Description

  The present invention relates to a plant monitoring control apparatus and a control method for monitoring and controlling a power plant.

  Due to remarkable technological and economic development since modern times, various large-scale plants such as power plants have become widespread in various technical fields such as electric power and chemistry, and in recent years, electronic plants such as computers have been applied efficiently. The technology to monitor and control the system has also been generalized.

For example, the technique described in the following Patent Document 1 has been proposed for monitoring and operating a plant using a CRT operation device. That is, the CRT operation device is composed of an operator console provided with a CRT having a touch panel mounted on a display screen, and a CRT operation computer that detects an instruction of the touch panel on the CRT by the operator and outputs a control signal to the process. When the operator selects the operation end on the touch panel, the CRT operation computer predicts the influence of the selected operation device on the plant in advance by inference or simulation, and the operator selects the operation device incorrectly on the CRT screen. This is to prevent erroneous operation.
JP-A-5-143292

  However, the above prior art has the following problems. In other words, the above-described prior art performs simulation specialized for CRT operation, and cannot perform simulation over the whole plant control.

  In the above CRT operation device, the operator can check the correspondence between the result displayed by the simulation and the actual operation content to determine whether or not to perform the operation. The judgment depends on the simulation result, and the operation cannot be performed only by the judgment of the operator.

  Similarly, even if the operator can refer to the guidance display in advance, if an erroneous operation is performed against this guidance, it is left to the operator to determine whether or not the operation is incorrect. There was no means for automatically detecting the correctness of the operation. For this reason, the operator may continue the operation without noticing the erroneous operation.

  Further, in the conventional CRT operation apparatus, even if the contents operated in the simulation mode can be stored, the actual operation contents cannot be stored. Therefore, if there is a mistake in the actual operation content, or if you want to fine-tune setting values or add or delete operation items, perform the procedure again from the beginning and save it as operation content. It was necessary to rework, and the efficiency until the detection of the optimum operation content was poor. Even if you can save and reproduce the contents of the operation in simulation mode, if you cannot confirm the execution state at the time of reproduction, you may not be able to grasp how far the operation has progressed and what state the plant is in. It was.

  Furthermore, even if the operator reproduces the optimum operation content obtained by the simulation, the operation permission condition of the corresponding operation end may not be satisfied depending on the state of the plant. In such a case, the reproduction operation of the content operated in the simulation mode cannot be continued. Therefore, since the operator has recognized that the reproduction operation has been stopped, or the cause cannot be immediately determined, there has been a problem that the operation of the plant is stagnant.

  The present invention has been proposed in order to solve the above-described problems of the prior art, and its purpose is to use simulation results by comparing, monitoring, storing, etc. The object is to propose a highly reliable plant monitoring and control apparatus which prevents operation.

  In order to solve the above-mentioned problems of the prior art, the present invention provides a plant information reading means for reading plant information input from a sensor installed in a plant including each control operation end to be controlled, and the read plant information. Input point information to be stored, operation information for storing various data necessary for controlling the plant by CRT operation, automation information for storing various data for automatically controlling the plant, plant status Display means for notifying display devices of display data such as lists, diagrams, plant or device alarms, and input devices for inputting list, diagram or alarm display requests, CRT operation operation requests or automation operation requests by an operator And an input for notifying the plant control means of the operator's request notified from the input device. And a plant control for notifying the control signal output means of a control signal to the corresponding operation end with reference to the input point information and the operation information when the request from the input means is notified. Input point information and plant input from various sensors of the plant when receiving a request from the input device that the simulation mode requested by the operator is ON or OFF. When the input / output switching means for switching the input / output destination of the control signal for controlling the control signal and the input / output switching means receive a notification that the simulation mode is ON, the input point information is read and the input point information is input. Calculate the simulation value based on the input point information according to the simulation model according to the request from the output switching means. And simulation means that, characterized in that it comprises a I / O simulation value information to be stored in chronological order with the simulation value notified from the simulation means.

  In the present invention as described above, by providing input / output switching means for switching input / output destinations of input point information and plant control signals, simulation not only for CRT operation but also for overall plant control becomes possible. In addition, since the input / output switching means can start the simulation only by switching the output to the simulation means, when the operator performs the control operation of the actual plant, the operation to be performed is immediately simulated. By notifying the operator of the result, the validity of the actual plant control operation to be performed can be confirmed in advance by the plant monitoring control device.

  According to the present invention as described above, it is possible to provide a highly reliable plant monitoring and control device that utilizes simulation results and prevents operations by an operator by comparing, monitoring, and storing the simulation results. .

  Next, the best mode for carrying out the present invention (hereinafter referred to as “embodiment”) will be specifically described with reference to the drawings.

