[0031] Hereinafter, embodiments of an information processing apparatus, an information processing method, and an information processing program of the present invention will be described in detail based on the drawings. In addition, the information processing apparatus, the information processing method, and the information processing program of the present invention are not limited by the above embodiments.

[0032] [1. Structure of Information Processing System 10]

[0033] First, an overview of the information processing system 10 including the information processing device 100 of the embodiment will be described. Figure 1 This is a diagram showing an example of the information processing system of the embodiment. The information processing device 100 of the information processing system 10 displays information for detecting a malfunction or diagnosing the state of a valve 200 such as a control valve commonly used in petrochemical facilities and the like.

[0034] The information processing device 100 is, for example, a personal computer (PC) or the like connected to the valve 200 through a communication component. The information processing device 100 acquires diagnostic information related to the diagnostic result of the diagnostic object in the valve 200, and displays the diagnostic information and the valve diagram of the valve 200 showing the position of the diagnostic object corresponding to the diagnostic information together.

[0035] For example, the information processing device 100 displays the diagnostic information and the valve diagram of the valve 200 showing where there is a malfunction or a diagnostic object, etc. Additionally, the valve diagram is not particularly limited as long as it shows the valve 200. For example, it can be a real diagram like a design drawing, or a simple diagram that simply shows components such as the diagnostic object.

[0036] In this way, the information processing device 100 displays the diagnostic information and the valve diagram effective for detecting a malfunction or diagnosing the state of the valve 200 together. Therefore, the ease of understanding of the information presented particularly for detecting a malfunction or diagnosing the state of the valve 200 can be improved.

[0037] 〔2. Structure of the information processing device 100〕

[0038] Next, with reference to Figure 2 and Figure 3 the structure of the information processing device 100 will be described. Figure 2 This is a diagram showing an example of the structure of the information processing device of the embodiment. Figure 3 This is a diagram showing an example of the structure of the valve of the embodiment.

[0039] As Figure 2 shown, the information processing device 100 has a storage unit 110, a display unit 120, a communication unit 130, and a control unit 140. Additionally, the structure of the information processing device 100 is not limited to the Figure 2 structure. For example, the display unit 120 of the information processing device 100 can also be located externally.

[0040] The storage unit 110 is implemented by a storage device such as a random access memory (RAM) or a hard disk, and stores data and programs required for various processes performed by the control unit 140.

[0041] The display unit 120 displays the diagnostic information and the valve diagram of the valve 200 that shows the position of the diagnosed object all at once. The display unit 120 is implemented by a monitor of a PC or the like.

[0042] The communication unit 130 is implemented by, for example, a Network Interface Card (NIC) or the like. The communication unit 130 is connected to the valve 200 by wire or wirelessly and performs information transmission and reception.

[0043] The control unit 140 controls the information processing device 100 and is implemented by, for example, using a Central Processing Unit (CPU) or a Micro Processing Unit (MPU) or the like and executing various programs stored in the storage unit 110 with the RAM as the working area. In addition, the control unit 140 is implemented by an integrated circuit such as an Application Specific Integrated Circuit (ASIC) or a Field Programmable Gate Array (FPGA). The control unit 140 includes an acquisition unit 141, a display control unit 142, and a rotation unit 143.

[0044] The acquisition unit 141 acquires diagnostic information related to the diagnostic result of the diagnosed object in the valve 200. For example, the acquisition unit 141 acquires, through a functional unit of an external device that performs defect condition detection or state diagnosis of the diagnosed object or the acquisition unit 141 itself, the following indexes or the like obtained by calculation, detection, etc. using general defect condition detection and diagnosis methods as the diagnosed diagnostic information.

[0045] As an example, the acquisition unit 141 acquires an index of the operator diaphragm of the valve 200 as actuator information related to the diagnostic result of the actuator 201.

[0046] In addition, the acquisition unit 141 acquires, for example, valve stiction as valve shaft information related to the diagnostic result of the valve shaft 202.

