Description

  The present invention relates to a monitoring control system for various plants, and more particularly, to an operation support function provided therein.

  2. Description of the Related Art In recent years, in a monitoring control system for various plants such as a power plant, a software type monitoring control panel (software panel) has been introduced instead of a conventional hardware type monitoring control panel. In the software board, control of equipment in the plant, display of measured values, and the like are performed using a graphical user interface (GUI) instead of mechanical equipment such as a conventional switch or indicator. Thereby, the monitoring control system can be reduced in size, and the operation load on the operator (monitorer) can be reduced.

  On the other hand, the functions required for the plant monitoring and control system are becoming more complicated as the capacity of the plant is increased and the functions are increased. In many plant monitoring and control systems, an operation support system called an expert system is introduced in order to reduce an operator's operation load due to complicated functions.

  The expert system mainly supports operations for performing non-daily tasks such as dealing with plant accidents and plant inspections. Examples of expert system functions include an accident type determination function based on various measured values (plant measured values) in the plant, an operation manual browsing function defined for each accident type, and an operation guidance function based on an operation history ( Operation support function) (for example, Patent Document 1).

  For example, when a plant accident occurs, the plant monitoring control system performs an automatic operation based on the accident type determination result by the expert system, or the operator browses an operation manual provided from the expert system and performs a manual operation. Further, when the operator performs manual operation, the expert system provides operation guidance, so that the operator can surely perform an appropriate operation.

  According to the plant monitoring and control system equipped with such an expert system, in the case of extraordinary work such as when a plant accident occurs, the operator can search for the necessary operation manual from the library and perform operations while turning the pages. This is particularly effective when an urgent operation or an operation whose execution timing is important is involved.

JP 2006-39648 A JP-A-1-199212

  Conventionally, an expert system employs an operation support device that operates based on a program composed of conditional statement data (IF-THEN statement) in the form of “IF [condition] THEN [operation]”. In other words, the conventional operation support apparatus is configured to perform an operation (for example, an operation instruction or automatic operation to an operator) defined by the THEN statement when the plant state or operation history satisfies the conditions defined by the IF statement. It was.

  However, as the functions of the plant and the functions of the plant supervisory control system become more complex, it becomes difficult to configure only the data of the IF-THEN statement in the following cases.

  First, the operation procedure is not clear. For example, when a condition that two operations A and B having an arbitrary operation order are executed is described in the IF statement, not only the case where the operations A and B are performed in the order, but also the operations B and A are performed in the order. Three conditional statements must be prepared: the case where the operation A and the operation B are performed in parallel. If the number of operations in any order increases, the number of necessary conditional statements increases in the factorial order, making it difficult to manage data and search for conditional expressions. As a result, it becomes difficult for the expert system to provide correct operation guidance.

  The next possible case is when a plurality of operations are performed in an unexpected procedure of the expert system. For example, a case where the operator starts an operation specified in the THEN statement prior to the satisfaction of the IF statement condition, or an operation corresponding to the THEN statement (corresponding operation) according to the satisfaction of the IF statement condition. In this case, the operator performs another operation. In the former case, when the condition of the IF statement is satisfied, there is a possibility that the already performed operation is guided again. In the latter case, it is necessary to prepare further guidance for resuming the handling operation left on the way, and the expert system becomes very complicated to realize it. As a result, data management becomes increasingly difficult and it becomes difficult for the expert system to provide correct operation guidance.

  The present invention has been made to solve the above-described problems. A plant capable of providing appropriate operation guidance even when a complicated operation procedure is included or the operation sequence may be changed by an operator. An object is to provide a supervisory control system.

