Description
本発明は、ネットワークに接続されている各ノードの障害情報を処理する障害情報処理装置、障害情報処理方法および障害情報処理システムに関する。
The present invention relates to a failure information processing apparatus, a failure information processing method, and a failure information processing system for processing failure information of each node connected to a network.
従来、産業用ネットワークでは、障害発生時における迅速なトラブルシュートを実施するために、ネットワークを構成する各ノードに、障害の発生を検出する検出手段が備えられている。検出手段が障害の発生を検出した場合、検出手段が取得した障害情報は各ノードが備えている障害情報格納メモリにおいて、障害内容ごとに格納される。障害情報格納メモリが格納する障害情報は、例えば、各障害の発生の有無を示す情報と、各障害の発生原因を示す情報とを含む。
Conventionally, in an industrial network, in order to perform quick troubleshooting when a failure occurs, each node constituting the network is provided with detection means for detecting the occurrence of the failure. When the detection unit detects the occurrence of a failure, the failure information acquired by the detection unit is stored for each failure content in the failure information storage memory provided in each node. The failure information stored in the failure information storage memory includes, for example, information indicating whether each failure has occurred and information indicating the cause of each failure.
障害の発生を検出する検出手段は、常にノードの状態を監視し、障害が発生した瞬間の障害情報をリアルタイムに障害情報格納メモリへ格納している。これにより、産業用ネットワークでは、障害が発生した場合に、速やかにその障害の原因を特定することが可能となる。
Detecting means for detecting the occurrence of a fault always monitors the state of the node and stores fault information at the moment when the fault occurs in the fault information storage memory in real time. Thereby, in the industrial network, when a failure occurs, it becomes possible to quickly identify the cause of the failure.
従来の技術では、障害情報格納メモリに格納される障害情報は、常に最新の情報へ更新されることとなる。このため、発生から短時間で復旧するような障害については、障害情報格納メモリの障害情報を参照しても、発生したこと自体が把握できなくなるという問題が生じる。
In the conventional technology, the failure information stored in the failure information storage memory is always updated to the latest information. For this reason, there is a problem that a failure that can be recovered in a short time after occurrence cannot be grasped even if the failure information in the failure information storage memory is referred to.
また、他の従来技術としては、ネットワークの障害を分析するネットワーク監視装置を用いるものがある（例えば、特許文献１参照）。このネットワーク監視装置は、ネットワークの伝送路に接続される。ネットワーク監視装置は、各ノードが送受信している伝送フレームを受信し、その伝送フレームに発生したＣＲＣエラーを障害として検出する。しかし、ＣＲＣエラーは、送受信データの誤りを示すものであるため、その原因となるノードの電源断やネットワークケーブルの断線等までは特定できないことが問題となる。
Further, as another conventional technique, there is one using a network monitoring device that analyzes a network failure (see, for example, Patent Document 1). This network monitoring device is connected to a network transmission line. The network monitoring device receives a transmission frame transmitted / received by each node, and detects a CRC error occurring in the transmission frame as a failure. However, since the CRC error indicates an error in the transmission / reception data, it is problematic that it is impossible to identify the power failure of the node or the disconnection of the network cable that causes the error.
本発明は、上記に鑑みてなされたものであって、各ノードからの障害情報を蓄積することで、過去に発生した障害の分析やネットワークシステムの状況把握を可能とする障害情報処理装置、障害情報処理方法および障害情報処理システムを得ることを目的とする。
The present invention has been made in view of the above, and has accumulated failure information from each node, thereby enabling analysis of a failure that has occurred in the past and grasping the status of a network system, failure, and the like. An object is to obtain an information processing method and a fault information processing system.
上述した課題を解決し、目的を達成するために、本発明は、ネットワークに接続されている各ノードが備える障害情報格納メモリから、ノードで発生した障害に関する障害情報を一定周期ごとに取得する障害情報取得部と、前記障害情報取得部が取得した前記障害情報を演算処理する障害情報演算部と、を有し、前記障害情報演算部は、前記ノードごとについて、障害の内容別の障害発生回数および障害発生率の少なくとも一方を、障害情報統計データとして記録することを特徴とする。
In order to solve the above-described problems and achieve the object, the present invention provides a fault that acquires fault information about a fault that has occurred in a node at regular intervals from a fault information storage memory provided in each node connected to the network. An information acquisition unit; and a failure information calculation unit that calculates the failure information acquired by the failure information acquisition unit, wherein the failure information calculation unit includes a failure occurrence count for each node for each failure content. And at least one of the failure occurrence rates is recorded as failure information statistical data.
本発明では、産業用ネットワークにて発生した障害の分析に必要となる障害情報を、各ノードの障害情報格納メモリから一定周期ごとに収集し、蓄積する。障害情報処理装置は、蓄積された情報を参照することで、産業用ネットワークにて過去に発生した障害の傾向について分析することができる。また、長期間に渡り障害情報を蓄積可能とすることで、ネットワークシステム上において通信が不安定な箇所を把握することができる。
In the present invention, fault information necessary for analyzing a fault that has occurred in an industrial network is collected and stored at regular intervals from the fault information storage memory of each node. The failure information processing apparatus can analyze the tendency of failures that occurred in the past in the industrial network by referring to the accumulated information. In addition, since failure information can be accumulated over a long period of time, it is possible to grasp a place where communication is unstable on the network system.

