Description

作業時刻記録装置、作業時刻記録システム、作業時刻記録方法および作業時刻記録プログラムWorking time recording device, working time recording system, working time recording method and working time recording program
　本発明は、保守作業を行った作業時刻を記録する作業時刻記録装置、作業時刻記録システム、作業時刻記録方法および作業時刻記録プログラムに関する。 The present invention relates to a work time recording device, a work time recording system, a work time recording method, and a work time recording program for recording work time of maintenance work.
　電話やインタネット等の物理的な通信回線では、旧型の通信設備から新型の通信設備への交換や故障設備の交換などの工事が日々行われている。このような工事の監督者は、作業に改善点が無いか等の観点で分析するために、工事の作業記録が必要である。それゆえ、現場作業者には、作業時刻等の記録を残しながら作業し、工事後に報告することが求められている。 For physical communication lines such as telephones and the Internet, construction work such as replacement of old communication equipment with new communication equipment and replacement of faulty equipment is carried out on a daily basis. A supervisor of such construction requires work records of the construction in order to analyze the work from the viewpoint of whether or not there is any point for improvement. Therefore, field workers are required to work while keeping records of work time and the like, and to report after the work is completed.
　通信設備の作業は、大きく２つに分けられる。一つは、操作端末を用いて通信設備をコマンドで操作するような作業であり、この作業は、作業時刻や作業内容を自動的に記録することができる。他の一つは、手作業や目視確認などであり、ＩＣＴ機器を介さずに行われるため、一般的に作業記録が残らないものである。後者の手作業の例としては、ケーブルやヒューズ、パッケージ等の挿抜や測定器の接続／取り外しの作業がある。目視確認の例としては、ランプや各種ロック状態などの確認作業がある。これらの作業は、現場で行われることが多く、作業者は両手を使う作業の合間に作業記録も残すことが求められている。これは作業効率の低下だけでなく、記録の度に設備から目を離さなければならないので誤作業につながる。 Communication equipment work can be roughly divided into two. One is work such as operating a communication facility by command using an operation terminal, and this work can automatically record work time and work content. The other is manual work, visual confirmation, and the like, which generally do not leave work records because they are performed without using ICT equipment. Examples of the latter manual work include plugging/unplugging cables, fuses, packages, etc., and plugging/unplugging measuring instruments. Examples of visual confirmation include confirmation of lamps and various lock states. These works are often carried out on site, and workers are required to keep work records in between works that use both hands. This not only reduces work efficiency, but also leads to erroneous work because the user must take his or her eyes off the equipment each time a record is made.
　特許文献１には、入力した画像、音声、テキストデータ等のマルチメディアデータを容易に対応付けして印刷、画像一覧等の作成ができるマルチメディア報告書作成装置および報告書作成方法が開示されている。 Patent Literature 1 discloses a multimedia report creation apparatus and report creation method that can easily associate multimedia data such as input images, voices, and text data to print and create an image list. there is
特開第２０００―２５９７５０号公報Japanese Unexamined Patent Publication No. 2000-259750
　特許文献１に記載の報告書作成方法を、通信設備の保守作業に適用して、テキスト情報と組み合わせたテーブルデータとして保存し、個別または一括した報告書として出力することが考えられる。具体的には、予め入力したテキストデータにしたがって、複数の画像データ／音声データの中から取得すべき画像／音声データを選び出して、テキスト情報と組み合わせたテーブルデータとして保存することが考えられる。しかしながら、特許文献１には、特定の保守作業が実行された作業時刻を抽出する方法が記載されていない。そのため、この方法では、ケーブル挿抜作業の挿抜時刻を読み取ることはできない。 It is conceivable to apply the report creation method described in Patent Document 1 to maintenance work for communication equipment, save table data combined with text information, and output individual or batch reports. Specifically, it is conceivable to select image/audio data to be acquired from a plurality of image data/audio data according to pre-input text data, and store the selected image/audio data as table data in combination with text information.

