The CPU 21 determines whether or not all inspections have been completed based on the input from the operation unit 23 (step S9). When the inspection is not completed (NO in step S9), the process returns to step S2, and the subsequent processing is similarly performed for the next device.

  On the other hand, when it is determined that the inspection of all the devices is completed (YES in step S9), the request unit 212 of the CPU 20 transmits a storage request including the inspection result to the server 300 (step S10). This inspection result includes a captured image of the appearance of the inspection target device, a sound recorded from the inspection target device, an abnormal level determined by the inspector, and a treatment content determined by the inspector. Thereafter, the processing of the inspection terminal device 200 ends.

  The CPU 130 of the server 300 determines whether or not a storage request is received from the inspection terminal device 200 (step T6). When determining that the request is not received, the CPU 130 returns to step T1. On the other hand, when CPU 130 determines that the request has been received (YES in step T6), storage processing unit 323 stores the inspection result in inspection result DB 33A in accordance with the request (step T7). Thereafter, the processing of the server 300 ends.

(Display and operation in step S5)
The display on the display 25 in step S5 of FIG. 12 and the operation procedure of the inspector will be described. 13, FIG. 14 and FIG. 15 are diagrams showing examples of screens displayed in step S5 of FIG. The screen in FIG. 13 displays basic inspection information 250 based on “basic inspection items” and an icon 251. When the inspector operates the icon 251, the display control unit 211 displays the inspection device list 252 of FIG. 14 on the display 25 according to the screen data received from the server 300.

  FIG. 14 shows a display example of the inspection device list 252. The inspection device list 252 includes the device ID 51 extracted from the inspection result DB 33A corresponding to the identifier 50 indicating the substation (“A substation” in FIG. 13) designated by the basic inspection information 250 in FIG. 52, a list of data 255 including a model code 53 and an inspection date and time 54 are included. The display control unit 211 displays an icon 254 for displaying “detailed information” corresponding to each data 255 of the inspection device list 252. Further, the display control unit 211 displays an arrow icon 253 in association with the inspection device list 252. The icon 253 indicates data corresponding to the inspection target device input in step S2 among the data 255 of the inspection device list 252.

  In Embodiment 1, the display mode of the data of the inspection target device in the substation is not limited to the list form of FIG. For example, the display control unit 211 may display the data 255 of the relevant device on the display 25 while switching each time information on the inspection target device is input in step S2.

  The inspector can recognize that the data 255 indicated by the icon 253 in the inspection device list 252 is data of the inspection target device. When the inspector operates the icon 254 corresponding to the data 255 indicated by the icon 253, the display control unit 211 causes the display 25 to display information on the inspection item in step S5. An example of this display is shown in FIG.

(Display and operation in step S6)
The process of step S6 and step T5 will be described. FIG. 16 is a flowchart illustrating an example of the process of step S6. FIG. 17 is a flowchart illustrating an example of the process of step T5.

  The inspector performs the inspection according to the screen of FIG. 15 displayed in step S5. First, the display control unit 211 displays the screen of FIG. On the screen of FIG. 15A, basic inspection information 250, inspection items 256, a region 257 for displaying a captured image, and an icon 258 are displayed. The inspection item 256 includes an instruction of 'oil leakage' inspection and image photographing based on the inspection item 57 searched from the inspection result DB 33A and the image file ID 61. Further, an icon 258 and an icon 256A for instructing to search for reference information for inspection are displayed.

  The inspector checks whether there is an oil leak in the appearance of the inspection target device according to the inspection item 256 and operates the operation unit 23 to input the result of the inspection. Further, when there is oil leakage, the camera 33 captures the appearance of the device with oil leakage. The display control unit 211 displays the captured image from the camera 33 in the area 257 of FIG. Further, if there is a sound generated from the inspection target device, the inspector collects the sound with the microphone 34 and records it. The recorded voice data is stored in the RAM 22.

  The inspector operates the icon 258 to obtain support information when determining the abnormal level of oil leakage. When the receiving unit 210 receives the operation content of the icon 258, the display control unit 211 switches the screen of the display 25 from the screen of FIG. 15A to the screen of FIG. 15B according to the received operation content.

