<First Embodiment>
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a schematic configuration diagram showing a device configuration of an inspection support system according to the first embodiment of the present invention. In FIG. 1, the inspection support system 1 includes an inspection terminal device 100 and an inspection support device 200.

The inspection support system 1 is a system that supports an inspection of an inspection target performed by an inspector.
Specifically, the inspection support system 1 determines the presence / absence of a non-conforming part in the inspection target based on the image to be inspected, and if a non-conforming part is found, determines the necessity of handling. When it is determined that a response is necessary, the inspection support system 1 presents a proposed response policy to the inspector. The inspector determines the response policy by referring to the response policy proposal presented by the inspection support system 1.

  The non-conformity here includes not only failures and abnormalities but also states where signs of failure or abnormalities are observed. The inspection support system 1 detects nonconformities that are accompanied by changes in the appearance such as deformation of the inspection target, cracks, thinning, adhesion of foreign substances, and clogging. Therefore, the inspection support system 1 can be applied to various facilities (plants or equipment) that may cause incompatibility accompanied by changes in appearance.

  For example, in the inspection of a gas turbine power plant, the main body and bearings at the inlet of the gas turbine, the rotor blades and rings of the compressor casing, the combustion / compression casing, the combustor section, the valves, shafts and rings of the bypass valve variable mechanism, turbine Body, ring and stator blades, exhaust casing body and bearings and plates, exhaust chamber body, ducts and supports, rotor bolts and disks, The inspection support system 1 can be used for inspection of machines and the like. Further, for example, in the inspection of the compressor casing of the gas turbine power plant, the inspection support system 1 can be used to determine a countermeasure policy for various nonconformities such as deformation of blades and rings, dents and coating peeling.

  In addition, the correspondence here includes replacement and repair. The inspection support system 1 presents whether or not replacement of a part is recommended as a countermeasure policy proposal, and a repair policy candidate (such as a repair method candidate) in the case of repair. The parts here are units for replacement. For example, when replacement is performed in units of equipment in the plant, the equipment corresponds to an example of a part here.

The inspection terminal device 100 is a portable terminal device, and an inspector uses the inspection terminal device 100 at an inspection site where an inspection object is installed. The inspection terminal device 100 captures an inspection target and transmits the captured image to the inspection support device 200 in accordance with the operation of the inspector.
Here, the inspection terminal device 100 may pick up an image of the entire inspection object, or may pick up an image of each part of the inspection object. In particular, when the inspection target is large, such as when the inspection target is a plant, the inspection terminal device 100 captures an image for each part to be inspected, thereby obtaining an image with higher resolution.
Further, the inspection terminal device 100 displays the determination result of the necessity of response determined by the inspection support device 200 based on the captured image to be inspected and the response policy proposal.

The inspection support apparatus 200 first detects a non-conforming part based on the inspection target captured image captured by the inspection terminal apparatus 100. Specifically, the inspection support apparatus 200 determines the presence or absence of a non-conforming part based on the captured image from the inspection terminal device 100, and if there is a non-conforming part, specifies the position thereof.
When it is determined that there is a non-conforming part, the inspection support apparatus 200 determines whether or not it is necessary to deal with the non-conforming part, and when it is determined that a countermeasure is necessary, a countermeasure policy draft is further generated and transmitted to the inspection terminal device 100. Display.
The inspection support device 200 is configured by a computer, for example.

  FIG. 2 is a schematic block diagram illustrating a functional configuration of the inspection support system 1. As described with reference to FIG. 1, the inspection support system 1 includes the inspection terminal device 100 and the inspection support device 200.

In the inspection terminal device 100, the imaging unit 110 has an imaging element and performs imaging. In particular, the imaging unit 110 captures an image to be inspected.
The display unit 120 includes a display screen such as a liquid crystal panel or an organic EL (Organic Electro-Luminescence) panel, and displays various images such as a moving image, a still image, and text (characters). In particular, the display unit 120 displays a repair policy candidate that the communication unit 170 acquires (receives) from the inspection support device 200, a determination result as to whether or not to recommend replacement, and the like.

The operation input unit 130 includes an input device such as a touch sensor (touch panel) provided on the display screen of the display unit 120, for example, and accepts user operations.
The communication unit 170 communicates wirelessly with the communication unit 270 of the inspection support apparatus 200, and transmits and receives various data. In particular, the communication unit 170 transmits an inspection target image captured by the imaging unit 110 to the inspection support apparatus 200 as image data. In addition, the communication unit 170 receives a repair policy candidate, a determination result on whether or not to recommend replacement of parts, and the like transmitted by the communication unit 270.
The communication unit 170 corresponds to an example of an image output unit and a determination result acquisition unit.

