[0034] Hereinafter, embodiments of the information processing apparatus, information processing method, and information processing program of the present invention will be described in detail with reference to the accompanying drawings. In addition, the information processing apparatus, information processing method, and information processing program of the present invention are not limited by the above embodiments.

[0035] [1. Structure of Information Processing System 10]

[0036] First, an overview of the information processing system 10 including the information processing apparatus 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 apparatus 100 of the information processing system 10 displays information for detecting a defect or diagnosing a state of a valve 200 such as a control valve commonly used in petrochemical facilities or the like.

[0037] The information processing apparatus 100 is, for example, a personal computer (PC) or the like connected to the valve 200 through a communication component. The information processing apparatus 100 acquires numerical information as time-series data related to the opening degree of the valve 200 from the valve 200. Further, the information processing apparatus 100 changes the opening degree of the valve diagram showing the valve 200 to the opening degree corresponding to the acquired numerical information, and displays the numerical information and the valve diagram whose opening degree has changed to the opening degree corresponding to the numerical information together.

[0038] For example, when the operator designates an operation at a specified time, i.e., 13:14, in the curve graph showing the numerical information of each time as time-series data, the information processing apparatus 100 acquires the opening degree 84 [%] of the valve 200 at 13:14. Further, the information processing apparatus 100 changes the opening degree of the valve diagram to the opening degree corresponding to 84 [%], and displays the curve graph showing the opening degree of the valve 200 at each time and the valve diagram whose opening degree has changed to the above opening degree together.

[0039] In this way, the information processing apparatus 100 displays together the numerical information that is the basis for diagnosing the normality and abnormality of the valve 200, and the valve diagram showing the valve 200 whose opening degree has changed to the opening degree corresponding to the numerical information. Thereby, the information processing apparatus 100 can improve the ease of understanding of the information presented particularly for detecting a defect or diagnosing a state of the valve 200.

[0040] [2. Structure of Information Processing Apparatus 100]

[0041] Next, with reference to Figure 2 and Figure 3 the structure of the information processing apparatus 100 will be described. Figure 2 This is a diagram showing an example of the structure of the information processing apparatus of the embodiment. Figure 3This is a diagram showing an example of the structure of a valve according to an embodiment.

[0042] As Figure 2 shown, the information processing apparatus 100 includes a storage unit 110, a display unit 120, a communication unit 130, and a control unit 140. In addition, the structure of the information processing apparatus 100 is not limited to Figure 2 the structure shown. For example, the display unit 120 of the information processing apparatus 100 may also be located externally.

[0043] 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.

[0044] The display unit 120 displays numerical information, which is time-series data related to the opening degree of the valve 200, and a valve diagram of the valve 200 showing the change to the opening degree corresponding to the numerical information. The display unit 120 is implemented by a monitor of a PC or the like.

[0045] 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 transmission and reception of information.

[0046] The control unit 140 controls the information processing apparatus 100, and is implemented by using a central processing unit (CPU), a micro processing unit (MPU), or the like, and executing various programs stored in the storage unit 110 with the RAM as a 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, an opening degree change unit 142, a display control unit 143, and an instruction unit 144.

[0047] The acquisition unit 141 acquires numerical information, which is time-series data related to the opening degree of the valve 200. Hereinafter, an example of the acquisition process performed by the acquisition unit 141 will be described using Figure 4 This is a diagram showing an example of numerical information and a valve diagram. Figure 4 This is a diagram showing that the opening degree of the valve diagram 400 changes according to the numerical information at a specified time in the curve diagram 300. Figure 4 This is a diagram showing that the opening degree of the valve diagram 400 changes according to the numerical information at a specified time in the curve diagram 300.

[0048] In Figure 4In the figure, by specifying a line at a specified time, i.e., a thin line 301, etc., a specified time, i.e., 13:14, is specified in the graph 300 that represents the numerical information at each time as time series data. In this case, the acquisition unit 141 acquires the opening degree of the valve 200 at the specified time, i.e., 13:14, i.e., 84[%], stored in the storage unit 110.

[0049] Here, the acquisition unit 141 acquires the input desired opening of the valve 200 , namely “input” 84[%], and the actual opening of the valve 200 , namely “stroke (Tvl.)” 84[%] corresponding to the “input”, as the opening of the valve 200 .

