BACKGROUND OF THE INVENTION
The present invention relates to a plant operation support system for supporting operation of a plant using a distributed control system in various plants such as a power plant, a waste treatment facility, and a chemical factory.
[0002]
[Prior art]
An operation control system using a computer is introduced for operation control of various plants such as a thermal power plant and a water purification plant. For example, taking a thermal power plant as an example, various plant configurations such as a fuel supply device that supplies fuel, a boiler that burns the fuel, and a power generator that rotates the turbine with steam converted by the boiler and converts it into electricity It consists of equipment. Further, in these various plant component devices, a large number of various process instruments for measuring the fuel supply amount, boiler combustion temperature, turbine rotation speed and cooling circulating water temperature are provided in each plant component device. Operation control of these plant components is usually performed by an operation control computer installed remotely from the plant site such as the central operation room, and the measured values measured by the plant instruments are provided in the central operation room. Centralized monitoring is performed by a control computer, and operation control of plant component equipment is performed as necessary, and warnings are issued to operators.
[0003]
The operation control of these plants is often so-called distributed processing, for example, monitoring control for each operation system in a large-scale plant. FIG. 42 is a schematic diagram of the distributed control system, and FIG. 43 is a schematic configuration diagram of the distributed control system 1. As described above, in the distributed control system, the plant component device 30 has an operation facility A, an operation facility B, and an operation facility C, for each function such as a fuel supply system, a boiler system, and a power generation system. Etc. and organized by system (each process). Further, in each operation facility, many process instruments 40 are provided in various plant component devices 30, and various measurement data measured by the process instrument 40 are operation control provided in each operation facility. Monitoring is performed by a monitoring device A, an operation control monitoring device B, and an operation control monitoring device C.
[0004]
Each of these operation control monitoring devices 10 includes a process data collection unit 11 that collects measurement data from each process instrument 40, and an alarm that determines an abnormality in the measurement data obtained from the process data collection unit 11 and generates an alarm. The data processing unit 12, the history data processing unit 13 that stores and retrieves history data such as past measurement data, the date and time of occurrence of the alarm, the location of occurrence of the abnormality, and the data that accompanies the data, and the history data are stored. Display of the abnormality detected by the history database 14 and the alarm data processing unit 12, display processing unit 15 for displaying and determining the current measurement data, display of data processed by the display processing unit 15, for example, display such as CRT Data transmission / reception unit for exchanging data with the device 16 and the operation control computer 20 and other operation control monitoring devices 10 7 is provided.
[0005]
Each of these operation control monitoring devices 10 is connected via an external interface 18 by a cable such as a LAN or wirelessly, and also connected to an operation management computer 20 installed in a central operation room.
[0006]
Further, the operation management computer 20 receives measurement data and alarm data from the operation control monitoring device 10 via the external interface 23, or transmits control data for controlling each plant component device 30 and A guide data calculation unit 21 that calculates control data from received measurement data and the like is provided.
[0007]
As described above, in a distributed monitoring system, a method of performing data management by collecting data for each process category to be monitored is generally used. Usually, the operation control monitoring device 10 monitors and measures the process behavior. The operation management computer 20 roughly divides the determination of whether or not the process can be executed during important process operation and the long-term management of operation data.
[0008]
In such a distributed control system, at the operation reference point (break point) of the driving operation of the driving control monitoring device 10 positioned at the lower level, the operating procedure manual prepared in advance by the operator or the same kind that has been performed in the past. After obtaining information such as driving operation method and setting value by the method of confirming the driving diary in which the driving records are summarized or the data parameters set in the driving control computer 20 located at the upper level A method of controlling the operation of the plant is employed. In addition, when an alarm occurs during operation, a method such as displaying the alarm occurrence status on the screen and notifying the operator is adopted, and a control system that considers reducing the load on the operator is also adopted. In some cases.
[0009]
[Problems to be solved by the invention]
Thus, in a normal operation state, the plant operator performs operation control of the plant based on the operation procedure manual prepared in advance. The operation procedure manual describes the operation procedure necessary for the monitoring operation of the plant, and is usually created by sorting according to the operation facility and operation process. More specifically, operation buttons and operation switches to be operated in each plant component 30, operation amounts, measurement data to be targeted at that time, and the like are described. The driving operation written in the driving procedure manual is performed while referring to it.
[0010]
These operating procedures are written in accordance with generally specified precautions and how the plant state changes after operation, that is, specific measurement data changes in transient response when a certain operation is performed. It is created empirically and added by accumulating driving. In addition, an actual operation screen, a hard copy of a trend graph, an operator's memo, and the like may be recorded in the operator's diary as plant operation know-how.
[0011]
However, in the case of a new plant or an initial operation stage, detailed and appropriate procedures are not sufficiently determined, and therefore, the operation procedure manual and operation diary are frequently referenced during the initial operation of the plant. The operation burden of plant operation becomes heavy. Furthermore, the burden on the operator due to complicated work such as review of the operation procedure manual and creation of operation records tends to be further increased.
[0012]
In addition, the operation procedure manuals and operation records created by the conventional method are printed on paper as books, and when referring to these, it is necessary to visually refer to the individual descriptions. . In this case, in order to extract the necessary data, there is a second problem in that the experience, ability, and organization method of the operator are increased and the usability is poor, and the effective utilization of the accumulated data becomes extremely difficult. It was.
