(Embodiment 1)
FIG. 1 is a block diagram schematically showing a configuration of a plant operation support apparatus 10 according to the present embodiment. The plant operation support device 10 is a device that supports plant operation by grasping the state of the plant and displaying plant information necessary for operating each device constituting the plant. As shown in FIG. 1, the plant operation support apparatus 10 includes a causal relationship information storage unit (comprising a hard disk or memory) 12 and an input unit 13 (mouse, keyboard, touch panel, etc.) operated by a plant operator. A confirmation target device extraction unit (consisting of a CPU or the like) 16, an information extraction unit 17 (consisting of a CPU or the like), an information processing unit 18 (consisting of a CPU or the like), and a display unit (display). 20), a plant state storage unit (comprising a hard disk or memory) 22 and a line drawing information storage unit (comprising a hard disk or memory) 23. 1 can be realized by mounting a program programmed with the following operations or functions in a computer system such as a microcomputer and operating the program.

The input unit 13 inputs various events to be executed in the plant. Then, the causal relationship information storage unit 12 indicates the relationship between the event change of the plant accompanying the event input from the input unit 13 and another event change automatically caused in association with the event change of the plant. It is stored and retained as causal information in the form of “cause and result”. Here, “causal relationship information” means (a) device operation (cause) and state change (result) of other devices accompanying or interlocking with it, or (b) when the cause includes an operation condition. The data is expressed as a change in the state of the device that occurs in accordance with the satisfaction of the operation condition. For example, in the case of (a) above, the format of the look-up table results from the fact that “valve A is closed and valve B changes from the closed state to the open state” due to “valve A is closed”. And remembered and saved. Also, for example, in the case of (b) above, when an alarm indicating an abnormal state occurs in the plant, “confirm that valve A and valve B are closed according to the alarm information (cause). (Result) "is stored and saved.

Further, the plant state storage unit 22 stores and saves the state of the plant transmitted from the plant to the apparatus as electronic data.

In addition, the line drawing information storage unit 23 displays drawing data for displaying parts representing the plant equipment on the screen of the display unit 20 on the monitor screen or operation screen displayed on the screen of the display unit 20 for each part. Memorize and save.

Next, the operation of the plant operation support apparatus 10 in FIG. 1 will be described.

First, the input unit 13 instructs the operation start of various events to be executed in the plant displayed on the screen of the display unit 20 by an operation by the operator of the plant. As such an event, for example, an instruction “the operation target device is a valve A and this valve A is closed” is input to the apparatus 10, and the instruction is received via the apparatus 10. Let the plant perform the operation.

The confirmation target device extraction unit 16 accesses the causal relationship information storage unit 12 to extract the causal relationship information caused by the operation procedure of the operation target device, and corresponds to the extracted result of the causal relationship. In the step, a device to be confirmed that requires state confirmation is automatically extracted. In other words, the confirmation target device extraction unit 16 extracts a confirmation target device that inevitably undergoes a next event change based on the extracted causal relationship information. For example, in the example of FIG. 9, the causal relationship (close valve A) caused by the (N + 1) -th operation procedure (valve A is closed) in the causal relationship information (valve B is “open”). It is determined that the operation target device is the valve B based on the causal information.

Thereafter, the information extraction unit 17 extracts the current state (state before change) of the confirmation target device extracted by the confirmation target device extraction unit 16 from the plant state storage unit. For example, in the example of FIG. 9, the information extraction unit 17 detects the “closed” state of the valve B.

Then, the information processing unit 18 processes the data indicating the current state of the device to be confirmed extracted by the information extraction unit 17 into data in an expression format that is easy for the plant operator to identify. That is, the information processing unit 18 displays the extracted data indicating the current state of the confirmation target device and the confirmation target device (corresponding to one part in the plant system diagram) on the screen of the display unit 20. The device to be confirmed is confirmed based on the line drawing information (the drawing data of the corresponding part read by the information processing unit 18 accessing the line drawing information storage unit 23) for expression in the plant system diagram. Data that visually represents the current state is created so that the operator can easily identify (identify) the data. In addition, the information processing unit 18 further corresponds to the result of the causal relationship information that the device to be confirmed corresponds to the cause of the causal relationship information with respect to the image data created by the unit 18. In order to make it easier for the operator to identify that the current state has changed to the state of the result of the causal relationship information in accordance with the timing at which the state has been changed (the information indicating the timing is received from the plant). The data expressed as a model is generated again.

