As you can see, alarm management focuses not only on the introduction and configuration of high-performance alarm systems and temporary alarm rationalization activities, but also on how to manage and maintain the alarm system. . The basic idea is to convey significant information to the operator in an easy-to-understand manner and rationalize alarms.
　伝送方式の異なる情報ネットワークと制御ネットワークを備える鉄鋼プラントが知られている。製造プロセスを管理する計算機のアラームは、情報ネットワークに出力される。計算機の設定情報に基づいて機器を制御するコントローラのアラームは、制御ネットワークに出力される。フォーマットの異なるこれらのアラームは別々に収集される。オペレータは、工場内に設置されたディスプレイに表示されるアラームリストを見ることで、システムが正常に稼働しているか否かを知ることができる。 Steel plants with information networks and control networks with different transmission methods are known. The alarm of the computer that manages the manufacturing process is output to the information network. The alarm of the controller that controls the device based on the setting information of the computer is output to the control network. These alarms with different formats are collected separately. The operator can know whether or not the system is operating normally by looking at the alarm list displayed on the display installed in the factory.
　これらのアラームの中には、センサの異常を示すアラームや、システムの何らかの異常を示すアラーム、コイル位置情報のずれを示すアラームや、デバッグ文まで多種多様である。そのため、アラーム仕様書を基に実装されるアラームメッセージは１工程で数百にも達し、アラームの実装に膨大な時間を要する。また、短時間でアラームが大量に発生し、アラームの解析にも時間を要する。日本特開平７－２００４７８号公報では、アラームの作成を共通フォーマットで自動生成する方法について述べられている。 Among these alarms, there are various types of alarms, such as an alarm indicating a sensor abnormality, an alarm indicating any abnormality of the system, an alarm indicating a deviation in coil position information, and a debug sentence. For this reason, the number of alarm messages to be implemented based on the alarm specifications reaches several hundred in one process, and it takes an enormous amount of time to implement the alarm. In addition, a large number of alarms occur in a short time, and it takes time to analyze the alarms. Japanese Patent Application Laid-Open No. 7-200478 describes a method for automatically generating alarms in a common format.
日本特開平７－２００４７８号公報Japanese Laid-Open Patent Publication No. 7-200478
　特許文献１に開示された装置は、計算機のアラーム情報の作成処理を自動化し、作成時間の短縮が図れるようにしているが、発生後のアラームに対する管理は実施していない。また、計算機のアラーム情報のみを収集しており、制御ネットワークのコントローラが出力するアラーム情報は別管理となっている。アラームマネジメントを実現しようとする場合に、収集されたアラーム情報のフォーマットが異なっていれば、アラームを蓄積・検索・統計する際に煩雑な処理が必要になる。例えば、プラント全体について同時期に発生したアラームを一覧表示させる場合に、アラームが複数箇所に別々の形式で蓄積されていたのでは、データ処理が煩雑になる。そのため、アラームマネジメントを実現するためには、プラント中の異なる複数のネットワーク上に異なる形式で出力されるアラーム情報を共通の形式でまとめて蓄積できることが望ましい。 The device disclosed in Patent Document 1 automates the creation process of alarm information of a computer so as to shorten the creation time, but does not manage the alarm after the occurrence. Moreover, only alarm information of the computer is collected, and alarm information output from the controller of the control network is managed separately. When the alarm management is to be realized, if the collected alarm information has a different format, complicated processing is required when accumulating, searching, and statistics of the alarm. For example, when a list of alarms generated at the same time for the entire plant is displayed, if the alarms are stored in a plurality of locations in different formats, data processing becomes complicated. Therefore, in order to realize alarm management, it is desirable that alarm information output in different formats on a plurality of different networks in the plant can be stored together in a common format.

The controller 51 and the controller 52 are connected to a plurality of devices. Specifically, for example, the controller 51 is connected to the driving device and electric motor 71 and the sensor 81. Similarly, the controller 52 is connected to the driving device and electric motor 72 and the sensor 82. The driving device and the electric motors 71 and 72 are devices for driving, for example, a roller provided in the rough rolling mill 101 in FIG. 2 and a water injection device provided in a run-out table (ROT) 104. The sensors 81 and 82 are, for example, the stock sensors 110 to 117 in FIG. 2 and temperature sensors (not shown) provided on the exit side of the nth finishing rolling mill 103.
（圧延ライン）
　図２は、鉄鋼プラント１が備える圧延ラインを示す概念図である。図２の圧延ラインは、熱間圧延ラインである。なお、圧延ラインは、厚板圧延ライン、冷間圧延ライン、線材圧延ライン、条鋼圧延ラインであってもよい。 (Rolling line)
FIG. 2 is a conceptual diagram showing a rolling line provided in the steel plant 1. The rolling line in FIG. 2 is a hot rolling line. The rolling line may be a thick plate rolling line, a cold rolling line, a wire rod rolling line, or a bar rolling line.
