Description

本発明は、プラント設備における操作認証システムに関し、特に、公共ライフライン設備、例えば、電気、ガス、水道、下水道などのプラント設備において、設備操作をする運転員が携行するタグに予め入力した固有ＩＤに基づいて設備単位で運転員の操作権限認証を行い、かつその運転履歴をも記録してセーフティロック機能を有するようにしたプラント設備における操作認証システムに関するものである。   The present invention relates to an operation authentication system in a plant facility, and in particular, a unique ID previously input to a tag carried by an operator who operates the facility in a public lifeline facility, for example, a plant facility such as electricity, gas, water, and sewer The operation authorization system of the plant equipment which authenticates the operation authority of the operator in units of equipment and records the operation history and has a safety lock function.

従来、電気、ガス、水道、下水道などの公共ライフラインのプラント設備においては、設備単位で１台もしくは複数台の操作盤を設置し、この操作盤を予め定めた作業をする運転員が特定の操作を、必要に応じて各操作盤を操作、例えば、公共ライフラインの供給量の調節操作、供給或いは停止の操作をするようにしている。   Conventionally, in plant facilities for public lifelines such as electricity, gas, water supply, and sewerage, one or more operation panels are installed in units of equipment, and operators who perform predetermined operations on these operation panels are specified. The operation is performed on each operation panel as necessary, for example, an operation for adjusting a supply amount of a public lifeline, or an operation for supply or stop.

ところで、設備単位で設置している操作盤は、安全のためロックを掛けるようにはしているが、このロックを解除すれば誰でも自由に操作可能となり、さらにロック解除状態で各運転員がそれぞれ個別的に操作を行えるようにして、操作の利便性を図るようにしているが、該操作盤を誰が、いつ、どのような操作を行ったかのデータを全く記録していないか、又はごく一部を記録しているにすぎない。   By the way, although the operation panel installed in the unit of equipment is locked for safety, anyone can operate freely if this lock is released, and each operator can operate in the unlocked state. Each operation can be performed individually to improve the convenience of the operation. However, the operation panel does not record any data about who, when, and what operation, or very little. It is only recording the part.

また、通常１事業所内に操作盤は、その操作内容に応じて複数配置され、かつその作業内容によりその操作をする運転員を予め定め、操作の誤りを防止するようにして安全性を高めるようにしている。しかし事業所内に入り、かつ運転操作室に近づくことができれる人であれば、指定された運転員以外のどの作業員でも、例えば、担当者以外の操作権限のない作業員や部外者でも操作可能なため、慣れない作業員や新しい作業員が誤って操作盤を操作するという問題があった。
また、メンテナンス時や故障発生時などにおいても、操作盤の操作履歴が操作盤の制御側に保存されていないため、どの操作を、誰が、いつどのようにして行ったか、を後で確認することができず、故障原因の追及などに時間が掛かるという問題があった。 In addition, a plurality of operation panels are usually arranged in one office according to the operation content, and an operator who performs the operation is determined in advance according to the operation content, so as to prevent an operation error and improve safety. I have to. However, any person other than the designated operator, for example, a worker who has no operating authority other than the person in charge, or an outsider who is able to enter the office and access the operation room Since it was operable, there was a problem that an unfamiliar worker or a new worker accidentally operated the operation panel.
In addition, even during maintenance or when a failure occurs, the operation history of the operation panel is not saved on the control side of the operation panel, so it is necessary to confirm later which operation was performed by whom. There was a problem that it took time to investigate the cause of the failure.

本発明は、上記従来のプラント設備における操作盤の有する問題点に鑑み、設備単位で操作をする運転員の操作権限認証を、運転員が携行するタグの固有ＩＤに基づいて行い、かつその運転履歴を制御側に記録することにより操作ミス等を未然に防止し、これによりセーフティロック機能を有するようにしたプラント設備における操作認証システムを提供することを目的とする。   In view of the problems of the operation panel in the conventional plant equipment, the present invention performs the operation authority authentication of the operator who operates in units of equipment based on the unique ID of the tag carried by the operator, and the operation It is an object of the present invention to provide an operation authentication system in a plant facility which prevents an operation error and the like by recording a history on the control side, thereby having a safety lock function.

