Description

The present application relates to a system for predicting and displaying the time when an object reaches its limit due to deterioration over time, a method for predicting and displaying the time when an object reaches its limit due to deterioration over time, and a program for predicting and displaying the time when an object reaches its limit due to deterioration over time.

One technology for inspecting objects that deteriorate over time and displaying the inspection results is the deterioration management system for plated structures that uses map information, disclosed in Patent Document 1 below. This technology utilizes a map information system to display topographical conditions, surrounding environment, deterioration diagnosis results, etc. on a map in the deterioration management of zinc-plated electricity transmission towers and the like. This allows for the progress of deterioration to be predicted in a short period of time, taking into account regional characteristics.

In other words, this system uses a transmission tower image diagnostic system 1 and a map information system 2 to display the locations of transmission towers constructed in various locations and the deterioration diagnosis results using color-coded markers on a map.

Then, towers that can be considered to have roughly the same corrosion environment are selected using the topographical conditions and surrounding environment of the tower construction site based on map information, or the tower's climate data and environmental measurement data, and the corrosion rate of the selected area is calculated through statistical processing based on the deterioration diagnosis results and age of the selected towers.

The corrosion rate of each selected area is used to create a corrosion map in which areas are color-coded according to their corrosive environment. In addition, to improve the accuracy of the corrosion map, the magnitude of the corrosion rate is color-coded and displayed with a marker on the map.

[First embodiment]
A first embodiment of the system, method, and program for predicting and displaying the limit time due to aging degradation according to the present application will be described. In this embodiment, a prediction display of the limit time due to aging degradation of various devices installed in an industrial plant is illustrated. Aging degradation includes corrosion of the devices.

A large number of devices are placed in a specific area of an industrial plant. One or more inspection workers each bring a mobile device and inspect the devices for corrosion, etc. The inspection workers input the inspection results into the mobile device, and this inspection data is wirelessly transmitted to a server that centrally manages the system.

(Explanation 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 mobile terminal 10 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, and a corrosion inspection device 18 is connected to the mobile control unit 11. The server 1 and the mobile terminal 10 communicate wirelessly via the communication units 4 and 16, respectively, to transmit and receive data.

When an inspection is performed, the display unit 15 of the mobile terminal 10 displays a screen containing diagrams and other images corresponding to the equipment being inspected, and the inspection worker inputs various commands and characters through the input unit 12, takes an image of the inspection target using the photographing unit 13, which is a camera, and displays it on the display unit 15. In addition, corrosion of the equipment is detected using a corrosion inspection device 18, and the detection data is imported into the mobile terminal 10. This input data is stored in the memory 14 and transmitted to the server 1.

Then, the server 1 stores the input data sent from the mobile terminal 10 in the memory 3. The server control unit 2 displays the plant map and the like on the monitor 5, and controls the display content. The server control unit 2 also executes a predetermined program for predicting and displaying the time when each piece of equipment will reach its limit due to deterioration over time.

(Inspection of aging of each device)
As described above, an inspection worker carries the mobile terminal 10 and inspects corrosion and the like of a large number of devices arranged in a specified area of an industrial plant. Inspections are performed for each device, and the inspection worker inputs the identification number of the device to be inspected into the input unit 12 of the mobile terminal 10 immediately before carrying out the inspection, thereby specifying the specific device.

In this case, the display unit 15 of the mobile terminal 10 may be configured to display a layout diagram of the devices, and the icon mark of a specific device may be tapped to input the designation of the target device. Also, a barcode or QR code (registered trademark) attached directly to the device may be read by a reading device to input the designation of the device.

The device specified by inputting an identification number or the like is sent 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. Figure 4 shows an example of the display on the display unit 15 of the mobile terminal 10, which is a screen display 70 that is generated based on the inspection data transmitted from the server control unit 2.

On screen display 70, a drawing 79 of the target device is displayed in the center, and a title frame 78 is displayed at the top. The device name, device identification number, and inspection date and time are displayed in title frame 78. Then, on screen display 70, input windows 71, 72, 73, 74, and 75 associated with specific inspection areas of the target device are displayed. The inspection areas and each input window 71, 72, 73, 74, and 75 are connected on the screen by lines 90 to show the association. These inspection areas are registered in advance as areas that must be inspected for the specific device to be inspected, and are stored in memory 3 of server 1.

