も増えてきている。   In addition, with the development of optical fiber networks, the number of houses that IP telephones using optical fibers play the role that telephone lines have played has increased. For this reason, even if it is not a vacant house, the demand for removing the conventional metal wire is unnecessary and increasing.

電柱から各家屋へ配されている引込線は道路を跨いでいることも多く、そのまま残しておくと垂れ下がって事故の原因になる可能性が無視できない(非特許文献1)。そこで、引込線が不要になった家屋に通じている線を順次撤去することになる。   The service lines from the utility pole to each house often straddle the road, and if left untouched, the possibility of drooping and causing an accident cannot be ignored (Non-Patent Document 1). Therefore, the line leading to the house where the service line is no longer necessary will be removed sequentially.

この撤去作業は現場で引込線を物理的に除去するだけでは終わらない。その引込線に通じてサービスを提供するインフラ業者は、各々の引込線へ通じる端子盤を有しており、その端子盤での作業も必要になる。しかし、設置から長い年数が経っていることもあり、古い時代に設定された配線ほど、端子盤のどの配線がどの家屋の引込線に対応しているかが、確実な情報として記録されていない場合がある。   This removal operation does not end simply by physically removing the lead-in wire at the site. An infrastructure company that provides services through the service lines has a terminal board that leads to each service line, and requires work on the service board. However, since many years have passed since installation, the wiring that was set in the old era may not be recorded as reliable information as to which wiring on the terminal board corresponds to which service line. is there.

“NTT設備に関する不安全状況のご投稿”、[online]、NTT西日本、[平成30年10月25日検索]、インターネット<URL:https://www.setsubi-info.ntt-w.net/webFuanzen/select/applySelect/show>“Contribution of unsafe situation regarding NTT equipment”, [online], NTT West, [October 25, 2018 search], Internet <URL: https://www.setsubi-info.ntt-w.net/ webFuanzen / select / applySelect / show>

現状では、端子盤にて本来封鎖すべき配線であるか否かを判別するには、端子盤の前で少なくとも一名の所内専属担当が待機した状態で、各家屋に派遣された作業員が所内専属担当に携帯電話で通話しながら、撤去しようとする引込線の両端をショートさせる。所内専属担当は、電流が流れることでわかるランプの点灯やブザーの発音を確認し、電流が流れたか否かを作業員に口頭で伝える。これにより、間違いなく撤去しようとする家屋の引込線に対応する配線であることを確かめた上で、端子盤の該当部分から撤去、又は変更等を行う。   At present, in order to determine whether or not the wiring is to be sealed on the terminal board, at least one in-house staff member is waiting in front of the terminal board, and a worker dispatched to each house While talking to the person in charge at the institution using a mobile phone, short-circuit both ends of the service line to be removed. The person in charge at the institution confirms the lighting of the lamp and the sound of the buzzer that can be understood by the current flowing, and verbally tells the worker whether the current has flowed. As a result, after confirming that the wiring corresponds to the lead-in wire of the house to be removed without fail, the terminal board is removed or changed.

しかしこの作業にあたっては、前記所内専属担当が常時待機していなければいけない。各家屋に派遣される作業員が各家屋へ移動する時間と配線を取り出すための作業時間とに亘って待たねばならないため、この待ち時間は多大なものになり、効率が悪かった。   However, in this work, the in-house dedicated staff must always be on standby. Since the worker dispatched to each house has to wait for the time to move to each house and the work time for taking out the wiring, this waiting time becomes enormous and inefficient.

そこでこの発明は、所内専属担当が端子盤前で確認作業のために待機しなくても、現場で作業する作業員のみで引込線の確認ができるようにすることを目的とする。   SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to make it possible to confirm a lead-in wire only by a worker working at the site, even if the in-house dedicated staff does not wait for confirmation work in front of the terminal board.