The plant monitoring control system according to the present invention includes a measurement value database in which various measurement value data in a plant is accumulated, an operation history database in which operation history data of the plant monitoring control system is accumulated, and one or more operation steps. Corresponding to each of the individual operation database storing the individual operation data indicating the operation procedure of the specified individual operation, the past operation procedure obtained based on the measurement value data and the operation history data, and the individual operation data The operation procedure scoring unit that scores the degree of similarity according to the length of the matching part with the individual operation to be performed, the individual operation currently being performed is estimated based on the similarity, and the next operation should be performed based on the estimation result A recommended operation selection unit for selecting recommended operations and a user interface capable of presenting the selected recommended operations to the operator. And a part, the individual operation data, and operation contents identifier representing the content of each operation step of the individual operations, having one or more hierarchical structure, and sequence identifier indicating the order in which each operation step is performed, the Including a combination of a condition identifier indicating a condition for shifting from the operation step to the next operation step, and the condition identifier indicates a condition for shifting to the next operation step when all of the predetermined operation steps are completed. And an “OR” identifier indicating a condition for shifting to the next operation step when any of the predetermined plurality of operation steps is completed, and the operation procedure scoring unit includes the same The order in which the plurality of operation steps associated with the “AND” identifier are performed is not considered in the scoring of the similarity, and the plurality of operations associated with the same “OR” identifier is performed. Which is carried the number of steps is not considered to scoring the similarity.

  In the plant monitoring and control system according to the present invention, the total number of individual operation models necessary for selecting an appropriate recommended operation corresponds to the number of individual operations specified in an operation manual or the like. This relationship does not depend on the assumed complexity of the operating procedure. In the conventional operation support system configured by the IF-THEN statement, the number of conditions specified by the IF statement becomes enormous as the assumed operation procedure becomes complicated, making it difficult to provide correct operation guidance (selecting an appropriate recommended operation). However, according to the present invention, this problem is not involved.

<Embodiment 1>
FIG. 1 is a block diagram of a monitoring control system according to Embodiment 1 of the present invention. The monitoring and control system targets plant equipment 170 for monitoring and control, and includes a recommended operation selection device 110, a central control device 120, a plant measurement value collection device 130, an input / output control device 140, a plant measurement value database 150, and an operation history. A database 160 and an input / output device 180 are provided.

  The central control device 120 performs operation monitoring and operation control of the plant equipment 170 based on an operation by an operator or an operation by automatic control. The plant measurement value collection device 130 collects various measurement value data (plant data) from a measuring instrument attached to the plant equipment 170 and stores it in the plant measurement value database 150.

  The input / output device 180 is a user interface and is controlled by the input / output control device 140. The input / output control device 140 provides monitoring data of the plant equipment 170 output from the central control device 120 to the operator via the input / output device 180, or an operation corresponding to an operation command input to the input / output device 180 by the operator. Send the signal to 120 to the central controller. Further, the input / output device 180 takes out predetermined data representing an operation type and the like from the operation signal and stores the data in the operation history database 160 as operation history data.

  The recommended operation selection device 110 determines the type of operation currently being performed based on the plant data stored in the plant measurement value database 150 and the operation history data stored in the operation history database 160, and This is to select the recommended operation (recommended operation). The recommended operation selection device 110 includes an individual operation database 111, an operation procedure scoring unit 112, a recommended operation selection unit 113, and an operation selection result database 114.

  The individual operation database 111 is a database in which a plurality of operation procedure data (individual operation data) of a series of operations (referred to as “individual operations”) defined by one or more operation steps are registered. The operation procedure scoring unit 112 scores each of a plurality of individual operation data registered in the individual operation database 111 with a similarity to a series of operations currently being performed. The scoring of the similarity is performed by a pattern matching method using past plant data stored in the plant measurement value database 150 and operation history data stored in the operation history database 160.

  The recommended operation selection unit 113 selects a recommended operation based on the similarity score by the operation procedure scoring unit 112. The operation selection result database 114 is a database that stores the scoring result of the similarity for each individual operation data by the operation procedure scoring unit 112, and the information of the type of individual operation and the selection result of the recommended operation by the recommended operation selection unit 113. is there.

  FIG. 2 is a diagram illustrating an example of individual operations registered in the individual operation database 111. Here, as a procedure for an individual operation, a flowchart type procedure diagram described in an operation manual or the like is illustrated.

  This individual operation includes the following steps S1 to S9. Step S1 indicates that a flag indicating that the measured value has reached a predetermined value in the device A is set. Step S2 indicates that a flag indicating that the measured value has reached a predetermined value in the device B is set. Step S3 is to confirm the measurement value of the device C. This step S3 is performed after satisfying the condition (AND condition) that both the flag of the measurement value A and the flag of the measurement value B are set.