The storage unit 180 stores various data. The storage unit 180 is realized by a storage device included in the inspection terminal device 100.
The control unit 190 controls each unit of the inspection terminal device 100 to execute various functions. The control unit 190 is realized by, for example, a CPU (Central Processing Unit) included in the inspection terminal device 100 reading and executing a program stored in the storage unit 180.

In the inspection support device 200, the communication unit 270 communicates wirelessly with the communication unit 170 of the inspection terminal device 100 to transmit and receive various data. In particular, the communication unit 270 receives an image to be inspected from the inspection terminal device 100. The inspection support device 200 also displays the repair policy candidate generated by the control unit 290 based on the image to be inspected from the inspection terminal device 100, the determination result as to whether or not to recommend replacement of parts, etc. Transmit to device 100.
The communication unit 270 corresponds to an example of an image acquisition unit and a determination result output unit.

The storage unit 280 stores various data. The storage unit 280 is realized by a storage device included in the inspection support apparatus 200.
The response history storage unit 281 stores a response history for nonconformity. In particular, the correspondence history storage unit 281 stores a repair history such as a repair method when repairing a non-conforming part. The response history storage unit 281 may store the response history of the inspection target, or may store the response history of one or more facilities similar to the inspection target (hereinafter referred to as “similar facilities”). You may make it memorize | store both.
The correspondence history storage unit 281 corresponds to an example of a repair history storage unit.

The control unit 290 controls each unit of the inspection support apparatus 200 and executes various functions. The control unit 290 is realized by, for example, a CPU (Central Processing Unit) included in the inspection support device 200 reading and executing a program stored in the storage unit 280.
The nonconforming part detection unit 291 detects a nonconforming part from the image to be inspected. Specifically, the nonconforming part detection unit 291 divides the image to be inspected received by the communication unit 270 into predetermined areas, and performs pattern matching with the image template of the nonconforming part for each of the divided areas. Determine the presence or absence of a part.

FIG. 3 is an explanatory diagram illustrating an example of division of an image to be inspected performed by the nonconforming part detection unit 291. In the example shown in the figure, the nonconforming portion detection unit 291 divides the inspection target image into four regions A11 to A14. The nonconforming part detection unit 291 performs pattern matching with each of the regions A11 to A14 obtained by the division with the image template of the nonconforming part stored in the storage unit 280 in advance. The storage unit 280 stores image templates of nonconforming parts for each region of the image to be inspected and for each type of nonconformity such as deformation, cracking, thinning, adhesion of foreign matter, and clogging. The unit 291 performs pattern matching for each type of nonconformity.
The nonconforming part detection unit 291 calculates the similarity between the image of the region obtained by dividing the image to be inspected by pattern matching (hereinafter referred to as “divided region image”) and the image template, and is similar for one or more types of nonconformity. A region having a degree equal to or greater than a predetermined determination threshold is determined as a region having a nonconforming portion.

  Here, various units can be used as a unit by which the nonconforming part detection unit 291 divides the image of the nonconforming part. For example, the non-conforming part detection unit 291 divides the image for each part (for each unit for replacement), thereby limiting the target for the replacement recommendation determination unit 294 to determine whether or not to recommend replacement. And the processing load of the replacement recommendation determination unit 294 can be reduced.

The pattern matching performed by the nonconforming part detection unit 291 is not limited as long as it can determine the similarity between the region of the image to be inspected and the image template of the nonconforming part, and various pattern matching methods can be used.
In addition, the nonconforming part detection unit 291 is different for each region of the image to be inspected, such as using a different determination threshold for each region of the image to be inspected, or using a different pattern matching method for each region of the image to be inspected. A determination criterion may be used.

The correspondence necessity determination unit 292 determines whether it is necessary to cope with the nonconforming part based on a predetermined evaluation criterion.
Specifically, the correspondence necessity determination unit 292 first acquires the position information of the nonconforming part for the region determined by the nonconforming part detection unit 291 to be the nonconforming part. For example, when the non-conforming part detection unit 291 performs pattern matching, the coordinates of the non-conforming part are calculated, and the correspondence necessity determination unit 292 acquires the coordinates.