[0013]
Thirdly, even during normal driving, the same driving operation is repeatedly performed when collecting measurement data of monitoring target items. When there are many items to be monitored, there is also a problem that the burden on the operator increases because it is necessary to keep an operation record for each operation even if only the measurement data is collected.
[0014]
Fourth, in the above-described distributed control system, the operation of the plant is often divided for each operating facility, and for example, materials are exchanged between the operating facilities such as the amount of fuel and cooling water. In this case, in response to a sending request from the sending side, information such as confirmation results of monitoring target items on the receiving side is usually not reflected on the sending side. For this reason, a series of driving operation confirmation items are divided and remain only as history data for each driving facility, and thus there is a problem that it is impossible to clearly grasp the trend between driving facilities during driving operation.
[0015]
Further, fifthly, the transient reaction data of the plant such as the change of the state with respect to the time transition of the monitoring target substance has conventionally recorded the trend graph as the graph data. In this case, when collecting transient reaction data of various substance states, an input display request corresponding to the driving operation is required every time the driving operation is performed, and there is a problem that smooth driving operation is hindered.
[0016]
Sixth, as described above, the recording of the transient reaction data of the plant by the trend graph, the data logger or the like is usually recorded in correspondence with, for example, the operation log in which the specific operation and the recording date / time are recorded. In order to confirm the operation of the plant during the reaction, it was first necessary to refer to an operation diary or the like. On the other hand, the recorded graph data often describes the operation method corresponding only to the graph data side as the file name and profile data, and it takes time and effort to find the necessary data. There is also a problem that it is difficult to search from.
[0017]
Next, as a seventh problem, when referring to driving performance data in the same driving operation performed previously, simply referring to the driving performance data at a specific point in time, the standard process behavior will be in any state. It is mentioned that it was unknown.
[0018]
Next, as an eighth, it is difficult to distinguish between data within the design allowable value range and data outside the range in correspondence with the alarm design value, and it is difficult to notice the modulation of the process behavior until an alarm or the like is issued. There was also a problem that perception was not intuitive.
[0019]
As a ninth problem, when the operator refers to image data such as a system screen or a tag window attached to the driving diary or a memo to call attention, etc., the screen diary from the driving diary etc. However, the screen data and the memo of the operator are stored separately from the operation procedure manual, and it is difficult to refer to them during the operation, and effective data cannot be used.
[0020]
Tenth, although the outline of the driving operation is written in the driving procedure manual, the driving diary etc. are detailed in detail until the action actually performed by the operator in response to the alarm occurrence event that occurred in the past. When a similar alarm occurs, the driving operation cannot be referred to immediately, the past experience cannot be used meaningfully, and the alarm cannot be promptly responded. There was also a problem.
[0021]
Furthermore, as an eleventh problem, detailed operation history information such as presence / absence of process operation and operation amount from the tag window does not remain, and detailed operation operation is reproduced. There was a problem that I could not.
[0022]
The present invention has been made in view of the above-described conventional problems, and facilitates the reference of various operation data and past various operation data corresponding to the operation procedure manual, thereby reducing the burden on the operator. It aims to provide a plant operation support system.
[0023]

In other words, the CRT display 152 has both an input device for obtaining a required operation information request and performing operation control, and an output device for outputting various output results necessary for operation control. .
[0059]
Next, the operation procedure of the process operation support system will be described in detail with reference to the flowchart of FIG. 5 in the case where past process data is displayed on the operation procedure manual display screen. First, an operation information request for performing a driving operation, specifically, a driving method to be obtained from now on, a past driving date and time, etc. (operation information request) are input. For example, from the CRT display 152 screen as the operation method (Note that the operation method input screen (not shown) is displayed by inputting the input unit 148 that is closed from the operation procedure manual display screen shown in FIG. 2). , “Transfer solution from storage tank to □□ storage tank” is selected, the operation date / time to be obtained is input as required, and the change execution input field 145 is touched to display the procedure manual (step S101). . The information request input unit 140 outputs “driving method” and “driving date and time” to the history data processing unit 120 as the operation information request (search key) (step S102). In addition, the information request input unit 140 outputs only the information necessary for obtaining the procedure manual data, that is, the “driving method” in the operation information request from the data transmitting / receiving unit 101 to the procedure manual data processing unit 320 ( S103).
[0060]
Next, the history data processing unit 120 accesses the history database 110 using the output operation information request, that is, “driving method” and “driving date and time” as search keys, retrieves the corresponding process data, and operates the process data. It outputs to the display process part 152 with a tag (S104). On the other hand, the procedure manual data processing unit 320 accesses the procedure manual database 310 using the transmitted operation information request, that is, “operation method” as a search key, searches for the corresponding procedure manual data, and stores the procedure manual data together with the operation tag. It outputs to the procedure manual preparation part 130 (S105). Subsequently, the procedure manual creation unit 130 converts it into procedure manual display data in accordance with the output procedure manual data, and then outputs it to the display processing unit 152 together with the operation tag (S106).
[0061]
The display processing unit 152 combines the history data and the procedure manual display data on condition that the operation tags match (S107), converts the history data into the display signal that can be displayed on the screen of the CRT display 152, and the CRT display 152. The past process data to be referred to together with the operation procedure manual is displayed on the data display column 154 on the CRT display 152 screen (S108).