  Step S4 is to operate the device D, and step S5 is to check the measured value of the device D. Step S6 is to perform operation of the device E, step S7 is to confirm the first measurement value of the device E (confirmation 1), and step S8 is to confirm the second measurement value of the device E. (Confirmation 2). Steps S4 and S6 are each performed after completion of step S3, but the order of implementation of both is arbitrary (including simultaneous). Step S5 is performed after step S4 is completed, and steps S7 and S8 are performed after step S6 is completed. However, the order in which steps S5, S7, and S8 are performed may be arbitrary. That is, the execution order of steps S4 and S5 related to the device D and steps S6 to S8 related to the device E may be arbitrary.

  Step S9 is to perform the operation of the device F. Step S9 is performed on condition that step S5 and at least one of steps S7 and S8 (OR condition) are both completed (AND condition).

  Thus, the individual operation content can be composed of information indicating the order of each step, information indicating the content of each step, and information on conditions for moving to the next step. In FIG. 2, the individual operations are illustrated in a flowchart format. However, the case where the individual operations are expressed in other formats such as sentences described in the operation manual can be considered in the same manner.

  FIG. 3 is a diagram showing an example of the contents of the individual operation data stored in the individual operation database 111, and shows the one corresponding to the individual operation of FIG. As shown in FIG. 3, the individual operation database 111 includes an operation content identifier D1 representing the specific content of each step of the individual operation, and sequence identifiers D2 and D4 and condition identifiers D3 and D5 associated with each. Stored.

  The order identifiers D2 and D4 indicate the order in which each step is performed. The order identifier of the present embodiment is assumed to have a two-layer data structure composed of a higher order identifier D2 and a lower order identifier D4. The condition identifiers D3 and D5 represent conditions for shifting from the corresponding plurality of steps to the next one or more steps. The condition identifier D3 is associated with the higher order identifier D2, and the condition identifier D5 is associated with the lower order identifier D4.

  The individual operations shown in FIG. 2 are stored in the individual operation database 111 as the following individual operation data using the identifiers D1 to D5. As shown in FIG. 3, the operation content identifiers D1 [S1] to D1 [S9] store information on the operation content in steps S1 to S9, respectively.

  In the higher order identifiers D2 [S1] to D2 [S9], information on the execution order of steps S1 to S9 is stored. Since the execution order of steps S1 and S2 performed first is arbitrary, the same order information “1” is stored in the upper order identifiers D2 [S1] and D1 [S2] corresponding to them. . Here, the condition for moving from step S1, S2 to the next step S3 is that the implementation of both steps S1, S2 is completed. Therefore, “AND” information is stored in the condition identifier D3 [S1-S2] associated across the higher order identifiers D2 [S1] and D2 [S2].

  Order information “2” is stored in the higher order identifier D2 [S3] corresponding to step S3 performed after steps S1 and S2. Steps S4 to S8 are performed after step S3. However, since the order of execution of steps S4 and S5 related to the device D and steps S6 to S8 related to the device E is arbitrary, step S4 and step S4 are performed. The same order information “3” is stored in both the upper order identifier D2 [S4-S5] associated across S5 and the upper order identifier D2 [S6-S8] associated across steps S6 to S8. Is done.

  However, since step S5 is performed after step S4, step S4 is associated with the lower order identifier D4 [S4] in which the order information “1” is stored, and step S5 is associated with the order information “2”. Is associated with the lower order identifier D4 [S5].

  Steps S7 and S8 are performed after step S6, and the order of steps S7 and S8 is arbitrary. Accordingly, the lower order identifier D4 [S6] in which the order information “1” is stored is associated with step S6, and the lower order identifier D4 [S7], in which the order information “2” is stored in both steps S7 and S8. D4 [S8] is associated with each other.

  Here, the condition for shifting from steps S4 to S8 to the last step S9 is that the execution of step S5 and the execution of at least one of steps S7 and S8 are both completed. Therefore, “OR” information is stored in the condition identifier D5 [S7-S8] associated across the lower order identifiers D4 [S7], D4 [8], and the higher order identifiers D2 [S4-S5], D2 are further stored. Information of “AND” is stored in the condition identifier D5 [S4-S8] associated across [S6-S8]. Further, the order information “4” is stored in the upper order identifier D2 [S9] corresponding to step S9.

