Buttons, a printout button for printing out, a tag button for giving a highlight mark to a page, a logout button for logging out, and the like. When detecting the selection of each operation button, that is, the touch of each operation button, the procedure manual display control unit 32 executes the function assigned to the operation button.

  Although the second procedure window has the layout described above, the display of the left page ML and the right page MR is performed in a display mode (continuous display) for displaying successive pages of the same electronic procedure manual M described in FIG. Mode). For example, when the operator starts two electronic procedure manuals M, the procedure manual display control unit 32 may display different electronic procedure manuals M on the left page ML and the right page MR ( Independent display mode).

  In addition, when the procedure step displayed on the left page ML is provided with a foldout page, the procedure manual display control unit 32 may display the foldout page on the right page MR (foldout display mode). ). FIG. 7 is a diagram illustrating an example of the display of the fold-out page of the procedure manual display unit. As shown in FIG. 7, the fold-out page (folding page) is a page displayed on the right page MR and has a fold-out image M7. The fold-out image M7 indicates the types of parameters that need to be monitored (confirmed) immediately when the procedure steps displayed on the left page ML are executed. A fold-out page is provided for each procedure step, and some procedural steps do not have a fold-out page.

  When the procedure step displayed on the left page ML is provided with a fold-out page, the procedure manual display control unit 32 displays the fold-out page on the right page MR without any operation by the operator. However, when there is no operation by the operator, the procedure manual display control unit 32 may be in the continuous display mode. In this case, the procedure manual display control unit 32 causes the operator to perform a display indicating that the fold-out page has been provided in association with the procedure step to which the fold-out page has been provided. When a button touch is detected, a foldout page may be displayed on the right page MR.

  The procedure manual display unit 34 displays the electronic procedure manual M in the second procedure window as described above. Further, the procedure manual display control unit 32 causes the second procedure window to display that each procedure step has been selected by the operator. When detecting the operator's selection of the procedure step in the second procedure window (when the operator touches the action image M3) in the second procedure window, the procedure manual display unit 34 displays that the procedure step is selected. Is performed by the procedure manual display unit 34. Specifically, when detecting a touch from the operator on the procedure step display area M3A, which is the area where the action image M3 is displayed, the procedure manual display control unit 32 determines the color of the procedure step display area M3A. To change. In the present embodiment, the procedure manual display control unit 32 causes the procedure step display area M3A to display any one of the first color, the second color, the third color, and the fourth color. The procedure manual display control unit 32 switches the color to be displayed each time a touch is detected. The first color indicates an unexecuted state in which the procedure step is not executed. The second color indicates that the procedure step is being executed. The third color indicates an end state in which the procedure step has ended. The fourth color indicates a non-application state in which the procedure step is not applied (not executed) in the current control. First, the procedure manual display control unit 32 displays the first color in the procedure step display area M3A of all the procedure steps. The procedure manual display control unit 32 changes the color while looping the second color, the third color, the fourth color, the first color,... Every time a touch is detected.

  By changing the color of the procedure step display area M3A in this way, for example, the operator confirms that the procedure step in which the third color is displayed has been executed, and the second color is displayed. You can confirm that the procedural step is being executed.

  However, if the procedure manual display control unit 32 displays a notification indicating each state of the procedure step (unexecuted state, execution state, end state, and non-application state) in the procedure step display area M3A, the procedure manual display control unit 32 changes the color. It is not limited to changing. For example, the procedure manual display control unit 32 may cause the procedure step display area M3A to display a character indicating each state name or a different mark assigned to each state. Further, the procedure manual display control unit 32 is not limited to notifying the above four states, but may be any as long as it displays at least an end state. That is, when the selection of the procedure step is detected, the procedure manual display control unit 32 may cause the procedure manual display unit 34 to display that the procedure described in the procedure step has been executed. For example, the procedure manual display control unit 32 sets two types of states on the procedure manual display unit 34: an initial state that has not been touched yet (for example, an unexecuted state), and a state that has been touched (for example, an end state). May be displayed.

  Further, the procedure manual display control unit 32 can specify the operator who performed the touch based on the ID of the operator who performed the touch. The procedure manual display control unit 32 determines the content of the procedure step selected by the touch, the ID of the operator who performed the touch, and the state of the procedure step after the touch (unexecuted state, executed state, end) State and non-application state) are stored in the procedure manual storage unit 30 in association with each other. This makes it possible to confirm which operator or supervisor has changed the state of which procedure step and how.

  Hereinafter, the relationship between the first electronic procedure manual display device 12A and the second electronic procedure manual display device 12B will be described. The first electronic procedure manual display device 12A and the second electronic procedure manual display device 12B display the same electronic procedure manual M. That is, the operator controls the nuclear power plant while watching the display of the electronic procedure manual M on the first electronic procedure manual display device 12A. Then, the supervisor supervises the operation by the operator while watching the display of the same electronic procedure manual M as the display of the first electronic procedure manual display device 12A. The electronic procedure manual M displayed by the first electronic procedure manual display device 12A and the second electronic procedure manual display device 12B are the same, but the displayed page is different depending on the operation of each electronic procedure manual display device 12. There is.

  The first electronic procedure manual display device 12A and the second electronic procedure manual display device 12B only change the color of their own procedure step display area M3A when a touch on one of the procedure step display areas M3A is detected. However, the procedure step display area M3A of the same procedure step in the other electronic procedure manual display device 12 is also changed to the same color. For example, when the worker performs a touch to change the procedure step display area M3A of step S1 of the first electronic procedure manual display device 12A to the second color, the procedure manual display control of the first electronic procedure manual display device 12A is performed. The unit 32 outputs information to that effect to the procedure manual display control unit 32 of the second electronic procedure manual display device 12B. The procedure manual display control unit 32 of the second electronic procedure manual display device 12B changes the area of the procedure step display area M3A of step S1 in the procedure manual display unit 34 of the second electronic procedure manual display unit to the second color based on the information.

  Further, even when there are a plurality of first electronic procedure manual display devices 12A and a plurality of second electronic procedure manual display devices 12B, when a touch on the procedure step display area M3A of any one of the electronic procedure manual display devices 12 is detected, all The area of the procedure step display area M3A of the electronic procedure manual display device 12 is changed to the same color. Since the change in the color of the procedure step display area M3A is reflected on all the electronic procedure manual display devices 12, even when touched by a plurality of operators a plurality of times, the change in color due to the last touch is performed on all the electronic procedure manual display devices M3A. This can be reflected on the electronic procedure manual display device 12.

  Further, when changing the color of the procedure step display area M3A, the procedure manual display control unit 32 displays the ID of the operator who performed the touch in the procedure step display area M3A, for example, in a pop-up or the like. Then, the procedure manual display control unit 32 similarly displays the operator ID in the procedure step display area M3A of the other electronic procedure manual display device 12. Thereby, the operators (operators and supervisors) of all the electronic procedure manual display devices 12 confirm on the spot which operator or supervisor has changed the state of which procedure step and how. It becomes possible.