　図１は、本発明の実施形態である作業時刻記録システムの概念図である。
　作業時刻記録システム１０００は、作業時刻記録装置１００と、２つのタブレット端末１１０，１２０とがネットワークＮＷを介して通信可能に接続されている。タブレット端末１１０には、ヘッドセット１１１が接続されており、タブレット端末１２０には、ヘッドセット１２１が接続されている。また、作業時刻記録システム１０００は、ネットワークＮＷと独立して通信設備１３０を有している。通信設備１３０は、現場設備１３１と現場設備１３１を制御する制御端末１３２を有している。現場設備１３１は、ケーブル、測定器やランプを有し、ケーブルの挿抜、保守パーツ（パッケージ）の挿抜、測定器での計測やランプの目視確認などが行われる。 (embodiment)
FIG. 1 is a conceptual diagram of a work time recording system that is an embodiment of the present invention.
In the work time recording system 1000, a work time recording device 100 and two tablet terminals 110 and 120 are communicably connected via a network NW. A headset 111 is connected to the tablet terminal 110 , and a headset 121 is connected to the tablet terminal 120 . The work time recording system 1000 also has a communication facility 130 independently of the network NW. The communication equipment 130 has a field equipment 131 and a control terminal 132 for controlling the field equipment 131 . The field equipment 131 has a cable, a measuring device, and a lamp, and insertion/extraction of cables, insertion/extraction of maintenance parts (packages), measurement with a measuring device, visual confirmation of the lamp, and the like are performed.
　現場作業者は、現場設備１３１の保守作業を行う者であり、タブレット端末１１０及びヘッドセット１１１を所持する。遠隔指示者は、制御端末１３２を操作すると共に、現場作業者を遠隔で指示する者であり、タブレット端末１２０及びヘッドセット１２１を所持する。これにより、遠隔指示者と現場作業者とは、電話会議を行うことができる。つまり、遠隔指示者は、タブレット端末１２０に表示された手順書を確認しながら、制御端末１３２を操作しながら、現場作業者に音声で指示を出すことができる。また、現場作業者は、タブレット端末１１０に表示された手順書を確認しながら、遠隔指示者に音声で報告をすることができる。つまり、遠隔指示者と現場作業者とは、電話会議で、作業の指示・報告をこまめに発声し合う。 A field worker is a person who performs maintenance work on the field equipment 131 and possesses a tablet terminal 110 and a headset 111 . A remote instructor is a person who operates the control terminal 132 and remotely instructs the field worker, and has the tablet terminal 120 and the headset 121 . This allows the remote instructor and the field worker to have a conference call. That is, the remote instructor can issue instructions to the field worker by voice while operating the control terminal 132 while checking the procedure manual displayed on the tablet terminal 120 . In addition, the field worker can make a report to the remote instructor by voice while confirming the procedure manual displayed on the tablet terminal 110 . In other words, the remote instructor and the on-site worker frequently utter work instructions and reports to each other in a teleconference.
　なお、電話会議では、タブレット端末１１０が送信する音声信号Ｐ０は、作業時刻記録装置１００を介してタブレット端末１２０に送信される。つまり、作業時刻記録装置１００は、タブレット端末１１０が送信する音声信号Ｐ０をリアルタイムに受信する。また、手順書とは、保守作業全体の作業内容・作業対象・工程番号が列挙されたもので、工事前に作成される。 In the conference call, the audio signal P0 transmitted by the tablet terminal 110 is transmitted to the tablet terminal 120 via the work time recording device 100. That is, the work time recording device 100 receives the audio signal P0 transmitted by the tablet terminal 110 in real time. In addition, the procedure manual lists the work contents, work targets, and process numbers of the entire maintenance work, and is created before the construction work.
　なお、遠隔指示者と現場作業者とは、公衆回線を介して電話会議を行っても構わない。このときには、タブレット端末１１０が作業時刻記録装置として機能し、マイク又は電話機の受話器に接続されたピックアップを介して現場作業者の発話内容がリアルタイムに入力される。 It should be noted that the remote instructor and the field worker may hold a conference call via a public line. At this time, the tablet terminal 110 functions as a work time recording device, and the utterance content of the field worker is input in real time via a pickup connected to a microphone or telephone handset.
　図２は、本発明の実施形態である作業時刻記録装置のハードウェア構成図である。
　作業時刻記録装置１００は、揮発性記憶部２と、不揮発性記憶部３と、入力部としての通信部５と、表示操作部６と、音声信号入出力部７と、時計８と、制御部１０とを備えて構成される。なお、揮発性記憶部２と不揮発性記憶部３とで記憶部４を構成する。また、タブレット端末１１０，１２０も同様の構成である。 FIG. 2 is a hardware configuration diagram of a work time recording device that is an embodiment of the present invention.
