  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic block diagram showing a functional configuration of a repair work support apparatus according to an embodiment of the present invention. In the figure, the repair work support apparatus 100 includes a display unit 110, an input unit 120, a communication unit 130, a storage unit 180, and a control unit 190. The storage unit 180 includes a damage data storage unit 181, a repair reference data storage unit 182, and a damage comprehensive evaluation data storage unit 183. The control unit 190 includes a data management unit 191, a comprehensive evaluation value calculation unit 192, and a repair policy determination unit 193.

The repair work support apparatus 100 determines whether or not repair is necessary based on information on damage in the inspection target. The term “repair” as used herein refers to treatment for a deteriorated part or an old part. Parts replacement may be performed as a repair. Further, the damage here can be various. For example, the damage may include cracks, thinning, dents, blockages, coating peeling, and the like.
In the following, a case where the repair work support apparatus 100 determines whether or not a gas turbine part needs to be repaired will be described as an example. However, the repair work support apparatus 100 is not limited to a gas turbine part, and various devices or The necessity of repair can be determined for the parts of the plant.

The display unit 110 has a display screen such as a liquid crystal panel or an organic EL (Organic Electroluminescence) panel, and displays various images according to the control of the control unit 190. For example, the display unit 110 displays a determination result of whether repair is necessary.
The input unit 120 has an input device such as a keyboard or a mouse, or a touch sensor that is provided on the display screen of the display unit 110 and forms a touch panel, and accepts user operations. For example, the input unit 120 accepts a user operation for instructing whether or not repair is necessary, an inspection record input operation, and the like.
The communication unit 130 communicates with other devices. For example, the communication unit 130 acquires maintenance reference data indicating a criterion for determining whether or not repair is necessary from another device such as a maintenance inspection data management server device.

The storage unit 180 stores various data. The storage unit 180 is configured using a storage device that the repair work support apparatus 100 has.
The damage data storage unit 181 stores damage data that is data of each damage detected in the inspection. More specifically, the damage data storage unit 181 stores damage data in which damage types, damage measurement targets, and measurement values are associated with each other for each damage. In particular, the damage data storage unit 181 stores damage data in which an area and a damage type are associated with each other as a damage type.

  FIG. 2 is an explanatory diagram illustrating an example of damage data stored in the damage data storage unit 181. In the figure, the damage data is shown in a table format, and one line corresponds to one damage. The data in each row includes a “No.” column, a “damage type” column, a “measurement value” column, and a “repair determination flag” column.

The “No.” column stores identification information (for example, serial number) for each damage.
The “Damage type” column is a column for storing information for classifying the damage, the “Damage type” column for storing the type of damage (damage form), and the “Damage type” column for storing the area including the damage. And a “region” column.

The “measured value” column stores the measured value of damage obtained in the inspection. In FIG. 2, as examples of measured values, damage length (L), damage width (W), damage depth (D), diameter (φ) when the damage is circular, Although the distance to the nearest other damage and the number of damages are shown, this is not restrictive.
Note that the measurement value here may be a count value such as the number of damages. The measured value here is not limited to the directly measured value such as the length and width shown in FIG. 2, but is a value measured based on the directly measured value (for example, calculated from the directly measured value). Value). For example, the measured value here may be an area obtained by multiplying the length and the width, or may be an area calculated from the radius or diameter of a circle. Alternatively, the measurement value here may be a volume or volume obtained by multiplying the length, width, and depth.

In addition, the value to be measured at the time of inspection is determined for each type of damage, and the damage data storage unit 181 stores the minimum value “0” for values that are not measured. For example, in the case of a crack, the length is the object to be measured. Therefore, the damage data storage unit 181 stores actually measured values for the crack length and “0” for the width, depth, and the like.
The “repair determination flag” column stores a repair determination flag indicating a determination result of whether or not repair is necessary. For example, the repair determination flag value “1” indicates that repair is necessary, and the value “0” indicates that repair is not required. The example of FIG. 2 shows damage data in a state before determining whether or not repair is necessary, and the values of the repair determination flags are all the initial value “0”.

  The repair reference data storage unit 182 stores repair reference data in which a damage type, a damage measurement target, and a damage evaluation reference value are associated with each other. In particular, the repair reference data storage unit 182 stores repair reference data in which a region and a damage type are associated with each other as a damage type.

  FIG. 3 is an explanatory diagram illustrating an example of repair reference data stored in the repair reference data storage unit 182. In the figure, repair standard data is shown in a table format, and one line corresponds to one judgment standard (judgment standard for each type of damage). Each row of data includes a “No.” column, a “damage type” column, and a “judgment reference value” column.