上記目的を達成するため、本発明のプラント設備における操作認証システムは、プラント設備を操作する操作盤に配設した赤外線発光器による発光赤外線の照射エリア内に運転員が入ったとき、当該運転員が携行する固有ＩＤを有するタグと、操作盤側に備えたタグＩＤの認証用データベースを有する認証コントローラとの間にて光及び電波にて送受信を行って、該タグの固有ＩＤを認証用データベースに基づいて位置ＩＤ及びタグＩＤを判定し、当該運転員の操作権限等を固有ＩＤより認証し、制御シーケンサにより操作盤の操作可能範囲を決定して操作盤の操作権限を付与或いは不可を選択して付与操作権限範囲内での操作を可能とすると共に、その操作履歴を記録するようにしたことを特徴とする。   In order to achieve the above object, the operation authentication system for a plant facility according to the present invention is configured such that when an operator enters an irradiation area of emitted infrared rays by an infrared emitter disposed on an operation panel for operating the plant facility, the operator Is transmitted and received between the tag having the unique ID carried by the user and the authentication controller having the tag ID authentication database provided on the operation panel side, and the unique ID of the tag is assigned to the authentication database. The position ID and tag ID are determined based on the above, the operation authority of the operator is authenticated from the unique ID, the operation sequence of the operation panel is determined by the control sequencer, and the operation panel operation authority is selected to be granted or disabled Thus, it is possible to perform an operation within the granted operation authority range and to record the operation history.

この場合において、認証用データベースに基づいて運転員の操作権限等を固有ＩＤより認証した結果を、各種操作を制御するようにした制御シーケンサにＬＡＮを通じて伝達することができる。   In this case, the result of authenticating the operator's operation authority and the like from the unique ID based on the authentication database can be transmitted through the LAN to a control sequencer that controls various operations.

また、１台の認証コントローラにより、事業所内の現場毎に配設された複数台の操作盤に、それぞれの操作権限を付与或いは不可を選択して付与し、各操作盤毎の操作履歴を記録するようにすることができる。   In addition, with one authentication controller, each operation panel is recorded with an operation history for each operation panel by assigning or disabling each operation authority to multiple operation panels installed at each site in the office.

By doing so, even if a plurality of operation panels are arranged for each site in the office, the operation panel control at each site can be individually performed by one authentication controller. .

以下、本発明のプラント設備における操作認証システムの実施の形態を、図面に基づいて説明する。   Hereinafter, an embodiment of an operation authentication system in a plant facility of the present invention will be described based on the drawings.

図１〜図３に、本発明のプラント設備における操作認証システムの一実施例を示す。
本発明のプラント設備における操作認証システムは、プラント設備に配設される操作盤には認証コントローラ（ＣＴＬ）１を配備し、この認証コントローラ（ＣＴＬ）１と、操作権限を有する運転員が携行するようにしたタグＴとより構成する。

