This inspection result includes a captured image of the appearance of the equipment to be inspected, a voice recorded from the equipment to be inspected, an abnormality level judged by the inspector, and the action content judged by the inspector. After that, the processing of the inspection terminal device 200 ends.

The CPU 130 of the server 300 determines whether or not to receive the storage request from the inspection terminal device 200 (step T6). When the CPU 130 determines that the request is not received, the CPU 130 returns to step T1. On the other hand, when the CPU 130 determines that the request has been received (YES in step T6), the storage processing unit 323 stores the inspection result in the inspection result DB 33A according to the request (step T7). After that, 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, 14 and 15 are diagrams showing a screen example displayed in step S5 of FIG. The screen of FIG. 13 displays the inspection basic information 250 and the icon 251 based on the “inspection basic item”. When the inspector operates the icon 251 the display control unit 211 causes the display 25 to display the inspection device list 252 of FIG. 14 according to the screen data received from the server 300.

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

In the first embodiment, the display mode of the data of the equipment to be inspected at the substation is not limited to the list format of FIG. For example, the display control unit 211 may display the data 255 of the device on the display 25 while switching each time the information of the device to be inspected is input in step S2.

The inspector can recognize that the data 255 pointed to by the icon 253 in the inspection equipment list 252 is the data of the inspection target equipment. 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 the information of the inspection item in step S5. An example of this display is shown in FIG.

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

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

The inspector inspects the appearance of the equipment to be inspected for oil leakage according to the inspection item 256, and inputs the inspection result by operating the operation unit 23. Further, when there is an oil leak, the appearance of the device having the oil leak is imaged by the camera 33. The display control unit 211 displays the captured image from the camera 33 in the area 257 of FIG. 15 (A) so as to display the captured image. Further, if there is a sound generated from the device to be inspected, the inspector collects the sound by the microphone 34 and records it. The recorded voice data is stored in the RAM 22.

In addition, the inspector operates the icon 258 in order to obtain support information when determining the abnormal level of the oil leak. When the reception 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. 15 (A) to the screen of FIG. 15 (B) according to the received operation content.

The CPU 20 starts the process of FIG. 16 when the icon 258 is operated, that is, when the screen of FIG. 15B is displayed.

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

With reference to FIG. 16, the reception unit 210 receives the operation content of the icon 258A or 258B by the inspector (step S11).

<Display of previous information>
When the operation content of the inspector indicates the operation of the icon 258A ('previous information' in step S12), the requesting unit 212 transmits a request for the previous inspection information of the device to be inspected to the server 300 (step S13). On the other hand, when the operation content of the inspector indicates the operation of the icon 258B ('similar information' in step S12), the request unit 212 transmits a request for inspection information of another device of the same type as the device to be inspected 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 a request from the inspection terminal device 200 (step T8), the search unit 324 acquires the previous information by searching various DB 330s according to the received request (step T10).

Specifically, the search unit 324 searches the inspection result DB33A of the'A substation'based on the device number received in step T1, and by the search, the latest one associated with the device ID 51 corresponding to the device number. The inspection date and time 54, the abnormality level 59, the treatment content 60A, the skill level 60B, and the image data 63 are read out as the 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. 15 (B) to the screen of FIG. 15 (C).

In FIG. 15C, the image captured by the camera 33 of the device to be inspected 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 assisting the judgment of the inspection result from the screen of FIG. 15C.

Specifically, the inspector can determine the degree of progress of the oil leak 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 time of this 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 ('wait-and-see'). Further, it is possible to obtain the reliability of the previous information 259 from the skill level 60B of the inspector at the time of the previous inspection.

For example, if there is no significant change in the oil leak image compared to the length of time elapsed from the latest inspection date and time, the inspector determines that the abnormality level 256B is the same'level A'as the previous time. This is possible (see FIG. 15C). In addition, if the inspector's skill level 60B at the time of the previous inspection is high, it can be judged that the previous treatment content 60A is reliable, and the inspector can determine that the current treatment content is the same as the previous one. It becomes possible to decide to see.