  When the icon 258 is operated, that is, when the screen of FIG. 15B is displayed, the CPU 20 starts the process of FIG.

  On the screen of FIG. 15B, the icon 258 of FIG. 15A is switched to icons 258A and 258B. The icon 258A is operated to display inspection information including the previous inspection result of the inspection target device. Further, the icon 258B is operated to display inspection information of another device of the same type as the inspection target device.

  Referring to FIG. 16, accepting unit 210 accepts the operation content of icon 258A or 258B by the inspector (step S11).

<Display previous information>
When the operation content of the inspector indicates the operation of the icon 258A (“previous information” in step S12), the request unit 212 transmits a request for the previous inspection information of the inspection target device to the server 300 (step S13). On the other hand, when the operation content of the inspector indicates the operation of the icon 258B (“same type information” in step S12), the request unit 212 transmits a request for inspection information of another device of the same type as the inspection target device to the server 300. (Step S13).

  First, a case where 'previous information' is requested will be described. When the CPU 130 of the server 300 receives the request from the inspection terminal device 200 (step T8), the search unit 324 searches the various DBs 330 according to the received request to acquire the previous information (step T10).

  Specifically, the search unit 324 searches the inspection result DB 33A of 'A substation' based on the device number received in step T1, and the search results in the latest associated with the device ID 51 corresponding to the device number. Inspection date and time 54, abnormality level 59, treatment content 60A, skill 60B and image data 63 are read as previous information. In this case, the search unit 324 acquires the treatment content 60A associated with the treatment DB 33C based on the treatment ID 60 associated with the device ID 51. Further, the search unit 324 acquires the skill level 60B associated with the inspector DB 33D based on the inspector code 55 associated with the device ID 51.

  The screen generation unit 322 generates screen data from the acquired previous information. The server 300 transmits the generated screen data to the inspection terminal device 200 (step T12).

  When the CPU 20 of the inspection terminal device 200 receives the screen data of the previous information from the server 300 (step S14), the display control unit 211 drives the display 25 according to the received screen data. As a result, the screen of the display 25 is switched from the screen of FIG. 15B to the screen of FIG.

  In FIG. 15C, an image captured by the camera 33 of the inspection target device and the previous information 259 received from the server 300 are displayed in the area 257 on the same screen. The inspector can obtain information for supporting the determination of the inspection result from the screen of FIG.

  Specifically, the inspector can determine the degree of progress of oil leakage by comparing the appearance image 631 of the previous information 259 with the captured image of the region 257. Further, the abnormality level and the treatment content at the current inspection can be determined from the degree of progress, the abnormality level 59 (level A) of the previous information 259, and the treatment content 60A ('look'). Furthermore, the reliability of the previous information 259 can be obtained from the proficiency 60B of the inspector at the previous inspection.

  For example, when there is no significant change in the oil leakage image compared to the length of time elapsed since the most recent inspection date and time, the inspector determines that the abnormality level 256B is the same 'level A' as the previous time. (See FIG. 15C). Further, when the skill level 60B of the inspector at the previous inspection is high, it can be determined that the previous treatment content 60A is reliable, and the inspector can confirm that the current treatment content is the same as the previous time. It becomes possible to decide on 'seeing'.

  On the other hand, for example, when the oil leakage is larger than the length of time elapsed from the most recent inspection date and time, the inspector sets the abnormality level 256B to an abnormality level higher than the previous “level A”. It is possible to judge that Also, if the inspector's proficiency 60B at the previous inspection is high, the previous treatment content can be determined to be reliable, and the inspector can determine that the current treatment content is higher than the previous emergency. It is possible to obtain a guideline that it may be determined that the communication is “manufacturer contact”.

  FIG. 15D shows a display screen when the audio data 65 has been acquired as the previous information 259. In FIG. 15D, the audio data icon 257A recorded at the time of the current inspection and the audio data 65 icon 259A of the previous information 259 are displayed on the same screen. When the icon 257A is operated, the CPU 20 reproduces the audio data in the RAM 22 recorded at the time of the current inspection. Further, when the icon 259B is operated, the CPU 20 reproduces the audio data 65 included in the previous information 259. Audio is output from the speaker 35 in accordance with the reproduced audio data.

