DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, a plant interlocking system according to an embodiment of the present disclosure will be described with reference to the drawings. The plant interlocking system according to the present embodiment is used, for example, for controlling and monitoring a plant. In the present embodiment, the plant is, for example, a factory facility or a production facility such as a stoker furnace, a melting furnace, an on-site cogeneration facility, or a biomass-related facility. The plant interlocking system includes a plurality of control terminals used to control devices such as regulator valves, pumps, valves, etc., that are included in the above-mentioned plants. The plurality of control terminals are provided, for example, in each of the first area and the second area. In this embodiment, the first area is an area separated from the plant to be controlled or monitored. The second area is an area including the site of the plant to be controlled or monitored. The first area and the second area may be located in different regions or different countries, for example. The first area may be located within the same site as the plant, and the second area may be located on a site different from the site where the plant is located. Without being limited to this, the first area and the second area may each be located in an arbitrary location. For example, both the first area and the second area may be located within the same site as the plant. In this embodiment, a user of the plant may remotely control or monitor the plant in a first region using a control terminal, and may also control or monitor the plant at the site of the plant included in a second region using a control terminal.

[0010] (Outline of the plant interlocking system) FIG. 1 is a schematic block diagram showing a system configuration of a plant interlocking system 1 according to an embodiment. 1, the plant interlocking system 1 includes a first control terminal 10 and a second control terminal 20. The first control terminal 10 is one of a plurality of control terminals included in the plant interlocking system 1. The second control terminal 20 is one of a plurality of control terminals included in the plant interlocking system 1, and is a terminal different from the first control terminal 10. In this embodiment, the first control terminal 10 and the second control terminal 20 have the same configuration. In this embodiment, when there is no need to distinguish between the first control terminal 10 and the second control terminal 20, they may be referred to as control terminals.

[0011] 1, the first control terminal 10 is provided in, for example, a first area A1. The second control terminal 20 is provided in, for example, a second area A2. The second control terminal 20 may be provided inside a building of a plant P provided in the second area A2. The first control terminal 10 and the second control terminal 20 are communicatively connected via a network 70. The network 70 may be a network using wireless communication or a network using wired communication. The network 70 may be configured using, for example, the Internet or a local area network (LAN). The network 70 may be configured by combining a plurality of networks. For example, a Virtual Private Network (VPN) may be used for the network 70. This preferably ensures the security of the network 70. Any network may be used for the network 70 as long as security is ensured.

[0012] FIG. 2 is a schematic block diagram showing a specific example of a functional configuration of the first control terminal 10 and the second control terminal 20 according to the embodiment. Below, a functional configuration of the first control terminal 10 will be described. A functional configuration of the second control terminal 20 will not be described as it is the same as that of the first control terminal 10. In the following description of the first control terminal 10, it may be described that the first control terminal 10 controls the second control terminal 20 in a linked manner, but the second control terminal 20 may control the first control terminal 10 in a linked manner.

[0013] The first control terminal 10 is configured using an information device such as a smartphone, a tablet, a personal computer, a dedicated device, etc. The first control terminal 10 includes a communication unit 11, an input unit 12, a display unit 13, a storage unit 14, and a control unit 15.

[0014] The communication unit 11 is a communication device. The communication unit 11 may be configured as, for example, a network interface. The communication unit 11 performs data communication with other devices via the network 70 in response to the control of the control unit 15. The communication unit 11 may be a device that performs wireless communication or a device that performs wired communication.

[0015] The input unit 12 is configured using existing input devices such as a keyboard, a pointing device (mouse, tablet, etc.), a button, a touch panel, etc. The input unit 12 is operated by a user when inputting a user's instruction to the first control terminal 10. The input unit 12 may be an interface for connecting the input device to the first control terminal 10. In this case, the input unit 12 inputs an input signal generated in the input device in response to a user's input to the first control terminal 10. The input unit 12 may be configured using a microphone and a voice recognition device. In this case, the input unit 12 acquires an acoustic signal generated by the user's speech, performs voice recognition on the words spoken by the user, and inputs character string information of the recognition result to the first control terminal 10. The voice recognition process may be executed by the control unit 15. The input unit 12 may be configured in any way as long as it is configured to input a user's instruction to the first control terminal 10.

[0016] The display unit 13 outputs information in a form that can be recognized by the user. The display unit 13 may be an image display device such as a liquid crystal display or an organic EL (Electro Luminescence) display. The display unit 13 may be an interface for connecting an image display device to the first control terminal 10. In this case, the display unit 13 generates a video signal for displaying image data and outputs the video signal to the image display device connected to itself. The display unit 13 may be configured as a touch panel integrated with the input unit 12.

[0017] The storage unit 14 is configured using a storage device such as a magnetic hard disk device or a semiconductor storage device. The storage unit 14 stores data used by the control unit 15. The storage unit 14 stores data required when the control unit 15 performs processing. The storage unit 14 functions as, for example, a mode information storage unit 141 and an instruction information storage unit 142.

[0018] The mode information storage unit 141 stores mode information. The mode information is, for example, information indicating whether the first control terminal 10 or the second control terminal 20 is in a linked mode. The mode information stored in the mode information storage unit 141 is read out as appropriate when the first control terminal 10 is controlled or the first control terminal 10 controls the second control terminal 20 in a linked manner.

[0019] For example, when the first control terminal 10 and the second control terminal 20 are in a linked mode, the second control terminal 20 may be controlled in a linked manner by an instruction input by a user to the first control terminal 10. Alternatively, the first control terminal 10 may be controlled in a linked manner by an instruction input by a user to the second control terminal 20. Also, for example, when the first control terminal 10 is not in the interlocking mode, that is, when the first control terminal 10 is in the non-interlocking mode, the second control terminal 20 is not controlled in an interlocking manner by an instruction input by a user to the first control terminal 10. Also, the first control terminal 10 does not have to be controlled in an interlocking manner by an instruction input by a user to the second control terminal 20.

[0020] In this embodiment, the change in mode information, i.e., switching between the linked mode and the non-linked mode in the first control terminal 10 or the second control terminal 20, may be performed, for example, by the user inputting an appropriate instruction via the input unit 12, or may be performed by the third update means 156 described later during a specific time period.

[0021] The mode information may be, for example, information indicating whether or not the entire plant interlocking system 1 is in the interlocking mode. In this embodiment, when the plant interlocking system 1 is in the interlocking mode, it means that all of the multiple control terminals included in the plant interlocking system 1 are in the interlocking mode. In the plant interlocking system 1, some of the control terminals may be in the interlocking mode and the rest in the non-interlocking mode. In such a case, the plant interlocking system 1 may be said to be in the semi-interlocking mode.

[0022] The instruction information storage unit 142 stores instruction information. The instruction information is, for example, information on instructions for causing the first control terminal 10 or the second control terminal 20 to control the functions of the plant P. The instruction information storage unit 142 stores records related to the control of the functions of the plant P as a log that can be referenced. The information stored in the instruction information storage unit 142 may be displayed on the display unit 13 so that it can be viewed by a user as appropriate. Hereinafter, in this embodiment, the functions of the plant P include the functions of the various devices described above provided in the plant P, as well as the functions of the plant interlocking system 1, i.e., the functions of the first control terminal 10 or the second control terminal 20.

[0023] In this embodiment, the functions of plant P controlled by the instruction information include, for example, (1) changing the mode information stored in the memory unit 14, (2) setting the control of the equipment of plant P to automatic, (3) updating the display of the status quantities of plant P, (4) setting the alarm values ​​of the equipment of plant P, (5) stopping the alarm buzzer, (6) changing the setting values ​​of the equipment of plant P, (7) displaying a screen showing the status quantities of plant P, and (8) setting the first control terminal 10.

[0024] (1) A change in the mode information stored in the storage unit 14 refers to a change in the mode information stored in the storage unit 14 of the first control terminal 10, for example, when the mode of the first control terminal 10 is changed from a non-linked mode to a linked mode, or from a linked mode to a non-linked mode. When the first control terminal 10 and the second control terminal 20 are in a linked mode, the mode of the second control terminal 20 may be changed in conjunction with the change in the mode of the first control terminal 10. Alternatively, the mode of the second control terminal 20 may be changeable by the first control terminal 10.

[0025] (2) Setting the control of the equipment of the plant P to automatic includes, for example, switching the control of equipment such as regulating valves, pumps, and valves provided in the plant P, which is any of the facilities described above, from manual control to automatic control. When the first control terminal 10 and the second control terminal 20 are in the linked mode, the first control terminal 10 controls the second control terminal 20 to cause the second control terminal 20 to make settings related to the control of the equipment of the plant P described above.

[0026] (3) Updating the display of state quantities of the plant P refers to appropriately updating information on state quantities such as the temperature, pressure, and valve opening of control valves and pumps equipped in the plant P and displaying the information on the display unit 13. When the first control terminal 10 and the second control terminal 20 are in the linked mode, the first control terminal 10 updates the information to be displayed on the display unit 13 of the second control terminal 20 in conjunction with updating the information to be displayed on the display unit 13 of the first control terminal 10.