As a procedure,
Of the terminal board connected to the lead-in wire drawn into a plurality of houses, connecting the terminal board terminal assumed to be connected to the lead-in line scheduled to be confirmed, and the terminal of the core wire contrast device of the present invention,
And the mobile phone is fixed to the mobile phone fixing portion in a state where the mobile phone can be automatically received.
Preparation steps,
While making a call to the mobile phone, short-circuit the end of the lead-in line to be confirmed, and confirming the sound of the speaker through the mobile phone,
Execute.

ここで、上記携帯電話機は自動着信できる端末であることが必要となる。すなわち、着信があった際には、スイッチやパネルの操作をすることなく通話モードに切り替えできるものである必要がある。実際にはフューチャーフォンでもスマートフォンでもよい。作業開始前に、自動着信するモードに切り替えた上で前記携帯電話機固定部に固定する。   Here, the mobile phone needs to be a terminal that can automatically receive a call. That is, when there is an incoming call, it is necessary to be able to switch to the call mode without operating a switch or panel. In fact, it can be a future phone or a smartphone. Before starting the work, the mode is switched to the automatic incoming call mode and fixed to the mobile phone fixing unit.

すなわち、撤去する予定の引込線の確認にあたっては、予めこの心線対照器を、多数の各家屋の引込線に繋がる端子盤の近傍に設置する。そして、その日に現場で確認する予定の家屋に繋がっていると想定される端子盤の端子から、心線対照器の両端の端子にそれぞれ接続する。このとき、複数の家屋に繋がる端子盤の端子について、それぞれ並列になるように心線対照器のそれぞれの端子に接続しておいてよい。ここまでが事前準備である。   That is, when confirming the lead-in line scheduled to be removed, this core wire contrast device is previously installed in the vicinity of the terminal board connected to the lead-in lines of many houses. And it connects to the terminal of the both ends of a core wire contrast device from the terminal of the terminal board assumed to be connected to the house which is scheduled to confirm on the spot on that day. At this time, the terminals of the terminal board connected to the plurality of houses may be connected to the terminals of the cord contrast device in parallel with each other. This is the preliminary preparation.

その上で、作業員は確認の現場となる家屋に到着し、撤去予定の引込線の両端を確認する。その上で、前記心線対照器に固定した携帯電話機に対して、電話網を用いて発呼を行う。発呼された前記携帯電話機は自動着信により、通話モードに切り替えられる。これにより、端子盤前の音声が各家屋にいる作業員に届くようになる。通話状態を続けたままで、作業員は引込線の両端をショートさせる。このとき、ショートさせた引込線が、予め心線対照器の端子に接続しておいた端子盤の端子に繋がっているのであれば、前記スピーカから音声が発せられ、その音声を拾った前記携帯電話機は通話中の作業員の電話にその音声を伝える。これにより、ショートさせた引込線が、予め端子盤で前記心線対照器に接続した端子の一つに繋がることが確認できる。   After that, the worker arrives at the house to be confirmed and confirms both ends of the service line to be removed. Then, a call is made using the telephone network to the mobile phone fixed to the cord contrast device. The called mobile phone is switched to a call mode by automatic incoming call. Thereby, the voice in front of the terminal board reaches the workers in each house. While continuing the call, the worker shorts both ends of the lead-in wire. At this time, if the lead-in wire that has been short-circuited is connected to a terminal of a terminal board that is connected in advance to the terminal of the core wire contrast device, a sound is emitted from the speaker, and the mobile phone that picks up the sound Transmits the voice to the worker's telephone during a call. Thereby, it can be confirmed that the shorted lead-in wire is connected to one of the terminals previously connected to the core wire contrast device on the terminal board.

この発明により、各家屋に導入された引込線を撤去するにあたり、当該引込線に接続されたインフラ業者の端子盤における端子がどれであるかを確認する際に、確認のための人員が端子盤を設置した社屋内で待機するまでもなく、作業員単独で確認を進めることができる。これにより、引込線の撤去や確認作業の現場に投入できる人員を増やすことができる。   According to this invention, when removing the lead-in wire introduced into each house, when confirming which terminal in the terminal board of the infrastructure contractor connected to the lead-in wire, personnel for confirmation install the terminal board Confirmation can be carried out by the worker alone without having to wait in the office. As a result, it is possible to increase the number of personnel that can be thrown into the field for the removal of the lead-in wire or the confirmation work.