  If the inspector hears and compares the reproduced sound and determines that there is no change in the sound emitted by the inspection target device, the inspector determines that the abnormality level 256B is the same 'level A' as the previous time. (See FIG. 15D). Further, when the proficiency level 60B of the inspector in the previous information 259 is high, it can be determined that the previous treatment content 60A is reliable, and the inspector can confirm that the current treatment content is the same as the previous time. It will be possible to make a decision that it may be decided.

  On the other hand, for example, when the generated sound volume is larger than the length of time elapsed since the most recent inspection date and time, the inspector sets the abnormality level 256B to an abnormality higher than the previous 'level A'. It becomes possible to judge that it should be a level. Further, when the proficiency level 60B of the inspector of the previous information 259 is high, it can be determined that the previous treatment content 60A is reliable, and the inspector can determine that the current treatment content is higher than the previous information. It can be determined that the maker contact is urgent.

  Note that the criterion for determining the sound to be generated is not limited to the volume level. This criterion may include the frequency of the sound (sound pitch) and the frequency at which the sound occurs.

<Display of similar information>
When the received operation content indicates the operation of the icon 258B (“same type information” in step S12), the request unit 212 transmits a request for inspection information of another device of the same type as the inspection target device to the server 300 (step S12). S16).

  The CPU 130 of the server 300 receives the request for similar information ('same information' in steps T8 and T9). The search unit 324 acquires the same kind of inspection information by searching the various DBs 330 in accordance with the received request (step T11).

  Specifically, the search unit 324 searches the inspection result DB 33A of each substation based on the device number of the inspection target device received in step T1. The retrieval unit 324 retrieves the latest inspection date / time 54, abnormality level 59, treatment content 60A, skill 60B, and image data associated with the device ID 51 corresponding to the device number of the device to be inspected from each inspection result DB 33A. 63 is read out as the same kind information. In this case, the search unit 324 acquires the treatment content 60A associated with the treatment DB 33C based on the treatment ID 60 associated with the device ID 51 and associates it with the device ID 51 as in the case of the “previous information”. Based on the inspector code 55, the skill level 60B associated with the inspector DB 33D is acquired.

  The screen generation unit 322 generates screen data based on the same kind of information acquired from each inspection result DB 33A. The server 300 transmits the generated screen data to the inspection terminal device 200 (step T12).

  The CPU 20 of the inspection terminal device 200 receives screen data of the same type information from the server 300 (step S17). The display control unit 211 drives the display 25 according to the received screen data. As a result, the screen of the display 25 is switched from FIG. 15B to a screen for displaying the same type of information (step S18).

  For example, when N (N> 1) pieces of similar information are acquired, the display control unit 211 performs FIG. 15C (or FIG. 15D) for each of the N pieces of similar information based on the screen data. ) Is displayed on the display 25. The inspector compares the appearance image with the captured image of the same kind of information, or compares the reproduced sound of the abnormal sound of the same kind of information with the abnormal sound detected this time (or the recorded abnormal sound), thereby obtaining an abnormal level. Can be judged. When determining the abnormal level, it is possible to determine the abnormal level 256B and the treatment content based on the current inspection with reference to the same type of information including the abnormal level 59, the skill level 60B, and the treatment content 60A.

  Further, out of the N pieces of similar information, the same kind of information associated with the working day at the same time as the working day 333 of the inspection target device may be extracted and output as support information. As a result, when the degree of oil leakage or abnormal sound of the inspection target device is larger than that of other devices whose operation day 333 is the same period, the inspector can check whether the inspection target device has oil leakage or abnormal sound. Can be determined to be abnormal regardless of the length of operation time.

  In the <display of similar information> described above, the inspection result DB 33A of another substation is also set as a search target, so that the inspector determines the abnormality level 256B and the content of treatment compared to <display of previous information>. Support information can be diversified.

(Display modification)
FIG. 18 is a diagram illustrating another example of the screen display of previous information or similar information according to the first embodiment. FIG. 19 is a diagram illustrating still another example of the screen display of the previous information or similar information according to the first embodiment. In FIG. 15C and FIG. 15D, the search unit 324 searches only the latest inspection information as the previous information or similar information, and the display 25 displays only the searched latest inspection information. . In this modification, the search target is not limited to the latest inspection information, but M (however, M ≧ 2) pieces of inspection information that are traced back to the past are searched.