  The operation procedure scoring unit 112 reads plant data stored in the plant measurement value database 150 and operation history data stored in the operation history database 160 together with time-series information, and a pattern matching method using these data Thus, the degree of similarity between the series of operations currently being performed and the individual operation data stored in the individual operation database 111 is scored.

  In this pattern matching scoring, recent plant data and operation history data (hereinafter referred to as “time-series data”) retroactive to a certain period (step) are compared with each individual operation data to determine the actual operation performed. A matching portion between the order and the operation procedure in the individual operation obtained from the individual operation data is searched, and each individual operation data is scored according to the length of the matching portion. The operation procedure of the individual operation registered in the individual operation database 111 is determined from the content of the operation content identifier D1 and the sequence identifiers D2 and D3 associated therewith.

  In the group of operation content identifiers D1 (for example, operation content identifiers D1 [S1] and D1 [S2] in FIG. 2) associated with the same “AND” condition identifiers D3 and D5 at the time of scoring, The order of D1 is not considered for scoring (the order is arbitrary). In the group of operation content identifiers D1 (for example, operation content identifiers D1 [S7] and D1 [S8] in FIG. 2) associated with the same “OR” condition identifiers D3 and D5, an operation that matches the actual operation is performed. The number of content identifiers D1 is not taken into account for scoring (at least one should match).

  The recommended operation selection unit 113 estimates which individual operation is currently performed based on the similarity of each individual operation data scored by the operation procedure scoring unit 112, and has already been performed in the individual operation. By distinguishing operations (steps) and unexecuted operations, an operation currently being performed is determined. Based on the result, an operation recommended to be performed next (recommended operation) is selected. When a plurality of individual operations with high similarity are found, the recommended operation selection unit 113 selects a plurality of candidates ranked in descending order of similarity as recommended operations to be performed next. The similarity between the individual operation data calculated by the operation procedure scoring unit 112 and the selection result by the recommended operation selection unit 113 are stored in the operation selection result database 114.

  Information on the current individual operation estimated by the recommended operation selection unit 113 and information on the selected recommended operation are accumulated in the operation selection result database 114 and are used for extraordinary work (for example, dealing with a plant accident or plant inspection). When necessary, or when there is a request from an operator, it is sent to the input / output control device 140. The input / output control device 140 can control the input / output device 180 to present operation guidance based on the information to the operator (a specific example of an information presentation method to the operator will be described later).

  In the present embodiment, an example is shown in which two layers of the higher order identifier D2 and the lower order identifier D4 are used as the order identifier for specifying the order of the operation content identifier D1, but the number of layers is arbitrary. Good. The individual operation shown in FIG. 2 can be specified using two layers, but the number of layers of necessary order identifiers differs depending on the content of the individual operation.

  In the supervisory control system according to the present embodiment, using the pattern matching method based on past plant data and operation history instead of the IF-THEN statement, the individual operation currently being performed and the recommended operation to be performed next are performed. Presumed. According to this method, the total number of necessary individual operation models corresponds to the number of corresponding operations defined in the operation manual or the like. This relationship does not depend on the assumed complexity of the operating procedure. For this reason, even when a complicated operation procedure is included or the operation order may be changed by the operator, an operation support system capable of appropriate guidance can be realized.

<Embodiment 2>
In the operation of a plant for extraordinary work such as recovery work in the event of a plant accident, there are cases where operation consisting of a large number of operation steps is performed for a long time. For example, in the monitoring control system according to the first embodiment, when an operation consisting of a large number of operation steps is treated as one individual operation and the individual operation data is to be registered in the individual operation database 111, the content of the individual operation data is very And the amount of data to be handled increases, making it difficult to create and manage individual operation data.

  When an operation having an enormous number of operation steps is defined, it is generally performed by dividing the operation into subsequences each composed of a relatively small number of operation steps. The second embodiment shows an example in which the management method using such a subsequence is applied to the monitoring control system according to the present invention.

  FIG. 4 is a block diagram of the monitoring control system according to the second embodiment. This supervisory control system can manage macro operations composed of combinations of one or more individual operations, and each individual operation is handled as a sub-sequence of macro operations.