The “No.” column stores identification information (for example, a serial number) of determination criteria.
The “type of damage” column is the same as in the case of damage data (see FIG. 2). The repair policy decision unit 193 applies to each damage by searching for a line in which both “area” and “type of damage” match from the repair standard data for each line of damage data in the determination of necessity of repair. Select the criteria to be used.

The “judgment reference value” column stores a threshold value that serves as a judgment criterion for whether or not repair is necessary. In FIG. 3, the damage length (L), the damage width (W), the damage depth (D), the damage area (S), and the number of damages are shown as examples of the criterion values. However, it is not limited to this. The determination reference value stored in the repair reference data storage unit 182 may correspond to the measurement value stored in the damage data storage unit 181 or a value derivable from the measurement value.
Further, the repair reference data storage unit 182 stores a maximum value (for example, “999” for the length and “9999” for the area) for the reference value corresponding to the value not measured at the time of inspection.

The damage comprehensive evaluation data storage unit 183 stores damage comprehensive evaluation data indicating comprehensive evaluation values for comprehensively evaluating damage data stored in a plurality of columns of damage data (see FIG. 2).
FIG. 4 is an explanatory diagram illustrating an example of damage comprehensive evaluation data stored in the damage comprehensive evaluation data storage unit 183. In the figure, the damage comprehensive evaluation data is shown in a table form, and one line corresponds to one comprehensive evaluation value. Each row of data includes a “No.” column, a “repair reference table record No.” column, and a “calculated value” column.

The “No.” column stores identification information (for example, a serial number) of the comprehensive evaluation value.
The “repair criteria table record No.” column stores information indicating the type of damage to be subjected to comprehensive evaluation.
In the example of FIG. 4, the “repair criteria table record No.” column indicates the type of damage in the corresponding row by storing the identification information of the determination criteria in the repair criteria data (see FIG. 3). For example, the damage comprehensive evaluation data of FIG. In row 1, repair criteria table record No. "4" is stored as No. in the repair standard data. By indicating the link to the row 4, the type of damage by the combination of region = “chip” and type of damage = “crack” is shown.

However, the method of indicating the type of damage in the damage comprehensive evaluation data is not limited to this. For example, as in the case of FIGS. 2 and 3, the type and area of damage may be clearly indicated.
The “calculated value” column stores a calculated value calculated by a comprehensive evaluation value calculating unit 192, which will be described later, as a comprehensive evaluation value for comprehensively evaluating damage data stored in a plurality of columns of damage data (see FIG. 2). To do. The initial value in the “calculated value” column is 0.

The control unit 190 controls each unit of the repair work support apparatus 100 to execute various functions. In particular, the control unit 190 determines whether repair is necessary based on data stored in the storage unit 180.
The control unit 190 is realized, for example, when a CPU (Central Processing Unit) included in the repair work support apparatus 100 reads out and executes a program from the storage unit 180.

The data management unit 191 manages data stored in the storage unit 180, such as writing data to the storage unit 180, searching, and reading data from the storage unit 180. In particular, the data management unit 191 corresponds to an example of a damage data acquisition unit, and acquires damage data by reading out damage data from the damage data storage unit 181.
However, the method by which the damage data acquisition unit acquires damage data is not limited to this. For example, the communication unit 130 may acquire damage data from another device such as a maintenance inspection data management server device. In this case, the communication unit 130 corresponds to an example of a damage data acquisition unit. Alternatively, the input unit 120 may accept an input operation for damage data, and the control unit 190 may determine whether repair is necessary by directly using the damage data obtained by the input operation. In this case, the input unit 120 corresponds to an example of a damage data acquisition unit.

  The comprehensive evaluation value calculation unit 192 calculates a comprehensive evaluation value obtained by comprehensively evaluating measured values of damage having the same damage type among the damage data read from the damage data storage unit 181 by the data management unit 191. Specifically, the comprehensive evaluation value calculation unit 192 calculates the total evaluation value by summing the measured values of damage having the same damage type among the damage data read by the data management unit 191 from the damage data storage unit 181. calculate.

  Note that the comprehensive evaluation value calculated by the comprehensive evaluation value calculation unit 192 is not limited to a value obtained by comprehensively evaluating values directly measured such as length and width, but is a value measured based on a direct measurement value (for example, directly (A value calculated from a typical measurement value) may be a comprehensive evaluation value. For example, the comprehensive evaluation value calculated by the comprehensive evaluation value calculation unit 192 may be a value obtained by comprehensively evaluating an area obtained by multiplying the length and the width, or may be an area calculated from the radius or diameter of a circle. It may be a comprehensively evaluated value. Alternatively, the comprehensive evaluation value calculated by the comprehensive evaluation value calculation unit 192 may be a value obtained by comprehensively evaluating a volume or a volume obtained by multiplying the length, the width, and the depth.