Next, the generated data for the confirmation target device is output to the display unit 20. As a result, the display unit 20 displays the data about the confirmation target devices (data before and after the event change of the confirmation target device) sequentially output from the display screen data output unit 19 together with the monitoring screen or operation screen data.

According to the configuration and the operation of the apparatus 10 described above, based on the causal relationship information indicating the causal relationship, whether or not the state of the device to be confirmed has been changed at a correct timing or when there is an operation condition The operator of the plant can visually check whether or not the state of the confirmation target device has been changed at the correct timing after the operation target device has been operated while satisfying the operation condition. In addition, the plant operator can grasp the abnormal state change in advance. For this reason, the adoption of the present apparatus 10 provides the advantage that accidents can be prevented and the safety of plant operation can be further enhanced. Furthermore, only symbols representing the device to be confirmed, which is the minimum necessary information for the plant operator, and their states are displayed in the empty space of the screen information indicating the plant system diagram. This eliminates the need for redisplaying hidden information, searching for equipment when displaying the entire screen, and moving the flow lines on multiple screens, which can save labor for plant operators. There is also an advantage.

(Embodiment 2)
FIG. 10 is a block diagram schematically showing the configuration of the plant operation support apparatus 10 according to the present embodiment. The plant operation support device 10 is a device that supports plant operation by grasping the state of the plant and displaying plant information necessary for operating each device constituting the plant.

As shown in FIG. 10, the plant operation support apparatus 10 includes an operation procedure data storage unit (comprising a hard disk or memory) 11, a causal relationship information storage unit (comprising a hard disk or memory) 12, and the plant. An input unit 13 (comprising a mouse, a keyboard, a touch panel, etc.) operated by an operator, an operation information extracting unit (comprising a CPU, a memory, etc.) 14 and an operation step determining unit (comprising a CPU, etc.) 15 A confirmation target device extraction unit (consisting of a CPU or the like) 16, an information extraction unit 17 (consisting of a CPU or the like), an information processing unit 18 (consisting of a CPU or the like), and a display screen data output unit (CPU). 19), a display unit (comprising a display device, etc.) 20, and an operation history data storage unit (comprising a hard disk or memory). 1, the plant state storage part (consisting of hard disk, memory, or the like.) 22, line drawing information storage unit (consisting of hard disk, memory, or the like.) 23, a. Each component 11 to 23 in FIG. 10 can be realized by mounting a program programmed with the following operations or functions in a computer system such as a microcomputer and operating the program.

In FIG. 10, the operation procedure data storage unit 11 stores and holds electronic data indicating each of a plurality of procedure manuals (see FIG. 9) created corresponding to each operation of the plant. Here, as shown in FIG. 9, the electronic data of each procedure manual includes electronic data indicating each operation procedure to be sequentially executed in the procedure manual.

Further, the operation history data storage unit 21 stores and saves all procedures operated retroactively from the present as electronic data together with operation times of the respective procedures.

Next, the operation of the plant operation support apparatus 10 in FIG. 10 will be described.

First, the input unit 13 instructs the operation start of various events to be executed in the plant displayed on the screen of the display unit 20 by an operation by the operator of the plant. As such an event, for example, an instruction “the operation target device is a valve A and this valve A is closed” is input to the apparatus 10, and the instruction is received via the apparatus 10. Let the plant perform the operation.

Therefore, the operation information extraction unit 14 selects information related to selection of the operation target device (for example, the valve A which is the operation target device) or information related to device operation (valve A from the various events input from the input unit 13. Is closed, and the extracted data is stored and retained. The operation information extraction unit 14 outputs the extracted data related to the operation target device to the information processing unit 18 described later, and the information processing unit 18 holds the received data related to the operation target device.