  In the present embodiment, the first electronic procedure manual display device 12A and the second electronic procedure manual display device 12B have been described as separate independent devices (computers). It may have (two) procedure manual display sections 34. That is, in the present embodiment, the electronic procedure manual display device 12 is configured by a plurality of devices having one procedure manual storage unit 30, one procedure manual display control unit 32, and one procedure manual display unit. Things. However, the electronic procedure manual display device 12 may include one procedure manual storage unit 30, one procedure manual display control unit 32, and a plurality of procedure manual display units 34. In such a case, the procedure manual display control unit 32 controls the display of the plurality of procedure manual display units 34, and the content of the display control is the same as that described above.

  Hereinafter, a control flow of display of the procedure manual display unit 34 by the procedure manual display control unit 32 will be described with reference to a flowchart. FIG. 8 is a flowchart illustrating a control flow of display of the procedure manual display unit by the procedure manual display control unit. As shown in FIG. 8, when the electronic procedure manual display device 12 is started up by the operator, the procedure manual display control unit 32 displays a login screen on the procedure manual display unit 34, and logs in the operator ( Step S10). After detecting the login from the operator, the procedure manual display control unit 32 displays the first procedure window on the procedure manual display unit 34 (step S12), and determines whether the selection of the electronic procedure manual M by the operator is detected. Is determined (step S14). The first procedure window is a screen for allowing the operator to select a desired electronic procedure manual M from the electronic procedure manual M0. When detecting the operator's selection of the electronic procedure manual M (step S14; Yes), the procedure manual display control unit 32 displays the second procedure window on the procedure manual display unit 34, and displays the selected electronic procedure manual M. (Step S15). When the selection of the electronic procedure manual M by the operator is not detected (step S14; No), the procedure manual display control unit 32 returns to step S14 and continues to detect the selection of the electronic procedure manual M by the operator.

  After displaying the electronic procedure manual M in the second procedure window, the procedure manual display control unit 32 determines whether the operator's selection has been detected for the procedure step in the displayed electronic procedure manual M ( Step S16). When a touch operation is performed on the procedure step display area M3A, which is an area where the contents of the procedure steps are described, the procedure manual display control unit 32 determines that the procedure step has been selected by the operator. If the operator's selection is detected (step S16; Yes), the procedure manual stores information of the operator who made the selection, the contents of the selected procedure step, the selected contents, and the date and time when the selection was made. It is stored in the unit 30 (step S17). The information of the selected operator is the ID of the operator. The selection content is information on which color the procedure step display area M3A is to be changed to, that is, which state (unexecuted state, execution state, end state, non-applied state) of the procedure step. If the operator's selection is not detected (Step S16; No), the process returns to Step S16, and the detection of the operator's selection of the procedure step is continued.

  The procedure manual display control unit 32 stores the information of the operator, the content of the selected procedure step, the selected content, and the date and time, and then stores the colors of the procedure step display areas M3A of all the procedure manual display units 34. Is changed (step S18). That is, when there are a plurality of electronic procedure manual display devices 12, when the procedure manual display control unit 32 detects that any one of the electronic procedure manual display devices 12 is selected in the procedure step display area M3A, all the electronic procedure manual display devices are displayed. The same procedure step display area M3A in the device 12 is changed to the same color.

  After changing the color of the procedure step display area M3A of all the procedure manual display sections 34, the process moves to step S19, and when the display processing of the electronic procedure manual M by the operator is completed (step S19; Yes), The display processing ends. If the display process of the electronic procedure manual M by the operator has not been completed (Step S19; No), the process returns to Step S16 and the display process is continued.

  As described above, the electronic procedure manual display device 12 of the nuclear power plant according to the present embodiment includes the procedure manual storage unit 30, the procedure manual display control unit 32, and the procedure manual display unit. The procedure manual storage unit 30 stores the electronic procedure manual M. The electronic procedure manual M is data in which the operation procedure of the nuclear power plant is described for each procedure step. The procedure manual display unit 34 displays the electronic procedure manual M. The procedure manual display control unit 32 controls the display of the electronic procedure manual M, and when the procedure step displayed on the procedure manual display unit 34 is selected by the operator of the electronic procedure manual display device 12, The procedure manual display section 34 displays a message indicating that the procedure step has been selected.

  According to the electronic procedure manual display device 12, the operator can operate the nuclear power plant according to the display of the electronic procedure manual M. At this time, when the operator selects a procedure step on the procedure manual display unit 34, the electronic procedure manual display device 12 displays that the procedure step has been selected. For example, when the execution of a certain procedural step is completed, the operator selects the procedural step on the procedural manual display unit 34. The procedure manual display section 34 displays that the procedure step has been selected, and the operator visually recognizes the display to indicate the progress of the procedure step according to the selection (for example, the procedure step has been completed). Etc.) can be confirmed. As described above, according to the electronic procedure manual display device 12, the operator performs the operation operation of the nuclear power plant according to the display of the electronic procedure manual M, and displays the progress status of the procedure step from the display on the procedure manual display unit 34. Can be confirmed. Therefore, according to the electronic procedure manual display device 12, the operator can suppress an erroneous operation in the operation operation of the nuclear power plant, and can reduce a monitoring burden and a work burden.

  In addition, when the selection of the procedure step is detected as a display indicating that the procedure step is selected, the procedure manual display control unit 32 displays, on the procedure manual display unit 34, the procedure described in the procedure step as already executed. (End state) is displayed. According to the electronic procedure manual display device 12, a display is made to the effect that the procedure described in the procedure step has been executed. Therefore, the operator can suppress the erroneous operation in the operation of the nuclear power plant by checking the display, and can reduce the monitoring burden and the work burden.

  Further, the procedure manual display control unit 32 displays the parameters of the nuclear power plant related to the procedure step in association with the display of the procedure step (action image M3). According to the electronic procedure manual display device 12, the procedure steps can be executed while confirming the parameters related to the procedure steps and the contents of the procedure steps on the same screen. Therefore, the operator can suppress the erroneous operation in the operation of the nuclear power plant by checking the display, and can reduce the monitoring burden and the work burden.

  In addition, the procedure manual display control unit 32 specifies the operator who has selected the procedure step, and stores information of the operator who has selected the procedure step in the procedure manual storage unit 30 in association with the selected procedure step. Let it. According to the electronic procedure manual display device 12, by reading the information in the procedure manual storage unit 30, it is possible to confirm which operator or supervisor has changed the state of which procedure step and how. It becomes. Therefore, according to the electronic procedure manual display device 12, the work history can be confirmed, and the monitoring burden in the operation operation of the nuclear power plant can be reduced.