Next, the necessity determination unit 292 determines necessity of correspondence by evaluating the detected nonconforming portion based on an evaluation criterion set in advance for each region of the image to be inspected. For example, when the type of nonconformity is a crack, the nonconforming part detection unit 291 detects the length of the crack, and compares the crack length threshold set in advance as an evaluation criterion with the detected crack length. If the length of the detected crack is longer than the threshold, it is determined that it is necessary to deal with it. On the other hand, when the length of the detected crack is less than the threshold, the nonconforming portion detection unit 291 determines that no correspondence is required.
Further, in a region where it is determined that a countermeasure is required if there is a crack, the countermeasure necessity determination unit 292 determines the necessity of the countermeasure depending on the presence or absence of a crack.

The repair policy candidate search unit 293 searches for a repair policy candidate from the repair history stored in the response history storage unit 281 based on the image of the nonconforming portion when the response necessity determination unit 292 determines that the response is necessary.
Specifically, the correspondence history storage unit 281 responds as a correspondence history for nonconformity, such as a divided area image including a nonconforming portion, whether replacement or repair has been performed, and repair history (such as a repair method) in the case of repair. The contents are stored in association with each other.

Then, the repair policy candidate search unit 293 includes, in the correspondence history stored in the correspondence history storage unit 281, the correspondence history of the region corresponding to the region determined to be necessary by the correspondence necessity determination unit 292 and the repair history. To extract the response history.
Here, the area corresponding to the area determined to be required by the response necessity determination unit 292 is the necessity of the response necessity determination unit 292 such as the same location in the same facility or similar facility, or the location of the same part. The determined area is a similar area to the possible nonconformity. For example, if the response necessity determination unit 292 determines that it is necessary to cope with the compressor blade region in the gas turbine power plant, the repair policy candidate search unit 293 sets the region of the compressor blade of the same type or a similar type as the corresponding region. , Extraction of correspondence history.

  Then, the repair policy candidate search unit 293 performs pattern matching between the nonconforming portion in the image of the area determined to be necessary by the correspondence necessity determining unit 292 and the nonconforming portion in the divided region image included in the correspondence history, thereby Extract correspondence history with similar parts. That is, the repair policy candidate search unit 293 searches for a repair policy candidate from the repair history using the divided region image as a search key.

FIG. 4 is an explanatory diagram illustrating an example of a divided region image used by the repair policy candidate search unit 293 for pattern matching. In the figure, a region A21 indicates a divided region image obtained by dividing the inspection target image, and a region A22 indicates a divided region image included in the correspondence history.
The repair policy candidate search unit 293 calculates the degree of similarity by performing pattern matching between the image of the nonconforming part in the region A21 and the image of the nonconforming part in the region A22. Then, the repair policy candidate search unit 293 compares the obtained similarity with a threshold of similarity set in advance as a similarity determination criterion. When the obtained similarity is equal to or greater than the threshold value, the repair policy candidate search unit 293 acquires the repair history associated with the image of the area A22 in the correspondence history as a repair policy candidate.

The pattern matching performed by the repair policy candidate search unit 293 only needs to be able to determine the similarity between the nonconforming part in the inspection target and the nonconforming part in the correspondence history, and various pattern matching methods can be used.
Further, the repair policy candidate search unit 293 may use different criteria (for example, whether to consider or ignore the crack direction) for each region of the image to be inspected.

When there are a plurality of correspondence histories that are similar to the non-conforming portions, the repair policy candidate search unit 293 acquires all the corresponding repair histories as repair policy candidates. Alternatively, the repair policy candidate search unit 293 may acquire a predetermined upper number of repair histories as repair policy candidates in the order in which the nonconforming parts are similar.
On the other hand, when there is no correspondence history in which the nonconforming parts are similar, the repair policy candidate search unit 293 determines that there is no repair policy candidate. Or you may make it the repair policy candidate search part 293 acquire the repair log | history most similar of a nonconforming part as a repair policy candidate.

The replacement recommendation determination unit 294 obtains a failure occurrence rate at which a component having a non-conforming part generates a failure such as a device failure or malfunction until the next inspection, and compares the non-conforming part with a threshold value. It is determined whether or not it is recommended to replace a part having
Specifically, the storage unit 280 stores in advance a relationship between an operation time (here, an operation time of a device including the component) and a failure occurrence rate for each component. The relationship between the operation time and the failure occurrence rate can be obtained from, for example, the operation results of parts of the same type. Alternatively, the relationship between the operation time and the failure occurrence rate may be obtained by simulation.

