[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 numerical information, which is time-series data regarding the opening of a valve, an opening change unit that changes the opening of a valve diagram showing the valve to an opening corresponding to the numerical information acquired by the acquisition unit, and a display control unit that displays, together with the numerical information, the diagram of the valve whose opening has been changed by the opening change unit to an opening corresponding to the numerical information. [Effects of the Invention]

[0006] The present invention has the effect of improving the ease of understanding of information presented for detecting malfunctions and diagnosing the state of valves in particular. [Brief explanation of the drawings]

[0008] Hereinafter, embodiments of an information processing device, an information processing method, and an information processing program according to the present invention will be described in detail with reference to the accompanying 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, from the valve 200, numerical information that is time-series data relating to the opening of the valve 200. The information processing device 100 then changes the opening of a diagram of the valve showing the valve 200 to an opening corresponding to the acquired numerical information, and displays the diagram of the valve whose opening has been changed to the opening corresponding to the numerical information together with the numerical information.

[0011] For example, when an operator specifies 13:14, which is a predetermined time in a graph in which numerical information for each time is represented as time-series data, the information processing device 100 obtains an opening of 84% for the valve 200 at 13:14. The information processing device 100 then changes the opening of the valve diagram to an opening corresponding to 84% and displays the diagram of the valve changed to the aforementioned opening together with a graph showing the opening of the valve 200 at each time.

[0012] In this way, the information processing device 100 displays a diagram of the valve 200 that shows the valve 200 with its opening changed to correspond to the numerical information, along with the numerical information that is the basis for diagnosing the normality or abnormality of the valve 200. This makes it possible for the information processing device 100 to improve the ease of understanding of information presented, particularly for detecting malfunctions and diagnosing the state 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 numerical information, which is time-series data relating to the opening of the valve 200, as well as a diagram of the valve showing the valve 200 whose opening has been changed to the opening corresponding to the numerical 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 a CPU (Central Processing Unit), an MPU (Micro Processing Unit), or the like executing various programs stored in the storage unit 110 using RAM as a work area. The control unit 140 is also realized by 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, an opening degree change unit 142, a display control unit 143, and an instruction unit 144.

[0019] The acquisition unit 141 acquires numerical information, which is time-series data relating to the opening of the valve 200. An example of the acquisition process by the acquisition unit 141 will be described below with reference to Fig. 4. Fig. 4 is a diagram showing an example of numerical information and a valve diagram. Fig. 4 shows a graph 300 in which the opening of a valve diagram 400 changes depending on the numerical information at a predetermined time.

[0020] 4, the predetermined time, 13:14, is specified in graph 300, in which numerical information at each time is represented as time-series data, by a hairline 301 or the like, which is a line specifying the predetermined time. In this case, acquisition unit 141 acquires 84[%], which is the opening degree of valve 200 at the predetermined time, 13:14, stored in storage unit 110.

[0021] Here, the acquisition unit 141 acquires, as the opening degree of the valve 200, an "Input" of 84 [%], which is the desired opening degree of the valve 200 that has been input, and a "Travel (Tvl.)" of 84 [%], which is the actual opening degree of the valve 200 that corresponds to the "Input".

[0022] Returning to the explanation of Fig. 2, the acquisition unit 141 can acquire the numerical information by various known methods, such as a method of acquiring static numerical information already stored in the storage unit 110, or a method of acquiring numerical information in real time from the positioner 201 via the communication unit 130.

[0023] When acquiring static numerical information already stored in the storage unit 110, the storage unit 110 stores the numerical information received from the positioner 201 of the valve 200 in FIG. 3 via the communication unit 130 in accordance with, for example, an operator's settings. The acquisition unit 141 then acquires the numerical information from the storage unit 110. When acquiring numerical information in real time from the positioner 201 via the communication unit 130, the acquisition unit 141 acquires the numerical information without going through the storage unit 110.