On the other hand, for example, when the oil leak is larger than the length of time elapsed from the latest inspection date and time, the inspector sets the abnormality level 256B to a higher abnormality level than the previous'level A'. It becomes possible to judge that it should be done. In addition, if the inspector's skill level of 60B at the time of the previous inspection is high, it can be judged that the previous treatment content is reliable, and the inspector can determine that the current treatment content is higher than the previous treatment. It is possible to obtain a guideline that it may be judged as a'manufacturer contact'with a characteristic.

FIG. 15D shows a display screen when the voice data 65 is acquired as the previous information 259. In FIG. 15D, the voice data icon 257A recorded at the time of this inspection and the voice 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 voice data of the RAM 22 recorded at the time of this inspection. Further, when the icon 259B is operated, the CPU 20 reproduces the voice data 65 included in the previous information 259. Audio is output from the speaker 35 according to the reproduced audio data.

If the inspector hears the reproduced voice and determines that there is no change in the sound emitted by the device to be inspected, the inspector determines that the abnormality level 256B is the same'level A'as the previous time. Is possible (see FIG. 15 (D)). In addition, if the inspector's skill level 60B of the previous information 259 is high, it can be judged that the previous treatment content 60A is reliable, and the inspector can determine that the current treatment content is the same as the previous time. It is possible to judge that it is okay to make a decision.

On the other hand, for example, when the generated volume is louder than the length of time elapsed from the latest 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 inspector's skill level 60B 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 treatment content. It can be judged as an urgent'contact with the manufacturer'.

The criterion for determining the generated sound is not limited to the loudness of the volume. This criterion may include the frequency of the sound (pitch) and the frequency of occurrence of the sound.

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

The CPU 130 of the server 300 receives the request for the same kind of information ('similar information' in steps T8 and T9). The search unit 324 acquires the same type of inspection information by searching various DB 330s according to 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 device to be inspected received in step T1. The search unit 324 searches from each inspection result DB 33A to the latest inspection date and time 54, abnormality level 59, treatment content 60A, skill level 60B, and image data associated with the device ID 51 corresponding to the device number of the device to be inspected. 63 is read out as the same kind of 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'previous information'. Based on the inspector code 55, the skill level 60B associated with the inspector DB33D is acquired.

The screen generation unit 322 generates screen data based on the same type 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 of 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. 15 (B) to a screen for displaying the same type of information (step S18).

For example, when N (N> 1) pieces of the same type of information are acquired, the display control unit 211 bases the screen data on FIG. 15 (C) (or FIG. 15 (D)) for each of the N pieces of the same type of information. ) Is displayed on the display 25. The inspector can compare the appearance image of the same type of information with the captured image, or compare the reproduced sound of the abnormal sound of the same type of information with the abnormal sound (or recorded abnormal sound) detected this time to obtain the abnormal level. Can be judged. In determining the abnormality level, the abnormality level 256B and the treatment content can be determined based on this inspection with reference to the same type of information including the abnormality level 59, the skill level 60B, and the treatment content 60A.

Further, from the N pieces of the same type of information, the same type of information associated with the working day of the device to be inspected at the same time as the working day 333 may be extracted and output as support information. As a result, when the degree of oil leakage or abnormal noise of the equipment to be inspected is larger than that of other equipment having the same working day 333, the inspector can check the oil leakage or abnormal noise of the equipment to be inspected. Can be determined to be abnormal regardless of the length of operating time.

In the above-mentioned <display of similar information>, the inspection result DB33A of other substations is also searched, so that the inspector determines the abnormality level 256B and the treatment content as compared with the <display of the previous information>. Support information for this can be diversified.

(Example of display modification)
FIG. 18 is a diagram showing another example of screen display of previous information or similar information according to the first embodiment. FIG. 19 is a diagram showing still another example of screen display of previous information or similar information according to the first embodiment. In FIGS. 15 (C) and 15 (D), the search unit 324 searches only the latest inspection information as the previous information or the same type of 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, and M (however, M ≧ 2) inspection information retroactive to the past is searched.

