[Technical Field]

[0001] The present invention relates to an information processing device, an information processing method, and an information processing program. [Background technology]

[0002] Valves such as control valves used in petrochemical plants and the like require particular attention to safety, and therefore undergo regular maintenance. To improve the efficiency of this maintenance work, technologies have been proposed for detecting valve stick-slip (see, for example, Patent Document 1), detecting valve hunting (see, for example, Patent Document 2), detecting valve scaling (see, for example, Patent Document 3), and the like. These technologies also include, for example, functional units that present information for detecting valve malfunctions and diagnosing the condition of the valve.

[0004] However, conventional technologies may not be able to improve the understandability of information presented for valve malfunction detection and condition diagnosis. For example, when detecting valve malfunctions or diagnosing a condition, information needs to be presented appropriately, but valve users, such as employees of plant owner companies, are usually unfamiliar with the structure and operation of valves, and therefore may not be able to easily understand the presented information. [Means for solving the problem]

[0005] In order to solve the above-mentioned problems, the information processing device of the present invention has an acquisition unit that acquires diagnostic information regarding the diagnostic results of a diagnostic object in a valve, and a display control unit that displays, together with the diagnostic information acquired by the acquisition unit, a diagram of the valve showing the valve in which the position of the diagnostic object corresponding to the diagnostic information has been identified. [Effects of the Invention]

[0008] Hereinafter, an information processing device, an information processing method, and an information processing program according to an embodiment of the present invention will be described in detail with reference to the drawings. Note that the information processing device, the information processing method, and the information processing program according to the present invention are not limited to these embodiments.

[0009] 1. Configuration of Information Processing System 10 First, an overview of an information processing system 10 including an information processing device 100 according to an embodiment will be described. Fig. 1 is a diagram showing an example of an information processing system according to an embodiment. The information processing device 100 of the information processing system 10 displays information for detecting malfunctions and diagnosing the status of a valve 200, such as a control valve that is generally used in a petrochemical plant or the like.

[0010] The information processing device 100 is, for example, a PC (Personal Computer) connected to the valve 200 via a communication means. The information processing device 100 acquires diagnostic information relating to the diagnostic results of the diagnostic object in the valve 200, and displays, together with the diagnostic information, a diagram of the valve 200 in which the position of the diagnostic object corresponding to the diagnostic information has been identified.

[0011] For example, the information processing device 100 displays a diagram of the valve 200 together with the diagnostic information, with the location of the malfunction, the diagnostic target, etc. added. The diagram of the valve is not particularly limited as long as it is a diagram showing the valve 200, and may be, for example, a realistic diagram such as a design drawing, or a schematic diagram that simply represents the components of the diagnostic target, etc.

[0012] In this way, the information processing device 100 displays a diagram of the valve that is effective for detecting malfunctions and diagnosing the condition of the valve 200 along with the diagnostic information, thereby improving the ease of understanding of the information presented, particularly for detecting malfunctions and diagnosing the condition of the valve 200.

[0013] 2. Configuration of Information Processing Device 100 Next, the configuration of the information processing device 100 will be described with reference to Fig. 2 and Fig. 3. Fig. 2 is a diagram showing an example of the configuration of the information processing device according to the embodiment. Fig. 3 is a diagram showing an example of the configuration of a valve according to the embodiment.

[0014] 2, the information processing device 100 includes a storage unit 110, a display unit 120, a communication unit 130, and a control unit 140. Note that the configuration of the information processing device 100 is not limited to the configuration in FIG. 2, and for example, the display unit 120 of the information processing device 100 may be external.

[0015] The storage unit 110 is realized by a storage device such as a RAM (Random Access Memory) or a hard disk, and stores data and programs required for various processes by the control unit 140.

[0016] The display unit 120 displays the diagnostic information and a diagram of the valve 200, the position of which is to be diagnosed, as well as the diagnostic information. The display unit 120 is realized by a PC monitor or the like.

[0017] The communication unit 130 is realized by, for example, a network interface card (NIC), etc. The communication unit 130 is connected to the valve 200 by wire or wirelessly, and transmits and receives information.

