[0012] Hereinafter, an embodiment of a display control method, a display control device, and a display control program according to the present disclosure will be described with reference to FIGS.

[0013] [1. Display control method] 1, the display control method of this embodiment is used as a method in which a display control device 1 controls a device display unit (display unit) 10 and terminal display units (display units) 51A and 51B of terminals 50A and 50B (described later). The display control device 1 is connected to a plant 20 that includes multiple devices (not shown). For example, the plant 20 includes an abnormality sensor (not shown) that detects whether or not there is an abnormality in each device. Each abnormality sensor transmits the detection result to the display control device 1. The display control device 1 may be capable of controlling a plurality of devices.

[0014] For example, the device display unit 10 is configured with a relatively large liquid crystal display, a TFT (Thin Film Transistor) display, etc. Details of the display control device 1 will be described later.

[0015] The display control device 1 is connected to an input unit 11 and a storage unit 12. The input unit 11 is a device through which a device user (user, user) of the display control device 1 (display control method) gives instructions to the display control device 1. For example, the input unit 11 is composed of a keyboard, a mouse, etc. Each device user is assigned user identification information. The device user operates the input unit 11 to input user identification information, logs in to the display control device 1, and then uses the display control device 1.

[0016] Equipment users have two technical levels (authority): operator and engineer (predetermined authority). For example, an equipment user with an operator technical level only operates multiple pieces of equipment in the plant 20. On the other hand, an equipment user with an engineer technical level not only operates multiple pieces of equipment but also repairs multiple pieces of equipment. Depending on the technical level, the documents that the equipment user can view vary from the manuals and specifications corresponding to the equipment. The user identification information is associated with a skill level. As described above, the device user logs in to the display control device 1 before using the display control device 1, and therefore the display control device 1 recognizes the skill level of the device user. The storage unit 12 is configured with a memory, etc. Various types of information stored in the storage unit 12 will be described later.

[0017] The display control device 1 communicates with a first terminal (terminal) 50A and a second terminal (terminal) 50B by known wireless communication, wired communication, a combination thereof, etc. For example, the first terminal 50A and the second terminal 50B are tablet-type mobile terminals (computers). In this example, the first terminal 50A is a terminal (on-site terminal) used near the plant 20. The second terminal 50B is a terminal (remote monitoring terminal) used at a location away from the plant 20.

[0018] The first terminal 50A and the second terminal 50B may be provided with a terminal display unit (display unit) 51A and a terminal display unit (display unit) 51B that display a system diagram 15 described later. For example, the terminal display units 51A and 51B are configured with a relatively small liquid crystal display, a TFT display, or the like. For example, the first terminal 50A and the second terminal 50B may be able to detect the positions where the first terminal 50A and the second terminal 50B are placed using a GPS (Global Positioning System) function. The number of terminals connected to the display control device 1 may be one, or may be three or more.

[0019] 2, the device display unit 10 displays a system diagram (operation monitoring screen) 15 and a related information display unit 35. The system diagram here refers to a diagram showing the connection relationships between multiple devices in the facility. In this example, a system diagram 15 is displayed in the lower portion of the device display section 10, and a related information display section 35 is displayed in the upper portion of the device display section 10.

[0020] In the present embodiment, as an example of a system diagram, a main part of a system diagram 15 of equipment of a plant 20 is shown. For example, a first icon 21A, a second icon 21B, and a third icon 21C are displayed on the system diagram 15. The first icon 21A indicates a first device, which is a pump, of the plant 20. The second icon 21B indicates a second device, which is a pump, of the plant 20. The third icon 21C indicates a third device, which is a heat exchanger, of the plant 20. The first device and the second device are the same type of device, that is, a pump. The first icon 21A is provided on the first pipe of the third device indicated by the third icon 21C. The second icon 21B is provided on the second pipe of the third device indicated by the third icon 21C.

[0021] The number of devices included in the plant 20 is not limited, and may be one, two, or four or more. In this case, the number of icons displayed on the system diagram corresponds to the number of devices included in the plant 20.

