此外,診斷部74係根據所取得的測定資訊56,診斷X線厚度測定裝置12的異常。具體而言,診斷部74係根據測定資訊56,求出測定資訊56的突波的發生頻度、與該突波的大小的積。接著,診斷部74係根據所求出的積,判定X線厚度測定裝置12的異常位準。在此,異常位準係X線厚度測定裝置12接近故障狀態的位準。Further, the diagnosis unit 74 diagnoses the abnormality of the X-ray thickness measurement device 12 based on the acquired measurement information 56 . Specifically, based on the measurement information 56 , the diagnosis unit 74 obtains the product of the frequency of occurrence of the surge in the measurement information 56 and the magnitude of the surge. Next, the diagnosis unit 74 determines the abnormal level of the X-ray thickness measuring apparatus 12 based on the obtained product. Here, the abnormal level is a level at which the X-ray thickness measuring apparatus 12 is close to the failure state.
藉由實驗結果,可知在測定資訊56的突波係存在離散發生的非常大的突波、及連續發生的較小的突波等2個類型的突波。因此,X線厚度測定裝置12的異常位準係以考慮測定資訊56的突波的發生頻度、與該突波的大小之雙方來進行判定為佳。From the experimental results, it was found that there are two types of surges in the surge system of the measurement information 56, namely, a very large surge that occurs discretely, and a smaller surge that occurs continuously. Therefore, the abnormal level of the X-ray thickness measuring apparatus 12 is preferably determined in consideration of both the frequency of occurrence of the surge in the measurement information 56 and the magnitude of the surge.
因此,診斷部74係如上所述,根據測定資訊56的突波的發生頻度、與該突波的大小的積,判定X線厚度測定裝置12的異常位準。藉此,即使在測定資訊56發生離散發生之非常大的突波、及連續發生之較小的突波的任何類型的突波的情形下,亦可使雙方的類型的突波的檢測結果反映在X線厚度測定裝置12的異常位準的判定。結果,可使X線厚度測定裝置12的異常位準的判定精度提升。Therefore, the diagnosis unit 74 determines the abnormal level of the X-ray thickness measuring apparatus 12 based on the product of the frequency of occurrence of the spurious wave in the measurement information 56 and the magnitude of the spurious wave as described above. In this way, even when the measurement information 56 generates a very large surge that occurs discretely and a small surge that occurs continuously, the detection results of both types of surges can be reflected. Determination of abnormal level in the X-ray thickness measuring device 12 . As a result, the determination accuracy of the abnormal level of the X-ray thickness measuring device 12 can be improved.
在本實施形態中,診斷部74係首先由所取得的測定資訊56,將移行期間資料去除。在此,移行期間資料係使測定資訊56(例如管電壓)改變的移行期間內的測定資訊56。例如,診斷部74係在所取得的測定資訊56之中,由初期的測定資訊56將移行期間資料去除。在此,初期的測定資訊56係例如X線厚度測定裝置12起動後,至經過預先設定的時間(例如1分鐘、10分鐘)為止的測定資訊56。In the present embodiment, the diagnosis unit 74 first removes the transition period data from the acquired measurement information 56 . Here, the transition period data is the measurement information 56 in the transition period in which the measurement information 56 (eg, the tube voltage) is changed. For example, the diagnosis unit 74 removes the transition period data from the initial measurement information 56 in the acquired measurement information 56 . Here, the initial measurement information 56 is, for example, the measurement information 56 until a preset time (eg, 1 minute, 10 minutes) elapses after the X-ray thickness measurement device 12 is activated.
