When the “status icon” (8) is clicked, a screen such as detailed inspection / diagnosis information can be displayed, and the basis for determining the status can be examined in detail.
図４は状態診断方法の流れを示し、その手順は以下ように説明する。 FIG. 4 shows the flow of the state diagnosis method, and the procedure will be described as follows.
ステップＡ：状態判定基準を点検診断の準備（測定点の決定、測定または点検周期の決定、特徴パラメータの決定など）を行い、図５のように、状態判定用の特徴パラメータの絶対値の状態判定基準を「正常の限界値＜注意の閾値＜危険の閾値」のように設定する。 Step A: Preparation for inspection diagnosis (determination of measurement points, determination of measurement or inspection period, determination of feature parameters, etc.) as the condition determination criteria, and the state of absolute values of feature parameters for state determination as shown in FIG. The criterion is set as “normal limit value <attention threshold <danger threshold”.
診断用の特徴パラメータは監視対象の状態を反映するものであり、監視対象によって違うが、たとえば、回転機械設備診断の分野では振動信号の実効値、歪度、尖度などが使用される。その絶対値の判定基準は以下のように設定される。 The characteristic parameter for diagnosis reflects the state of the monitoring target and varies depending on the monitoring target. For example, in the field of diagnosis of rotating machine equipment, the effective value, the skewness, the kurtosis, etc. of the vibration signal are used. The criterion for determining the absolute value is set as follows.
「正常の限界値」：監視対象の状態が正常であれば、特徴パラメータの絶対値が「正常の限界値」を超えるのは確率的に低い。 “Normal limit value”: If the state of the monitoring target is normal, it is probabilistically low that the absolute value of the characteristic parameter exceeds the “normal limit value”.
「注意の閾値」：監視対象の状態が中度な異常状態時に、特徴パラメータの絶対値が「注意の閾値」以上かつ「危険の閾値」以下になる可能性は確率的に高い。 “Caution threshold”: The probability that the absolute value of the characteristic parameter is greater than or equal to the “caution threshold” and less than or equal to the “danger threshold” in the abnormal state where the state of the monitoring target is medium is probabilistically high.
「危険の閾値」：監視対象の状態が重度な異常状態時に、特徴パラメータの絶対値が「危険の閾値」を超える可能性は確率的に高い。 “Danger threshold”: The probability that the absolute value of the characteristic parameter exceeds the “danger threshold” is probabilistically high when the monitoring target is in a severe abnormal state.
ステップＢ：信号測定または点検を行い、必要なときに診断報告書や状態傾向管理グラフを作成して出力する。 Step B: Perform signal measurement or inspection, and create and output a diagnostic report and state trend management graph when necessary.
ステップＣ：状態監視・診断プログラムを実行し、信号採取器（２）で収集した信号を用いて、特徴パラメータの絶対値を計算し、下記の手順に従って状態判定を行う。 Step C: The state monitoring / diagnosis program is executed, the absolute value of the feature parameter is calculated using the signal collected by the signal collector (2), and the state is determined according to the following procedure.
（ａ） 前記特徴パラメータの絶対値が「正常の限界値」以下であれば、監視対象の状態を正常状態と判定し、状態診断の結果をディスプレー（４）上に正常状態（たとえば、「正常」）と示し、判定基準の見直しを行い、念のために異常があるか否かという精密診断を行う場合もあり、ステップＢへ戻る。 (A) If the absolute value of the characteristic parameter is equal to or less than the “normal limit value”, the monitoring target state is determined to be a normal state, and the result of the state diagnosis is displayed on the display (4) in a normal state (for example, “normal” )), The determination criteria are reviewed, and a precise diagnosis may be performed to determine whether there is an abnormality just in case, and the process returns to Step B.
（ｂ） 前記特徴パラメータの絶対値が「正常の限界値」以上然も「注意の閾値」以下然も急上昇でなく然も継続上昇でなければ、監視対象の状態を軽度な異常状態と判定し、状態診断の結果をディスプレー（４）上に軽度な異常状態（たいとえば、「異常」）と示し、必要なときに異常種類を同定する精密診断を行い、状態判定基準を見直してステップＢへ戻る。 (B) If the absolute value of the characteristic parameter is greater than the “normal limit value” or less than the “caution threshold value” and is not rapidly rising and is not continuously rising, the monitoring target state is determined to be a mild abnormal state. The result of the condition diagnosis is shown as a slight abnormal condition (for example, “abnormal”) on the display (4), a precise diagnosis is performed to identify the type of abnormality when necessary, and the condition determination criteria are reviewed and step B Return to.