For example, input window 71 has an examination area name display section 71a, an image input section 71b, and a comment input section 71c. The name of the examination area is displayed in examination area name display section 71a from the beginning, but image input section 71b and comment input section 71c are blank. Note that input windows 72, 73, 74, and 75 also display an examination area name display section, an image input section, and a comment input section, just like input window 71.

The inspection worker inspects the degree of corrosion progress of each inspection area while referring to the screen display 70 displayed on the display unit 15 of the mobile terminal 10. The inspection is performed by the inspection worker through visual inspection and by using the corrosion inspection device 18. The inspection worker also photographs the inspection area with the photographing unit 13 of the mobile terminal 10, inputs the images into the image input units of the input windows 71, 72, 73, 74, and 75 for display, and further inputs comments into the comment input unit for display. In this embodiment, the "depth, adjacent wall thickness, and remaining wall thickness," which indicate the degree of corrosion progress, are displayed in the comment input unit.

For example, when inputting an image into the image input section 71b of the input window 71, the inspection worker taps the image input section 71b and then photographs the target inspection area with the photographing unit 13. This causes the photographed image to be displayed in the image input section 71b. In addition, the corrosion inspection device 18 is used to detect the degree of corrosion progress in the inspection area. Data such as the corrosion depth is imported into the mobile control unit 11 of the mobile terminal 10 and automatically displayed in the "depth, adjacent wall thickness, remaining wall thickness" fields of the comment input section 71c. Note that by tapping the comment input section 71c of the input window 71, the text of the comment can be entered via the input unit 12.

Inspections like the above are carried out individually for many devices arranged in a specified area of the industrial plant, and all inspection data is imported into the server control unit 2 of the server 1 and recorded in memory 3. Since corrosion and other issues in each device occur over time and are a type of aging deterioration that progresses gradually thereafter, inspections of each device are continuously and repeatedly carried out, for example, once a year. Then, from the inspection data for each inspection of all the devices that are inspected, progress data that includes data on corrosion is stored in memory 3 as deterioration progress data.

(Prediction and display of equipment reaching its limit due to aging)
Next, the program for predicting and displaying the end of life due to aging of the equipment, which is executed by the server control unit 2, will be described with reference to the flowchart in Fig. 2. When an instruction to start predictive display is input from the outside to the server 1 (step S2), the server control unit 2 retrieves the deterioration progress data of each equipment from the memory 3 and predicts the end of life of each equipment based on this deterioration progress data (step S4).

The limit is the time when the equipment can no longer maintain its normal condition due to deterioration over time, and repair, replacement, or other measures are considered necessary. For example, the limit is the time when corrosion begins to form and progress on the metal surface of the equipment, making it necessary to repair or replace it.

In the case of the equipment shown in screen display 70 of Figure 4, corrosion data is recorded in the inspection area shown in input window 71. Figure 5 is a table showing the deterioration progress data for this inspection area. In this example, data from three inspections is recorded, with corrosion being confirmed in the second inspection and the progression of corrosion being noted in the third inspection.

The value in the "Nearby wall thickness" column in the table is the thickness of the inspection area when there is no corrosion, and as corrosion progresses and the "depth" increases, the "remaining wall thickness" decreases. In other words, the smaller the value in the "remaining wall thickness" column, the more corrosion has progressed.

The deterioration progress data shown in Figure 5 is used to predict the limit time of the inspection area shown in the input window 71 on the screen display 70. Specifically, as shown in Figure 6, the relationship between the remaining thickness value and the number of years passed is graphed to obtain an approximation line L1, and the slope of the approximation line L1 is calculated as the deterioration rate (deterioration speed).