　圧延材は、圧延ラインの搬送テーブル１０７上を加熱炉１００から巻取機１０５まで搬送される過程で加熱され圧延され冷却される。図２の圧延ラインには、上流から順に、加熱炉１００、粗圧延機１０１、ｎ台の仕上圧延機、ＲＯＴ１０４、巻取機１０５、コイルコンベア１０６が配置される。図２には、ｎ台の仕上圧延機のうち第１仕上圧延機１０２と第ｎ仕上圧延機１０３が表わされている。 The rolled material is heated, rolled and cooled in the process of being conveyed from the heating furnace 100 to the winder 105 on the conveying table 107 of the rolling line. In the rolling line of FIG. 2, a heating furnace 100, a rough rolling mill 101, n finishing rolling mills, an ROT 104, a winder 105, and a coil conveyor 106 are arranged in this order from the upstream.

It is wound up. The rolled material (coil) wound up is conveyed to a downstream process by the coil conveyor 106 after being bundled or weighed.
（情報ネットワークと制御ネットワーク）
　図１の情報ネットワーク２は、操業及び製品製造に関するネットワークであり、ネットワークに接続する装置間でメッセージを送受信可能なネットワークである。 (Information network and control network)
An information network 2 in FIG. 1 is a network related to operations and product manufacturing, and is a network capable of transmitting and receiving messages between devices connected to the network.
　図１の制御ネットワーク３は、高信頼性とリアルタイム性を実現するプラント制御用ネットワークである。具体的には、制御ネットワーク３は、コモンメモリ方式によるスキャン伝送（周期的な同報伝送）で制御データの同時性を確保可能なネットワークである。制御ネットワーク３を実現する伝送技術の一例として、ＴＣｎｅｔ（ＩＥＣ（Ｉｎｔｅｒｎａｔｉｏｎａｌ　Ｅｌｅｃｔｒｏｔｅｃｈｎｉｃａｌ　Ｃｏｍｍｉｓｓｉｏｎ）規格“ＩＥＣ ６１７８４－１／ＩＥＣ ６１１５８”）が挙げられる。 1 is a plant control network that achieves high reliability and real-time performance. Specifically, the control network 3 is a network that can ensure the simultaneity of control data by scan transmission (periodic broadcast transmission) using a common memory system. As an example of a transmission technology that realizes the control network 3, TCnet (IEC (International Electrotechnical Commission) standard “IEC ４－ 617841 / IEC 61158”) can be cited.
　図１の制御ネットワーク３は、複数のノード（ノードＡ３１～ノードＤ３４）を備える。ノードはステーションとも称される。ノードＡ３１は計算機４を、ノードＢ３２はコントローラ５１を、ノードＣ３３はコントローラ５２を、ノードＤ３４は鉄鋼プラントアラームマネジメント装置６を備える。 1 includes a plurality of nodes (node A31 to node D34). Nodes are also referred to as stations. The node A31 includes the computer 4, the node B32 includes the controller 51, the node C33 includes the controller 52, and the node D34 includes the steel plant alarm management device 6.
　図３は、制御ネットワーク３におけるスキャン伝送について説明するための図である。図３に示すように、複数のノードＡ３１～ノードＤ３４は、それぞれ同一構成のコモンメモリ３１０～３４０を有する。各コモンメモリには、計算機４による設定情報が書き込まれる記憶領域、コントローラ５１の出力データ（駆動装置及び電動機７１およびセンサ８１の出力データを含む）が書き込まれる記憶領域、コントローラ５２の出力データ（駆動装置及び電動機７２およびセンサ８２の出力データを含む）が書き込まれる記憶領域が重複しないように割り当てられている。 FIG. 3 is a diagram for explaining scan transmission in the control network 3. As shown in FIG. 3, the plurality of nodes A31 to D34 have common memories 310 to 340 having the same configuration. In each common memory, a storage area in which setting information by the computer 4 is written, a storage area in which output data of the controller 51 (including output data of the driving device and the motor 71 and the sensor 81) is written, and output data (driving) of the controller 52 The storage areas in which the device and the output data of the motor 72 and the sensor 82 are written) are assigned so as not to overlap.
　例えば、各コモンメモリには、計算機４が出力する設定情報（圧延材（スラブ、コイル）の仕様）を記憶する記憶領域、コントローラ５１、５２の障害内容毎に定めたアラームシンボルの状態を記憶する記憶領域、駆動装置及び電動機７１、７２の障害内容毎に定めたアラームシンボルの状態を記憶する記憶領域、センサ８１、８２（例えば、在荷センサ）が出力する圧延材の位置を示す在荷シンボルの状態を記憶する記憶領域が重複しないように割り当てられている。なお、アラームシンボルの状態と在荷シンボルの状態は、シンボル名に対応するメモリ空間に、ＯＮ状態またはＯＦＦ状態を示すビット信号で記憶される。 For example, each common memory stores a storage area for storing setting information output from the computer 4 (specifications of rolled material (slab, coil)), and alarm symbol states determined for each failure content of the controllers 51 and 52. A storage area for storing the state of an alarm symbol determined for each failure content of the storage area, the drive device and the motors 71 and 72, and a stock symbol indicating the position of the rolled material output by the sensors 81 and 82 (for example, a stock sensor) The storage areas for storing the states are assigned so as not to overlap. The state of the alarm symbol and the state of the in-stock symbol are stored as bit signals indicating the ON state or the OFF state in the memory space corresponding to the symbol name.