[0062]
As described above, the operator instructs the operation information request to be operated from the CRT display 152, and the necessary operation procedure manual is immediately displayed on the CRT display 152. At this time, it is also possible to know past process data as a reference. As a result, it is not necessary to examine the history data by hand-turning as in the prior art, and it is possible to perform an appropriate driving operation, and it is possible to easily predict and confirm the behavior of the process component equipment due to the driving operation.
[0063]
In the above embodiment, the case where instantaneous data is recorded as process data has been described. However, the process data can also be applied to a case where continuous time series data is recorded. it can.
[0064]
  Plant operation support system shown in FIG.Is the firstThis relates to the second embodiment. In this plant operation support system, process data is recorded in time series in the history database 110, and the process data during the operation can be displayed as a graph on the operation procedure manual display screen. This is different from the first embodiment.
[0065]
That is, as shown in FIG. 7, the history database 110 is provided with a collection period field in which the sampling period of the process data is recorded and a collection period field in which the sampling period is recorded in the history database 110 shown in FIG. In the process data field, process data collected at the sampling period recorded in the collection period field is continuously recorded.
[0066]
Further, when the history data processing unit 120 retrieves the designated history data, the history data processing unit 120 outputs the operation history data related to the sampling period and the sampling period together with the process data (graph data) to the display unit 150.
[0067]
The display processing unit 152 displays the operation procedure manual on the CRT display 152 and, based on the instruction from the operation information request input unit 140, the elapsed time on the horizontal axis based on the output sampling period and sampling period. The process amount is displayed on the vertical axis, and the graph is displayed on the screen. At this time, the occurrence date and time is recorded in the history data, and the operation record is associated with the occurrence date and time, and a graph is displayed on the screen.
[0068]
More specifically, in the plant operation support system, when an operation procedure document display request is made, an operation procedure document display screen similar to that shown in FIG. 2 is displayed as shown in the upper part of FIG. However, for example, the data display field 154 corresponding to the operation tag in step 2 also has an assignment processing request input field 147. In the assignment process input field 147, an input request such as “graph display” is displayed. By touching the assignment processing request input field 147, the operation procedure manual display screen is switched, and process behavior data (graph) as shown in FIG. 8 is displayed.
[0069]
Furthermore, when this plant operation support system is described according to the flowchart shown in FIG. 9, when a graph display is selected from the operation procedure manual display screen (S201), the history data processing unit 120 is based on the instructed allocation process request. The history database 110 is searched, and the corresponding history data is output to the display unit 150 (S202). The display unit 150 assigns the operation history and operation time based on the history data (S203), and displays the graph on the CRT display 152 (S204).
[0070]
In this way, it is possible to handle the process data as time series data, and a series of operation operations and changes in the process data can be tracked in time series, so that the operation control of the plant can be performed more reliably.
[0071]
  Next, the plant operation support system shown in FIG. 10 will be described. The plant operation support systemIs the firstThis relates to the third embodiment. This plant operation support system differs from the plant operation support system in the first embodiment shown in FIG. 1 in that a process data collection unit 160 and a process data processing unit 170 that records process data in the history database 110 are provided. . That is, in the plant operation support system, in addition to displaying the operation procedure manual, the process data of the plant component device 30 obtained according to the called operation procedure manual is recorded in the history database 110 and the history database 110 is to be updated. Is.
[0072]
The process data collection unit 160 collects each measurement data from the process meter 40 installed in each process component device 30 via the external interface 102 as shown in FIG. This is exactly the same as the process collection unit 11.
[0073]
Based on the operation information request input from the information request input unit 140 during the display of the operation procedure manual, the process data processing unit 170 displays the operation procedure manual that has displayed the process data from the process data collection unit 160. As shown in FIG. 10, based on the operation processing request input from the allocation processing database 171 and the information request input unit 140, as shown in FIG. , An allocation process creation unit 172 that identifies process data to be collected, that is, a process component device 30 to be collected, and an allocation process execution unit 173 that executes the allocation process obtained by the allocation process creation unit 172. .
[0074]
The allocation process in this plant operation support system is an allocation process provided corresponding to each operation tag on the operation information request input unit 140, specifically, on the leftmost side of the operation procedure manual display screen during the operation procedure manual display. By instructing the allocation process from the input field 145 and touching the allocation process change execution input field 143, the allocation process is started, and the allocation process request, that is, the operation procedure and process data stored in the history database 110 as history data And the operation procedure and process data actually performed are stored.
[0075]
That is, in the process operation support system, as shown in FIG. 11, on the CRT display 152, for example, as an XX facility XX process, an operation procedure manual for solution transfer operation from △△ storage tank to □□ storage tank However, step 1, step 2, step 3,... Are sequentially displayed as follows. While the operation procedure manual is displayed, the allocation processing execution display is displayed as a check box for each step. The input field 144 is displayed in a selectable manner. Next, after selecting the allocation process, when the allocation process is executed from the change execution input field 145, the type of operation and process data to be stored as history data is specified and executed according to the selected allocation process. Is done.
[0076]
For this reason, as shown in FIG. 12, the procedure manual database 310 of the process operation support system is provided with a related assignment process number field, and this field serves as a search key for executing the assignment process. A related assignment process number is assigned for each operation tag. Further, as shown in FIG. 13, the allocation processing database 171 records a related interrupt processing number field, an execution order field in which an execution order number is recorded, an operation tag field in which an operation tag name is recorded, and a content to be processed. A content field is provided.