接著,診斷部74係如下述式(1)所示,將去除移行期間資料後的初期的測定資訊56所包含的最大值與最小值的差,設定在測定資訊56的變動範圍。在本實施形態中,診斷部74係每100ms設定測定資訊56的變動範圍。此外,診斷部74係由測定資訊56的變動範圍將離群值去除。接著,診斷部74係作成將離群值去除後的變動範圍的修華特管制圖或R管制圖,而且對該修華特管制圖或R管制圖進行失真補正。 變動範圍=(測定資訊56的最大值)-(測定資訊56的最小值)…(1) Next, the diagnosis unit 74 sets the difference between the maximum value and the minimum value included in the initial measurement information 56 after removing the transition period data as the following formula (1) as the variation range of the measurement information 56 . In the present embodiment, the diagnosis unit 74 sets the fluctuation range of the measurement information 56 every 100 ms. In addition, the diagnosis unit 74 removes outliers from the variation range of the measurement information 56 . Next, the diagnosis unit 74 creates a Schwart control map or an R control map of the fluctuation range after removing the outliers, and performs distortion correction on the Schwart control map or the R control map. Variation range = (maximum value of measurement information 56) - (minimum value of measurement information 56)...(1)
接著,診斷部74係根據已進行失真補正的修華特管制圖或R管制圖,求出測定資訊56的變動範圍的上限管理界限UCL及下限管理界限LCL。藉此,即使在測定資訊56包含有不需要的資料、或在測定資訊56包含有失真的情形下,亦可使用已進行失真補正的修華特管制圖或R管制圖,求出適當的上限管理界限UCL及下限管理界限LCL,且檢測測定資訊56的突波。結果,可使X線厚度測定裝置的異常位準的判定精度提升。診斷部74係針對測定資訊56所包含的驅動電壓、驅動電流、管電壓、管電流、及檢測值的各個的變動範圍,求出上限管理界限UCL及下限管理界限LCL者。Next, the diagnosis unit 74 obtains the upper limit management limit UCL and the lower limit management limit LCL of the fluctuation range of the measurement information 56 based on the distortion-corrected Schwart control chart or the R control chart. In this way, even when the measurement information 56 includes unnecessary data or the measurement information 56 includes distortion, it is possible to obtain an appropriate upper limit by using the distortion-corrected Schwart chart or R chart. The management limit UCL and the lower limit management limit LCL are detected, and the surge of the measurement information 56 is detected. As a result, the determination accuracy of the abnormal level of the X-ray thickness measuring apparatus can be improved. The diagnosis unit 74 obtains the upper limit management limit UCL and the lower limit management limit LCL for each variation range of the drive voltage, drive current, tube voltage, tube current, and detection value included in the measurement information 56 .
之後,診斷部74係在突波的檢測對象的測定資訊56之中,檢測變動範圍超過上限管理界限UCL或下限管理界限LCL的測定資訊56作為突波。在此,突波的檢測對象的測定資訊56係例如X線厚度測定裝置12起動後,經過預先設定的時間後的測定資訊56。After that, the diagnosis unit 74 detects the measurement information 56 whose fluctuation range exceeds the upper limit management limit UCL or the lower limit management limit LCL as a surge among the measurement information 56 of the detection target of the surge. Here, the measurement information 56 of the detection target of the spurious wave is, for example, the measurement information 56 after a predetermined time has elapsed after the X-ray thickness measurement device 12 is activated.
此外,診斷部74係生成表示X線厚度測定裝置12的異常位準的指示器(indicator)(以下稱為位準計),且使顯示部73顯示該所生成的位準計。顯示部73係顯示由預兆資料伺服器14被輸出的預兆資料68、或位準計等各種資訊。In addition, the diagnosis unit 74 generates an indicator (hereinafter referred to as a level gauge) indicating an abnormal level of the X-ray thickness measuring device 12 , and causes the display unit 73 to display the generated level gauge. The display unit 73 displays various information such as the omen data 68 output from the omen data server 14 and a level meter.