以下、この発明について具体的な実施形態とともに詳細に説明する。この発明にかかる心線対照器11の配線図を含む概念図を図1に示す。まず、心線対照器11の基本構成について説明する。心線対照器11は、端子12a,12bと、電源13と、スピーカ14と、携帯電話機固定部15とを有する。   Hereinafter, the present invention will be described in detail together with specific embodiments. FIG. 1 is a conceptual diagram including a wiring diagram of the core wire contrast device 11 according to the present invention. First, the basic configuration of the core wire contrast device 11 will be described. The core wire contrast device 11 includes terminals 12 a and 12 b, a power source 13, a speaker 14, and a mobile phone fixing unit 15.

端子12a,12bは、配線において両極となる箇所に、それぞれ一つ以上設けられている。それぞれが並列になるように複数個設けられていてもよい。図1ではそれぞれ4端子設けられているが、端子12aのそれぞれ、端子12bのそれぞれは同じ電位となる。それぞれの端子には、端子盤31に繋がるケーブル32が接続される。   One or more of the terminals 12a and 12b are provided at locations that are opposite to each other in the wiring. A plurality of them may be provided in parallel. Although four terminals are provided in FIG. 1, each of the terminal 12a and each of the terminals 12b has the same potential. A cable 32 connected to the terminal board 31 is connected to each terminal.

電源13は搭載した電池でもよいし、交流の外部電源を変換したものでもよく、特に限定されない。スピーカ14を鳴らす程度の電流量が供給できるものであれば問題なく用いることができる。   The power source 13 may be a mounted battery or may be a converted AC external power source, and is not particularly limited. Any device that can supply an amount of current sufficient to sound the speaker 14 can be used without any problem.

スピーカ14は、電流が流れることで音声を発することができる装置である。通電を確認するためのものであるため、ブザー音を鳴らすことができるもので問題なく用いることができる。   The speaker 14 is a device that can emit sound when a current flows. Since it is for confirming energization, it can sound a buzzer and can be used without any problem.

携帯電話機固定部15は、携帯電話機16を固定することができる構成要素である。スピーカ14が発する音声を携帯電話機16のマイク部分で拾うことができる位置に設けてある必要がある。固定する方法は特に限定されるものではない。心線対照器11の筐体に溝や凹みを設けてそこに携帯電話機16を据えてもよいし、面ファスナーを貼り付けて携帯電話機16に貼り付けた対になる面ファスナーで貼り付けてもよいし、両面テープその他の粘着テープによって貼り付けてもよい。   The mobile phone fixing unit 15 is a component that can fix the mobile phone 16. It is necessary to be provided at a position where the sound emitted from the speaker 14 can be picked up by the microphone portion of the mobile phone 16. The fixing method is not particularly limited. A groove or a recess may be provided in the casing of the core wire contrast device 11 and the mobile phone 16 may be placed there, or a hook-and-loop fastener may be attached to a pair of hook-and-loop fasteners attached to the mobile phone 16. Alternatively, it may be affixed with a double-sided tape or other adhesive tape.

携帯電話機16は、心線対照器11に含まれないが、心線対照器11の携帯電話機固定部15に固定して用いる、自動着信できる端末であることが必要となる。自動着信とは、着信があった際に、スイッチやパネルの操作を人がすることなく通話モードに切り替えできるものである必要がある。実際にはフューチャーフォンでもスマートフォンでもよい。また、移動体通信網に直接接続するものである必要はなく、固定電話やIP電話の子機でもよい。端末固有の機能で自動着信できない場合には、別途ソフトウェアをインストールして自動着信する機能を付与できれば使用できる。   Although the mobile phone 16 is not included in the core wire contrast device 11, it is necessary to be a terminal that can be used automatically and used by being fixed to the mobile phone fixing portion 15 of the core wire contrast device 11. The automatic incoming call needs to be able to switch to the call mode without an operation of a switch or a panel when an incoming call is received. In fact, it can be a future phone or a smartphone. Further, it does not have to be directly connected to the mobile communication network, and may be a handset of a fixed telephone or an IP telephone. If automatic reception is not possible due to the function specific to the terminal, it can be used if a software can be installed and a function for automatic reception can be provided.

