[First Embodiment]
A first embodiment of a defect inspection system, a defect inspection method, and a defect inspection program according to the present application will be described. In the present embodiment, an inspection system for various devices installed in an industrial plant is exemplified as a defect inspection.

FIG. 6 is a layout diagram of various devices installed in an industrial plant. In an area 20 shown in FIG. 6, a large number of various devices 21 indicated by icon marks are arranged. and inspect the equipment for corrosion, deformation, damage, etc. This inspection is continuously repeated, for example, once a year. Inspection workers enter inspection results from mobile terminals, and the inspection data are wirelessly transmitted to a server that centrally manages the system.

(Description of the hardware configuration of the inspection system)
The hardware configuration of the inspection system according to this embodiment will be described with reference to FIG. The server 1 includes a server control section 2, a memory 3 and a communication section 4. The mobile terminal 10 also includes a mobile control unit 11 , an input unit 12 , an imaging unit 13 , a memory 14 , a display unit 15 and a communication unit 16 . The server 1 and the mobile terminal 10 perform wireless communication via the communication unit 4 and the communication unit 16, respectively, and transmit and receive data.

When performing an inspection, the display unit 15 of the portable terminal 10 displays a screen such as a drawing corresponding to the equipment to be inspected. An imaging unit 13 is used to capture an image of an object to be inspected, and the display unit 15 displays the image. These input data are stored in memory 14 and transmitted to server 1 .

Then, the server 1 stores and accumulates the input data transmitted from the mobile terminal 10 in the memory 3 . Further, the server control unit 2 controls the display etc. of the display unit 15 of the mobile terminal 10 according to a predetermined program for examination data recording processing.

(Description of inspection data recording process: when there is no previous input data)
Next, a program for examination data recording processing executed by the server control unit 2 of the server 1 will be described according to the flowchart of FIG. First, the server control unit 2 determines whether or not there is an input specifying a target device from the input unit 12 of the mobile terminal 10 (step S2). The inspection worker carrying the portable terminal 10 inputs the identification number of the device to be inspected from the input unit 12 just before performing the inspection.

In this case, the layout of various devices shown in FIG. 6 may be displayed on the display unit 15 of the mobile terminal 10, and the icon mark of the specific device 21 may be tapped to input the designation of the target device. . It is also possible to read a bar code or QR code (registered trademark) attached directly to the device 21 with a reading device and input designation of the device.

When there is an input specifying a target device from the mobile terminal 10, the server control unit 2 refers to the data accumulated in the memory 3, and the device corresponding to the target device specified in step S2 (in this embodiment, It is determined whether or not there is data at the time of the previous inspection for the same device installed at the same place (step S4). Here, it is assumed that this is the first time that the target inspection equipment has been inspected, and that the previous data has not been stored in the memory 3 .

In this case, the process proceeds to step S8, and the server control unit 2 displays a default input form for the target device on the display unit 15 of the mobile terminal 10. FIG. This display is the screen display 40 shown in FIG. In the screen display 40, a drawing 49 of the target device is displayed in the center and a title frame 48 is displayed in the upper part. The title frame 48 displays the device name, the identification number of the device, and the inspection date (current time).

The screen display 40 displays input windows 41, 42, 43, and 44 associated with a specific inspection site of the target device. The relationship between the inspection site and each input window 41, 42, 43, 44 is displayed by connecting them with a line 90 on the screen. These inspection parts are registered in advance as parts to be inspected without exception with respect to the target device specified in step S2, and are stored in the memory 3 of the server 1. FIG.

For example, the input window 41 includes an examination region name display section 41a, an important monitoring check section 41b, an image input section 41c, and a comment input section 41d. The inspection site name display section 41a displays the name of this inspection site from the beginning, but the other important monitoring check section 41b, image input section 41c, and comment input section 41d are blank. As with the input window 41, the input windows 42, 43, and 44 also display an examination site name display section, an important monitoring check section, an image input section, and a comment input section.

The inspection worker inspects each inspection part while referring to the screen display 40 displayed on the display unit 15 of the portable terminal 10 . The inspection is carried out by visual confirmation by an inspector or by using various inspection equipment (not shown). Also, the inspection worker takes an image of the part to be inspected with the imaging unit 13 of the portable terminal 10, inputs and displays the images in the image input units of the input windows 41, 42, 43, and 44, and further inputs a comment in the comment input unit. to display. The screen display 50 in FIG. 3 shows a state in which images and comments have been input.