  As shown in FIG. 4, the supervisory control system of the present embodiment has the same recommended operation selection device 110, central control device 120, plant measurement value collection device 130, input / output control device 140, and plant measurement value database as in the first embodiment. 150, an operation history database 160, and an input / output device 180, a macro operation management device 190 for determining the currently executed macro operation and its progress.

  The configuration of the recommended operation selection device 110 is the same as that in the first embodiment. However, the individual operation registered in the individual operation database 111 corresponds to each sub-sequence constituting the macro operation. The macro operation management device 190 has a function of registering operation procedure data in each sub-sequence of macro operation in the individual operation database 111 as individual operation data. The macro operation management apparatus 190 includes the following macro operation database 191, individual operation status determination unit 192, macro operation status determination unit 193, and macro operation determination result database 194.

  The macro operation database 191 is a database in which execution procedure data (macro operation data) of individual operations (subsequences) in each macro operation is stored. Since the macro operation is performed by sequentially performing a plurality of individual operations according to a predetermined condition, the relationship between the macro operation and the individual operation is the relationship between the individual operation and the operation step in the first embodiment. It is the same. Therefore, the macro operation data stored in the individual operation status determination unit 192 includes three types of identifiers: an identifier that represents the contents of each individual operation, an identifier that represents the order thereof, and an identifier that represents a condition for shifting to the next individual operation. (Depending on the contents of the macro operation, the identifier representing the order and the identifier representing the condition for shifting to the next individual operation may have two or more layers).

  The individual operation status determination unit 192 adds, to each individual operation, implementation status data indicating whether the status is unimplemented, being implemented, or implemented. The implementation status of each individual operation is determined based on the determination result by the recommended operation selection unit 113 of the recommended operation selection device 110 and its history (data accumulated in the operation selection result database 114).

  The macro operation status determination unit 193 determines the type of macro operation that is currently being executed and the degree of progress based on the execution status data (not yet executed / during / performed) of the individual operation. The determination results obtained by the individual operation status determination unit 192 and the macro operation status determination unit 193 are accumulated in the macro operation determination result database 194.

  FIG. 5 is a diagram illustrating an example of macro operations registered in the macro operation database 191 of the macro operation management apparatus 190. As an example of the macro operations, the individual operations P1 to P6 are defined to be performed in order. Macro operation M1 is shown.

  As shown in FIG. 5, the individual operations P1, P2,... Of the macro operation M1 correspond to the individual operations P1, P2,. However, in this example, the individual operation P3 of the macro operation M1 is defined as being completed when any one of the individual operations P3a to P3c registered in the individual operation database 111 is performed.

  Here, for the sake of simplicity of explanation, the macro operation M1 in which the individual operations P1 to P6 are simply performed in order is shown. However, for example, the execution order of the individual operations to be performed depending on conditions may be partially changed, The order of execution may be changed, for example, a plurality of individual operations may be performed simultaneously.

  The individual operation status determination means 192 is set to “Performed” when the recommended operation selection unit 113 of the recommended operation selection device 110 completes the execution of the individual operation data stored in the individual operation database 111 based on the determination result. "If a plurality of steps are being executed, implementation status data of" Not being executed "is added if only one step is being executed or if all steps are not being executed.

  In the example of FIG. 5, the individual operations P1 and P2 with hatching have been performed, the individual operation P3a with a thick frame is being performed, and the individual operations P3b and P3c and the individual operations P4 and thereafter are not performed. Indicates the state.

  The macro operation status determination unit 193 searches for a portion of the macro operation data stored in the macro operation database 191 that has been executed or being executed based on the execution status data added to each individual operation data. The longer that part is, the higher the degree of similarity with the current series of operations, and the more likely that the macro operation is currently being performed. Further, the progress of the macro operation can also be determined based on the implementation status data added to each individual operation.

  Information on the current macro operation and its progress determined by the individual operation status determination unit 192 and the macro operation status determination unit 193 is accumulated in the macro macro operation determination result database 194. Then, it is sent to the input / output control device 140 together with information on the current individual operation estimated by the recommended operation selecting unit 113 and information on the selected recommended operation according to a request from the operator or necessary. The input / output control device 140 can control the input / output device 180 to present operation guidance based on the information and information on the progress of the macro operation to the operator.