　各ノードは、自ノードが管理するコモンメモリ上のデータを、他のすべてのノードに周期的に同報伝送する同報伝送機能を有する。例えば、ノードＢ３２は、コモンメモリ３２０上のコントローラ５１の出力データが書き込まれる記憶領域にあるデータを、他のすべてのノードに周期的に同報伝送して、各コモンメモリ上のデータを同期する。制御ネットワーク３は、数ｍｓｅｃ周期でスキャン伝送を実施可能である。 Each node has a broadcast transmission function that periodically broadcasts data on the common memory managed by the node to all other nodes. For example, the node B32 periodically broadcasts the data in the storage area where the output data of the controller 51 on the common memory 320 is written to all other nodes, and synchronizes the data on each common memory. . The control network 3 can perform scan transmission with a period of several msec.
　図１に戻り説明を続ける。計算機４は、情報ネットワーク２に接続すると共に、ノードＡ３１を介して制御ネットワーク３に接続する。コントローラ５１は、ノードＢ３２を介して制御ネットワーク３に接続する。コントローラ５２は、ノードＣ３３を介して制御ネットワーク３に接続する。鉄鋼プラントアラームマネジメント装置６は、情報ネットワーク２に接続すると共に、ノードＤ３４を介して制御ネットワーク３に接続する。 Referring back to FIG. The computer 4 is connected to the information network 2 and is connected to the control network 3 via the node A31. The controller 51 is connected to the control network 3 via the node B32. The controller 52 is connected to the control network 3 via the node C33. The steel plant alarm management device 6 is connected to the information network 2 and is connected to the control network 3 via the node D34.
（計算機）
　計算機４は、鉄鋼プラント１における製造プロセスを総合的に管理するプロセスコンピュータであり、例えば、圧延現象を模した物理モデルを用いてプラント制御のための設定計算を行う。設定計算の結果（設定情報）は、制御ネットワーク３を介して、コントローラ５１、５２に送られる。また、計算機４は、異常が発生した場合に、発生時刻、重要度、発生設備名、表示メッセージを含む計算機アラーム情報を、情報ネットワーク２を介して鉄鋼プラントアラームマネジメント装置６に送信する。 (calculator)
The computer 4 is a process computer that comprehensively manages the manufacturing process in the steel plant 1. For example, the computer 4 performs setting calculation for plant control using a physical model simulating a rolling phenomenon. The setting calculation result (setting information) is sent to the controllers 51 and 52 via the control network 3. In addition, when an abnormality occurs, the computer 4 transmits computer alarm information including the time of occurrence, the importance, the name of the generated facility, and a display message to the steel plant alarm management device 6 via the information network 2.
（コントローラ）
　コントローラ５１、５２は、計算機４の設定情報を用いて各機器を制御する。また、コントローラ５１、５２は、異常が発生した場合に、ノードＢ３２のコモンメモリ上のアラームシンボルの状態をＯＮ状態に変更する。 (controller)
The controllers 51 and 52 control each device using the setting information of the computer 4. In addition, when an abnormality occurs, the controllers 51 and 52 change the state of the alarm symbol on the common memory of the node B 32 to the ON state.
