2. Description of the Related Art FIG.
FIG. 1 is a diagram illustrating a system configuration of an operation device, a so-called touch operation device, in a conventional plant operation system disclosed in Japanese Patent No. In this figure, reference numeral 1 denotes a plant to be operated, for example, a control device 1a, a drive circuit 1b, a process control device 1c, and various detectors 1d.
And so on. Reference numeral 2 denotes a process input / output processing unit that captures a plant process amount from each unit of the plant 1 and gives an operation instruction to the plant 1. 3 denotes an operation screen on a CRT (screen display device) 5 based on data from the process input / output processing unit 2. , A display screen control unit 3 for displaying
A screen display information storage unit that stores data of operation screens displayed via the CAM, for example, information of screen components such as operation switches, 5 is a screen display device such as a CRT installed on a monitoring operation panel, A touch panel 5a for operation is mounted on the screen. 6 is an operation permission switch provided on the monitor operation panel, 7 is a contact input processing unit for detecting whether or not the operation permission switch 6 is pressed,
Reference numeral 8 denotes a touch panel 5 which receives data from the display screen control unit 3, detects the contents of the display screen displayed on the CRT 5 screen and the position of the operation switch, and inputs an instruction by the operator.
an instruction input processing unit for detecting the operation content from the position a, and when the contact input processing unit 7 detects that the operation permission switch 6 is pressed, an operation instruction detected from the touch panel 5a is input to the process input / output processing unit. 2 is a processing unit that supplies the data to the processing unit 2. The instruction input processing unit 8 includes a contact input processing unit 7.
When the operation instruction is detected from the touch panel 5a when the operation permission switch 6 is not detected to be pressed, a message prompting the user to perform the operation again through the display screen control unit 3 is displayed on the CRT 5 through the display screen control unit 3. Display.

Next, the operation will be described. In the operating state of the plant 1, the process input / output processing unit 2 takes in the plant process amount from the plant 1 and supplies the data to the display screen control unit 3. In response to this, the display screen control unit 3 selects and reads out appropriate operation screen and screen display element information from the screen display information storage unit 4 based on the data, and reads the operation screen including the operation switches on the CRT.
5 is displayed. In other words, in this touch operation, basically, the operation switches on the surface of the monitor operation panel or the like are directly expressed on the screen of the CRT 5, and by operating the screen of the CRT 5 through the touch panel 5a, the hardware is operated. It has the same function as an operation panel composed of switches. The screen displayed on the CRT 5 can be freely changed via the touch panel 5a, and the operation instruction input area displayed on the screen at that time, that is, the display content and the position of the operation device are changed for each screen. Is different. Therefore, the display screen control unit 3 has information on which operation screen is currently displayed and on which position the operation switch is displayed, and the information is transmitted to the CRT 5. Is supplied to the instruction input processing unit 8 together with the display of the operation screen.

When the operator operates the operation switch displayed on the screen of the CRT 5 through the touch panel 5a in the same manner as the operation switch realized by hardware, the instruction input processing unit 8 sets the operation position. The position of the operation switch on the operation screen displayed from is detected, and its depression is detected. At this time, if the instruction input is input to an area different from the area intended by the operator due to the parallax on the screen, or if the instruction input is mistakenly input to a different operation device with some beat, An incorrect operation will result.

[0005] For this reason, when each of the operation switches on the operation screen displayed on the CRT 5 is instructed, the operator must simultaneously press the operation permission switch 6 provided as hardware on the panel to prevent erroneous operation. By
The instruction input processing unit 8 determines that the AND condition of the two instruction input signals from the touch panel 5a and the contact input processing unit 7 is the authorization of operation permission, and when there are both instruction input signals, the instruction from the operator is given. Treated as if there was input. The operation permission switch 6 is not pressed, and the touch panel 5
If only the operation a is detected, the instruction input processing unit 8 determines that the operation is erroneous, and prompts the CRT screen to input again through the display screen control unit 3.