  The procedure manual display unit 34 is a touch panel having a procedure step display area M3A on which a procedure step is displayed. The procedure manual display control unit 32 performs a touch operation when the procedure step display area M3A is touched by the operator. By changing the color of the displayed procedure step display area M3A, an indication that the procedure step displayed in the procedure step display area M3A has been selected is displayed. According to the electronic procedure manual display device 12, the procedure step can be selected by touching the procedure step display area M3A in which the procedure step is described. Therefore, erroneous selection by the operator can be suppressed. Further, according to the electronic procedure manual display device 12, by changing the color of the procedure step display area M3A in which the procedure steps are described, it is possible to display that the selection has been made. Therefore, the electronic procedure manual display device 12 can suppress erroneous visual recognition of whether or not the operator has been selected. As described above, according to the electronic procedure manual display device 12, it is possible to reduce the monitoring burden in the operation of the nuclear power plant.

  Further, the electronic procedure manual display device 12 according to the present embodiment has a plurality of procedure manual display units 34 for displaying the same electronic procedure manual M. Then, when one of the procedure steps displayed on one of the procedure manual display sections 34 is selected, the procedure manual display control section 32 also notifies other procedure manual display sections 34 that the procedure step has been selected. Is displayed. According to the electronic procedure manual display device 12, even when the electronic procedure manual M displayed on each procedure manual display unit 34 has been read by a plurality of operators or supervisors, all the operators or supervisors However, the fact that the procedural step is selected, that is, the progress of the procedural step can be confirmed on the spot. Therefore, according to the electronic procedure manual display device 12, it is possible to reduce the monitoring load in the operation of the nuclear power plant.

  The states of the procedure steps set in the present embodiment are four types: an unexecuted state, an executed state, an end state, and a non-applied state, and all workers and supervisors change to that state by touching ( Color). However, the procedure manual display control unit 32 restricts the person who can be changed to each state based on the information (ID) of the operator, that is, the change to the predetermined state accepts only selection by the predetermined person. There may be. For example, the person who performs the driving procedure is not the supervisor but the worker. Therefore, the procedure manual display control unit 32 changes to the execution state (change to the second color) or changes to the end state (change to the third color) only when selected (touched) by the operator. ) Is accepted, and even if a selection (touch) is made by the supervisor, a change to the execution state (change to the second color) or a change to the end state (change to the third color) is not performed.

  In this case, an approval state (for example, the fifth color) that can be selected only by the supervisor may be added as the state of the procedure step. For example, when a certain procedure step is completed, the operator selects (touches) the procedure step from the second procedure window of the procedure manual display unit 34 and changes the procedure step to an end state. After confirming that the procedural step has been completed, the supervisor selects (touches) the procedural step that has changed to the ending state, thereby changing the procedural step to the approval state. Thereby, all the workers and the supervisor can recognize that the end of the procedure step has been confirmed (approved) from the supervisor.

(Safety control monitoring system)
Next, the safety system control monitoring system 8 will be described in detail. FIG. 9 is a block diagram showing a connection relationship between the safety-related control and monitoring system and the safety-related system. As described above, the safety system 110 is a system for safely stopping the nuclear power plant when the nuclear power plant is abnormal. The safety-related control and monitoring system 8 monitors and controls the safety-related system 110 when the service-related control system 6 cannot monitor and control the safety-related system 110 due to an accident or the like. The safety system 110 includes a plurality of safety devices 111 having the same function. Each safety device 111 is individually controlled by different systems. As shown in FIG. 9, in the description of the present embodiment, the safety system 110 includes a plurality of safety systems 111 as a first safety system 111A, a second safety system 111B, and a third safety system.

In the parallel parameter image 42A, safety parameter type images 42C indicating the names of the types of the safety-related parameters Pa (parameters Pa1, Pa2, Pa3, Pa4, Pa5, Pa6) are displayed in a row. In addition, adjacent to each safety parameter type image 42C, a safety parameter value image 42D displayed while sequentially updating the value of each safety system parameter Pa is displayed in a row direction for each safety system device 111. . For example, in the example of FIG. 11, the value of the parameter Pa1 of the first safety system device 111A and the value of the parameter Pa1 of the second safety system device 111B are set as the safety parameter value image 42D in the same row as the safety parameter type image 42C called the parameter Pa1. The value, the value of the parameter Pa1 of the third safety device 111C, and the value of the parameter Pa1 of the fourth safety device 111D are displayed.

  As described above, the type of the safety-related parameter Pa is determined in advance. The parallel parameter image 42A displays all safety-related parameters Pa related to CSF (safety function). The parallel parameter display control unit 28 causes the safety-related parameters Pa to be displayed in order from the parameter important for safety of the nuclear power plant in the column direction from top to bottom. Further, the parallel parameter display control unit 28 causes the safety-related parameter display unit 27 to display all of the safety-related parameters Pa on one screen. Note that the parallel parameter display control unit 28 may display only the safety system parameter Pa selected in advance among all the safety system parameters Pa.

  Further, the parallel parameter monitor control unit 28 converts the safety system parameter Pa, which is not a normal value or state, that is, an abnormal value or state, from the safety system parameters Pa displayed as the parallel parameter image 42A into a normal safety system parameter. It is displayed separately from the parameter Pa. In the present embodiment, the parallel parameter monitor control unit 28 highlights the safety parameter value image 42D indicating an abnormal value or state in a color different from a normal one, such as yellow or red.

  The safety function parameter display image 42B is an image displayed above the parallel parameter image 42A. The parallel parameter monitor control unit 28 determines that the safety system parameter Pa affecting each safety function (maintenance of the core cooling, maintenance of the retained water, etc.) displayed in the parallel parameter image 42A as the safety function parameter display image 42B is in an abnormal state. Is displayed, the type of each safety function (maintenance of core cooling, maintenance of retained water, etc.) affected by the abnormal state is displayed in an abnormal / normal state. For example, in the example of FIG. 11, the state of the parameters Pa1 and Pa3 is abnormal, the state of the safety function F1 corresponding to the parameter Pa1 (for example, maintaining core cooling) is NG, and the state of the safety function F3 corresponding to the parameter Pa3 is NG. It indicates that the state of (for example, maintaining the retained water) is Low, which is a state lower than normal.

(Task parameter window)
Next, the task parameter window will be described in detail. The task parameter monitor control unit 29 switches between a first task parameter window and a second task parameter window, which will be described later, as the task parameter windows, and causes the safety-related parameter display unit 27 to display them. FIG. 12 is a diagram illustrating an example of the first task parameter window. When the operator selects the task parameter window, the task parameter monitor control unit 29 causes the safety-related parameter display unit 27 to display the first task parameter window. As shown in FIG. 12, the first task parameter window is a menu screen, and displays a title image 46A, an operation button image 46B, and a menu image 46C. The title image 46A is an image displayed at the top of the screen, and displays the name of the first display (for example, “task parameter menu screen”).