The work time recording device 100 includes a volatile storage unit 2, a nonvolatile storage unit 3, a communication unit 5 as an input unit, a display operation unit 6, an audio signal input/output unit 7, a clock 8, and a control unit. 10. Note that the storage unit 4 is composed of the volatile storage unit 2 and the nonvolatile storage unit 3 . The tablet terminals 110 and 120 also have the same configuration.
　揮発性記憶部２は、ＲＡＭ(Random Access Memory)であり、ワーキングメモリとして使用される。不揮発性記憶部３は、ＲＯＭ(Read On Memory)であり、プログラム等が格納される。プログラムは、ネットワークＮＷ又は記録媒体９から通信部５を介して、不揮発性記憶部３に格納される。通信部５は、ネットワークＮＷと通信を行うインタフェースであり、音声信号を入力する入力部として機能する。表示操作部６は、例えば、タッチパネルディスプレイである。音声信号入出力部７は、マイクやスピーカを接続するインタフェースであり、タブレット端末１１０，１２０では、ヘッドセット１１１，１２１と接続される。時計８は、時刻を計時している。制御部１０は、ＣＰＵ（central processing unit）であり、プログラムを実行することにより各部を制御する。 The volatile storage unit 2 is RAM (Random Access Memory) and is used as working memory. The nonvolatile storage unit 3 is a ROM (Read On Memory) and stores programs and the like. The program is stored in the non-volatile storage unit 3 from the network NW or the recording medium 9 via the communication unit 5 . The communication unit 5 is an interface for communicating with the network NW, and functions as an input unit for inputting audio signals. The display operation unit 6 is, for example, a touch panel display. The audio signal input/output unit 7 is an interface that connects a microphone and a speaker, and is connected to the headsets 111 and 121 in the tablet terminals 110 and 120 . A clock 8 keeps time. The control unit 10 is a CPU (central processing unit) and controls each unit by executing a program.
　図３は、本発明の実施形態である作業時刻記録装置の機能構成図である。
　作業時刻記録装置１００は、前記したように、記憶部４と、時計８と、制御部１０とを備える。記憶部４には、手順書ファイル２０が格納される。手順書ファイル２０は、例えば、Ｅｘｃｅｌファイルであり、ＷＯＲＤファイル等でも構わない。制御部１０は、プログラムが実行されることにより、音声信号入力処理部１１と、音声認識部１２と、手順書データ取込部１３と、作業時刻分析部１４と、作業時刻記録部１５と、表示制御部１６との機能を実現する。 FIG. 3 is a functional configuration diagram of the work time recording device that is an embodiment of the present invention.
The work time recording device 100 includes the storage unit 4, the clock 8, and the control unit 10, as described above. A procedure manual file 20 is stored in the storage unit 4 . The procedure manual file 20 is, for example, an Excel file, and may be a WORD file or the like. By executing the program, the control unit 10 includes a voice signal input processing unit 11, a voice recognition unit 12, a procedure manual data acquisition unit 13, a work time analysis unit 14, a work time recording unit 15, A function with the display control unit 16 is realized.
　音声信号入力処理部１１は、通信部５（図２）に、タブレット端末１１０（図１）からの音声信号Ｐ０をリアルタイムに入力させる。また、音声信号入力処理部１１は、受信した音声信号Ｐ０と共に、時計８が計時した時刻情報ｔを、新たな音声信号Ｐ１として音声認識部１２に出力する。ここで、時刻情報ｔとは、一連の音声が発生している間の全時刻情報であり、音声の開始終了時刻だけではない。音声認識部１２は、音声信号入力処理部１１から入力した音声信号Ｐ１を音声認識（文字起こし）し、時刻情報ｔと共に、テキストＴで作業時刻分析部１４に出力する。音声信号Ｐ１は、各言葉が発せられた時刻情報を付した会話文（文章、文字起こし文）である。手順書データ取込部１３は、手順書ファイル２０を用いて、複数の作業の中から特定された特定作業（例えば、ケーブルの挿抜）の情報（例えば、現場作業者が発話するキーワード）を取り込む。 The audio signal input processing unit 11 causes the communication unit 5 (FIG. 2) to input the audio signal P0 from the tablet terminal 110 (FIG. 1) in real time. The audio signal input processing unit 11 also outputs the received audio signal P0 together with the time information t measured by the clock 8 to the audio recognition unit 12 as a new audio signal P1. Here, the time information t is all time information during the generation of a series of voices, and is not limited to the start and end times of voices. The speech recognition unit 12 speech-recognizes (transcribes) the speech signal P1 input from the speech signal input processing unit 11, and outputs it to the work time analysis unit 14 as a text T together with the time information t. The voice signal P1 is a conversational sentence (sentence, transcribed sentence) with time information when each word is uttered. The procedure manual data importing unit 13 uses the procedure manual file 20 to import information (for example, keywords uttered by field workers) of a specific operation (for example, cable insertion/extraction) specified from a plurality of operations. .