As described above, the operation device in the conventional plant operation system has a multi-stage operation by adding a mechanical protection device for the operation permission switch 6 together with the touch operation of the CRT 5 so that the operator can make an erroneous operation. The operation was not performed. In addition, the number of operation switches or the operation range displayed on the screen of the CRT 5 is switched and limited by the display screen control unit 3 so as to reduce the ratio of erroneous operations, and to enable the operator to perform erroneous operations. Measures have been taken such as displaying on the screen an instruction to be input again from the instruction input processing unit 8 via the display screen control unit.

[0007]

Since the operating device in the conventional plant operation system is configured as described above, it is separately provided on the operating panel when a touch operation is performed on the CRT 5 through the touch panel 5a. It is necessary to press the operation permission switch 6 every time the operation is performed. As a result, there is a problem that the operation is multi-stage and the operation becomes complicated. At this time, the monitor of the screen of the CRT 5 and the button operation of the operation permission switch 6 on the panel are simultaneously requested, and the C which is being monitored for the button operation is requested.
The user must keep an eye on the screen of the RT5, and there is a problem that the operability and the reliability of the driving operation are lacking due to the necessity of integrating monitoring and operation while looking at the screen.

Further, in the conventional operating device, even if the operation permission switch 6 for preventing erroneous operation is provided, if the erroneous operation is performed after the operation permission switch 6 is pressed, the operation is protected. There was a problem that no measures were taken. In this case, since the selection of the necessary operating device is left to the operator, there is a high possibility that the operating device will be erroneously determined in an emergency, and there is no support for the operator's determination. Some further assistance was needed from the point of view.

The inventions of claims 1 to 4 have been made in order to solve the above-mentioned problems, and to prevent erroneous operations in a conventional touch operation and further improve operability and reliability. It is an object of the present invention to obtain an operating device in a plant operation system capable of performing the following.

[Embodiment 1] An embodiment of the present invention will be described below with reference to the drawings. FIG.
10 is a block diagram showing a system configuration of an operating device in a plant operation system according to an embodiment of the first aspect of the present invention. The corresponding parts in FIG. In this figure, reference numeral 9 denotes an operation determining unit that estimates an operating device to be operated based on the state of the plant 1 and determines whether the operation is being performed appropriately. In the operation determination unit 9, a plant state grasping processing unit 10 captures process data representing the state of the plant 1 from the plant input / output processing unit 2 and grasps the state of the plant 1. Based on model data and operation rules of the plant 1 stored in the storage unit 11 and the operation knowledge storage unit 12 in advance, a plant function group to be operated by performing an evaluation of an abnormal state of each plant function and narrowing down the abnormal state range is determined. It is a processing unit to determine. Reference numeral 13 denotes an operating device determining unit that determines an operating device to be operated by the operator from the plant function group determined by the plant state grasping processing unit 10, and is stored in advance in an operating device knowledge storage unit 14 described later. A processing unit that determines an operation device based on the operation device data. An erroneous operation determination process 15 compares the operating device determined by the operating device determining unit 13 with the operating device represented by the instruction input information from the instruction input processing unit 8 to determine whether the operation is appropriate. When the operation is appropriate, the operation execution permission instruction I is sent to the instruction input processing unit 8 to enable the operation.

