Description
本発明は、原子力発電所などの点検および保守作業を行うときに、運転から隔離した配管設備にするために該当する弁の開閉操作し、隔離タグをその弁に付けた後の点検を支援するシステムに関する。 The present invention supports the inspection after opening and closing the valve and attaching the isolation tag to the valve to make the piping facility isolated from the operation when performing inspection and maintenance work of a nuclear power plant, etc. About the system.
従来、図6に示すように原子炉1の弁点検のシステムは、弁の開閉状態などの系統構成が記載されている系統構成台帳4と、点検作業時に弁の隔離状態を記載した隔離タグ31を管理、作成する計算機による作業管理システム3とにより点検作業を行う。 Conventionally, as shown in FIG. 6, the valve inspection system of the nuclear reactor 1 includes a system configuration ledger 4 in which the system configuration such as the open / close state of the valve is described, and an isolation tag 31 in which the isolation status of the valve is described during the inspection work. Inspection work is performed by a work management system 3 using a computer that manages and creates
点検作業の際は、作業管理システム3によって点検作業箇所に対応する隔離タグ31が発行され、作業員(運転員)は、その隔離タグ31を携帯して点検作業箇所へ行く。そして、点検作業箇所を分離する弁(隔離弁)2に隔離タグ31を取り付けた後に、その弁を閉操作して点検作業箇所を隔離状態にして作業を行う。 At the time of the inspection work, the work management system 3 issues an isolation tag 31 corresponding to the inspection work location, and the worker (operator) carries the isolation tag 31 and goes to the inspection work location. And after attaching the isolation tag 31 to the valve (isolation valve) 2 which isolate | separates an inspection work location, the valve | bulb is closed and an inspection work location is made into an isolation state, and it works.
点検作業後は、作業員は、系統構成台帳4からチェックすべき全ての弁の系統別チェックシート(以降チェックシートと略す)42を抜き出し、そのチェックシート42に従い、原子炉1内の弁に取り付けられた隔離タグ31の場所に行く。 After the inspection work, the worker extracts a check sheet 42 for each valve to be checked (hereinafter abbreviated as a check sheet) 42 from the system configuration register 4 and attaches it to the valves in the reactor 1 according to the check sheet 42. Go to the place of the isolation tag 31.
そして、作業員は該当する弁の前に来ると、まずチェックシート42にある弁の番号と弁銘板とを照合し、一致していればチェックシート42に基づいて必要な開閉操作を行い、系統構成を本来の状態に戻して、隔離タグ31を弁2から取り外す。そしてチェックシートに各作業の完了記録等を記入する。この作業を該当するすべての弁について行い、作業を完了する。 When the worker comes in front of the corresponding valve, first, the valve number on the check sheet 42 and the valve nameplate are checked, and if they match, the necessary opening / closing operation is performed based on the check sheet 42. The configuration is returned to the original state, and the isolation tag 31 is removed from the valve 2. Then, record the completion of each work on the check sheet. Complete this task for all applicable valves.
以上の作業では、まず作業管理システムからの多くの隔離タグを該当する弁のある箇所まで携帯しなければならず、落としたりして紛失したり、該当する隔離タグを探すなどに時間が掛かる。 In the above work, first, many isolation tags from the work management system must be carried to the location where the corresponding valve is located, and it takes time to drop or lose it or to search for the corresponding isolation tag.
点検作業後は、膨大な系統構成台帳より該当する弁のチェックシートをすべて抜き出さなければならないため時間が掛かり、その際に誤って別のシートを抜き出す可能性がある。また、作業員は、そのチェックシート内に記載されている弁の状態を読んで把握しなければならないため時間が掛かり、また把握ミスを犯す可能性がある。 After the inspection work, it takes time because all the check sheets of the corresponding valve must be extracted from a huge system configuration ledger, and in that case, another sheet may be accidentally extracted. Moreover, since the worker must read and grasp the state of the valve described in the check sheet, it takes time and may make a grasp mistake.