また、操作盤Ｃには、設備の各種制御を可能とするためのスイッチ、コントロールレバー、計測計、モニター等を備えるとともに赤外線発光器３を配設する。 1 to 3 show an embodiment of an operation authentication system in a plant facility of the present invention.
In the operation authentication system for a plant facility according to the present invention, an authentication controller (CTL) 1 is provided on an operation panel arranged in the plant facility, and this authentication controller (CTL) 1 and an operator having an operation authority carry it. The tag T is configured as described above.
The tag T has a tag ID (unique ID) into which personal data such as department, name age, ownership qualification, and operation authority is input, and an operator (operator or operator) M1 carrying the tag T. , M2, M3,..., Mn approaches a certain distance within a certain range with respect to the operation panel C for operating the plant equipment, for example, by the infrared light emitter 3 disposed on the operation panel C. When entering or approaching the light receiving infrared light receiving area, the tag is transmitted and received between the authentication controller (CTL) 1 disposed on the operation panel side and the tag T by radio and radio waves via the antennas A1 and A2. The tag ID of T is read by the authentication controller 1, the unique ID of the tag is determined from the authentication database input in advance to the controller 1, the position ID and the tag ID are specified, and the operator's operation The control sequencer 2 determines the operable range of the operation panel C on the basis of the authentication result, selects whether to grant or prohibit the operation authority of the operation panel C by a specific operator, and gives the operation The operation within the authority range is made possible and the operation history is recorded.
In addition, the operation panel C is provided with a switch, a control lever, a measuring instrument, a monitor and the like for enabling various kinds of control of the equipment, and an infrared light emitter 3 is disposed.

なお、この認証コントローラ（ＣＴＬ）１による認証結果は、認証コントローラ１よりＬＡＮ等を通じて操作盤Ｃに付設した制御シーケンサ（ＳＱＣ）２に伝達するとともに、このタグＴ、操作盤に配設したコントローラＣＴＬ間の送受信は、光と無線信号とにて行うもので、認証コントローラ側の赤外線発光器３による発光赤外線（光信号）をタグＴにて受光し、かつタグＴの信号は、無線信号により受信器を介して認証コントローラ１側へ伝達されるようにする。   The authentication result by the authentication controller (CTL) 1 is transmitted from the authentication controller 1 to the control sequencer (SQC) 2 attached to the operation panel C through a LAN or the like, and the tag T and the controller CTL disposed on the operation panel. The transmission / reception is performed using light and a radio signal. The tag T receives light emitted from the infrared light emitter 3 on the authentication controller side, and the tag T signal is received by a radio signal. It is transmitted to the authentication controller 1 side through the device.

このタグＴ、認証コントローラ（ＣＴＬ）１間の無線通信は、特に限定されるものではないが、例えば、ＲＦＩＤ（Radio Frequency Identification（電波方式認識）。本明細書において、「ＲＦＩＤ」という。）にて行うことができる。   The wireless communication between the tag T and the authentication controller (CTL) 1 is not particularly limited. For example, RFID (Radio Frequency Identification) is referred to as “RFID” in this specification. Can be done.

なお、タグＴは運転員等が所持する場合、人が携行しやすい大きさ、形状とし、名札やバッチの如く形成して胸に装着するか、首から吊り下げるようにし、操作盤側からの発光赤外線を受光できるように構成するもので、これは特に限定されるものではないが、例えば、１つのケース内に、赤外線発光を受光できるようにした受光フォトダイオードと、この受光フォトダイオードにて受光した光信号を位置ＩＤに変換するようにした受信回路と、この位置ＩＤとタグＩＤ（固有ＩＤ）を合成するようにしたＩＤ合成回路と、合成ＩＤを電波、例えば、無線信号に合成する発信回路とより構成する。   If the tag T is carried by an operator, etc., the tag T should have a size and shape that can be easily carried by a person, formed like a name tag or batch, and worn on the chest, or suspended from the neck. It is configured to receive light emitting infrared rays, and this is not particularly limited. For example, in one case, a light receiving photodiode capable of receiving infrared light emission and a light receiving photodiode. A receiving circuit that converts a received optical signal into a position ID, an ID combining circuit that combines the position ID and a tag ID (unique ID), and a combined ID into a radio wave, for example, a radio signal. It consists of a transmission circuit.