For example, when inputting an image into the image input section 41c of the input window 41, after tapping the image input section 41c, the image capturing section 13 captures an image of the target inspection site. As a result, the captured image is displayed on the image input unit 41c. Also, by tapping the comment input section 41d of the input window 41, the comment characters can be input through the input section 12. FIG.

If you want to arbitrarily add an inspection site for the target device, tap the location corresponding to the specific inspection site to be added on the screen display 40 . As a result, an input window associated with the added part newly appears on the screen. The input window 45 in the screen display 50 of FIG. 3 is an additional input window, and the relationship with the added inspection site is displayed on the screen by a line 90. FIG. The input window 45 also has an inspection site name display section 45a, an important monitoring check section 45b, an image input section 45c, and a comment input section 45d.

In the added input window 45, the inspection site name display section 45a is blank, so the inspection operator inputs the name of the inspection site. Further, the photographed image and the comment are input to the image input section 45c and the comment input section 45d and displayed.

When the portable terminal 10 receives such inputs, the server control unit 2 takes in the input data each time, and stores and accumulates each input data in the memory 3 (steps S14 and S16). Then, when the inspection worker inputs an inspection end input from the mobile terminal 10, the server control unit 2 receives the input, updates the inspection date and time (current time) to the latest state, and terminates the processing after (step S18).

(Description of inspection data recording process: when there is previous input data)
Next, inspection data recording processing when inspecting the various devices shown in the layout diagram of FIG. 6 for the second time or later will be described using the flowchart of FIG. In the second and subsequent inspections, the inspection worker inputs the identification number of the target device from the input unit 12 of the mobile terminal 10 in order to specify the target device of the inspection.

The server control unit 2 discriminates the input of the designation of this target device (step S2), and discriminates whether or not there is data at the time of the previous inspection for the same device installed in the same place (step S4). In this case, the previous data is recorded in the memory 3 of the server 1 because the examination is the second or later examination. A screen display 50 in FIG. 4 shows the contents of the previous input data.

Since there is the previous data, the server control section 2 proceeds from step S4 to step S6 and determines whether or not the check of the important monitoring check section is recorded in any of the input windows in the previous data. The check of the important monitoring check part is the check entered in the important monitoring check part of the input windows 41, 42, 43, 44 and 45 displayed on the screen display 50 (for example, the important monitoring check part 41b of the input window 41). This is a check that is input and recorded by an inspection worker tapping the focused monitoring check section for inspection parts that should be monitored intensively in future inspections, even though immediate repair or replacement is not required after the inspection.

In this case, as shown in screen display 50, none of input windows 41, 42, 43, 44, and 45 has a check record of the important monitoring check section, so the process proceeds from step S6 to step S10, and the previous The same input window as the data is displayed on the display unit 15 of the mobile terminal 10 as the current input form. This display is screen display 60 in FIG.

In each of the input windows 61, 62, 63, 64, and 65, only the name of the inspection site is displayed in the inspection site name display section, and all other important monitoring check sections, image input sections, and comment input sections are displayed. It is blank. As for the input window 45 added at the time of the previous examination, an input window 65 in which only the name of the examination region is displayed in the examination region name display section 45a is displayed on the screen display 60. FIG.

Then, the inspection operator inspects each inspection site, and inputs photographed images and comments in respective input windows 61 , 62 , 63 , 64 and 65 on the screen display 60 . The server control unit 1 records the input data in the memory 3 (steps S14, S16), and when an end instruction is input, updates the inspection date and time (current time) to the latest state and ends the post-processing ( step S18).

(Description of inspection data recording process: when there is previous input data and there is an intensive monitoring check)
Next, the inspection data recording process in the second and subsequent inspections when the important monitoring check is recorded in the previous data will be described with reference to the flow chart of FIG.

Steps S2 and S4 are the same as those described above, and the server control unit 2 advances from step S4 to step S6 to determine whether any input window in the previous data has a record of checks by the important monitoring check unit. determine whether A screen display 70 in FIG. 5 shows the contents of the previous input data.

A check is recorded and displayed in an important monitoring check portion 71b of an input window 71 appearing on the screen display 70. FIG. That is, at the time of the previous inspection of this target device, the inspected part connected by the input window 71 and the line 90 does not need to be immediately repaired or replaced, but should be monitored intensively in future inspections. After confirming the defect, the inspection worker taps the key monitoring check section 71b to input and record the check. A comment about the defect is also entered in the comment input section 71d. That is, for this target device, at least data indicating that a check has been input and recorded in the intensive monitoring check section 71b and data for displaying a comment about the defect in the comment input section 71d are stored in the memory 3. .