The failure information calculation unit 5 records data obtained by the calculation process in the internal memory 6 as failure information statistical data 7. The failure information calculation unit 5 records the failure occurrence frequency and failure occurrence rate for each node as failure information statistical data 7 for each node.

The internal memory 6 holds failure information statistical data 7 written from the failure information calculation unit 5. The display device 8 reads out the failure information statistical data 7 recorded in the internal memory 6 and performs a graphic display of the failure information statistical data 7.
図２は、障害情報処理装置における障害情報の処理の手順を示すフローチャートである。障害情報処理装置３は、障害情報取得部４にて一定周期ごとに全ノード１０から障害情報２を取得する際に、ここで説明する処理を実施する。
FIG. 2 is a flowchart showing a procedure of fault information processing in the fault information processing apparatus. The failure information processing apparatus 3 performs the process described here when the failure information acquisition unit 4 acquires the failure information 2 from all the nodes 10 at regular intervals.
障害情報取得部４が障害情報２を取得する（障害情報取得工程）と、障害情報演算部５は、障害情報統計データ７内の障害情報確認回数を１加算する（ステップＳ１１）。障害情報取得部４は、取得した障害情報２を１件ずつ解析し（ステップＳ１２）、各ノード１０における各障害の発生の有無を確認する（ステップＳ１３）。
When the failure information acquisition unit 4 acquires the failure information 2 (failure information acquisition step), the failure information calculation unit 5 adds 1 to the number of times of failure information confirmation in the failure information statistical data 7 (step S11). The failure information acquisition unit 4 analyzes the acquired failure information 2 one by one (step S12), and confirms whether or not each failure has occurred in each node 10 (step S13).
障害の発生が確認された場合（ステップＳ１３、Ｙｅｓ）、障害情報演算部５は、障害が発生したノード１０および当該障害の内容について障害情報統計データ７が保持する障害発生回数を１加算する（ステップＳ１４）。次に、障害情報演算部５は、ステップＳ１４での加算を経た障害発生回数を、ステップＳ１１での加算を経た障害情報確認回数で除算し、障害発生率を算出する（ステップＳ１５）。
When the occurrence of a failure is confirmed (step S13, Yes), the failure information calculation unit 5 adds 1 to the number of failure occurrences held in the failure information statistical data 7 for the node 10 where the failure occurred and the content of the failure ( Step S14). Next, the failure information calculation unit 5 divides the number of failure occurrences after the addition at step S14 by the failure information confirmation number after the addition at step S11, and calculates a failure occurrence rate (step S15).
障害の発生が確認されなかった場合（ステップＳ１３、Ｎｏ）、障害情報演算部５は、ノード１０ごとの各障害内容について障害情報統計データ７が保持する障害発生回数を、ステップＳ１１での加算を経た障害情報確認回数で除算し、障害発生率を算出する（ステップＳ１５）。このように、障害情報演算部５は、障害情報演算工程であるステップＳ１４およびＳ１５により障害情報２の演算処理を実施し、障害発生回数および障害発生率を算出する。
If the occurrence of a failure is not confirmed (No at Step S13), the failure information calculation unit 5 adds the number of failure occurrences held in the failure information statistical data 7 for each failure content for each node 10 at Step S11. The failure occurrence rate is calculated by dividing by the number of failure information confirmations passed (step S15). As described above, the failure information calculation unit 5 performs the calculation process of the failure information 2 in steps S14 and S15 which are failure information calculation steps, and calculates the number of failure occurrences and the failure occurrence rate.
次に、障害情報演算部５は、障害情報統計データ記録工程において、ノード１０ごとに、障害の内容別の障害発生率を、障害情報統計データ７に格納する（ステップＳ１６）。
Next, in the failure information statistical data recording step, the failure information calculation unit 5 stores the failure occurrence rate for each node 10 in the failure information statistical data 7 for each node 10 (step S16).
障害情報取得部４は、取得した全ての障害情報２の確認が終了したか否かを判断する（ステップＳ１７）。未確認の障害情報２があった場合（ステップＳ１７、Ｎｏ）、障害情報処理装置３は、ステップＳ１２からの処理を繰り返す。全ての障害情報２の確認が終了した場合（ステップＳ１７、Ｙｅｓ）、障害情報処理装置３は、障害情報２の処理を終了する。
The failure information acquisition unit 4 determines whether or not all of the acquired failure information 2 has been confirmed (step S17). If there is unconfirmed failure information 2 (No at Step S17), the failure information processing apparatus 3 repeats the processing from Step S12. When the confirmation of all the failure information 2 is completed (step S17, Yes), the failure information processing apparatus 3 ends the processing of the failure information 2.
なお、障害情報演算部５は、障害発生回数および障害発生率の少なくとも一方を障害情報統計データ７として記録するものであれば良いものとする。障害情報統計データ７は、障害発生回数および障害発生率のうち、例えば障害発生回数のみを含むものとしても良い。障害情報統計データ７は、障害発生回数、障害発生率および障害情報確認回数以外の情報を適宜含めることとしても良い。