As will be described later as a modification of the present embodiment, the comprehensive evaluation value calculated by the comprehensive evaluation value calculation unit 192 is not limited to a simple total value of measurement values, and may be various calculated values by weighting or the like. it can.
The repair policy determination unit 193 compares the measured value read by the data management unit 191 from the damage data storage unit 181 or the comprehensive evaluation value calculated by the comprehensive evaluation value calculation unit 192 with the repair reference data, and repair policy. To decide.

Next, the operation of the repair work support apparatus 100 will be described with reference to FIG.
FIG. 5 is a flowchart showing a processing procedure for determining necessity of repair performed by the repair work support apparatus 100. For example, when the repair operation support apparatus 100 receives a user operation that supports determination of necessity of repair, the repair work support apparatus 100 performs the process of FIG.

In the process of FIG. 5, first, the control unit 190 starts a loop L11 that performs the process for each row of damage data stored in the damage data storage unit 181 (step S111).
And the data management part 191 reads the data of the line used as the process target by the loop L11 from the damage data storage part 181 (step S112). Hereinafter, a row that is a processing target in a loop is referred to as a “target row”.

Next, the data management unit 191 refers to each row of the damage comprehensive evaluation data stored in the damage comprehensive evaluation data storage unit 183 and determines whether there is a row having the same damage type as the target row (step S113).
Specifically, the data management unit 191 sets the repair standard table record No. for each line of the damage comprehensive evaluation data. The link to the repair standard data is followed based on the value of. Then, the data management unit 191 determines whether or not the damage type and the area in the linked line of the repair reference data match the damage type and the area of the target line.
When it is determined that there is a matching row (step S113: YES), the comprehensive evaluation value calculation unit 192 updates the damage comprehensive evaluation data stored in the damage comprehensive evaluation data storage unit 183 (step S121).

FIG. 6 is a flowchart illustrating a processing procedure in which the comprehensive evaluation value calculation unit 192 updates the damage comprehensive evaluation data stored in the damage comprehensive evaluation data storage unit 183. The comprehensive evaluation value calculation unit 192 performs the process of FIG. 6 in step S121 of FIG.
In the process of FIG. 6, the comprehensive evaluation value calculation unit 192 first obtains the calculated value (value in the “calculated value” column) of the line determined to match in step S113 in the damage comprehensive evaluation data (step S211). . Specifically, the data management unit 191 reads out the calculated value (the value in the “calculated value” column) of the line determined to match in the damage comprehensive evaluation data in step S113 and outputs it to the comprehensive evaluation value calculating unit 192. Thus, the comprehensive evaluation value calculation unit 192 acquires the calculated value.

Next, the comprehensive evaluation value calculation unit 192 acquires an actual measurement value (measurement value whose value is not 0) among the measurement values of the target row read by the data management unit 191 in step S112 (step S212).
Then, the comprehensive evaluation value calculation unit 192 adds the calculated value obtained in step S211 and the measured value obtained in step S212 or a value calculated from the measured value (step S213).

Then, the comprehensive evaluation value calculation unit 192 writes the calculation value in step S213 to the damage comprehensive evaluation data storage unit 183 via the data management unit 191 (step S214). Specifically, the comprehensive evaluation value calculation unit 192 outputs the calculated value in step S213 to the data management unit 191. Then, the data management unit 191 rewrites the calculated value read in step S211 with the calculated value from the comprehensive evaluation value calculating unit 192.
After step S214, the process of FIG. 6 ends.

Returning to the processing of FIG. 5, the control unit 190 determines whether or not the processing of the loop L11 has been performed on all the rows of the damage data stored in the damage data storage unit 181, and branch processing is performed according to the determination result. Is performed (step S141). When it is determined that the processing of the loop L11 has been performed for all the rows, the loop L11 is terminated. On the other hand, if it is determined that there is a line that has not been processed yet, the process returns to step S111, and the process of the loop L11 is continued for the unprocessed line.
When the loop L11 is finished in step S141, the repair policy determination unit 193 determines whether or not repair is necessary for each row of the damage comprehensive evaluation data (step S151).

FIG. 7 is a flowchart illustrating a processing procedure in which the repair policy determination unit 193 determines whether or not repair is necessary for each row of the damage comprehensive evaluation data. The repair policy determination unit 193 performs the process of FIG. 7 in step S151 of FIG.
In the process of FIG. 7, the repair policy determination unit 193 first starts a loop L <b> 21 that performs processing for each row of damage comprehensive evaluation data stored in the damage comprehensive evaluation data storage unit 183 (step S <b> 311).