　作業時刻分析部１４は、音声認識部１２が音声認識したテキストＴから特定作業の発話内容（キーワード）を抽出し、作業時刻を出力する。作業時刻記録部１５は、作業時刻分析部１４が出力した作業時刻を手順書ファイル２０の所定領域に格納する。これにより、特定作業の作業時刻が所定領域に記録された手順書ファイル２０が作成される。つまり、作業時刻記録装置１００の入力は、「音声信号Ｐ０、時刻情報ｔ、手順書」であり、出力は「作業時刻」である。表示制御部１６は、表示操作部６（図２）を制御するものであるが、特に、タブレット端末１１０．１２０では、手順書ファイル２０のデータを表示操作部６に表示させる。 The work time analysis unit 14 extracts the utterance content (keyword) of the specific work from the text T voice-recognized by the voice recognition unit 12, and outputs the work time. The work time recording unit 15 stores the work time output by the work time analysis unit 14 in a predetermined area of the procedure manual file 20 . As a result, the procedure manual file 20 is created in which the work time of the specific work is recorded in a predetermined area. That is, the input of the work time recording device 100 is "audio signal P0, time information t, procedure manual", and the output is "work time". The display control unit 16 controls the display operation unit 6 (FIG. 2), and particularly in the tablet terminals 110 and 120, causes the display operation unit 6 to display the data of the procedure file 20. FIG.
　図４は、手順書ファイルの内容の一例を示す表である。
　手順書ファイル２０は、表形式のファイル（例えば、Excelファイル）であり、行方向（横方向）に「工程概要」欄２１、「工番」欄２２、「作業概要」欄２３、「ビル」欄２４、「作業対象」欄２５、「自動装置記録対象」欄２６、「開始時刻」欄２７、「作業時刻（挿抜）」欄２８、「終了時刻」欄２９を有している。ここで、「自動装置記録対象」欄２６は、作業時刻記録装置１００に作業時刻を記録させたいときの目印として機能する。 FIG. 4 is a table showing an example of the contents of a procedure manual file.
The procedure file 20 is a tabular file (for example, an Excel file), and in the row direction (horizontal direction), there are a "process overview" column 21, a "manufacturing number" column 22, a "work overview" column 23, and a "building". It has a column 24 , a “work target” column 25 , a “automatic device recording target” column 26 , a “start time” column 27 , a “work time (insertion/removal)” column 28 , and an “end time” column 29 . Here, the "automatic device recording target" column 26 functions as a mark when the work time recording device 100 is desired to record the work time.
　また、手順書ファイル２０は、列方向（縦方向）に、作業工程が時系列的に記載されている。例えば、行３１の工程概要「7.観測器接続」では、工番「7-1」において、「オシロスコープ接続」を「Pビル」の「CSM F架 G段目 H番」を対象にして作業することが記載されている。また、このオシロスコープ接続作業（特定作業）が記録「対象」にされており、その作業時刻１０時１２分５５秒７８が自動記録されている。このように、手順書ファイル２０には、「自動装置記録対象」欄２６が設けられており、作業時刻記録装置１００が作業時刻を自動で分析・記録させたい工程かどうかを判定することができるように構成されている。また、手順書ファイル２０には、「作業時刻（挿抜）」欄２８が設けられており、作業時刻記録装置１００がその工程の作業時刻を記録（追記）するように構成されている。 Also, in the procedure manual file 20, work processes are written in chronological order in the column direction (vertical direction). For example, in the process outline "7. Observation instrument connection" on line 31, in the work number "7-1", "Oscilloscope connection" is performed for "CSM F rack G stage H number" of "P building" It is stated that In addition, this oscilloscope connection work (specific work) is set as a recording "target", and the work time of 10:12:55.78 is automatically recorded. As described above, the procedure manual file 20 is provided with the "automatic device recording target" column 26, and the work time recording device 100 can automatically analyze and record the work time of the process or not. is configured as Further, the procedure file 20 is provided with a "work time (insertion/removal)" column 28, and the work time recording device 100 is configured to record (additionally) the work time of the process.