なお、急上昇とは図６に示すように、特徴パラメータの絶対値が前回までの上昇傾向と比べ明らかに急に上昇することである。急上昇は、監視対象によって上昇の程度が違うので、一概に数値的に定義することが困難であるが、前回までの傾向と比べて決定することが必要である。 Note that, as shown in FIG. 6, the sudden increase means that the absolute value of the characteristic parameter is clearly increased compared with the upward trend up to the previous time. A sudden rise is difficult to define numerically in general because the degree of rise varies depending on the monitoring target, but it is necessary to determine it compared to the previous trend.
また、継続上昇とは図６に示すように、特徴パラメータの絶対値が３回以上継続的に上昇することである。 Further, the continuous increase means that the absolute value of the characteristic parameter continuously increases three or more times as shown in FIG.
（ｃ） 前記特徴パラメータの絶対値が「正常の限界値」以上然も「注意の閾値」以下然も急上昇でなく然も継続上昇であれば、監視対象の状態を中度な異常状態と判定し、状態診断の結果をディスプレー（４）上に中度な異常状態（たとえば、「注意」）と示し、異常種類を同定する精密診断を行い、点検または測定の周期短縮を検討してステップＢへ戻る。 (C) If the absolute value of the characteristic parameter is greater than or equal to “normal limit value” or less than or equal to the “attention threshold value” but does not increase rapidly but continues to increase, the monitoring target state is determined to be a moderately abnormal state. Then, the result of the state diagnosis is shown as a moderately abnormal state (for example, “Caution”) on the display (4), a precise diagnosis for identifying the type of abnormality is performed, and the inspection or measurement cycle shortening is considered and step B is performed. Return to.
（ｄ） 前記特徴パラメータの絶対値が「正常の限界値」以上然も「注意の閾値」以下然も急上昇であれば、監視対象の状態を中度な異常状態と判定し、状態診断の結果をディスプレー（４）上に中度な異常状態（たとえば、「注意」）と示し、異常種類を同定する精密診断を行い、点検または測定の周期短縮を検討してステップＢへ戻る。 (D) If the absolute value of the characteristic parameter rises above the “normal limit value” and below the “attention threshold value”, the state of the monitoring target is determined as a moderate abnormal state, and the result of the state diagnosis Is displayed as a moderately abnormal state (for example, “Caution”) on the display (4), a precise diagnosis for identifying the type of abnormality is performed, and the inspection or measurement cycle shortening is considered, and the process returns to Step B.
（ｅ） 前記特徴パラメータの絶対値が「注意の閾値」以上然も「危険の閾値」以下然も急上昇でなく然も注意の閾値超過後、継続上昇でなければ、監視対象の状態を中度な異常状態と判定し、状態診断の結果をディスプレー（４）上に中度な異常状態（たとえば、「注意」）と示し、異常種類を同定する精密診断を行い、点または測定の検周期短縮を検討してステップＢへ戻る。 (E) If the absolute value of the characteristic parameter is not more than a “caution threshold” or less than a “danger threshold”, and if it does not continue to rise after the attention threshold is exceeded, the state of the monitoring target is moderate The abnormal condition is judged, the result of the condition diagnosis is shown as a moderate condition (for example, “Caution”) on the display (4), a precise diagnosis is performed to identify the type of abnormality, and the point or measurement cycle is shortened. And return to Step B.
（ｆ） 前記特徴パラメータの絶対値が「注意の閾値」以上然も「危険の閾値」以下然も急上昇でなく然も注意の閾値超過後、継続上昇であれば、監視対象の状態を重度な異常状態と判定し、状態診断の結果をディスプレー（４）上に重度な異常状態（たとえば、「危険」）と示し、異常種類を同定する精密診断を行い、監視強化のために点検周期短縮を検討し、即時に措置を取るか否かを決定してステップＢへ戻る。 (F) If the absolute value of the feature parameter is not more than a “caution threshold” or less than a “danger threshold”, and if the feature parameter continues to increase after the attention threshold is exceeded, the state of the monitoring target is serious. It is judged as an abnormal state, the result of the state diagnosis is shown as a severe abnormal state (for example, “danger”) on the display (4), a precise diagnosis is performed to identify the type of abnormality, and the inspection cycle is shortened to strengthen monitoring. Review and decide whether to take immediate action and return to Step B.