[0027] (4) Setting the alarm values ​​of the equipment of the plant P means setting numerical values ​​for sounding an alarm buzzer with respect to state quantities such as the temperature, pressure, and valve opening of the control valves and pumps equipped in the plant P. In this embodiment, the alarm buzzer sounds when these state quantities exceed certain numerical alarm values ​​in order to prevent abnormalities from occurring in the plant P. The alarm buzzer is, for example, a warning sound sounded from a speaker or the like. In this embodiment, the alarm buzzer is simultaneously sounded in all the control terminals included in the plant interlocking system 1. When the first control terminal 10 and the second control terminal 20 are in an interlocking mode, the first control terminal 10 controls the second control terminal 20 to cause the second control terminal 20 to set an alarm value for the equipment of the plant P.

[0028] (5) Stopping an alarm buzzer refers to stopping an alarm buzzer issued in relation to state quantities such as temperature, pressure, valve opening, etc. of control valves and pumps equipped in the plant P. When the first control terminal 10 and the second control terminal 20 are in the linked mode, the first control terminal 10 stops the alarm buzzer issued in the second control terminal 20 in conjunction with stopping the alarm buzzer issued in the first control terminal 10.

[0029] (6) Changing the setting values ​​of the equipment of plant P refers to changing the setting values ​​related to state quantities such as the temperature, pressure, valve opening, etc. of the control valves and pumps equipped in plant P. In this embodiment, the setting values ​​related to these state quantities are upper limits for issuing an alert. The alert is issued, for example, before the equipment of plant P reaches a state where an alarm buzzer is sounded, so that the user can pay attention to the situation related to the state quantity. The alert is, for example, a warning sound issued from a speaker or the like, and may be a sound different from the alarm buzzer. The first control terminal 10 issues a warning in the first control terminal 10 when the state quantities exceed the set values ​​set in the first control terminal 10. In this embodiment, the upper limit values ​​for issuing a warning in this manner may be set individually in the first control terminal 10 and the second control terminal 20. In other words, even if the first control terminal 10 and the second control terminal 20 are in the linked mode, the set values ​​for these state quantities do not need to be set in the second control terminal 20 in a linked manner.

[0030] (7) Displaying a screen showing the state quantities of the plant P refers to displaying the latest information on state quantities such as the temperature, pressure, and valve opening of the control valves and pumps equipped in the plant P on the display unit 13 of the first control terminal 10, which is updated as needed. In this embodiment, the information displayed on the display unit 13 in this manner may be set individually in the first control terminal 10. In other words, even if the first control terminal 10 and the second control terminal 20 are in the linked mode, the information displayed on the display unit 13 in this manner does not need to be set linked in the second control terminal 20.

[0031] (8) The settings of the first control terminal 10 are, for example, user settings in the first control terminal 10. For example, the user settings in the first control terminal 10 are settings such as the size of characters displayed on the display unit 13 and the brightness of the screen. In this embodiment, such user settings may be set individually in the first control terminal 10. In other words, even if the first control terminal 10 and the second control terminal 20 are in a linked mode, such user settings do not need to be set in a linked manner in the second control terminal 20.

[0032] The control unit 15 is configured using a processor such as a CPU (Central Processing Unit) and a memory (main storage device). The control unit 15 functions as a display control means 151, a storage control means 152, a reception means 153, a first update means 154, a second update means 155, a third update means 156, an acquisition means 157, a setting means 158, a designation means 159, a transmission means 15A, and an alert means 15B by the processor executing a program. All or part of the functions of the control unit 15 may be realized using hardware such as an ASIC (Application Specific Integrated Circuit), a PLD (Programmable Logic Device), or an FPGA (Field Programmable Gate Array). The above program may be recorded in a computer-readable recording medium. The computer-readable recording medium is, for example, a portable medium such as a flexible disk, a magneto-optical disk, a ROM, a CD-ROM, or a semiconductor storage device (for example, an SSD: Solid State Drive), or a storage device such as a hard disk or a semiconductor storage device built into a computer system. The above program may be transmitted via an electric communication line.

[0033] The control unit 15 may execute, for example, an application installed in its own device (the first control terminal 10). A specific example of such an application is an application provided to the first control terminal 10 as a dedicated application for the plant interlocking system 1. Another specific example of such an application is a WEB browser application. Such an application may be installed in the first control terminal 10 in advance, or may be downloaded each time a judgment process is executed. For example, when the application is implemented as a WEB browser application, the first control terminal 10 may download and execute the application from a device (for example, the WEB server itself or another server) designated by the WEB server in response to the first control terminal 10 connecting to the specific WEB server. The control unit 15 operates according to the program of the application being executed.

[0034] The display control means 151 generates screen data based on the mode information and instruction information stored in the storage unit 14 and information on various state quantities transmitted from the devices of the plant P, and causes the display unit 13 to display the screen data. FIG. 3 shows a first example of screen data displayed on the display unit 13 by the display control means 151. As shown in FIG. FIG. 4 shows a second example of the screen data displayed on the display unit 13 by the display control means 151. As shown in FIG. FIG. 5 shows a third example of screen data displayed on the display unit 13 by the display control means 151. In FIG. 3, 4, and 5, the screen data displayed on the display unit 13 includes a transition image 13a and a non-transition image 13b. That is, the display control means 151 causes the display unit 13 to display, for example, the transition image 13a and the non-transition image 13b in association with each other.

[0035] The transition image 13a is an image that transitions according to a user's operation. Three examples of the contents displayed in the transition image 13a will be described below. The transition images 13a according to the three examples described below may be appropriately switched and displayed according to a user's operation. As shown in FIG. 3, the transition image 13a according to the first example includes an item image 13a1, a terminal display image 13a2, a transition linkage mode image 13a3, a linkage mode switching image 13a4, and a switching permission display image 13a5. The item image 13a1 is an image showing the contents of each image displayed in the transition image 13a according to the first example. In the example shown in Fig. 3, the item image 13a1 shows that, from the left, a terminal display image 13a2, a transition linkage mode image 13a3, a linkage mode switching image 13a4, and a switching permission display image 13a5 are displayed side by side.

[0036] The terminal display image 13a2 is an image showing individual information of the control terminal in the transition image 13a according to the first example. In the example shown in Fig. 3, the terminal display image 13a2 shows, from the top, the first control terminal 10 and the second control terminal 20. Note that, as shown by the above-mentioned item image 13a1, each of the following images is displayed with a separate row for each control terminal.

[0037] The transitional linkage mode image 13a3 is an image indicating whether the control terminal corresponding to each of the terminal display images 13a2 in the transitional image 13a according to the first example is in the linkage mode or the non-linkage mode. In the example shown in Fig. 3, the transitional linkage mode image 13a3 indicates, from above, that the first control terminal 10 is in the linkage mode and the second control terminal 20 is in the non-linkage mode. The transitional linkage mode image 13a3 may display, for example, the linkage mode or the non-linkage mode in different colors on the display unit 13.

[0038] The interlocking mode switching image 13a4 is a switch button for switching the control terminal to an interlocking mode or a non-interlocking mode in the transition image 13a according to the first example. In the example shown in Fig. 3, when "ON" is written on the interlocking mode switching image 13a4, it indicates that the control terminal is in an interlocking mode, and when "OFF" is written on the interlocking mode switching image 13a4, it indicates that the control terminal is in a non-interlocking mode. The interlocking mode switching image 13a4 can be switched to an interlocking mode or a non-interlocking mode by the user selecting the interlocking mode by clicking or tapping. 3, the linkage mode switching image 13a4 indicates, from the top, that the first control terminal 10 is in the linkage mode and the second control terminal 20 is in the non-linkage mode. The linkage mode switching image 13a4 may, for example, display the linkage mode or the non-linkage mode in different colors on the display unit 13. In this embodiment, the user may set the mode of each of the control terminals by selecting a linkage mode switching image 13a4 corresponding to each of the multiple control terminals.

[0039] The switching permission display image 13a5 indicates whether or not switching to the linked mode or the non-linked mode is permitted in each of the control terminals in the transition image 13a according to the first example. For example, when the switching permission display image 13a5 displays "permitted", it indicates that switching to the linked mode or the non-linked mode by linked control from another control terminal is permitted. When the switching permission display image 13a5 displays "not permitted", it indicates that switching to the linked mode or the non-linked mode by linked control from another control terminal is not permitted. 3, the switching permission display image 13a5 indicates that the first control terminal 10 does not permit mode switching in response to a switching instruction from another control terminal (e.g., the second control terminal 20), and that the second control terminal 20 permits mode switching in response to a switching instruction from another control terminal (e.g., the first control terminal 10). The switching permission display image 13a5 may display in different colors on the display unit 13 whether or not mode switching in response to a switching instruction from another control terminal is permitted. In addition, if mode switching due to a switching instruction from another control terminal is not permitted, as shown in Figure 3, the linked mode switching image 13a4 corresponding to the relevant control terminal (in the example shown in Figure 3, the linked mode switching image 13a4 corresponding to the first control terminal 10) may be grayed out and made unselectable. 3 shows a screen displayed on the display unit 13 of the first control terminal 10, but a common screen may also be displayed on the display unit 13 of the second control terminal 20. In this way, in the transition image 13a displayed on the display unit 13 of the second control terminal 20, the interlocking mode switching image 13a4 corresponding to the first control terminal 10 is grayed out and cannot be selected, so that the mode of the first control terminal 10 cannot be changed by the second control terminal 20. Even in such a case, for example, the first control terminal 10 may be able to change its own mode by selecting the interlocking mode image 13b3 of the non-transition image 13b described later.