[0050] Back to Figure 2 The acquisition unit 141 may acquire the numerical information by various known methods, such as acquiring static numerical information stored in the storage unit 110 or acquiring numerical information from the positioner 201 via the communication unit 130 in real time.

[0051] When acquiring static numerical information stored in the storage unit 110, the storage unit 110 stores the static numerical information received from the communication unit 130 according to the setting of the operator, for example. Figure 3 The acquisition unit 141 then acquires the numerical information from the storage unit 110. When acquiring the numerical information from the positioner 201 via the communication unit 130 in real time, the acquisition unit 141 acquires the numerical information without using the storage unit 110.

[0052] The opening degree changing unit 142 changes the opening degree of the valve diagram showing the valve 200 to an opening degree corresponding to the numerical information acquired by the acquisition unit 141. For example, the opening degree changing unit 142 changes the opening degree of the valve diagram showing the valve 200 to an opening degree corresponding to the numerical information acquired by the acquisition unit 141. Figure 3 The position of the valve shaft in the valve diagram corresponding to the valve shaft 202 of the valve 200 is changed, thereby changing the opening of the valve diagram corresponding to the opening of the valve 203 of the valve 200. As an example, the opening changing unit 142 processes the image information of the valve diagram displayed on the display unit 120 of the information processing device 100 in the form of a monitor screen of a PC, etc., so as to change the position of the valve shaft so that it becomes the opening corresponding to the numerical information.

[0053] The display control unit 143 displays the numerical information together with the valve diagram whose opening degree is changed to correspond to the numerical information by the opening degree changing unit 142. Figure 4 An example of display control processing performed by the display control unit 143 is described. Figure 4 In the example, the acquisition unit 141 acquires the opening degree of the valve 200 at 13:14, that is, 84[%], and the opening degree changing unit 142 changes the opening degree of the valve map 400 to an opening degree corresponding to 84[%].

[0054] In this case, the display control unit 143 displays the curve graph 300 and the valve graph 400 with the opening degree changed to the opening degree corresponding to 84 [%] by the opening degree changing unit 142 on the display unit 120. In Figure 4 the example of, in order to make the graph of the valve 200 correspond to the opening degree of 84 [%], the display control unit 143 displays the valve graph 400 in which the valve shaft 401 is moved to a position where the opening degree display needle 402 points to a position above the center in the vertical direction of the opening degree display scale plate 403 (refer to Figure 4 region A).

[0055] Return to Figure 2 the description of. The instruction unit 144 instructs the opening degree changing unit 142 to change the opening degree of the valve graph to a prescribed opening degree corresponding to a prescribed process. For example, the prescribed process is at least one of an input related to the prescribed opening degree performed by an operator and a measurement of the time until a prescribed time has elapsed. The prescribed opening degree is, for example, an opening degree prescribed as a standard for an operator to identify an opening degree range, and as an example, it is fully closed or fully open.

[0056] Hereinafter, an example of the instruction process performed by the instruction unit 144 will be described using Figure 4 . As an example, when the instruction unit 144 accepts at least one of the following (1) and (2) processes, it instructs the opening degree changing unit 142 to change the opening degree of the valve graph 400 to fully closed only for a prescribed time.

[0057] (1) A process in which an operator clicks on the "fully closed" region 500, which is a user interface (UI) for displaying that the valve graph 400 displayed in the monitor screen is fully closed

[0058] (2) A process of measuring the change measurement time of the value of the numerical information by another functional unit such as the instruction unit 144 or the control unit 140 until a prescribed time corresponding to a prescribed period has elapsed

[0059] Regarding the above (2), in Figure 4 , the period from the most recent full closure to the next full closure is about 10 minutes. Therefore, for example, every time the instruction unit 144 measures about 10 minutes, which is the same as the above period, or about 5 minutes, which is half of the above period, from the most recent full opening to the next full closure, it instructs the opening degree changing unit 142 to change the opening degree of the valve graph 400 to fully closed.

[0060] As another example, when the instruction unit 144 receives the processing of at least one of the above (2) and the following (3), it instructs the opening degree changing unit 142 to change the opening degree of the valve diagram 400 to fully open only for a specified time.

[0061] (3) The operator clicks on the "fully open" area 600, and the "fully open" area 600 is a UI for displaying that the valve diagram 400 displayed in the monitor screen is fully open.