[0022] For example, when the device user selects the first icon 21A on the system diagram 15 by using the input device, the first faceplate image 26A corresponding to the first device shown in Fig. 3 is displayed on the device display unit 10. For example, the first faceplate image 26A is displayed at position P1 on the system diagram 15 shown in Fig. 2. For example, the first faceplate image 26A displays the state quantity of the first device, the device operation mode of the first device, and the like.

[0023] As shown in FIG. 3, a manual icon 27, a specification sheet icon 28, and the like are displayed in the upper portion of the first faceplate image 26A. For example, when a device user with a technical level of operator or engineer selects the manual icon 27 on the first faceplate image 26A by using the input device, the first manual is displayed on the device display unit 10. For example, as shown in FIG. 4, the first manual 55A contains instructions for handling the first device, which is a pump, such as (1) preparation before use, (2) handling instructions, etc.

[0024] When a device user with a technical level of engineer selects the specification icon 28 on the first faceplate image 26A by using the input device, the first specification is displayed on the device display unit 10. For example, as shown in FIG. 5, the first specification 56A describes specifications of the first device, such as (1) pump head, (2) rated voltage, etc. It should be noted that the items described in the first manual 55A and the items described in the first specification 56A are not limited to these.

[0025] When a device user whose technical level is operator selects the specification icon 28 on the first faceplate image 26A by using the input device, the first specification 56A is not displayed on the device display unit 10. In addition, if the device user is an operator, the specification icon 28 does not need to be displayed on the first faceplate image 26A, and even if the specification icon 28 is displayed on the first faceplate image 26A, the specification icon 28 may not be selectable (pressed) using the input device.

[0026] When the device user selects the second icon 21B on the system diagram 15 using an input device, a second faceplate image 26B (see Figure 3) corresponding to the second device, which is similar to the first faceplate image 26A, is displayed on the device display unit 10.

[0027] A manual icon 27, a specification sheet icon 28, and the like are displayed in the upper portion of the second faceplate image 26B. When an equipment user with a technical level of operator and engineer selects the manual icon 27 on the second faceplate image 26B using an input device, a second manual 55B (see Figure 4) corresponding to the second equipment and similar to the first manual 55A is displayed on the equipment display unit 10. When a device user with an engineer technical level selects the specification icon 28 on the second faceplate image 26B using an input device, a second specification 56B (see Figure 5) corresponding to the second device and similar to the first specification 56A is displayed on the device display unit 10.

[0028] When a device user whose technical level is operator selects the specification icon 28 on the second faceplate image 26B by using the input device, the second specification 56B is not displayed on the device display unit 10. In addition, if the device user is an operator, the specification icon 28 does not need to be displayed on the second faceplate image 26B, and even if the specification icon 28 is displayed on the second faceplate image 26B, the specification icon 28 may not be selectable using the input device.

[0029] Next, FIG. 2 will be described. The related information display section 35 includes an alarm information display section 36, a manual icon 37, and a user information display section 38. The alarm information display unit 36 ​​displays the device identification information (to be described later) of the device having an abnormality and the degree of the abnormality (minor malfunction, etc.) based on the detection results transmitted from each abnormality sensor. For example, when a device user with a technical level of operator or engineer selects the manual icon 37 by the input device, the device display unit 10 displays the manual corresponding to the broken device. The user information display section 38 displays the user identification information and skill level of the device user who is logged in to the display control device 1.

[0030] Here, various types of information stored in the storage unit 12 will be described with reference to FIG. The memory unit 12 stores first device identification information that identifies the first device, first icon identification information that identifies the first icon 21A, first faceplate identification information that identifies the first faceplate corresponding to the first icon 21A, and first manual identification information that identifies the first manual 55A. In addition, the memory unit 12 stores second device identification information that identifies the second device, second icon identification information that identifies the second icon 21B, second faceplate identification information that identifies the second faceplate corresponding to the second icon 21B, and second manual identification information that identifies the second manual 55B. In addition, terminal information and operation mode information, which will be described later, are also stored in the storage unit 12 in association with these pieces of information.