Next, the repair policy determination unit 193 acquires the data of the target row in the damage comprehensive evaluation data via the data management unit 191 (step S312).
Further, the repair policy determination unit 193 includes the repair standard table record No. of the target line acquired in step S312 among the repair standards (determination criteria for repair necessity) indicated by the repair standard data storage unit 182. Is obtained via the data management unit 191 (step S313).

Then, the repair policy determination unit 193 compares the calculated value of the target row acquired in step S312 with the repair standard acquired in step S313, and determines whether repair is necessary (step S314).
Next, the repair policy determination unit 193 writes the determination result obtained in step S314 to the damage data storage unit 181 via the data management unit 191 (step S315). Specifically, when the repair policy determination unit 193 determines that the repair is necessary in step S314, the repair determination flag value of the corresponding line (the line whose damage type matches the target line) in the damage data is determined. The initial value “0” is rewritten to “1” indicating that repair is necessary. Furthermore, the repair policy determination unit 193 may display the determination result on the display unit 110.

Then, the repair policy determination unit 193 determines whether or not the processing of the loop L21 has been performed on all the rows of the damage comprehensive evaluation data stored in the damage comprehensive evaluation data storage unit 183, and branch processing is performed according to the determination result. Is performed (step S316). When it is determined that the processing of the loop L21 has been performed for all the rows, the loop L21 is terminated. On the other hand, if it is determined that there is a line that has not been processed yet, the process returns to step S311 to continue the processing of the loop L21 for the unprocessed line.
When the loop L21 is terminated in step S316, the process of FIG. 7 is terminated.

Returning to the process of FIG. 5, after step S151, the process of FIG.
On the other hand, when it is determined in step S113 that there is no line having the same damage type (step S113: NO), the repair policy determination unit 193 determines whether or not the target line needs repair (step S131).

FIG. 8 is a flowchart illustrating a processing procedure in which the repair policy determination unit 193 determines whether or not the target line in the loop L11 is repaired. The repair policy determination unit 193 performs the process of FIG. 8 in step S131 of FIG.
In the process of FIG. 8, the repair policy determination unit 193 first acquires a repair criterion corresponding to the target row (step S411). Specifically, the repair policy determination unit 193 acquires, via the data management unit 191, data of a row whose damage type matches the target row among the repair reference data stored in the repair reference data storage unit 182. .

Next, the repair policy determination unit 193 determines whether or not the repair is necessary by comparing the measured value of the target row or the calculated value from the measured value with the repair standard obtained in Step S411 (Step S412).
Specifically, the repair policy determination unit 193 compares the measurement value with the determination reference value for the determination reference value that directly corresponds to the measurement value such as length and width, and the measurement value is larger than the determination reference value. Therefore, it is determined that repair is necessary.

On the other hand, for the determination value (area (S) in the example of FIG. 3) corresponding to the value calculated from the measurement value, the repair policy determination unit 193 calculates the determination target value from the measurement value and determines the determination criterion. When the calculated value is larger than the determination reference value, it is determined that repair is necessary.
The repair policy determination unit 193 determines that the repair is necessary when the measured value or the calculated value from the measured value is larger than the determination reference value for any of the determination reference values. On the other hand, for all the determination reference values, when the measured value or the calculated value from the measurement value is equal to or less than the determination reference value, the repair policy determination unit 193 determines that the repair is unnecessary.

  In addition, about the value which is not measured at the time of an inspection, the damage data storage part 181 has memorize | stored the minimum value ("0" in the example of FIG. 2) as a measured value. On the other hand, the repair reference data storage unit 182 uses the maximum value (“999” for the length and “9999” for the area in the example of FIG. 3) for the determination reference value corresponding to the value that is not measured at the time of inspection. I remember it. Therefore, for a value that is not measured at the time of measurement, the measured value or the calculated value from the measured value is equal to or less than the determination reference value.

After step S412, the repair policy determination unit 193 writes the determination result obtained in step S412 to the damage data storage unit 181 via the data management unit 191 (step S413). Specifically, when the repair policy determination unit 193 determines that the repair is necessary in step S412, the repair determination flag value of the target line of the damage data needs to be repaired from the initial value “0”. Rewrite it to “1” to indicate this. Furthermore, the repair policy determination unit 193 may display the determination result on the display unit 110.
After step S413, the process of FIG. 8 ends.
Further, returning to the processing of FIG. 5, after step S131, the process proceeds to step S141.

As described above, the comprehensive evaluation value calculation unit 192 calculates the comprehensive evaluation value obtained by comprehensively evaluating the measured values of damage having the same damage type in the damage data. Then, the repair policy determination unit 193 determines the repair policy by comparing the comprehensive evaluation value calculated by the comprehensive evaluation value calculation unit 192 with the repair reference data.
Thereby, the repair policy determination unit 193 can determine a repair policy by comprehensively evaluating a plurality of damages. In this regard, the repair work support device 100 (the repair policy determination unit 193) can deal with various situations as well as presenting a repair policy based on the data for each damaged part, and has a more appropriate repair policy. Can be presented.