[0077]
The related allocation process number is the same as the related process number recorded in the procedure manual data database 310, and is assigned to each operation tag displayed as the operation procedure manual. The execution order number defines the order of execution when there are a plurality of operation operations and process data to be stored. Further, the operation tag is required to be combined with the procedure manual information when it is searched again after being stored in the history database 110, and is the same as that recorded in the procedure manual database 310. The operation tag is recorded. Specific processing content is recorded in the processing content field. For example, as shown in FIG. 11, “effective flow number storage” processing is recorded in the effective processing number (No) 1 as the processing content, and the allocation processing execution unit 173 performs the process specified by the process data collection unit 160. After obtaining the flow rate value of the device 40, the history data processing unit 120 is instructed to save the flow rate value in the history database 110.
[0078]
Next, the operation procedure in this process driving support system will be described based on the flowchart shown in FIG. In the process operation support system, the necessary operation procedure manual is displayed in the same manner as the process operation support system according to the first embodiment, and the description thereof is omitted here. The operation procedure manual will be described from the displayed stage.
[0079]
When a required operation method is selected from the information request input unit 140, an operation procedure manual is displayed on the CRT display 152 screen as shown in the upper part of FIG. Is displayed. From this state, the requested allocation process request input field 144 is selected and the execution change input field 145 is touched to execute the allocation process (S301). When the allocation processing is executed, the allocation processing unit searches the allocation processing database, searches for necessary processing, and extracts processing contents (S302). Next, if the operator touches the confirmation display field 143 and confirms that the operation indicated in the operation procedure manual has been performed, the assignment process is executed (S303), and the process data collection unit 160 instructs The processed process data is collected (S304). The process data is stored in the history database 110 by the history data processing unit 120 together with necessary items such as the date and time of occurrence (S305).
[0080]
In this way, the operation procedure manual can be displayed, and the operation history data operated according to the displayed operation procedure manual and the process data as a result can be stored. As a result, it is possible to save the operation history and the behavior of the plant component device 30 that is operation-controlled, and it is possible to easily store and retrieve the material in the subsequent operation examination.
[0081]
  Next, the plant operation support system shown in FIG. 15 will be described. This plant operation support systemThe second4 embodiments. Although this plant operation support system is different from the third embodiment in that it collects process data continuously, the system configuration is completely the same. That is, in the present plant operation support system, the process data is continuously measured to be stored as time series data.
[0082]
The history database 110 in the plant operation support system has a structure similar to that of the history database 110 according to the second embodiment (see FIG. 7), and in order to store process data in time series, a collection period A field and a collection period field are provided. In addition to the allocation processing database of FIG. 13, the allocation processing database 171 also includes a collection period field for recording the sampling period of process data for each related allocation number and a collection period field for recording the sampling period as shown in FIG. Is provided.
[0083]
In this plant operation support system, as shown in FIG. 17, the system is substantially the same as the plant operation support system according to the third embodiment, but in the plant operation support system, data sampling for a certain period is performed. Therefore, the process data collection unit 160 includes an off timer as shown in FIG. 17, and the allocation processing unit sets the sampling period and sampling period extracted from the allocation database to the off timer.
[0084]
The operation procedure in the plant operation support system will be described with reference to the flowchart of FIG. 18. First, when the required operation method is selected from the information request input unit 140, the operation is performed on the CRT display 152 screen as shown in the upper part of FIG. 17. A procedure manual is displayed, and an allocation processing request input field 147 is displayed on the right side of the screen simultaneously with the operation procedure manual. From this state, the allocation process is selected and the change execution input field 145 is touched to execute the allocation process (S401). The assignment process input field 145 is displayed in the data display field 154 as shown in FIG. When the allocation process is executed, the allocation process execution unit 173 searches the allocation process database 171 and extracts a sampling period and a sampling period together with necessary processes (S402). Next, if the operator confirms that the operation shown in the operation procedure manual has been made by touching the confirmation display field 143, the allocation process is executed (S403). The sampling period and sampling period are set to the off timer (S404). Thereafter, the process data collection unit 160 collects the instructed process data (S405). The process data is stored in the history database 110 by the history data processing unit 120 together with necessary items such as the date and time of occurrence (S406).
[0085]
  According to this plant operation support system, process data can be continuously recorded, and operation management can be easily performed. Further, after the recording, the plant operation support system shown in FIG. 19 will be described next, as in the second embodiment, it becomes possible to search for a continuous change due to the operation operation. The plant operation support system isThe second5 embodiments. In addition to the configuration of the plant operation support system according to the second embodiment shown in the figure, based on the operation information request input from the information request input unit 140 during the display of the operation procedure manual, the history database 110 A process data calculation unit 180 that calculates an average value and a deviation value of the recorded process data is provided, and the calculated average value and deviation value can be displayed as a graph. That is, the plant operation support system is for referring to what kind of process data is obtained when the same operation operation is performed. This makes it easy to judge the validity of
Next, the plant operation support system shown in FIG. 22 will be described. The plant operation support system isThe second6 is different from the third and fourth embodiments in that it further includes a process data determination unit 190 that determines abnormality of the process data collected by the process data collection unit 160. Is. That is, when the process data obtained during or after the driving operation is abnormal, the abnormality is automatically determined and an alarm is transmitted to the operator.