[0031] The storage unit 12 also stores first terminal information (terminal information) corresponding to the first terminal 50A and second terminal information (terminal information) corresponding to the second terminal 50B. In this example, the first terminal information indicates that the first terminal 50A is a nearby use terminal (indicates a predetermined terminal) that is used near the plant 20. On the other hand, the second terminal information indicates that the second terminal 50B is a remote use terminal (does not indicate a predetermined terminal) that is used at a location away from the plant 20.

[0032] The manuals 55A and 55B and the specifications 56A and 56B may be stored in the storage unit 12. A distance threshold may also be stored in the storage unit 12. The distance threshold is a threshold for determining whether the first terminal 50A and the second terminal 50B are terminals used near the plant 20 or terminals used at a location far from the plant 20.

[0033] The storage unit 12 may store inspection records and replacement records (maintenance records) for the first device, the second device, and the like. The inspection record of the first device (first inspection record) is a record of the contents of inspections that are performed on the components that make up the first device on a daily basis (for example, about once a week) until the end of the first device's service life. For example, if the first device is a pump, the inspection record will record a set of the vibration value of the output shaft of the first device and the date of measurement. The replacement record of the first device (first replacement record) is a record of replacing the entire first device with a new first device. For example, if the first device is a pump, the service life of the first device is 5 years. For example, the replacement record records the model number of the first device and the date of replacement as a pair. The inspection record (second inspection record) of the second device is the same as the inspection record of the first device. The replacement record (second replacement record) of the second device is the same as the replacement record of the first device.

[0034] For example, the first device identification information and the second device identification information are "Pump 1" and "Pump 2." The first icon identification information and the second icon identification information are "IC1" and "IC2." The first faceplate identification information and the second faceplate identification information are "FP1" and "FP2." The first manual identification information and the second manual identification information are "MN1" and "MN2."

[0035] The storage unit 12 also stores mode information indicating the operation mode (mode) of the plant 20. The operation modes include a "trial operation mode (predetermined mode)" and an "operational operation mode." When the operation mode indicates the trial operation mode, the plant 20 does not perform its normal operation but performs a trial operation for inspection, etc. When the operation mode indicates the production operation mode, the plant 20 performs its normal operation.

[0036] Furthermore, manual priority mode information, which is "manual priority mode" or "normal manual mode," may be stored in the storage unit 12. For example, if the manual priority mode information is the manual priority mode, when the first icon 21A or the second icon 21B is selected on the system diagram 15, the corresponding manuals 55A and 55B are displayed on the device display unit 10 without displaying the corresponding faceplate images 26A and 26B. On the other hand, if the manual priority mode information is the manual normal mode, when the first icon 21A or the second icon 21B is selected on the system diagram 15, the corresponding faceplate images 26A, 26B are displayed, and then the corresponding manuals 55A, 55B are displayed on the device display unit 10.

[0037] Next, the display control method of this embodiment will be described. Fig. 7 is a flowchart showing the display control method S1 of this embodiment. The display control method S1 includes an identification information storage control step S10, a terminal information storage control step S11, a mode information storage control step S12, an icon display control step S13, an abnormality determination step S14, a faceplate display control step S15, a manual display control step S16, and a specification display control step S17. The following description will be given assuming that the technical level of the device user who logs in to the display control device 1 is an operator. In other words, the technical level of the device user is not an engineer. It is also assumed that a terminal user 1 (user) uses a first terminal 50A near the plant 20, and a terminal user 2 (user) uses a second terminal 50B at a location away from the plant 20.

[0038] In the following steps, the system diagram 15 and the like displayed on the device display unit 10 may be displayed on the terminal display units 51A and 51B of the terminals 50A and 50B. However, the second specification sheet 56B is not displayed on the second terminal 50B corresponding to the second terminal information indicating the remotely used terminal.