（鉄鋼プラントアラームマネジメント装置のハードウエア）
　次に、鉄鋼プラントアラームマネジメント装置６の構成について説明する。鉄鋼プラントアラームマネジメント装置６は、Ｃｅｎｔｒａｌ　Ｐｒｏｃｅｓｓｉｎｇ　Ｕｎｉｔ（ＣＰＵ）、Ｒｅａｄ　Ｏｎｌｙ　Ｍｅｍｏｒｙ（ＲＯＭ）、Ｒａｎｄｏｍ　Ａｃｃｅｓｓ　Ｍｅｍｏｒｙ（ＲＡＭ）、ハードディスク及び通信インタフェース等のハードウエア資源を備えている。ＣＰＵは、与えられた命令（命令の集合であるプログラムを含む）を実行して情報の演算又は加工を行う装置である。ＲＯＭは、データ又はプログラムを不揮発的に格納する読み出し専用メモリである。ＲＡＭは、データ又はプログラムを揮発的すなわち一時的に格納するための読み書き可能なメモリである。これらのＲＯＭ及びＲＡＭは、ＣＰＵから直接にアクセス可能な主記憶装置である。ハードディスク（ハードディスクドライブ）は、ＣＰＵから直接にアクセス可能ではない補助記憶装置である。ハードディスクは、データ又はプログラムを不揮発的に格納することができる。通信インタフェースは、鉄鋼プラントアラームマネジメント装置６が外部との通信を行う場合に必要なハードウエアである。これらの、ＣＰＵ、ＲＯＭ、ＲＡＭ、ハードディスク及び通信インタフェースは、バス又は接続ケーブル等により相互に情報のやり取りが可能なように接続されている。 (Steel plant alarm management equipment hardware)
Next, the configuration of the steel plant alarm management device 6 will be described. The steel plant alarm management device 6 includes hardware resources such as a central processing unit (CPU), a read only memory (ROM), a random access memory (RAM), a hard disk, and a communication interface. The CPU is a device that executes a given instruction (including a program that is a set of instructions) to perform calculation or processing of information. The ROM is a read-only memory that stores data or programs in a nonvolatile manner. The RAM is a readable / writable memory for storing data or programs in a volatile manner, that is, temporarily. These ROM and RAM are main storage devices that are directly accessible from the CPU. A hard disk (hard disk drive) is an auxiliary storage device that is not directly accessible from the CPU. The hard disk can store data or programs in a nonvolatile manner. The communication interface is hardware necessary when the steel plant alarm management device 6 communicates with the outside. These CPU, ROM, RAM, hard disk and communication interface are connected to each other via a bus or a connection cable so that information can be exchanged.
　鉄鋼プラントアラームマネジメント装置６を構成するコンピュータのＲＯＭには、以上のように構成されたコンピュータを鉄鋼プラントアラームマネジメント装置６として動作させるためのプログラムが予め格納されている。そして、ＣＰＵは、まず、ＲＯＭからプログラムを読み出してＲＡＭに実行可能な形式でプログラムを格納する。そして、ＣＰＵは、このＲＡＭに格納されたプログラムを読み出しながら実行する。 A program for operating the computer configured as described above as the steel plant alarm management device 6 is stored in advance in the ROM of the computer constituting the steel plant alarm management device 6. The CPU first reads the program from the ROM and stores the program in a format that can be executed in the RAM. The CPU executes the program stored in the RAM while reading it.
　このようにして、ソフトウエアたるプログラムがコンピュータに読み込まれることにより、ソフトウエアとハードウエア資源とが協働した具体的手段によって、情報の演算又は加工を実現することで、図１に示す各部の機能を備えた鉄鋼プラントアラームマネジメント装置６が構築される。 In this way, when the software program is read into the computer, the calculation or processing of the information is realized by specific means in which the software and hardware resources cooperate with each other as shown in FIG.

　シンボル監視部６１は、ノードＤ３４が備えるコモンメモリ３４０上のシンボル（アラームシンボル、在荷シンボル）の状態を、上述したスキャン伝送と同じ伝送周期で監視する。シンボル監視部６１は、シンボルのＯＮ状態を検出すると、シンボル名と検出時刻（発生時刻に相当）を収集部６２に送る。 The symbol monitoring unit 61 monitors the state of symbols (alarm symbols and in-stock symbols) on the common memory 340 included in the node D34 at the same transmission cycle as that of the scan transmission described above. When the symbol monitoring unit 61 detects the ON state of the symbol, the symbol monitoring unit 61 sends the symbol name and the detection time (corresponding to the generation time) to the collection unit 62.
　収集部６２は、アラーム定義テーブルを有する。アラーム定義テーブルは、アラームシンボル名と重要度と発生設備名と表示メッセージとの関係を定めたテーブルである。なお、蓄積部６３がアラーム定義テーブルを備え、収集部６２がこれを取得しても良い。収集部６２は、ＯＮ状態が検出されたアラームシンボル（ＯＮ状態アラームシンボル）について、そのアラームシンボル名に対応する重要度と発生設備名と表示メッセージとをアラーム定義テーブルから取得する。収集部６２は、ＯＮ状態アラームシンボルが検出された時刻である発生時刻と、取得した重要度および発生設備名と表示メッセージとを含む情報をコントローラアラーム情報として収集する。コントローラアラーム情報は、他の情報（例えば、シンボル名）を含んでも良い。 The collection unit 62 has an alarm definition table. The alarm definition table is a table that defines the relationship between the alarm symbol name, the importance level, the name of the generating facility, and the display message. The storage unit 63 may include an alarm definition table, and the collection unit 62 may acquire this. For the alarm symbol (ON state alarm symbol) in which the ON state is detected, the collection unit 62 acquires the importance level, the generation facility name, and the display message corresponding to the alarm symbol name from the alarm definition table.