また、認証コントローラ１は、図示省略したが、一般にＲＦＩＤとして使用されている構成を採用し、特に限定されるものではないが、例えば、位置ＩＤ生成回路及び認証判定回路からなる計算機ＣＰＵと、外部Ｉ／Ｏ制御回路と、前記位置ＩＤ生成回路にて形成された位置ＩＤの信号を光信号に変換するようにして位置ＩＤ生成回路に接続する光信号変換回路と、タグＩＤと位置ＩＤをキーにデータベースから認証結果を取得するよう認証判定回路に接続した認証用データベースと、認証判定回路と外部Ｉ／Ｏ制御回路の間に接続し、かつ操作盤の各種スイッチ類を制御するようにした制御回路、及び合成ＩＤを位置ＩＤとタグＩＤに変換するようにしたＩＤ変換回路とから構成する。   Although not shown, the authentication controller 1 adopts a configuration generally used as an RFID and is not particularly limited. For example, a computer CPU including a position ID generation circuit and an authentication determination circuit, and an external An I / O control circuit, an optical signal conversion circuit connected to the position ID generation circuit so as to convert the signal of the position ID formed by the position ID generation circuit into an optical signal, and the tag ID and the position ID as keys The authentication database connected to the authentication judgment circuit to acquire the authentication result from the database, and the control connected between the authentication judgment circuit and the external I / O control circuit and controlling various switches of the operation panel The circuit is composed of an ID conversion circuit that converts a combined ID into a position ID and a tag ID.

また、認証コントローラ１の光信号変換回路には、赤外線発光器３、例えば、赤外線発光ＬＥＤを接続して光信号変換回路からの位置ＩＤ信号を光信号に変換し赤外線を発光させ、固有ＩＤを有するタグＴを所持している運転員（作業者又は操作者）Ｍ１、Ｍ２、Ｍ３、・・・、Ｍｎが、前記赤外線発光器３の赤外線照射エリア内に侵入すると該タグＴにてこの赤外線信号を受光するように構成する。   The optical signal conversion circuit of the authentication controller 1 is connected to an infrared light emitter 3, for example, an infrared light emitting LED, converts the position ID signal from the optical signal conversion circuit into an optical signal, emits infrared light, and has a unique ID. When an operator (operator or operator) M1, M2, M3,..., Mn who has the tag T having the tag T enters the infrared irradiation area of the infrared light emitter 3, the infrared rays are emitted from the tag T. It is configured to receive a signal.

この赤外線発光器（赤外線発光ＬＥＤ）３は、１台の操作盤Ｃに対して少なくとも１つを配置するものとし、かつ運転員Ｍ１、Ｍ２、Ｍ３、・・・、Ｍｎのいずれか指定された一人の運転員が予め定めた位置に着座或いは近づいたとき、タグＴとの通信が行えるようにすると共に、操作盤Ｃが複数台隣接配置される場合には、互いに光による通信が混信しないよう、ある程度の指向性を有するものが望ましい。
また、操作盤Ｃが、例えば、図２に示すように、中央監視センターには複数台を隣接して配置され、また複数ある現場１、現場２、現場ｎには、それぞれの現場に各操作盤Ｃを配置されるような場合には、１台の認証コントローラ１と、各操作盤Ｃ、Ｃに配設された複数個の赤外線発光器（赤外線発光ＬＥＤ）３が接続されるようにする。 This infrared light emitter (infrared light emitting LED) 3 is arranged at least one for one operation panel C, and one of operators M1, M2, M3,..., Mn is designated. When one operator is seated or approaches a predetermined position, communication with the tag T can be performed, and when a plurality of operation panels C are arranged adjacent to each other, communication by light does not interfere with each other. Those having a certain degree of directivity are desirable.
Further, for example, as shown in FIG. 2, a plurality of operation panels C are arranged adjacent to the central monitoring center, and each of the operation sites C, 2 and n has a respective operation at each site. When the panel C is disposed, one authentication controller 1 and a plurality of infrared light emitters (infrared light emitting LEDs) 3 disposed on the operation panels C and C are connected. .