維護側記憶部72係具有:ROM、RAM、及HDD等主記憶裝置及輔助記憶裝置。維護側記憶部72係記憶維護側處理部70所執行的維護程式76等。維護程式76亦可記憶在CD-ROM或DVD-ROM等可藉由電腦讀取的記憶媒體來提供,亦可透過網際網路等網路來提供。The maintenance-side memory unit 72 includes a main memory device such as a ROM, a RAM, and an HDD, and an auxiliary memory device. The maintenance-side storage unit 72 stores the
接著,說明藉由維護裝置16的診斷部74,算出上限管理界限UCL及下限管理界限LCL的處理的具體例。在以下說明中,係說明診斷部74算出作為測定資訊56之一例的管電壓TV的上限管理界限UCL及下限管理界限LCL之例,惟由管電流、驅動電壓、驅動電流、及檢測值,亦同樣地算出上限管理界限UCL及下限管理界限LCL。Next, a specific example of processing for calculating the upper limit management limit UCL and the lower limit management limit LCL by the diagnosis unit 74 of the
首先,說明藉由診斷部74,由初期的管電壓TV(初期的測定資訊56之一例),將移行期間資料去除的處理。First, the process of removing the transition period data from the initial tube voltage TV (an example of the initial measurement information 56 ) by the diagnosis unit 74 will be described.
當將管電壓TV由某設定值變更為別的設定值時,至使藉由管檢測部44所檢測的管電壓TV安定為止,有耗費數秒的情形。因此,診斷部74係當變更管電壓TV的設定值時,將至藉由管檢測部44所檢測的管電壓TV安定為止所需的移行期間的管電壓TV(移行期間資料之一例),由使用在上限管理界限UCL及下限管理界限LCL的算出的管電壓TV去除。但是,若由從預兆資料伺服器14所取得的管電壓TV已去除移行期間資料時,診斷部74亦可未進行由管電壓TV將移行期間資料去除的處理。When the tube voltage TV is changed from a certain set value to another set value, it may take several seconds until the tube voltage TV detected by the
在本實施形態中,診斷部74係使用局部最大值(Local Maxima),由管電壓TV將移行期間資料去除。具體而言,診斷部74係將管電壓TV的平均轉換為絕對梯度值,且根據該絕對梯度值,設定判斷為移行期間資料的管電壓TV的臨限值。接著,診斷部74係在管電壓TV之中,抽出超過該所設定的臨限值的管電壓TV,且在所抽出的管電壓TV之中,將與鄰接的管電壓TV為不同的管電壓TV的集合作為移行期間資料而去除。在此,鄰接的管電壓TV係在可施加於電絲38與靶材40間的管電壓TV的設定值之中,最接近所抽出的管電壓TV的管電壓TV的設定值。In the present embodiment, the diagnosis unit 74 uses the local maxima to remove the transition period data from the tube voltage TV. Specifically, the diagnosis unit 74 converts the average of the tube voltage TV into an absolute gradient value, and sets the threshold value of the tube voltage TV determined as the transition period data based on the absolute gradient value. Next, the diagnosing unit 74 extracts the tube voltage TV exceeding the set threshold value among the tube voltages TV, and sets the tube voltage TV to be different from the adjacent tube voltage TV among the extracted tube voltages TV. The set of TVs is removed as transition period data. Here, the adjacent tube voltage TV is the set value of the tube voltage TV that is closest to the extracted tube voltage TV among the set values of the tube voltage TV that can be applied between the
或者,在本實施形態中,診斷部74係使用批次平均,由管電壓TV,將移行期間資料去除。具體而言,若存在複數可施加於電絲38與靶材40間的管電壓TV的設定值(例如,60kV、80kV、100kV、110kV、120kV、130kV、及140kV),而且各設定值的容許界限為±1kV時,診斷部74係按每個管電壓TV的設定值,算出藉由管檢測部44而實際檢測的管電壓TV(例如200個管電壓TV)的平均。接著,診斷部74係將與針對各管電壓TV的設定值所算出的管電壓TV的平均不相一致的管電壓TV,作為移行期間資料而去除。Alternatively, in the present embodiment, the diagnosis unit 74 uses the batch average to remove the transition period data from the tube voltage TV. Specifically, if there are plural set values of the tube voltage TV that can be applied between the
接著,說明藉由診斷部74,設定初期的管電壓TV的變動範圍的處理之一例。Next, an example of the process of setting the fluctuation range of the initial tube voltage TV by the diagnosis unit 74 will be described.