The alarm factor correspondence definition table is a table that defines the relationship between symbol names, occurrence factors, countermeasures, and alarms (symbol names) that have a strong relationship. FIG. 5 is a diagram illustrating an example of information stored in the alarm factor correspondence definition table. The alarm factor correspondence definition table is a table that defines the relationship between a symbol name, one or more occurrence factors, a strongly related alarm, and a response method. The alarm information storage table in FIG. 4 and the alarm factor correspondence definition table in FIG. 5 have symbol names as common fields. Therefore, it is possible to associate an occurrence factor and a response method with the alarm information searched by the operator.
　好ましくは、収集部６２は、在荷情報定義テーブルを有する。在荷情報定義テーブルは、設備名と在荷シンボル名とコイル番号（圧延材番号）との関係を定めたテーブルである。なお、蓄積部６３が在荷情報定義テーブルを備え、収集部６２がこれを取得しても良い。設備入側の在荷シンボルは、設備の入側に配置された在荷センサに、設備出側の在荷シンボルは、設備の出側に配置された在荷センサに対応する。在荷シンボルの状態は、各設備の入側と出側に配置された在荷センサが圧延材を検出するとＯＮ状態に変更される。 Preferably, the collection unit 62 has a stock information definition table. The inventory information definition table is a table that defines the relationship among equipment names, inventory symbol names, and coil numbers (rolled material numbers). The storage unit 63 may include a stock information definition table, and the collection unit 62 may acquire this. The stock symbol on the equipment entry side corresponds to the stock sensor arranged on the entrance side of the equipment, and the stock symbol on the equipment exit side corresponds to the stock sensor arranged on the exit side of the equipment. The state of the stock symbol is changed to the ON state when the stock sensors arranged on the entry side and the exit side of each facility detect the rolled material.
　図６は、在荷情報定義テーブルの一例を示す図である。在荷情報定義テーブルは、少なくとも設備名と在荷シンボル名（スタートシンボルとエンドシンボル）とコイル番号とをフィールドとして含む。設備Ｆ入側の在荷シンボル（スタートシンボル）ＲＭ＿ＦＯＮの状態は、在荷センサ１１０が圧延材を検出した時にＯＮ状態となる。設備ＲＭ入側の在荷シンボル（スタートシンボル）ＲＭ＿ＲＭＯＮの状態は、在荷センサ１１１が圧延材を検出した時にＯＮ状態となる。設備Ｆ１入側の在荷シンボル（スタートシンボル）ＦＭＥ＿Ｆ１ＯＮの状態は、在荷センサ１１２が圧延材を検出した時にＯＮ状態となる。なお、図６のように、前設備のエンドシンボルを次設備のスタートシンボルと同一シンボルとすることで、設備出側の在荷センサを省略することができる。 FIG. 6 is a diagram showing an example of a stock information definition table. The inventory information definition table includes at least an equipment name, inventory symbol name (start symbol and end symbol), and coil number as fields. The state of the in-stock symbol (start symbol) RM_FON on the equipment F entry side is ON when the in-stock sensor 110 detects the rolled material. The state of the in-stock symbol (start symbol) RM_RMON on the equipment RM entry side is ON when the in-stock sensor 111 detects the rolled material. The state of the in-stock symbol (start symbol) FME_F1ON on the equipment F1 entry side is ON when the in-stock sensor 112 detects the rolled material. As shown in FIG. 6, by setting the end symbol of the previous equipment to the same symbol as the start symbol of the next equipment, the in-stock sensor on the equipment delivery side can be omitted.
　収集部６２は、ＯＮ状態が検出された在荷シンボル（ＯＮ状態在荷シンボル）について、在荷情報定義テーブルに基づいて、設備名と、ＯＮ状態在荷シンボルが検出された検出時刻と、コイル番号とを関連付けて在荷情報として収集する。コイル番号は、計算機４が出力する設定情報に含まれ、コモンメモリから取得可能である。 For the in-stock symbol in which the ON state is detected (ON-state in-stock symbol), the collection unit 62, based on the in-stock information definition table, the detection time when the on-state in-stock symbol is detected, the coil Collect as inventory information in association with the number. The coil number is included in the setting information output by the computer 4 and can be acquired from the common memory.
　蓄積部６３は、収集部６２が収集した在荷情報を、データベースの在荷情報格納テーブルに所定の期間格納する。在荷情報格納テーブルは、少なくとも設備名と、スタートシンボルの検出時刻と、エンドシンボルの検出時刻と、コイル番号とがフィールドとして定められたテーブルである。スタートシンボルの検出時刻からエンドシンボルの検出時刻までの期間からコイルが設備に滞在した在荷期間を算出できる。在荷期間を用いることで、アラーム情報格納テーブルから在荷期間中に発生したアラームの件数を集計可能である。 The accumulation unit 63 stores the inventory information collected by the collection unit 62 in the inventory information storage table of the database for a predetermined period. The inventory information storage table is a table in which at least an equipment name, a start symbol detection time, an end symbol detection time, and a coil number are defined as fields. From the period from the start symbol detection time to the end symbol detection time, the inventory period during which the coil stays in the facility can be calculated. By using the inventory period, the number of alarms generated during the inventory period can be tabulated from the alarm information storage table.