[0086]
As described above, the process data calculation unit 180 shows the behavior of each plant component device 30 when a designated assignment processing request (operation information request), that is, a specific selected operation is performed. In other words, the average value and the deviation value of the obtained process data are calculated. Accordingly, the history database 110 in the plant operation support system has a structure as shown in FIG. 4 or FIG. 7, for example, and either an instantaneous value or a continuous value (graph data) is used for the process data field. .
[0087]
In the plant operation support system, as shown in FIG. 20, the display of the allocation process request input field 147 is selectably displayed for each operation tag while the operation procedure manual is displayed. At this time, the assignment processing request input field 147 is displayed in the data display field 154 as shown in FIG. Next, when the necessary allocation process request input field 147 is selected and the change execution input field 145 is touched to execute the allocation process, the process data calculation unit 180 operates as the allocation process request selected by the history data processing unit 120. Send tag.
[0088]
The history data processing unit 120 searches the process data field using the selected operation tag as a search key, and outputs all of a series of process data operated under the same operation condition to the process data calculation unit 180. The process data calculation unit 180 calculates the average value and the deviation value of the process data from the output process data and outputs them to the display unit 150 in time series. The display processing unit 152 generates the calculation results based on these calculation results. And a graph is displayed on the CRT display 152. At this time, if the process data is instantaneous time data, it is displayed as a time series according to the operation date and time when the driving operation was performed. If the process data is time series data, the average value and deviation value of each time series data are displayed. Is done.
[0089]
Further, the process data calculation unit 180 of the plant operation support system calculates a standard behavior using the average value and the deviation value, and determines whether the past history data is standard. The history data determined to deviate from the standard behavior is deleted by the history data processing unit 120.
[0090]
The operation of the plant operation support system will be further described with reference to the flowchart of FIG. 21. First, an operation procedure manual to be displayed is designated from the CRT display 152 screen by designating an operation method (S501). According to the display request, FIG.
An operation procedure manual as shown is displayed, and an assignment process request input field 147 for obtaining an average value and a deviation value is displayed in the data display field 154 corresponding to each operation tag. When the operator touches the assignment processing request input field 147 to select an operation tag for obtaining an average value and the like, and the execution of the assignment process is instructed from the change execution input field 145 (S502), the process data calculation unit 180 displays the history. All the process data matching the operation tag is requested from the data processing unit 120, and the history data processing unit 120 extracts all the process data and outputs it to the process data calculation unit 180 (S503). Thereafter, the process data calculation unit 180 calculates an average value and a deviation value from the output process data and outputs them to the display unit 150 (S504), and the display unit 150 displays the calculated average value and deviation value on the occurrence date and time. Is displayed as a graph with the horizontal axis (S505). Further, the process data calculation unit 180 selects data that is recognized as deviating from the standard behavior, for example, process data that is outside the 95% confidence limit range, based on the average value and the deviation value. The history data corresponding to the data is determined to be abnormal, and the history data processing unit 120 deletes the history data (S506).
[0091]
Thus, in the said plant operation assistance system, it can graph on the basis of the recorded historical data, and can determine the result of driving operation more reliably. In particular, as in the third and fourth embodiments, unnecessary history data is sequentially applied by applying it to a plant operation support system that automatically captures process data from process equipment during operation. As a result, the plant operation with higher accuracy can be performed.
[0092]
  Next, the plant operation support system shown in FIG. 22 will be described. The plant operation support system isThe second6 is different from the third and fourth embodiments in that it further includes a process data determination unit 190 that determines abnormality of the process data collected by the process data collection unit 160. Is. That is, when the process data obtained during or after the driving operation is abnormal, the abnormality is automatically determined and an alarm is transmitted to the operator.
[0093]
The process data processing unit 170 in the plant operation support system is the same as the process data processing unit 170 shown in FIG. 10 or FIG. 15, and the process data determination unit 190 includes an operation allowable value database 191.
[0094]
As shown in FIG. 23, the operation allowable value database 191 records the maximum allowable value and the minimum allowable value of the process data within the normal range for each operation tag, that is, for each operation operation. The process instrument 40 to be determined is determined by the process data processing unit 170, the process instrument 40 to be monitored is determined for each operation tag, and the normal range value is also determined for each process instrument 40. It has been. Furthermore, when the operation control monitoring unit 10 is provided with an alarm data processing unit, the normal range value can be set to a value different from the alarm determination value.
[0095]
In the plant operation support system, as shown in the upper part of FIG. 24, the assignment process is instructed from the assignment process request input field 147 provided corresponding to each operation tag on the operation procedure manual display screen, and the change execution is performed. By touching the input field 145, the allocation process is started, and process data set in the allocation process database 171 in advance is collected. The process data collected at the same time is displayed in the data display field 154. Further, the data display field 154 also has an allocation process request input field 147, and touching the allocation process request input field 147 allows the process data processing unit 170 to determine data abnormality. Thus, when it is determined that the collected process data is abnormal, as shown in the lower part of FIG. 24, the collected data is displayed, for example, in green if it is within the normal range value, and is outside the normal range value. For example, it is displayed in red. Of course, it is needless to say that determination of data may be performed only by instructing the allocation process from the allocation process request input field 147 provided corresponding to each operation tag.