  Referring to FIG. 18, display control unit 211 displays M inspection information screens while switching them based on screen data from server 300. In the upper part of FIG. 18, basic inspection information 250 and inspection items 256, inspection date / time 251 </ b> A and inspection date / time 251 </ b> B of a plurality of inspection information retroactive to the past, and pull-down menus W <b> 1 and W <b> 2 are displayed. The pull-down menu W1 displays abnormal level options ('A', 'B', and 'C'), and the pull-down menu W2 displays treatment content options ('watching', 'extraordinary inspection', and 'manufacturer contact'). ) Is displayed.

  In the lower part of the screen of FIG. 18, the captured image of the current inspection target device in the region 257 and the inspection information (captured image data of the past i (i = 1, 2, 3... M) -th inspection date and time 251C). An area 290 for displaying an appearance image based on 63, an abnormality level 59 and treatment content 60A), an icon 291 and an icon 292 are displayed.

  The icon 291 is displayed when the i-th inspection information being displayed in the area 290 includes the audio data 65. The icon 292 is operated when switching past inspection information displayed in the area 290. When the inspector operates the icon 292, the reception unit 210 receives the operation content, and the display control unit 211 changes the i-th inspection information in the area 290 to the next (i + 1th or i-1th) according to the received operation content. ) Switch to inspection information.

  The inspector compares the captured image of the region 257 with the appearance image based on the image data 63, and based on the result, the inspection result (in this case, the inspection date / time 251C, the abnormality level 59, and the treatment content 60A in the region 290) (Including abnormal level and treatment details). The inspector operates the operation unit 23 to select an abnormality level and a treatment content from the pull-down menu W1 and the pull-down menu W2 based on the determination result.

  When the inspector operates the icon 291 in FIG. 18, the receiving unit 210 receives the operation content. The display control unit 211 switches the screen of the display 25 to the screen of FIG. 19 according to the accepted operation content. In the screen of FIG. 19, icons 257A and 259A for reproducing sound are displayed instead of images.

  When the inspector operates the icon 257A, the reproduction sound according to the sound data recorded by the current inspection target device is output from the speaker 35, as in FIG. Further, when the icon 259A is operated, the reproduction sound according to the sound data 65 of the abnormal sound recorded at the inspection date and time 251C is output from the speaker 35, as in FIG.

  According to the modification shown in FIG. 18 and FIG. 19, a plurality of pieces of inspection information dating back to the past can be provided to the inspector as support information for determining the abnormality level and the treatment content.

  As a modification, the inspection information to be searched retroactively may be narrowed down by setting in advance the retroactive time or the number of retrospective searches. The inspector can operate the operation unit 23 to variably set the retroactive time or the number of cases searched retroactively.

(Example of inspection result display)
FIG. 20 is a diagram showing an example of the display of the inspection result list according to the first embodiment. When the inspection information is transmitted at the end of inspection in step S10 of FIG. 12, the display control unit 211 displays the inspection result list shown in FIG.

  The inspection result list of FIG. 20 is obtained by adding the information 255A and the result 255B of the inspected category and inspection item to the data 255 of the inspection device list 252 of FIG. The inspector confirms the inspection result list of FIG. 20 to confirm that there are no inspection omissions and the general tendency of the inspection results (for example, there are many devices with high abnormal levels or few devices with low abnormal levels). ) Can be confirmed.

  In the first embodiment, the inspection is performed using images or sounds, but information measured for the inspection is not limited to images or sounds. For example, the inspection may be performed using heat generation or vibration from the inspection target device. In that case, measurement using a temperature sensor of the sensor 36 or measurement using a vibration sensor is performed.

  The temperature sensor is not limited to the sensor 36 provided in the inspection terminal device 200. For example, the temperature sensor for measurement may include another portable sensor different from the sensor 36 of the inspection terminal device 200 or a sensor mounted in advance on an inspection target device.