　アラーム検索部６４は、オペレータが入力した検索条件（キーワード、カテゴリ、重要度）に基づいて、蓄積部６３のデータベースに格納されたアラーム情報を検索する。アラーム検索部６４は、画面表示部６８を介してオペレータが入力した検索条件を取得し、蓄積部６３のデータベースから検索条件に応じた検索結果を取得する。検索結果は、画面表示部６８に送られる。なお、上述したように図４のアラーム情報格納テーブルと図５のアラーム要因対応定義テーブルは、共通のフィールドとしてシンボル名を有する。そのため、検索結果にはアラーム情報に発生要因および対応方法を関連付けた情報が含まれる。 The alarm search unit 64 searches the alarm information stored in the database of the storage unit 63 based on the search conditions (keyword, category, importance) input by the operator. The alarm search unit 64 acquires search conditions input by the operator via the screen display unit 68 and acquires search results corresponding to the search conditions from the database of the storage unit 63. The search result is sent to the screen display unit 68. As described above, the alarm information storage table in FIG. 4 and the alarm factor correspondence definition table in FIG. 5 have symbol names as common fields. For this reason, the search result includes information in which the cause and the response method are associated with the alarm information.
　アラーム登録部６５は、蓄積部６３のアラーム要因対応定義テーブルにアラームのシンボル名、発生要因、関係の強いアラーム、対応方法を登録する。アラーム登録部６５は、画面表示部６８を介してオペレータが入力した登録情報を取得し、蓄積部６３のアラーム要因対応定義テーブルに格納する。 The alarm registration unit 65 registers an alarm symbol name, an occurrence factor, a strongly related alarm, and a response method in the alarm factor correspondence definition table of the storage unit 63.

The alarm statistics unit 66 obtains the coil stock period corresponding to the equipment name and coil number from the stock information storage table, and searches the alarm information storage table using the stock period to generate the stock period. It is possible to count the number of alarm occurrences for each facility and each coil. Thereby, the statistical information which linked | related the coil number and alarm information can be provided.
　アラーム抑制部６７は、イベント条件、発生時間、発生回数などを指定することでアラームの表示／非表示を切り替える。アラーム抑制部６７は、手動または自動でアラームの表示を切り替える。手動アラーム表示切り替えでは、オペレータは、オペレータ操作端末７を介して、アラーム毎に表示／非表示の切り替えを行うことができる。これにより、大量のアラームから、重要なアラームを絞り込んで表示させることができる。 The alarm suppression unit 67 switches between displaying and hiding alarms by designating event conditions, occurrence times, occurrence counts, and the like. The alarm suppression unit 67 switches the display of alarms manually or automatically. In manual alarm display switching, the operator can switch display / non-display for each alarm via the operator operation terminal 7. Thereby, it is possible to narrow down and display important alarms from a large number of alarms.

The alarm suppression screen is a screen for switching display / non-display of an alarm by designating an event condition, an occurrence time, an occurrence count, and the like.
　次に、図７と図８を用いて、コントローラアラーム情報と計算機アラーム情報がデータベース上の共通テーブル（アラーム情報格納テーブル）に格納されるまでの処理について説明する。 Next, processing until controller alarm information and computer alarm information are stored in a common table (alarm information storage table) on the database will be described with reference to FIGS.
（フローチャート１）
　図７は、コントローラ５１、５２が制御ネットワーク３に出力したアラームがデータベースに格納されるまでの処理の流れを表すフローチャートである。上述したようにシンボル監視部６１は、コモンメモリ３４０の各シンボルの状態を示すビット信号を周期的に監視している。 (Flowchart 1)
FIG. 7 is a flowchart showing the flow of processing until the alarm output from the controllers 51 and 52 to the control network 3 is stored in the database. As described above, the symbol monitoring unit 61 periodically monitors the bit signal indicating the state of each symbol in the common memory 340.
　シンボル監視部６１は、アラームシンボルのビット信号がＯＮ状態になったことを検出すると、そのシンボル名と検出時刻（発生時刻に相当）を収集部６２に送る（ステップＳ１００）。 When the symbol monitoring unit 61 detects that the bit signal of the alarm symbol is in the ON state, the symbol monitoring unit 61 sends the symbol name and detection time (corresponding to the generation time) to the collection unit 62 (step S100).
　収集部６２は、シンボル名が上述したアラーム定義テーブルに登録されたシンボル名であるか否かを判定する（ステップＳ１０２）。 The collection unit 62 determines whether or not the symbol name is a symbol name registered in the above-described alarm definition table (step S102).