A plurality of emergency procedures are prepared according to the operation contents. In the example of FIG. 12, the plurality of procedure images 46D respectively display an emergency first procedure, an emergency second procedure, and an emergency third procedure.

  FIG. 13 is a diagram illustrating an example of the second task parameter window. The task parameter monitor control unit 29 changes the display from the first task parameter window to the second task parameter window when detecting selection of the procedure image 46D by the operator, that is, touching of the procedure image 46D by the operator. As shown in FIG. 13, the safety-related parameter display unit 27 displays an operation button image 46B, a title image 46G, and a task parameter image 46H on the image display surface in the second task parameter window.

  The title image 46G is an image displayed at the top of the screen, and displays the serial number of the selected emergency procedure and the contents of the emergency procedure. In the example of FIG. 13, the emergency first procedure has been selected, and in the title image 46G, the display of the serial number “emergency first procedure” and the content of the first emergency procedure “reactor trip” are displayed. I have.

  The task parameter image 46H is an image displayed below the title image 46G and almost over the entire screen. The task parameter image 46H displays the safety-related parameters Pa for each procedure step of the emergency operation procedure and for each safety-related device 111. In the example of FIG. 13, the safety parameter Pa is displayed in a table form in the task parameter image 46H. In the task parameter image 46H, a step image 46I, a safety parameter type image 46J, and a safety parameter value image 46K are displayed. The step image 46I is an image in which the procedure steps of the emergency operation procedure are sequentially displayed in the column direction. The safety parameter type image 46J is an image displayed adjacent to the step image 46I. The safety parameter type image 46J displays the type (name) of the safety parameter Pa related to the procedure step displayed in the step image 46I in association with the procedure step of the step image 46I. The safety parameter value image 46K is an image displayed adjacent to the safety parameter type image 46J, and is displayed while sequentially updating the value of each safety system parameter Pa. Note that the safety-related parameters Pa related to the procedural step include various parameters to be controlled in the procedural step, parameters changed by executing the procedural step, and the like.

  In the example of FIG. 13, the procedure steps of the first emergency procedure are steps S1a, S2a, S3a, and S4a. The task parameter display unit 46 displays the steps S1a, S2a, S3a, and S4a in order from the top in the column direction as the step image 46I. Then, the task parameter display unit 46 displays the parameters Pa1, Pa2, Pa3, Pa4, Pa5, and Pa6 as the safety parameter type image 46J. The safety-related parameters Pa related to step S1a are parameters Pa1 and Pa4, the safety-related parameters Pa related to step S2a are parameters Pa2 and Pa3, and the safety-related parameter Pa related to step S3a is a parameter Pa5. The safety-related parameter Pa related to step S4a is a parameter Pa6. The safety-related parameter display unit 27 displays the parameter Pa1 adjacent to the display of step S1a, and displays the parameter Pa4 on the next line. Further, the safety-related parameter display unit 27 displays Step S2a on the next line after the display of the parameter Pa4, and displays the parameter Pa2 adjacent thereto. The safety system parameter display unit 27 displays the safety system parameters Pa related to each procedure step in association with the procedure step by displaying in such an array.

  In the example of FIG. 13, the safety-related parameter display unit 27 displays the value of the parameter Pa1 of the first safety-related device 111A as the safety parameter value image 46K on the same line as the safety parameter type image 46J of the parameter Pa1. The value of the parameter Pa1 of the second safety device 111B, the value of the parameter Pa1 of the third safety device 111C, and the value of the parameter Pa1 of the fourth safety device 111D are displayed while being sequentially updated. The operator visually confirms the second task parameter window and confirms parameters related to the procedure steps to be executed. By operating the button of the operation button image 46B, the operator switches to another procedure step (for example, the next step S5a) and the task parameter image 46H for displaying the related safety parameter Pa.

  The operator switches and displays the above-described parallel parameter window and task parameter window on the safety-related parameter monitoring device 19 as necessary.

(Task window)
Next, the task window will be described in detail. The task control unit 25 switches between a first task window, a second task window, and a third task window, which will be described later, as task windows, and causes the safety-related display unit 21 to display the window. FIG. 14 is a diagram illustrating an example of the first task window. When the operator selects a task window, the task control unit 25 causes the safety-related display unit 21 to display a first task window. As shown in FIG. 14, the first task window is a menu screen, and displays a title image 48A, an operation button image 48B, and a menu image 48C. The title image 48A is an image displayed at the top of the screen, and displays the name of the first task window (for example, “task menu screen”). The operation button image 48B is an image displayed on the side of the screen, and displays various operation buttons. The menu image 48C is an image displayed below the title image 48A and almost over the entire screen, and displays a plurality of procedure images 48D. The procedure image 48D is an image displaying the serial number of the emergency procedure and the content of the emergency procedure. The procedure image 48D is a button display for selecting an emergency procedure on which a serial number or name is displayed. In the example of FIG. 14, the plurality of procedure images 48D display an emergency first procedure, an emergency second procedure, and an emergency third procedure, respectively. Thus, the display contents of the first task window in the example of FIG. 14 are common to the display contents of the first task parameter window in the example of FIG.

  FIG. 15 is a diagram illustrating an example of the second task window. When detecting the operator's selection of the procedure image 48D, that is, the touch operation of the procedure image 48D by the operator, the task control unit 25 changes the display from the first task window to the second task window. The safety device 111 is composed of a plurality of components, and the second task window is a screen for selecting a component that needs to be controlled in the emergency procedure selected in the first task window. As shown in FIG. 15, the safety display unit 21 displays the operation button image 48B, the title image 48G, and the operation target image 48H on the image display surface in the second task window.

  The title image 48G is an image displayed at the top of the screen, and displays the serial number of the selected emergency procedure and the contents of the emergency procedure. In the example of FIG. 15, the emergency first procedure is selected, and in the title image 48G, the letters "emergency first procedure" which is a serial number and the letters "reactor trip" which is the content of the first emergency procedure are displayed. Have been.

  The operation target image 48H is an image displayed below the title image 48G and almost over the entire screen. The operation target image 48H displays, among the components of the safety device 111, the component to be operated, for each procedure step of the emergency procedure. In the example of FIG. 15, a step image 48I and a target device image 48J are displayed in the operation target image 48H. The step image 48I is an image in which the numbers of the procedure steps of the emergency operation procedure are sequentially displayed in the column direction. The target device image 48J is an image displayed adjacent to the step image 48I. The target device image 48J displays the name of the component that requires operation in the procedure step displayed in the step image 48I in association with the procedure step displayed in the step image 48I. The target device image 48J is a button display for starting a component whose name is displayed.