  Then, the replacement recommendation determination unit 294 calculates (predicts) the operation time of the device at the next inspection. For example, the replacement recommendation determination unit 294 obtains the operation rate (operation time per unit time) of the inspection target from the operation mode of the inspection target, and calculates the operation rate in the time from the use start time for each part to the next regular inspection. Multiply to calculate the operating time of the equipment at the next inspection. The operation mode here refers to the inspection target such as continuous operation (BL; Base Load), daily operation (DSS; Daily Start And Stop) or weekly operation (WSS; Weekly Start And Stop) in the gas turbine power plant. This mode determines the start / stop pattern. Further, the use start time for each component is stored in the storage unit 280 as a component replacement history (part of maintenance history), for example.

Alternatively, the replacement recommendation determination unit 294 may calculate the operation time of the device at the next inspection using information other than the operation mode, such as obtaining the operation rate in the past operation performance to be inspected.
In addition, when the past operation results of the inspection target can be obtained, the actual operation time is calculated for the operation time from the start of use of the part to the present (at the time of this inspection), not the estimated time based on the operation rate. You may do it.

Next, the replacement recommendation determination unit 294 applies the obtained operation time to the relationship between the operation time stored in the storage unit 280 and the failure occurrence rate, and acquires the failure occurrence rate at the next inspection.
Then, the replacement recommendation determination unit 294 compares the obtained failure occurrence rate with a failure occurrence rate threshold set in advance as a replacement recommendation presence / absence determination criterion. When the obtained failure occurrence rate is equal to or higher than the threshold value, the replacement recommendation determination unit 294 determines to recommend replacement. On the other hand, when the obtained failure occurrence rate is less than the threshold value, the replacement recommendation determination unit 294 determines not to recommend replacement.

  FIG. 5 is an explanatory diagram illustrating an example of determination as to whether or not replacement is recommended performed by the replacement recommendation determination unit 294. In the figure, the horizontal axis indicates the operation time, and the vertical axis indicates the failure occurrence rate of the device. Time T31 indicates the current operation time (at the time of the current inspection), and time T32 indicates the expected operation time at the next inspection. A line L31 indicates the relationship between the operation time stored in the storage unit 280 and the failure occurrence rate. Further, the value V31 indicates a failure rate threshold, and the value V32 indicates a failure rate at the next inspection (time T32).

In the example of FIG. 5, since the value V32 indicating the failure occurrence rate at the next inspection is equal to or greater than the threshold value V31, the replacement recommendation determination unit 294 determines to recommend replacement.
In addition, the replacement recommendation determination unit 294 can determine whether or not there is a replacement recommendation based on various indexes indicating the operation level of the inspection target, not limited to the operation time. For example, the replacement recommendation determination unit 294 may determine whether or not there is a replacement recommendation based on the number of times the inspection target is activated.

Next, with reference to FIG. 6 and FIG. 7, an example of a countermeasure policy proposed by the inspection support system 1 will be described.
FIG. 6 is an explanatory diagram illustrating an example of a query result list displayed by the display unit 120. This inquiry result list shows a list of nonconformities that the response necessity determination unit 292 determines to be required.
In the example of FIG. 6, the display unit 120 displays the query result list in a table format, and each row is captured by a component that needs to be handled (a divided area image that the handling necessity determining unit 292 has determined to need to handle). Parts).

The “No.” column in the table of FIG. 6 indicates a serial number in the query result list.
The “Serial No.” column indicates a serial number assigned to a component that needs to be handled. When the imaging unit 110 captures an image of a label describing the serial number, the control unit 290 (for example, the nonconforming part detection unit 291) extracts the serial number from the image. Alternatively, the operation input unit 130 may accept a serial number input operation by an inspector.

The “part name” field and the “part name” field respectively indicate the name of the part to which the part that needs to correspond and the name of the part. The “nonconformity” column indicates the type of nonconformity.
The “number of measure proposals” column indicates the number of measures proposed by the inspection support system 1. Specifically, when the replacement is not recommended, the inspection support system 1 uses the number of repair methods in the repair policy candidate acquired by the repair policy candidate search unit 293 (the number of overlapping repair methods is counted as one) as the number of action proposals. . On the other hand, when the replacement is recommended, the inspection support system 1 uses the number of repair methods in the repair policy candidate acquired by the repair policy candidate search unit 293 as 1 as the number of measure proposals.