(Modification of device identification method)
In Embodiment 1, the identification ID 78 for identifying the device to be inspected is acquired from the RF tag 70, but the acquisition method for the identification ID 78 is not limited to this. For example, the CPU 20 or the CPU 130 may uniquely specify the inspection target device from the position information of the inspection terminal device 200.

(Modification of determining treatment details)
In the first embodiment, the CPU 20 or the CPU 130 may determine an abnormal level or treatment content and present it to the inspector. For example, the CPU 20 or the CPU 130 determines the difference between the oil leakage range (area) representing the oil leakage amount of the oil leakage image at the latest inspection, the oil leakage amount at the current inspection, and the elapsed time from the latest inspection. Based on the length of the product, estimate the speed of progress of the abnormality (oil leakage), and based on the result of the estimation, any of the details of the treatment, including the appearance until the next inspection (no action required), temporary inspection, and manufacturer contact And the contents of the determination may be presented to the inspector via the display 25.

Embodiment 2. FIG.
The second embodiment shows a modification of the first embodiment. In the second embodiment, when the CPU 20 of the inspection terminal device 200 or the CPU 130 of the server 300 displays the captured image and the appearance image 631 on the display 25, both images have the same attributes regarding the display mode including brightness. After the image processing is performed, the image is displayed on the display 25.

  The image processing includes correction processing that makes the brightness of the image at the time of display constant, and processing that corrects distortion of the image at the time of display. The image processing is not limited to the case where the image processing is performed, and may be performed when the captured image is stored as the image data 63 in the inspection result DB 33A. Note that the brightness correction processing may be performed using the brightness measured by the brightness sensor of the sensor 36 at the time of imaging. In the distortion correction processing, processing may be performed using the angle of the camera 33 measured by the tilt sensor of the sensor 36 at the time of imaging.

  Thereby, for example, even in the case of equipment of the same model, the environment provided for each substation is different (for example, the difference between indoor illumination light and outdoor natural light), or when the camera 33 captures an image of the equipment The captured image and the appearance image 631 are displayed on the display 25 in a state in which changes in attributes (brightness, distortion) of the captured image due to differences in imaging conditions including differences in angles are eliminated. Therefore, the inspection terminal device 200 or the server 300 can assist the inspector to more accurately determine the abnormal level or the treatment content based on the comparison between the captured image of the region 257 and the appearance image 631. Become.

(Modification of image processing)
When the inspector images the appearance of the device, the CPU 20 may output advice to the inspector so that the image is taken from the same angle as the appearance image 631 based on the output of the tilt sensor of the sensor 36. .

(Modification of image file stored in storage unit)
In the above embodiment, the image data 63 obtained by imaging has been described as an abnormal appearance image. However, external appearance image data determined to be normal without abnormality may be stored in the storage unit. Thereby, the image of the external appearance judged to be normal can be displayed on the inspector. Therefore, for example, when there is a case where it is determined to be normal depending on the amount of oil leakage, it is possible to indicate to the inspector a standard for how much oil leakage can be determined to be normal.

  Furthermore, when an oil leak having an external appearance determined to be abnormal is treated, an image after treatment may be taken and stored in the storage unit. Thus, by storing the history of treatments performed for abnormalities as image data, the history of treatments can be visually provided to the inspector as an image.

Embodiment 3 FIG.
The third embodiment shows a modification of the first or second embodiment. In the third embodiment, as described above, when N pieces of similar information are displayed, the CPU 20 of the inspection terminal device 200 or the CPU 130 of the server 300 displays the same kind of information including the appearance image 631 as an associated abnormality. It is displayed on the display 25 in the order according to the order from the highest or the lowest level 59.

  Alternatively, the CPU 20 of the inspection terminal device 200 or the CPU 130 of the server 300 performs image processing for calculating the similarity between the captured image and each appearance image 631, and displays the appearance images 631 on the display 25 in descending order of similarity. Also good. The image similarity may include an abnormality range similarity, a color similarity, and a shape similarity indicated by the image. Further, the display may be performed in the order in which the abnormality level 59 and the similarity are combined. The order according to the similarity of images can be applied to sound as well. Also, the sound similarity may include a sound volume similarity, a sound pitch (frequency) similarity, and a sound generation frequency similarity.