<Embodiment 3>
In the present embodiment, an example of a preferable aspect of the input / output device 180 in the monitoring control system according to the present invention is shown.

  FIG. 6 shows an example of a user interface provided in the input / output device 180 of the monitoring control system according to the present invention, and shows a configuration of a GUI (graphical user interface) displayed on the operation panel 40. The display panel 40 according to the present embodiment has a function of displaying various determination results, operation guidance, and the like by the monitoring control system according to the present invention together with a normal plant monitoring control screen.

  In FIG. 6, as an example of a normal plant monitoring control screen, a screen title display unit 41 that displays a screen title and a screen ID, a monitoring control screen display unit 43 that displays a plant measurement value and a software control switch, and a display screen A configuration including a menu display unit 44 provided with a selection button 441 for performing operations such as changing the screen and setting screens is shown.

  These display units do not necessarily have to be displayed independently of each other, and can be displayed in combination (for example, by arranging a selection button 441 in the screen title display unit 41, the screen title display unit 41 and the menu display unit are displayed. 44), a certain display unit may be further divided into other display units (for example, the menu display unit 44 is arranged inside the monitoring control screen display unit 43).

  The display panel 40 of the present embodiment displays an operation status display unit 42 for displaying various determination results, operation guidance, and the like by the monitoring control system on a part of the normal control screen as described above. Can do.

  In the operation status display unit 42, the individual operation registered in the individual operation database 111 is currently performed based on the information stored in the operation selection result database 114 (that is, the determination result by the recommended operation selection unit 113). One or more items are displayed in descending order of the estimated likelihood. The display method of the individual operation may be arbitrary, but for example, display in a flowchart method is conceivable.

  When there are a plurality of individual operation candidates having a high estimated likelihood, it is preferable that these can be switched and displayed. In FIG. 6, as a switching method, switching by an operation of a selection tab 421 that is a display symbol can be cited. In addition, a method using a pull-down menu or a list of names (IDs, etc.) of individual operations with high estimated likelihoods may be displayed on the screen.

  Further, when the estimated individual operations are displayed, the progress status (implementation state of each step) is classified and displayed for each step so that it can be identified. FIG. 6 also shows a display example of the progress status. In the flowchart displayed on the operation status display section 42, steps S1 to S3 and S6, which are shaded, have been performed, and steps S4 and S7 with thick frames are performed. In the middle, information indicating that other steps S5, S8, and S9 are not performed is displayed. The operator can determine an operation recommended to be performed next from the display of the progress status. In addition, as a method for displaying the progress status, other methods such as changing the display color and character format of each step can be considered.

  Furthermore, the display of the operation status display unit 42 may have a function as an input means for the operator to instruct the execution of the recommended operation. For example, the display symbol of the step corresponding to the recommended operation in the flowchart of the individual operation may be made to function as an interface for causing the monitoring control system to perform the recommended operation. Thus, the operator can easily perform the recommended operation.

  In the above description, the example of displaying the flow of the individual operation registered in the individual operation database 111 on the operation status display unit 42 has been shown. Of course, in the second embodiment, the flow is stored in the macro operation determination result database 194. Based on the information (that is, the determination result by the macro operation status determination unit 193), one or more macro operations registered in the macro operation database 191 are displayed in order from the one with the highest estimated likelihood that the macro operation is currently being performed. You may comprise.

  Also in this case, the display method of the individual operation may be arbitrary, but for example, display in a flowchart method is conceivable. In addition, when there are a plurality of macro operation candidates having a high estimated likelihood, it is preferable that they can be switched and displayed, and it is preferable that the progress status is also displayed together with the display of the macro operation.

  As described above, the individual operation and the recommended operation currently being performed or the macro operation currently being performed are illustrated on the display panel 40, so that it is possible to save the operator from checking the operation procedure from the operation manual. Can be reduced. This is effective for operations that require strict time constraints, such as operations that require urgency. In addition, since the status of operation, operation, and non-operation is displayed for each operation step (or for each individual operation) in an identifiable manner, procedure execution and progress can be easily confirmed, skipping steps and duplication It is possible to avoid an operation error caused by an operation or the like.