  In the example of FIG. 15, the safety display unit 21 displays the steps S1a and S2a of the procedure steps of the first emergency procedure as the step image 48I. Then, the safety display section 21 displays, as the target device image 48J, components C1, C3, C4, etc., which are components that need to be operated in step S1a, adjacent to the display in step S1a. In the next row of the display in step S1a, a component C5 or the like which is a component that needs to be operated in step S1a is displayed. The safety display unit 21 displays the step S2a as a step image 48I on the line next to the display of the component C5, and adjacent to the display, the components C1 and C2, which are components that need to be operated in the step S2a. C2, component C8, etc. are displayed. By displaying in such an arrangement, the safety display unit 21 displays components that need to be operated in each procedure step in association with the procedure step. By operating the button of the operation button image 48B, the operator switches to another operation step (for example, the next step S3a) and the operation target image 48H for displaying components related thereto.

  FIG. 16 is a diagram illustrating an example of the third task window. When detecting the selection of the target device image 48J by the operator, that is, the touch control operation on the target device image 48J by the operator, the task control unit 25 changes the display from the second task window to the third task window. The third task window is a screen for controlling the component selected in the second task window. As shown in FIG. 16, the safety-related display unit 21 displays an operation button image 48B and a control image 48K on the image display surface in the third task window.

  The control image 48K displays a control button image 48L. The control button image 48L is an image that displays a switch or a controller for controlling the selected component. When detecting the touch operation or the like on the control button image 48L by the operator, the task control unit 25 controls the operation of the selected component based on the operation. For example, when the selected component is an open / close valve and an operation on the control button image 48L to close the valve is input, the task control unit 25 issues a command to close the open / close valve, and issues a command to close the open / close valve. Close.

  As described above, the safety-related control device 17 displays, in the second task window, components that need to be controlled in procedural steps to be executed. On the other hand, the safety-related parameter monitoring device 19 displays the safety-related parameter Pa related to the procedure step to be executed in the second task parameter window. Therefore, when executing the procedural steps, the operator selects the component that needs to be controlled in the second task window while monitoring the related safety parameter Pa in the second task parameter window, and selects the component in the third task window. The operation of the component can be controlled.

(Control processing of task control unit and task parameter monitor control unit)
Next, a control flow of the safety system 110 at the time of an abnormality using the safety control monitoring system 8 described above will be described. The operator controls the operation of the safety system 110 according to an emergency procedure according to the operation content when the nuclear power plant is abnormal, and safely stops the nuclear power plant. In this case, the operator operates the task window displayed by the task control unit 25 while monitoring the safety-related parameters Pa of the safety-related system 110 using the task parameter window displayed by the task parameter monitor control unit 29, and performs the emergency procedure. Execute each procedure step.

  Hereinafter, a control flow of the safety system 110 by the task control unit 25 and the task parameter monitor control unit 29 will be described. FIG. 17 is a flowchart illustrating a control flow of the safety system by the task parameter monitor control unit and the task control unit. When controlling the operation of the safety system 110 when the nuclear power plant is abnormal, the worker selects a task parameter window in the safety system parameter monitoring device 19 and causes the task parameter monitor control unit 29 to display the first task parameter window. . Then, as shown in FIG. 17, the task parameter monitor control unit 29 determines whether the selection (touch operation) of the emergency procedure by the worker is detected in the first task parameter window (Step S20). When the selection of the emergency procedure is detected (step S20; Yes), the task parameter monitor control unit 29 switches the display to the second task parameter window and displays the procedure step of the selected emergency procedure in the second task parameter window. The related safety parameter Pa is displayed (step S22). When the selection of the emergency procedure is not detected (Step S20; No), the task parameter monitor control unit 29 returns to Step S20 and continues the detection of the selection of the emergency procedure.

  After step S22, the operator selects the safety device 111 to be controlled from the plurality of safety devices 111 based on the safety parameter Pa displayed in the second task parameter window. The operator selects a task window in the safety control device 17 that controls the selected safety device 111 and causes the task control unit 25 to display the first task window. The task control unit 25 determines whether or not the selection of the emergency procedure (touch operation) by the worker is detected in the first task window (step S24), and when the selection of the emergency procedure is detected (step S24; Yes). Then, the display is switched to the second task window, and the control component of each procedure step of the selected emergency procedure is displayed in the second task window (step S26). A control component of a procedural step is a component that requires control to execute the procedural step. When the selection of the emergency procedure is not detected (Step S24; No), the task control unit 25 returns to Step S24 and continues the detection of the selection of the emergency procedure.

  After displaying the control component for each procedure step in the second task window, the task control unit 25 determines whether the selection (touch operation) of the control component by the operator is detected (step S28), and the selection of the control component is performed. Is detected (step S28; Yes), the display is switched to the third task window, and the control button image 48L for controlling the selected control component is displayed in the third task window (step S30). When the selection of the control component is not detected (Step S28; No), the task control unit 25 returns to Step S28 and continues to detect the selection of the control component.

  After displaying the control button image 48L, the task control unit 25 determines whether an operation on the control button image 48L by the worker has been detected (step S32), and when an operation on the control button image 48L has been detected. (Step S32; Yes), the operation of the control component is controlled based on the operation on the control button image 48L (Step S34). Thus, the present control ends. If the operation on the control button image 48L is not detected (Step S32; No), the process returns to Step S32, and the operation detection on the control button image 48L is continued.

  The worker controls the safety device 111 by using the task control unit 25 (safety control device 17) and the task parameter monitor control unit 29 (safety parameter monitor device 19) when the nuclear power plant is abnormal. . Further, for example, when the operator wants to monitor all the safety parameters Pa of all the safety devices 111 at once, the operator selects the parallel parameter window in the safety parameter monitor 19 and sends it to the parallel parameter monitor controller 28. A parallel parameter window can be displayed to monitor all safety-related parameters Pa.

  As described above, the safety-related control and monitoring system 8 according to the present embodiment is disposed in the central control room 2 of a nuclear power plant having a plurality of safety-related devices 111. The safety system control monitoring system 8 includes a parallel parameter monitor control unit 28 and a task parameter monitor control unit 29. The parallel parameter monitor control unit 28 displays the safety-related parameters Pa for each type of the safety-related parameters Pa and for each of the plurality of safety-related devices 111. The task parameter monitor control unit 29 displays the safety parameters Pa for each procedure step of the emergency operation procedure and for each of the plurality of safety devices 111.