　また、行３２の工程概要「10.CTFで光レベル測定」では、３つの工番「10-1」，「10-2」，「10-3」に分割されている。行３３の工番「10-1」には、「CTF OUTケーブル抜去」作業を「Pビル」の「CTF X架 Y段目 Z番」を対象にすることが記載されている。また、光レベル測定作業（特定作業）が記録「対象」にされており、その作業時刻１３時４１分１６秒２１が自動記録されている。 In addition, the process outline "10. Light level measurement with CTF" on line 32 is divided into three production numbers "10-1", "10-2", and "10-3". The work number "10-1" on line 33 describes that the "CTF OUT cable removal" work is targeted at "CTF X rack Y row Z number" of "P building". In addition, the light level measurement work (specific work) is recorded as a "target", and the work time of 13:41:16.21 is automatically recorded.
　行３４の工番「10-2」には、「測定器接続」作業を「Pビル」の「CTF X架 Y段目 Z番」を対象にすることが記載されている。また、行３５の工番「10-3」には、「光レベル測定」作業を「Pビル」の「CTF X架 Y段目 Z番」を対象にすることが記載されている。これらの「測定器接続」作業及び「光レベル測定」作業は、記録「対象外」にされており、「作業時刻（挿抜）」欄２８が空欄である。 The work number "10-2" on line 34 states that the "measuring device connection" work is targeted at "CTF X rack Yth row Z number" in "P building". In addition, the work number "10-3" of line 35 describes that the "light level measurement" work is targeted at "CTF X rack Yth row Z number" of "P building". These "measuring device connection" work and "optical level measurement" work are recorded "out of scope", and the "work time (insertion/removal)" column 28 is blank.
　図５は、現場作業者が発話する発話フローを示すフローチャートである。
　発話フローとは、作業者が発話する定型のフローであり、作業種別ごとに定められる。なお、発話フローは、手順書に記載しないものであるが、手順書に記載しても構わない。
　まず、遠隔指示者は、工程番号（工番）を読み上げる（Ｓ１）。現場作業者は、遠隔指示者による作業指示を確認し（Ｓ２）、復唱を行う（Ｓ３）。そして、現場作業者は、作業対象の再確認（Ｓ４）、作業開始の宣言（Ｓ５）、カウントダウン（Ｓ６）を行い、作業実行と同時に発声を行う（Ｓ７）。さらに、現場作業者は、完了報告を行う（Ｓ８）。そして、遠隔指示者は、完了報告（Ｓ８）の復唱を行い（Ｓ９）、工程を終了する。 FIG. 5 is a flowchart showing an utterance flow uttered by a field worker.
An utterance flow is a standard flow of utterances by a worker, and is defined for each work type. Note that the speech flow is not described in the procedure manual, but may be described in the procedure manual.
First, the remote instructor reads out the process number (manufacturing number) (S1). The field worker confirms the work instruction given by the remote instructor (S2) and repeats it (S3). Then, the field worker reconfirms the work target (S4), declares the start of work (S5), counts down (S6), and utters a voice at the same time as the work is executed (S7). Furthermore, the field worker makes a completion report (S8). Then, the remote instructor repeats the completion report (S8) (S9) and ends the process.
　また、カウントダウン（Ｓ６）、作業実行と同時に発声（Ｓ７）、完了報告（Ｓ８）の何れかの段階で挿抜に失敗したら、Ｓ３に戻り、作業指示（Ｓ２）の復唱を行う（Ｓ３）。 Also, if the insertion/removal fails at any stage of the countdown (S6), vocalization at the same time as work execution (S7), and completion report (S8), the process returns to S3 and repeats the work instruction (S2) (S3).