在本實施形態中,診斷部74係將由預兆資料伺服器14所取得的每100ms的管電壓TV的最小值與最大值的差,設定在管電壓TV的變動範圍。In the present embodiment, the diagnosis unit 74 sets the difference between the minimum value and the maximum value of the tube voltage TV acquired by the omen data server 14 every 100 ms in the variation range of the tube voltage TV.
圖3係用以說明藉由本實施形態之X線厚度測定系統所為之變動範圍的設定處理之一例的圖。在圖3中,縱軸係表示管電壓TV的變動範圍,橫軸係表示可識別按每個預先設定的周期(例如100ms)的管電壓TV的檢測結果的資料點。FIG. 3 is a diagram for explaining an example of the setting process of the variation range by the X-ray thickness measurement system of the present embodiment. In FIG. 3 , the vertical axis represents the fluctuation range of the tube voltage TV, and the horizontal axis represents the data points that can identify the detection result of the tube voltage TV every predetermined period (eg, 100 ms).
在本實施形態中,診斷部74係如圖3所示,將各資料點中的管電壓TV的最大值TVmax與最小值TVmin之間(差),設定在管電壓TV的變動範圍。In this embodiment, as shown in FIG. 3, the diagnosis unit 74 sets the difference (difference) between the maximum value TVmax and the minimum value TVmin of the tube voltage TV in each data point within the range of variation of the tube voltage TV.
接著,說明藉由診斷部74,由初期的管電壓TV的變動範圍中將離群值去除的處理之一例。Next, an example of the process of removing outliers from the fluctuation range of the initial tube voltage TV by the diagnosis unit 74 will be described.
在本實施形態中,診斷部74係由在替換X線發生器30之後經過預先設定的期間為止的管電壓TV的變動範圍,使用四分位數範圍(IQR:Interquartile Range),將離群值去除。具體而言,診斷部74係在管電壓TV的變動範圍之中,將75百分位數(第3四分位數)及25百分位數(第1四分位數)的各個的1.5*IQR的外側的變動範圍作為離群值(異常值)而去除。In the present embodiment, the diagnosis unit 74 uses an interquartile range (IQR: Interquartile Range) to classify outliers from the fluctuation range of the tube voltage TV until a preset period elapses after the
圖4係用以說明藉由本實施形態之X線厚度測定系統所為之離群值的去除處理之一例的圖。在圖4中,縱軸係表示管電壓TV的變動範圍,橫軸係表示可識別按每個預先設定的周期的管電壓TV的檢測結果的資料點。FIG. 4 is a diagram for explaining an example of outlier removal processing by the X-ray thickness measurement system of the present embodiment. In FIG. 4 , the vertical axis represents the fluctuation range of the tube voltage TV, and the horizontal axis represents the data points that can identify the detection result of the tube voltage TV for each preset period.
診斷部74係在管電壓TV的變動範圍之中,將75百分位數及25百分位數的各個1.5*IQR的外側的變動範圍作為離群值而去除。藉此,如圖4所示,可知在將離群值去除的前後,管電壓TV的變動範圍改變,在平常的管電壓TV中亦可能發生的突波由使用在上限管理界限UCL及下限管理界限LCL的算出的管電壓TV被刪除。The diagnosing unit 74 removes, as outliers, the variation ranges outside of each of the 75th percentile and the 25th percentile of 1.5*IQR in the variation range of the tube voltage TV. Thereby, as shown in FIG. 4 , it can be seen that the fluctuation range of the tube voltage TV changes before and after the outliers are removed, and the surge that may occur in the normal tube voltage TV is managed by using the upper limit control limit UCL and the lower limit. The calculated tube voltage TV of the limit LCL is deleted.