  According to the safety-related control and monitoring system 8, when the worker controls the safety-related device 111 in accordance with the procedure steps of the emergency operation procedure, the task parameter monitor controller 29 controls the safety-related parameters related to the procedure steps to be executed. Control can be advanced while checking Pa. Further, when the operator needs to control the safety system device 111 in a procedure other than the predetermined emergency operation procedure, or when confirming all the safety system parameters Pa, the parallel parameter monitor controller With 28, the control of the safety system device 111 can be advanced while confirming the important safety system parameter Pa. Therefore, according to the safety system control monitoring system 8, when executing the emergency procedure, the task parameter monitor control unit 29 is operated to perform control other than the emergency operation procedure and to confirm all the safety system parameters Pa. In this case, by operating the parallel parameter monitor control unit 28, the monitoring load can be reduced in both cases.

  Further, the safety-related control and monitoring system 8 includes a safety-related parameter monitoring device 19 and a safety-related control device 17. The safety-related parameter monitoring device 19 includes a task parameter monitor control unit 29 and a safety-related parameter display unit 27. The safety-related control device 17 includes a task control unit 25 that executes operation control of each unit of the safety-related device 111 when performing an emergency operation procedure. The task parameter monitor control unit 29 causes the safety system parameter display unit 27 to display the parameters of the safety system device 111 related to the procedure steps of the emergency operation procedure executed by the task control unit 25 as the safety system parameters Pa. According to the safety-related control monitoring system 8, the safety-related parameter monitoring device 19 displays the safety-related parameters Pa related to the procedural steps to be executed by the safety-related control device 17. Therefore, the safety-related control and monitoring system 8 can reduce the burden of monitoring the safety-related parameters Pa by the operator when the safety-related control device 17 executes the emergency operation procedure.

  In the present embodiment, the safety system control device 17 as one device includes a safety system monitor control unit 22, a safety system operation unit 24, and a task control unit 25. Then, the safety-related control device 17 includes a safety-related monitor window displayed by the safety-related monitor control unit 22, a safety-related operation window displayed by the safety-related operation unit 24, and a task window displayed by the task control unit 25. It is switched and displayed on one screen (safety display section 21).

  Further, in the present embodiment, the safety-related parameter monitoring device 19 as one device includes a parallel parameter monitor control unit 28 and a task parameter monitor control unit 29. Then, the safety-related parameter monitoring device 19 displays a parallel parameter window displayed by the parallel parameter monitor control unit 28 and a task parameter window displayed by the task parameter monitor control unit 29 on one screen (safety parameter display unit 27). Is switched to display.

(Large display device, regular system control device, and supervision auxiliary display device)
Next, the large display device 4, the service control device 10, and the supervision auxiliary display device 15 will be described in detail. As described above, in the large-sized display device 4, the large-sized display panel control unit 4 </ b> B obtains the status, parameters, and the like of each unit of the common-use system 100 from the common-use system 100, and is determined in advance among the acquired parameters and the like. The main parameters Pb are displayed on the large display panel 4A (see FIG. 3). The main parameter Pb is an important parameter for normal operation of the nuclear power plant.

  FIG. 18 is a block diagram illustrating a configuration of the service control device. As shown in FIG. 18, the service control device 10 includes a service control unit 50 and a service control display unit 52. The service control display unit 52 monitors various parameters of the service system 100 and displays a screen for controlling the operation of the service system 100. The regular control display unit 52 is a touch panel, and detects an operation (touch or the like) by an operator (operator). The service control unit 50 controls the operation of the service system 100 based on the operation of the service control display unit 52 by the operator. As described above, the service control device 10 operates and monitors the nuclear power plant during normal times.

  FIG. 19 is a diagram illustrating an example of an image displayed on the large display device, the service control device, and the supervision auxiliary display device. As shown in FIG. 19, the large display panel 4A displays a main parameter image 60 and an abnormal parameter image 62. The main parameter image 60 is an image in which the main parameter Pb is displayed in association with a relative position in the entire nuclear power plant at a location where the main parameter Pb is detected. In the example of FIG. 19, the large display panel 4 </ b> A displays, in the main parameter image 60, a plant schematic image 64, which is a schematic picture of the entire nuclear power plant, and a parameter image 66. The parameter image 66 is an image that displays the types and values of the main parameters Pb. The parameter image 66 is an image displayed in the plant schematic image 64 near the position where the main parameter Pb to be displayed is detected. For example, the main parameter Pb relating to the pressure vessel is displayed near the picture of the pressure vessel in the plant schematic image 64. In this way, the large display panel 4A displays the main parameter Pb in association with the position in the nuclear power plant where the main parameter Pb is detected.

  When any of the main parameters Pb has an abnormal value, the abnormal parameter image 62 displays the type of the abnormal parameter Pc, which is the main parameter Pb that has become abnormal, and the value or state of the abnormal parameter Pc. For example, when the pressure of the pressure vessel becomes an abnormal value, the large display panel 4A displays “pressure vessel pressure” as the type of the abnormal parameter Pc in the abnormal parameter image 62, and displays the value of the abnormal parameter Pc. . If there is a plurality of abnormal parameters Pc, the abnormal parameter image 62 displays the plurality of abnormal parameters Pc in a table.

  As shown in FIG. 19, the regular control display unit 52 of the regular control device 10 displays an initial window which is the same display as the large display panel 4A when not operated by the operator. The main control unit 50 of the main control unit 10 acquires data of an image to be displayed on the large display panel 4A, main parameters Pb, and the like from the large display panel control unit 4B, and causes the main control display unit 52 to display an initial window. The initial window need not be exactly the same as the large display panel 4A as long as it displays the main parameter image 60 and the abnormal parameter image 62 in conjunction with the display of the large display panel 4A.

  As shown in FIG. 19, the supervisory assistant display device 15 outputs image data of a screen displayed on the regular control display unit 52 from the regular control unit 50, and outputs an image displayed on the regular control display unit 52. The same image is displayed. Note that since the same image as the regular control display unit 52 is displayed on the supervision auxiliary display device 15, even when the display of the regular control display unit 52 is switched to a program selection window or the like to be described later, the switched image is displayed. indicate. The supervision assistant display device 15 does not receive an operation by the supervisor, and has only a function of simply displaying an image.

  FIG. 20 is an explanatory diagram illustrating an example of a display image on the regular control display unit. When any of the main parameters Pb has an abnormal value, the regular control unit 50 displays the abnormal parameter image 62 in the initial window. When the selection of the display of the abnormal parameter Pc by the operator, that is, the touch operation on the abnormal parameter image 62 is detected, the regular control unit 50 changes the display from the initial window to the program selection window. The regular control display unit 52 displays a control program of the nuclear power plant related to the selected abnormal parameter Pc in the program selection window. The control program of the nuclear power plant related to the selected abnormal parameter Pc is, for example, a control program for returning the abnormal parameter Pc to a normal value.