これらのミスや時間が掛かる欠点を解消するため作業員は、非常な負担とミスを犯さない努力と細心の注意が必要になっている。 In order to eliminate these mistakes and time-consuming drawbacks, workers are required to be extremely burdensome, effortless to make mistakes and careful attention.
一方、特許文献1には、原子力発電プラントなどの大規模な事業所の作業時に、作業員に携帯式通信装置を携行させ、作業員は、必要に応じてホストコンピュータと通信してデータを取り出し、携帯式通信装置の出力画面上に、自分の現在位置を表示したり、目的とする設備の位置を表示して、現在位置あるいは任意の位置から目的とする設備の位置への移動ルートを表示したりして、事業所内を移動する作業員あるいは作業員を監督する管理者に対し、有用なガイダンスを提供する情報システムが記載されている。
しかしながら、この特許文献に記載の技術は、弁点検に関するものではなく、いかに発電所の運転計画と協調をとって効率的かつ安全に実施するかが問題となる。
However, the technique described in this patent document does not relate to valve inspection, but how to implement it efficiently and safely in cooperation with the operation plan of the power plant.
本発明は上述のかかる事情に鑑みてなされたものであり、原子炉内などの配管の補修・点検作業において当該作業箇所を隔離するための弁の点検作業等を効率的かつ安全に行うことのできる弁点検支援システムを提供することを目的とする。 The present invention has been made in view of the above-mentioned circumstances, and is capable of efficiently and safely performing inspection work of a valve for isolating the work location in pipe repair and inspection work in a nuclear reactor or the like. It aims at providing the valve check support system which can be done.
上記目的を達成するため、本発明に係わる弁点検支援システムは、弁、電源等の作業対象設備の位置情報を含む系統構成データおよび作業対象設備の作業状況データを保存するデータベースと、作業状況データをもとに隔離弁あるいは隔離範囲内であるか否かという隔離状態を判定する作業管理システムと、隔離状態と系統構成データに基づいて作業計画を作成する系統構成管理システムと、隔離状態を記憶させたICチップを装備させた隔離タグと、隔離タグに保存されている隔離状態を取得し作業状況データを送信する携帯端末と、携帯端末から送られてくるデータをもとにデータベースの作業状況データを更新する手段と、を備えたことを特徴とする。 In order to achieve the above object, a valve inspection support system according to the present invention includes a database for storing system configuration data including position information of work target equipment such as valves and power supplies, and work status data of the work target equipment, and work status data.

本発明では、作業管理システムによって隔離状態を管理する一方、運転を行うための系統状態を管理する系統構成管理システムによって、この隔離状態と系統状態をもとに作業順序を作成するので、常に作業と運転のベースとなるデータを一元管理することができ作業ミスや不測の事故を防止することができる。 In the present invention, while the isolation state is managed by the work management system, the work sequence is created based on the isolation state and the system state by the system configuration management system that manages the system state for operation. Data that is the basis of driving can be centrally managed, and work mistakes and unexpected accidents can be prevented.
好ましくは、系統構成管理システムは、系統構成データをもとに作業位置近傍の作業対象設備の候補を抽出し、隔離状態をもとに作業対象設備および作業順序を決定する優先順位判定手段を備えるようにすると良い。 Preferably, the system configuration management system includes priority order determination means for extracting work target equipment candidates near the work position based on the system configuration data and determining the work target equipment and the work order based on the isolation state. It is good to do so.
すなわち、弁点検作業を行うにあたって、弁銘板作成時に系統構成管理システムにより弁銘板に取り付けたICチップに弁のデータを記憶させて弁に弁銘板を装着し、作業管理システムで作業を行う弁の隔離状況を表記および記憶させたICチップ付隔離タグを設け、点検作業時に作業管理システムから作業内容を、系統構成管理システムから弁の系統構成と弁の点検順番を携帯端末に取り込み、作業員は、携帯端末に表示される点検順番に従って作業を行う。 In other words, when performing valve inspection work, the valve data is stored in the IC chip attached to the valve nameplate by the system configuration management system when the valve nameplate is created, and the valve nameplate is attached to the valve. An isolation tag with an IC chip that indicates and stores the isolation status is provided, the work content is taken from the work management system at the time of inspection work, the system configuration of the valve and the inspection order of the valve are taken into the mobile terminal from the system configuration management system, Work according to the inspection order displayed on the mobile terminal.