The “number of past records” column indicates the number of repair policy candidates acquired by the repair policy candidate search unit 293 (even if the repair method is the same).
The “Replacement recommendation” column indicates whether or not replacement of a part is recommended. The value “Yes” in the column indicates that replacement is recommended, and “None” indicates that replacement is not recommended.
In the “Details” column, an “Open” button for referring to detailed information of the proposed response policy is displayed. When the operation input unit 130 detects a touch operation on the “Open” button, the display unit 120 displays detailed information on the selected response policy plan (response policy plan corresponding to the touched line).

FIG. 7 is an explanatory diagram illustrating an example of detailed information on a proposed response policy displayed by the display unit 120. In the example of the figure, an inquiry part area A41 is an area indicating information on parts that need to be handled.
The “Serial No.” column, “Part Name” column, and “Part Name” column in the inquiry area A41 are all the same as those in the inquiry result list (FIG. 6).
The “damage event” column indicates the type of nonconformity, as does the “nonconformity” column in the query result list. The “result” column indicates the determination result of the necessity determination unit 292 for handling. The value “pass” in the “result” column indicates the determination result that the response is not required, and the value “fail” indicates the determination result that the response is required.

  In addition, the response policy proposal area A42 is an area indicating a response policy proposal proposed by the inspection support system 1. Specifically, the display unit 120 displays “replacement” in the case where parts replacement is recommended as a countermeasure policy proposal, or a repair method in the repair policy candidate acquired by the repair policy candidate search unit 293 (in the example of FIG. Welding repair "and" Blending ") are shown in the corresponding policy proposal area A42.

The inspection target image region A43 is a region for displaying a divided region image of the inspection target image captured by the imaging unit 110, the image name, and the file name of the image data. In the example of FIG. 7, there are three images of parts that are targets of detailed information display, and each image, name, and file name are displayed. The name of the image may be automatically assigned by the inspection support system 1 (for example, the nonconforming part detection unit 291) using a serial number or the like, or is displayed only when a user (for example, an inspector) gives it. You may do it.
Further, the registration button B41 is a button for storing the currently displayed response policy proposal in the storage unit 180. When the operation input unit 130 detects a touch operation on the registration button B41, the control unit 190 causes the storage unit 180 to store the currently displayed response policy.

The past inspection recording area A44 is an area for displaying detailed information of the repair policy candidate detected by the repair policy candidate search unit 293.
The “Previous” button and the “Next” button in the past inspection recording area A44 are buttons for switching repair policy candidates for displaying detailed information. When the operation input unit 130 detects a touch operation on the “Previous” button or the “Next” button, the control unit 190 switches a repair policy candidate for which the operation input unit 130 displays detailed information.

The “Serial No.” column indicates a serial number assigned to the repaired part. The “part name” column and the “part name” column indicate the name of the part to which the repaired part belongs and the name of the part, respectively.
The “damage event” column indicates the type of nonconformity in the repair history that is a repair policy candidate. The “result” column indicates a determination result of necessity of correspondence in the repair history. The value “pass” in the “result” column indicates the determination result that the response is not required, and the value “fail” indicates the determination result that the response is required.
The “Correspondence Policy” column indicates the content of the correspondence performed in the repair history (specifically, the repair method).

  The past image area A45 is an area for displaying the divided area image in the repair history, the image name, and the file name of the image data. In the example of FIG. 7, there are three corresponding images, and each image, name, and file name are displayed.

Next, the operation of the inspection support system 1 will be described with reference to FIGS. 8 and 9.
FIG. 8 is a sequence diagram illustrating an operation example of the inspection support system 1.
In the figure, first, the imaging unit 110 of the inspection terminal device 100 images the inspection object in accordance with the operation of the inspector, and also provides identification information (for example, the serial number described in FIGS. 6 and 7) of the inspection object. Obtain (sequence S101).
Then, communication unit 170 transmits the inspection target image captured by imaging unit 110 and the inspection target identification information to inspection support device 200 (sequence S102).

  In the inspection support apparatus 200, the communication unit 270 receives the image and identification information from the communication unit 170, and the control unit 290 evaluates the state of the inspection target based on the image (sequence S111). Specifically, as described above, the nonconforming part detection unit 291 divides the image to be inspected into predetermined regions, and determines whether or not there is a nonconforming part for each region divided image.