  As shown in FIG. 20, the regular control display unit 52 displays a title image 68A, an operation button image 68B, and a program menu image 68C in the program selection window. The title image 68A is an image displayed at the top of the screen, and displays the name of this program selection window (for example, “program selection window”). The operation button image 68B is an image displayed on the side of the screen, and displays various operation buttons. The program menu image 68C is an image that displays a plurality of program selection button images 68D. The program selection button image 68D displays the serial number or name of the corresponding control program. The program selection button image 68D is a button display for starting up a control program on which a serial number or name is displayed. When the control unit 50 detects the selection of the control program by the operator, that is, the touch operation of the program selection button image 68D by the operator, the regular control unit 50 starts up the control program. The operator executes the control program to perform control for returning the abnormal parameter Pc to a normal value.

  When the number of control programs related to the abnormal parameter Pc is one, when the touch operation on the abnormal parameter image 62 is performed on the initial screen, the regular control unit 50 directly displays the program without displaying the program selection window. A control program may be started.

  As described above, the operation monitoring system 1 according to the present embodiment includes the large display panel 4A (display panel) and the service control device 10. The large display panel 4A is disposed at a position visible to all workers in the central control room 2, and displays a main parameter image 60 and an abnormal parameter image 62. The main parameter image 60 is a display in which the main parameters Pb of the nuclear power plant are associated with positions in the nuclear power plant. The abnormal parameter image 62 is a display of an abnormal parameter Pc which is a parameter whose value has become abnormal among the main parameters Pb. The service control device 10 includes a service control unit 50 that controls the operation of the nuclear power plant based on an operation of an operator, and a service control display unit 52 that displays an image under the control of the service control unit 50. The service control unit 50 causes the service control display unit 52 to display an initial window for displaying the main parameter image 60 and the abnormal parameter image 62 in conjunction with the display on the large display panel 4A. When the operator selects the display of the abnormal parameter Pc in the initial window, the service control unit 50 starts up a control program of the nuclear power plant related to the abnormal parameter Pc.

  For example, if the service controller 10 does not display the initial screen, the unskilled operator can determine which control program to start up to return the abnormal parameter Pc to a normal value even if the abnormal parameter Pc occurs. The monitoring burden increases because it takes time to make a judgment. On the other hand, according to the operation monitoring system 1 according to the present embodiment, when the abnormal parameter Pc occurs, simply selecting the display image of the abnormal parameter Pc on the screen of the initial window of the service system controller 10 causes the abnormality. A control program for returning the parameter Pc to a normal value can be started. Therefore, according to the operation monitoring system 1, the monitoring burden on the worker can be reduced.

  Further, the service control unit 50 causes the service control display unit 52 to display a program selection window for displaying a plurality of control programs when an abnormal parameter Pc having a plurality of related control programs is selected in the initial window, When the display of one control program in the program selection window is selected, the selected program is started. According to the operation monitoring system 1, even when there are a plurality of control programs related to the abnormal parameter Pc, the selection can be limited to only the related control programs, so that the monitoring burden on the operator can be further reduced. .

  In addition, the operation monitoring system 1 includes a supervisory control device 14 that is operated by a supervisor who supervises a worker, and a supervisory assistant that is arranged adjacent to the supervisory control device 14 and that displays the same display as the display of the regular system control device 10. And a display device 15. According to the operation monitoring system 1, the same screen as the operation screen of the worker's regular control device 10 can be visually recognized from the supervising place by the supervisory assistant display device 15. Therefore, according to the operation monitoring system 1, the monitoring burden on the supervisor can be reduced.

(2nd Embodiment)
Next, a second embodiment will be described. The operation monitoring system 1 according to the second embodiment differs from the first embodiment in the display on the large display panel 4Aa. In the second embodiment, description of portions having the same configuration as the first embodiment will be omitted.

  FIG. 21 is a diagram illustrating an example of a display on a large display panel according to the second embodiment. As shown in FIG. 21, the large display panel 4Aa according to the second embodiment displays a main parameter image 60a and an abnormal parameter image 62. The large display panel 4Aa displays a trend image 70 in addition to the plant model image 64 and the parameter image 66 in the main parameter image 60a. The trend image 70 is an image displayed corresponding to (adjacent to) the parameter image 66. The trend image 70 displays a change tendency indicating a tendency of the main parameter Pb of the corresponding parameter image 66 to change with time.

  This change tendency is detected by the large display panel control unit 4B. The large display panel control unit 4B obtains the main parameter Pb every time, and compares the obtained value of the main parameter Pb with the value of the previous main parameter Pd which is the main parameter Pb obtained at a timing earlier by the predetermined time T. Then, a change tendency is detected. When the value of the acquired main parameter Pb is higher than the value of the previous main parameter Pd by the first change amount A or more, the large display panel control unit 4B indicates that the value is increasing as the trend image 70. Display climb information. In addition, when the value of the acquired main parameter Pb is lower than the value of the previous main parameter Pd by the second change amount B or more, the large display panel control unit 4B indicates that the value is falling as the trend image 70. Is displayed. The large display panel control unit 4B determines that the value of the acquired main parameter Pb is not larger than the value of the previous main parameter Pd by more than the first change amount A, and that the value of the main parameter Pb is the second main parameter Pb. If the value does not decrease by the change amount B or more, constant information indicating that the value has not changed is displayed as the trend image 70. The large display panel control unit 4B detects the tendency of change each time a new main parameter Pb is acquired, and sequentially switches the ascending display, the descending display, and the constant display.

  As shown in FIG. 21, when displaying the ascending information as the trend image 70, the large display panel 4Aa displays an upward arrow having a tip inclined upward from the horizontal direction as the trend image 70. When displaying the descending information as the trend image 70, the large display panel 4Aa displays a downward arrow having the tip inclined downward from the horizontal direction as the trend image 70. In the case where constant information is displayed as the trend image 70, the large display panel 4Aa displays a horizontal arrow along the horizontal direction as the trend image 70. The large display panel 4Aa changes the inclination of the arrow according to the value. That is, even if the information is ascending, the difference between the value of the previous main parameter Pd and the value of the previous main parameter Pd is large. When the arrow is large, the tip of the downward arrow is inclined downward.

  The large display panel control unit 4B sets the predetermined time T, the first change amount A, and the second change amount B for each main parameter Pb. Therefore, at least one of the predetermined time T, the first change amount A, and the second change amount B has a different value for each main parameter Pb. FIG. 22 is a diagram illustrating the setting of the predetermined time for each parameter. Each graph in FIG. 22 shows an example of a change with time of each of the main parameters Pb. FIG. 22 shows an example in which the main parameters Pb1, Pb2, and Pb3 tend to increase. The value of the main parameter Pb1 does not decrease even in the unit time in the upward trend, and the value increases steadily. The value of the main parameter Pb2 is decreasing even in the unit time, and the value is increasing as a whole while the value repeats decreasing and increasing. The value of the main parameter Pb3 is increasing as a whole while the value repeats a decrease and an increase similarly to the main parameter Pb2, but the fluctuation is not more stable than that of the main parameter Pb2, and the value is largely decreased. There is timing.