特に、系統構成データは、作業対象設備間の移動時間を含み、優先順位判定手段は、当該移動時間に基づいて作業順序を決定すると共に携帯端末へ移動ルート情報を送信することによって、効率的に作業を行うことができる。 In particular, the system configuration data includes the travel time between the work target facilities, and the priority determination means efficiently determines the work order based on the travel time and transmits the travel route information to the mobile terminal. Work can be done.
なお、移動ルートを表示する際、同時に緊急時の非難ルートも表示することによって作業員の注意を喚起して不測の事態に備えることができる。 In addition, when displaying a movement route, it is possible to alert an operator and prepare for an unexpected situation by simultaneously displaying an emergency blame route.
また、本発明に係る弁点検支援システムは、作業管理システムは、携帯端末へ作業対象設備の隔離状態を送信し、携帯端末は、作業管理システムから送られてくる隔離状態を受信して、当該受信した隔離状態と、隔離タグに保存されている隔離状態とを照合して、その照合結果を該携帯端末上へ表示することを特徴とする。 Further, in the valve inspection support system according to the present invention, the work management system transmits the isolation state of the work target facility to the mobile terminal, and the mobile terminal receives the isolation state sent from the work management system, and The received quarantine state and the quarantine state stored in the quarantine tag are collated, and the collation result is displayed on the portable terminal.

In particular, since the work management system manages the isolation state of the valve, an IC chip may be provided on the valve nameplate and the isolation state may be written to the IC chip via a portable terminal.
本発明によれば、隔離状態や系統構成を一元管理するので、弁の点検作業を効率的かつ安全に行うことができる。 According to the present invention, since the isolation state and system configuration are centrally managed, the valve inspection work can be performed efficiently and safely.
以下、本発明の実施の形態を説明する。図1は、第1の実施の形態による弁点検支援システム10の構成図である。 Embodiments of the present invention will be described below. FIG. 1 is a configuration diagram of a valve inspection support system 10 according to the first embodiment.
この図で、原子炉1内の弁2を点検支援するシステムとして、所内LANで結合される計算機での作業票管理や隔離タグを作成などの隔離状況編集や隔離種別設定を行う計算機により作業管理システム3と、系統構成データを管理し、作業の優先順位を指示する同じく計算機による系統構成管理システム4Aと、これらの計算機やシステムのデータベースとなるデータベースを管理するファイル管理システム7とが所内LANで結合され、ファイル管理システム7と無線LANで結合され、弁点検を行う作業員5が携帯し、系統構成データの入力や弁やその電源の隔離状況の検索などをする携帯端末6と、この端末で記憶されたデータを読み込むことができる弁データを記憶している非接触ICチップを埋め込まれた弁銘板21Aと、隔離状況データを記憶している同じく非接触ICチップが埋め込まれた隔離タグ31Aでシステムは構成される。 In this figure, as a system to support inspection of the valve 2 in the reactor 1, work management is performed by a computer that performs isolation status editing such as creation of isolation tags and isolation type settings such as work sheet management and isolation tag creation by a computer connected by a local LAN. The system 3, the system configuration management system 4A that manages the system configuration data and instructs the priority of work, and the file management system 7 that manages the database that is the database of these computers and the system are connected to the local LAN. A portable terminal 6 that is coupled with the file management system 7 via a wireless LAN and is carried by a worker 5 who performs valve inspection and inputs system configuration data and searches for the isolation status of valves and their power sources, and the terminal. A valve nameplate 21A embedded with a non-contact IC chip storing valve data capable of reading the data stored in the System isolation tag 31A similarly contactless IC chip storing data is embedded is configured.