(1) First Embodiment [Configuration]
A plant monitoring control apparatus 10 according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 4.

  As shown in FIG. 1, the plant monitoring and control device 1 of the first embodiment receives an input from an operator, and outputs an operation function output to the operator through a display device, and various information such as an input point of the plant. It comprises a database function to be stored, a simulation function for simulating a plant, and a plant control means 6 for controlling these functions. The plant monitoring and control apparatus 1 also includes an input / output switching unit 12 for switching the simulation function ON or OFF, a plant information reading unit 11 for reading plant information input from a sensor installed in the plant, and a plant control unit. When the control signal is received from the input / output switching means 12 from 6, the control signal output means 10 outputs the control signal to the corresponding operation end.

  The operation function includes, as output means, a display device 2 for displaying the plant status in a list or a diagram, displaying plant or device alarms, and selecting an operation content when the operator performs CRT operation, and plant control means. 6 includes display means 4 for notifying the display device 2 of data such as a list of plant states received from 6 and data such as diagrams and device alarms. In addition, as an input means, a touch panel (installed in the display device 2 in this embodiment), a keyboard, etc., where an operator inputs a list of plants, a display request for diagrams and alarms, a CRT operation operation request and an automation operation request, and the like. The input device 3 and the input means 5 for notifying the plant control means 6 of the operator's request notified from the input device 3.

  The database function includes input point information 9 for storing plant information read from the plant information reading means 11 using an ID as a key, and operation information 7 for storing various data necessary for controlling the plant by CRT operation. And automation information 8 storing various data for automatically controlling the plant.

  The input / output switching means 12 is a means for receiving a simulation mode ON or OFF signal from the input means 5 and transmitting various information to the simulation means 13 or the plant control means 6 in response to the ON or OFF signal. .

  For example, when the input / output switching unit 12 receives a signal for turning off the simulation mode, the input / output switching unit 12 notifies the simulation unit 13 of this signal, reads the input point information 9 and notifies the plant control unit 6, and performs plant control. The control signal from the means 6 is notified to the control signal output means 10.

  When a signal for turning on the simulation mode is received, this signal is notified to the simulation means 13, the I / O simulation value information 14 is read and notified to the plant control means 6, and from the plant control means 6. When the control signal is notified, a control output signal is notified to the simulation means 13.

  The simulation function is composed of simulation means 13 and I / O simulation value information 14. The I / O simulation value information 14 stores simulation results notified from the simulation means 13 in time series. When the simulation unit 13 receives, for example, a notification of a signal for turning on the simulation mode from the input / output switching unit 12, the simulation unit 13 reads out the plant information stored using the ID as a key from the input point information 9, and outputs the result as I / I. When the control output signal is received from the input / output switching means 12, the simulation result is calculated according to the simulation model, and the calculation result is stored in the I / O simulation value information 14. It is.

  When there is a display request or control request by the operator from the input means 5, the plant control means 6 extracts necessary information from the operation information 7, the automation information 8 and the input / output switching means 12 and executes the display request or control request. Means. Specifically, when a display request such as a plant state list or diagram or a plant or device alarm is received from the input means 5, the corresponding data is displayed with reference to the input point information 9, the automation information 8 or the operation information 7 or the like. It is configured to notify the means 4.

  Similarly, when an automation control request is notified from the input means 5, the conditions of automatic plant control are sequentially checked with reference to the input point information 9 and the automation information 8. The signal output means 10 is configured to notify a control signal to the corresponding operation end. Further, when a CRT operation request is notified from the input means 5, the control signal output means 10 is notified of a control signal to the corresponding operation end with reference to the input point information 9 and the operation information 7. ing.

[Function and effect]
The effect of the plant monitoring control apparatus 1 having the above configuration will be described with reference to FIGS. FIG. 2 is a flowchart showing processing of input point information of the input / output switching means 12. First, the input / output switching means 12 determines whether the simulation mode is ON or OFF from a signal input to the input means 5 by the operator via the input device 3 (step 201).

  That is, if the signal indicates that the simulation mode is OFF, the input / output switching means 12 notifies the simulation means 13 that the simulation mode is OFF (step 202) and from the input point information 9 Information relating to the plant instructed to input using the ID as a key is read (step 203), and this input point information is notified to the plant control means 6 (step 204).

  On the other hand, when the signal indicates that the simulation mode is ON, the input / output switching unit 12 notifies the simulation unit 13 that the simulation mode is ON (step 210), and from the I / O simulation value information 14 Information on the plant to be simulated is read (step 212), and this simulation value information is notified to the plant control means 6 (step 213).