　シンボル名がアラーム定義テーブルに登録されている場合、収集部６２は、アラーム定義テーブルからシンボル名に対応する重要度、発生設備名、表示メッセージを取得する。収集部６２は、シンボル名、発生時刻、重要度、発生設備名、表示メッセージをコントローラアラーム情報として収集する。収集部６２は、コントローラアラーム情報を蓄積部６３に送る。 When the symbol name is registered in the alarm definition table, the collection unit 62 acquires the importance level, the name of the generating facility, and the display message corresponding to the symbol name from the alarm definition table. The collection unit 62 collects the symbol name, generation time, importance, generation facility name, and display message as controller alarm information. The collection unit 62 sends the controller alarm information to the storage unit 63.
　蓄積部６３は、シンボル名、発生時刻、重要度、発生設備名、表示メッセージを項目として含む共通フォーマットに従いアラーム情報を抽出する（ステップＳ１０４）。蓄積部６３は、抽出したアラーム情報をデータベースに格納する（ステップＳ１０６）。具体的には、蓄積部６３は、上述した共通テーブル（アラーム情報格納テーブル）にアラーム情報を所定の期間格納する。 The storage unit 63 extracts alarm information in accordance with a common format including the symbol name, generation time, importance, generation facility name, and display message as items (step S104). The accumulation unit 63 stores the extracted alarm information in the database (step S106). Specifically, the storage unit 63 stores the alarm information in the common table (alarm information storage table) described above for a predetermined period.
（フローチャート２）
　図８は、計算機４が情報ネットワーク２に出力した計算機アラーム情報がデータベースに格納されるまでの処理の流れを表すフローチャートである。収集部６２は、計算機アラーム情報を受信する（ステップＳ２００）。収集部６２は、計算機アラーム情報を蓄積部６３に送る。蓄積部６３は、計算機アラーム情報からを上述の共通フォーマットに従いアラーム情報を抽出する（ステップＳ２０２）。蓄積部６３は、抽出したアラーム情報をデータベースに格納する（ステップＳ２０４）。具体的には、蓄積部６３は、上述した共通テーブル（アラーム情報格納テーブル）にアラーム情報を所定の期間格納する。 (Flowchart 2)
FIG. 8 is a flowchart showing the flow of processing until the computer alarm information output from the computer 4 to the information network 2 is stored in the database. The collection unit 62 receives computer alarm information (step S200). The collection unit 62 sends computer alarm information to the storage unit 63. The storage unit 63 extracts alarm information from the computer alarm information according to the common format described above (step S202). The accumulation unit 63 stores the extracted alarm information in the database (step S204). Specifically, the storage unit 63 stores the alarm information in the common table (alarm information storage table) described above for a predetermined period.
　図７、図８について説明したように、本システムは、コントローラアラーム情報および計算機アラーム情報から共通フォーマットに従いアラーム情報を抽出し、抽出したアラーム情報を共通テーブルに格納できる。プラント中の異なる複数のネットワーク上に異なる形式で出力されるアラーム情報を共通の形式でまとめて蓄積できることができ、アラームマネジメントのための好適なデータ蓄積が実現される。 As described with reference to FIGS. 7 and 8, this system can extract alarm information from controller alarm information and computer alarm information according to a common format, and store the extracted alarm information in a common table. Alarm information output in different formats on different networks in the plant can be stored together in a common format, and suitable data storage for alarm management is realized.
（フローチャート３）
　図９は、アラーム要因対応定義テーブルに登録情報を登録する処理の流れを表すフローチャートである。オペレータは、オペレータ操作端末７に表示された発生アラーム一覧から対象アラームを選択する（ステップＳ３００）。オペレータ操作端末７は、鉄鋼プラントアラームマネジメント装置６に問い合わせ、過去にアラーム要因対応定義テーブルに登録情報が登録されている場合には、アラーム要因対応定義テーブルから対象アラームのシンボル名に関連した登録情報を取得し、画面に表示する（ステップＳ３０２）。オペレータは、新たに登録情報を登録するか否かを選択する（ステップＳ３０４）。登録する場合には、アラーム登録画面が表示される（ステップＳ３０６）。オペレータは、アラーム登録画面に対象アラームの発生要因、関係の強いアラーム、対応方法を登録情報として入力する（ステップＳ３０８）。蓄積部６３は、登録情報をデータベースのアラーム要因対応定義テーブルに格納する（ステップＳ３１０）。 (Flowchart 3)
FIG. 9 is a flowchart showing the flow of processing for registering registration information in the alarm factor correspondence definition table. The operator selects a target alarm from the list of generated alarms displayed on the operator operation terminal 7 (step S300). The operator operation terminal 7 makes an inquiry to the steel plant alarm management device 6, and if registration information has been registered in the alarm factor correspondence definition table in the past, the registration information related to the symbol name of the target alarm from the alarm factor correspondence definition table. Is acquired and displayed on the screen (step S302). The operator selects whether or not to newly register registration information (step S304). When registering, an alarm registration screen is displayed (step S306). The operator inputs the cause of the target alarm, the closely related alarm, and the response method as registration information on the alarm registration screen (step S308). The storage unit 63 stores the registration information in the alarm factor correspondence definition table of the database (step S310).