The failure information statistical data 7 may appropriately include information other than the failure occurrence count, failure occurrence rate, and failure information confirmation count.

The display device 8 reads out the number of times of failure occurrence for each node 10 from the failure information statistical data 7 stored in the internal memory 6 and displays it as a bar graph.

For example, in the example shown in FIG. 3, the display device 8 displays the number of failure occurrences for each of the nodes # 1 to # 4 as a bar graph. In the bar graph, the horizontal axis represents the type of the node 10, and the vertical axis represents the number of failure occurrences. In addition, the display device 8 displays, for example, the color of the number of fault occurrences for each fault A to D in each bar graph.
表示装置８は、障害の内容ごとの障害発生回数を表示する手法は、適宜変更しても良い。表示装置８は、棒グラフ以外のグラフ方式により障害発生回数を表示しても良い。また、表示装置８は、障害情報統計データ７のうち障害発生回数以外に、例えば障害発生率を表示しても良い。表示装置８は、これらのデータを組み合わせてグラフィック表示することとしても良い。
The display device 8 may appropriately change the method of displaying the number of failure occurrences for each failure content. The display device 8 may display the number of failure occurrences by a graph method other than the bar graph. Further, the display device 8 may display, for example, a failure occurrence rate in addition to the failure occurrence frequency in the failure information statistical data 7. The display device 8 may combine these data and display the graphic.
なお、表示装置８は、障害情報統計データ７をグラフ方式により表示する場合に限られず、グラフ方式以外の態様、例えば数値による表示等としても良い。表示装置８において障害情報統計データ７をグラフィック表示することで、使用者は、障害の発生状況を視覚により容易に把握することが可能となる。
Note that the display device 8 is not limited to the case where the failure information statistical data 7 is displayed by a graph method, but may be a mode other than the graph method, for example, a numerical display. By displaying the failure information statistical data 7 in a graphic form on the display device 8, the user can easily grasp the occurrence state of the failure visually.
本発明にかかる障害情報処理装置３は、一定周期ごとに障害情報２を取得し、ノード１０ごと、および障害の内容ごとのデータを障害情報統計データ７として蓄積することで、過去の障害発生の傾向を分析することができる。これにより、使用者は、ネットワーク９上にて通信が不安定な箇所等を的確に把握可能となり、障害発生時における効率的なトラブルシュートを実施できる。
The failure information processing apparatus 3 according to the present invention acquires failure information 2 at regular intervals, accumulates data for each node 10 and each failure content as failure information statistical data 7, so that past failure occurrences can be performed. Trends can be analyzed. As a result, the user can accurately grasp a place where communication is unstable on the network 9, and can efficiently perform troubleshooting when a failure occurs.

Also, the user can prevent troubles by comparing the results of analyzing the network operation status regularly with the trend when trouble occurred in the past. For example, by monitoring the number of error occurrences in the primary loop and the secondary loop over a long period of time, it becomes possible to grasp the deterioration of the network cable and the like.