  Next, when the notification from the input / output switching unit 12 to the control unit 5 is made, the control unit 5 notifies the control signal output unit 10 or the simulation unit 13 via the input / output switching unit 12. The control output switching process in the input / output switching means 12 will be specifically described with reference to the flowchart of FIG.

  First, the input / output switching unit 12 determines whether there is a control output request from the control unit 5 (step 301). If there is no control output request (NO), the process returns to the next control output request. When the control output is notified (YES), the control signal is received and it is determined whether the current simulation mode is ON or OFF (step 302). If the simulation mode is OFF (YES), the control signal output means 10 is notified of the control signal (step 303). On the other hand, when the simulation mode is ON (NO), a control signal is notified to the simulation means 13 (step 304).

  As described above, when the control signal is transmitted from the input / output switching means 12 to the simulation means 13 or the control signal output means 10, the simulation means 13 or the control signal output means 10 operates as follows. First, as shown in the flowchart of FIG. 4, the simulation unit 13 determines whether the current simulation mode is ON or OFF (step 401). If the simulation mode is OFF (YES), the process returns to the original and the next simulation mode ON notification is monitored.

  If the simulation mode is ON (NO), it is determined whether the simulation mode at the previous monitoring is ON or OFF (step 402). If the previous simulation mode is OFF (YES), the input point information 9 is read as a new simulation (step 403), and the previous simulation value is written to the I / O simulation value information 14 (step 404). ) Wait for the control output to be notified. If the previous simulation mode was ON (NO), the control waits for notification of the control output.

  Next, when a control output notification is received (YES in step 405), the contents of the control output are written in the I / O simulation value information (step 406), and the control contents are simulated according to the original simulation model (step 407). The result is written in the I / O simulation value information 14 (step 408). On the other hand, when the control output notification is not made (NO in step 405), the process returns to step 401 and the above process is repeated.

  As described above, according to the plant monitoring control apparatus 1 according to the present embodiment, not only the CRT operation but also the input / output switching means 12 that switches the input / output destination of the input point information and the control signal of the plant, Simulation over the entire plant control becomes possible.

  In addition, since the input / output switching unit 12 can start the simulation only by switching the output to the simulation unit 13, when the operator performs the control operation of the actual plant, the simulation of the operation to be performed is immediately performed. By notifying the operator of the result, the validity of the control operation of the actual plant to be performed from now on can be confirmed in advance by the plant monitoring control device.

(2) Second Embodiment Next, a plant monitoring control apparatus according to a second embodiment of the present invention will be described with reference to FIG. 1, FIG. 5 and FIG. The plant monitoring and control apparatus 20 according to the present embodiment uses an input / output switching means 21 obtained by improving the input / output switching means 12 in the first embodiment, as shown in parentheses in the overall configuration diagram of FIG. It was.

  When the input / output switching means 21 receives from the input means 5 an I / O simulation value comparison display request for comparison between the input point information and the I / O simulation information, the I / O simulation value information 14 is first sent to the plant control means. 6 and then the information of the input point in the actual plant is notified from the input point information 9 to the plant control means 6.

  In the flowchart of FIG. 5, as shown in the input point information processing of the input / output switching means 21, the input / output switching means 21 determines whether the I / O simulation value comparison display signal sent from the input means 5 is ON or OFF. Determination is made (step 501). If the I / O simulation value comparison display signal is ON (NO), the I / O simulation value comparison display signal is turned OFF (step 502), and the simulation value information is obtained from the I / O simulation value information 14. Read (step 503), and subsequently notify this information to the plant control means 6 (step 504).

  Thereafter, the actual plant information read by the plant information reading means 11 is read from the input point information 9 using the ID as a key (step 505), and this input point information is notified to the plant control means 6 (step 506). In addition, once notified, the latest input point information 9 is notified to the plant control means 6 as needed.

  The plant control means 6 that has received such a notification first outputs the simulation result information sent from the I / O simulation value information 14 to the display means 4, and then receives the input point information sent from the input point information 9. Output to the display means 4. Thereby, after the simulation result information is displayed on the display device 2, the input point information of the actual plant is displayed so as to overlap therewith. The input / output switching means 21 notifies the plant control means 6 of the latest input point information at any time, and the display apparatus 2 displays the latest result of operating the actual plant.

  On the other hand, if the I / O simulation value comparison display signal is OFF (YES in step 501), the input / output switching means 21 notifies the simulation means that it is OFF (step 510), and then input. The input point information is read from the point information 9 (step 505), and this input point information is notified to the plant control means (step 506).