[0096]
Next, the operation procedure in this plant operation support system will be described with reference to the flowchart of FIG. 25. First, when a process data abnormality determination request is made from the assignment process request input field 147 on the operation procedure manual display screen (S601), the process The process data in the process meter 40 determined from the data collection unit 160 is displayed in the process data display field (S602), and the data is output to the process data determination unit 190. The process data determination unit 190 searches the allowable operation range, that is, the minimum allowable value and the maximum allowable value from the allowable operation value database 191 using the operation tag as a search key, and determines the allowable operation range and the collected process data. In comparison (S603), if it is within the normal range, the display unit 150 sets the process data to, for example, green, and if it is outside the normal range, the display unit 150 sets the process data to, for example, red, in the process data display column. indicate.
[0097]
As described above, by providing the process data determination unit 190, abnormality of the process data obtained as a result of the operation operation is immediately determined, and the plant operation can be performed more reliably.
[0098]
  Next, the plant operation support system shown in FIG. 26 will be described. The plant operation support system isThe secondThe plant operation support unit includes an inter-facility information database 201 in which operation information requests between other facilities related to the operation method are recorded corresponding to each operation method. Based on the inter-facility operation information request input from the information request input unit 140, reference is made to the history data recorded in the history database 110 of the other plant operation support unit 100 recorded in the inter-facility information database 201. The other facility operation history processing unit 200 that displays the history data in the other facility on the history database 110 and / or the display unit 150 is provided.
[0099]
In other words, in the present embodiment, when a substance is exchanged with another facility, the substance can be traced. After obtaining the history data operated by the plant operation support unit 100 provided, the history data is displayed on the operation procedure manual display screen and, if necessary, recorded in its own history database 110. To do.
[0100]
As shown in FIG. 27, the inter-facility information database 201 is provided for each plant operation support system, and the inter-facility information database 201 includes the operation method for each operation method of each plant component device 30. Other operating methods related to the material handled are recorded. For example, the inter-facility information database 201 is provided in the plant operation support unit 100 of the facility 1, and the plant operation support unit 100 related to the common transfer substance with respect to the operation method A in the own facility is as follows. The plant operation support unit 100 of the facility 3 indicates the operation method α. For operation method B, the operation method b in the plant operation support unit 100 of the facility 2 is shown. Furthermore, for the operation method C, the operation method a in the plant operation support unit 100 in the facility 4 is shown.
[0101]
Similarly, the inter-facility information database 201 shown in FIG. 28 is the inter-facility information database 201 in the facility 2, and there is no plant operation support unit 100 corresponding to the own facility operation method a, and the operation method b. Indicates that the operation method B corresponds to the plant operation support unit 100 in the facility 1, and that the operation method c corresponds to the plant operation support unit 100 in the facility 3 and the operation method γ. Similarly, the plant operation support unit 100 in the facility 3 and the plant operation support unit 100 in the facility 4 are also provided with a similar inter-facility information database 201. In the illustrated example, the operation method of another facility related to one operation method corresponds to only one operation method, but in the one plant operation support unit 100 corresponding to one operation method, 2 There may be a case where two or more operation methods in the plant operation support unit 100 correspond to the above operation method or one operation method.
[0102]
In addition, the other facility operation history processing unit 200 receives the operation information request input from the information request input unit 140, here, the operation method in the other facility from the inter-facility information database 201 using “operation method” as a search key, That is, the operation information between other facilities is retrieved and output to the other facility operation history processing unit 200 in the other related plant operation support unit 100.
[0103]
Further, the other facility operation history processing unit 200 uses the search information necessary based on the inter-facility operation information request output from the other other facility operation history processing unit 200, here “driving method” as a search key. The history data output to the data processing unit 120 and the history data output from the history data processing unit 120 are output to the other facility operation history processing unit 200 requested to output through the external interface 102. Therefore, the history data processing unit 120 in the plant operation support system needs to have a function of outputting only history data, particularly process data, from the output search information and outputting it to the other facility operation history processing unit 200. There is.
[0104]
The operation procedure of the plant operation support system including the other facility operation history processing unit 200 will be described with reference to the flowchart shown in FIG. 29. In addition to the “operation method” and “operation date and time”, other operation control When an operation information request between the monitoring devices 10 is input from the information request input unit 140 (S701), the history data processing unit 120 corresponds to the own facility history database 110 in response to the operation information request. History data is extracted (S702). On the other hand, the other facility operation history processing unit 200 searches and extracts the operation method and the facility name in the other facility for the operation method specified from the own inter-facility information database 201, and extracts other corresponding plant operation support units 100. “Driving method” is output as a search key to the facility operation history processing unit 200 (S703).
[0105]
The other facility operation history processing unit 200 of the other plant operation support unit 100 outputs the search key “operation method” to the history data processing unit 120 and records the date and time of the access (S704). Incidentally, when this recording is performed, a related operation is performed, so that the operation operation performed is recorded in the operation operation history of the plant operation support unit 100.
[0106]
When the other facility operation history processing unit 200 requests the other facility operation history processing unit 200 to transmit the corresponding history data (S705), the other facility history data processing unit 120 outputs the above-mentioned data. The history data is searched based on the retrieved key, and the corresponding history data, particularly professional city data, is extracted (S706) and output to the other facility operation history processing unit 200 (S707).