また、心線対照器11は、回路の安全性を確保するため、スピーカ14に対して並列に、抵抗17とダイオード18とを直列にして接続しておくと望ましい。その他、電源ランプ19(図2(b)参照)やスイッチなど、電源を有する一般的な機器が有する機能や部位を有していてよい。   Further, it is desirable that the core wire contrast device 11 has a resistor 17 and a diode 18 connected in series with the speaker 14 in parallel in order to ensure the safety of the circuit. In addition, the power supply lamp 19 (see FIG. 2B), a switch, and the like may have functions and parts of general equipment having a power supply.

このような心線対照器11の実施形態例を図2に示す。図2(a)が背面写真、図2(b)が平面写真、図2(c)が正面写真、図2(d)が左側面写真、図2(e)が右側面写真である。背面には端子12a、端子12bがそれぞれ上下に5つづつ配置されている。上部の5つの端子12aと下部の5つの端子12bはそれぞれ等価な電位である。筐体の上部平面にはブザー孔21が設けられており、その内部にスピーカ14が備え付けられている。また上部平面にはブザー孔21に隣接して、面ファスナーを両面テープで貼り付けた携帯電話機固定部15が設けてある。右側面には電源ジャック20が設けられてあり、AC−DC変換回路を経て電源13として供給される。   An embodiment of such a cord contrast device 11 is shown in FIG. 2A is a rear view, FIG. 2B is a plan view, FIG. 2C is a front view, FIG. 2D is a left side view, and FIG. 2E is a right side view. On the back surface, five terminals 12a and 12b are arranged one above the other. The upper five terminals 12a and the lower five terminals 12b have equivalent potentials. A buzzer hole 21 is provided in the upper plane of the housing, and a speaker 14 is provided therein. Further, on the upper plane, a mobile phone fixing portion 15 is provided adjacent to the buzzer hole 21 and a hook-and-loop fastener is attached with a double-sided tape. A power jack 20 is provided on the right side surface, and is supplied as a power source 13 through an AC-DC conversion circuit.

この発明にかかる心線対照器11を端子盤31と接続した状態の写真を図3に示す。基本的には端子盤31はインフラ業者の管理社屋内に設置されたものである場合が多い。端子盤31に並んだ端子盤端子33はそれぞれ対になっており、設置された社屋の外へ繋がり、電柱や地下トンネルに設けられた電線を通じて、終端は各家屋の引込線となって各家屋内に繋がっている。ここで、図3の端子盤は固定電話用の端子盤を例に示している。なお、便宜上家屋と呼ぶが、個別ではない団地内の各家庭に該当する一室や事業者の社屋、電話ボックスなども当然に含む。一家屋に2回線以上の引込線が導入されている場合もあり、その場合は個々の回線ごとに端子盤端子33に繋がっている。以下の説明では実際の作業に向かう目的地の都合上、家屋単位で説明する場合があるが、実際には回線単位で管理される。それぞれの端子盤端子33を、ケーブル32で端子12a,12bと接続する。なお、ケーブル32の両端はクリップなどが接続されていると、取り付け及び取り外しが容易で望ましい。   A photograph of a state in which the cord contrast device 11 according to the present invention is connected to the terminal board 31 is shown in FIG. Basically, the terminal board 31 is often installed in an infrastructure company management company. The terminal board terminals 33 arranged in the terminal board 31 are paired with each other, are connected to the outside of the installed company building, and are terminated at each house through the electric poles and electric wires provided in the underground tunnel. It is connected to. Here, the terminal board of FIG. 3 shows a terminal board for a fixed telephone as an example. In addition, although called a house for convenience, it naturally includes a room corresponding to each household in a housing complex that is not individual, a company's office, a telephone box, and the like. There may be a case where two or more service lines are introduced in one house, in which case each individual line is connected to the terminal board terminal 33. In the following explanation, there is a case where it is explained in units of houses for the convenience of the destination heading for the actual work, but in practice it is managed in units of lines. Each terminal board terminal 33 is connected to the terminals 12 a and 12 b by a cable 32. It should be noted that it is desirable that attachment and detachment be easy if both ends of the cable 32 are connected to clips or the like.