With reference to FIG. 18, the display control unit 211 displays the screens of M inspection information while switching the screens based on the screen data from the server 300. In the upper part of FIG. 18, the inspection basic information 250 and the inspection item 256, the inspection date and time 251A and the inspection date and time 251B of a plurality of inspection information retroactively, and the pull-down menus W1 and W2 are displayed. The pull-down menu W1 displays abnormal level options ('A',' B'and'C'), and the pull-down menu W2 displays treatment options ('wait-and-see','temporary inspection' and'manufacturer contact'. ) Is displayed.

In the lower part of the screen of FIG. 18, the captured image of the device to be inspected this time in the area 257 and the inspection information (image data captured) at the past i (i = 1, 2, 3 ...

The icon 291 is displayed when the i-th inspection information displayed in the area 290 includes the voice data 65. The icon 292 is operated when switching the 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 places the i-th inspection information in the area 290 next (i + 1th or i-1st) according to the received operation content. ) Switch to the inspection information.

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

When the inspector operates the icon 291 in FIG. 18, the reception unit 210 accepts the operation content. The display control unit 211 switches the screen of the display 25 to the screen of FIG. 19 according to the received operation content. On the screen of FIG. 19, instead of the image, icons 257A and 259A for reproducing the sound are displayed.

When the inspector operates the icon 257A, the reproduced voice according to the voice data recorded by the device to be inspected this time is output from the speaker 35 as in FIG. 15 (D). Further, when the icon 259A is operated, the reproduced 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. 15 (D).

According to the modified examples shown in FIGS. 18 and 19, it is possible to provide the inspector with a plurality of inspection information retroactively 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 the retroactive time or the number of retroactively searched cases in advance. The retroactive time or the number of retroactively searched cases can be variably set by the inspector by operating the operation unit 23.

(Display example of inspection result)
FIG. 20 is a diagram showing an example of displaying the inspection result list according to the first embodiment. When the inspection information is transmitted at the end of the inspection in step S10 of FIG. 12, the display control unit 211 displays the inspection result list shown in FIG. 20 on the display 25.

The inspection result list of FIG. 20 is obtained by adding information 255A and result 255B of the inspection classification and inspection item to the data 255 of the inspection equipment list 252 of FIG. By checking the inspection result list in FIG. 20, the inspector confirms that there are no inspection omissions and that there is a general tendency of the inspection results (for example, there are many equipment with high abnormality level or few equipment with low abnormality level). ) Can be confirmed.

In the first embodiment, the inspection is performed using an image or sound, but the information measured for the inspection is not limited to the image or sound. For example, the inspection may be performed using heat generation or vibration from the equipment to be inspected. In that case, the measurement using the temperature sensor of the sensor 36 or the measurement using the vibration sensor is performed.

The above 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 pre-mounted on the device to be inspected.

(Modified example of device identification method)
In the first embodiment, 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 identify the device to be inspected from the position information of the inspection terminal device 200.

(Modified example of determining the treatment content)
In the first embodiment, the CPU 20 or the CPU 130 may determine the abnormality level or the treatment content and present it to the inspector. For example, the CPU 20 or CPU 130 has the difference between the oil leak image at the time of the latest inspection and the oil leak range (area) representing the oil leak amount of the oil leak image at the time of this inspection, and the elapsed time from the latest inspection. Estimate the speed of progress of the abnormality (oil leak) based on the length of the oil, and based on the estimation result, one of the treatment contents including wait-and-see (no treatment required), temporary inspection, and manufacturer contact until the next inspection. May be determined and the content of the decision may be presented to the inspector via the display 25.

Embodiment 2.
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 performing image processing so as to be, it is displayed on the display 25.