[0039] First, in an identification information storage control step S10, one of first device identification information that identifies the first device, first icon identification information that identifies the first icon 21A, and first faceplate identification information that identifies the first faceplate corresponding to the first icon 21A is associated with first manual identification information that identifies the first manual 55A and stored in the memory unit 12. Furthermore, any one of second device identification information that identifies the second device, second icon identification information that identifies the second icon 21B, and second faceplate identification information that identifies the second faceplate corresponding to the second icon 21B is associated with second manual identification information that identifies the second manual 55B and stored in the memory unit 12. When the identification information storage control step S10 is completed, the process proceeds to the terminal information storage control step S11.

[0040] Next, in a terminal information storage control step S11, the storage unit 12 stores terminal information corresponding to the first terminal 50A and the second terminal 50B. Specifically, the storage unit 12 stores first terminal information corresponding to the first terminal 50A and indicating a nearby used terminal, and second terminal information corresponding to the second terminal 50B and indicating a remotely used terminal. That is, for first terminal 50A, the first terminal information stored in storage unit 12 indicates a nearby used terminal (indicates a predetermined terminal). For second terminal 50B, the second terminal information stored in storage unit 12 indicates a remotely used terminal (does not indicate a predetermined terminal). When the terminal information storage control step S11 is completed, the process proceeds to the mode information storage control step S12.

[0041] Next, in a mode information storage control step S12, the operation mode information is stored in the storage unit 12. In this example, "test operation mode" is stored as the operation mode information. When the mode information storage control step S12 is completed, the process proceeds to the icon display control step S13. The order in which the identification information storage control step S10, the terminal information storage control step S11, and the mode information storage control step S12 are performed is not limited to this.

[0042] Next, in an icon display control step S13, the device display unit 10 is controlled so that the first icon 21A and the second icon 21B are displayed on the system diagram 15. When the icon display control step S13 is completed, the process proceeds to the abnormality determination step S14.

[0043] Next, in an abnormality determination step S14, it is determined whether an abnormality occurs in any one of the first device, the second device, and the third device. In this example, it is assumed that an abnormality is detected by the abnormality sensor in the first device, which is, for example, a pump. When the abnormality determination step S14 is completed, the process proceeds to the faceplate display control step S15.

[0044] Next, in a faceplate display control step S15, when the device user selects on the system diagram 15 the first icon 21A displayed in the icon display control step S13, a first faceplate image 26A corresponding to the first device is displayed on the device display unit 10. On the other hand, when the device user selects on the system diagram 15 the second icon 21B displayed in the icon display control step S13, a second faceplate image 26B corresponding to the second device is displayed on the device display unit 10. Instead of displaying the first faceplate image 26A on the device display unit 10, an icon of the first faceplate image 26A may be displayed on the device display unit 10. The second faceplate image 26B is similar to the first faceplate image 26A. When the faceplate display control step S15 is completed, the process proceeds to the manual display control step S16.

[0045] Next, in manual display control step S16, when the device user selects the first faceplate image 26A (icon of the first faceplate image 26A) displayed in faceplate display control step S15, a first manual 55A corresponding to the first device is displayed on the device display unit 10. On the other hand, when the device user selects the second faceplate image 26B (icon of the second faceplate image 26B) displayed in faceplate display control step S15, a second manual 55B corresponding to the second device is displayed on the device display unit 10.

[0046] In this example, since an abnormality is determined in the abnormality determination step S14 for the first device, the first manual 55A is displayed on the device display unit 10. In addition, when an abnormality in the first device is not determined in the abnormality determination step S14, when the device user selects the first icon 21A displayed in the icon display control step S13 on the system diagram 15, the first faceplate image 26A corresponding to the first device may be displayed on the device display unit 10, and the first manual 55A may be displayed on the device display unit 10 after the device user operates the manual icon 27 on the first faceplate image 26A.

[0047] When an abnormality in the second device is determined in the abnormality determination step S14, the second manual 55B is displayed on the device display unit 10. When an abnormality in the second device is not determined in the abnormality determination step S14, when the device user selects the second icon 21B displayed in the icon display control step S13 on the system diagram 15, the second faceplate image 26B corresponding to the second device is displayed on the device display unit 10, and the second manual 55B is displayed on the device display unit 10 when the device user operates the manual icon 27 of the second faceplate image 26B. The first manual 55A displayed in the manual display control step S16 is the same as the second manual 55B displayed in the manual display control step S16.