[0024] The opening changing unit 142 changes the opening of the valve diagram showing the valve 200 to an opening corresponding to the numerical information acquired by the acquiring unit 141. For example, the opening changing unit 142 changes the position of the valve stem in the valve diagram corresponding to the valve stem 202 of the valve 200 in Fig. 3, 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 performs processing to change the position of the valve stem for image information of the valve diagram displayed on the display unit 120 of the information processing device 100 as a PC monitor screen or the like, so that the opening corresponds to the numerical information.

[0025] The display control unit 143 displays, together with the numerical information, a diagram of the valve whose opening has been changed by the opening change unit 142 to a value corresponding to the numerical information. An example of the display control process by the display control unit 143 will be described below with reference to Fig. 4. In Fig. 4, the acquisition unit 141 acquires 84[%], which is the opening of the valve 200 at 1:14 pm, and the opening change unit 142 changes the opening of the valve diagram 400 to the opening corresponding to 84[%].

[0026] In this case, the display control unit 143 causes the display unit 120 to display, together with the graph 300, a diagram 400 of a valve whose opening has been changed by the opening change unit 142 to correspond to an opening of 84%. In the example of Fig. 4, the display control unit 143 causes the display unit 120 to display the diagram 400 of a valve whose valve stem 401 has been moved to a position where the opening indicator needle 402 points above the vertical center of the opening indicator scale plate 403 (see area A in Fig. 4).

[0027] Returning to the explanation of Figure 2, the instruction unit 144 instructs the opening change unit 142 to change the opening of the valve diagram to a predetermined opening corresponding to a predetermined process. For example, the predetermined process is at least one of an operator's input regarding a predetermined opening and measurement of the time until a predetermined time has elapsed. The predetermined opening is, for example, an opening defined as a guide for the operator to recognize the opening range, and is, for example, fully closed or fully open.

[0028] An example of instruction processing by the instruction unit 144 will be described below with reference to Fig. 4. As an example, when the instruction unit 144 receives at least one of the following processes (1) and (2), it instructs the opening degree changing unit 142 to change the opening degree of the valve in Fig. 400 to fully closed for a predetermined time. (1) The operator clicks on the "Fully Closed" area 500, which is a UI (User Interface) for displaying the valve diagram 400 displayed on the monitor screen as fully closed. (2) A process in which the instruction unit 144 or another functional unit in the control unit 140 measures time until a predetermined time corresponding to a predetermined cycle of change in the value of the numerical information has elapsed.

[0029] Regarding (2) above, in Fig. 4, the cycle from the most recent full closure to the next full closure is approximately 10 minutes. Therefore, the instructing unit 144 instructs the opening changing unit 142 to change the opening of the valve in the diagram 400 to fully closed, for example, every time it measures approximately 10 minutes, which is the same cycle, or approximately 5 minutes, which is half of this cycle, from the most recent full open to the next full closure.

[0030] As another example, when the instruction unit 144 receives at least one of the processes (2) above and (3) below, it instructs the opening change unit 142 to change the opening of the valve in diagram 400 to fully open for a predetermined period of time. (3) The operator clicks on the "Fully Open" area 600, which is a UI for displaying the valve diagram 400 displayed on the monitor screen in a fully open state.

[0031] 4 to 6, an example of changing the opening of the valve diagram 400 based on an instruction from the instruction unit 144 will be described. Fig. 5 is a diagram showing an example of the valve diagram when the opening is fully closed. Fig. 6 is a diagram showing an example of the valve diagram when the opening is fully open.

[0032] 4 and 5, an example of changing the degree of opening of a valve diagram 400 to fully closed based on an instruction from the instruction unit 144 will be described. Here, it is assumed that the display control unit 143 has caused the graph 300 and the valve diagram 400 shown in Fig. 4 to be displayed on the display unit 120. In this state, when the instruction unit 144 receives a process of clicking on the "fully closed" area 500, it instructs the opening degree changing unit 142 to change the degree of opening of the valve diagram 400 to fully closed.