The above image processing includes a correction process for making the brightness of the image at the time of display constant, and a process for correcting the distortion of the image at the time of display. The image processing is not limited to the case where the image processing is performed when the image is displayed, and may be performed when the captured image is stored in the inspection result DB 33A as the image data 63. The brightness correction process may be performed using the brightness measured by the brightness sensor of the sensor 36 at the time of imaging. Further, in the distortion correction processing, the angle of the camera 33 measured by the tilt sensor of the sensor 36 at the time of imaging may be used.

As a result, for example, even if the devices are of the same model, the environment provided for each substation is different (for example, the difference between the indoor illumination light and the outdoor natural light), or the device is imaged by the camera 33. The captured image and the appearance image 631 are displayed on the display 25 in a state in which fluctuations 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 abnormality level or the treatment content based on the comparison between the captured image of the area 257 and the appearance image 631. Become.

(Modified example 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 example of the image file stored in the storage unit)
In the above embodiment, the image data 63 obtained by imaging has described the image of the appearance abnormality, but the image data of the appearance which is judged to be normal without any abnormality may be stored in the storage unit. As a result, the inspector can display an image of the appearance judged to be normal. Therefore, for example, when there is a case where it is judged to be normal depending on the amount of oil leakage, it is possible to show the inspector a standard as to how much oil leakage can be judged to be normal.

Further, when the oil leak having an appearance determined to be abnormal is treated, the image after the treatment may be captured and stored in the storage unit. As a result, by storing the history of the treatment taken for the abnormality as image data, it is possible to visually provide the inspector with the history of the treatment as an image.

Embodiment 3.
The third embodiment shows a modification of the first or second embodiment. In the third embodiment, when displaying N pieces of the same kind of information as described above, the CPU 20 of the inspection terminal device 200 or the CPU 130 of the server 300 associates the same kind of information including the appearance image 631 with the abnormality. The display 25 is displayed in the order of the highest level 59 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 image 631 on the display 25 in descending order of similarity. May be good. The similarity of the images may include the similarity of the range of anomalies indicated by the image, the similarity of colors and the similarity of shapes. Further, it may be displayed according to the order in which the abnormality level 59 and the similarity are combined. The order of image similarity can be applied to audio as well. Further, the similarity of voice may include the similarity of loudness, the similarity of pitch (frequency), and the similarity of sound generation frequency.

Further, the appearance image 631 is displayed in an order according to the similarity of the attributes possessed by the device. The CPU 20 reads the attributes of the external image device and the attributes of the captured image device (inspection target device) from the device DB 33B, and determines the similarity between the read attributes according to a predetermined standard. When displaying the appearance image on the display 25, the CPU 20 displays the appearance images in the order of increasing similarity in which the determination is made. Similarly, the reproduction of the audio data 65 is performed in an order according to the similarity of the attributes possessed by the device.

The above device attributes may include at least one of the model indicated by the model code, the year of manufacture of the device, the installation environment conditions of the device, and the operating environment conditions of the device, but the types of attributes are not limited thereto. For example, the CPU 20 determines a high degree of similarity if the models are the same. Also, if the year of manufacture is the same, a high degree of similarity is judged. If the installation environment conditions are the same, a high degree of similarity is judged. If the operating environment conditions are the same, a high degree of similarity is determined. The installation environmental conditions include, but are not limited to, at least one of mountainous areas, beach areas, plateau areas and rural areas, urban areas and non-urban areas, and indoor / outdoor areas. Further, the operating environment condition is a condition representing the surrounding condition of the device, and includes, but is not limited to, at least one of temperature, humidity, noise (volume, frequency, frequency) and the amount of solar radiation.

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

As a result, the inspector can perform N in the order of the height of the abnormal level, the order of the similarity of the image (or sound), the order of the similarity of the model attribute, or the order according to one of the skill level 60B. It is possible to display and confirm the support information for determining the abnormality level or the treatment content while switching the same type of information. In addition, the order of switching display may be the order of the height of the abnormal level, the order of the similarity of the image (or sound), the order of the similarity of the model attribute, or the order according to two or more combinations of the skill level 60B. Can include.