Then, the necessity determination unit 292 determines whether or not it is necessary to deal with each area determined by the nonconforming part detection unit 291 that there is a nonconforming part (sequence S112).
Next, the repair policy candidate search unit 293 searches for a repair policy candidate from the repair history stored in the response history storage unit 281 for each region determined to be required by the response necessity determination unit 292 (sequence S113).

In addition, the replacement recommendation determination unit 294 determines whether or not to recommend replacement of a part having a non-conforming part for each region determined to be compatible by the response necessity determination unit 292 (sequence S114).
Then, the communication unit 270 obtains the determination result of necessity of correspondence in the sequence S112, the repair policy candidate obtained in the sequence S113 for the area determined to be correspondence, and the judgment result of necessity of replacement in the sequence S114. Then, the data is transmitted to the inspection terminal device 100 (sequence S115).

  In the inspection terminal device 100, the communication unit 170 receives the determination result of necessity of response transmitted from the communication unit 270, and the repair policy candidate and the determination result of necessity of replacement for the area determined to be necessary. . Then, in accordance with the operation of the inspector, the control unit 190 causes the display unit 120 to display the determination result of necessity of response, the repair policy candidate and the determination result of necessity of replacement for the area determined to be necessary ( Sequence S121). Specifically, the control unit 190 causes the display unit 120 to display the inquiry result list described with reference to FIG. 6 and the detailed information on the proposed response policy described with reference to FIG.

  Then, the operation input unit 130 accepts a response presence / absence determination operation and a response policy determination operation (sequence S122). The correspondence presence / absence determination operation here is an operation for determining the presence / absence of correspondence to a non-conforming part, that is, an input operation of a determination result as to whether or not to actually deal with non-conformity. Also, the response policy decision operation is the input of the response policy adopted when it is decided to actually deal with the nonconformity, that is, the decision operation of the response policy when dealing with the nonconformity part. It is an operation.

In this manner, the inspection terminal device 100 acquires information on the countermeasures actually determined by the inspector for the nonconformity detected by the nonconforming portion detection unit 291 including whether or not to respond.
Then, the communication unit 170 transmits information on the presence / absence of the correspondence obtained in sequence S122 and information on the correspondence policy in the case of correspondence (the presence / absence or the correspondence policy determined by the inspector) to the inspection support apparatus 200. (Sequence S123).

In the inspection support apparatus 200, the communication unit 270 receives the information on the presence / absence of the response transmitted by the communication unit 170 and the information on the response policy when responding.
Then, control unit 290 generates a response history in the current inspection based on the information on the presence / absence of the response and information on the response policy when corresponding, and stores the response history in response history storage unit 281 (sequence S131).

FIG. 9 is a flowchart illustrating a processing procedure in which the inspection support apparatus 200 generates and transmits inspection support information. In the process of FIG. 9, first, the communication unit 270 acquires (receives) the inspection target image and identification information transmitted by the communication unit 170 (step S201). Step S201 corresponds to the sequence S102 in FIG.
Next, the control unit 290 evaluates the state of the inspection target based on the image obtained in step S201 (step S202). Specifically, as described above, the nonconforming part detection unit 291 divides the image to be inspected into predetermined regions, and determines whether or not there is a nonconforming part for each region divided image. Step S202 corresponds to the sequence S111 in FIG.

Next, the control unit 290 starts a loop L11 that performs processing for each region divided in step S202 (step S211).
Then, the necessity determination unit 292 determines whether or not it is necessary to deal with the area determined by the nonconforming part detection unit 291 that there is a nonconforming part (step S212). Step S212 corresponds to the sequence S112 in FIG.

If it is determined in step S212 that it is necessary to respond (step S212: YES), the repair policy candidate search unit 293 performs repair stored in the response history storage unit 281 for each area determined to be required by the response necessity determination unit 292. A repair policy candidate is searched from the history (step S213). Step S213 corresponds to the sequence S113 in FIG.
In addition, the replacement recommendation determination unit 294 determines whether or not to recommend replacement of a part having a non-conforming part for each region determined to be required by the response necessity determination unit 292 (step S214). Step S214 corresponds to the sequence S114 in FIG.

  Note that the order of processing in steps S213 and S214 is not limited to the order shown in FIG. For example, after the replacement recommendation determination unit 294 performs the process of step S214, the repair policy candidate search unit 293 may perform the process of step S213. Alternatively, the replacement recommendation determination unit 294 and the repair policy candidate search unit 293 may perform processing in parallel.