この発明にかかる心線対照器11を用いて、引込線撤去作業前の確認を作業員単独で行う確認方法の具体的手順例を、図4のフローチャートとともに説明する。まず(S101)、その日作業員が確認する回線とそれが繋がった家屋の住所とを予めリストアップする(S102)。この作業は前日までに行っておき、長期的な作業計画を立てておいてもよい。当日確認する引込線に繋がる回線のリストを参照して、その回線に繋がっている端子盤31の端子盤端子33の対を確認する(S103)。端子盤31はサービス提供会社の社屋にあるものに限定されず、多数の家屋へ導入される引込線に繋がっているものであれば実用できるが、ここでは電話会社が管理する端子盤31を例に説明する。この端子盤31には図3に示すように、多数の家屋の引込線25に通じている端子盤端子33の対が多数並べられている。この中から、リストに該当する家屋の引込線25に繋がる端子盤端子33の対を、心線対照器11の端子12a,12bとケーブル32で接続する(S104)。これを、当日行うリスト全件について行う(S105)。ただし、その日の作業途中で一旦社屋に戻る計画である場合には、その戻る前に行うべき回線の分だけ行っておけばよい。なお、心線対照器11の端子(12a,12b)数がリストの件数に比して大幅に少なくても、単純に並列で繋ぐという配線の原則に従うのであれば、多数のケーブル32を一つの端子(12a,12b)に接続してもよい。   A specific procedure example of a confirmation method in which the worker alone performs confirmation before the lead-in wire removal work using the core wire contrast device 11 according to the present invention will be described with reference to the flowchart of FIG. First (S101), the line that the worker confirms on the day and the address of the house to which it is connected are listed in advance (S102). This work may be done by the previous day and a long-term work plan may be made. The pair of terminal board terminals 33 of the terminal board 31 connected to the line is confirmed with reference to the list of lines connected to the service line to be checked on the day (S103). The terminal board 31 is not limited to the one in the service provider's office, but can be used as long as it is connected to the service line introduced into many houses. Here, the terminal board 31 managed by the telephone company is taken as an example. explain. As shown in FIG. 3, the terminal board 31 has a large number of pairs of terminal board terminals 33 communicating with the service lines 25 of many houses. From this, the pair of terminal board terminals 33 connected to the lead-in wire 25 of the house corresponding to the list is connected to the terminals 12a and 12b of the core wire contrast device 11 by the cable 32 (S104). This is performed for all items on the day (S105). However, if you plan to return to the office once during the day's work, you only need to go as many lines as you need before returning. Even if the number of terminals (12a, 12b) of the core wire contrast device 11 is significantly smaller than the number of items in the list, a number of cables 32 can be connected to a single cable as long as the wiring principle of simply connecting them in parallel is followed. You may connect to a terminal (12a, 12b).

また、端子盤端子33との接続作業と前後して、携帯電話機16を携帯電話機固定部15に固定する(S106)。固定した上で、自動着信モードに設定する(S107)。なお、この作業専用に自動着信モードにした携帯電話機16を予め固定し続けておいてもよい。従って、S106及びS107はS102〜S105と前後してもよい。ここまでが事前準備ステップである。   Further, before and after the connection work with the terminal board terminal 33, the mobile phone 16 is fixed to the mobile phone fixing portion 15 (S106). After fixing, the automatic incoming call mode is set (S107). Note that the mobile phone 16 in the automatic incoming call mode dedicated to this work may be fixed in advance. Therefore, S106 and S107 may be before and after S102 to S105. This is the preparatory step.