  An example of the input point information comparison display screen (trend graph) of the display device 2 output as described above is shown in FIG. As described above, when the operator requests to display the input point information comparison screen via the input device 3, the screen shown in the figure is displayed. First, trend graphs 604 and 606 at the time of simulation are drawn, and then trend graphs 603 and 605 at the time of online are drawn. Further, a simulation value 602 corresponding to the current value 601 at the input point when online is displayed.

  Although the graph number is displayed at the right end of each trend graph, the colors and the colors of both graphs are displayed on the screen so that the online trend graph 73 and the simulation trend graph 74 can be distinguished at a glance. The line type is changed, and an alphabet (S) is displayed next to the graph number of the trend graph 74 at the time of simulation to distinguish them.

  As described above, according to the plant monitoring control device according to the present embodiment, the input point information of the actual plant and the I / O simulation value information that is the simulation result information of the plant simulation device are displayed on the same screen. The operator can compare and confirm the simulation operation and the online actual operation. Thereby, an operator's erroneous operation can be prevented.

(3) Third Embodiment A plant monitoring control device 30 according to a third embodiment of the present invention will be described with reference to FIGS. FIG. 7 is a diagram illustrating a configuration of the plant monitoring control device 30 according to the present embodiment. The plant monitoring control device 30 includes input point comparison means 31 and comparison input point information 32 in addition to the configuration of the plant monitoring control device 1 or 20.

  The input point comparison means 31 compares information on the actual plant and information on the simulation results as needed, and displays a signal that blocks the operator's operation on the input device 3 in the plant control means 6 when a mismatch exceeding the allowable range occurs. A signal for requesting message display to block the operation in the apparatus 2 is notified. On the other hand, the comparison input point information 32 stores the allowable range of the difference between the I / O simulation value information 14 and the input point information 9.

  Next, the operation of the input point comparison means 31 and the comparison input point information 32 will be described. FIG. 8 is a flowchart showing the input point automatic comparison process of the input point comparison means 31. First, the input point comparison means 31 acquires the allowable range value of the difference between the simulation result information and the actual plant information from the comparison input point information 32 stored in advance (step 801). The simulation result information is read (steps 802 and 803), and the actual plant input point information obtained from them is compared with the value of the simulation result information within an allowable range as needed (step 804).

  If a mismatch between the two values exceeds the allowable range (NO in step 804), a signal for blocking the operation of the operator input device 3 and a message display of the operation block are displayed on the plant control means 6 as a display device. 2 is notified of the required signal (step 805). On the other hand, if the error between the two values is within the allowable range (YES in step 804), the process returns to step 802 and the above processing is repeated.

  FIG. 9 shows a screen example of the operation block message output to the display device 2 in this way. As shown in the figure, in the operation block message window 101, a message indicating that the operation has been blocked due to the input point name 102 of the input point where the value mismatch exceeding the allowable range has occurred and the value mismatch has occurred. 103 is displayed. The operation block message window 101 disappears when the delete button 104 is pressed.

  As described above, according to the plant monitoring control apparatus 30 according to the present embodiment, the input point information of the actual plant and the I / O simulation value information of the plant simulation apparatus are compared at any time, and a mismatch exceeding the allowable range is detected. Then, since the operator's operation is blocked and the mismatch state is notified at the same time, it becomes possible to prevent an illegal control signal from being output due to the continuation of the erroneous operation.

  Therefore, when there is a difference between the simulation result and the actual online operation, the operation is blocked, and at the same time, the operator is notified of the mismatch condition, thereby preventing the operator from continuing the erroneous operation.

(4) Fourth Embodiment A plant monitoring control device 40 according to a fourth embodiment of the present invention will be described with reference to FIGS. 10 to 13. FIG. 10 is a diagram showing the configuration of the plant monitoring control apparatus according to the embodiment of the present invention. In addition to the configuration of the first embodiment, the plant monitoring control device 40 includes an input operation storage unit 41, operation history information 42, and an input operation reproduction unit 43.

  The input operation storage means 41 receives the control output signal from the input / output switching means 12 for notifying the control output signal in the simulation mode, notifies the simulation means 13 of this signal, and performs storage processing of the control output signal. It is.

  The operation history information 42 is means for storing the control output signal in time series. Further, the input operation reproduction unit 43 notifies the input unit 5 of the operation content of the control output signal stored in the operation history information 42 in accordance with the reproduction instruction from the input device 3, and the operation content is input to the input operation storage unit 41. It is means for notifying that reproduction is in progress.

  Note that the input device 3 of the present embodiment is provided with a button indicating a reproduction instruction, and is configured to notify the input operation reproduction means 43 when the reproduction button is pressed.