Next, the operation step determination unit 15 accesses the operation history data storage unit 21 and refers to the past history data one by one based on the extracted data received from the operation information extraction unit 14. Thus, it is estimated which procedure manual including the operation currently being executed in the plant, that is, which procedure manual is currently used. With this estimation function, the operation step determination unit 15 recognizes which is the procedure manual including the current execution step. Alternatively, in order to further ensure the estimation of the corresponding procedure manual, the operation step determination unit 15 further accesses the plant state storage unit 22 and based on the data extracted by the operation information extraction unit 14, the current plant By confirming a series of past plant states including the state, a procedure manual including the current execution step is estimated. After estimating the corresponding procedure manual, the operation step determination unit 15 accesses the operation procedure data storage unit 11 and reads the estimated data of the corresponding procedure manual (procedure manual data). Thereafter, the operation step determination unit 15 determines whether the current execution step or the current execution procedure is one of the procedures in the procedure manual data based on the series of procedures indicated by the read procedure manual data and the current plant state. Estimate. For example, the procedure manual (1) shown in FIG. 9 is estimated, and the procedure N in the procedure manual (1) is estimated to be the current execution step. Based on the estimation result, the operation step determination unit 15 determines the procedure indicating the operation target device corresponding to the cause of certain causal relationship information and the operation of the operation target device, following the estimated current execution step. It is estimated that For example, as shown in FIG. 9, it is estimated that the (N + 1) -th procedure, which is the next step, is a procedure indicating the operation content of the operation target device. Then, the operation step determination unit 15 outputs the content of the estimated operation procedure of the operation target device (for example, in FIG. 9, the valve A is closed) to the confirmation target device extraction unit 16.

The plant automatically operates the operation target device under the control of the software for the plant and the result of the causal relationship caused by the operation in accordance with the command of the event from the input unit 13. Perform the appropriate operation step.

The confirmation target device extraction unit 16 accesses the causal relationship information storage unit 12 after receiving the operation procedure information of the operation target device estimated by the operation step determination unit 15, and causes the operation procedure of the operation target device. The causal relationship information is extracted, and the verification target device that requires the status confirmation in the next step corresponding to the extracted result of the causal relationship is automatically extracted. That is, the confirmation target device extraction unit 16 (a) based on the extracted causal relationship information, (a) a confirmation target that is inevitably caused next by execution of the operation of the operation target device estimated by the operation step determination unit 15 In the case where the operation procedure of the operation target device estimated by the operation step determination unit 15 is accompanied by confirmation of the operation condition, the device is extracted after confirming that the operation condition is satisfied. Extract the devices to be checked. For example, in the example of FIG. 9, since the (N + 1) th operation procedure (valve A is closed) is estimated as the operation procedure of the operation target device, the (N + 1) th operation procedure is included in the causal relationship information. The causal relationship (valve A is closed. ⇒ Confirm that valve B is “open”) caused by the operation procedure (valve A is closed) is extracted, and the operation is performed based on the causal relationship information. It is determined that the target device is the valve B.

Thereafter, the information extraction unit 17 detects the current state (the state before the change) of the confirmation target device extracted by the confirmation target device extraction unit 16 from the procedure manual. For example, in the example of FIG. 9, the information extraction unit 17 confirms the Nth procedure in the procedure manual (1) and detects the “closed” state of the valve B.

Then, the information processing unit 18 processes the data indicating the current state of the confirmation target device extracted by the information extraction unit 17 into data (first electronic data) in an expression format that is easy for the plant operator to identify. To do. That is, the information processing unit 18 displays the extracted data indicating the current state of the confirmation target device and the confirmation target device (corresponding to one part in the plant system diagram) on the screen of the display unit 20. The device to be confirmed is confirmed based on the line drawing information (the drawing data of the corresponding part read by the information processing unit 18 accessing the line drawing information storage unit 23) for expression in the plant system diagram. Data that visually represents the current state so as to be easily identified by the operator is created. In addition, based on the extracted data received from the operation information extraction unit 14 and the line drawing information, the current state of the operation to be operated is similarly visually expressed so that the operator can easily identify (second electronic data). ). In addition, the information processing unit 18 further corresponds to the result of the causal relationship information that the device to be confirmed corresponds to the cause of the causal relationship information with respect to the image data created by the unit 18. In order to make it easier for the operator to identify that the current state has changed to the state of the result of the causal relationship information in accordance with the timing at which the state has been changed (the information indicating the timing is received from the plant). The data (first reproduction electronic data) expressed in a realistic manner is generated again.