次に、図2〜4を用いて上記の構成を有する弁点検支援システム10の作用を説明する。図2は、システム全体のデータおよび作業手順の流れの説明図であり、図3は、データの流れ図である。 Next, the operation of the valve inspection support system 10 having the above configuration will be described with reference to FIGS. FIG. 2 is an explanatory diagram of the flow of data and work procedures of the entire system, and FIG. 3 is a data flow diagram.
系統構成管理システム4Aにより弁銘板21Aを作成するときに、これに取り付けられたICチップ22に弁の名称や番号および機能などの弁データを記憶させ、その弁銘板21Aを該当の弁2に装着する。作業管理システム3では、後述する隔離タグ31Aを発行するとき、隔離状況データを印刷するとともに、隔離タグ31Aの内蔵するICチップ32に隔離状況データを記憶させる。 When the valve nameplate 21A is created by the system configuration management system 4A, the valve data such as the valve name, number and function is stored in the IC chip 22 attached to the valve nameplate 21A, and the valve nameplate 21A is attached to the corresponding valve 2. To do. In the work management system 3, when the isolation tag 31A described later is issued, the isolation status data is printed, and the isolation status data is stored in the IC chip 32 built in the isolation tag 31A.
点検作業前の準備として、まず系統構成管理システム4A経由でファイル管理システム(データベース)7内の系統構成データ7aより点検する弁群の構成データを無線LAN経由で携帯端末(以降PDAと略す)6に入力するとともに、弁の点検順序や点検ルートの優先順位データも入手する。この入手した弁のデータをPDA6から作業管理システム3に送信し、作業管理システム3経由でファイル管理システム7の作業管理データ7bより該当する弁の隔離状況データをPDA6に入手する。すなわち、隔離タグ31Aがすでに取り付けられた既隔離中の弁か、今回隔離操作と隔離タグ31Aを装着する弁かなどの隔離状況データを無線LAN経由でPDA6に入力する。そして、今回隔離する弁については、隔離タグ31Aを作業管理システム3から発行させ点検作業時に持参する。このとき、上記したように隔離タグ31AのICチップ32に隔離状況データを記憶させる。以上で点検作業の準備を完了する。ここで、作業管理データ7bのデータ構成の一例を図5に示す。弁や電源などの作業対象設備の識別情報(弁・電源番号)ごとにその位置や作業標番号、作業期間、隔離状態を表した隔離種別、作業内容などが関連付けられて保存されている。また、系統構成データは、図示しないが各作業対象設備の接続状態や位置情報、平均の移動時間等が保存されている。 As preparations before the inspection work, first, the configuration data of the valve group to be inspected from the system configuration data 7a in the file management system (database) 7 via the system configuration management system 4A is transmitted to the portable terminal (hereinafter abbreviated as PDA) 6 via the wireless LAN. In addition, the priority order data of the valve inspection sequence and inspection route is also obtained. The obtained valve data is transmitted from the PDA 6 to the work management system 3, and the relevant valve isolation status data is obtained from the work management data 7 b of the file management system 7 via the work management system 3. That is, the isolation status data such as whether the isolation tag 31A is already attached or the isolation operation and the isolation tag 31A are installed is input to the PDA 6 via the wireless LAN. For the valve to be isolated this time, the isolation tag 31A is issued from the work management system 3 and is brought to the inspection work. At this time, the isolation status data is stored in the IC chip 32 of the isolation tag 31A as described above. This completes the preparation for inspection work. Here, an example of the data structure of the work management data 7b is shown in FIG. For each piece of identification information (valve / power supply number) of work target equipment such as a valve and a power source, the position, work number, work period, isolation type representing the isolation status, work content, and the like are associated and stored. In addition, although not shown, the system configuration data stores the connection status and position information of each work target facility, the average travel time, and the like.