[0040] As shown in FIG. 4, the transition image 13a according to the second example includes an item image 13a1, a terminal display image 13a2, a transition linkage mode image 13a3, and an alarm content image 13a6. The item image 13a1, the transition linkage mode image 13a3, and the terminal display image 13a2 are the same information as in the above-mentioned example 1. In the example shown in Fig. 4, the item image 13a1 is different in that it shows, from the left, the terminal display image 13a2, the transition linkage mode image 13a3, and the warning content image 13a6. The alarm content image 13a6 is an image showing the contents of the alarm buzzer issued by the alarm issuing means 15B described later. In this embodiment, as shown in FIG. 4, the display control means 151 causes the display unit 13 to display the transition interlocking mode image 13a3 and the interlocking mode image 13b3 described later in association with the alarm content image 13a6. In this embodiment, the display unit 13 may display these images in association with each other on the same screen, or may display these images sequentially on a screen displayed by scrolling, as long as the user can recognize the correspondence between these images. In the example shown in FIG. 4, the alarm content image 13a6 is a table showing the date and time of the alarm buzzer, the alarm content, the date and time of the buzzer stop operation, and the date and time of recovery. The date and time of the alarm is information showing the date and time when the alarm buzzer was issued. The alarm content is information showing the specific content, such as the state of the equipment of the plant P, related to the issued alarm buzzer. The buzzer stop operation date and time is information indicating the date and time when an operation to stop the alarm buzzer was performed after the alarm buzzer was sounded. The state of the equipment of the plant P does not have to be restored to its original state when the alarm buzzer is stopped by the operation. The restoration date and time is the date and time when the equipment of the plant P related to the alarm buzzer is restored to its original state after the alarm buzzer was sounded. Information for generating the alarm content image 13a6 (alarm information) may be stored in the instruction information storage unit 142 of the storage unit 14 as instruction information for sounding the alarm buzzer. The warning content image 13a6 may display the content of the issued caution in addition to the content of the issued warning.

[0041] 5, the transition image 13a according to the third example may include images and characters indicating information transmitted from the plant P. Specifically, as shown in Fig. 5, the transition image 13a according to the third example may display state quantity information 13a7, which is information regarding state quantities such as the temperature, pressure, and valve opening of a control valve or a pump included in the plant P. Information regarding various state quantities of the equipment of the plant P may be transmitted from the equipment of the plant P to the first control terminal 10 via the network 70. The information transmitted to the first control terminal 10 in this manner may be received by the communication unit 11 and acquired by an acquisition means 157 described later. 5, the transition image 13a according to the third example may display an instruction information log image 13a8. The instruction information log image 13a8 displays, on the display unit 13, an instruction input date and time indicating the date and time when the instruction information was input by the user, an instruction input content indicating the content of the instruction information stored in the instruction information storage unit 142, and an instruction input terminal indicating the control terminal where the instruction information was input, in association with each other. The instruction information log image 13a8 may display any other information related to the instruction. 5, various buttons for controlling the functions of the plant P may be displayed on the transition image 13a according to the third example. Specifically, for example, a button B1 for setting the control of the equipment of the plant P to manual or automatic, a button B2 for updating the display of the state quantity of the plant P, a button B3 for setting the alarm value or setting value of the equipment of the plant P, etc. may be displayed. Note that the display of the state quantity of the plant P may be updated by the button B2, or may be automatically updated at any time.

[0042] The non-transition image 13b is an image that does not transition in response to a user operation, in other words, the non-transition image 13b is an image that is always displayed on the display unit 13. FIG. 6 is a first example of an enlarged view of the non-transition image 13b. FIG. 7 is a second example of an enlarged view of the non-transitional image 13b. In the present embodiment, the non-transition image 13b may be located at the top of the screen data displayed on the display unit 13, as shown in Fig. 3. However, the non-transition image 13b may be appropriately located at any position in the screen data displayed on the display unit 13.

[0043] In this embodiment, the non-transition image 13b includes a control terminal image 13b1, a buzzer stop image 13b2, a linkage mode image 13b3, and a user authority image 13b4. In other words, the display control means 151 causes the display unit 13 to display the control terminal image 13b1, the buzzer stop image 13b2, the linkage mode image 13b3, and the user authority image 13b4 in association with each other in the non-transition image 13b. The control terminal image 13b1 is an image that indicates the identification information of the control terminal in the non-transition image 13b. In the non-transition image 13b shown in Fig. 6 or 7, the control terminal image 13b1 includes a first control terminal image 13b1a and a second control terminal image 13b1b. In this embodiment, the first control terminal image 13b1a corresponds to the first control terminal 10, and the second control terminal image 13b1b corresponds to the second control terminal 20.

[0044] The buzzer stop image 13b2 is a button that the user operates to stop the alarm buzzer that has been activated. When the user selects the buzzer stop image 13b2 by clicking or tapping, the alarm buzzer is stopped from being activated by the alarm activation means 15B of the control unit 15, which will be described later. For example, a buzzer stop image 13b2 corresponding to the first control terminal 10 is displayed on the display unit 13 of the first control terminal 10. In this embodiment, the alarm buzzer corresponding to the first control terminal 10 is deactivated in response to, for example, a user operation on the buzzer stop image 13b2 displayed on the display unit 13 of the first control terminal 10. Note that when the first control terminal 10 and the second control terminal 20 are in a linked mode, the alarm buzzer corresponding to the second control terminal 20 may be deactivated in conjunction with the deactivation of the alarm buzzer corresponding to the first control terminal 10. Depending on the buzzer stop image 13b2 of the first control terminal 10, the alert issued in the first control terminal 10 may be released.

[0045] The linkage mode image 13b3 is an image indicating whether or not at least the mode of the first control terminal 10 is the linkage mode, as shown in Fig. 6 or 7, for example. The linkage mode image 13b3 may indicate whether or not the mode of the second control terminal 20, in addition to the mode of the first control terminal 10, is the linkage mode. That is, the display control means 151 of the first control terminal 10 may cause the display unit 13 to display an image indicating the mode of the second control terminal 20, for example, based on mode information transmitted from the second control terminal 20. The linked mode image 13b3 includes a first control terminal linked mode image 13b3a and a second control terminal linked mode image 13b3b, as shown in FIG. 6 or 7. The first control terminal linked mode image 13b3a indicates whether the first control terminal 10 is in linked mode. The second control terminal linked mode image 13b3b indicates whether the second control terminal 20 is in linked mode. In the example shown in FIG. 6 or 7, the first control terminal linked mode image 13b3a and the second control terminal linked mode image 13b3b respectively indicate that the first control terminal 10 is in linked mode and the second control terminal 20 is in non-linked mode. In this embodiment, the display control means 151 causes the display unit 13 to display a control terminal image 13b1 corresponding to the first control terminal 10 in association with a first control terminal linkage mode image 13b3a, and also causes the display unit 13 to display a control terminal image 13b1 corresponding to the second control terminal 20 in association with a second control terminal linkage mode image 13b3b, as shown, for example, in FIG. 6 or FIG. 7.

[0046] In this embodiment, the mode of the first control terminal 10 or the second control terminal 20 is set to the linked mode or the non-linked mode in response to a user operation on the linked mode image 13b3. Specifically, this is as follows. That is, for example, the user may be able to switch the first control terminal 10 to the linked mode or non-linked mode by selecting the first control terminal linked mode image 13b3a by clicking, tapping, or the like. Also, for example, the user may be able to switch the second control terminal 20 to the linked mode or non-linked mode by selecting the second control terminal linked mode image 13b3b by clicking, tapping, or the like.

[0047] The user authority image 13b4 is an image indicating whether the authority of the user who has logged in to the first control terminal 10 is a predetermined authority. In this embodiment, when the authority of the user logging in to the first control terminal 10 is a predetermined authority, "ENG" is displayed in the user authority image 13b4 as shown in Fig. 6. In this embodiment, when the authority of the user logging in to the first control terminal 10 is equal to or higher than the predetermined authority, the user is permitted to control another control terminal (for example, the second control terminal 20) in the linked mode in a linked manner. Also, when the authority of the user logging in to the first control terminal 10 is not a predetermined authority, "VIEW" is displayed in the user authority image 13b4 as shown in FIG. 7. In this embodiment, when the authority of the user logging in to the first control terminal 10 is lower than the predetermined authority, the user is not permitted to control the first control terminal 10, and is permitted only to view. At this time, on the display unit 13 of the first control terminal 10, various images for controlling the first control terminal 10 may be grayed out and made inoperable. Also, when the first control terminal 10 in such a state is in the interlocking mode, the first control terminal 10 may be controlled in interlocking with another control terminal (for example, the second control terminal 20) in the interlocking mode. Depending on the authority of the user who logs in to the first control terminal 10, the user may only operate the first control terminal 10 and may not need to control the second control terminal 20 in conjunction with the first control terminal 10. In such a case, for example, the authority of the user who logs in to the first control terminal 10 is equal to or higher than a predetermined authority, and the first control terminal 10 is in a non-coordinated mode. In such a case, for example, "USER" may be displayed in the user authority image 13b4. In this embodiment, the authority for each user may be associated with the user's identification information and stored in the storage unit 14. In this way, the control unit 15 may display the user authority image 13b4 after confirming whether or not the logged-in user has the authority.