[0047] In addition, the acquisition unit 141 acquires, for example, at least one of the breakage of the bellows seal with a signature as a diagnostic index, the deformation of the bellows seal with an increase in friction as a diagnostic index, and the fracture of the bellows seal with a decrease in friction as a diagnostic index, as bellows information related to the diagnostic result of the bellows 202#.

[0048] In addition, the acquisition unit 141 acquires, for example, at least one of a valve scale adhesion, a degradation index of V-Teflon (registered trademark) of the valve 200, a hardening index of the diaphragm of the valve 200, and a degradation index of the thermal cycle of the valve 200 as the inner valve information related to the diagnosis result of the inner valve 203.

[0049] In addition, the acquisition unit 141 acquires, for example, valve hunting as the positioner / controller information related to the diagnosis result of the positioner / controller 204.

[0050] Furthermore, the valve shaft 202 is disposed coaxially with the center line of the actuator 201, for example. The bellows 202# is disposed around the valve shaft 202 that is coaxial with the center line of the actuator 201. The inner valve 203 is disposed substantially coaxially with the center line of the actuator 201. The positioner / controller 204 is disposed at a position different from that of the actuator 201. Thus, in a general direct-acting valve, there is a tendency for the diagnostic information to be concentrated on the center line of the actuator 201, that is, the actuator shaft 205.

[0051] The display control unit 142 displays the diagnostic information acquired by the acquisition unit 141 and the valve 200 showing the position of the diagnostic object specified corresponding to the diagnostic information on the display unit 120. Hereinafter, an example of the display control performed by the display control unit 142 will be described. Figure 1 and is displayed on the display unit 120. Hereinafter, use Figure 4 to illustrate an example of the display control performed by the display control unit 142.

[0052] Figure 4 is a diagram showing an example of the display of the diagnostic information and the valve diagram. As Figure 4 illustrated, the display control unit 142 displays the diagnostic information 300 and the valve diagram 400 on the display unit 120 together. The valve diagram 400 is specified by establishing a correspondence between the position of the diagnostic object corresponding to each diagnostic information 300 and each diagnostic information 300 through a lead wire.

[0053] For example, the display control unit 142 displays the following diagnostic information 300 of (I) to (IV). At this time, the display control unit 142 can additionally display, for example, defect condition information indicating a defect condition represented by at least one of characters, colors, and symbols, information indicating whether the diagnosis result is good, etc. for the following (I) to (IV). As an example, the display control unit 142 can display Figure 4 around the actuator information 301 of, for example, defect condition information such as the text "defect condition exists" or a red exclamation mark indicating that the actuator 201 is in a defect condition.

[0054] (I) Actuator information 301

[0055] (II) Valve shaft information 302

[0056] (III) Inner valve information 303

[0057] (IV) Locator / Controller Information 304

[0058] Meanwhile, the display control unit 142 displays a valve diagram 400 that specifies the positions of the following (i) to (iv) by corresponding to the above (I) to (IV) respectively using leads.

[0059] (i) The position of the actuator 201 pointing to the upper end of the valve 200

[0060] (ii) The position of the valve shaft 202 coaxial with the center line of the actuator 201

[0061] (iii) The position of the inner valve 203 pointing to the lower end of the valve shaft 202

[0062] (iv) The position of the locator / controller 204 pointing to one end of the valve 200

[0063] The display form and quantity of the diagnostic information 300 are not limited to Figure 4 the structure. In addition, the diagnostic information 300 may further include bellows information as the fifth diagnostic information, for example, and the valve shaft information 302 may also include bellows information. The quantity of the diagnostic information 300 is, for example, 10 or less, whereby the number of characters can be reduced and it is easy to view.