Next, the display screen data output unit 19 converts each data generated by the information processing unit 18 into the plant system in the monitoring drawing (for example, 20D in FIG. 2 described later) displayed on the screen of the display unit 20. In the data of the figure (for example, SF of FIG. 2 described later), the image data that can be displayed so as not to overlap with the image data of each component other than the confirmation target device is generated, and the generated image data of the confirmation target device is generated. Output to the display unit 20. As a result, the display unit 20 displays the generated image data (the current state of the confirmation target device) of the confirmation target devices sequentially output from the display screen data output unit 19 together with the image data of the monitoring drawing on the screen. Display of image data to be displayed ⇒ Display of image data indicating the state of the device to be confirmed after the confirmed state change is displayed.

According to the configuration and operation of the apparatus 10 according to the present embodiment described above, whether or not the state of the device to be confirmed has been changed at the correct timing based on the causal relationship information indicating the causal relationship, or the operation If there is a condition, the plant operator visually confirms whether or not the operation target device has been operated while satisfying the operation condition and whether or not the confirmation target device has changed its state at the correct timing. I can do it. In addition, the plant operator can grasp the abnormal state change in advance. For this reason, the adoption of the present apparatus 10 provides the advantage that accidents can be prevented and the safety of plant operation can be further enhanced. Furthermore, only symbols representing the device to be confirmed, which is the minimum necessary information for the plant operator, and their states are displayed in the empty space of the screen information indicating the plant system diagram. This eliminates the need for redisplaying hidden information, searching for equipment when displaying the entire screen, and moving the flow lines on multiple screens, which can save labor for plant operators. There is also an advantage.

Hereinafter, the contents of the present embodiment will be described as the third to ninth embodiments.

(Embodiment 3)
FIG. 2, which is an example of the present embodiment, is a diagram schematically illustrating an example of a method for displaying the confirmation target device when the deformation of the system diagram is not necessary. Here, “deformation” refers to an operation of deforming a drawing by performing processing such as reduction or parallel movement on a single symbol or a plurality of symbols.

In FIG. 2, the operation target device A001 (indicated by an arrow in FIG. 2) described in the lower left in the system diagram SF of the monitoring drawing 20D shown on the screen of the display unit 20 of FIG. The state change of the confirmation target device B001 before and after the operation of the operation target device) is shown in a visual expression that is easy for the operator to identify. Below, each step in the identification display of the state change of confirmation object apparatus B001 is described.

(1) in FIG. 2: The operation information extraction unit 14 in FIG. 10 extracts input information from the input unit 13 and selects an operation target device (in this example, a valve A001). Then, the operation step determination unit 15 in FIG. 10 estimates the procedure manual i (i = 1, 2,...) At the time of operation, and then adds the operation performed so far and the procedure manual i at the time of operation. By comparing with the described procedure, the current work step in the operating procedure manual i is determined. In this example of FIG. 2, it is determined that [Procedure N] “Close valve A001” is an operation currently in progress in the plant.

(2) in FIG. 2: [Procedure N + 1] “Procedure that valve B001 changes from“ Closed ”to“ Open ””, which is the next step of [Procedure N], is the procedure accompanying the operation of [Procedure N]. Therefore, [Procedure N] and [Procedure N + 1] are procedures corresponding to the cause and result of the causal relationship information, respectively, so that the units 16, 17, 18, and 19 in FIG. Prior to the operation, the current state (“closed” state) of the confirmation target device B001 is extracted as the pre-operation state, and the pre-operation state is represented by a symbol. In this example of FIG. 2, the confirmation target device B001 is in a “closed” state in an empty space on the upper right side in the system diagram SF (portion surrounded by a thick circle C1 in FIG. 2 (2)). It is displayed.