[0048] 2 stores, for example, mode information in the mode information storage unit 141 of the storage unit 14. In this embodiment, the storage control means 152 stores, for example, first control terminal information indicating the first control terminal 10 and the mode information in association with each other in the mode information storage unit 141 of the storage unit 14. The storage control means 152 may also store, in the mode information storage unit 141 of the storage unit 14, second control terminal information indicating the second control terminal 20 and the mode information in association with each other.

[0049] In this embodiment, the mode information stored in the storage unit 14 of the first control terminal 10 and used in the process of whether or not the first control terminal 10 controls the second control terminal 20 in a coordinated manner is mode information stored in association with the first control terminal information in the storage unit 14. In other words, whether or not the first control terminal 10 controls the second control terminal 20 in a coordinated manner is determined depending on whether the first control terminal 10 and the second control terminal 20 are in a coordinated mode.

[0050] For example, when the first control terminal 10 is in the interlocking mode and the second control terminal 20 is in the interlocking mode, when a user inputs a control instruction to the first control terminal 10, the second control terminal 20 is controlled in an interlocking manner. In a similar case, even if a user inputs a control instruction to the second control terminal 20, the first control terminal 10 is controlled in an interlocking manner. Also, for example, when the first control terminal 10 is in the linked mode and the second control terminal 20 is in the non-linked mode, the second control terminal 20 is not controlled in a linked manner even if the user inputs a control-related instruction to the first control terminal 10. In a similar case, the first control terminal 10 is not controlled in a linked manner even if the user inputs a control-related instruction to the second control terminal 20. In this manner, in this embodiment, whether each of the multiple control terminals is in the coordinated mode may be set individually for each of the multiple control terminals.

[0051] Furthermore, the storage control means 152 may store, for example, a log indicating that the receiving means 153 described below has received instruction information from the user in the storage unit 14. This may allow the user to later grasp details of control-related instructions input in the past. Furthermore, the memory control means 152 may store in the memory unit 14 a log indicating that an alarm buzzer has sounded in the plant P or that the mode information of the first control terminal 10 has been updated.

[0052] The receiving means 153 receives instruction information for causing the control terminal to control the functions of the plant P. Specifically, the receiving means 153 receives instruction information related to the control of the plant P, which is input by the user to the first control terminal 10 via the input unit 12. The instruction information input by the user may include, for example, information on an instruction to change an alarm value or a setting value of an apparatus of the plant P, and information on an instruction to stop an alarm buzzer that has been sounded. In other words, the receiving means 153 receives user operations on various images and buttons displayed on the above-mentioned transition image 13a or non-transition image 13b. Furthermore, the receiving means 153 may receive instruction information for sounding a warning or an alarm buzzer regarding a state quantity of an equipment of the plant P, based on an alarm value or a setting value set by a user. The instruction information for sounding a warning or an alarm buzzer may be transmitted, for example, by a transmitting means 15A described later. The information received by the receiving means 153 is converted into a command for controlling the function of the plant P. This allows the function of the plant P to be appropriately controlled. In addition, the information received by the receiving means 153 may be stored in the instruction information storage unit 142 of the storage unit 14.

[0053] The first update means 154 updates the mode information when the second control terminal 20 is controlled by the first control terminal 10. The first update means 154 operates, for example, in the following cases. That is, when the second control terminal 20 should not be controlled in conjunction with the first control terminal 10, if an instruction to control the second control terminal 20 in conjunction with the first control terminal 10 is given, the first update means 154 updates the mode information of the first control terminal 10 to the non-linked mode. Note that the decision of when the second control terminal 20 should not be controlled in conjunction with the first control terminal 10 may be made by the user, for example. In such a case, for example, information is transmitted from the second control terminal 20 to the first control terminal 10, indicating that the first control terminal 10 should be in the non-linked mode. When the first update means 154 receives the above-mentioned information from the second control terminal 20, it updates the mode information of the first control terminal 10 so that the mode becomes the non-linked mode. The above-mentioned information is transmitted from the second control terminal 20 by, for example, the user of the second control terminal 20 inputting appropriate information from the input unit 12 of the second control terminal 20.

[0054] The user's operation regarding the operation of the first update means 154 described above may be performed using the switching permission display image 13a5 in the transition image 13a shown in FIG. Specifically, for example, a user of the second control terminal 20 may set the switching permission display image 13a5 to either allow or disallow, thereby determining in advance whether or not to accept an instruction when given from the first control terminal 10 to control the second control terminal 20 in conjunction with the first control terminal 10. Alternatively, the user of the second control terminal 20 may use the switching permission display image 13a5 to decide whether or not to accept the instruction each time. That is, the user of the second control terminal 20 may appropriately switch the setting by the switching permission display image 13a5 as necessary. In this case, for example, the second control terminal 20 may notify the user that the instruction has been received by any method.

[0055] The second update means 155 updates the mode information when the reception means 153 receives instruction information. The first update means 154 operates in the following cases, for example. That is, in the case where the second control terminal 20 is to be controlled in conjunction with the first control terminal 10, when the receiving means 153 receives instruction information input by the user of the first control terminal 10, the second update means 155 updates the mode information of the first control terminal 10 to the linked mode. The second update means 155 operates, for example, when the user of the first control terminal 10 inputs instruction information via the input unit 12 while also inputting an instruction to control the second control terminal 20 in conjunction with the first control terminal 10. At this time, the user of the first control terminal 10 may decide whether or not to link the second control terminal 20 based on, for example, the importance of the instruction information to be input. For example, if the importance of an alarm buzzer issued simultaneously by multiple control terminals in the plant interlocking system 1 is low, the user of the first control terminal 10 may cancel the alarm buzzer issued by the second control terminal 20 in an interlocking manner. At this time, the second update means 155 may update the mode information of the first control terminal 10 to the interlocking mode in response to an instruction input from the user. Furthermore, if the importance of the alarm buzzer that has been sounded is high, the user of the first control terminal 10 may choose not to cancel the alarm buzzer sounded by the second control terminal 20 in conjunction with the first control terminal 10. At this time, the second update means 155 may update the mode information of the first control terminal 10 to the non-linked mode in response to an instruction input from the user. This may allow the user of the second control terminal 20 to easily notice the alarm buzzer with high importance. The user's operation regarding the operation of the second update means 155 described above may be performed using the linked mode switching image 13a4 in the transition image 13a shown in FIG. Specifically, for example, when the user uses the input unit 12 to input some instruction information, the user may appropriately set the mode using the linked mode switching image 13a4.

[0056] In this paragraph, for ease of explanation, the first control terminal 10 is provided in the second area A2, which is the location of the plant P to be controlled and monitored, and the second control terminal 20 is provided in the first area A1, which is an area remote from the plant P to be controlled and monitored. The third update means 156 updates the mode information so that the mode information indicates the linked mode for a predetermined time period in a day. The third update means 156 operates in the following cases, for example. Here, for example, in the second area A2 where the first control terminal 10 is provided, the plant P is constantly controlled and monitored by a user, whereas in the first area A1 where the second control terminal 20 is provided, the plant P may not be controlled or monitored by a user during a predetermined time period. The predetermined time period may be, for example, nighttime. That is, when it is nighttime in the first area A1, the plant P may not be remotely controlled or remotely monitored using the second control terminal 20. The predetermined time period is not limited to nighttime, and may be any other time period. The predetermined time period may be set arbitrarily by the user. When the first area A1 enters a predetermined time period, the third update means 156 updates the mode information of the first control terminal 10 to the linked mode. This enables the first control terminal 10 in the second area A2 to control the second control terminal 20 in the first area A1 in a linked manner. The third update means 156 may also update the mode information of the first control terminal 10 to the non-linked mode after the predetermined time period has passed.

[0057] The acquisition means 157 acquires information indicating the status of the functions of the plant P. This allows the user to grasp the status of the functions of the plant P. The acquisition means 157 may acquire information, for example, at any time, or periodically at a certain interval. The acquisition means 157 may acquire information, for example, when the user selects button B2 for updating the display of the state quantities of the plant P shown in FIG. 5. In this embodiment, the acquisition means 157 acquires information preferentially in the following cases. That is, the acquisition means 157 acquires information indicating the functional state of the plant P when the mode information stored in the storage unit 14 is updated. Specifically, when the mode information of the first control terminal 10 is updated from the linked mode to the non-linked mode, or when the mode information is updated from the non-linked mode to the linked mode, the acquisition means 157 acquires, for example, information on the state quantity of the plant P and information on whether or not the control of the equipment of the plant P is set to automatic. This contributes to reducing the possibility that the user will overlook a change in the state of the plant P.

[0058] The setting means 158 sets the mode of the first control terminal 10 to the linked mode. For example, the setting means 158 sets the mode of the first control terminal 10 to the linked mode by a user inputting, via the input unit 12 of the first control terminal 10, an instruction to set the first control terminal 10 to the linked mode. The setting of the mode by the setting means 158 may be performed, for example, when the user selects the linkage mode switching image 13a4 of the transition image 13a, or when the user selects the linkage mode image of the non-transition image 13b.