次に、本発明のプラント設備における操作認証システムの作用について説明する。
タグＴを所持しない者が赤外線発光器（赤外線発光ＬＥＤ）３の発光赤外線の受光エリア内の操作盤に近づいても、認証コントローラ１の赤外線発光器（発光ＬＥＤ）３からの赤外線を受光することができないので、認証コントローラ１側にて位置ＩＤ信号を受光できず、従ってこのような場合は認証コントローラ１側との通信が不能となり、制御シーケンサ（ＳＱＣ）２にて操作盤Ｃの制御を不能とする。
このため、制御盤Ｃに近づていも制御盤Ｃは操作することができない。これにより不正又は誤操作を防止することができる。 Next, the operation of the operation authentication system in the plant facility of the present invention will be described.
Even if a person who does not have the tag T approaches the operation panel in the light emitting infrared light receiving area of the infrared light emitting device (infrared light emitting LED) 3, the infrared light from the infrared light emitting device (light emitting LED) 3 of the authentication controller 1 is received. Therefore, the position ID signal cannot be received on the authentication controller 1 side. Therefore, in such a case, communication with the authentication controller 1 side becomes impossible and the control sequencer (SQC) 2 cannot control the operation panel C. And
For this reason, even if it approaches the control panel C, the control panel C cannot be operated. As a result, unauthorized or erroneous operations can be prevented.

また、正規のタグＴを所持した運転員Ｍ１、Ｍ２が、予め設定された認証コントローラＣＴＬの赤外線の受光エリア内に近づくと、当該操作盤Ｃには常時認証コントローラＣＴＬからの位置ＩＤが赤外線信号に変換されて赤外線発光器（発光ＬＥＤ）３から発光されているので、この発光に基づく位置ＩＤ信号をタグＴの受光フォトダイオードにて受光し、この光信号を受信回路にて位置ＩＤに変換し、次いでＩＤ合成回路により、この位置ＩＤとタグＩＤ（固有ＩＤ）を合成した合成ＩＤを発信回路よりアンテナＡ１、Ａ２を介して電波、例えば、無線信号にて発信する。   Further, when the operators M1 and M2 carrying the regular tag T approach the preset infrared receiving area of the authentication controller CTL, the position ID from the authentication controller CTL is always displayed on the operation panel C as an infrared signal. Since the infrared light emitting device (light emitting LED) 3 emits light, a position ID signal based on this light emission is received by a light receiving photodiode of the tag T, and this optical signal is converted into a position ID by a receiving circuit. Then, the ID combining circuit transmits a combined ID obtained by combining the position ID and the tag ID (unique ID) from the transmitting circuit via the antennas A1 and A2 by radio waves, for example, radio signals.

この無線信号となった合成ＩＤを受信器のアンテナＡ２にて受信し、その受信信号を認証コントローラＣＴＬ内の外部Ｉ／Ｏ制御回路に伝達する。この受信した合成ＩＤを認証コントローラＣＴＬ内のＩＤ変換回路にて解析し、合成ＩＤを位置ＩＤとタグＩＤ（固有ＩＤ）の信号に分解して認証判定回路に伝達する。   The combined ID that is the radio signal is received by the antenna A2 of the receiver, and the received signal is transmitted to the external I / O control circuit in the authentication controller CTL. The received composite ID is analyzed by an ID conversion circuit in the authentication controller CTL, and the composite ID is decomposed into a signal of a position ID and a tag ID (unique ID) and transmitted to the authentication determination circuit.

この認証判定回路では、タグＩＤと位置ＩＤをキーに認証用データベースから認証結果を取得し、その判定結果を制御回路、外部Ｉ／Ｏ制御回路を介してＬＡＮにて制御シーケンサ（ＳＱＣ）２に伝達するようにする。
この制御シーケンサ２により操作盤Ｃの操作可能範囲を決定し、操作盤Ｃの操作権限を選択して、該付与操作権限範囲内での操作を可能とし、これにより運転員はスイッチ、コントロールレバーにてモータＭの運転、停止、バルブＶの開閉操作、スイッチＳのオンオフなどの必要なキー操作Ｃ２を、計測計やモニターＣ１等を目認しながら行うことができる。
また、その操作履歴を記録し、これにより誰が、いつ、どのような操作を行ったかを後刻検査することができる。 In this authentication determination circuit, an authentication result is acquired from the authentication database using the tag ID and the position ID as keys, and the determination result is transmitted to the control sequencer (SQC) 2 via the control circuit and the external I / O control circuit via the LAN. To communicate.
The control sequencer 2 determines the operable range of the operation panel C, selects the operation authority of the operation panel C, and enables the operation within the assigned operation authority range, thereby allowing the operator to switch and control lever. Thus, necessary key operations C2 such as operation and stop of the motor M, opening / closing operation of the valve V, and on / off of the switch S can be performed while observing the measuring instrument, the monitor C1, and the like.
In addition, the operation history is recorded, so that it is possible to inspect later who performed what operation.