　図６Ａ，図６Ｂは、作業動作と発生タイミングとの関係を示す発声ルールを規定する図である。図６Ａは、コネクタの抜去と発声内容との関係を規定し、図６Ｂは、コネクタの挿入と発声内容との関係を規定している。
　図６Ａにおいて、コネクタの接続状態では、発声内容「３，２，１」でカウントダウンを行い、コネクタを抜去すると同時に「抜去」と発声することにし、抜去状態で「抜去しました。」と発声することにしている。図６Ｂにおいて、コネクタの抜去状態では、発声内容「３，２，１」でカウントダウンを行い、挿入すると同時に「挿入」と発声することにし、接続状態で「挿入しました。」と発声することにしている。 6A and 6B are diagrams defining vocalization rules showing the relationship between work motions and occurrence timings. FIG. 6A defines the relationship between connector removal and utterance content, and FIG. 6B defines the relationship between connector insertion and utterance content.
In FIG. 6A, in the connected state of the connector, the countdown is performed with the utterance content "3, 2, 1", and at the same time as the connector is pulled out, "removed" is uttered. I'm doing it. In FIG. 6B, when the connector is unplugged, a countdown is performed with utterance contents "3, 2, 1". ing.
　図７は、現場作業者および遠隔指示者が発話する発話内容の一例を示す図である。
　以下、図７を用いて、図５の発話フローを具体例を用いて説明する。
　遠隔指示者は、「続いて工番10番、CTFでの光レベル測定です。」と現場作業者に対して発話し、「工番10-1 CTF OUTケーブル抜去工程に入ります。」と、工程番号（工番）を読み上げ（Ｓ１）、「PビルCTFさんX架Y段目Z番OUT側ケーブルの示名条片を読み上げて下さい。」と発話する。なお、CTF（Cable Terminating Frame）とは、局内終端架のことである。 FIG. 7 is a diagram showing an example of utterance contents uttered by a field worker and a remote instructor.
The utterance flow of FIG. 5 will be described below using a specific example with reference to FIG.
The remote instructor said to the field worker, "Next is work number 10, light level measurement at CTF." Read out the process number (manufacturing number) (S1), and say, "Mr. P Building CTF, please read out the name strip of the Z number OUT side cable of the X rack Y stage." Note that CTF (Cable Terminating Frame) is an intra-office terminating frame.
　現場作業者は、「了解。示名条片読み上げます。・・(中略)・・、以上です。」と遠隔指示者に発話する。遠隔指示者は、「はい。示名条片に間違いありませんので、マーキングをして下さい。」と現場作業者に対して発話する。現場作業者は、「了解。・・・。はい。マーキング完了しました。」と遠隔指示者に対して発話する。 The on-site worker speaks to the remote instructor, "Understood. I will read out the signature strip... (Omitted)... That's it." The remote instructor utters to the field worker, "Yes. There is no mistake in the labeling strip, so please mark it." The field worker speaks to the remote instructor, "Understood....Yes. Marking is complete."
　遠隔指示者は、「マーキング完了、了解です。それではケーブル抜去に入ります。PビルCTFさん、周辺に注意して、今読み上げた」と発話すると共に、「X架CTF Y段Z番のケーブルを抜去して下さい。」と作業指示を現場作業者に出す（Ｓ２）。現場作業者は、「了解。X架Y段Z番のケーブルを抜去します。」と復唱を行い（Ｓ３）、「X架Y段Z番ポジションよし、マーキングよし。」と作業対象を再確認し（Ｓ４）、「はい。」、「それではケーブル抜去します。」と作業開始宣言を行い（Ｓ５）、「３，２，１」とカウントダウンを行い（Ｓ６）、作業実行と同時に「抜去！」と発声する（Ｓ７）。 The remote commander said, "Marking complete. Understood. Now, let's remove the cable. Mr. P Building CTF, pay attention to the surroundings and read it now." Please remove it." is issued to the field worker (S2). The field worker repeats, "Okay. I'm going to remove the cable from X rack Y row Z." (S4), "Yes.", "Then I will remove the cable." ” (S7).
　図８は、現場作業者が発話した音声信号に対して、文字認識を行う様子を示す図である。
　音声信号Ｐ０は、音声信号入力処理部１１（図３）の入力信号である。時刻情報ｔは、時計８（図３）が出力するものであり、音声信号Ｐ０に対応している。音声信号Ｐ１は、音声信号入力処理部１１（図３）の出力信号であり、音声信号Ｐ０に時刻情報ｔを付したものである。テキストＴは、音声信号Ｐ１を入力したときの音声認識部１２（図３）の認識結果である。なお、「抜去！」の発話時刻は、１３時４１分１６秒である。 FIG. 8 is a diagram showing how character recognition is performed on a voice signal uttered by a field worker.