  FIG. 11 is a diagram showing an internal configuration of the operation history information 42. As shown in FIG. 9A, the operation history information 111 is arranged in time series from the operation history data (1) to the operation history data (N), and one operation history data has the data structure of FIG. As shown in Example 112, the data includes operation date / time (year / month / day / hour / minute / second), screen number, TAG number (operation end number), operation type, and operation value.

  The operation date / time refers to the date / time operated by the operator, and the screen number refers to the number of the screen on which the operator has issued an operation instruction. The TAG number refers to the number of the operation end operated by the operator, and the operation type is a type indicating what operation the operator has performed on the operation end. Each operation such as “Cancel”, “Open”, “Close”, “Stop”, “Increase”, “Decrease”. The operation value is a value output to the operation end, which means ON or OFF in the case of contact output, and information such as a target value, a set value, and a change rate in the case of analog output.

  Next, the operation of the present embodiment will be specifically described with reference to FIGS. First, the operator switches to the simulation mode, and selects “open” of TAG 1 and presses the “execute” button, as shown in the example of the conventional CRT operation method of FIG. To implement. These operations are notified from the input device 3 to the input means 5, and are notified to the input operation storage means 41 via the plant control means 6 and the input / output switching means 12.

  As shown in the flowchart of FIG. 12, the input operation storage means 41 first checks whether the input / output switching means 12 has been switched from the online mode to the simulation mode, that is, whether the simulation mode has been switched from OFF to ON ( If it has changed (step 1201), the operation history information 42 is cleared to zero (step 1202).

  Thereafter, since the operation content in the simulation mode is notified from the input / output switching means 12, it is received (step 1203). If the input operation is not being reproduced (NO in step 1204), the operation content is stored in the operation history information 42. (Step 1205), and the operation contents are notified to the simulation means 13 (step 1206). If the input operation is being reproduced (YES in step 1204), the operation history information 42 is not saved and only the notification to the simulation means 13 is performed (step 1206).

  After confirming the validity of the operation in the simulation operation, the operator returns to the online mode and performs the actual operation. At this time, the operator presses the reproduction button of the input device 3. When the reproduction button is pressed, the input device 3 notifies the input operation reproduction means 43 that the reproduction button has been pressed.

  Upon receiving the reproduction notification, the input operation reproduction means 43 starts the input operation reproduction process in response to a reproduction instruction from the input device 3, as shown in the flowchart of FIG. 13 (START). First, the input operation reproduction means 43 notifies the input operation storage means 41 that the input operation is being reproduced (step 1301). Next, the operation history data (i) is extracted from the operation history information 42 (step 1302), and the operation date / time (i) is stored in the operation history information 42 as the previous operation date / time (Tn) and the current operation date / time (Tp). (Step 1303).

  Then, the operation content (i) is notified to the input means 5. When this notification is made, it is first determined whether or not the previous operation date (Tn) is 0 (step 1304). YES), the operation content is notified at intervals of the operation date and time (relative time) (step 1305). That is, the operation content of the operation history data (2) is notified to the input means 5 with a time difference between the operation date and time of the operation history data (1) and the operation date and time of the operation history data (2) in FIG. .

  Then, this operation date and time (i) is stored as the current operation date and time Tp (step 1306), and then new operation history data (I), where I = i + 1 is extracted (steps 1307 to 1308), and the operation date and time (I) Is stored in the operation history information 42 (step 1309).

  Thereafter, returning to step 1304, the same processing is repeated until the previous operation date / time (Tn) of the operation history data becomes zero (steps 1304 to 1308), and when the previous operation date / time becomes zero, the operation history data The reproduction process is considered to be finished (NO in step 1304). Then, in order to notify the input operation storing means that the reproduction process has been completed, a reproduction end notification is made (step 1310), and the processing of the input operation reproduction means is ended (END).

  As described above, the operation details can be notified at the same interval as the simulation operation, so that not only the operation content but also the operation speed can be faithfully reproduced. Plant control can be performed with the same operation content.

  In the above description, the operation content performed in the simulation mode is described as being reproduced in the online mode. However, when the same operation is desired to be performed again in the simulation mode, that is, the simulation content is desired to be reproduced in the simulation mode. In this case, since the input operation reproducing unit 43 notifies the input operation storing unit 41 that the reproduction is being performed, the input operation storing unit 41 is notified from the input / output switching unit 12 if the reproduction is being performed. Only the operation content is notified to the simulation means 13, and the operation history information 42 can be saved. Accordingly, the contents of the reproduction operation are not stored redundantly.