此外,在本實施形態中,診斷部74係由在替換X線發生器30之後經過預先設定的時間經過後的管電壓TV的變動範圍,使用截尾平均數(trimmed mean),將離群值去除。具體而言,診斷部74係在將管電壓TV的變動範圍以升序作排序之後,將由最小值及最大值的各個所預先設定的比例的管電壓TV的變動範圍,作為離群值而去除。若藉由取得部62所取得的管電壓TV的資料集為不安定的資料集時、或該管電壓TV的資料集具有極端偏頗的分布時,診斷部74係使用截尾平均數,由管電壓TV的變動範圍將離群值去除。藉此,可作成具有目的的標準差界限的修華特管制圖或R管制圖。In addition, in the present embodiment, the diagnosis unit 74 uses a trimmed mean to classify outliers from the fluctuation range of the tube voltage TV after a predetermined time has elapsed after the replacement of the
由管電壓TV的變動範圍去除離群值時,係可使用上述2個方法的任一者。至經過X線發生器30的生命週期的初期期間為止的管電壓TV係突波非常小,可藉由IQR來去除其離群值。因此,診斷部74係由替換X線發生器30之後經過預先設定的期間為止的管電壓TV的變動範圍,藉由IQR來將離群值去除。When removing outliers from the variation range of the tube voltage TV, either of the two methods described above can be used. The tube voltage TV system surge until the initial period of the life cycle of the
另一方面,若由X線發生器30的生命週期的後半的管電壓TV的變動範圍,藉由IQR將離群值去除時,突波數增加,在上限管理界限UCL及下限管理界限LCL的算出,有被考慮在判定因X線發生器30的生命週期成為後半所致之突波為異常位準的可能性。因此,診斷部74係由替換X線發生器30之後經過預先設定的期間之後的管電壓TV的變動範圍,使用截尾平均數,將離群值去除。On the other hand, if outliers are removed by the IQR in the fluctuation range of the tube voltage TV in the second half of the life cycle of the
接著,說明藉由診斷部74,作成初期的管電壓TV的變動範圍的修華特管制圖或R管制圖的處理。Next, processing by the diagnosis unit 74 to create a Showwart control map or an R control map of the fluctuation range of the initial tube voltage TV will be described.
首先,診斷部74係作成將離群值去除後的變動範圍的修華特管制圖或R管制圖。修華特管制圖及R管制圖係在測定資訊56的統計上的管理中,可簡單使用而且強力的工具。此外,修華特管制圖及R管制圖係廣被利用,且在產業領域中被應用。First, the diagnosing unit 74 creates a Shewart control map or an R control map of the fluctuation range after removing outliers. The Shewart Control Chart and the R Control Chart are simple and powerful tools for the statistical management of the measurement information 56 . In addition, the Shewart control chart and the R control chart are widely used and applied in the industrial field.
但是,修華特管制圖及R管制圖係基於在統計上作管理的測定資訊56的分布為常態分布或大致常態分布的假定。但是,測定資訊56係表示X線發生器30的生命週期的資訊。因此,某期間(例如,X線發生器30的生命週期的後半)的測定資訊56係因X線發生器30劣化,雜訊數增大。因此,測定資訊56的資料集的確率分布常常被表示為傾右的伽瑪分布(gamma distribution)或韋伯分布(Weibull distribution)。However, the Shewart chart and the R chart are based on the assumption that the distribution of the statistically managed measurement information 56 is a normal distribution or a substantially normal distribution. However, the measurement information 56 is information indicating the life cycle of the
圖5係用以說明藉由本實施形態之X線厚度測定系統所為之修華特管制圖或R管制圖的偏度的補正處理之一例的圖。在圖5中,縱軸係表示管電壓TV的檢測結果的數,橫軸係表示管電壓TV的變動範圍。FIG. 5 is a diagram for explaining an example of the correction processing of the skewness of the Wart tube chart or the R tube chart by the X-ray thickness measurement system of the present embodiment. In FIG. 5 , the vertical axis represents the number of detection results of the tube voltage TV, and the horizontal axis represents the fluctuation range of the tube voltage TV.