The audio signal P0 is an input signal of the audio signal input processing section 11 (FIG. 3). The time information t is output by the clock 8 (FIG. 3) and corresponds to the audio signal P0. The audio signal P1 is an output signal of the audio signal input processing section 11 (FIG. 3), and is obtained by adding time information t to the audio signal P0. The text T is the recognition result of the speech recognition unit 12 (FIG. 3) when the speech signal P1 is input. Note that the utterance time of "Remove!" is 13:41:16.
　図９は、文字認識結果と発話時刻との対応関係を示す図である。
　文字認識結果は、例えば、カウントダウン「３，２，１」及び「抜去！」である。「３」の発話時刻が１３時４１分１２秒０３であり、「２」の発話時刻１３時４１分１３秒３９であり、「１」の発話時刻が１３時４１分１４秒８３である。また、「抜去！」の発話時刻が１３時４１分１６秒２１である。作業時刻分析部１４は、この「抜去！」の発話時刻を特定作業の作業時刻と決定する。 FIG. 9 is a diagram showing the correspondence between character recognition results and utterance times.
Character recognition results are, for example, countdown "3, 2, 1" and "Withdraw!". The utterance time of "3" is 13:41:12.03, the utterance time of "2" is 13:41:13.39, and the utterance time of "1" is 13:41:14.83. Also, the utterance time of "Remove!" is 13:41:16:21. The work time analysis unit 14 determines the utterance time of "Remove!" as the work time of the specific work.
　図７の説明に戻り、現場作業者は、「抜去しました。」と完了報告を行う（Ｓ８）。
　遠隔指示者、「抜去完了了解です。」と復唱を行うと共に（Ｓ９）、「アラーム状態確認しますのでそのままお待ちください。」、「はい、異常アラームありません。」、「PビルCTFさんは抜去したケーブルの養生をして下さい。」と現場作業者に対して発話する。現場作業者は、「了解です。ケーブルの養生をします。終わりましたら発声します。お待ち下さい。」と遠隔指示者に発話する。 Returning to the description of FIG. 7, the site worker reports completion by saying, "Removed." (S8).
The remote instructor repeats, "I understand that removal has been completed." Please take care of the cable." to the field worker. The field worker utters to the remote instructor, "Understood. I will cover the cable. I will speak when finished. Please wait."
　以上説明したように、本実施形態の作業時刻記録システム１０００（図１）では、通信設備１３０の工事において、遠隔指示者と現場作業者とが電話会議を用いて、指示と報告とのやり取りが行われる。また、工事では、必ず作業手順書（手順書ファイル２０）が存在し、その作業手順書にしたがって作業が行われる。本実施形態の作業時刻記録装置１００では、電話会議の音声信号Ｐ０（図１，３）と手順書上の文字情報を統合的に分析することで、リアルタイムに作業時刻が手順書ファイル２０の所定領域に記録される。これにより、作業時刻記録システム１０００では、装置等から目や手を離さなくてよくなり、誤作業の撲滅や作業の安全性の向上が期待できる。また、遠隔指示者や工事監督者は、工事の途中でもその工程までの工事の進捗を把握できるようになる。また、遠隔指示者や工事監督者は、時刻情報ｔを利活用することで、例えば工事の改善を図ることもできる。なお、作業時刻記録システム１０００の内部に、カメラなどの追加デバイスを現場に新規導入する必要がない。 As described above, in the work time recording system 1000 (FIG. 1) of the present embodiment, in the construction of the communication equipment 130, the teleconference is used between the remote instructor and the field worker to exchange instructions and reports. done. Further, in construction work, there is always a work procedure manual (procedure manual file 20), and the work is carried out according to the work procedure manual. In the work time recording device 100 of this embodiment, by comprehensively analyzing the audio signal P0 (FIGS. 1 and 3) of the teleconference and the character information on the procedure manual, the work time is recorded in the procedure manual file 20 in real time. recorded in the area. As a result, in the work time recording system 1000, the user does not need to take his/her eyes or hands away from the device, etc., and it is expected that erroneous work will be eradicated and work safety will be improved. Also, the remote instructor and the construction supervisor can grasp the progress of the construction up to the process even during the construction. Also, the remote instructor and the construction supervisor can improve the construction, for example, by utilizing the time information t. It should be noted that there is no need to newly introduce an additional device such as a camera to the site inside the work time recording system 1000 .
