[0017] [First Embodiment] A first embodiment of the aging degradation limit time prediction display system, limit time prediction display method, and limit time prediction display program according to the present application will be described. In this embodiment, an example of predicting and displaying the limit time due to the aging degradation of various devices arranged in an industrial plant will be given. Examples of aging degradation include corrosion of devices.

[0018] A large number of devices are arranged in a predetermined area of the industrial plant. Then, one or two or more inspection workers carry portable terminals respectively to inspect the corrosion of the devices. The inspection worker inputs the inspection results from the portable terminal, and this inspection data is wirelessly transmitted to a server that centrally manages the system.

[0019] (Description of the Hardware Configuration of the Inspection System) The hardware configuration of the inspection system in this embodiment will be described with reference to FIG. 1. The server 1 includes a server control unit 2, a memory 3, and a communication unit 4, and a monitor 5 is connected to the server control unit 2. The portable terminal 10 includes a portable control unit 11, an input unit 12, a photographing unit 13, a memory 14, a display unit 15, and a communication unit 16, and a corrosion inspection device 18 is connected to the portable control unit 11. The server 1 and the portable terminal 10 perform wireless communication via the communication unit 4 and the communication unit 16 respectively to transmit and receive data.

[0020] On the display unit 15 of the portable terminal 10, when performing an inspection, a screen display such as a drawing corresponding to the device to be inspected is performed. The inspection worker inputs various commands and characters through the input unit 12, and uses the photographing unit 13, which is a camera, to photograph an image of the inspection target and display it on the display unit 15. In addition, the corrosion inspection device 18 is used to detect the corrosion of the device, and the detection data is taken into the portable terminal 10. These input data are stored in the memory 14 and transmitted toward the server 1.

[0021] Then, the server 1 stores and accumulates the input data transmitted from the mobile terminal 10 in the memory 3. The server control unit 2 displays a plant map or the like on the monitor 5 and controls the display content. Further, the server control unit 2 executes according to a predetermined program for predictive display processing of the limit time due to the aging deterioration of each device.

[0022] (Inspection of the aging deterioration of each device) As described above, the inspection worker brings the mobile terminal 10 and inspects the corrosion and the like of a large number of devices arranged in a predetermined area of the industrial plant. The inspection is performed for each device. Immediately before performing the inspection, the inspection worker inputs the identification number of the device to be inspected from the input unit 12 of the mobile terminal 10 to specify a specific device.

[0023] In this case, a layout diagram of the devices may be displayed on the display unit 15 of the mobile terminal 10, and the target device may be specified by tapping the icon mark of the specific device. Also, it is possible to read a barcode or QR code (registered trademark) directly attached to the device with a reading device and input the specification of the device.

[0024] The specification of the device by inputting the identification number or the like is transmitted to the server 1, and the server control unit 2 recognizes the specific device to be inspected and transmits inspection data related to this device to the mobile terminal 10. FIG. 4 is a display example of the display unit 15 of the mobile terminal 10, and is a screen display 70 generated based on the inspection data transmitted from the server control unit 2.

[0025] On the screen display 70, a drawing 79 of the target device is displayed in the central part, and a title frame 78 is displayed in the upper part. In the title frame 78, the device name, the identification number of the device, and the inspection date and time are displayed. And on the screen display 70, input windows 71, 72, 73, 74, 75 associated with specific inspection parts of the target device are displayed. The inspection parts and each input window 71, 72, 73, 74, 75 are associated by being connected by a line 90 on the screen. These inspection parts are registered in advance as parts that must be inspected for a specific device to be inspected and are stored in the memory 3 of the server 1.

[0026] For example, the input window 71 includes an inspection site name display section 71a, an image input section 71b, and a comment input section 71c. The name of this inspection site is displayed in the inspection site name display section 71a from the beginning, while the image input section 71b and the comment input section 71c are blank. Note that for the input windows 72, 73, 74, and 75 as well, an inspection site name display section, an image input section, and a comment input section are displayed, similar to the input window 71.

[0027] The inspection operator inspects the degree of corrosion progression of each inspection site while referring to the screen display 70 shown on the display section 15 of the portable terminal 10. The inspection is performed by visual confirmation by the inspection operator or using the corrosion inspection device 18. Also, the inspection operator photographs the inspection site with the photographing section 13 of the portable terminal 10, inputs it into the image input sections of the input windows 71, 72, 73, 74, and 75 for display, and further inputs and displays a comment in the comment input section. In this embodiment, "depth, adjacent wall thickness, remaining wall thickness", which represents the degree of corrosion progression, is displayed in the comment input section.