FIG. 2 is a functional block diagram showing a more detailed configuration of each of the above units. In this figure, a plant state grasping processing unit 10 has a process amount input unit 10a, an operation target determination unit 10b, a hierarchical model reading unit 10c, an operation knowledge reading unit 10d, and a range of interest estimation unit 10e. ing. The process amount input unit 10a is a data input unit for inputting the process amount fetched from the plant 1 by the process input / output processing unit 2 at every predetermined diagnosis execution cycle. In particular, when an alarm is generated in the plant 1, a signal indicating the alarm is notified to the operation target determination unit 10 b, and a process amount characterizing the cause of the abnormality in the plant 1 is selected. This is supplied to the estimating unit 10e. The operation target determination unit 10b is a processing unit that determines an operation target in accordance with the operation target determination rule read via the operation knowledge reading unit 10d and supplies a read instruction to the hierarchical model read unit 10c. The operation target of the plant 1 is determined whenever the process amount and the alarm signal are received from 10a. The hierarchical model reading unit 10c is configured to select an operation target determining unit 10b from a plurality of plant function hierarchical models stored in the plant function hierarchical model storage unit 10.
Is a data reading unit that selects and reads out the plant function hierarchical model including the operation target determined in the above. The operation knowledge reading unit 10d is a data reading unit that appropriately reads out the driving target determination rule and the attention range estimation rule used for the respective processes by the driving target determination unit 10b and the attention range estimation unit 10e from the driving operation knowledge storage unit 11. is there. The attention range estimating unit 10e is configured to read the plant function hierarchical model read by the hierarchical model reading unit 10c, that is, the progress status of the abnormality progression of the hierarchical model including the operation target determined by the operation target determining unit 10b and the current status. The hierarchical level to which the abnormal event belongs in the model is estimated according to the process amount from the process amount input unit 10a and the attention range estimation rule read by the operation knowledge reading unit 10d, and the abnormal state range on the model is estimated. This is a processing unit for narrowing down.

The operating device determining unit 13 includes a target device extracting unit 13a, a device knowledge reading unit 13b, and an operating device estimating unit 13c. The attention device extracting unit 13a selects one of the attention range estimation regions of the hierarchical model narrowed down by the attention range estimation unit 10e of the plant state grasping processing unit 10 and supplies the selected region to the operation device estimation unit 13c. It is. For example, as shown in FIG. 3, the attention range of the operator is generally not single according to the state of the plant, so it is necessary to handle a plurality of attention ranges. For this reason, the priorities of the plurality of attention range estimation areas are determined using the attention range estimation rule described above. In FIG. 3, units B,
When C and E are abnormal, the units B and C have a hierarchical relationship, so that the unit C is included in the focal region of the unit B. Assuming that the priority of the unit B is higher than that of the unit E, the range of interest having the unit B at the top has a higher priority. As a result, the framework and the ranking of the region to which the operator should pay attention are determined, and the equipment of interest is selected according to the ranking. The device knowledge reading unit 13b is a data reading unit that reads operation device data from the operation device knowledge storage unit 14 and supplies the operation device data to the operation device estimation unit 13c. The operating device estimating unit 13c is a processing unit that estimates the device to be operated by the operator among the devices of interest from the device of interest extracting unit 13a based on the operating device data read via the device knowledge reading unit 13b.

The erroneous operation determination processing unit 15 of the present embodiment
Are the estimation device extraction unit 15a and the operation instruction reading unit 15b
And a determination unit 15c. Estimation device extraction unit 15
Reference numeral a denotes a processing unit for sequentially extracting the name data of the operating device determined by the operating device determining unit 13, and includes a buffer for storing the fetched device name data. The operation instruction reading unit 15b is a data input unit that reads the name data of the operating device based on the instruction input of the operator detected by the instruction input processing unit 8. The determination unit 15c includes an operation instruction reading unit 15b
Is compared with the device name of the estimated device extraction unit 15a to determine whether the operation is appropriate. If the operation is appropriate, an operation execution permission instruction I is sent to the instruction input processing unit 8. It is a processing unit.

Returning to FIG. 1, the plant function hierarchical model storage unit 11 uses the plant operation target to be achieved in the operation mode of the plant 1 as the top, and systematically functions to maintain this and the means for realizing it. And a first storage means for storing a hierarchically expressed plant function hierarchical model as a database. The plant function hierarchical model is embodied as a knowledge base with a functional image that the operator has for the plant 1. In other words, the plant function layered model is a plant operation target to be achieved by the operator in each operation mode of the plant,
For example, in a pressurized water reactor (PWR) operating plant, various operational functions for maintaining these functions are described below, with the maintenance of the output operation state, the maintenance of the hot shutdown state, and the maintenance of the cold shutdown state at the top. And their realization means are associated with driving operations, and are systematically and hierarchically developed according to their importance.