If it is determined that the data indicating that the check has been input and recorded in the focused monitoring check unit 71b for the target equipment exists in the memory 3, the server control unit 2 proceeds from step S6 to step S12, and the current input form is displayed. When the screen display 80 is displayed on the display unit 15 of the mobile terminal 10, the input window 81 corresponding to the input window 71 checked in the important monitoring check unit 71b in the previous data is highlighted with a thick frame 81f.

In the input window 81, the name of the inspection site is displayed in the inspection site name display section 81a and a check is displayed in the focused monitoring check section 81b, but the image input section 81c and comment input section 81d are blank. . In the current input form, since the check is recorded in the focused monitoring check section 81b from the beginning, when the next inspection is performed, the input window corresponding to the input window 81 in the next input form is similarly highlighted. will be

By highlighting the input window corresponding to the input window that has been checked in the key monitoring check part in the previous data with a thick frame, attention is called to the specific inspection part that should be monitored intensively, and it is possible to overlook it. Input errors are easily and reliably prevented. Therefore, it is possible to accurately and efficiently record the results of examinations that are performed repeatedly and continuously.

The inspection operator inspects each inspection site and inputs photographed images and comments in input windows 81 , 82 , 83 , 84 and 85 on screen display 80 . Appropriate measures, such as repair or replacement, are taken according to the results of the inspection for the inspected portion related to the input window 81 that requires intensive monitoring.

[Second embodiment]
Next, a second embodiment of the defect inspection system, defect inspection method, and defect inspection program according to the present application will be described with reference to the flowchart of FIG. The hardware configuration and screen display on the display unit of the mobile terminal are the same as in the first embodiment.

The flow chart (FIG. 7) of the inspection data recording process in this embodiment is also substantially the same as the flow chart (FIG. 2) in the first embodiment, and steps S52, S56, S58, S60, and S62 in the flow chart of FIG. , S64, S66, and S68 correspond to steps S2, S6, S8, S10, S12, S14, S16, and S18 in the flow chart of FIG. 2, and the substantial processing contents are the same. The substantial difference between the flowchart of FIG. 7 in this embodiment and the first embodiment is the processing of step S55.

The following description will focus on the parts that are different from the first embodiment, and will omit the description of the rest. In step S4 of the flowchart in the first embodiment described above, it is determined whether or not there is data at the time of the previous inspection for the target device specified in step S2 and the "same device installed in the same place." Then, in steps S10 and S12, an input window corresponding to the previous data of the same device is displayed on the display unit 15 of the portable terminal 10. FIG.

On the other hand, in step S55 in the present embodiment, as devices corresponding to the target device specified in step S52, "the same device installed in a different place" and "the same type of device" are taken up, and the previous data Determine presence/absence. Here, "the same device installed in a different place" means a device that has the same model, model number, etc. but is installed in a different place. equipment located close to each other, equipment installed in close proximity to each other, equipment used in a similar frequency of use, and each equipment has one or more “different The same device installed at a place or the same type of device are registered and stored in the memory 3 of the server 1 in advance.

In step S55, it is determined whether or not there is previous data for at least one "same device installed in a different location" or "similar device". Then, in step S56, if the priority monitoring check is recorded in either the "same device installed in a different location" or the "same type of device" in the previous data, the process proceeds from step S56 to step S62. The same input window as the previous data in which the important monitoring check is recorded is displayed, and the input window with the important monitoring check is highlighted with a thick frame.

In other words, if the previous data for the same device installed in a different location or for the same type of device contains recorded data from an intensive monitoring check, it is possible that the same problem will occur at the same time for the target device this time. highly sexual. Therefore, by reflecting the important monitoring check of the previous data of the same type of equipment in the input window of the current input form and highlighting it, attention is called to the specific inspection site that should be monitored intensively, and oversight and input Mistakes are easily and reliably prevented. Therefore, it is possible to accurately and efficiently record the results of examinations that are performed repeatedly and continuously.

In step S56, if neither "the same device installed in a different location" nor "the same type of device" in the previous data has an important monitoring check recorded, the process proceeds from step S56 to step S60 and "a different location The same input window as that having the largest number of input windows among the previous data of "same installed equipment" or "similar equipment" is displayed.

First, as in the first embodiment, the presence or absence of the previous data of "the same device installed in the same place" is determined. As in the present embodiment, it may be determined whether or not there is previous data for "the same device installed at a different location" or "the same type of device", and then the processing of the present embodiment may be executed.