（比較例）
　前記実施形態の作業時刻記録システム１０００（図１）では、作業時刻記録装置１００が現場作業者による特定作業の作業時刻を、現場作業者の発話内容に基づいて、手順書ファイル２０の所定領域に自動的に格納（追記）していた。比較例の作業時刻記録システム１００１では、現場作業者が作業時刻を手作業で手順書ファイル２０の所定領域に格納したり、メモ書きしたりする。 (Comparative example)
In the work time recording system 1000 (FIG. 1) of the above-described embodiment, the work time recording device 100 records the work time of the specific work performed by the site worker in a predetermined area of the procedure file 20 based on the content of the field worker's utterance. It was automatically stored (appended). In the work time recording system 1001 of the comparative example, the field worker manually stores the work time in a predetermined area of the procedure manual file 20 or writes it down.
　図１０は、本発明の比較例である作業時刻記録システムの概念図である。
　作業時刻記録システム１００１は、２つのタブレット端末１１０，１２０がネットワークＮＷを介して通信可能に接続されている。つまり、作業時刻記録システム１００１（図１０）では、作業時刻記録装置１００（図１）を有していない。また、作業時刻記録システム１００１は、ネットワークＮＷと独立して通信設備１３０を有している。 FIG. 10 is a conceptual diagram of a work time recording system that is a comparative example of the present invention.
In the work time recording system 1001, two tablet terminals 110 and 120 are communicably connected via a network NW. In other words, the work time recording system 1001 (Fig. 10) does not have the work time recording device 100 (Fig. 1). The work time recording system 1001 also has a communication facility 130 independently of the network NW.
　作業時刻記録システム１００１では、前記実施形態と同様に、遠隔指示者と現場作業者とがヘッドセット１１１，１２１を用いて、図７の発話を行いながら保守作業を行う点で共通する。しかしながら、現場作業者は、発話内容「抜去！」（Ｓ７（図７））のタイミングで、時計を確認し、特定作業の作業時刻を手順書ファイル２０の所定領域に手作業で格納する。また、現場作業者は、作業時刻をメモ書きし、事後的に、手順書ファイル２０の所定領域に手作業で格納することもある。 In the work time recording system 1001, as in the above embodiment, the remote instructor and the field worker use headsets 111 and 121 to perform maintenance work while uttering the utterances shown in FIG. However, the field worker checks the clock at the timing of the utterance content "remove!" Also, the site worker may write a memo of the work time and manually store it in a predetermined area of the procedure manual file 20 afterwards.
　比較例の作業時刻記録システム１００１の場合、現場作業者などが作業時刻のメモを取る業務を担うことになる。しかしながら、現場作業者は、作業に両手を使うことや装置から目を離さないことが求められる。つまり、現場作業者は、例えばケーブル挿抜や刻々と変化するランプ状況の報告中に作業時刻の記録のために記録簿／ＰＣに目を移して時刻を記録することは困難である。このため、ヘッドセット１１１，１２１を用いて現場作業者が現場作業の実行状況を細かく遠隔指示者に伝えて、遠隔指示者が作業時刻の記録を取ったりしていた。 In the case of the work time recording system 1001 of the comparative example, a field worker or the like is in charge of taking notes of the work time. However, field workers are required to use both hands and keep an eye on the equipment. In other words, it is difficult for field workers to turn their attention to the record book/PC and record the time to record the working time, for example, while plugging/unplugging a cable or reporting a constantly changing lamp condition. For this reason, field workers used the headsets 111 and 121 to tell the remote instructor in detail about the execution status of field work, and the remote instructor kept a record of the work time.
　それに対して、作業時刻記録システム１０００では、作業時刻が自動記録されるので、その業務から解放され他の業務に時間を割いたり集中できたり、装置等から目や手を離さなくてよくなる。また、比較例の作業時刻記録システム１００１の場合、工事後に作業者が作業時刻を報告したりしていた。これに対し、作業時刻記録システム１０００では、工事の途中でもその工程までの工事の進捗を把握できるようになる。 On the other hand, the work time recording system 1000 automatically records the work time, so that the worker is freed from the task and can devote time or concentrate on other tasks, and does not need to take his/her eyes or hands off the device. Moreover, in the case of the work time recording system 1001 of the comparative example, the worker reports the work time after the construction work. On the other hand, with the work time recording system 1000, it is possible to grasp the progress of the construction up to the process even in the middle of the construction.