如圖5所示,離群值已被去除的管電壓TV的變動範圍的分布係藉由比管電壓TV的變動範圍的平均為更大的管電壓TV的變動範圍變多的伽瑪分布或韋伯分布來表示。因此,無須補正修華特管制圖或R管制圖的偏度,而若使用該修華特管制圖或R管制圖來算出上限管理界限UCL及下限管理界限LCL時,有因X線厚度測定裝置12異常所致之突波的檢測精度降低的可能性。As shown in FIG. 5 , the distribution of the variation range of the tube voltage TV from which the outliers have been removed is a gamma distribution or Weber in which the variation range of the tube voltage TV is larger than the average of the variation range of the tube voltage TV. distribution to represent. Therefore, it is not necessary to correct the skewness of the modified Wart control map or the R control map, and if the upper control limit UCL and the lower limit control limit LCL are calculated using the Shewart control map or the R control map, the X-ray thickness measuring device 12. There is a possibility that the detection accuracy of the surge caused by the abnormality will decrease.
因此,在本實施形態中,診斷部74係補正管電壓TV的修華特管制圖或R管制圖的偏度。藉此,可使用根據測定資訊56成為常態分布或大致常態分布的假定所作成的修華特管制圖或R管制圖,算出上限管理界限UCL及下限管理界限LCL。結果,可更高精度檢測因X線厚度測定裝置12的異常所致之突波。Therefore, in the present embodiment, the diagnosing unit 74 corrects the skewness of the Schwart chart or the R chart of the tube voltage TV. Thereby, the upper limit management limit UCL and the lower limit management limit LCL can be calculated using the Schwart control chart or the R control chart created on the assumption that the measurement information 56 becomes a normal distribution or a substantially normal distribution. As a result, the surge due to the abnormality of the X-ray thickness measuring apparatus 12 can be detected with higher accuracy.
具體而言,診斷部74係使用下述式(2)、(3),算出經補正偏度的修華特管制圖的上限管理界限UCL及下限管理界限LCL。在式(2)、(3)中,在R之上橫槓係管電壓TV的變動範圍的平均,T係任意值,d R係修華特管制圖的偏度所補正的值(以下稱為偏度補正值),CL係修華特管制圖的中心線,σ R係管電壓TV的標準偏差,K(R)係管電壓TV的偏度。 Specifically, the diagnosis unit 74 uses the following equations (2) and (3) to calculate the upper limit management limit UCL and the lower limit management limit LCL of the skewness-corrected Schwart control chart. In equations (2) and (3), the horizontal bar above R is the average of the fluctuation range of the tube voltage TV, T is an arbitrary value, and d R is the value corrected for the skewness of the Shewart tube diagram (hereinafter referred to as the is the skewness correction value), CL is the center line of the Schwart tube chart, σ R is the standard deviation of the tube voltage TV, and K(R) is the skewness of the tube voltage TV.
圖6係顯示藉由本實施形態之X線厚度測定系統所作成的管電壓的R管制圖之一例的圖。在圖6中,縱軸係表示管電壓TV的變動範圍,橫軸係表示可識別每個預先設定的周期的管電壓TV的檢測結果的資料點。FIG. 6 is a diagram showing an example of an R-control chart of tube voltage created by the X-ray thickness measurement system of the present embodiment. In FIG. 6 , the vertical axis represents the fluctuation range of the tube voltage TV, and the horizontal axis represents the data points that can identify the detection result of the tube voltage TV for each preset period.
如圖6所示,診斷部74係使用上述式(2)、(3),算出管電壓TV的R管制圖的上限管理界限UCL及下限管理界限LCL。接著,診斷部74係在突波的檢測對象的管電壓TV之中,檢測變動範圍超過上限管理界限UCL或下限管理界限LCL的管電壓TV作為突波。As shown in FIG. 6 , the diagnosis unit 74 calculates the upper limit management limit UCL and the lower limit management limit LCL of the R control map of the tube voltage TV using the above equations (2) and (3). Next, the diagnosis unit 74 detects, as a surge, the tube voltage TV whose fluctuation range exceeds the upper limit management limit UCL or the lower limit management limit LCL among the tube voltages TV of the detection target of the surge.