For example, FIG. 4 shows a pressurized water nuclear power plant (PW
R) In the case of a power plant, an example of a plant function hierarchical model in which the output operation state maintenance A1 is set to the target level A is shown. In the pressurized water nuclear (PWR) power plant, in order to maintain the power operation state A1, control of the core power, control of the core power distribution, control of the primary coolant holding amount, and control of the core heat removal function are performed. The essential functions include ensuring the soundness of the primary cooling system (not shown), heat sink control B1 and conversion B2 to electrical energy, and these are the next level of functional goals. Generally, these are critical availability functions (Cr
itical Availability Functions). Further, with regard to the heat sink control B1, the steam flow control B3 and the steam generator (SG) holding water maintenance B4 are support functions, and these two functions are the next-level function goals B together with the above functions. In addition, regarding the SG holding water maintenance B4, the main feedwater pump speed control C1, the SG water level control C2, and the like are positioned at the next control level C.
Hereinafter, in accordance with each function, detectors D1 to D3, a control system circuit D4, a valve D5, and a facility / equipment level D such as piping are sequentially developed.

In this model, a device fails and
If left unchecked, the effects will spread, and the higher-level functions will not be able to be maintained in order, eventually reaching the highest level and leading to a plant trip. In this sense, the plant function hierarchical model can be regarded as expressing the state of propagation of abnormalities. That is, in the figure, each function is related by a branch line, which indicates a transmission path of abnormality. Therefore,
If a higher-level function, for example, the SG water level control function C2 is infringed, it is expected that there is a cause candidate in the lower-level function group such as the SG water level detector D1 and the main feedwater flow control valve D5.

As described above, in the plant function hierarchical model according to the present embodiment, each functional target of the plant is expressed as a node (unit) of a hierarchical structure, and a branch connecting the units is a unit connected to the unit. It indicates that there is a functional dominance relationship between them. Therefore, the following points a, b, and c are considered in the relationship between the upper unit and the lower unit of the plant function hierarchical model. a. The upper unit indicates a target or a higher function to be achieved by the lower unit, and conversely, the lower unit indicates a support function or a lower function for achieving the upper unit. b. The upper unit has a higher abstraction and represents a higher concept including lower units, while the lower unit has a higher specificity and represents a lower concept that embodies the upper unit. c. Higher units represent deeper defenses in defense in depth, lower units represent shallower defenses. As described above, the data of the plant function hierarchical model in the present embodiment, especially under various plant conditions, takes into account the corresponding operations performed by the operator in the central control room, and It is configured using.

Returning again to FIG. 1, the driving operation knowledge storage unit 1
Reference numeral 2 denotes a second storage unit in which driving operation knowledge data in which operation rules formed based on the driving knowledge described in the driving manual and the empirical knowledge of the driving operation of the driver are stored. is there. In this embodiment, the operation target determination rule used in the operation target determination unit 10b of the plant state grasping processing unit 10 and the attention function estimation unit 10
An attention range estimation rule used in e is stored. The operation target decision rules are based on the process amount and plant 1
The operation mode to be maintained, for example, P
The WR operation plant is a rule that determines output operation, hot stop, cold stop, etc., and selects a plant function hierarchical model to be monitored for use in the following processing. For example, the following condition (if ) And the execution form. (Example) if SI signal: Generated then Plant function hierarchical model: Cold stop maintenance selection In this case, the cold stop maintenance operation target is set under the condition that an alarm signal called SI signal is generated from the plant 1. The plant function hierarchical model to be selected is executed.