The repair standard data storage unit 182 stores repair standard data in which a region and a damage type are associated with each other as a damage type. And the data management part 191 acquires the damage data which matched the area | region and the kind of damage as a kind of damage.
As described above, the repair standard data storage unit 182 stores the repair standard data in which the area and the damage type are associated as the damage type, so that the setter of the repair standard data organizes the repair standard data. It is possible to grasp and it is relatively easy to set and update repair standard data.

  In general, there may be a plurality of types of damage (damage forms) in one region, for example, there is a defect other than a crack as damage to the plug. In such a case, if the damage type is not composed of an area and a damage type, it is difficult for the person who sets the repair reference data to know what type of damage is defined for each area. As a result, there is a risk that the setting of repair reference values may be missed, or a plurality of repair reference values may be set for the same damage type, resulting in inconsistencies.

On the other hand, the repair standard data storage unit 182 stores repair standard data in which a region and a damage type are associated with each other as a damage type. It is relatively easy to see if the type of damage is specified. As a result, it is possible to reduce the possibility that the setting of the repair reference value may be omitted or that a plurality of repair reference values may be set for the same damage type to cause a contradiction.
Furthermore, the repair reference data can be systematized and given a degree of freedom, such as setting the area more finely.

Further, the comprehensive evaluation value calculation unit 192 comprehensively evaluates values calculated from the measurement values to calculate a comprehensive evaluation value. For example, the comprehensive evaluation value calculation unit 192 calculates an area of damage from the length and width of damage, and calculates an overall evaluation value of a plurality of damage areas.
Thereby, the repair policy determination unit 193 can determine the repair policy by performing comprehensive evaluation not only on the measurement values stored in the damage data storage unit 181 but also on the values calculated from the measurement values. In this respect, the repair work support apparatus 100 (the repair policy determination unit 193) can cope with more various situations and present a more appropriate repair measure policy.

Note that the representation format of data stored in the storage unit 180 is not limited to the above-described format, and may be various formats. For example, the storage unit 180 may store data obtained by integrating the repair reference data and the damage comprehensive evaluation data in place of the repair reference data and the damage comprehensive evaluation data.
In addition, you may make it the damage data storage part 181 memorize | store further operation time as a measured value. For example, the control unit 190 may rewrite the determination reference value according to the operation time or the operation time of the gas turbine until the next regular inspection.

<First Modification>
The data stored in the storage unit 180 and the comprehensive evaluation value calculated by the comprehensive evaluation value calculation unit 192 are not limited to the above example and can be various. In the following, other examples of the data stored in the storage unit 180 and the comprehensive evaluation value calculated by the comprehensive evaluation value calculation unit 192 will be described in a modification of the present embodiment.
The functional configuration of the repair work support device in each modification is the same as that in FIG. 1 and will be described below with reference to FIG.

FIG. 9 is an explanatory diagram showing an example of damage comprehensive evaluation data stored in the damage comprehensive evaluation data storage unit 183 in the first modification of the present embodiment. In this figure, the damage comprehensive evaluation data is shown in a table format, and one line corresponds to one comprehensive evaluation value. Each row of data includes a “No.” column, a “repair reference table record No.” column, a “type” column, and a “calculated value” column.
The “No.” column, the “repair standard table record No.” column, and the “calculated value” column are the same as described with reference to FIG.

The “type” column is an attribute of the determination reference value to be subjected to comprehensive evaluation (in the example of FIG. 3, any of length (L), width (W), depth (D), area (S), and number of damages). Stores the type that indicates).
The comprehensive evaluation value calculation unit 192 updates the calculated value based on the attribute indicated by the type. Specifically, the comprehensive evaluation value calculation unit 192 adds the value corresponding to the attribute indicated by the type to the calculated value in the process of step S213 in FIG.

For example, when the type is length (L), the comprehensive evaluation value calculation unit 192 adds the calculated value and the measured value of the damage length.
When the type is area (S) and the diameter (φ) in the measurement value is 0, the comprehensive evaluation value calculation unit 192 multiplies the length (L) and the width (W) in the measurement value. Calculate the area of damage and add the calculated value and the area obtained.

In addition, when the type is area (S) and the diameter (φ) in the measurement value is not 0, the comprehensive evaluation value calculation unit 192 squares the half of the diameter and multiplies the circumference to calculate the area of damage. Calculate and add the calculated value and the area obtained.
When the type is the number of damages, the comprehensive evaluation value calculation unit 192 adds 1 to the calculated value.
Further, in step S314 in FIG. 7, the repair policy determination unit 193 determines whether or not repair is necessary by comparing the calculated value with the determination standard value of the attribute indicated by the type among the repair standards obtained in step S313. To do.