[0059] The designation means 159 designates the mode of a control terminal other than the first control terminal 10 itself to the linked mode. Specifically, for example, the designation means 159 included in the control unit 15 of the first control terminal 10 designates the mode of the second control terminal 20 to the linked mode. Also, depending on the designation means 159 included in the control unit 15 of the second control terminal 20, it may be possible to designate the mode of the first control terminal 10 to the linked mode. The mode is designated by the designation means 159, for example, when the user inputs an instruction to designate the second control terminal 20 to the linked mode via an input on the first control terminal 10. The mode may be designated by the designation means 159 based on such an input, for example, when the first control terminal 10 transmits an instruction to cancel the alarm buzzer sounded on the second control terminal 20. In this embodiment, for example, when the designation means 159 of the first control terminal 10 designates the mode of the second control terminal 20 to the linked mode, the display of the display unit 13 of the first control terminal 10 or the second control terminal 20 may be switched as appropriate. Specifically, the display of the transitional linkage mode image 13a3 of the transitional image 13a and the display of the linkage mode image 13b3 of the non-transitional image 13b may be switched as appropriate. Also, a log indicating that the mode of the second control terminal 20 has been designated by the first control terminal 10 may be stored in the storage unit 14. This may allow the user to grasp the designation of the mode afterwards.

[0060] The transmitting means 15A transmits instruction information for sounding an alert or an alarm buzzer in the first control terminal 10. The transmitting means 15A compares, for example, information acquired by the acquiring means 157 regarding state quantities such as the temperature, pressure, and valve opening of the control valves and pumps provided in the plant P with alarm values ​​and setting values ​​set by the user, and determines whether or not to transmit instruction information for sounding an alert or an alarm buzzer. The instruction information may be received by the receiving means 153.

[0061] When the receiving means 153 receives the instruction information from the transmitting means 15A, the issuing means 15B transmits voice data to the speaker of the first control terminal 10. This causes a warning or alarm buzzer to be issued in the first control terminal 10. The first control terminal 10 or the second control terminal 20 to the plant interlocking system 1 according to this embodiment are configured by the above components.

[0062] (Regarding the interlocking control of the second control terminal by the first control terminal) Next, the interlocking control of the second control terminal 20 by the first control terminal 10 will be described. As described above, when the first control terminal 10 is in the interlocking mode, the second control terminal 20 is interlocking controlled by the first control terminal 10. When the second control terminal 20 is interlockingly controlled by the first control terminal 10, information input by a user operating the input unit 12 of the first control terminal 10 may be transmitted to the second control terminal 20 via the network 70 by using, for example, the communication unit 11 of the first control terminal 10. The above-mentioned form may also be the same when the first control terminal 10 is interlockingly controlled by the second control terminal 20.

[0063] The following describes a form of information communication between the first control terminal 10 and the second control terminal 20 when the first control terminal 10 is in a linked mode and controls the second control terminal 20 in a linked manner by the first control terminal 10. That is, in this embodiment, when the first control terminal 10 controls the second control terminal 20 in conjunction with the second control terminal 20, it transmits a control command to the second control terminal 20 to cause the second control terminal 20 to control the functions of the plant P, and when the first control terminal 10 does not control the second control terminal 20 in conjunction with the second control terminal 20, it does not transmit a control command to the second control terminal 20. Hereinafter, a basic form of the interlocking control of the second control terminal 20 by the first control terminal 10 will first be described.

[0064] (Basic form of control of the first control terminal) FIG. 8 is a flow chart showing a basic form of control by the first control terminal 10. In FIG. As shown in FIG. 8, the control flow of the first control terminal 10 includes, for example, a reception step S0, a mode confirmation step S1, and a control step Ac. In the receiving step S0, an instruction is received from a user. In other words, the receiving step S0 is a step in which the receiving means 153 receives instruction information. When the receiving means 153 receives the instruction information in the receiving step S0, the process proceeds to a mode confirmation step S1. In the mode confirmation step S1, the mode of the first control terminal 10 is confirmed. If the mode information stored in the storage unit 14 in the mode confirmation step S1 indicates that the mode is the linked mode (step S1: YES), the first control terminal 10 operates in control step Ac to have the second control terminal 20 control the function in conjunction with the reception by the reception means 153 (step Ac1). At this time, whether the second control terminal 20 is controlled in conjunction may be determined depending on whether the second control terminal 20 is in the linked mode. If the mode information stored in the storage unit 14 does not indicate that the mode is the linked mode (step S1: NO), the first control terminal 10 does not control the second control terminal 20 in control step Ac even if the reception means 153 receives instruction information (step Ac2). In this embodiment, the interlocking control of the second control terminal 20 by the first control terminal 10 may be performed in accordance with any of the following modes in which additional elements are added to the basic mode described above. Three examples of the control of the second control terminal 20 by the first control terminal 10 will be described below.

[0065] (First example of control from the first control terminal) FIG. 9 is a flow chart showing a first example of the control of the first control terminal 10. In FIG. 9, the control flow according to the first example further includes a first function confirmation step SA1 between the above-mentioned mode confirmation step S1 and the control step Ac. The first function confirmation step SA1 is a step for confirming the function of the plant P to be controlled. As shown in FIG. 9, for example, if in a mode confirmation step S1 after the reception step S0, the mode information stored in the memory unit 14 indicates that the mode is a linked mode (S1: YES), and in a first function confirmation step SA1, the function of the plant P controlled by the instruction information received in the reception step S0 is any one of changing the mode information stored in the memory unit 14, setting the control of the equipment of the plant P to automatic, updating the display of the state quantities of the plant P, setting an alarm value for the equipment of the plant P, and stopping the alarm buzzer (SA1: YES), then in a control step Ac, the first control terminal 10 operates to cause the second control terminal 20 to control the function in conjunction with the reception by the reception means 153 (step Ac1). Then, if the mode information stored in the memory unit 14 in the mode confirmation step S1 indicates that the mode is the linked mode (S1: YES), and if the function of the plant P is not one of the above-mentioned in the first function confirmation step SA1 (SA1: NO), the first control terminal 10 does not operate in the control step Ac to have the second control terminal 20 control the function in conjunction with the acceptance by the acceptance means 153 (step Ac2).

[0066] (Second example of control from the first control terminal) FIG. 10 is a flow chart showing a second example of the control of the first control terminal 10. In FIG. 10, the control flow according to the second example further includes a second function confirmation step SB1 between the above-mentioned mode confirmation step S1 and the control step Ac. The second function confirmation step SB1 is a step for confirming the function of the plant P to be controlled. As shown in FIG. 10, for example, if in a mode confirmation step S1 after the reception step S0, the mode information stored in the memory unit 14 indicates that the mode is a linked mode (S1: YES), and in a second function confirmation step SB1, the function of the plant P controlled by the instruction information received in the reception step S0 is any one of changing the setting values ​​of the equipment of the plant P, displaying a screen showing the state quantities of the plant P, and settings of the first control terminal 10 (SB1: YES), then in a control step Ac, the first control terminal 10 does not operate to have the second control terminal 20 control the function in conjunction with the reception by the reception means 153 (step Ac2). Then, if the mode information stored in the memory unit 14 in the mode confirmation step S1 indicates that the mode is the linked mode (S1: YES), and if the function of the plant P is not one of the above-mentioned in the second function confirmation step SB1 (SB1: NO), the first control terminal 10 operates in control step Ac to have the second control terminal 20 control the function in conjunction with the acceptance by the acceptance means 153 (step Ac1).

[0067] (Third example of control from the first control terminal) FIG. 11 is a flow chart showing a third example of the control of the first control terminal 10. In FIG. 11, the control flow according to the third example further includes an authority confirmation step SC1 between the above-mentioned mode confirmation step S1 and control step Ac. The authority confirmation step SC1 is a step for confirming the authority of the user who logs in to the first control terminal 10. As shown in FIG. 11, for example, in the mode confirmation step S1 after the reception step S0, if the mode information stored in the storage unit 14 indicates that the mode is the interlocking mode (S1: YES), and if the authority of the user logging in to the first control terminal 10 is equal to or higher than the predetermined authority (SC1: YES) in the authority confirmation step SC1, the first control terminal 10 operates in control step Ac to have the second control terminal 20 control the function in conjunction with the reception by the reception means 153 (step Ac1). Then, in the mode confirmation step S1, if the mode information stored in the storage unit 14 indicates that the interlocking mode (S1: YES), and if the authority of the user logging in to the first control terminal 10 is lower than the predetermined authority in the authority confirmation step SC1 (SC1: NO), the first control terminal 10 does not operate in control step Ac to have the second control terminal 20 control the function in conjunction with the reception by the reception means 153 (step Ac2). In a third example, a user with a certain level of authority or more may, for example, use the first control terminal 10 to control the second control terminal 20 to change the setting of the control of the adjustment valve equipped in the plant P from manual to automatic. According to the above-mentioned embodiments, the first control terminal 10 according to the present embodiment performs the interlocking control of the second control terminal 20. Note that the first control terminal 10 may be interlocked with the second control terminal 20 according to the above-mentioned embodiments.

[0068] FIG. 12 is a diagram showing an outline of a hardware configuration example of an information processing device 90 applied to an embodiment. The information processing device 90 includes a processor 91, a main storage device 92, a communication interface 93, an auxiliary storage device 94, an input / output interface 95, and an internal bus 96. The processor 91, the main storage device 92, the communication interface 93, the auxiliary storage device 94, and the input / output interface 95 are communicably connected to each other via the internal bus 96. The information processing device 90 may be applied to, for example, the first control terminal 10 and the second control terminal 20. In this case, for example, the communication unit 11 may be configured using the communication interface 93. For example, the storage unit 14 may be configured using the auxiliary storage device 94. In addition, the control unit 15 may be configured using the processor 91 and the main storage device 92.