The rule of interest estimation is that the plant 1
Is a rule for estimating which control function the operator should give priority to, based on the abnormal symptom information, for example, the threshold value calculation of the process amount, the alarm generated in the plant 1, and the diagnosis result from various diagnosis functions. That is, this is a rule for extracting a functional range (subset) on the plant function hierarchical model that is considered to be an area that the operator should pay attention to with the highest priority. (if) and execution (then) format. (Example) if unit "Pressure pressure control" and unit "Pressure water level control": Deterioration or radiation monitor: There is a symptom then unit "Pressure pressure control": High priority attention area. For the condition that the pressurizer pressure control unit and the pressurizer water level control unit need to monitor for signs of function deterioration or radiation in the process data, the priority area of attention is to select the function of pressurizer water level control. Execute

As described above, the operation knowledge database according to the present embodiment extracts the plant operation know-how and its behavior obtained from the operation experience of the operator by direct interview with the operator, and describes the operation manual. It summarizes the knowledge about the driving operation that is performed, and the condition (if)
And the above two rules configured by an execution form.

On the other hand, the operating device storage unit 14 stores a correspondence table describing the correspondence between the names of operating devices operated by the operator and each plant function which is an element of the plant function hierarchical model, based on the operating procedure. It is a third storage unit that stores an operation device database created in advance. An example of the operation device knowledge database according to the present embodiment is shown below as Table 1.

[0030]

[Table 1]

Next, the operation will be described. In the operating state of the plant 1, when the process input / output processing unit 2 receives process data representing the state of each unit of the plant 1 from each unit of the plant 1, the data is sent to the process amount input unit 10 a of the plant state grasping processing unit 10. Then, the data is sequentially taken in each diagnosis execution cycle and supplied to the operation target determination unit 10b and the attention range estimation unit 10e. The operation target determination unit 10b that has received the process data reads the operation target determination rules from the operation knowledge database via the operation knowledge reading unit 10d, and according to the rules, stores the plurality of operation target determination rules stored in the plant function hierarchical model storage unit 11. Decide which plant function layering model to use from among the plant function layering models. For example, in the case of a PWR operation plant, the process target input unit 1
When the SI signal generated in the plant 1 is received via Oa, the cold stop maintenance is determined as the operation target in accordance with the condition, and the resulting instruction signal is supplied to the hierarchical model reading unit 10c. Thereby, the plant hierarchical model reading unit 1
In step 0c, the plant function hierarchical model having the cold shutdown maintenance at the top is selected and read from the hierarchical model storage unit 11, and supplied to the attention range estimation unit 10e.

Next, the attention range estimating unit 10e, which has received the plant function hierarchical model having the operation target determined by the operation target determining unit 10b at the top, determines the abnormal state of each plant function which is an element of the model. The evaluation is performed using the characteristic model and the process amount that characterizes the cause of the abnormality from the process amount input unit 10a. In particular, in the case of a detector having multiplicity, the majority principle is used, and devices such as a controller and a filter are evaluated using a model comparison method. Next, the attention range estimating unit 10e compares the plant function hierarchical model with the result of evaluating the phenomenon actually occurring in the plant 1, and compares the progress of abnormalities and abnormalities on the plant functional hierarchical model. The degree of analysis is performed to detect which hierarchical level of the current abnormal event belongs to this model, and to narrow down the abnormal state range on this model. At this time, the attention range estimation unit 10e reads the attention range estimation rule of the driving operation knowledge database stored in the driving operation knowledge storage unit 12 via the operation knowledge reading unit 10d, and estimates the attention range according to the rule. I do.

For example, when an abnormality occurs in a plant,
First, the operator positions all the generated alarms (abnormalities) as targets to be monitored, and selects and determines information to be truly monitored from among them in consideration of the priority. The processing here realizes such a behavior pattern of the operator by the following procedure. First, among the units of the plant function hierarchical model, the activated unit, that is, the unit determined to have lost the function by the unit evaluation, is extracted as the operator's attention. Since the unit (activation unit) that has become abnormal due to equipment failure or accident is at least one of the units within the range to be monitored, the abnormal unit is taken as the top, as shown in FIG. Defines a divergent area (triangle) on the lower side. Then
Based on the structural characteristics of the plant function hierarchical model, the higher the model, the higher the importance is. Therefore, of the activated units, priority is given to monitoring the higher unit.