  As described above, according to the plant monitoring control device 40 according to the present embodiment, it is possible to save the contents operated in the simulation mode and automatically reproduce them. Therefore, when the operator confirms the validity of the operation in the simulation mode and then performs the same operation in the online mode, it is possible to prevent erroneous operations by automatically reproducing the contents operated in the simulation mode. Become.

(5) Fifth Embodiment A plant monitoring control apparatus 50 according to a fifth embodiment of the present invention will be described with reference to FIGS. 14 to 16. FIG. 14 is a diagram illustrating a configuration of the plant monitoring control apparatus according to the present embodiment. The plant monitoring and control apparatus 50 according to the present embodiment includes an input operation display unit 51 and an input operation editing unit 52 in addition to the fourth embodiment.

  The input operation display means 51 receives an editing request from the operator in the input device 3, reads the operation history information 42, and notifies the display means 4 of the input operation list, thereby displaying the input operation list on the display device 2. The input operation editing means 52 is means for updating the operation history information 42 in response to an operator edit update notification from the input device 3. In the present embodiment, an edit button for requesting editing of an input operation is provided on the display device 2, and the processing of the present embodiment is configured to be started by pressing this button. .

  Next, the operation of this embodiment will be described with reference to the flowchart of FIG. As shown in the figure, the input operation display means 51 stands by until there is an editing request from the operator by the input device 3, and when there is an editing request from the operator by the input device 3 (in step 1501). YES), the operation history information 42 is read (step 1502), and the display means 4 is notified to display the input operation list display screen of the operation history information 42 on the display device 2 (step 1503).

  FIG. 16 is an example of an input operation list display screen for editing an input operation. In this screen, the operation history data (1) to (N) acquired as the operation history information 42 by the input operation display means 51 is added with the relative time of the operation based on the operation of (1), and the operation history information list is displayed. 161 are displayed in the order of operation. Of the N operation history data displayed in the operation history information list 161, any operation history data (X) to be edited is selected, and the operator presses the change button 162 with the input device 3 such as a touch mouse. Then, detailed operation content for each operation history data acquired as the operation history data 166 is displayed in the operation history data 166.

  The operator changes or corrects the detailed contents of the operation history data 166 using the input device 3. Further, when the save button 167 is pressed by the input device 3, these changes are notified to the input operation editing means 52. When arbitrary operation history data (X) is selected from N displayed in the operation history information list 161 and an add-up button 163 and an add-down button 164 are pressed, Or new operations can be added below.

  Detailed information regarding this operation is input to the operation history data 166 and can be set by pressing a save button 167. Further, of the operation history data (N) displayed in the operation history information list 161, any operation history data (X) to be edited is selected, and when the delete button 165 is pressed, the selected operation history data ( X) can be deleted from the sequence of operations.

  In this screen example, only one group is handled as a group having operation history data. However, it is possible to further increase the hierarchy and perform editing as a plurality of groups. At this time, the group may be handled as a hierarchy one level higher in the operation history information list 161.

  FIG. 17 is a flowchart of the input operation editing means 52 for updating the edited input operation to the operation history information 42 of FIG. The input operation editing means 52 receives the notified operation history information edit update notification when the operator presses the save button 167 (YES in step 1701). Next, the change contents of the operation history data 166 are acquired (step 1702), and the operation history data 42 of the operation history information 42 is rewritten and updated (step 1703).

  The above operation will be described using a specific example. That is, the operator switches to the simulation mode, selects the “open” button 241 of the TAG 1 on the CRT operation operation screen of the input device 2 as shown in FIG. 24, and “open” by the “execute” button 242 at the operation end. Is executed. At this time, the series of operations is stored as operation history information 42 by the input operation storage unit 41. The saved input operation is the operation history data 42 of the operation history data (1) as data of operation date and time, screen number of the CRT operation operation screen, TAG number of TAG1, and operation type “open”. Further, the operation history data 42 of the operation history data (2) is data such as operation date and time, screen number of the CRT operation operation screen, TAG number of TAG1, and operation type “execution”.

  Thereafter, when the operator requests editing using the edit button of the input device 3, an input operation editing screen as shown in FIG. 16 is displayed on the display device 2, and the operation history information 161 includes, for example, operation history data (1 ) And (2) are displayed.

  Here, when the operator selects the operation history data (1) and presses the change button 162, the operation history data 166 includes a relative time with respect to the operation history data (1), that is, 00:00:00, CRT The screen number of the operation operation screen, the TAG number of TAG1, and the data of the operation type “open” are displayed. For example, the operator may change the TAG number of TAG1, set another TAG, or set the operation type “open” to “closed”. After the change, if the save button 167 is pressed, the operation history information 42 is updated, and if the operator requests editing again with the edit button of the input device 3, the operation history contents having the contents edited and saved earlier are displayed. It will be.