[0069] As described above, according to the plant interlocking system 1 according to the present embodiment, when the mode information stored in the storage unit 14 indicates the interlocking mode, the first control terminal 10 controls the second control terminal 20 to control the functions of the plant P in conjunction with the reception of instruction information by the reception means 153. When the mode information stored in the storage unit 14 does not indicate the interlocking mode, the first control terminal 10 does not control the second control terminal 20 even if the reception means 153 receives instruction information. This makes it possible to appropriately control the second control terminal 20 in conjunction with the reception of instruction information by the first control terminal 10 depending on whether the mode information stored in the storage unit 14 indicates the interlocking mode or not. Therefore, it is possible to efficiently control the second control terminal 20 in conjunction with the reception of instruction information by the first control terminal 10.

[0070] Furthermore, when the mode information stored in the storage unit 14 indicates that the mode is the interlocking mode, and the function of the plant P is one of changing the mode information stored in the storage unit 14, setting the control of the equipment of the plant P to automatic, and updating the display of the state quantity of the plant P, the first control terminal 10 controls the second control terminal 20 to control the function of the plant P in conjunction with the reception by the reception means 153. When the mode information stored in the storage unit 14 indicates that the mode is the interlocking mode, and the function of the plant P is not one of changing the mode information stored in the storage unit 14, setting the control of the equipment of the plant P to automatic, and updating the display of the state quantity of the plant P, the first control terminal 10 does not control the second control terminal 20 to control the function of the plant P in conjunction with the reception by the reception means 153. When the mode information stored in the storage unit 14 does not indicate the interlocking mode, the first control terminal 10 does not control the second control terminal 20 even if the reception means 153 receives instruction information. This makes it possible to control the second control terminal 20 appropriately depending on whether the mode information stored in the storage unit 14 is the interlocking mode and on the functions of the plant P, for example.

[0071] Furthermore, when the mode information stored in the storage unit 14 indicates that the mode is the interlocking mode, and the function of the plant P is any one of changing the setting values ​​of the equipment of the plant P, displaying a screen showing the state quantities of the plant P, and setting of the first control terminal 10, the first control terminal 10 does not control the second control terminal 20 to have the second control terminal 20 control the function of the plant P in conjunction with the acceptance by the acceptance means 153. When the mode information stored in the storage unit 14 indicates that the mode is the interlocking mode, and the function of the plant P is not any one of changing the setting values ​​of the equipment of the plant P, displaying a screen showing the state quantities of the plant P, and setting of the first control terminal 10, the first control terminal 10 controls the second control terminal 20 to have the second control terminal 20 control the function of the plant P in conjunction with the acceptance by the acceptance means 153. When the mode information stored in the storage unit 14 does not indicate the interlocking mode, and the function of the plant P is not any one of changing the setting values ​​of the equipment of the plant P, displaying a screen showing the state quantities of the plant P, and setting of the first control terminal 10, the first control terminal 10 does not control the second control terminal 20 even if the acceptance means 153 accepts instruction information. This makes it possible to control the second control terminal 20 appropriately depending on whether the mode information stored in the storage unit 14 is the interlocking mode and on the functions of the plant P, for example.

[0072] Moreover, when the mode information stored in the storage unit 14 indicates that the mode is the interlocking mode and the authority of the user who logs in to the first control terminal 10 is a predetermined authority, the first control terminal 10 controls the second control terminal 20 to control the function of the plant P in conjunction with the reception by the reception means 153. When the mode information stored in the storage unit 14 indicates that the mode is the interlocking mode and the authority of the user who logs in to the first control terminal 10 is not a predetermined authority, the first control terminal 10 does not control the second control terminal 20 to control the function of the plant P in conjunction with the reception by the reception means 153. When the mode information stored in the storage unit 14 does not indicate the interlocking mode, the first control terminal 10 does not control the second control terminal 20 even if the reception means 153 receives instruction information. Thereby, for example, the second control terminal 20 can be appropriately controlled according to whether the mode information stored in the storage unit 14 is the interlocking mode or not and the authority of the logged-in user.

[0073] Moreover, the storage control means 152 associates the first control terminal information indicating the first control terminal 10 with the mode information and stores it in the storage unit 14, and also associates the second control terminal information indicating the second control terminal 20 with the mode information and stores it in the storage unit 14. The mode information stored in the storage unit 14 and used in the process of whether the first control terminal 10 controls the second control terminal 20 is the mode information stored in the storage unit 14 in association with the first control terminal information. As a result, for example, by individually setting the interlocking mode in each of the control terminals including the first control terminal 10 and the second control terminal 20, more appropriate control can be performed for each control terminal. In other words, more detailed interlocking control can be performed.

[0074] Furthermore, when the first control terminal 10 controls the second control terminal 20, it transmits a control command to the second control terminal 20 to cause the second control terminal 20 to control the functions of the plant P, and when the first control terminal 10 does not control the second control terminal 20, it does not transmit a control command to the second control terminal 20. This allows the first control terminal 10 to control the second control terminal 20 more reliably.

[0075] The control device further includes a first update means 154 for updating the mode information when the second control terminal 20 is controlled by the first control terminal 10. This makes it possible to determine whether or not to set the second control terminal 20 to the linked mode when the second control terminal 20 is controlled by the first control terminal 10, for example. This makes it possible to perform control that is more in line with the user's intention.

[0076] The device further includes a second update means 155 for updating the mode information when the reception means 153 receives instruction information. This allows, for example, when the first control terminal 10 receives instruction information, to determine whether or not to control the second control terminal 20 in conjunction with the instruction information in accordance with the instruction information. This allows control to be performed in accordance with the user's intention.

[0077] The device further includes a third update means 156 for updating the mode information so that the mode information indicates the linked mode during a predetermined time period of the day. This makes it possible to determine whether or not to control the second control terminal 20 in a linked manner, for example, depending on the time period of the day.

[0078] Furthermore, the storage control means 152 stores a log indicating that the receiving means 153 has received the instruction information in the storage unit 14. This allows, for example, the reason why the second control terminal 20 has been controlled in an interlocking manner to be checked after the fact. This further improves convenience.

[0079] The system further includes an acquisition means 157 for acquiring information indicating the functional status of the plant P when the mode information stored in the storage unit 14 is updated. This allows the mode information to be updated appropriately according to the functional status of the plant P, for example. It also makes it easier to check in detail the information indicating the functional status of the plant P before and after the mode information is updated. This reduces the possibility of overlooking a change in the functional status of the plant P, for example.

[0080] Furthermore, the first control terminal 10 includes a designation means 159 for designating the mode of the second control terminal 20 to the linked mode. This allows the first control terminal 10 to designate the mode of the second control terminal 20.

[0081] Second embodiment Next, a plant interlocking system according to a second embodiment of the present disclosure will be described. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and their description will be omitted, with only the differences being described. In the second plant interlocking system (plant interlocking system 1) according to the second embodiment, one of the multiple control terminals can be set to semi-interlocking mode. The following describes an example in which the first control terminal 10 is set to the semi-interlocking mode. Note that in the second plant interlocking system, the second control terminal 20 may also be set to the semi-interlocking mode in a similar manner.

[0082] In the second embodiment, the mode information of the first control terminal 10 indicates whether or not it is in the linked mode, and whether or not it is in the semi-linked mode. Also, in the second embodiment, the setting means 158 of the control unit 15 sets the mode of the first control terminal 10 to the linked mode, the semi-linked mode, or the non-linked mode. In the second embodiment, the transition linked mode image 13a3 and the linked mode image 13b3 at least indicate whether the mode of the first control terminal 10 is the linked mode, the semi-linked mode, or the non-linked mode. In the second embodiment, the setting means 158 sets the mode of the first control terminal 10 to the linked mode, semi-linked mode, or non-linked mode, for example, by a user inputting an instruction to set the first control terminal 10 to the linked mode or semi-linked mode via input on the first control terminal 10. When the mode of the first control terminal 10 is the interlocking mode, the mode information stored in the mode information storage unit 141 of the storage unit 14 by the storage control means 152 indicates that it is the interlocking mode, which is similar to the first embodiment. In the second embodiment, when the mode of the first control terminal 10 is the semi-interlocking mode, the mode information stored in the mode information storage unit 141 of the storage unit 14 by the storage control means 152 indicates that it is the semi-interlocking mode.

[0083] In the second embodiment, when the mode information stored in the storage unit 14 indicates the linked mode, the first control terminal 10 controls the second control terminal 20 to control the functions of the plant P in linkage with the reception by the reception means 153. This is the same as in the first embodiment.

[0084] In the second embodiment, when the mode information stored in the memory unit 14 indicates that the first control terminal 10 is in the semi-linked mode, if the first control terminal 10 is installed within the same premises as the second control terminal 20, the first control terminal 10 controls the second control terminal 20 to control the function in conjunction with acceptance by the acceptance means 153, and if the first control terminal 10 is not installed within the same premises as the second control terminal 20, even if the acceptance means 153 accepts instruction information, the first control terminal 10 does not control the second control terminal 20 to control the function. The semi-interlocking mode of the first control terminal 10 will be described below on the assumption that the second control terminal 20 is provided in the second area A2 including the site of the plant P. That is, when the first control terminal 10 is in the semi-interlocking mode, if the first control terminal 10 is also provided in the same second area A2 as the second control terminal 20, the first control terminal 10 functions in the above-mentioned interlocking mode. When the first control terminal 10 is in the semi-interlocking mode, if the first control terminal 10 is provided in a location away from the second area A2, the first control terminal 10 functions in the above-mentioned non-interlocking mode.