(3) in FIG. 2: The plant changes the operation target device (valve A001) from the “open” state to the “closed” state in accordance with [Procedure N]. Accordingly, the plant automatically shifts to a work step for changing the confirmation target device (valve B001) from the “closed” state to the “open” state.

(4) in FIG. 2: The information extraction unit 17, the information processing unit 18, and the display screen data output unit 19 in FIG. 10 set the state of the operation target device (valve A001) displayed in the system diagram SF to “closed”. On the other hand, the state of the confirmation target device (valve B001) partially displayed in the empty space in the system diagram SF is automatically updated according to the timing of the state change of the confirmation target device (valve B001). Then, “open” is displayed again (the portion surrounded by the thick circle C2 in FIG. 2 (4) is the empty space).

In addition, when the confirmation target device exists in the same screen, it is possible to highlight the change in state of the confirmation target device (valve B001) by changing the color of the confirmation target device. This function is executed by the deforming unit 19D in FIG.

According to the present embodiment, since the device state before and after the operation can be displayed for the device whose device state is automatically changed according to the operation on the specific device, the timing of the device state change and the device operation There is an advantage that the operator can visually confirm the validity.

The state change of the confirmation target device B001 before and after the operation of the operation target device is a visual expression that is easy for the operator to identify, and a region near the expression of the operation target device A001. Shown in Below, each step in the identification display of the state change of confirmation object apparatus B001 is described.

(1) in FIG. 3: The operation information extraction unit 14 in FIG. 10 extracts the input information from the input unit 13 and selects the operation target device (the valve A001 in this example in FIG. 3). Then, the operation step determination unit 15 in FIG. 1 estimates the operation procedure i (i = 1, 2,...) At the time of operation, and then adds the operation performed so far and the operation procedure i at the time of operation. By comparing with the described procedure, the current work step in the operating procedure manual i is determined. In this example of FIG. 3, it is determined that [Procedure N] “Close valve A001” is an operation currently in progress in the plant.

(2) in FIG. 3: The confirmation target device extraction unit 16 in FIG. 10 confirms that [procedure N + 1] “valve B001 is changed from“ closed ”to“ open ”, which is the next step of [procedure N]. It is determined that it is a procedure accompanying the operation of [Procedure N], that is, [Procedure N] and [Procedure N + 1] are procedures corresponding to the cause and result of causal relationship information, respectively. Therefore, each of the units 16, 17, 18, and 19 in FIG. 10 extracts the current state (“closed” state) of the confirmation target device B001 as the pre-operation state prior to the operation of the operation target device A001, and the pre-operation state is extracted. Expressed with symbols. However, as shown in (1) of FIG. 3, since there is not a sufficient display area in the system diagram SF of the display destination, the display area of the confirmation target device B001 is generated by deforming the system diagram SF. There is a need. Here, the display area of the confirmation target device B001 is generated so that the operation target device A001 and the confirmation target device B001 are arranged close to each other. In the present example of FIG. 3, in the system diagram SF, the confirmation target device (valve B001) is an upper region of the operation target device (valve A001) (a region surrounded by a thick circle C3 in (2) of FIG. 3). 1), the deforming unit 19D in FIG. 1 deforms a plurality of symbol groups existing in the area surrounded by the thick circle C4 in (2) of FIG. The result of the deformation is as shown in (3) of FIG.

(3) in FIG. 3: The plant changes the operation target device (valve A001) from the “open” state to the “closed” state in accordance with [Procedure N]. Accordingly, the plant automatically shifts to a work step for changing the confirmation target device (valve B001) from the “closed” state to the “open” state.

FIG. 3 (4): The information extraction unit 17, the information processing unit 18 and the display screen data output unit 19 in FIG. 10 set the state of the operation target device (valve A001) displayed in the system diagram SF to “closed”. On the other hand, the state of the confirmation target device (valve B001) is automatically displayed again in “open” according to the timing of the state change of the confirmation target device (valve B001) ((4 in FIG. 3). ) A portion surrounded by a thick circle C5 is a redisplay area of the valve B001.)