  As described above, according to the plant monitoring and control apparatus 50 according to the present embodiment, the operation contents stored by the input operation display unit 51 are displayed in a list and can be edited by the input operation editing unit 52. The operator can make arbitrary changes after displaying the stored series of operation contents on the screen. Therefore, even when the optimum operation cannot be performed at the time of saving the operation or when it is desired to finely adjust the operation content, it is possible to change to the optimum operation without re-starting the simulation from the beginning.

  In addition, when another operation is to be created from the saved operation content, this editing function allows a new operation to be created and saved efficiently and instantaneously without repeating the simulation.

(6) Sixth Embodiment A plant monitoring control device 60 according to a sixth embodiment of the present invention will be described with reference to FIGS. FIG. 18 is a diagram showing a configuration of the plant monitoring control device 60 of the present embodiment. The plant monitoring control device 60 of this embodiment includes a progress state display means 61 in addition to the fifth embodiment.

  The progress state display unit 61 reads the operation history information 42 and displays the operation content list on the display unit 2 by notifying the display unit 4, and displays the progress state based on the notification of the operation progress state from the input operation reproduction unit 43. Is displayed on the display device 2 by notifying the display device 4 of the above. In the present embodiment, the processing is started by a notification from the input operation reproducing unit 43 that notifies that the reproduction is being performed in accordance with a reproduction instruction from the input device 3.

  Next, the operation of the progress state display means 61 in this embodiment will be described using the flowchart of FIG. As shown in the figure, the progress state display means 61 stands by until there is a reproduction instruction from the operator by the input device 3 (step 1903), and when there is a reproduction instruction from the operator by the input device 3 (step 1). In step 1904, the progress state display unit 61 receives a notification during reproduction from the input operation reproduction unit 43 (step 1905), reads the operation history information 42, and displays a progress state display screen for the display unit 4 on the display device 2. Notification is made to display (step 1906). Then, every time the operation progress notification is received from the input operation reproduction unit 43, the progress state display unit 61 notifies the display unit 2 of the display notification of the operation content and the progress state on the display device 2.

  FIG. 20 is an example of a progress state display screen that displays the progress state of the reproduction operation. On this screen, the progress state display means 61 acquires the operation history data to be reproduced from the operation history information 42 and displays the operation contents of the operation history data in the operation item list 201 in the order of operations. The input operation reproduction means 43 notifies the operation progress notification to the progress status display means 61 every time the operation content is reproduced, and the progress status display means 61 displays the progress status display and the operation item display currently in progress. Is notified to display the progress display screen on the display device 2.

  The operation of the present embodiment performed based on the processing procedure of the progress state display means 61 as described above will be described using a specific example with reference to the flowcharts of FIGS. 19 (a) and 19 (b).

  First, the operation history information 42 is created according to the processing procedure described in the fourth embodiment. Next, the operator returns to the online mode and performs the actual operation. At this time, as shown in FIG. 19B, the processing is started by a reproduction instruction by pressing the reproduction button of the input device 3 (START). ). Thereby, the input device 3 notifies the input operation reproducing means 43 that the reproduction button has been pressed (step 1910). When the input operation reproducing unit 43 receives the reproduction notification, the input operation reproducing unit 43 notifies the progress state displaying unit 61 of the reproduction in progress (step 1911).

  As shown in FIG. 19A, the progress state display unit 61 stands by until the notification during reproduction is notified (step 1901), and when the notification during reproduction is received, the operation history information 42 is used during simulation mode. The content of the operation performed is taken out (step 1902), the content of operation is transmitted to the display means 4 (step 1903), and the display means 4 displays a progress display screen on the display device 2. The input operation reproduction unit 43 sequentially notifies the input unit 5 of the operation contents from the operation history data (1), and sequentially notifies the progress state display unit 61 that the operation has progressed as a progress notification.

  On the other hand, when the input operation reproduction means 43 receives the reproduction notification, the input operation reproduction means 43 first notifies the input operation storage means 41 that the input operation is being reproduced (step 1912). Next, the operation history data (i) is extracted from the operation history information 42 (step 1912), and the operation date / time (i) is stored in the operation history information 42 as the previous operation date / time (Tn) and the current operation date / time (Tp). (Step 1913).

  Then, the operation content (i) is notified to the input means 5. When this notification is made, it is first determined whether or not the previous operation date (Tn) is not 0 (step 1914). YES), the operation details are notified with an interval (relative time) between the operation dates (step 1916). That is, the operation content of the operation history data (2) is notified to the input means 5 with a time difference between the operation date and time of the operation history data (1) and the operation date and time of the operation history data (2) in FIG. . Further, the progress of the operation is sequentially notified to the progress display means 61 as a progress notification (step 1916).