作業員5は、必要な弁2のデータを記憶したPDA6と発行した隔離タグ31Aを携帯して優先順位データに従い、最初の今回隔離する弁2に向かう。該当する弁2の近くに来たら、弁銘板21Aを目視で確認するとともに、弁銘板21AのICチップ22からのデータをPDA6によって読み取り、PDA6の表示器により目視で確認するとともに、点検する弁か否かをPDA6内の弁データとICチップ32の弁データを照合することによって自動的に判定させる。そして、両データが不一致の場合、PDA6より警報表示を行う。 The worker 5 carries the PDA 6 storing the necessary valve 2 data and the issued isolation tag 31 </ b> A and follows the priority order data to the first valve 2 to be isolated this time. When the valve 2 comes close to the corresponding valve 2, the valve name plate 21A is visually confirmed, the data from the IC chip 22 of the valve name plate 21A is read by the PDA 6, visually confirmed by the display of the PDA 6, and the valve to be checked. It is determined automatically by comparing the valve data in the PDA 6 with the valve data of the IC chip 32. If the two data do not match, an alarm is displayed from the PDA 6.
作業員は、この確認後、弁2への必要な操作を行い、携帯してきた該当する弁の隔離タグ31Aを印刷された文字で確認して弁に装着する。そして、再度隔離タグ31AのICチップ32の内容をPDA6によって読み取り、PDA6の表示器と弁データとの照合を実行する。そして、不整合時は、PDA6に警報表示する。 After this confirmation, the operator performs necessary operations on the valve 2, confirms the isolation tag 31A of the corresponding valve that has been carried with printed characters, and attaches it to the valve. Then, the content of the IC chip 32 of the isolation tag 31A is read again by the PDA 6, and collation between the display device of the PDA 6 and the valve data is executed. When there is a mismatch, an alarm is displayed on the PDA 6.
最後にこの弁への作業が完了した旨をPDA6に入力し、作業管理システム3へ所内LAN経由で通知する。この完了が通知されると、系統構成管理システム4Aは、次の弁へのナビゲーションをPDA6の表示器に表示し、作業員はその指示に従って次の点検作業する弁に向かい、上述の弁点検処理を繰り返す。すべての点検作業すべき弁の作業が終了したら、その旨PDA6より入力して作業管理システム3に通知する。 Finally, the fact that the work on the valve is completed is input to the PDA 6 and notified to the work management system 3 via the local LAN. When this completion is notified, the system configuration management system 4A displays the navigation to the next valve on the display of the PDA 6, and the worker goes to the valve for the next inspection work according to the instruction, and the above-described valve inspection processing is performed. repeat. When the work of all the valves to be inspected is completed, a message to that effect is input from the PDA 6 and notified to the work management system 3.
図4にナビゲーションのための優先順位判定の処理手順について、点検作業後の系統構成復元時の作業を例に説明する。まず現在位置の弁番号と現在地をPDA6に入力する(S101)。この入力は、作業員が手入力によって行っても良いし、弁銘板に当該銘板の識別情報を保存したICチップを持たせ、PDA6によってこのICチップの情報を読み込むことによって弁位置を特定するようにしても良い。 FIG. 4 illustrates a procedure for determining the priority order for navigation, taking as an example the work at the time of system configuration restoration after inspection work. First, the valve number of the current position and the current location are input to the PDA 6 (S101). This input may be performed manually by an operator, or the valve name plate is provided with an IC chip storing identification information of the name plate, and the valve position is specified by reading the information of the IC chip by the PDA 6. Anyway.
そしてファイル管理システム7の系統構成データ7aと作業管理データ7bから入力した弁情報を取得し、この弁が作業中か否かを調べる(S102)。作業中でない場合は(S102で「YES」)、次に隔離弁以外か否かを判定し、隔離弁以外の場合は(S103で「YES」)、系統構成情報をファイル管理システム7へ入力し(S104)、その後、隔離弁以外の系統構成が完了したか否かを判定して(S105)、完了した場合は終了し、未完了の場合は、系統構成管理システム4Aによって現在地からも最も近い弁で隔離弁以外の弁を選択してPDA6へ送信し(S109)、ステップS102の処理へ移行する。 Then, the valve information input from the system configuration data 7a and the work management data 7b of the file management system 7 is acquired, and it is checked whether or not this valve is working (S102). If it is not in operation (“YES” in S102), it is next determined whether or not it is an isolation valve. If it is not an isolation valve (“YES” in S103), the system configuration information is input to the file management system 7. (S104) After that, it is determined whether or not the system configuration other than the isolation valve is completed (S105). If it is completed, it is terminated. If it is not completed, the system configuration management system 4A is closest to the current location. A valve other than the isolation valve is selected and transmitted to the PDA 6 (S109), and the process proceeds to step S102.