接著,說明藉由診斷部74來判定X線厚度測定裝置12的異常位準的處理的具體例。在以下說明中,係說明診斷部74根據管電壓TV的檢測結果,判定X線厚度測定裝置12的異常位準之例,惟關於管電流、驅動電壓、驅動電流、及檢測值,亦同樣地判定X線厚度測定裝置12的異常位準。Next, a specific example of the process of determining the abnormal level of the X-ray thickness measuring apparatus 12 by the diagnosis unit 74 will be described. In the following description, an example in which the diagnosis unit 74 determines the abnormal level of the X-ray thickness measuring device 12 based on the detection result of the tube voltage TV will be described. However, the same applies to the tube current, driving voltage, driving current, and detection value. The abnormal level of the X-ray thickness measuring device 12 is determined.
圖7及圖8係顯示藉由本實施形態之X線厚度測定系統所檢測的管電壓TV的突波之一例的圖。在圖7及圖8中,縱軸係表示管電壓TV的變動範圍,橫軸係表示可識別每個預先設定的周期的管電壓TV的檢測結果的資料點。7 and 8 are diagrams showing an example of the surge of the tube voltage TV detected by the X-ray thickness measurement system of the present embodiment. In FIGS. 7 and 8 , the vertical axis represents the fluctuation range of the tube voltage TV, and the horizontal axis represents the data points that can identify the detection result of the tube voltage TV for each preset period.
管電壓TV的突波的類型主要分為2個類型。1類型係如圖7所示,離散發生較大突波的類型。另一類型係如圖8所示,連續發生較小突波的類型。因此,X線厚度測定裝置12的異常係藉由離散發生的大突波、及連續發生的小突波之雙方來表示。The types of surges of the tube voltage TV are mainly divided into two types. Type 1 is a type in which large surges are generated discretely as shown in Fig. 7 . Another type is a type in which small surges occur continuously as shown in FIG. 8 . Therefore, the abnormality of the X-ray thickness measuring apparatus 12 is indicated by both the large surge that occurs discretely and the small surge that occurs continuously.
因此,診斷部74係根據管電壓TV的突波的發生頻度、與該突波的大小(例如管電壓TV的變動範圍)的積,判定X線厚度測定裝置12的異常位準。藉此,即使在測定資訊56發生離散發生之非常大的突波、及連續發生的較小突波的任何類型的突波的情形下,亦可使雙方類型的突波的檢測結果反映在X線厚度測定裝置12的異常位準的判定。結果,可使X線厚度測定裝置12的異常位準的判定精度提升。Therefore, the diagnosis unit 74 determines the abnormal level of the X-ray thickness measuring apparatus 12 based on the product of the frequency of occurrence of the surge in the tube voltage TV and the magnitude of the surge (eg, the fluctuation range of the tube voltage TV). In this way, even when the measurement information 56 generates a very large surge that occurs discretely, and a small surge that occurs continuously, the detection results of both types of surges can be reflected in X. Determination of the abnormal level of the wire thickness measuring device 12 . As a result, the determination accuracy of the abnormal level of the X-ray thickness measuring device 12 can be improved.
圖9係顯示藉由本實施形態之X線厚度測定系統所檢測的管電壓的突波的發生頻度之一例的圖。在圖9中,縱軸係表示每個預定時間(例如1小時)的管電壓TV的突波的發生頻度,橫軸係表示檢測管電壓TV的突波的時間。FIG. 9 is a diagram showing an example of the frequency of occurrence of a surge in the tube voltage detected by the X-ray thickness measurement system of the present embodiment. In FIG. 9 , the vertical axis represents the frequency of occurrence of the surge of the tube voltage TV at each predetermined time (for example, 1 hour), and the horizontal axis represents the time at which the surge of the tube voltage TV was detected.