[0064] Return to Figure 2 the description. When the rotation unit 143 receives an instruction to rotate the valve diagram displayed by the display control unit 142, it rotates the valve diagram. For example, the rotation unit 143 can easily prompt the user with specific components such as hidden diagnostic objects by rotating the valve diagram in the state displayed on the display control unit 142. In addition, the rotation unit 143 can also process the rotation of the valve diagram as an internal process, and omit the display of the rotating valve diagram in the display control unit 142 and display the rotated valve diagram.

[0065] Hereinafter, using Figure 5 and Figure 6 an example of the rotation of the valve diagram performed by the rotation unit 143 will be described. Figure 5 is a diagram showing an example of rotation with the actuator shaft as the rotation axis. Figure 6 is a diagram showing an example of rotation with the actuator shaft when the valve diagram is inclined as the rotation axis.

[0066] For example, when receiving an instruction to rotate the valve diagram 400 by clicking a rotation button or the like of the user interface (UI) displayed on the display unit 120, the rotation unit 143 rotates the valve diagram 400 with the center line of the actuator of the valve diagram 400, that is, the actuator shaft 401 as the rotation axis.

[0067] As an example, the rotating unit 143 rotates the valve diagram 400 displayed in the normal direction, i.e., Figure 5 the left diagram in, by 180° about the actuator shaft 401 as the rotation axis, so as to become Figure 5 the right diagram in. In this case, the rotating unit 143 rotates, for example, in the state of displaying the valve diagram 400 about the actuator shaft 401 which is the center line of the pneumatic diaphragm and is coaxial with the valve shaft of a general direct-acting valve as the rotation axis.

[0068] As Figure 5 shown, if there are component parts such as a positioner / controller only on one side of the valve diagram 400, the actuator shaft 401 and the centroid axis 402 do not coincide. Therefore, when rotating about the centroid axis 402 as the rotation axis, all the diagnostic information 300 must be moved. In contrast, since the rotating unit 143 rotates the valve diagram 400 about the actuator shaft 401 as the rotation axis, it is only necessary to move the positioner / controller information 304 in the diagnostic information 300 along with the rotation, and the display positions of the other diagnostic information 300 can be fixed.

[0069] As Figure 6 shown, for example, due to certain reasons such as the situation of the display space, when the valve diagram 400 is displayed obliquely, the effect of fixing the display positions of the other diagnostic information 300 by rotating about the actuator shaft 401 as the rotation axis becomes more significant. That is, the rotating unit 143 rotates the obliquely displayed valve diagram 400 about the actuator shaft 401 as the rotation axis, whereby the amount of movement of the diagnostic information 300 can be particularly reduced compared with the case of rotating about the centroid axis 402 as the rotation axis.

[0070] In addition, in Figure 5 and Figure 6 , the rotation direction is the counterclockwise direction indicated by the arrowhead of the arrow, and the rotation angle is 180°. However, the rotation direction and the rotation angle are not particularly limited and can be set arbitrarily.

[0071] [3. Processing Flow of the Information Processing Apparatus 100]

[0072] Next, an example of the processing flow of the information processing apparatus 100 based on the embodiment will be described using Figure 7 . Figure 7 is a flowchart showing an example of the processing flow of the information processing apparatus according to the embodiment. In addition, the following respective processes can also be executed in a different order. Also, in the following respective processes, for example, there may be processes such as S103 and S104 omitted.

[0073] The acquisition unit 141 of the information processing apparatus 100 acquires diagnostic information related to the diagnostic result of a diagnostic object in the valve 200 (S101). Then, the display control unit 142 displays together the diagnostic information acquired by the acquisition unit 141 and the valve diagram of the valve 200 that shows the position of the diagnostic object corresponding to the diagnostic information (S102).

[0074] After that, when the rotation unit 143 receives an instruction to rotate the valve diagram displayed by the display control unit 142 (S103; Yes), the rotation unit 143 rotates the valve diagram (S104). For example, the rotation unit 143 rotates the valve diagram about the center line of the actuator of the valve diagram, that is, the actuator axis. After S104, or when the rotation unit 143 does not receive an instruction to rotate (S103; No), the information processing apparatus 100 ends the process.