[0048] In addition, when a terminal user 2 using a second terminal 50B for remote monitoring selects the first icon 21A displayed in the icon display control step S13 on the system diagram 15, the first specification 56A is not displayed on the terminal display unit 51B of the second terminal 50B, but the first manual 55A is displayed on the terminal display unit 51B. On the other hand, when the terminal user 2 selects the second icon 21B displayed in the icon display control step S13 on the system diagram 15, the second specification 56B is not displayed on the terminal display unit 51B of the second terminal 50B, but the second manual 55B is displayed on the terminal display unit 51B. When the manual display control step S16 is completed, the process proceeds to the specification display control step S17.

[0049] If the terminal information stored in the memory unit 12 indicates a nearby used terminal (indicates a predetermined terminal), the first specification 56A (second specification 56B) may be displayed on the device display unit 10. If the terminal information stored in the memory unit 12 does not indicate a nearby used terminal, the first manual 55A (second manual 55B) may be displayed on the device display unit 10. The predetermined terminal may also be a remotely used terminal (a terminal used at a location away from the plant 20). The predetermined terminal may also be a terminal installed within the plant 20 and used near the plant 20.

[0050] Next, in specification display control step S17, when the device user selects the first icon 21A displayed in icon display control step S13 on the system diagram 15, a first specification 56A corresponding to the first device is displayed on the device display unit 10. At this time, a first manual 55A may also be displayed on the device display unit 10. On the other hand, when the device user selects the second icon 21B displayed in the icon display control step S13 on the system diagram 15, the second specification 56B corresponding to the second device is displayed on the device display unit 10. At this time, the second manual 55B may also be displayed on the device display unit 10.

[0051] When the device user selects the first icon 21A displayed in the icon display control step S13 on the system diagram 15, the first specification 56A corresponding to the first device is displayed on the device display unit 10. Note that when the terminal user 1 using the first terminal 50A for on-site use selects the first icon 21A displayed in the icon display control step S13 on the system diagram 15, the first specification 56A corresponding to the first device may be displayed on the terminal display unit 51A of the first terminal 50A. When the device user selects the second icon 21B displayed in the icon display control step S13 on the system diagram 15, the second specification 56B corresponding to the second device is displayed on the device display unit 10. Note that when the terminal user 1 selects the second icon 21B displayed in the icon display control step S13 on the system diagram 15, the second specification 56B corresponding to the second device may be displayed on the terminal display unit 51A of the first terminal 50A. When the specification display control step S17 is completed, the process proceeds to step S20.

[0052] Next, in step S20, it is determined whether or not to end the display control method S1. If the device user determines YES in step S20, the display control method S1 ends. On the other hand, if the device user determines NO, the process proceeds to the identification information storage control step S10, and the steps from the identification information storage control step S10 to the specification display control step S17 are repeated. For example, when the test run of the plant 20 is completed, the equipment user determines YES in step S20.

[0053] When the "trial run mode" is stored in the memory unit 12 as the operation mode information, an operator takes a recording sheet and actually inspects the pumps and the like of the plant 20. For example, the operator actually operates the pump and writes down the pump current value and the pump discharge flow rate at that time on the recording sheet. Then, in addition to the first specification 56A or the second specification 56B, an image of the recording sheet during the trial run may be photographed with a nearby terminal or the like and displayed on the device display unit 10.

[0054] Here, a difference from the display control method S1 will be described for a case where the "operational operation mode" is stored as the operation mode information in the storage unit 12. In this case, the operation mode information stored in the storage unit 12 does not indicate the test run mode. In manual display control step S16, when the device user selects on the system diagram 15 the first icon 21A displayed in icon display control step S13, the first specification 56A is not displayed on the device display unit 10, and the first manual 55A is displayed on the device display unit 10. On the other hand, when the device user selects on the system diagram 15 the second icon 21B displayed in icon display control step S13, the second specification 56B is not displayed on the device display unit 10, and the second manual 55B is displayed on the device display unit 10.