また、図２に示す実施例は、事業所内に複数の設備が有する場合、中央監視センター（又は中央監視操作室）内に、設備毎の操作盤を隣接配設し、また現場事務所等内には各現場毎に現場操作盤を配設したものである。
この場合、中央監視センターの設備毎の各操作盤には赤外線発光器（赤外線発光ＬＥＤ）３を配備し、この各赤外線発光器（赤外線発光ＬＥＤ）３を認証コントローラＣＴＬとＬＡＮにて接続し、かつ各設備毎の各操作盤は制御シーケンサＳＱＣとＬＡＮにて接続されている。
また、現場事務所内の複数の現場操作盤には赤外線発光器（赤外線発光ＬＥＤ）３を配備し、この各赤外線発光器（赤外線発光ＬＥＤ）３を認証コントローラＣＴＬと接続し、この認証コントローラＣＴＬと制御シーケンサＳＱＣとをＬＡＮにて接続し、かつ制御シーケンサＳＱＣと現場操作盤とを、補助継電器盤４を介して接続されている。 Further, in the embodiment shown in FIG. 2, when there are a plurality of facilities in the office, an operation panel for each facility is disposed adjacent to the central monitoring center (or the central monitoring operation room), and in the field office or the like. Has a field operation panel for each site.
In this case, an infrared light emitting device (infrared light emitting LED) 3 is provided on each operation panel of each facility of the central monitoring center, and each infrared light emitting device (infrared light emitting LED) 3 is connected to the authentication controller CTL via a LAN. And each operation panel for each equipment is connected to the control sequencer SQC by LAN.
In addition, an infrared light emitter (infrared light emitting LED) 3 is provided in a plurality of field operation panels in the field office, and each infrared light emitter (infrared light emitting LED) 3 is connected to an authentication controller CTL. The control sequencer SQC is connected via a LAN, and the control sequencer SQC and the local operation panel are connected via the auxiliary relay panel 4.

この場合、運転員Ｍ１と運転員Ｍ２とが正規のタグを所持し、指定された操作盤宅前に着座し、操作盤を付与操作権限範囲内で操作を可能であるが、正規のタグを所持していない運転員Ｍ３は、操作権限を付与されないので操作盤Ｃを操作することができない。
このようにして複数台の操作盤が配置され、かつ複数の運転員にて同時に操作する場合においても、不正な操作、誤操作を防止することができる。 In this case, the operator M1 and the operator M2 have a regular tag, sit in front of the designated operation panel, and can operate the operation panel within the scope of the operation authority granted. The operator M3 not possessed cannot operate the operation panel C because the operation authority is not given.
In this way, even when a plurality of operation panels are arranged and operated by a plurality of operators at the same time, unauthorized operations and erroneous operations can be prevented.

以上、本発明のプラント設備における操作認証システムについて、実施例に基づいて説明したが、本発明は上記実施例に記載した構成に限定されるものではなく、その趣旨を逸脱しない範囲において適宜その構成を変更することができるものである。   As mentioned above, although the operation authentication system in the plant equipment of this invention was demonstrated based on the Example, this invention is not limited to the structure described in the said Example, The structure suitably in the range which does not deviate from the meaning. Can be changed.