[0018] The control unit 140 controls the information processing device 100, and is realized by, for example, a CPU (Central Processing Unit) or an MPU (Micro Processing Unit) executing various programs stored in the storage unit 110 using RAM as a work area. The control unit 140 is also realized by, for example, an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array). The control unit 140 has an acquisition unit 141, a display control unit 142, and a rotation unit 143.

[0019] The acquisition unit 141 acquires diagnostic information related to the diagnostic results of the diagnostic target in the valve 200. For example, the acquisition unit 141 acquires, as the diagnosed diagnostic information, the following indicators and the like that are calculated, detected, etc. using a general fault detection and diagnostic method by the acquisition unit 141 itself or by a functional unit of an external device that detects faults and diagnoses the state of the diagnostic target.

[0020] As an example, the acquisition unit 141 acquires an index of the actuator diaphragm of the valve 200 as actuator information related to the diagnosis result of the actuator 201.

[0021] The acquisition unit 141 also acquires, for example, valve stick-slip as valve stem information related to the diagnosis result of the valve stem 202.

[0022] In addition, the acquisition unit 141 acquires, as bellows information regarding the diagnostic results of the bellows 202#, at least one of, for example, damage to the bellows seal using a signature as a diagnostic indicator, deformation of the bellows seal using an increase in friction as a diagnostic indicator, and rupture of the bellows seal using a decrease in friction as a diagnostic indicator.

[0023] In addition, the acquisition unit 141 acquires, as inner valve information relating to the diagnosis results of the inner valve 203, for example, at least one of the following: valve scale adhesion, a deterioration index of the V Teflon (registered trademark) of the valve 200, a hardening index of the diaphragm of the valve 200, and a deterioration index of the heat cycle of the valve 200.

[0024] Furthermore, the acquisition unit 141 acquires, for example, valve hunting as a positioner / control related to the diagnostic result of the positioner / control 204.

[0025] The valve shaft 202 is provided, for example, coaxially with the center line of the actuator 201. The bellows 202# is provided around the valve shaft 202, which is coaxial with the center line of the actuator 201. The inner valve 203 is provided approximately coaxially with the center line of the actuator 201. The positioner / control 204 is provided at a location separate from the actuator 201. As such, in a typical direct acting valve, diagnostic information tends to be concentrated on the actuator shaft 205, which is the center line of the actuator 201.

[0026] The display control unit 142 causes the display unit 120 to display, together with the diagnostic information acquired by the acquisition unit 141, a diagram of the valve indicating the valve 200 for which the position of the diagnostic target corresponding to the diagnostic information has been identified. An example of display control by the display control unit 142 will be described below with reference to FIG. 4.

[0027] 4 is a diagram showing an example of the display of diagnostic information and a diagram of a valve. As shown in the example of Fig. 4, the display control unit 142 causes the display unit 120 to display, together with the above-mentioned diagnostic information 300, a diagram 400 of a valve in which the positions of the diagnostic targets corresponding to each piece of diagnostic information 300 are associated with each piece of diagnostic information 300 by leader lines.

[0028] For example, the display control unit 142 displays the following diagnostic information 300 (I) to (IV). At that time, the display control unit 142 can additionally display information indicating the pass / fail of the diagnostic result, such as malfunction information indicating a malfunction using at least one of characters, colors, and symbols, in addition to the following (I) to (IV). As an example, the display control unit 142 can further display malfunction information, such as the characters "Malfunction" or a red exclamation mark indicating that the actuator 201 is malfunctioning, around the actuator information 301 in FIG. 4. (I) Actuator Information 301 (II) Valve stem information 302 (III) Internal Affairs Information 303 (IV) Positioner / Controller 304

[0029] At the same time, the display control unit 142 displays a diagram 400 of the valve in which the positions of the following (i) to (iv) are identified by being associated with each of the above (I) to (IV) by leading lines. (i) Position of actuator 201 pointing to the top of valve 200 (ii) The position of the valve stem 202 that is coaxial with the center line of the actuator 201 (iii) Position of the inner valve 203 pointing to the lower end of the valve stem 202 (iv) The position of the positioner / control 204 pointing to one end of the valve 200

[0030] The display mode and number of pieces of diagnostic information 300 are not limited to the configuration in Fig. 4. Furthermore, the diagnostic information 300 may further include bellows information as a fifth piece of diagnostic information, or the valve stem information 302 may include bellows information. By limiting the number of pieces of diagnostic information 300 to, for example, 10 or less, the number of characters can be reduced and the information can be made easier to read.