[0107]
In addition, the other facility operation history processing unit 200 in the plant operation support unit 100 to which the operation information request is input transmits the history data output from the other facility to the history data processing unit 120, and uses the operation date and time as a combination key. The history data of the own facility and the history data of the other facility are combined (S708) and recorded in the history database 110 (S709). The combined history data (process data) is displayed on the operation procedure screen (S710).
[0108]
As described above, in the plant operation support system, when the material exchange is performed across the plurality of operation control monitoring units 10, the change in the material exchange is performed in the operation control monitoring apparatus that has performed the operation. Can be observed. In addition, this plant operation support system can be applied not only to the exchange between the operation monitoring units 10 but also to the case of a divided management system performed using a plurality of operation management computers.
[0109]
  Next, the plant operation support system shown in FIG. 30 will be described. The plant operation support system isThe secondIn this embodiment, the image data is recorded as history data. That is, the plant operation support system has substantially the same system configuration as the plant operation support system of the first embodiment shown in FIG. 1, but an image database in which image data (screen information) corresponding to each operation method is recorded. 210 in that the image data processing unit 220 displays and records the image data based on an operation information request input from the image data processing unit 220 during the display of the driving procedure.
[0110]
FIG. 30 shows the structure of the image database 210. The image database 210 includes a driving operation item field, a storage date / time field for recording the storage date / time, a driving method field indicating a driving method name, and an image data type. An image data type number field in which a number is recorded and an image data field in which image data is recorded are provided.
[0111]
In the driving operation item field, an operation information request input from the driving procedure manual display screen, for example, as shown in FIG. 32, a name corresponding to an image acquisition input field (screen name) called from the image data acquisition screen is recorded. Is done. The save date / time field indicates the date / time when the image data was saved. The driving method field stores a driving method serving as a search key, and the image data type number is a number assigned to each type of recorded image data. In the image data field, image data actually recorded by the input operation information request is stored.
[0112]
The image data processing unit 220 is activated based on the operation information request input from the information request input unit 140, and the image data processing unit 220 is based on the operation information request input from the history database 110. The necessary image data is output to the display unit 150, and the image data is displayed on the CRT display 152. Further, the image data processing unit 220 receives the operation information request input from the information request input unit 140 (for example, a screen recording request input field (not shown) is displayed by touching the assignment process change input field 143 shown in FIG. 2). The history database 110 is recorded in the image database 210 together with the operation method name corresponding to the displayed operation procedure manual data.
[0113]
Further, for example, in detail with reference to FIG. 32, when image data selection is input as an operation information request from the operation procedure manual display screen, the image data processing unit 220 displays an image data acquisition screen as shown in FIG. To do. On the image data acquisition screen, the types of image data to be obtained include, for example, an entire screen display (Screen), a pop-up screen display (Pop-up), and an operation tag screen display (tag). The image data acquisition screen is displayed on the display screen as needed. For example, the image data acquisition screen can be selected even when a graph data screen as shown in FIG. 33 is displayed.
[0114]
For example, as shown in FIG. 34, the entire image data is a screen showing an overall system diagram of the operation control monitoring device 20 corresponding to the plant operation support unit 100, and the pop-up screen is necessary only for the operation method. The operation tag screen is a screen showing a driving operation method necessary for the selected driving method. Of course, the displayable image data is not limited to these screens, and image data required for driving operation is selected. Further, for example, when the entire image data is selected, the image data processing unit 220 may be presented with more detailed screen acquisition information and requested to input the allocation operation information.
[0115]
Next, the operation procedure in the plant operation support system will be described with reference to the flowchart shown in FIG. 35. First, when an image data display request is made from the operation procedure manual display screen, an image data acquisition screen is displayed on the CRT display 152. Then, an operation information request is input (S801). Next, the image data processing unit 220 determines whether or not the operation information request input from the detailed image data acquisition screen is “new creation” (S802). It is acquired from the display unit 150 (S803), and recorded in the image database 210 together with necessary items such as the storage date and time and the image data type number (S804). On the other hand, if it is not “new creation” in S802, the image data processing unit 220 retrieves and extracts the corresponding image data from the image database 210, outputs the image data to the display unit 150, and displays the image on the CRT display 152. Data is displayed (S805).
[0116]
As described above, in the plant operation support system, image data can be saved if necessary, and necessary past image data can be displayed from the displayed operation procedure manual. Yes.
[0117]
  Next, the plant operation support system shown in FIG. 36 will be described. The plant operation support system isThe secondThe present invention relates to a ninth embodiment, and is applied to a distributed control system including an alarm data processing unit 12. hereWearThe history database 110 further includes an alarm data type field in which alarm information is recorded, and the plant operation support unit 100 records history data recorded in the history database 110 based on the alarm information output from the alarm data processing unit 12. Is provided with an alarm processing unit 230 that outputs the. That is, this plant operation support system is intended to display the operation history information at that time together with the operation procedure manual on the CRT display 152 in response to the same alarm that has occurred in the past.
[0118]
The alarm data processing unit 12 is provided for each operation control monitor 10 and when the measured measurement data exceeds a set alarm limit value, the process instrument 40 that detected the alarm and the signal name The degree of the alarm, that is, the level of importance of the alarm, for example, whether it is a heavy alarm, a medium alarm, or a light alarm is determined. The information is output to the intelligence processing unit 230.