　図９について説明したように、本システムは、過去に発生したアラームに関して、その発生要因、関係の強いアラーム、対応方法をアラーム要因対応定義テーブルに定義しておくことができる。また、上述したように図４のアラーム情報格納テーブルと図５のアラーム要因対応定義テーブルはアラームのシンボル名で関連付いている。そのため、本システによれば、将来、同一または関係の強いアラームが発生した場合に、アラーム情報およびアラーム情報に関連付いた発生要因や対応方法を、オペレータにガイダンスすることができる。 As described with reference to FIG. 9, the present system can define in the alarm factor correspondence definition table the cause of occurrence, a strongly related alarm, and the handling method for alarms that have occurred in the past. Further, as described above, the alarm information storage table in FIG. 4 and the alarm factor correspondence definition table in FIG. 5 are related by the symbol name of the alarm. Therefore, according to the present system, when the same or strongly related alarm is generated in the future, it is possible to provide guidance to the operator about the alarm information and the generation factor associated with the alarm information and the response method.
（フローチャート４）
　図１０は、自動アラーム抑制機能の処理の流れを表すフローチャートである。前提として、アラーム抑制画面において自動アラーム抑制が選択されているものとする。アラーム抑制部６７は、アラーム抑制画面においてアラーム毎に設定された表示フラグがＯＮであるか否かを判定する（ステップＳ４００）。アラーム抑制部６７は、予め定められた自動アラーム抑制条件に従って、アラームの表示／非常時を決定する。アラーム抑制条件として、例えば、アラームがｎ秒あたりｍ回以上発生していることか否か（ステップＳ４０２）、所定フラグがＯＮ／ＯＦＦしているか否か（ステップＳ４０４）を判定し、判定条件に応じて、表示／非表示の切り替えを行う（ステップＳ４０６）。 (Flowchart 4)
FIG. 10 is a flowchart showing the flow of processing of the automatic alarm suppression function. It is assumed that automatic alarm suppression is selected on the alarm suppression screen. The alarm suppression unit 67 determines whether or not the display flag set for each alarm on the alarm suppression screen is ON (step S400). The alarm suppression unit 67 determines alarm display / emergency according to a predetermined automatic alarm suppression condition. As an alarm suppression condition, for example, it is determined whether or not an alarm has occurred m times or more per n seconds (step S402), and whether or not a predetermined flag is ON / OFF (step S404). Accordingly, display / non-display is switched (step S406).
　以上説明したように、本システムによれば、制御ネットワーク上のコントローラが出力するアラーム、及び情報ネットワーク上の計算機が出力するアラームを収集し、発生時刻、重要度、発生設備名、表示メッセージなどの共通フォーマットでデータベースに蓄積することができる。すなわち、プラント中の異なる複数のネットワーク上に異なる形式で出力されるアラーム情報を共通の形式でまとめて蓄積できることができる。さらに、アラーム検索部６４、アラーム登録部６５、アラーム統計部６６、アラーム抑制部６７を備えることで、アラームマネジメントを行い、オペレータに対してわかりやすいアラームシステムを構築することができる。
　また、データベースに蓄積されたアラーム情報を検索し、当該アラームの発生要因や対応方法をオペレータと共有し、さらに、単位時間あたり、コイル毎、設備毎にアラーム発生件数を計算しアラーム統計結果を表示することで、一過性のアラームマネジメント活動でなく、アラームマネジメントのＰＤＣＡサイクルを行うことができる。アラーム発生要因や対応方法をオペレータに示すことで、アラーム発生時の迅速な対応が可能となり、鉄鋼プラントの安定稼働につなげることができる。 As described above, according to the present system, alarms output by the controller on the control network and alarms output by the computer on the information network are collected, and the occurrence time, importance, name of the generated facility, display message, etc. are collected. Can be stored in a database in a common format. In other words, alarm information output in different formats on a plurality of different networks in the plant can be stored together in a common format. Furthermore, by providing the alarm search unit 64, the alarm registration unit 65, the alarm statistics unit 66, and the alarm suppression unit 67, it is possible to perform alarm management and construct an alarm system that is easy for the operator to understand.
Search the alarm information stored in the database, share the cause and response method of the alarm with the operator, calculate the number of alarm occurrences per unit time, coil, and equipment and display the alarm statistics results By doing so, it is possible to perform a PDCA cycle of alarm management instead of a temporary alarm management activity. By showing the alarm generation factor and response method to the operator, it is possible to promptly respond to the alarm occurrence, which can lead to stable operation of the steel plant.