  The progress state display unit 61 highlights the operation item being reproduced every time a progress notification is received, and displays the progress state of the progress state display screen as complete if it is a completed item, and as being executed if it is being reproduced. 4 is displayed (step 1905) and displayed on the display device 2. As a result, the operator can confirm how far the reproduction operation has been executed.

  At this time, the input operation reproduction means 43 stores the operation date / time (i) as the current operation date / time Tp (step 1917), and then extracts new operation history data (I), where I = i + 1 (step 1918). The operation date / time (I) is stored in the operation history information 42 (step 1919). Thereafter, returning to step 1914, the same processing is repeated until the previous operation date and time (Tn) of the operation history data becomes zero (steps 1914 to 1919), and when the previous operation date and time becomes zero, the operation history data The reproduction process is considered to be finished (NO in step 1914).

  Then, the input operation reproduction unit 43 performs a reproduction end notification to notify the input operation storage unit that the reproduction process has ended (step 1919), and further notifies the progress state display unit 61 of the reproduction end notification. (Step 1921), the process is completed (END).

  Upon receiving the reproduction end notification (step 1906), the progress state display means 61 requests the display means 4 to display the operation completion in order to display that the reproduction operation has been completed. 2 is displayed.

  In the above description, the operation content performed in the simulation mode is described as being reproduced in the online mode. However, there is a case where the same operation is desired to be performed again in the simulation mode. This case can also be realized by the same processing as described above.

  As described above, according to the plant monitoring control apparatus 60 according to the present embodiment, the progress state display means 61 displays a series of operation contents once stored on the screen and then displays the progress state of the reproduction operation. The operator can grasp the progress state, can respond quickly to unforeseen circumstances, and can operate the plant with high safety.

  The plant control means 71 is configured to perform a process of notifying the stop of the reproduction operation when a factor for stopping the progress of the reproduction operation occurs. Further, the stop factor display means 72 receives the stop notification of the reproduction operation from the plant control means 71, and the detailed information of the operation that has been stopped from the operation history information 42, the cause of the stop of the progress from the operation information 7 and the automation information 8. By reading the information and notifying the display means 4, the display device 2 is configured to display the operation end at which the reproduction operation is stopped and the factor thereof.

  Next, the operation of the present embodiment will be described with reference to FIGS. FIG. 22 shows a process from when the stop factor display means 72 receives a stop of the progress of the plant operation from the plant control means 71 until it notifies the operator of the cause of the stop of the plant.

  As described in the fourth embodiment, the operation selected from the operation history information 42 obtained by the simulation is faithfully reproduced by the input operation reproducing unit 43. The operation requested to be reproduced is notified to the plant control means 71 via the input means 5 and controlled based on control information such as operation information 7, automation information 8 and input point information 9 (FIG. 21). reference).

  Further, the plant control unit 71 performs an operation based on the operation history information 42. The reproduced operation history information 42 is displayed by the progress state display unit 61 as shown in the sixth embodiment. Will be notified.

  However, when the plant state at the time of reproduction does not change from the plant state at the time of simulation, it is executed according to the selected operation history information 42, but when a large change has occurred in the plant state, It is conceivable that an optimal operation cannot be performed or a malfunction of the plant occurs.

  In such a case, the reproduction operation is interrupted by the plant control means 71, and this operation interruption is notified from the plant control means 71 to the stop factor display means 72. Upon receipt of the stop notification, the stop factor display means 72 is stopped by the notification to the progress state display means 61, and the operator can confirm that the reproduction operation has been interrupted.

  Further, the stop factor display means 72 reads the investigation history information and the stop factor information (step 2202), and creates the reproduction operation interrupted from the operation history information 42 and the operation information 7 and the cause thereof as display data (step 2203). As shown in the screen example of FIG. 23, the display unit 4 is notified (step 2204).

  As described above, according to the plant monitoring and control apparatus 70 of the present embodiment, when the factor that causes the plant control unit 71 to stop the progress of the reproduction operation occurs, the process of notifying the stop of the reproduction operation is performed as the stop factor display unit. 72, even if the reproduction operation is interrupted depending on the state of the plant, the operator can confirm the interrupted operation end and the cause thereof, and the reproduction operation can be promptly restarted. Driving is possible.

  Therefore, when the actual plant information is input and the plant reproduction operation is executed, when the reproduction operation stops depending on the state of the plant, the operator can recognize that the reproduction operation has stopped and can quickly determine the cause of the stoppage. By doing so, plant operation can be resumed promptly.