  As described above, the damage comprehensive evaluation data storage unit 183 has the evaluation target data (corresponding to the damage type indicated by the repair reference table record No.) and the damage evaluation target (the attribute indicated by the type). The repair criteria table record No. and the type) of the damage comprehensive evaluation data are stored. Then, the comprehensive evaluation value calculation unit 192 comprehensively evaluates the damage measurement values in the data corresponding to the damage type and the damage evaluation target indicated by the evaluation target data from the damage data acquired by the data management unit 191 and performs a comprehensive evaluation. An evaluation value is calculated.

In this way, by clearly specifying the attributes to be comprehensively evaluated, the repair policy determination unit 193 can more reliably determine the necessity of repair in accordance with the determination criteria intended by the user. Can be further enhanced.
In addition, the repair policy determination unit 193 can perform comprehensive evaluation on each of a plurality of determination reference values included in the same row of the repair reference data. In this respect, the repair work support apparatus 100 (the repair policy determination unit 193) can cope with more various situations and present a more appropriate repair measure policy.

<Second Modification>
FIG. 10 is an explanatory diagram illustrating an example of damage comprehensive evaluation data stored in the damage comprehensive evaluation data storage unit 183 in the second modification of the present embodiment. In this figure, the damage comprehensive evaluation data is shown in a table format, and one line corresponds to one comprehensive evaluation value. In addition, the data of each row includes a “No.” column, a “repair reference table record No.” column, a “type” column, a “weight A” column to a “weight D” column, and a “distance threshold A” column. To “Distance threshold C” column and “Calculated value” column.
The “No.” column, the “repair standard table record No.” column, and the “calculated value” column are the same as described with reference to FIG. The “type” column is the same as that described with reference to FIG.

  The “weight A” column to the “weight D” column store the weight A to the weight D, respectively. The weights A to D are weights for the measured value or the value calculated from the measured value when the comprehensive evaluation value calculation unit 192 calculates the comprehensive evaluation value. For the weights A to D, a constraint condition of weight A ≧ weight B ≧ weight C ≧ weight D is provided.

  The “distance threshold A” column to the “distance threshold C” column store the distance threshold A to the distance threshold C, respectively. The distance threshold A to the distance threshold C are thresholds for switching the weight used by the comprehensive evaluation value calculation unit 192 among the weights A to D. The distance threshold A to the distance threshold C are provided with a constraint condition of distance threshold A ≦ distance threshold B ≦ distance threshold C.

FIG. 11 is a flowchart illustrating a processing procedure in which the comprehensive evaluation value calculation unit 192 performs weighting on a measured value or a value calculated from the measured value. The comprehensive evaluation value calculation unit 192 performs the process of FIG. 11 in step S213 of FIG.
In the process of FIG. 11, the comprehensive evaluation value calculation unit 192 first calculates the distance of the target row of the loop L11 in the damage data (the distance to the nearest other damage stored in the “distance” column) as the distance. It is determined whether or not it is larger than the threshold value C (step S511).

When it is determined that the distance of the target row is larger than the distance threshold C (step S511: YES), the comprehensive evaluation value calculation unit 192 performs weighted addition with the weight D to the measurement value or a value calculated from the measurement value. Is performed (step S512). Specifically, the comprehensive evaluation value calculation unit 192 multiplies the measured value obtained in step S212 or a value calculated from the measured value by the weight D, and adds the calculated value obtained in step S211.
After step S512, the process in FIG. 11 is terminated.

On the other hand, when it is determined in step S511 that the distance of the target row is equal to or smaller than the distance threshold C (step S511: NO), the comprehensive evaluation value calculation unit 192 determines whether the distance of the target row is larger than the distance threshold B. Is determined (step S521).
When it is determined that the distance of the target row is larger than the distance threshold B (step S521: YES), the comprehensive evaluation value calculation unit 192 performs weighted addition with the weight C to the measurement value or a value calculated from the measurement value. Is performed (step S522). Specifically, the comprehensive evaluation value calculation unit 192 multiplies the measured value obtained in step S212 or a value calculated from the measured value by the weight C, and adds the calculated value obtained in step S211.
After step S522, the process of FIG. 11 is terminated.

On the other hand, when it is determined in step S521 that the distance of the target row is equal to or smaller than the distance threshold B (step S521: NO), the comprehensive evaluation value calculation unit 192 determines whether the distance of the target row is larger than the distance threshold A. Is determined (step S531).
When it is determined that the distance of the target row is greater than the distance threshold A (step S531: YES), the comprehensive evaluation value calculation unit 192 performs weighted addition with the weight B to the measurement value or the value calculated from the measurement value. Is performed (step S532). Specifically, the comprehensive evaluation value calculation unit 192 multiplies the measurement value obtained in step S212 or the value calculated from the measurement value by the weight B, and adds the calculated value obtained in step S211.
After step S532, the process in FIG. 11 is terminated.