次に、実態確認ステップへ移る。作業員はリストアップされた家屋の現場へ移動する(S111)。家屋内で引込線25の端部を確認する(S112)。電話線の場合、電話台付近に露出していることが多いが、端部が発見できずに引込線25の途中しか見あたらない場合は、一旦屋外に出て、屋外の電柱26の近傍に設けられた接続端子函27内部のケーブル心線と引込線との接続部を、引込線25の端部として扱う。引込線25の端部を確認できたら、作業員は携帯電話機16へ発呼する(S113)。この際には別途持参した携帯電話機を用いるとよい。呼び出された携帯電話機16は、自動着信によって作業員が手にする携帯電話との間での通話モードに切り替わる(S114)。これにより、社屋の端子盤31前に設置された心線対照器11周辺の音声が、作業員の手元の携帯電話に伝達される。なお、手にしたままでは作業しづらいため、作業員の手元の携帯電話ではハンズフリーとなるイヤホンなどを併用すると望ましい。その通話モードを続けた状態で、作業員は引込線25の端部を短絡する(S115)。これで携帯電話機16から作業員の携帯電話を通じてブザー音が確認できれば(S116→Y)、その家屋の引込線25は、リストアップし社屋内で予め接続した端子の一つに繋がっていることが確認できたことになる(S117)。一方、ブザー音が確認出来ない場合(S116→N)、その引込線25は、少なくとも社屋内の予め接続した端子のどれにも繋がっていないというということになる(S118)。この場合、後日に端子盤31と引込線25との接続を記録したリストを見直し、確認する必要があることが確かめられたことになる。   Next, the process proceeds to the actual condition confirmation step. The worker moves to the listed site of the house (S111). The end of the lead-in wire 25 is confirmed inside the house (S112). In the case of a telephone line, it is often exposed in the vicinity of the telephone stand. However, when the end portion cannot be found and only the middle of the lead-in line 25 is found, the person goes outside and is provided in the vicinity of the electric pole 26 outdoors. The connection portion between the cable core wire and the lead-in wire inside the connection terminal box 27 is handled as the end portion of the lead-in wire 25. When the end of the lead-in wire 25 is confirmed, the worker calls the mobile phone 16 (S113). In this case, a mobile phone brought separately may be used. The called mobile phone 16 is switched to a call mode with the mobile phone held by the worker by automatic incoming call (S114). Thereby, the sound around the core wire contrast device 11 installed in front of the terminal board 31 of the company building is transmitted to the mobile phone at hand of the worker. In addition, since it is difficult to work with the hand held, it is desirable to use a hands-free earphone together with the mobile phone at hand of the worker. In the state where the call mode is continued, the worker short-circuits the end of the lead-in wire 25 (S115). If the buzzer sound can be confirmed from the cellular phone 16 through the worker's cellular phone (S116 → Y), it is confirmed that the lead-in wire 25 of the house is connected to one of the terminals that are listed and pre-connected inside the company. This is done (S117). On the other hand, when the buzzer sound cannot be confirmed (S116 → N), it means that the lead-in wire 25 is not connected to at least any of the pre-connected terminals in the office (S118). In this case, it is confirmed that it is necessary to review and confirm the list in which the connection between the terminal board 31 and the lead-in wire 25 is recorded at a later date.

以上で、その家屋における引込線25の確認を作業員は一人で完了することができ、一旦携帯電話による通話を終了して次の現場へ向かう(S119)。以降はS111からの流れを繰り返す。   Thus, the worker can complete the confirmation of the service line 25 in the house alone, and once the mobile phone call is finished, the worker goes to the next site (S119). Thereafter, the flow from S111 is repeated.