In addition, when the confirmation target device exists in the same screen, it is possible to highlight the change in state of the confirmation target device (valve B001) by changing the color of the confirmation target device. This function is executed by the deforming unit 19D in FIG.

According to the present embodiment, the state of the confirmation target device whose device state is automatically changed in accordance with an operation on a specific device can be displayed in the vicinity area of the operation target device by deformation. The operator of the plant can visually confirm the timing of the state change and the validity of the equipment operation.

(Embodiment 5)
FIG. 4, which is an example of the present embodiment, schematically shows an example of the operation conditions of the operation target device (valve A001 in this example) and the display method example of the confirmation target device when the deformation of the system diagram is unnecessary. FIG.

First, the operation step determination unit 15 determines the current work step in the estimated operation procedure manual by comparing the history of the execution procedure so far, the operation procedure manual and the electronic data such as the current plant state. To do. Then, when the “operation condition” is included in the determined work step or the procedure N of the procedure manual i, the operation step determination unit 15 confirms the device to be determined and the confirmation target indicated in the operation condition. 10, the information processing unit 18 in FIG. 10 combines the line drawing information representing the symbol of the determination target device and the current value of the parameter to be confirmed, and displays an image of these information in FIG. The information is displayed in an empty space in the system diagram SF in the screen of the display unit 20 (see (1) in FIG. 4). In this embodiment, since a case where there is a sufficient free space for display is handled, the deformation of the system diagram SF is not necessary.

When the support device receives confirmation information from the plant that satisfies the “operation condition” indicated in the work step in the current work step of the operation target device, each unit 16 in FIG. 17, 18, and 19 display a dialog DF for operating the operation target device (valve A001) (refer to the display in the area surrounded by the thick circle C7 in FIG. 4 (2)). The current state of the confirmation target device (valve B001) whose state is changed in accordance with the operation of the operation target device (valve A001) (set to the “closed” state) is displayed in the empty space in the system diagram SF. (Refer to (3) in FIG. 4). The subsequent steps are the same as the procedure after (3) described in the second embodiment.

On the other hand, when the operation condition is not satisfied, the word “unsatisfied operation condition” indicating that the operation is not possible is displayed in an empty space in the system diagram SF (refer to the left side of (2) in FIG. 4). The support device cannot proceed to the subsequent steps.

In addition, when the confirmation target device exists in the same screen, it is possible to highlight the change in state of the confirmation target device (valve B001) by changing the color of the confirmation target device. This function is executed by the deforming unit 19D in FIG.

According to the present embodiment, it is possible to display the device status before and after the operation for the operation condition of the specific device and the confirmation target device whose device state is automatically changed with the operation of the specific device. Therefore, the operator of the plant can easily determine the operation start timing and the state change timing of the device to be confirmed, and the advantage that the validity of the device operation can be visually confirmed can be obtained.

FIG. 5, which is an example of the present embodiment, schematically illustrates an example of a display method of the operation condition of the operation target device (valve A001 in this example) and the confirmation target device when the deformation of the system diagram is necessary. FIG.

First, the operation step determination unit 15 determines the current work step in the estimated operation procedure manual by comparing the history of the execution procedure so far, the operation procedure manual and the electronic data such as the current plant state. To do. Then, when the “operation condition” is included in the determined work step or the procedure N of the procedure manual i, the operation step determination unit 15 confirms the device to be determined and the confirmation target indicated in the operation condition. 10, the information processing unit 18 in FIG. 10 combines the line drawing information representing the symbol of the determination target device and the current value of the parameter to be confirmed, and displays an image of these information in FIG. The information is displayed in an empty space in the system diagram SF in the monitoring screen 20D of the display unit 20. However, in the present embodiment, unlike the case of the fourth embodiment, there is not enough free space for display in the system diagram SF of the display destination, so the deformed portion 19D in FIG. It is necessary to create an empty space in the system diagram SF by deforming the diagram SF. At that time, the deforming unit 19D in FIG. 10 displays the information image display area so that the operation target device (valve A001) and the confirmation target device (valve B001 in this example) are arranged close to each other. (See (1) in FIG. 4).