（ｇ） 前記特徴パラメータの絶対値が「注意の閾値」以上然も「危険の閾値」以下然も急上昇であれば、監視対象の状態を緊急に措置を取らなければならない重度な異常と判定し、状態診断の結果をディスプレー（４）上に緊急に措置を取らなければならない重度な異常（たとえば、「危険」または「停止」）と示し、即時の措置を取ってステップＢへ戻る。 (G) If the absolute value of the characteristic parameter is a sharp increase above the “caution threshold” or below the “danger threshold”, it is determined that the monitored state is a serious abnormality that requires urgent action. The result of the condition diagnosis is indicated as a serious abnormality (for example, “danger” or “stop”) that must be taken urgently on the display (4), and the immediate action is taken and the process returns to step B.
（ｈ） 前記特徴パラメータの絶対値が「危険の閾値」以上であれば、監視対象の状態を緊急に措置を取らなければならない重度な異常と判定し、状態診断の結果をディスプレー（４）上に緊急に措置を取らなければならない重度な異常（たとえば、「危険」または「停止」）と示し、即時の措置を取ってステップＢへ戻る。 (H) If the absolute value of the characteristic parameter is equal to or greater than the “danger threshold”, it is determined that the monitored state is a serious abnormality that requires urgent action, and the result of the state diagnosis is displayed on the display (4). Indicates a serious abnormality (for example, “danger” or “stop”) that must be taken urgently, take immediate action, and return to step B.

を特徴とする状態監視方法。Using the state monitoring system according to claim 1, as a state diagnosis procedure,
Step A: Prepare the condition criteria for inspection / diagnosis (measurement point determination, measurement or inspection cycle determination, feature parameter determination, etc.). Limit value <attention threshold <danger threshold>
Step B: Perform signal measurement or inspection, and create and output diagnostic reports and status trend management graphs when necessary.
Step C: executing the state monitoring / diagnostic program, calculating an absolute value of the feature parameter using the signal collected by the signal collector (2), and performing state determination according to the following procedure:
(A) If the absolute value of the characteristic parameter is equal to or less than the “normal limit value”, the monitoring target state is determined to be normal, and the display (4) indicates a normal state (or “normal”). There may be a precise diagnosis of whether or not there is, review the condition criteria, and return to Step B.
(B) If the absolute value of the characteristic parameter is greater than or equal to “normal limit value” or less than or equal to the “attention threshold value” and does not increase rapidly, it is determined that the monitored state is a mild abnormal condition. The display (4) shows a mild abnormal condition (or “abnormal”), performs a precise diagnosis to identify the type of abnormality when necessary, reviews the condition criteria, and returns to step B.
(C) If the absolute value of the characteristic parameter is greater than or equal to “normal limit value” or less than or equal to the “attention threshold value” but does not increase rapidly but continues to increase, the monitoring target state is determined to be a moderately abnormal state. The display (4) shows a moderate abnormal condition (or “caution”), performs a precise diagnosis to identify the type of abnormality, considers shortening the inspection or measurement cycle, and returns to step B.
(D) If the absolute value of the feature parameter rises rapidly above the “normal limit value” or below the “attention threshold value”, the monitoring target state is determined to be a moderately abnormal state, and the display (4) Indicate a moderately abnormal condition (or “caution”), perform a precise diagnosis to identify the type of abnormality, consider shortening the inspection or measurement cycle, and return to Step B.
(E) If the absolute value of the characteristic parameter is greater than or equal to the “attention threshold” or less than the “danger threshold”, and does not continue to rise after the attention threshold is exceeded, the monitoring target state is moderate. It is determined that the abnormal condition is present, and the display (4) shows a moderate abnormal condition (or “Caution”). A precise diagnosis is performed to identify the type of abnormality. Going back,
(F) If the absolute value of the feature parameter is not more than a “caution threshold” or less than a “danger threshold”, and if it continues to rise after the attention threshold is exceeded, the state of the monitoring target is serious. Judged as an abnormal condition, indicated a severe abnormal condition (or “danger”) on the display (4), performed a precise diagnosis to identify the type of abnormality, examined shortening of the inspection cycle to strengthen monitoring, and immediately implemented measures Decide whether to take and return to step B,
(G) If the absolute value of the feature parameter is higher than the “caution threshold” or less than the “danger threshold”, it is determined that the state to be monitored is a serious abnormal state that requires urgent action. The display (4) indicates a serious abnormal condition (or “emergency” or “stop”) that must be taken urgently, take immediate action and return to step B;
(H) If the absolute value of the characteristic parameter is equal to or greater than the “danger threshold”, it is determined that the state of the monitoring target is a serious abnormal state that requires urgent action, and the urgent action is taken in the display (4). Indicate a severe abnormal condition (or “emergency” or “stop”) that must be taken, take immediate action and return to step B;
A state monitoring method characterized by the above.