[0033] Then, the opening change unit 142 moves the valve stem 401 to a lower limit position where the opening indicator needle 402 of the valve diagram 400 points to the lower end of the opening indicator scale plate 403, so as to change from the state of area A in Fig. 4 to the state of area B in Fig. 5, and changes the opening of the valve diagram 400 to fully closed. Then, the display control unit 143 switches the valve diagram 400 shown in Fig. 4 to the valve diagram 400 shown in Fig. 5 in which the position of the valve stem 401 has moved to the lower limit, and displays this for a predetermined period of time.

[0034] 4 and 6, an example of changing the degree of opening of the valve diagram 400 to fully open based on an instruction from the instruction unit 144 will be described. Here, it is assumed that the display control unit 143 has caused the graph 300 and the valve diagram 400 shown in Fig. 4 to be displayed on the display unit 120. In this state, when the instruction unit 144 receives a process of clicking on the "fully open" area 600, it instructs the opening degree changing unit 142 to change the degree of opening of the valve diagram 400 to fully open.

[0035] Then, the opening change unit 142 moves the valve stem 401 to the upper limit position where the opening indicator needle 402 of the valve diagram 400 points to the upper end of the opening indicator scale plate 403, so as to change from the state of area A in Fig. 4 to the state of area C in Fig. 6, and changes the opening of the valve diagram 400 to fully open. Then, the display control unit 133 switches the valve diagram 400 shown in Fig. 4 to the diagram shown in Fig. 6 in which the position of the valve stem 401 has moved to the upper limit position, and displays this for a predetermined period of time.

[0036] 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, for example, by simultaneously executing S102 and S103, and S106 and S107. Also, some of the following processes, such as S104 to S107, may be omitted.

[0037] The acquisition unit 141 of the information processing device 100 acquires numerical information, which is time-series data relating to the opening of the valve 200 (S101). Then, the opening change unit 142 changes the opening of the valve diagram showing the valve 200 to an opening corresponding to the numerical information acquired by the acquisition unit 141 (S102). Next, the display control unit 143 displays the diagram of the valve whose opening has been changed by the opening change unit 142 to the opening corresponding to the numerical information, together with the numerical information (S103).

[0038] Thereafter, when the instruction unit 144 receives a predetermined process (S104; Yes), it instructs the opening changing unit 142 to change the opening of the valve diagram to a predetermined opening corresponding to the predetermined process (S105). Then, the opening changing unit 142 changes the opening of the valve diagram to the predetermined opening corresponding to the predetermined process (S106).

[0039] Next, the display control unit 143 displays, for a predetermined time, an illustration of the valve whose opening has been changed to a predetermined opening by the opening change unit 142 (S107). After S107, or if the instruction unit 144 does not accept a predetermined process (S104; No), the information processing device 100 ends the process.

[0040] [4. Modifications] (Modification of Acquisition Unit 141 and Display Control Unit 143) 4, the acquisition unit 141 acquires numerical information at one time, and the display control unit 143 displays a diagram 400 of a valve whose opening has been changed to a degree corresponding to the numerical information at one time, but the acquisition unit 141 and the display control unit 143 are not limited to this configuration. For example, when the time is changed continuously, the acquisition unit 141 can acquire numerical information at each continuously changed time, and the display control unit 143 can display a diagram 400 of a valve whose opening has been changed to a degree corresponding to the continuously changed numerical information at each time.

[0041] For example, when an operation is performed to move hairline 301, which is a line specifying a predetermined time, in the direction of the time axis of graph 300, acquisition unit 141 acquires numerical information for each specified time in accordance with the movement of hairline 301. Furthermore, display control unit 143 displays, as a moving image, diagram 400 of a valve whose opening degree is continuously changed to correspond to the numerical information for each time.