[0119]
When the alarm processing unit 230 detects the intelligence information determined by the alarm data processing unit 12, that is, the facility or process that detected the alarm, the alarm processing unit 230 outputs the alarm information to the history data processing unit 120, Corresponding history data is searched from the history database 110 based on the facility / process information from the history data processing unit 120. As shown in FIG. 37, the history database 110 in the plant operation support system records a storage date / time field for recording the date and time when the alarm occurred, an alarm data type field for recording the degree of the alarm, and the facility / process where the alarm occurred. A facility / process field, an operation method field indicating a target operation method, an operation tag field, a record data field for recording the specific contents generated, and a process data field for recording process data at that time. Further, in the recording data field, what kind of process instrument 40 has generated an alarm and what kind of symptom has occurred is specifically recorded.
[0120]
The operation procedure in the plant operation support system will be described with reference to the flowchart of FIG. 38. When alarm data processing unit 12 force information is detected during normal operation, alarm information is output to the alarm processing unit 230 (S901). The alarm processing unit 230 searches the alarm information for the process instrument 40 and the signal name as a search key, and outputs them to the history data processing unit 120 (S902). The history data processing unit 120 searches the history database 110 using the searched search key, and outputs the hit history data to the alarm processing unit 230 (S903). At this time, the history data processing unit 120 outputs a series of operations when an alarm is generated as a block unit from the alarm generation to the return time. The alarm processing unit 230 rearranges the hit history data, for example, for each driving process or rearranges them in time series, outputs them to the display unit 150, and displays them on the CRT display 152 (S904).
[0121]
As described above, in the plant operation support system, when an alarm is generated in synchronization with an alarm from the operation monitoring control system, history data at the time of occurrence of the past alarm is displayed, and past history data at the time of occurrence of the alarm is displayed. Can be easily confirmed.
[0122]
  Next, as shown in FIG.SecondA plant operation support system according to ten embodiments will be described. In each of the above plant operation support systems, it was possible to display an operation procedure manual, display conventional history operation information, or obtain plant data by operation operation. The operating procedure could not be recorded. For this reason, for example, when an abnormality occurs, the plant operator cannot reproduce what procedure the information was obtained from the plant operation support system. In addition, if the operation procedure at that time was not the most effective one, it was necessary to learn a new procedure through subsequent trial and error. Therefore, in the plant operation support system, the operation procedure in each of the plant support systems can be recorded explicitly. In the plant operation support system, a process data collection unit 160 that collects process data from the process meter 40 is provided.
[0123]
The plant operation support system includes an operation record processing unit that records an operation procedure actually operated based on an operation procedure document based on an allocation process request input from the image data processing unit 220 while the operation procedure document is displayed. 240 is provided. The operation record processing unit 240 includes an operation record creation unit 241 and an operation record database 242.
[0124]
The operation record database 242 has, for example, the same structure as the assignment process database 171 shown in FIG. 13, an associated assignment process number field indicating an assignment process number, an execution order data field in which a series of operation orders are recorded, an operation An operation tag field indicating a tag and a processing content data field for recording specific processing content are provided. Therefore, when the operation record database 242 includes an assignment processing database 171 corresponding to the claims, the operation record database 242 can also be used as the operation record database 242.
[0125]
When the operation record creation unit 241 selects an operation information request (assignment process creation) input from the control / monitoring screen, for example, the operation tag field is selected from the monitoring screen shown in the upper part of FIG. 40, the assignment process is executed. An allocation processing screen as shown in the middle part of FIG. 40 is displayed. Next, when operation tag information is selected from the assignment processing screen and change execution is input, process data is collected and the operation record is recorded in the operation record database 242.
[0126]
Next, the operation procedure in the plant operation support system will be described based on the flowchart shown in FIG. First, as shown in FIG. 40, an operation tag is selected from the control operation procedure manual display screen and the assignment process change execution is performed (S1001), and the assignment process screen is displayed. Next, an operation tag to be recorded as an allocation processing operation information request is designated, and an operation for actually performing the operation is set (S1002). Thus, when an actual tag operation (driving operation) is performed (S1003), process data is collected by the process collection unit 160 (S1004), and the operation record creation unit 241 operates an operation procedure to be actually performed together with the operation tag. The execution order is sequentially written in the execution order data field, and the process data is recorded in the history database 110 (S1005). In this way, the actual operation is recorded on the operation record database 242. By providing the operation record processing unit 240 in this way, the contents actually operated are appropriately recorded, and the optimum operation can be easily reproduced. These operation records are recorded in the operation record database 242, but may be recorded on the history database 110 as a matter of course.
[0127]
In the present invention, data of the process instrument 40 provided in the plant component device 30 is collected as process data. However, not only the measurement value from the process instrument 40 but also the periphery of the plant component device 30 is photographed. A camera such as a CCR can be used, and the present invention can also be applied to image data at that moment and moving image data recorded for a certain period of time.
[0128]
【The invention's effect】
  According to the invention of claim 1 of the present application,The average value and deviation value of the accumulated process data can be displayed as a graph. As a result, the trend of the plant component equipment to be operated from now on can be easily obtained as a graph. Moreover, it can be easily extracted from the operation procedure manual without complicated operations.
[0129]
  According to the invention of claim 2 of the present application,According to the alarm information transmitted from the alarm data processing unit that detects an alarm, it is possible to easily refer to history data at the time of a similar alarm that has occurred in the past. Therefore, the operator can immediately perform the same driving operation even when the alarm is generated, and can use the past experience meaningfully.