  After step S214, the control unit 290 determines whether or not the processing of the loop L11 has been performed for all the regions divided in step S202, and transitions according to the determination result (step S215). If it is determined that there is an area for which the process of the loop L11 has not been performed yet, the process returns to step S211 to perform the process of the loop L11 for the remaining area. On the other hand, when it is determined that the processing of the loop L11 has been performed for all regions, the loop L11 is terminated.

After the loop L11, the communication unit 270 transmits the inspection support information generated by the control unit 290 to the inspection terminal device 100 (step S221). Specifically, the communication unit 270 determines whether or not it is necessary to respond in step S202, and determines whether or not the repair policy candidate obtained in step S213 and the replacement policy candidate in step S214 for the area determined to be compatible. The result is transmitted to the inspection terminal device 100 as inspection support information. Step S221 corresponds to the sequence S115 in FIG.
After step S221, the process of FIG. 9 ends.
On the other hand, if it is determined in step S212 that no response is required (step S212: NO), the process proceeds to step S215.

  As described above, the nonconforming part detecting unit 291 detects a nonconforming part from the image to be inspected, and the correspondence necessity determining unit 292 determines the necessity of dealing with the nonconforming part based on a predetermined evaluation criterion. When the response necessity determination unit 292 determines that the response is necessary, the repair policy candidate search unit 293 searches for a repair policy candidate from the repair history, and the replacement recommendation determination unit 294 determines whether or not replacement is recommended. .

  The inspection terminal device 100 displays the determination result of necessity of response, the repair policy candidate, and the presence / absence of replacement recommendation, so that the inspector can determine the response policy while referring to these pieces of information. Specifically, referring to the information, the inspector decides whether or not to deal with the nonconformity, if so, replaces or repairs the parts, and determines the repair method when repairing. Can do. Thus, the inspection support system 1 can support the determination of the response policy in the inspection work.

  Here, inspectors generally (1) degree of nonconformity in the inspection target, (2) repair history of the inspection target, (3) operation results or operation mode of the inspection target, (4) next inspection schedule, (5) Determine the necessity of parts replacement and the repair method when repairing in consideration of parts replacement standards. Among these, (1) the degree of nonconformity in the inspection target can be obtained by the inspector investigating the inspection target.

However, (2) repair / replacement history of inspection object, (3) operation result or operation mode of inspection object, (4) next inspection schedule, (5) parts replacement criteria, even if the inspection object is investigated I can't get it. For example, since repair and replacement are performed for each part even in the same plant, (2) the repair history of the inspection target needs to be confirmed for each part. In addition, (3) the operation mode of the inspection object differs for each inspection object (for example, for each plant) depending on the application and the administrator's policy. (4) The next inspection schedule is also determined for each inspection object. (5) The replacement standards for parts differ from part to part or from part to part.
When such information is unknown, the inspector needs to wait for an answer by inquiring an engineer or the like, which is a factor that takes time for the inspection.

  On the other hand, if the inspection support system 1 is used, the inspector, when imaging the inspection object, etc., determines whether or not to cope with the nonconformity, whether or not replacement is recommended, and when repairing. Can get repair policy candidates. Therefore, the inspector should acquire information such as (2) repair / replacement history of the inspection object, (3) operation results or operation mode of the inspection object, (4) next inspection schedule, and (5) parts replacement criteria. At least the response policy can be determined. In this respect, the time required for inspection and the burden on the inspector can be reduced. In addition, it is possible to avoid the possibility that an appropriate response policy cannot be established, such as repairing a part to be replaced, due to an error in information when the inspector collects information.

The confirmation terminal device 300 includes a display unit 320, an operation input unit 330, a communication unit 370, a storage unit 380, and a control unit 390.
In FIG. 13, parts having the same functions corresponding to the parts in FIG. 11 are denoted by the same reference numerals (110, 120, 130, 170, 180, 270, 280-281, 291-294). Omitted.

The inspection terminal device 600 performs the same processing as the inspection terminal device 400 (FIG. 10). In addition, the inspection terminal device 600 generates an inspection result report according to the presence / absence of the response and the response policy determined by the inspector.
The form storage unit 681 stores a form of the inspection result report in advance.
The form acquisition unit 691 acquires the form of the inspection result report based on the necessity of the response determined by the inspector and the response policy.
The decision item input unit 692 inputs the necessity of the response and the response policy determined by the inspector in the form of the inspection result report acquired by the form acquisition unit 691. Further, when the confirmation terminal apparatus 300 transmits a correction instruction for the necessity of the response determined by the inspector and a correction instruction for the response policy, the determination item input unit 692 reflects the correction instruction in the inspection result report.