[0031] Returning to the explanation of Fig. 2, when the rotation unit 143 receives an instruction to rotate the valve diagram displayed by the display control unit 142, the rotation unit 143 rotates the valve diagram. For example, by rotating the valve diagram while it is displayed on the display control unit 142, the rotation unit 143 can make it easier to present a specific component, such as a hidden diagnostic target, to the user. Furthermore, by treating the rotation of the valve diagram as an internal process, the rotation unit 143 can cause the display control unit 142 to omit displaying the valve diagram while it is rotating and display the valve diagram after it has been rotated.

[0032] An example of rotation of the valve illustration by the rotation unit 143 will be described below with reference to Figures 5 and 6. Figure 5 is a diagram showing an example of rotation around the actuator axis as the rotation axis. Figure 6 is a diagram showing an example of rotation around the actuator axis as the rotation axis when the valve illustration is displayed at an angle.

[0033] For example, when an instruction to rotate the valve diagram 400 is received by clicking a UI (User Interface) such as a rotation button displayed on the display unit 120, the rotation unit 143 rotates the valve diagram 400 around the actuator axis 401, which is the center line of the actuator of the valve diagram 400, as the rotation axis.

[0034] As an example, the rotation unit 143 rotates the left diagram of Fig. 5, which is a diagram 400 of the valve displayed from the normal direction, by 180° around the actuator shaft 401 as the rotation axis so that it becomes the display of the right diagram of Fig. 5. In this case, the rotation unit 143 rotates the diagram 400 of the valve while it is displayed, around 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.

[0035] 5, if components such as a positioner / control are present on only one side of a valve diagram 400, the actuator axis 401 and the centroid axis 402 do not coincide, and therefore, when the valve diagram 400 is rotated around the centroid axis 402, all of the diagnostic information 300 must be moved. In contrast, the rotating unit 143 rotates the valve diagram 400 around the actuator axis 401 as the rotation axis, so that of the diagnostic information 300, only the positioner / control 304 needs to move in conjunction with this rotation, and the display positions of the other diagnostic information 300 can be fixed.

[0036] 6, when the valve diagram 400 is displayed at an angle due to some reason, such as limited display space, the effect of rotating the other diagnostic information 300 around the actuator axis 401, that is, being able to fix the display position of the other diagnostic information 300, becomes even more pronounced. In other words, by rotating the valve diagram 400 displayed at an angle around the actuator axis 401, the rotation unit 143 can particularly reduce the amount of movement of the diagnostic information 300 compared to when rotating around the centroid axis 402.

[0037] In Figures 5 and 6, the rotation direction is counterclockwise as indicated by the arrow, and the rotation angle is 180°, but the rotation direction and rotation angle are not particularly limited and can be set arbitrarily.

[0038] 3. Processing Procedure of Information Processing Device 100 Next, an example of a processing procedure by the information processing device 100 according to the embodiment will be described with reference to Fig. 7. Fig. 7 is a flowchart showing an example of a processing procedure by the information processing device according to the embodiment. Note that the following processes can also be executed in a different order. Also, some of the following processes, such as S103 and S104, may be omitted.

[0039] The acquisition unit 141 of the information processing device 100 acquires diagnostic information relating to the diagnostic results of the diagnostic object in the valve 200 (S101). Then, the display control unit 142 displays, together with the diagnostic information acquired by the acquisition unit 141, a diagram of the valve showing the valve 200 in which the position of the diagnostic object corresponding to the diagnostic information has been identified (S102).