[0062] Here, use Figures 4 - 6 , to illustrate an example in which the opening degree of the valve diagram 400 changes based on the instruction of the instruction unit 144. Figure 5 FIG. is an example of a valve diagram when the opening degree is fully closed. Figure 6 FIG. is an example of a valve diagram when the opening degree is fully open.

[0063] First, use Figure 4 and Figure 5 , to illustrate an example in which the opening degree of the valve diagram 400 changes to fully closed based on the instruction of the instruction unit 144. Here, it is assumed that the display control unit 143 is in a state of displaying the curve graph 300 and the valve diagram 400 shown in Figure 4 on the display unit 120. In this state, when the instruction unit 144 receives the processing of clicking on the "fully closed" area 500, it instructs the opening degree changing unit 142 to change the opening degree of the valve diagram 400 to fully closed.

[0064] Then, the opening degree changing unit 142 moves the valve shaft 401 to the lower limit position where the opening degree display needle 402 of the valve diagram 400 points to the lower end of the opening degree display scale plate 403, so as to change from the state of Figure 4 in area A to the state of Figure 5 in area B, thereby changing the opening degree of the valve diagram 400 to fully closed. Then, the display control unit 143 switches the valve diagram 400 shown in Figure 4 to the valve diagram 400 in which the position of the valve shaft 401 shown in Figure 5 has moved to the lower limit position and displays it for only a specified time.

[0065] Next, use Figure 4 and Figure 6 , to illustrate an example in which the opening degree of the valve diagram 400 changes to fully open based on the instruction of the instruction unit 144. Here, it is assumed that the display control unit 143 is in a state of displaying the curve graph 300 and the valve diagram 400 shown in Figure 4 on the display unit 120. In this state, when the instruction unit 144 receives the processing of clicking on the "fully open" area 600, it instructs the opening degree changing unit 142 to change the opening degree of the valve diagram 400 to fully open.

[0066] Then, the opening degree changing unit 142 moves the valve shaft 401 to the upper limit position where the opening degree display needle 402 of the valve diagram 400 points to the upper end of the opening degree display scale plate 403, so as to change from Figure 4 the state of area A to Figure 6 the state of area C, thereby changing the opening degree of the valve diagram 400 to fully open. Then, the display control unit 143 switches the Figure 4 shown valve diagram 400 to Figure 6 the diagram where the position of the valve shaft 401 has moved to the upper limit position as shown and displays it for only a specified time.

[0067] [3. Processing Flow of Information Processing Device 100]

[0068] Next, an example of the processing flow of the information processing device 100 based on the embodiment will be described using Figure 7 . Figure 7 FIG. is a flowchart showing an example of the processing flow of the information processing device according to the embodiment. In addition, for example, the following respective processes may also execute different sequences such as S102 and S103, and S106 and S107 simultaneously. Also, in the following respective processes, for example, processes such as S104 to S107 may be omitted.

[0069] The acquisition unit 141 of the information processing device 100 acquires numerical information as time series data related to the opening degree of the valve 200 (S101). Then, the opening degree changing unit 142 changes the opening degree of the valve diagram showing the valve 200 to the opening degree corresponding to the numerical information acquired by the acquisition unit 141 (S102). Next, the display control unit 143 simultaneously displays the numerical information and the valve diagram whose opening degree has been changed to the opening degree corresponding to the numerical information by the opening degree changing unit 142 (S103).

[0070] After that, when the instruction unit 144 accepts a specified process (S104; Yes), it instructs the opening degree changing unit 142 to change the opening degree of the valve diagram to a specified opening degree corresponding to the specified process (S105). Then, the opening degree changing unit 142 changes the opening degree of the valve diagram to the specified opening degree corresponding to the specified process (S106).

[0071] Next, the display control unit 143 displays the valve diagram whose opening degree has been changed to the specified opening degree by the opening degree changing unit 142 for a specified time (S107). After S107, or when the instruction unit 144 does not accept the specified process (S104; No), the information processing device 100 ends the process.

[0072] [4. Modification Example]

[0073] (Modification Examples of Acquisition Unit 141 and Display Control Unit 143)

[0074] In Figure 4 , the acquisition unit 141 acquires numerical information at a certain moment, and the display control unit 143 displays the valve diagram 400 whose opening degree changes to correspond to the numerical information at a certain moment. However, the acquisition unit 141 and the display control unit 143 are not limited to such a structure. For example, when the acquisition unit 141 continuously changes the moment, it can acquire the numerical information at each moment after the continuous change, and the display control unit 143 can display the valve diagram 400 whose opening degree changes to correspond to the numerical information at each moment after the continuous change.