On the other hand, when it is determined in step S531 that the distance of the target row is equal to or smaller than the distance threshold A (step S531: NO), the comprehensive evaluation value calculation unit 192 determines the measured value or a value calculated from the measured value. , Weighting addition by weight A is performed (step S541). Specifically, the comprehensive evaluation value calculation unit 192 multiplies the measured value obtained in step S212 or a value calculated from the measured value by the weight A, and adds the calculated value obtained in step S211.
After step S541, the process of FIG. 11 is terminated.

  As described above, the comprehensive evaluation value calculation unit 192 performs the weighted sum of the measurement value or the value calculated from the measurement value as the comprehensive evaluation of the measurement value. For example, in FIG. In the case of the row 1, the total evaluation value calculation unit 192 multiplies the crack length of the chip near the other damage by a relatively large weight with respect to the crack of the chip. On the other hand, for a crack located far from other damages, the length of the crack is multiplied by a relatively small weight.

For example, when a plurality of damages are located near each other, such as when cracks are arranged vertically, it is conceivable that the progress of damage is accelerated due to a synergistic effect between the damages. Therefore, the comprehensive evaluation value calculation unit 192 multiplies the length of a crack located near other damage by a relatively large weight to cope with the speed of damage progress due to the synergistic effect between the damages. Can do.
In this way, the comprehensive evaluation value calculation unit 192 performs the weighted sum of the measurement values or the values calculated from the measurement values, so that the repair work support device 100 (the repair policy determination unit 193) can cope with the synergistic effect between the damages. can do. In this respect, the repair work support apparatus 100 (the repair policy determination unit 193) can cope with more various situations and present a more appropriate repair measure policy.

<Third Modification>
In the third modification example of the present embodiment, the storage unit 180 further stores area integration evaluation data. The area integration evaluation data is data indicating areas to be integrated when determining whether or not the damage data stored in the damage data storage unit 181 is repaired.
FIG. 12 is an explanatory diagram illustrating an example of region integration evaluation data stored in the storage unit 180 in the present modification. In the figure, the area integration evaluation data is shown in a table format, and one line corresponds to one area. The data in each row includes a “No.” column, a “damage type” column, an “region” column, and an “integrated region” column.

The “No.” column stores identification information (for example, serial number) for each row of the area integration evaluation data.
The “type of damage” column stores the type of damage. The type of damage stored in the “damage type” column corresponds to the type of damage stored in the “damage type” column of the damage data.
The “area” column stores an area. The region stored in the “region” column corresponds to the region (region including damage) stored in the “region” column of damage data.
The “integrated area” column stores the area after the area integration.

FIG. 13 is an explanatory diagram illustrating a processing procedure in which the control unit 190 performs region integration. The control unit 190 performs the process of FIG. 13 as a preprocess for determining whether or not repair is necessary (for example, the preprocess of the process of FIG. 5).
In the processing of FIG. 13, the control unit 190 first starts a loop L31 that performs processing for each row of area integration evaluation data stored in the storage unit 180 (step S611).
Next, the control unit 190 (data management unit 191) acquires the data of the target row of the region integration evaluation data (step S612).

Then, the control unit 190 starts a loop L32 that performs processing for each row of damage data stored in the damage data storage unit 181 (step S621).
Next, the control unit 190 (data management unit 191) acquires data of a target row of damage data (step S622).

Then, the control unit 190 determines whether or not the damage type and area of the target row of the area integration evaluation data acquired in step S612 matches the damage type and area of the target line of the damage data acquired in step S622. Determination is made (step S623).
When it is determined that they match (step S623: YES), the control unit 190 (data management unit 191) sets the value of the “integrated region” of the target row of the region integration evaluation data in the “region” column of the target row of damage data. Writing is performed (step S624).

  Next, the control unit 190 determines whether or not the processing of the loop L32 has been performed on all the rows of damage data stored in the damage data storage unit 181 and performs branch processing according to the determination result (step S625). ). If it is determined that the processing of the loop L32 has been performed for all the rows, the loop L32 is terminated. On the other hand, if it is determined that there is a line that has not been processed yet, the process returns to step S621, and the process of the loop L32 is continued for the unprocessed line.