[0040] Thereafter, when the rotation unit 143 receives an instruction to rotate the valve illustration displayed by the display control unit 142 (S103; Yes), the rotation unit 143 rotates the valve illustration (S104). For example, the rotation unit 143 rotates the valve illustration around the actuator axis, which is the center line of the actuator in the valve illustration, as the rotation axis. After S104, or when the rotation unit 143 does not receive an instruction to rotate (S103; No), the information processing device 100 ends the processing.

[0041] 4. Effects of the embodiment The information processing device 100 according to the embodiment includes an acquisition unit 141 and a display control unit 142. The acquisition unit 141 acquires diagnostic information relating to the diagnostic results of the diagnostic object in the valve 200. The display control unit 142 displays, together with the diagnostic information acquired by the acquisition unit 141, a diagram of the valve showing the valve 200 in which the position of the diagnostic object corresponding to the diagnostic information has been identified.

[0042] In this way, the information processing device 100 displays a diagram of the valve that is effective for detecting malfunctions and diagnosing the condition of the valve 200 along with the diagnostic information, thereby improving the ease of understanding of the information presented, particularly for detecting malfunctions and diagnosing the condition of the valve 200.

[0043] The information processing device 100 also has a rotation unit 143 that rotates the diagram of the valve when an instruction to rotate the diagram of the valve displayed by the display control unit 142 is received. Here, since the location of the malfunction or the diagnosis target is a position inside the valve 200, it is preferable to use a cross-sectional view, but depending on the component, it is quite likely that one component will be hidden by another component, which can be confusing.

[0044] On the other hand, since the valve 200 does not have as many parts as, for example, an automobile, the information processing device 100 can dynamically rotate and display the diagram of the valve, thereby changing the cross section of the valve 200 or changing the viewpoint, thereby generally eliminating the problem of certain components being hidden.

[0045] Furthermore, the rotation unit 143 rotates the diagram of the valve around the actuator axis, which is the center line of the actuator in the diagram of the valve. Here, when the diagram of the valve is rotated around an arbitrary rotation axis, the position of the diagnostic information may be shifted from the position of the corresponding diagnostic target, so in some cases the diagnostic information must also be displayed so as to move appropriately in accordance with the rotation.

[0046] On the other hand, diagnostic information including malfunction information tends to be concentrated on the center line of the pneumatic diaphragm, for example, and on the actuator axis, which is coaxial with the valve axis in a typical direct-acting valve. Therefore, by rotating the information processing device 100 around the actuator axis rather than the centroid axis of the valve diagram, the display of diagnostic information including malfunction information is less likely to shift, and the display position of the diagnostic information can be fixed as much as possible. As a result, the information processing device 100 can further improve the ease of understanding of information presented, particularly for malfunction detection and condition diagnosis of the valve 200.

[0047] The rotation unit 143 rotates the obliquely displayed diagram of the valve around the actuator axis, which allows the information processing device 100 to particularly reduce the amount of movement of the diagnostic information compared to when the diagnostic information is rotated around the centroid axis, which requires a greater movement of the display position of the diagnostic information than usual.

[0048] [5. Hardware Configuration] The information processing device 100 according to the embodiment is realized, for example, by a computer 1000 configured as shown in Fig. 8. Fig. 8 is a diagram showing an example of a hardware configuration. The computer 1000 has a configuration in which a CPU 1100, a RAM 1200, a ROM 1300, an auxiliary storage device 1400, a communication I / F (interface) 1500, and an input / output I / F 1600 are connected by a bus 1800.

[0049] The CPU 1100 controls each unit based on a program 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 predetermined communication network.

[0050] The CPU 1100 controls output devices such as a display and a printer, and input / output devices 1700 such as a keyboard and a mouse, via the input / output I / F 1600. For example, the CPU 1100 acquires data from the input / output device 1700 via the input / output I / F 1600 and outputs generated data to the input / output device 1700. The CPU 1100 also executes a program loaded onto the RAM 1200 to implement the functions of the control unit 140.

[0051] [6. Other] Although some embodiments of the present invention have been described in detail with reference to the drawings, these are merely examples, and the present invention can be implemented in other forms that involve various modifications and improvements based on the knowledge of those skilled in the art, or that are appropriately combined, including the forms described in the disclosure of the invention.