[0085] Such a semi-linked mode is effective, for example, when the first control terminal 10 is a portable terminal such as a tablet or smartphone, and moves between the second area A2 and a location other than the second area A2 (for example, the first area A1). For this reason, the semi-interlocking mode may be set, for example, when the first control terminal 10 is a portable terminal such as a tablet, a smartphone, etc. Alternatively, without being limited thereto, the semi-interlocking mode may be set in any control terminal in the second plant interlocking system.

[0086] In the second embodiment, when the mode information stored in the storage unit 14 indicates neither the synchronized mode nor the semi-synchronized mode, that is, when the first control terminal 10 is in the non-synchronized mode, the first control terminal 10 does not control the second control terminal 20 even if the reception means 153 receives instruction information. This is the same as in the first embodiment. The first control terminal 10 or the second control terminal 20 to the second plant interlocking system according to the second embodiment is configured by the above-mentioned components. In the second embodiment, the flows shown in the above-mentioned Figures 8 to 10 may be performed in a linked mode or a non-linked mode as appropriate, depending on whether the location where the first control terminal 10 is installed is the second area A2 or a location other than the second area A2.

[0087] As described above, according to the second plant interlocking system according to the second embodiment, when the mode information stored in the storage unit 14 indicates an interlocking mode, the first control terminal 10 controls the second control terminal 20 to control the function of the plant P in conjunction with the reception by the reception means 153. When the mode information stored in the storage unit 14 indicates a semi-interlocking mode, the first control terminal 10 controls the second control terminal 20 to control the function of the plant P in conjunction with the reception by the reception means 153 if the first control terminal 10 is installed in the same premises as the second control terminal 20, and does not control the second control terminal 20 to control the function of the plant P even if the reception means 153 receives instruction information if the first control terminal 10 is not installed in the same premises as the second control terminal 20. Then, when the mode information stored in the storage unit 14 indicates neither the linked mode nor the semi-linked mode, the first control terminal 10 does not control the second control terminal 20 even if the reception means 153 receives instruction information. This makes it possible to appropriately control the second control terminal 20 in conjunction with the reception of instruction information from the first control terminal 10, depending on, for example, whether the mode information stored in the storage unit 14 indicates the linked mode or the semi-linked mode, and on the installation location of the first control terminal 10. This makes it possible to efficiently control the second control terminal 20 in conjunction with the first control terminal 10.

[0088] The system further includes a setting unit for setting the mode of the first control terminal 10 to the linked mode or the semi-linked mode, whereby the mode of the first control terminal 10 can be set to the linked mode or the semi-linked mode.

[0089] Third embodiment Next, a plant interlocking system (third plant interlocking system 3) according to a third embodiment of the present disclosure will be described with reference to FIG. In the second embodiment, the same components as those in the first and second embodiments are denoted by the same reference numerals, and their description will be omitted, with only the differences being described. FIG. 13 is a schematic block diagram showing a system configuration of a third plant interlocking system 3 according to the third embodiment. As shown in Fig. 13, the third plant interlocking system 3 according to the third embodiment includes six control terminals: a first control terminal 10, a second control terminal 20, a third control terminal 30, a fourth control terminal 40, a fifth control terminal 50, and a sixth control terminal 60. As shown in Fig. 13, in the third embodiment, the first control terminal 10, the third control terminal 30, the fourth control terminal 40, and the sixth control terminal 60 are provided in a first area A1, and the second control terminal 20 and the fifth control terminal 50 are provided in a second area A2.

[0090] In the third embodiment, the semi-interlocking mode can be set in one of the multiple control terminals, as in the second embodiment. Details of the semi-interlocking mode in the third embodiment are the same as those in the second embodiment. In the third embodiment, the first control terminal 10, the second control terminal 20, and the third control terminal 30 are in a linked mode, the fourth control terminal 40 and the fifth control terminal 50 are in a semi-linked mode, and the sixth control terminal 60 is in a non-linked mode. In this embodiment, a group of control terminals that are controlled in a coordinated manner due to being in the coordinated mode may be referred to as a coordinated mode group. That is, in the third embodiment, the first control terminal 10, the second control terminal 20, and the third control terminal 30 may be said to belong to the coordinated mode group. Similarly, the fourth control terminal 40 and the fifth control terminal 50, which are in the semi-coordinated mode, may be said to belong to the semi-coordinated mode group, and the sixth control terminal 60, which is in the non-coordinated mode, may be said to belong to the non-coordinated mode group.

[0091] The first control terminal 10, the second control terminal 20, and the third control terminal 30, which belong to the above-mentioned linked mode group, are controlled in linkage with the operations of the other control terminals, regardless of their installation locations. The sixth control terminal 60 belonging to the non-linked mode group described above is not controlled in conjunction with the operations of other control terminals, regardless of the installation location.

[0092] In the third embodiment, the fourth control terminal 40 and the fifth control terminal 50 belonging to the semi-linked mode groups described above are controlled as follows. That is, for example, in the semi-interlocking mode, the fourth control terminal 40 provided in the first area A1 functions as a non-interlocking mode. That is, in the third embodiment, the fourth control terminal 40 is not controlled in conjunction with the operation of the other control terminals. Note that such control is, for example, when the second control terminal 20 is operated by the user. In addition, in the semi-interlocking mode, the fifth control terminal 50 provided in the second area A2 functions as an interlocking mode terminal. That is, in the third embodiment, the fifth control terminal 50 is controlled in conjunction with the operation of the other control terminals. Note that, in the semi-interlocking mode, when there are multiple control terminals provided in the second area A2, the control terminals in the semi-interlocking mode provided in the second area may be controlled in conjunction with each other. Note that such control is, for example, when the second control terminal 20 is operated by a user.

[0093] The technical scope of the present disclosure is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present disclosure. For example, although it has been described that the first control terminal 10 is provided in the first area A1 and the second control terminal 20 is provided in the second area A2, each of the first control terminal 10 and the second control terminal 20 may be provided in either the first area A1 or the second area A2. Also, in addition to the first control terminal 10 and the second control terminal 20, any number of more control terminals may be provided. In addition to the various types of information described above, any other information may be appropriately displayed on the display unit 13. For example, the display unit 13 may display a model diagram of the plant P in the transition image 13a. Furthermore, the functions of the plant are not limited to those described above, but may include any of a variety of functions, and whether or not to control the control terminal in an interlocking manner may be determined based on such functions. Furthermore, the criteria for determining whether or not to control the control terminal in an interlocking manner are not limited to those described above, and any criteria may be set. Furthermore, the control unit 15 does not necessarily have to include the first updating means 154 , the second updating means 155 , the third updating means 156 , the obtaining means 157 , the setting means 158 , and the designation means 159 . Furthermore, the storage control means 152 does not need to store in the storage unit 14 a log indicating that the instruction information has been received.

[0094] In addition, within the scope of the present disclosure, the components in the above-described embodiments may be replaced with well-known components as appropriate, and the above-described modified examples may be combined as appropriate.

[0095] (Additional Note) The plant interlocking system according to the embodiment can be understood, for example, as follows.

[0096] <1> A plant interlocking system according to one embodiment of the present disclosure is a plant interlocking system having a plurality of control terminals used to control the plant, comprising a first control terminal which is one of the plurality of control terminals, a second control terminal which is one of the plurality of control terminals and different from the first control terminal, and a memory control means for storing mode information indicating whether or not the interlocking mode is in a memory unit, wherein the first control terminal includes a reception means for receiving instruction information to cause the control terminal to control a function of the plant, and when the mode information stored in the memory unit indicates the interlocking mode, the first control terminal controls the second control terminal to cause the second control terminal to control the function in conjunction with the reception by the reception means, and when the mode information stored in the memory unit does not indicate the interlocking mode, the reception means does not control the second control terminal even if it receives the instruction information.

[0097] According to the above plant interlocking system, when the mode information stored in the storage unit indicates the interlocking mode, the first control terminal controls the second control terminal to control the functions of the plant in conjunction with the reception of instruction information by the reception means. When the mode information stored in the storage unit does not indicate the interlocking mode, the first control terminal does not control the second control terminal even if the reception means receives instruction information. This makes it possible to appropriately control the second control terminal in conjunction with the reception of instruction information from the first control terminal depending on whether the mode information stored in the storage unit indicates the interlocking mode or not. Therefore, it is possible to efficiently control the second control terminal in conjunction with the first control terminal.