[0075] For example, when the acquisition unit 141 performs an operation of moving the thin line 301 indicating a specified moment in the time axis direction of the curve graph 300, it acquires the numerical information at each moment specified along with the movement of the thin line 301. In addition, the display control unit 143 displays the valve diagram 400 whose opening degree continuously changes to correspond to the numerical information at each moment as an animation.

[0076] Hereinafter, an example of the acquisition process performed by the acquisition unit 141 and the display control process performed by the display control unit 143 when an operator moves the thin line 301 from 13:14 to 13:16 will be described.

[0077] In this case, the acquisition unit 141 first acquires the opening degree of the valve 200 at 13:14. Subsequently, the acquisition unit 141 acquires "Input" 110 [%] and "Tvl." 110 [%] as the opening degree of the valve 200 at 13:15. Then, the acquisition unit 141 acquires "Input" 125 [%] and "Tvl." 120 [%] as the opening degree of the valve 200 at 13:16.

[0078] The display control unit 143 first displays the valve diagram 400 whose opening degree changes to correspond to the actual opening degree of the valve 200 at 13:14, that is, "Tvl." 84 [%]. Subsequently, the display control unit 143 displays the valve diagram 400 whose opening degree changes to correspond to the actual opening degree of the valve 200 at 13:15, that is, "Tvl." 110 [%]. Then, the display control unit 143 displays the valve diagram 400 whose opening degree changes to correspond to the actual opening degree of the valve 200 at 13:16, that is, "Tvl." 120 [%].

[0079] (Variant example of numerical information)

[0080] In Figures 4 - 6In [description], the numerical information is a line graph of past time-series data, and the past time-series data includes time-series data related to the desired opening degree of valve 200, namely "Input", and time-series data related to the actual opening degree of valve 200, namely "Tvl.". However, the numerical information is not limited to this structure, and it can adopt the numerical value itself of the opening degree of valve 200 at each moment in real time, etc., and time-series data related to the opening degree of any valve 200.

[0081] Hereinafter, [description] will be used Figure 8 and Figure 9 to illustrate a modified example of the numerical information. Figure 8 and Figure 9 are diagrams showing modified examples of the numerical information. In Figure 8 , the display control unit 143 only displays "Tvl." as the numerical information in the line graph 300. Additionally, in Figure 9 , the display control unit 143 only displays "Input" as the numerical information in the line graph 300. Thus, the numerical information can be, for example, only "Tvl." or only "Input".

[0082] Furthermore, in Figure 8 and Figure 9 , regardless of the above differences, the display control unit 143 always displays the valve diagram 400 that changes to the opening degree corresponding to the actual opening degree of valve 200 at 13:19, namely "Tvl.", which is 30 [%]. That is, the display control unit 143 displays the valve diagram 400 in which the valve shaft 401 is moved to a position where the opening degree display needle 402 points to a position lower than the center of the vertical direction of the opening degree display scale plate 403 (refer to Figure 8 and Figure 9 for area D).

[0083] Thus, regardless of whether the displayed numerical information is only "Input", the display control unit 143 can display the valve diagram 400 that changes to the opening degree corresponding to the actual opening degree of valve 200, namely "Tvl.", rather than "Input".

[0084] (Modified example of valve 200)

[0085] In addition, in Figures 3 - 6 , Figure 8 and Figure 9 , valve 200 is fully closed when the position of the valve shaft 202 is at the lower limit position and fully open when the position of the valve shaft 202 is at the upper limit position. However, it is not limited to this structure. For example, it can also be fully closed when the position of the valve shaft 202 is at the upper limit position and fully open when the position of the valve shaft 202 is at the lower limit position.

[0086] (Modified Example of Valve Diagram 400)

[0087] In Figures 4 - 6 、 Figure 8 and Figure 9 the valve diagram 400 is generated by computer-aided design (CAD), but any diagram showing the valve 200, such as a diagram that can identify the positional change of the valve shaft 401 according to the opening degree, is not particularly limited.

[0088] For example, the valve diagram 400 can be a real diagram like a design diagram or a simple diagram that concisely represents the components. In addition, in the valve diagram 400, any size, direction, position within the monitor screen, etc. can be adopted. In addition, the timing of displaying the valve diagram 400 by the display control unit 143 is not limited to after the opening degree changes. For example, it can also be simultaneous with the timing of changing the opening degree of the valve diagram 400 by the opening degree changing unit 142.