[0028] For example, when inputting an image into the image input section 71b of the input window 71, the inspection operator taps the image input section 71b and then photographs the target inspection site with the photographing section 13. As a result, the photographed image is displayed in the image input section 71b. Also, the degree of corrosion progression of the inspection site is detected using the corrosion inspection device 18. Data such as the depth of corrosion is taken into the portable control section 11 of the portable terminal 10 and automatically displayed in the columns of "depth, adjacent wall thickness, remaining wall thickness" in the comment input section 71c. Note that if the comment input section 71c of the input window 71 is tapped, comment characters can be input through the input section 12.

[0029] The above inspections are individually performed on a number of devices arranged in a predetermined area of the industrial plant, and all inspection data are taken into the server control unit 2 of the server 1 and recorded in the memory 3. Since corrosion and the like of each device occur over time and then gradually progress as aging deterioration, the inspection of each device is continuously repeated, for example, once a year. And among the inspection data of all devices subject to inspection each time, the elapsed data including data related to corrosion are accumulated in the memory 3 as deterioration elapsed data.

[0030] (Prediction display process for the critical time due to the aging deterioration of the device) Next, a program for the prediction display process of the critical time due to the aging deterioration of the device, which is executed by the server control unit 2, will be described according to the flowchart of FIG. 2. When an instruction to start prediction display is input from the outside to the server 1 (step S2), the server control unit 2 retrieves the deterioration elapsed data of each device from the memory 3 and predicts the critical time of each device based on this deterioration elapsed data (step S4).

[0031] The critical time is the time when the device can no longer maintain a normal state due to aging deterioration and it is considered that measures such as repair or replacement are necessary. For example, the time when corrosion occurs and progresses on the metal surface of the device and the device needs to be replaced or repaired is the critical time for this device.

[0032] In the case of the device shown in the screen display 70 of FIG. 4, corrosion data are recorded at the inspection site indicated by the input window 71. FIG. 5 is a table showing the deterioration elapsed data regarding this inspection site. In this example, three inspection data are recorded. Corrosion was confirmed in the second inspection, and the progress of corrosion was recognized in the third inspection.

[0033] The numerical value in the column of "nearby wall thickness" in the table is the thickness of the inspection site when there is no corrosion. As the corrosion progresses and the "depth" increases, the "remaining wall thickness" decreases. That is, as the numerical value in the column of "remaining wall thickness" decreases, it means that the corrosion is progressing.

[0034] Predict the critical time of the inspection site indicated by the input window 71 of the screen display 70 from the deterioration progress data shown in this Figure 5. Specifically, as shown in Figure 6, graph the relationship between the numerical value of the remaining wall thickness and the number of elapsed years, and obtain the approximate line L1 thereof, and calculate the slope of the approximate line L1 as the deterioration rate (deterioration speed).

[0035] And a predetermined limit value a is set in advance for each inspection site of each device, and the critical time is calculated based on the limit value a and the slope of the approximate line L1. That is, in the graph of Figure 6, the intersection point of the approximate line L1 and the limit reference line L2 indicated by the limit value a is the critical time. In the example of Figure 6, March 2022 is the critical time, and when January 2021 is the current time, it is predicted that the critical time will arrive 1 year and 2 months later. In the present embodiment, the limit value a is set in advance for each inspection site of the inspection object and registered in the memory 3 of the server 1, but a common limit value a may be set for all inspection objects and inspection sites.

[0036] In addition, when there are a plurality of inspection sites for which deterioration progress data is recorded for a specific device, the critical time is predicted for each of those inspection sites. And in the present embodiment, the inspection site where the critical time arrives earliest is picked up, and that time is grasped as the critical time of the device. Note that the critical time of a specific inspection site can also be specified and grasped as the critical time of the device.

[0037] In this way, the critical time is determined for each of all the devices to be inspected. Note that for a device for which no deterioration progress data regarding corrosion is recorded at all, the critical time is grasped as "0".

