For example, the acquisition unit 311 acquires measurement data from the thickness measurement unit 2 and stores it as the measurement data 321 of the storage unit 32. also. For example, when the self-diagnosis of the thickness measuring unit 2 is executed (controlled) by the self-diagnosis unit 313, the acquisition unit 311 acquires the self-diagnosis result data from the thickness measuring unit 2 and the self-diagnosis result data of the storage unit 32.

The self-diagnosis unit 313 executes (controls) the corresponding self-diagnosis when the measurement control unit 312 determines that the self-diagnosis of the thickness measuring device 1 needs to be executed.

The communication interface 33 is an interface for communicating with the two thickness measuring units 2, the operating PC, and the host computer 5. The number of communication interfaces 33 is provided, for example, as many as the number of communication targets, but only one is shown in FIG. 2 for the sake of brevity.

Next, the operation PC 4 will be described with reference to FIG. FIG. 3 is a block diagram showing an example of the functional configuration of the operation PC 4 of the embodiment. The operation PC 4 is a computer device used by a user of the thickness measuring unit 2 (including a maintenance person or the like) to check log data 322 and collect data. The operation PC 4 is, for example, an HMI (Human Machine Interface).

The operation PC 4 includes a processing unit 41, a storage unit 42, a display unit 43, an input unit 44, an input / output interface 45, and a communication interface 46.

The storage unit 42 includes, for example, a storage device such as a ROM, RAM, or HDD, and stores various types of information. The storage unit 42 stores, for example, data acquired from the control device 3, correspondence information 421, file data 422 generated by the aggregation unit 412, and the like.

FIG. 4 is a diagram showing an example of correspondence information 421 of the embodiment. Correspondence information 421 is the type of data to be acquired (classification 1 data, classification 2 data in FIG. 4) for each of a plurality of types of self-diagnosis (self-diagnosis name in FIG. 4) for diagnosing an abnormality in the thickness measuring unit 2. This is information associated with a period (required data period in FIG. 4).

As shown in FIG. 4, the information in the correspondence information 421 is, in order from the left, the self-diagnosis name, the date and time, the classification 1 data (status data (at the time of executing the self-diagnosis)), the classification 2 data (data that needs to be collected), and necessary. The data period.

The self-diagnosis name is the name of the self-diagnosis performed among the plurality of types of self-diagnosis. As the self-diagnosis name, all calibration requests, all calibration data long-term fluctuations, and Ethernet (registered trademark) communication abnormality are shown here. The date and time is information on the date and time when the self-diagnosis was performed.

The classification 1 data is status data at the time of executing self-diagnosis, and is stored in, for example, self-diagnosis result data 324. Data 1 to 4 are shown here as classification 1 data. The contents of Data 1 to 4 differ depending on the self-diagnosis name. For example, when the self-diagnosis name is all calibration request, Data1 is the calibration point plate thickness (unit: μm), and indicates the plate thickness measured at the time of executing the self-diagnosis. Further, Data2 is a drift amount (unit: μm) at the time of measuring the calibration point.

Further, when the self-diagnosis name has a large long-term fluctuation of all calibration data, Data1 and Data2 are the same as when the self-diagnosis name is all calibration request. Data3 is a total calibration time interval (in minutes), which is a time interval from the previous total calibration implementation.

Further, when the self-diagnosis name is Ethernet communication abnormality, Data1 is an execution processing category, and for example, if it is "Send", it indicates that an abnormality has occurred in the transmission processing from the control device 3 to the host computer 5.

The classification 2 data is data that needs to be collected to create file data 422 (FIG. 3), that is, data that is necessary to analyze the self-diagnosis result, and is originally stored in the thickness measuring unit 2. It is data. As Category 2 data, self-diagnosis history, start-up data, all calibration data, reference dose history, and communication log are shown here. Among them, for example, the self-diagnosis history, startup data, all calibration data, and reference dose history are stored in the self-diagnosis result data 324, and the communication log is stored in the log data 322.

The self-diagnosis history is a list and details of the self-diagnosis that has occurred. The start-up data is all calibration data from the beginning or the first all calibration data after exchanging a part of the thickness measuring unit 2 (X-ray generator 21, detector 22, etc.). The start-up data is data necessary for creating a calibration curve used for measuring the plate thickness in the thickness measuring unit 2, and is a measured value at each calibration point plate thickness. In addition, the start-up data is collected at the time of the first start-up of the thickness measuring unit 2 or at the time of replacing the main parts.

All calibration data is the same type of data as the startup data, but is data in calibration performed every few hours to cancel the drift amount during measurement. The communication log is a history of communication data between the control device 3 and the host computer 5.

For example, when the self-diagnosis name has a large long-term fluctuation of all calibration data, in addition to the status data (Data1, Data2, Data3) of the classification 1 data, the self-diagnosis history, startup data, all calibration data, and reference dose history as classification 2 data. Is the required data.

The required data period is the period for which data is collected, which is predefined for the self-diagnosis performed. Specifically, the required data period defines how long the classification 2 data needs to be collected retroactively (that is, how long ago the data should be viewed in order to investigate the abnormality of the thickness measuring unit 2). It was done. For example, if the self-diagnosis name is a full calibration request, the required data period is from the time the self-diagnosis occurs to one week before. If the self-diagnosis name has a large long-term fluctuation of all calibration data, the required data period is from the time when the self-diagnosis occurs to before <DATA3>. When the self-diagnosis name is Ethernet communication abnormality, the required data period is from the time when the self-diagnosis occurs to the limit (the limit that can be collected).

FIG. 5 is a diagram showing a part of the self-diagnosis result data 324 of the embodiment. As shown in FIG. 5, here, as the self-diagnosis result data 324, the calibration point plate thickness (μm), the drift amount at the time of calibration point measurement (μm), and the total calibration time interval (minutes) are saved for each date and time. ing.

Of these, for example, the calibration point plate thickness (μm) is the data of Data 1 (FIG. 4) when the self-diagnosis name is all calibration request and when all calibration data has a large long-term fluctuation.

The drift amount (unit: μm) at the time of measuring the calibration point is the data of Data2 when the self-diagnosis name is all calibration request and when the long-term fluctuation of all calibration data is large.

Further, the total calibration time interval (minutes) is the data of Data3 when the self-diagnosis name is the total calibration data with a large long-term fluctuation.

The control device 3 has the data of the type (classification 1 data, classification 2 data in FIG. 4) associated with (self-diagnosis name in FIG. 4) for the associated period (required data period in FIG. 4). Obtained from the storage unit 32 of.

For example, when the self-diagnosis unit 313 performs a self-diagnosis of all calibration requests (self-diagnosis name in FIG. 4), the acquisition unit 411 refers to the correspondence information 421 and refers to the correspondence information 421 as the associated type of data in FIG. Corresponds to DATA1 in Category 1 data, data of DATA2 in FIG. 4, self-diagnosis history of Category 2 data, startup data, all calibration data, and reference dose history (data marked with a circle in FIG. 4).