When the operation step determination unit 15 in FIG. 10 confirms that the operation condition in the procedure N of the procedure manual i is satisfied, the units 18 and 19 in FIG. 10 operate the operation target device (valve A001). The dialog DF is displayed in an empty space in the system diagram SF (displayed in a region surrounded by a thick circle C9 in the right diagram of (2) in FIG. 5) and the operation target device. The current state before the operation of the confirmation target device (valve B001) whose state is automatically changed in accordance with the operation of (valve A001) continues to be in the empty space near the operation target device (valve A001). It is displayed (see (3) in FIG. 5). The subsequent steps are the same as the procedures after (3) of the third embodiment.

On the other hand, when the operating condition is not satisfied, the word “unsatisfied operating condition” indicating that the operation is not possible is displayed in the empty space in the deformed system diagram SF (see the left side of FIG. 5 (2)). Refer to this), and this support device cannot proceed to the subsequent steps.

In addition, when the confirmation target device exists in the same screen, it is possible to highlight the change in state of the confirmation target device (valve B001) by changing the color of the confirmation target device. This function is executed by the deforming unit 19D in FIG.

According to the present embodiment, the operation target device in the monitoring screen of the display unit for the operation condition of the specific device and the confirmation target device whose device state is automatically changed in accordance with the operation of the specific device. Since the status of the device to be checked before and after the operation of the operation target device can be displayed near the display position, the movement of the flow line can be reduced, and the operation start timing and the state change timing Can be easily discriminated by the plant operator, and the validity of the equipment operation can be visually confirmed.

(Embodiment 7)
FIG. 6, which is an example of the present embodiment, is a confirmation when the equipment state of the plant is automatically changed with the occurrence of an alarm indicating an abnormality in the plant state (corresponding to the cause of causal relationship information) as a trigger. It is a figure which shows the example of a display method of object apparatus AA.

Since it is difficult to predict the timing at which an alarm is generated, it is difficult to display the state of the confirmation target device AA before the alarm is generated in advance.

Therefore, whether or not the state of the confirmation target device AA (corresponding to the result in the causal relationship information) indicated in the procedure manual i estimated from the causal relationship information has been changed as instructed in the procedure N after the occurrence of the alarm. This is determined by the information extraction unit 17 in FIG. 10, and the units 18 and 19 in FIG. 10 display the determination result (second electronic data) on the monitoring screen 20 </ b> D of the display unit 20.

As an example of the display method, the information extraction unit 17 in FIG. 10 detects that the state of each confirmation target device AA has changed after the alarm is generated, that is, the state of each confirmation target device AA has changed at the correct timing. In this case, in order to show the operator that the state of each confirmation target device AA has been correctly changed in an easy-to-identify expression format, a black circle mark is shown in the thick circle C10 in FIG. ● is displayed in the vicinity of the confirmation target device AA, but otherwise, that is, for the confirmation target device AA whose state has already been changed before the occurrence of the alarm, the confirmation target device AA In order to show the current state to the operator in an easy-to-identify expression format, a circle mark hatched with a diagonal line is displayed in the vicinity of the confirmation target device AA. In this manner, the determination information (second electronic data) indicating whether or not the state has been changed at the correct timing after the alarm is generated is displayed as an icon.

Other display methods may be displayed by changing the symbol color.

Here, the correct timing is, for example, T0 <TA <(TA + δ), where T0 is the alarm occurrence time, TA is the time when the status of the device to be confirmed is changed, and δ is the processing time related to the status change. Refers to the case. It is assumed that δ can be set and changed as appropriate according to device characteristics and system configuration.

However, not all devices that should be checked for changes in state due to the occurrence of an alarm are included in the screen currently being watched by the person operating the plant. In that case, as in the case described in the third to sixth embodiments, the confirmation target device extraction unit 16 in FIG. 10 extracts the confirmation target devices included in the other drawings, and FIG. Each unit 17, 18 and 19 displays the symbol of the confirmation target device in the extracted other drawing on the above screen on which the symbol of the confirmation target device included in the screen being watched is displayed. The display is superimposed so that the two device displays do not overlap each other. Then, the above display method is applied.