[0038] Next, the server control unit 2 proceeds to step S6 and classifies each device into a plurality of groups according to the critical time. In the present embodiment, five groups, namely, a "no corrosion" group, a "1 year later" group, a "5 years later" group, a "10 years later" group, and a "20 years later" group are set. The "no corrosion" group is a group into which devices for which deterioration progress data is not recorded and the critical time is "0" are classified.

[0039] And the "after 1 year" group includes devices with a remaining lifespan of less than 1 year and more than 1 year but less than 5 years from now; the "after 5 years" group includes devices with a remaining lifespan of 5 years or more but less than 10 years from now; the "after 10 years" group includes devices with a remaining lifespan of 10 years or more but less than 20 years from now; and the "after 20 years" group includes devices with a remaining lifespan of 20 years or more from now. For the device shown in the screen display 70 of FIG. 4, since the remaining lifespan is 1 year and 2 months from now (FIG. 6), it is classified into the "after 1 year" group.

[0040] Subsequently, the server control unit 2 differentiates each device displayed on the plant map according to the group it belongs to and displays it on the monitor 5 (step S8). FIG. 3 is an example of the plant map displayed on the monitor 5, which shows a number of devices arranged in the area 20 by icon marks 21 and the like. In this embodiment, the icon marks 21 are displayed in different patterns according to the group.

[0041] As shown in FIG. 3, the plant map displayed on the monitor 5 is provided with a group reference frame 25, which shows the pattern of the icon mark of each group, the corresponding number, and the number of years of the group. In the example of FIG. 3, for example, it is displayed that the number of devices classified into the "after 1 year" group is "6", and the installation location of the icon mark 21 of the "after 1 year" group within the area 20 is indicated by the pattern of the icon mark 21. For devices without inspection data, it is displayed as "no corresponding data" in the group reference frame 25, and the icon mark 21 is represented without a pattern.

[0042] By such a display distinguished for each group, it is possible to grasp at a glance the specific limit times of the respective devices arranged in area 20. Therefore, it is possible to easily and surely directly grasp the limit times when each device reaches the limit due to aging deterioration, and it is also possible to easily grasp the arrangement of the devices reaching the limit times within area 20. And when an instruction to end the prediction display is input from the outside to server 1, server control unit 2 ends the prediction display process of the limit times due to the aging deterioration of the devices (step S10).

[0043] In the present embodiment, the icon marks 21 of the devices are displayed in different patterns according to the groups. However, for example, by displaying the icon marks 21 in different colors according to the groups, it is also possible to display the distinction between the groups.

[0044] Also in the present embodiment, all of the distinguished plurality of groups are displayed. However, for example, only one or two or more selected partial groups may be distinguished and displayed. For example, in the display shown in FIG. 3, when the "one year later" group in the group reference frame 25 is selected with a pointer or the like on the screen, only the six icon marks 21 belonging to the "one year later" group in area 20 are displayed with patterns and colors. Further, when the "one year later" group and the "five years later" group are selected, in addition to the "one year later" group, two icon marks 21 belonging to the "five years later" group are displayed with patterns and colors in area 20. In this case, the icon marks 21 of the "one year later" group and the icon marks 21 of the "five years later" group are displayed in different patterns and colors, and the two groups are distinguished.

[0045] Also, a slider bar can be provided in the group reference frame 25, and the group can be selected by sliding this slider bar arbitrarily, and only the icon marks 21 of the selected group can be configured to be distinguished and displayed with patterns and colors.

[0046] [Other Embodiments] In the foregoing embodiments, as an example of the limit time prediction display due to aging deterioration, the display of the limit time due to the aging deterioration of various devices arranged in an industrial plant was exemplified. However, the present invention is not limited thereto, and the limit time prediction display system, the limit time prediction display method, and the limit time prediction display program according to the present application can be applied as long as the aging deterioration of the inspection target is continuously inspected two or more times.

[0047] Further, in the foregoing embodiments, corrosion was cited as an example of aging deterioration. However, the present invention is not limited thereto, and other aging deteriorations can be targeted as long as they are deteriorations that progress over time.

[0048] Furthermore, the screen display of FIG. 3 shown in the foregoing embodiments is an example of an image of the arrangement area on the monitor 5 (display means), and the arrangement and design of the icon marks of the device 21 in the image are not limited thereto, and other arrangements and designs may be adopted.