  When the fluctuation tendency of the values of the main parameters Pb1, Pb2, and Pb3 is different, the large display panel control unit 4B determines the predetermined time T1 of the main parameter Pb1, the predetermined time T2 of the main parameter Pb2, and the predetermined time T3 of the main parameter Pb3. Are set as mutually different values. For example, the large display panel control unit 4B shortens the predetermined time T1 of the main parameter Pb1 with the smallest change in value per unit time, and sets the predetermined time of the main parameter Pb2 with a larger change in value per unit time. T2 is made longer than the predetermined time T1. In addition, the large display panel control unit 4B sets the predetermined time T3 of the main parameter Pb3 whose fluctuation is not stable to be the longest.

  For example, the large display panel control unit 4B sets the first change amount A and the second change amount B small for the main parameter Pb that requires strict monitoring, and sets the first The change amount A and the second change amount B are set large. Note that the large display panel control unit 4B may set the first change amount A and the second change amount B to the same value for the same main parameter Pb.

  In addition, the large display panel control unit 4B acquires the information of the allowable upper limit value, the allowable lower limit value, and the allowable median value of the main parameter Pb, and based on these, obtains the rising information as the first rising information and the second rising information. And the descending information may be distinguished and displayed as the first descending information and the second descending information. The allowable upper limit value is a value set in advance for each main parameter Pb. When the value of the main parameter Pb becomes larger than the allowable upper limit value, it is determined that the value is not normal and is displayed as an abnormal parameter Pc. The permissible lower limit is a value set in advance for each main parameter Pb. If the value of the main parameter Pb is smaller than the permissible lower limit, the value is determined to be abnormal and is displayed as an abnormal parameter Pc. The allowable median value is a median value between the allowable upper limit value and the allowable lower limit value.

  FIG. 23 is a graph for explaining the ascending information and the descending information. FIG. 23 is a graph showing an example of the fluctuation of the main parameter Pb with time. The large display panel control unit 4B displays a large display in the area L1 where the main parameter Pb is in a rising trend, that is, when the rising information is displayed, and the value is between the allowable lower limit value and the allowable median value. The first rising information is displayed on the board 4Aa. The large display panel control unit 4B displays a large display in the area L2 where the main parameter Pb is in the upward trend, that is, when the upward information is displayed, and the value is between the allowable median value and the allowable upper limit value. The second rising information is displayed on the board 4Aa.

  In addition, the large display panel control unit 4B determines that the main parameter Pb is in a downward trend, that is, in a case where the descending information is displayed, and in a region L3 where the value is between the allowable median value and the allowable upper limit value, The first descending information is displayed on the large display panel 4Aa. The large display panel control unit 4B performs a large display in an area L4 in which the main parameter Pb is in a downward trend, that is, in the case of displaying the downward information, and the value is between the allowable lower limit value and the allowable median value. The second descent information is displayed on the board 4Aa.

  The first ascending information and the second ascending information are upward arrows having the same inclination as long as the amounts of change are the same, but are displayed differently by, for example, different colors to be displayed. Similarly, the first descending information and the second descending information are downward arrows having the same inclination if the amounts of change are the same. For example, the display may be different from each other by using different colors for display. I have. If the main parameter Pb is the second rising information, the possibility that the main parameter Pb will exceed the allowable upper limit if the rising trend continues as it is becomes higher than that of the first rising information. In the case where the main parameter Pb is the second descending information, if the descending trend continues as it is, the possibility that the main parameter Pb falls below the allowable lower limit becomes higher than that in the case of the first descending information. Therefore, the large display panel control unit 4B displays the second ascending information and the second descending information in, for example, yellow, thereby facilitating the attention of the operator.

  As described above, the operation monitoring system 1 according to the second embodiment includes the large display panel 4Aa (display panel) and the large display panel control unit 4B that controls the display of the large display panel 4Aa. The large display panel control unit 4B detects a change tendency indicating a tendency of the main parameter Pb to change with time, and causes the large display panel 4Aa to display the change tendency in association with the main parameter Pb.

  If the change tendency is not displayed on the large display panel, the operator needs to integrate the values of the main parameters Pb at each time point and calculate the change tendency by himself. On the other hand, according to the operation monitoring system 1, the operator can visually recognize the tendency of the change with time at a glance only by visually recognizing the large display panel 4Aa. Therefore, according to the operation monitoring system 1, it is not necessary to calculate the change tendency, and the monitoring burden on the worker can be reduced.

  In addition, when the main parameter Pb has increased by the first change amount A or more than the predetermined time T before, the large display panel control unit 4B displays the increase information indicating that the value has increased, and displays the main parameter Pb. If Pb has decreased by the second variation amount B or more before the predetermined time T, descending information indicating that the value has decreased is displayed. According to the operation monitoring system 1, it is possible to check at a glance whether the value is increasing or decreasing, so that the monitoring burden on the operator can be further reduced.

  In addition, the large display panel control unit 4B sets at least one of the predetermined time T, the first change amount A, and the second change amount B for each main parameter Pb. Thus, the large display panel control unit 4B can appropriately set the change tendency for each type of the main parameter Pb. Therefore, according to the operation monitoring system 1, a more appropriately set change tendency can be visually recognized, so that the monitoring burden on the operator can be further reduced.

  In addition, the large display panel control unit 4B acquires information on the allowable upper limit value, the allowable lower limit value, and the allowable median value of the main parameter Pb. The large display panel control unit 4B displays the first rising information when the main parameter Pb is between the allowable lower limit value and the allowable median value when displaying the rising information, and the main parameter Pb is displayed. When it is between the allowable median value and the allowable upper limit value, the second rising information is displayed. The large display panel control unit 4B displays the first descending information when the main parameter Pb is between the permissible median value and the permissible upper limit value when the main parameter Pb is between the permissible median value and the permissible upper limit value. If it is between the allowable lower limit value and the allowable median value, the second rise information is displayed. In the case of the second rising information and the second falling information, the possibility of being outside the range of the allowable upper limit value and the allowable lower limit value is higher than in the case of the first rising information and the first falling information. Therefore, according to the operation monitoring system 1, by displaying these differently, the operator's attention can be easily drawn, and the monitoring load on the operator can be further reduced.

  The embodiment of the present invention has been described above, but the embodiment is not limited by the contents of this embodiment. The above-mentioned components include those that can be easily assumed by those skilled in the art, those that are substantially the same, and those that are in the so-called equivalent range. Further, the components described above can be appropriately combined. Furthermore, various omissions, substitutions, or changes of the components can be made without departing from the spirit of the above-described embodiment.