Furthermore, since there are many confirmation target devices AA after the alarm is generated, even when the system diagram SF on the screen of the display unit 20 is deformed, all the confirmation target devices AA are overlapped on the original system diagram SF. In some cases, it is difficult to display. In such a case, as illustrated in (2A) of FIG. 6, the units 18 and 19 in FIG. 10 reduce the system diagram SF and move it to one side of the screen. List the timings as a pair.

In addition, when the confirmation target device exists in the same screen, it is possible to highlight the change in state of the confirmation target device (valve B001) by changing the color of the confirmation target device. This function is executed by the deforming unit 19D in FIG.

According to the present embodiment, in the event of an emergency of the plant, such as when an alarm is generated, the plant operator determines the validity of the timing of the state change for the device whose device state is automatically changed with the occurrence of the alarm. The advantage that it can be easily discriminated is obtained.

FIG. 7, which is an example of the present embodiment, shows a case where the current work procedure N of the estimated procedure manual i includes confirming the change tendency of the process value as the operation condition of the device. It is a figure which shows the display method of an apparatus. In this example of FIG. 7, “the pressure is in a stable or rising state” is a condition for operating the device.

Usually, trend graphs are often used to read changes in process values. However, the use of the trend graph requires a resolution and range that allows the plant operator to read the change trend and the value, so it is not possible to display the trend graph without hiding part of the drawing on the display screen. Often difficult.

Therefore, in the present embodiment, the change tendency of the process value is indicated by an information icon (second electronic data) on the monitoring screen of the display unit 20, and the information icon is displayed on the operation target device ( In this example, it is displayed near the valve A001). That is, each of the units 17 and 18 in FIG. 10 calculates the change rate of the process value at a predetermined interval. For example, if the change tendency of the process value is “up”, the information icon of the arrow pointing to the upper right is used. A change tendency is indicated (see (2) in FIG. 7). If the change tendency of the process value is “stable”, the change tendency is indicated by using an information icon such as a horizontal right-pointing arrow. On the other hand, for example, if the change tendency of the process value is neither “increased” nor “stable”, the change tendency is indicated by using the information icon of the arrow pointing to the lower right (see (3) in FIG. 7). In addition, the function part which provides the information whether the expression method of an information icon and operation conditions are satisfied is not restricted above. Regarding the interval for calculating the rate of change, there are a method defined in advance by hand, a method automatically set based on information described in the procedure manual, and the like. The interval can be changed manually based on the plant configuration or the state of equipment operation.

According to the present embodiment, when the process value change tendency is used as the operation condition of the equipment, the change tendency is visualized by the information icon and displayed in the vicinity of the operation target equipment. The conditions can be judged intuitively.

FIG. 8, which is an example of the present embodiment, shows a change tendency of the process values when the process values change tendency is used as the operation condition of the device, as in the seventh embodiment. FIG. 11 is a diagram illustrating an example in which whether or not an operation is possible is determined and each unit 18 and 19 in FIG.

In this example of FIG. 8, when it is determined that the operation condition “pressure is stable or in an elevated state” is satisfied, each unit 18, 19 of FIG. 10 paints the information icon in blue (in FIG. 8). For convenience of illustration, the information icon is indicated by a black circle.) On the other hand, when it is determined that the operation condition is not satisfied, each unit 18 and 19 in FIG. 10 fills the information icon with a different color, for example, red. (In FIG. 8, for convenience of illustration, the information icons are indicated by hatched white circles.) Note that the method of indicating information on whether or not the operation condition is satisfied by coding the information icon is not limited to the above example.

According to the present embodiment, in the case where the change tendency of the process value is used as the operation condition of the device, it is determined whether or not the device can be operated at present (whether the operation condition is satisfied), and the determination result Is represented by a coated information icon, the plant operator can operate the equipment at an appropriate timing.

As described above, the embodiments of the present invention have been disclosed and described in detail. However, the above description exemplifies aspects to which the present invention can be applied, and the present invention is not limited thereto. In other words, various modifications and variations to the described aspects can be considered without departing from the scope of the present invention.