A preset limit value a is preset for each examination site of each device, and the limit time is calculated based on the limit value a and the slope of the approximation line L1. That is, in the graph of FIG. 6, the intersection of the approximation line L1 and the limit reference line L2 indicated by the limit value a is the limit time. In the example of FIG. 6, the limit time is March 2022, and if January 2021 is the present, it is predicted that the limit time will arrive in one year and two months. In this embodiment, the limit value a is preset for each examination site of the examination subject and registered in the memory 3 of the server 1, but a common limit value a may be set for all examination subjects and examination sites.

If there are multiple inspection sites for which deterioration progress data is recorded for a particular device, the limit time is predicted for each inspection site. In this embodiment, the inspection site for which the limit time will arrive earliest is selected, and that time is recognized as the limit time for that device. It is also possible to specify a particular inspection site and recognize its limit time as the limit time for that device.

In this way, the limit time is determined for each piece of equipment being inspected. Note that for equipment for which no corrosion-related deterioration data has been recorded, the limit time is taken to be "0."

Then, the server control unit 2 proceeds to step S6 and classifies each device into a number of groups according to its limit time. In this embodiment, five groups are set: a "no corrosion" group, a "one year later" group, a "five years later" group, a "ten years later" group, and a "20 years later" group. The "no corrosion" group is a group into which devices for which no deterioration progress data has been recorded and whose limit time is "0" are classified.

The "1 year later" group is made up of equipment whose limit date is less than 1 year and 1 to 5 years from the present, the "5 years later" group is made up of equipment whose limit date is 5 to 10 years from the present, the "10 years later" group is made up of equipment whose limit date is 10 to 20 years from the present, and the "20 years later" group is made up of equipment whose limit date is 20 years or more from the present. In the case of the equipment shown on screen display 70 in Figure 4, the limit date is 1 year and 2 months from the present (Figure 6), so it is classified into the "1 year later" group.

Next, the server control unit 2 displays each device displayed on the plant map on the monitor 5, distinguishing them according to the group to which they belong (step S8). Figure 3 is an example of a plant map displayed on the monitor 5, in which a large number of devices arranged in the area 20 are represented by icon marks 21, etc. In this embodiment, the icon marks 21 are displayed in different patterns depending on the group.

As shown in Figure 3, the plant map displayed on the monitor 5 has a group reference frame 25, which shows the pattern of the icon mark for each group, the number of items, and the number of years for the group. In the example of Figure 3, for example, it is displayed that the number of devices classified into the "one year later" group is "6", and the location of the icon mark 21 for the "one year later" group within the area 20 is shown by the pattern of the icon mark 21. For devices without inspection data, "no applicable data" is displayed in the group reference frame 25, and the icon mark 21 is displayed without a pattern.

By displaying each group in this way, it is possible to grasp at a glance the specific time when each piece of equipment located within area 20 will reach its limit due to deterioration over time. This makes it possible to easily, reliably and directly grasp the time when each piece of equipment will reach its limit due to deterioration over time, and further makes it possible to easily grasp the location within area 20 of the equipment that will reach its limit. Then, when an instruction to end the predicted display is input from outside to server 1, server control unit 2 ends the process of predicting the time when the equipment will reach its limit due to deterioration over time (step S10).

In this embodiment, the icon marks 21 of the devices are displayed in different patterns depending on the group, but it is also possible to distinguish between groups by, for example, displaying the icon marks 21 in different colors depending on the group.

In this embodiment, all of the multiple distinguished groups are displayed, but for example, only one or more arbitrarily selected groups may be displayed with distinction. For example, in the display shown in FIG. 3, when the "1 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 "1 year later" group are displayed in area 20 with patterns and colors. Furthermore, when the "1 year later" group and the "5 years later" group are selected, in addition to the "1 year later" group, two icon marks 21 belonging to the "5 years later" group are displayed in area 20 with patterns and colors. In this case, the icon marks 21 of the "1 year later" group and the icon marks 21 of the "5 years later" group are displayed with different patterns and colors to distinguish between the two groups.

Also, a slider bar can be displayed in the group reference frame 25, and a group can be selected by sliding the slider bar as desired, so that only the icon mark 21 of the selected group is displayed with a distinctive pattern or color.