[0042] An example of the acquisition process by acquisition unit 141 and the display control process by display control unit 143 when the operator performs an operation to move hairline 301 from 13:14 to 13:16 will be described below.

[0043] In this case, the acquisition unit 141 first acquires the opening degree of the valve 200 at 13:14. Next, the acquisition unit 141 acquires "Input" 110[%] and "Travel (Tvl.)" 110[%] as the opening degree of the valve 200 at 13:15. Then, the acquisition unit 141 acquires "Input" 125[%] and "Travel (Tvl.)" 120[%] as the opening degree of the valve 200 at 13:16.

[0044] The display control unit 143 first displays a diagram 400 of the valve whose "travel (Tvl.)" has been changed to an opening corresponding to 84% which is the actual opening of the valve 200 at 1:14 PM. Next, the display control unit 143 displays a diagram 400 of the valve whose "travel (Tvl.)" has been changed to an opening corresponding to 110% which is the actual opening of the valve 200 at 1:15 PM. Then, the display control unit 143 displays a diagram 400 of the valve whose "travel (Tvl.)" has been changed to an opening corresponding to 120% which is the actual opening of the valve 200 at 1:16 PM.

[0045] (Variations of numerical information) 4 to 6, the numerical information is a line graph of past time-series data including "Input," which is time-series data relating to the desired opening of valve 200, and "Travel (Tvl.)," which is time-series data relating to the actual opening of valve 200. However, the numerical information is not limited to this configuration, and any time-series data relating to the opening of valve 200, such as the actual numerical value of the opening of valve 200 at each time in real time, can be used.

[0046] Modified examples of the numerical information will be described below with reference to Figs. 8 and 9. Figs. 8 and 9 are diagrams showing modified examples of the numerical information. In Fig. 8, the display control unit 143 displays only "Travel (Tvl.)" as numerical information on the graph 300. In Fig. 9, the display control unit 143 displays only "Input" as numerical information on the graph 300. In this way, the numerical information may be, for example, only "Travel (Tvl.)" or only "Input".

[0047] 8 and 9, regardless of the above-mentioned differences, the display control unit 143 displays a diagram 400 of the valve whose opening has been changed to correspond to 30% "travel (Tvl.)", which is the actual opening of the valve 200 at 1:19 PM. In other words, the display control unit 143 displays a diagram 400 of the valve whose valve stem 401 has been moved to a position where the opening indicator needle 402 points below the vertical center of the opening indicator dial plate 403 (see area D in FIGS. 8 and 9).

[0048] In this way, the display control unit 143 can display a diagram 400 of the valve whose opening has been changed to correspond to the "travel (Tvl.)", which is the actual opening of the valve 200, rather than the "input", regardless of whether the displayed numerical information is only the "input (Input)".

[0049] (Modification of the valve 200) 3 to 6, 8 and 9, the valve 200 is fully closed when the valve stem 202 is in the lower limit position and fully open when it is in the upper limit position, but this configuration is not limited to this, and for example, the valve 200 may be fully closed when the valve stem 202 is in the upper limit position and fully open when it is in the lower limit position.

[0050] (Variation of valve diagram 400) In Figures 4 to 6, 8 and 9, the diagram 400 of the valve was generated by CAD (Computer-Aided Design), but it is not particularly limited as long as it is a diagram showing the valve 200, such as a diagram in which the change in position of the valve stem 401 according to the opening degree can be recognized.

[0051] For example, the valve diagram 400 may be a realistic diagram such as a design drawing, or may be a simplified schematic diagram that simply represents the components. The valve diagram 400 may have any size, orientation, position on the monitor screen, etc. The timing at which the display control unit 143 displays the valve diagram 400 is not limited to after the opening is changed, and may be, for example, the same time as the opening change unit 142 changes the opening of the valve diagram 400.