When the loop L32 ends in step S625, the control unit 190 determines whether or not the processing of the loop L31 has been performed on all the rows of the area integration evaluation data stored in the storage unit 180, and branches according to the determination result. Processing is performed (step S631). When it is determined that the processing of the loop L31 has been performed for all the rows, the loop L31 is terminated. On the other hand, if it is determined that there is a line that has not been processed yet, the process returns to step S611, and the process of the loop L31 is continued for the unprocessed line.
When the loop L31 is terminated in step S631, the process of FIG. 13 is terminated.
On the other hand, if it is determined in step S623 that the damage type and area of the target row of the area integration evaluation data do not match the damage type and area of the target line of the damage data (step S623: NO), the process proceeds to step S625. .

  For example, in the case of FIG. 12, the control unit 190 includes a row of the damage data in which the type of damage is “coating peeling” and the region is “region A”, “region B”, or “region C” (in FIG. 2). In the example, the values in the area columns of Nos. 11 to 13 are all replaced with “area X”. Thereby, the control unit 190 integrates the areas A to C with the area X.

As described above, the control unit 190 performs region integration, so that the repair policy determination unit 193 can comprehensively evaluate the measured values of each damage having the same damage type for the region obtained by integrating a plurality of regions.
FIG. 14 is an explanatory diagram illustrating an example of damage comprehensive evaluation data stored in the damage comprehensive evaluation data storage unit 183 in the present modification. In the example of FIG. No. 2 repair criteria table record No. The value of is 7.

As a result, the comprehensive evaluation value calculation unit 192 has the repair reference data No. 1 in the damage data storage unit 181. The comprehensive evaluation value is calculated based on the measurement value of the row corresponding to the damage type “coating peeling” and the region “blade surface X” in the seventh row. And the repair policy determination part 193 evaluates damage comprehensively based on the said comprehensive evaluation value, and determines the necessity of repair.
Specifically, as described above, the No. of damage data in FIG. The value of the area column of the 11th to 13th rows is “area X”, and the comprehensive evaluation value calculating unit 192 calculates the total value of the damage areas according to the measurement values of these lines. Then, the repair policy determination unit 193 determines whether or not the repair is necessary by comparing the total area value calculated by the comprehensive evaluation value calculation unit 192 with the determination reference value.

As described above, the repair policy determination unit 193 comprehensively evaluates the measured values of each damage having the same damage type for the area obtained by integrating a plurality of areas.
Thereby, the repair policy determination unit 193 can determine a repair policy by comprehensively evaluating damages included in a plurality of areas. In this regard, the repair work support device 100 (the repair policy determination unit 193) can deal with various situations as well as presenting a repair policy based on the data for each damaged part, and has a more appropriate repair policy. Can be presented.

<Fourth Modification>

In the figure, the area integration evaluation data is shown in a table format, and one line corresponds to one area. Each row of data includes a “No.” column, a “damage type” column, an “region” column, a “weight” column, and an “integrated region” column.

The “No.” column, “damage type” column, “region” column, and “integrated region” column are the same as described with reference to FIG.
The “weight” column stores the weight for measurement data or data calculated from the measurement data.

The comprehensive evaluation value calculation unit 192 refers to the region integration evaluation data when adding the calculated value and the measured value or the value calculated from the measured value in step S213 of FIG. If there is a corresponding row, the comprehensive evaluation value calculation unit 192 multiplies the weight of the corresponding row by the measured value or a value calculated from the measured value, and then calculates the calculated value and the measured value after the weight multiplication or the measured value. Add the value calculated from.
In order to enable the comprehensive evaluation value calculation unit 192 to perform the process, the control unit 190 does not delete the region of the target line of damage data (the value in the “region” column) in step S624 in FIG. It is written together with the area.

  In the case of the example of FIG. The area calculated from the measured values in 11 rows is multiplied by 4 and then added to the calculated value. Further, the comprehensive evaluation value calculation unit 192 displays the No. 1 in FIG. The area calculated from the measured values in 12 rows is multiplied by 3, and then added to the calculated value. Further, the comprehensive evaluation value calculation unit 192 displays the No. 1 in FIG. The area calculated from the measured values in 11 rows is multiplied by 2 and then added to the calculated value. On the other hand, the comprehensive evaluation value calculation unit 192 displays the No. 1 in FIG. The area calculated from the measured values in 13 rows is multiplied by 1 (therefore, the calculated area is maintained) and added to the calculated value.

As described above, the comprehensive evaluation value calculation unit 192 performs the weighted sum for each region of the measurement value or the value calculated from the measurement value as the comprehensive evaluation of the measurement value.
Thereby, even when the degree of damage influence varies from region to region, the repair policy determination unit 193 can determine the necessity of repair by reflecting the degree of damage influence for each region. In this respect, the repair work support apparatus 100 (the repair policy determination unit 193) can cope with more various situations and present a more appropriate repair measure policy.