  The appearance image 631 is displayed in the order according to the similarity of the attributes of the device. CPU20 reads the attribute which the apparatus of an external appearance image has, and the attribute which the apparatus (inspection object apparatus) of a captured image has from the apparatus DB33B, and determines the similarity of both read-out attributes according to a predetermined reference | standard. When displaying the appearance image on the display 25, the CPU 20 displays the images in the order in which the determination is made in descending order of similarity. Similarly, the reproduction of the audio data 65 is performed in the order according to the similarity of the attributes of the device.

  The attribute of the device may include at least one of the model indicated by the model code, the manufacturing year of the device, the installation environment condition of the device, and the operating environment condition of the device, but the attribute type is not limited to these. For example, if the model is the same, the CPU 20 determines a high similarity. If the production year is the same, a high similarity is determined. If the installation environment conditions are the same, a high similarity is determined. If the operating environment conditions are the same, a high similarity is determined. The installation environment condition includes, but is not limited to, at least one of a mountain area, a beach area, a plateau area, and a rural area, an urban area and a non-urban area, and an indoor / outdoor area. In addition, the operating environment condition is a condition that represents the situation around the device, and includes at least one of temperature, humidity, noise (volume, frequency, frequency), and amount of solar radiation, but is not limited thereto.

  Further, when displaying the appearance image on the display 25, the CPU 20 displays the appearance image in the order in which the skill level 60B associated with the appearance image is high. Similarly, in the reproduction of the audio data 65, the audio data 65 is reproduced in the order in descending order of the skill level 60B associated with the audio data 65.

  As a result, the inspector can select N in the order according to one of the order of the height of the abnormal level, the order of the similarity of the image (or sound), the degree of similarity of the model attribute, or the skill level 60B. It is possible to display and confirm support information for determining an abnormal level or treatment content while switching the same kind of information. Note that the order of switching display is also the order according to the combination of two or more of the order of abnormality level height, the order of similarity of images (or sounds), the degree of similarity of model attributes, or the skill level 60B. May be included.

Embodiment 4 FIG.
The fourth embodiment shows a modification of each of the above embodiments. In the fourth embodiment, the CPU 20 of the inspection terminal device 200 stores the inspection information (captured image, audio data, abnormality level and treatment content) acquired in steps S6 to S8 in the memory 72 of the RF tag 70 with the previous information 76. Store as. Thereby, the latest inspection information can be stored in the memory 72 of the RF tag 70 of the inspection target device.

  According to the fourth embodiment, in the processing of steps S13 to S15 in FIG. 16, the CPU 20 can also acquire the previous information by communicating with the RF tag 70 without communicating with the server 300. Therefore, for example, the CPU 20 may measure the traffic of the network 8 and switch the previous information acquisition path from the network 8 to the communication with the RF tag 70 when the traffic is heavy.

Embodiment 5. FIG.
Embodiment 5 shows a modification of each of the above embodiments. In the fifth embodiment, the audio data output when the icon 257A is operated and the audio data output when the icon 259A is operated have characteristics (for example, predetermined values) corresponding to the device. And pass through a bandpass filter having a bandwidth. The characteristic is a bandwidth in which an abnormal sound that can be generated from the device can be accurately extracted, and a noise component that occurs in the surrounding environment of the device can be removed.

  According to the fifth embodiment, for example, even if the devices are of the same model, the sound caused by the difference in recording conditions including that the environment provided for each substation is different (for example, the difference between indoors and outdoors) Audio can be output in a state where fluctuations in attributes (for example, noise frequency) are eliminated. Therefore, it is possible to assist the inspector so that the determination of the abnormal level or the treatment content based on the comparison between voices can be performed more accurately.

Embodiment 6 FIG.
The sixth embodiment shows a modification of each of the above embodiments. The functions of the system 100 according to the first to fifth embodiments are realized by the inspection terminal device 200 that functions as a stand-alone terminal. Specifically, in the first to fifth embodiments, the inspection terminal device 200 functions as a client terminal of the server 300. However, in the sixth embodiment, the inspection terminal device 200 is a stand-alone device independent of the server 300. Function as a type terminal.