[0075] [4. Effects of the Embodiment]

[0076] The information processing apparatus 100 of the embodiment includes an acquisition unit 141 and a display control unit 142. The acquisition unit 141 acquires diagnostic information related to the diagnostic result of a diagnostic object in the valve 200. The display control unit 142 displays together the diagnostic information acquired by the acquisition unit 141 and the valve diagram of the valve 200 that shows the position of the diagnostic object corresponding to the diagnostic information.

[0077] In this way, the information processing apparatus 100 displays the diagnostic information and the valve diagram that is effective for the detection of a malfunction or the state diagnosis of the valve 200 together, so that the understandability of the information presented particularly for the detection of a malfunction or the state diagnosis of the valve 200 can be improved.

[0078] In addition, the information processing apparatus 100 further includes a rotation unit 143 that rotates the valve diagram when it receives an instruction to rotate the valve diagram displayed by the display control unit 142. Here, for the position of a malfunction or a diagnostic object, since it is located inside the valve 200, a sectional view is preferably used. However, depending on the components, there are many cases where some other components are hidden, which can sometimes be a major cause of confusion.

[0079] On the other hand, since the number of parts of the valve 200 is not as large as that of, for example, an automobile, the information processing apparatus 100 can change the section of the valve 200 or change the viewing point by dynamically rotating and displaying the valve diagram, thereby substantially eliminating the situation where a specific component is hidden.

[0080] In addition, the rotation unit 143 rotates the valve diagram about the center line of the actuator of the valve diagram, that is, the actuator axis. Here, when the valve diagram is rotated about an arbitrary rotation axis, the position of the diagnostic information sometimes deviates from the position of the corresponding diagnostic object. Therefore, the diagnostic information must also be displayed while being appropriately moved along with the rotation.

[0081] On the other hand, diagnostic information including malfunction information, for example, tends to concentrate on the center line of the pneumatic diaphragm, that is, the actuator shaft coaxial with the valve shaft of a general direct-acting valve. Therefore, by rotating with the actuator shaft rather than the centroid axis of the valve diagram or the like as the rotation axis, the information processing device 100 is less likely to shift the display of diagnostic information including malfunction information, etc., and thus can fix the display position of the diagnostic information as much as possible. As a result, the information processing device 100 can further improve the ease of understanding of the information particularly presented for malfunction detection or state diagnosis of the valve 200.

[0082] In addition, the rotating unit 143 rotates the valve diagram displayed obliquely with the actuator shaft as the rotation axis. Thus, compared with the case of rotating with the centroid axis that requires the display position of the diagnostic information to be greatly moved compared to normal, the information processing device 100 can particularly reduce the movement amount of the diagnostic information.

[0083] 〔5. Hardware Structure〕

[0084] The information processing device 100 of the embodiment is implemented, for example, by Figure 8 a computer 1000 having the structure shown. Figure 8 FIG. is a diagram showing an example of the hardware structure. The computer 1000 has a configuration in which a CPU 1100, a RAM 1200, a read-only memory (ROM) 1300, an auxiliary storage device 1400, a communication interface (interface, I / F) 1500, and an input / output I / F 1600 are connected via a bus 1800.

[0085] The CPU 1100 controls each part based on programs stored in the ROM 1300 or the auxiliary storage device 1400. The communication I / F 1500 transmits and receives data between the CPU 1100 and other devices via a prescribed communication network.

[0086] The CPU 1100 controls output devices such as a display or a printer, and input / output devices 1700 such as a keyboard or a mouse via the input / output I / F 1600. For example, the CPU 1100 acquires data from the input / output devices 1700 via the input / output I / F 1600 and outputs the generated data to the input / output devices 1700. In addition, the CPU 1100 realizes the functions of the control unit 140 by executing programs loaded onto the RAM 1200.