FIG. 14 is an explanatory diagram illustrating an example of an inspection list generated by the inspection terminal device 600. The inspection list is data attached to the first sheet of the inspection result report, and is used as a cover and table of contents of the inspection report.
The “inspection date” column of the inspection list in FIG. 14 indicates the date on which the inspector performed the inspection. The “inspection object” column indicates the name of the inspection object such as a plant name. The “Serial No.” column indicates the serial number assigned to the part to be inspected. The “judgment result” column shows the result of the judgment as to whether or not the part needs to be handled.

The form acquisition unit 691 acquires (reads out) the inspection list form stored in the form storage unit 681.
Then, the determination item input unit 692 acquires the serial number of each part and the determination result of suitability for each part to be inspected, and inserts them into the inspection list acquired by the form acquisition unit 691. For example, the storage unit 680 stores the serial number of each component to be inspected in advance, and the form acquisition unit 691 reads the serial number and inserts it in the “serial No.” field. In addition, the determination item input unit 692 inserts the presence / absence of the response determined by the inspector in the “determination result” field as the determination result of the necessity of the response. It should be noted that a determination result indicating that no response is required is inserted for a component that has not been determined by the inspector (a component determined by the response necessity determination unit 292 that the response is unnecessary).

FIG. 15 is an explanatory diagram illustrating an example of a measure policy document generated by the inspection terminal device 600. The action policy document is a document attached to the second and subsequent sheets of the inspection report, and indicates the specific contents of the response policy determined by the inspector.
The “plant name” column and date column of the measure policy document in FIG. 15 are the same as the “inspection object” column and the “inspection date” column of the inspection list (FIG. 14), respectively.

The “model” column indicates the model of the plant (for example, the model of the gas turbine in the gas turbine power plant). The “part” column indicates the name of the part to which the part described in the measure policy document belongs.
The “name (event)” column indicates the name of the part described in the measure policy document and the type of nonconformity that has occurred.
The “event” area describes more detailed contents of the nonconformity that has occurred. In the “Proposed Measures” area, the response policy determined by the inspector is written.

  The form storage unit 681 stores a measure policy form for each part, and the form acquisition unit 691 reads a form corresponding to the part from the form storage unit 681. For example, the form storage unit 681 stores a form with a ring diagram in the “event” area as a ring form for the compressor compartment, and the form acquisition unit 691 reads the form.

The decision item input unit 692 inserts corresponding data into the “plant name” column, “model” column, “part” column, “product name” column, and date column of the form acquired by the form acquisition unit 691. Further, the decision item input unit 692 describes the response policy decided by the inspector in the “measure plan” area.
The inspector enters a non-conformity appearance such as a scratch on the “event” area diagram, and describes the non-conformity in the “event” area to complete the action policy document.

  Further, when the confirmation terminal device 300 transmits the necessity of the response determined by the inspector and the correction instruction for the response policy, the determination item input unit 692 rewrites the content of the measure policy document according to the correction instruction.

As described above, the form acquisition unit 691 acquires the inspection result report form based on the presence / absence of the response and the response policy determined by the operator. Then, the determination item input unit 692 inputs the determined presence / absence of the response and the response policy in the form of the inspection result report.
Thereby, the time for an inspector to create an inspection result report can be reduced.

  In addition, although the case where the function part for producing | generating an inspection result report was added to the structure in 2nd Embodiment as an example was demonstrated above, an inspection result report is added to the structure in 1st Embodiment. You may add the function part for producing | generating.

Note that a program for realizing all or part of the functions of the inspection support system 1, 2 and 3 is recorded on a computer-readable recording medium, and the program recorded on the recording medium is read by the computer system. The processing of each unit may be performed by executing. Here, the “computer system” includes an OS and hardware such as peripheral devices.
Further, the “computer system” includes a homepage providing environment (or display environment) if a WWW system is used.
The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Furthermore, the “computer-readable recording medium” dynamically holds a program for a short time like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. In this case, a volatile memory in a computer system serving as a server or a client in that case, and a program that holds a program for a certain period of time are also included.