[0052] 5. Effects of the embodiment As described above, the information processing device 100 according to 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, which is time-series data relating 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 an opening degree corresponding to the numerical information acquired by the acquisition unit 141. The display control unit 143 displays, together with the numerical information, the diagram of the valve whose opening degree has been changed by the opening degree changing unit 142 to the opening degree corresponding to the numerical information.

[0053] In this way, the information processing device 100 displays a diagram of the valve 200 that shows the valve 200 with its opening changed to correspond to the numerical information, along with the numerical information that is the basis for diagnosing the normality or abnormality of the valve 200. This makes it possible for the information processing device 100 to improve the ease of understanding of information presented, particularly for detecting malfunctions and diagnosing the state of the valve 200.

[0054] Here, stick-slip and hunting are characterized by abnormal movement of the valve stem 202, so if the illustration of the valve is a still image, some operators may easily mistake it for a sticking phenomenon, which can be confusing.

[0055] In response to this, the information processing device 100 employs a moving image display as the display format for the valve diagram, in order to display a diagram of the valve whose opening has been changed to correspond to the numerical information. This allows the information processing device 100 to express an image of abnormal movement of the valve stem 202, particularly stick-slip or hunting, together with the numerical information of the opening of the valve 200, thereby improving the ease of understanding for the operator.

[0056] Furthermore, when a predetermined time is specified in a graph in which the numerical information at each time is expressed as time-series data, the acquisition unit 141 acquires the numerical information at the predetermined time, which allows the information processing device 100 to ultimately display a diagram of the valve whose opening has been changed to correspond to the numerical information at the predetermined time, which is a time desired by an operator or the like.

[0057] Furthermore, when an operation is performed to move a line specifying a predetermined time along the time axis of the graph, the acquisition unit 141 acquires numerical information for each specified time as the line moves. This allows the information processing device 100 to display, as a moving image, a diagram of a valve whose opening degree is continuously changed to correspond to the numerical information for each specified time as the line is moved by an operator or the like, thereby further improving the ease of understanding of the information.

[0058] Furthermore, the numerical information includes time-series data regarding the desired opening of the valve 200 and time-series data regarding the actual opening of the valve 200. As a result, the information processing device 100 can display these time-series data. Therefore, the information processing device 100 can allow an operator or the like to easily diagnose the state of the valve 200 based on the degree to which the time-series data regarding the actual opening of the valve 200 follows the time-series data regarding the desired opening of the valve 200.

[0059] The information processing device 100 also includes an instruction unit 144 that instructs the opening change unit 142 to change the opening of the valve diagram to a predetermined opening corresponding to a predetermined process. Here, the valve 200 may maintain a substantially constant opening over a long period of time. For example, if the position of the valve stem in the valve diagram is changed in accordance with time-series data on the opening, the valve diagram may end up looking like a still image. When the valve diagram looks like a still image, it becomes difficult to understand the operating range of the valve stem corresponding to the opening range, making it difficult for the operator to understand the valve diagram.

[0060] In response to this, the instruction unit 144 instructs the opening change unit 142 to change the opening of the valve diagram to a predetermined opening that is defined as a guide for the operator to recognize the opening range, and therefore the information processing device 100 can improve the ease of understanding of the valve diagram.

[0061] The predetermined process is at least one of an operator's input of a predetermined opening and a measurement of the time until a predetermined time has elapsed. This allows the information processing device 100 to change the opening of the valve diagram to a predetermined opening when the operator wants to recognize the opening range, for example, thereby improving the ease of understanding of the valve diagram.

[0062] Furthermore, the predetermined opening is either fully closed or fully open. This allows the information processing device 100 to change the opening of the valve diagram to either fully closed or fully open when, for example, the operator wants to recognize the opening range, thereby improving the ease of understanding of the valve diagram.

[0063] [6. Hardware Configuration] An information processing device 100 according to the embodiment is realized, for example, by a computer 1000 configured as shown in Fig. 10. Fig. 10 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.

[0064] 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.

[0065] 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.

[0066] [7. 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.