一方、ステップS102で作業中の場合は、作業管理システム3によって隔離状態や作業期間などの作業状況をPDA6の表示器に表示すると共に(S106)、系統構成管理システム4Aにより現在地からも最も近い弁で隔離弁以外の弁を選択して(S107)、ステップS102の処理に移行する。 On the other hand, when the work is being performed in step S102, the work management system 3 displays the work status such as the isolation state and the work period on the display device of the PDA 6 (S106), and the system configuration management system 4A also displays the closest valve from the current location. Then, a valve other than the isolation valve is selected (S107), and the process proceeds to step S102.
また、ステップS103で「NO」の場合は、隔離弁以外の系統構成が完了したか否かを判定し(S108)、完了した場合は(S108で「YES」)、ステップS104で系統構成情報を入力し、完了していない場合は(S108で「NO」)、ステップS109の処理へ移行する。以上の処理を隔離弁以外の系統構成が完了するまで続ける。 If “NO” in the step S103, it is determined whether or not the system configuration other than the isolation valve is completed (S108). If completed (“YES” in the S108), the system configuration information is obtained in a step S104. If the input has not been completed ("NO" in S108), the process proceeds to step S109. The above processing is continued until the system configuration other than the isolation valve is completed.
以上、本実施の形態によれば、弁点検作業を行う作業員が携帯端末を携帯することにより、作業管理システムと系統構成管理システムおよび弁銘板や隔離タグの取り付けられたICチップとの情報の授受を行うことによって、弁点検作業を効率よく、ミスなく行うことが可能となる。特に、両システム3,4Aによって点検作業前の隔離作業および点検作業後の系統構成復元作業をトータル的に管理し、それぞれ最適な移動ルートを演算して、作業者に指示することによって、各作業を円滑かつ確実に実施することができる。 As described above, according to the present embodiment, the worker who performs the valve inspection work carries the portable terminal, so that the information on the work management system, the system configuration management system, and the IC chip to which the valve nameplate and the isolation tag are attached are stored. By giving and receiving, it becomes possible to perform the valve inspection work efficiently and without mistakes. In particular, both systems 3 and 4A totally manage the isolation work before the inspection work and the system configuration restoration work after the inspection work, calculate the optimal movement route for each work, and give instructions to the operator. Can be carried out smoothly and reliably.
また、電子データで管理するため、データ加工が容易になる。たとえば、未実施箇所検索、任意の検索、帳票作成などを効率よく行うことができる。さらに、隔離タグが紛失しても携帯端末で弁・電源の状態(隔離中、系統構成実施状況)が簡単に確認できる。
Moreover, since data is managed with electronic data, data processing becomes easy. For example, it is possible to efficiently perform an unexecuted part search, arbitrary search, form creation, and the like. Furthermore, even if the isolation tag is lost, the state of the valve / power supply (during isolation, system configuration implementation status) can be easily confirmed on the mobile terminal.
本発明は、上記の実施の形態に限定されること無く、その要旨を逸脱しない範囲で種々変形して実施することができる。たとえば、図1では、ファイル管理システム7や系統構成管理システム4A、作業管理システム3を独立して構成しLANで接続するようにしたが、これらのシステムを独立したものとせず、一体として一つの計算機によって実現しても良いし、任意に機能分散して実現しても良い。 The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention. For example, in FIG. 1, the file management system 7, the system configuration management system 4 </ b> A, and the work management system 3 are configured independently and connected via a LAN. However, these systems are not independent and are integrated as one unit. It may be realized by a computer or may be realized by arbitrarily distributing functions.
本発明は、産業設備の保守点検の作業に利用することができる。 The present invention can be used for work for maintenance and inspection of industrial facilities.