[0098] <2> A plant interlocking system according to one aspect of the present disclosure is a plant interlocking system including a plurality of control terminals used to control a plant, the plant interlocking system including a first control terminal which is one of the plurality of control terminals, a second control terminal which is one of the plurality of control terminals and different from the first control terminal, and a storage control means for storing mode information in a storage unit indicating whether or not a synchronization mode and whether or not a semi-synchronization mode is in a synchronization mode, the first control terminal including a reception means for receiving instruction information for causing the control terminal to control a function of the plant, and when the mode information stored in the storage unit indicates the synchronization mode, the first control terminal controls the second control terminal to control the function in synchronization with the reception by the reception means. The present invention is characterized in that, when the mode information stored in the memory unit indicates the semi-linked mode, if the first control terminal is installed within the same premises as the second control terminal, the second control terminal is controlled in conjunction with acceptance by the reception means to have the second control terminal control the function, and when the first control terminal is not installed within the same premises as the second control terminal, even if the reception means accepts the instruction information, the reception means does not control the second control terminal to have the second control terminal control the function, and when the mode information stored in the memory unit indicates neither the linked mode nor the semi-linked mode, the reception means does not control the second control terminal even if it accepts the instruction information.

[0099] According to the above plant interlocking system, when the mode information stored in the storage unit indicates an interlocking mode, the first control terminal controls the second control terminal in conjunction with the reception by the reception means to have the second control terminal control the functions of the plant. When the mode information stored in the storage unit indicates a semi-interlocking mode, if the first control terminal is installed in the same premises as the second control terminal, the first control terminal controls the second control terminal in conjunction with the reception by the reception means to have the second control terminal control the functions of the plant, and when the first control terminal is not installed in the same premises as the second control terminal, even if the reception means receives instruction information, the first control terminal does not control the second control terminal even if the reception means receives instruction information, when the mode information stored in the storage unit indicates neither the interlocking mode nor the semi-interlocking mode. This allows the second control terminal to be appropriately controlled in conjunction with the reception of instruction information from the first control terminal, depending on, for example, whether the mode information stored in the storage unit indicates an interlocking mode or a semi-interlocking mode, and the installation location of the first control terminal. Therefore, it is possible to efficiently control the second control terminal in conjunction with the first control terminal.

[0100] <3> A plant interlocking system according to one aspect of the present disclosure is a plant interlocking system including a plurality of control terminals used to control a plant, the plant interlocking system including a first control terminal which is one of the plurality of control terminals, a second control terminal which is one of the plurality of control terminals and different from the first control terminal, and a storage control means for storing mode information indicating whether or not an interlocking mode is being set in a storage unit, the first control terminal including a receiving means for receiving instruction information for causing the control terminal to control a function of the plant, the first control terminal including a receiving means for receiving instruction information indicating that the mode information stored in the storage unit is the interlocking mode, and changing the mode information stored in the storage unit, the second control terminal is controlled to have the second control terminal control the function in conjunction with the reception by the receiving means when the instruction information is one of: setting control of an equipment of the plant to automatic; and updating a display of a state quantity of the plant; if the mode information stored in the memory unit indicates the interlocking mode and is not one of the above, the second control terminal is not controlled to have the second control terminal control the function in conjunction with the reception by the receiving means; and if the mode information stored in the memory unit does not indicate the interlocking mode, the second control terminal is not controlled even if the receiving means receives the instruction information.

[0101] According to the above plant interlocking system, the first control terminal controls the second control terminal to control the function of the plant in cooperation with the reception by the reception means when the mode information stored in the storage unit indicates that the mode is the interlocking mode and the function of the plant is one of changing the mode information stored in the storage unit, setting the control of the plant equipment to automatic, and updating the display of the state quantity of the plant. The first control terminal does not control the second control terminal to control the function of the plant in cooperation with the reception by the reception means when the mode information stored in the storage unit indicates that the mode is the interlocking mode and the function of the plant is not one of changing the mode information stored in the storage unit, setting the control of the plant equipment to automatic, and updating the display of the state quantity of the plant. And, when the mode information stored in the storage unit does not indicate the interlocking mode, the first control terminal does not control the second control terminal even if the reception means receives the instruction information. Thereby, for example, it is possible to appropriately control the second control terminal according to whether the mode information stored in the storage unit is the interlocking mode or not, and the function of the plant.

[0102] <4> A plant interlocking system according to one aspect of the present disclosure is a plant interlocking system including a plurality of control terminals used to control a plant, the plant interlocking system including a first control terminal which is one of the plurality of control terminals, a second control terminal which is one of the plurality of control terminals and different from the first control terminal, and a storage control means for storing mode information indicating whether or not an interlocking mode is being set in a storage unit, the first control terminal including a receiving means for receiving instruction information for causing the control terminal to control a function of the plant, the first control terminal receiving means for receiving instruction information for causing the control terminal to control a function of the plant when the mode information stored in the storage unit indicates that the interlocking mode is set in the interlocking mode and the function is to change a setting value of an equipment of the plant, The present invention is characterized in that, if the instruction information is one of the display of a screen showing a state quantity of the plant and the settings of the first control terminal, the second control terminal is not controlled to have the second control terminal control the function in conjunction with the acceptance by the receiving means, and if the mode information stored in the memory unit indicates that it is the linked mode and is not one of the above, the second control terminal is controlled to have the second control terminal control the function in conjunction with the acceptance by the receiving means, and if the mode information stored in the memory unit does not indicate the linked mode, the second control terminal is not controlled even if the receiving means accepts the instruction information.

[0103] According to the above plant interlocking system, when the mode information stored in the storage unit indicates the interlocking mode and the function of the plant is any one of changing the setting values ​​of the equipment of the plant, displaying a screen showing the state quantity of the plant, and the setting of the first control terminal, the first control terminal does not control the second control terminal to control the function of the plant in cooperation with the reception by the reception means. When the mode information stored in the storage unit indicates the interlocking mode and the function of the plant is not any one of changing the setting values ​​of the equipment of the plant, displaying a screen showing the state quantity of the plant, and the setting of the first control terminal, the first control terminal controls the second control terminal to control the function of the plant in cooperation with the reception by the reception means. And, when the mode information stored in the storage unit does not indicate the interlocking mode, the first control terminal does not control the second control terminal even if the reception means receives the instruction information. Thereby, for example, it is possible to appropriately control the second control terminal according to whether the mode information stored in the storage unit is the interlocking mode or not, and the function of the plant.

[0104] <5> A plant interlocking system according to one aspect of the present disclosure is a plant interlocking system including a plurality of control terminals used to control a plant, the plant interlocking system including a first control terminal which is one of the plurality of control terminals, a second control terminal which is one of the plurality of control terminals and is different from the first control terminal, and a storage control means for storing mode information in a storage unit indicating whether or not an interlocking mode is in effect, the first control terminal including a receiving means for receiving instruction information for causing the control terminal to control a function of the plant, the first control terminal including a receiving means for receiving instruction information indicating that the mode information stored in the storage unit is the interlocking mode, and a user logging in to the first control terminal When the user's authority is a specified authority, the second control terminal is controlled in conjunction with acceptance by the receiving means to have the second control terminal control the function; when the mode information stored in the memory unit indicates that the linked mode is selected and when the authority of the user logging in to the first control terminal is not a specified authority, the second control terminal is not controlled in conjunction with acceptance by the receiving means to have the second control terminal control the function; and when the mode information stored in the memory unit does not indicate the linked mode, the receiving means does not control the second control terminal even if it accepts the instruction information.

[0105] According to the above plant interlocking system, when the mode information stored in the storage unit indicates that the interlocking mode is selected and the user who logs in to the first control terminal has a predetermined authority, the first control terminal controls the second control terminal to control the functions of the plant in response to the reception by the reception means. When the mode information stored in the storage unit indicates that the interlocking mode is selected and the user who logs in to the first control terminal does not have a predetermined authority, the first control terminal does not control the second control terminal to control the functions of the plant in response to the reception by the reception means. When the mode information stored in the storage unit does not indicate the interlocking mode, the first control terminal does not control the second control terminal even if the reception means receives instruction information. This makes it possible to control the second control terminal appropriately depending on, for example, whether the mode information stored in the storage unit is selected as the interlocking mode or not and the authority of the logged-in user.

[0106] <6> the above <1> from <5> In the plant interlocking system according to any one of the above aspects, the storage control means may associate first control terminal information indicating the first control terminal with the mode information and store it in the storage unit, and may associate second control terminal information indicating the second control terminal with the mode information and store it in the storage unit, and the mode information stored in the storage unit and used in processing whether the first control terminal controls the second control terminal is the mode information stored in the storage unit in association with the first control terminal information.

[0107] The storage control means stores in the storage unit the first control terminal information indicating the first control terminal and the mode information in association with each other, and stores in the storage unit the second control terminal information indicating the second control terminal and the mode information in association with each other.

[0116] <11> the above <1> from <10> In the plant interlocking system according to any one of the above aspects, a configuration may be adopted in which the memory control means stores in the memory unit a log indicating that the receiving means has received the instruction information.

[0117] In addition, the storage control means stores in the storage unit a log indicating that the receiving means has received the instruction information. This allows, for example, the reason why the second control terminal has been controlled in conjunction to be checked after the fact. This further improves convenience.

[0118] <12> the above <1> from <11> In the plant interlocking system according to any one of the above aspects, a configuration may be adopted which further includes an acquisition means for acquiring information indicating a status of the function when the mode information stored in the memory unit is updated.

[0119] The system further includes an acquisition unit for acquiring information indicating the functional status of the plant when the mode information stored in the storage unit is updated. This makes it possible to update the mode information appropriately according to the functional status of the plant, for example. It also makes it easier to check in detail the information indicating the functional status of the plant before and after the mode information is updated. This makes it possible to reduce the possibility of overlooking a change in the functional status of the plant, for example.