[0089] 〔5. Effects of Embodiment〕

[0090] As described above, the information processing apparatus 100 of the embodiment includes an acquisition unit 141, an opening degree changing unit 142, and a display control unit 143. The acquisition unit 141 acquires numerical information as time series data related to the opening degree of the valve 200. The opening degree changing unit 142 changes the opening degree of the valve diagram showing the valve 200 to the opening degree corresponding to the numerical information acquired by the acquisition unit 141. The display control unit 143 displays the numerical information and the valve diagram whose opening degree has been changed to the opening degree corresponding to the numerical information by the opening degree changing unit 142 together.

[0091] In this way, the information processing apparatus 100 displays together the numerical information that serves as the basis for diagnosing the normality and abnormality of the valve 200, and the valve diagram showing the valve 200 whose opening degree has been changed to the opening degree corresponding to the numerical information. Thereby, the information processing apparatus 100 can improve the ease of understanding of the information presented especially for detecting the defective condition or diagnosing the state of the valve 200.

[0092] Here, the characteristics of stick-slip or hunting vibration are that the valve shaft 202 makes abnormal movements. Therefore, if the valve diagram is a still image, the operator is likely to misunderstand it as a sticking phenomenon, which is the main cause of confusion.

[0093] In contrast, the information processing apparatus 100 adopts animation display as the display form of the valve diagram in order to display the valve diagram whose opening degree has been changed to the opening degree corresponding to the numerical information. Thereby, the information processing apparatus 100 can display together the image of the abnormal movement of the valve shaft 202, such as stick-slip or hunting vibration in particular, and the numerical information of the opening degree of the valve 200, so the ease of understanding for the operator can be improved.

[0094] In addition, when the acquisition unit 141 designates a specified time in the line graph representing the numerical information at each time as time-series data, the acquisition unit 141 acquires the numerical information at the specified time. As a result, the information processing apparatus 100 can display a valve diagram whose opening changes to correspond to the numerical information at the specified time, which is a desired time for an operator or the like.

[0095] In addition, when an operation of moving the line designating the specified time in the time-axis direction of the line graph is performed, the acquisition unit 141 acquires the numerical information at each time designated along with the movement of the line. As a result, the information processing apparatus 100 can display, in the form of an animation, a valve diagram in which the opening continuously changes to correspond to the numerical information at each time designated along with the movement of the line caused by an operation by an operator or the like, and thus the ease of understanding the information can be further improved.

[0096] In addition, the numerical information includes time-series data related to the desired opening of the valve 200 and time-series data related to the actual opening of the valve 200. As a result, the information processing apparatus 100 can display these time-series data. Therefore, the information processing apparatus 100 can enable an operator or the like to easily diagnose the state of the valve 200 based on the degree of follow-up of the time-series data related to the actual opening of the valve 200 with respect to the time-series data related to the desired opening of the valve 200.

[0097] In addition, the information processing apparatus 100 further includes an instruction unit 144 that instructs the opening change unit 142 so that the opening of the valve diagram changes to a specified opening corresponding to a specified process. Here, the valve 200 may be at a substantially constant opening for a long time. For example, when changing the position of the valve axis of the valve diagram according to the time-series data of the opening, there is a possibility that the valve diagram becomes a still image. And when it becomes a still image, in particular, the operating range of the valve axis corresponding to the opening range becomes difficult to understand, and thus it is difficult for the operator to understand the valve diagram.

[0098] In contrast, the instruction unit 144 instructs the opening change unit 142, for example, so that the opening of the valve diagram changes to a specified opening defined as a standard for an operator to recognize the opening range. Therefore, the information processing apparatus 100 can improve the ease of understanding the valve diagram.

[0099] In addition, the specified process is at least one of an input related to a specified opening performed by an operator and a measurement of the time until a specified time has elapsed. As a result, the information processing apparatus 100 can, for example, change the opening of the valve diagram to a specified opening when an operator desires to recognize the opening range, and thus can improve the ease of understanding the valve diagram.

[0100] In addition, the specified opening degree is fully closed or fully open. Thus, when an operator desires to recognize the opening degree range, for example, the information processing apparatus 100 can change the opening degree of the valve diagram to fully closed or fully open, thereby improving the ease of understanding of the valve diagram.