Therefore, the positional inclusion relation between the units is examined, and when the inclusion relation is established in the attention area estimation area, the attention area estimation area is determined from a more comprehensive viewpoint.
For example, in the case of a PWR power plant, if an alarm indicating “large pressurizer water level deviation” and an alarm indicating “low pressurizer water level” are issued in the plant 1, the operator sets “pressurizer water level low”. This is equivalent to shifting the range of interest to related information. In this case, as shown in FIG. 3, the attention range of the operator is generally not single according to the plant state, so that it is necessary to handle a plurality of attention ranges. For this reason, the priority order of the plurality of attention range estimation areas is determined by using the above attention range estimation rule. For example, in FIG. 3, when the units B, C, and E are abnormal, the units C are included in the focal area of the unit B because the units B and C have a hierarchical relationship. The unit B is the unit E
Assuming that the priority is higher, the attention range having the unit B at the top has a higher priority. In this way, the operator determines the framework and ranking of the areas to be noted. When the attention range of the hierarchical model is determined by the attention range estimation unit 10e as described above, these are sequentially extracted by the attention device extraction unit 13a of the operation device determination unit 13, and the operation device estimation unit 13c
Supplied to

Next, the operating device estimating unit 13c reads out the operating device database from the operating device storage unit 14 via the device knowledge reading unit 13b, and based on this database, the plant function The operation device corresponding to is determined. The names of the operating devices estimated by the operating device estimating unit 13c are sequentially extracted by the estimated device extracting unit 15a of the erroneous operation determination processing unit 15, and
It is stored in the buffer or the like. On the other hand, the display screen control unit 3 displays a predetermined operation screen on a CRT (screen display device) 5 based on the process data from the process input / output processing unit 2. The operator who sees the screen operates a desired operation device via the touch panel 5a based on the driving knowledge described in the driving manual and the empirical knowledge of the driving operation. The operation instruction is sent to the operation instruction reading unit 15 of the erroneous operation determination processing unit 15 via the instruction input processing unit 8.
b. Accordingly, the determination unit 15c compares the name of the operating device according to the operator's operation instruction supplied to the operation instruction reading unit 15b with the name of the estimated device extracted by the estimated device extracting unit 15a, and makes an erroneous operation determination. Do.

In this case, the determination unit 15c of the erroneous operation determination processing unit 15 supplies an operation execution permission command to the instruction input processing unit 8 when the operation devices match, and supplies an erroneous operation signal for the operation devices that do not match. . Therefore, when the instruction input processing unit 8 receives the operation execution permission instruction from the erroneous operation determination processing unit 15, that is, when the selected operation is appropriate, the operation instruction input via the touch panel 5a is validated, and The instruction is supplied to the process input / output processing unit 2 to execute the operation of the plant 1. On the other hand, when the operation is not appropriate, the operation instruction of the operator is invalidated, and the display screen control unit 3 causes the display screen control unit 3 to generate a screen or the like indicating that the erroneous operation has been performed and display it on the CRT 5. As a result, the operator confirms the erroneous operation and redoes the input instruction again. As a result, in the present apparatus, if an erroneous operation is performed, the operation is not executed, and the operation is executed only when the operation instruction of the operator is appropriate.

As described above, the operating device in the plant operating system of this embodiment stores the plant function hierarchical model, the operating knowledge, and the operating device knowledge in the respective storage units 11, 12, and 14 as databases. Prepared,
Based on these and the process data representing the state of the plant 1, the state of the plant 1 is grasped by the plant state grasping unit 10, the device to be operated is decided by the operating device decision unit 13, and the device and the touch panel 5 a are attached. The operation performed by the operator is compared with the device operated by the operator via the screen of the CRT 5 to determine whether the operation is appropriate and the plant 1 is operated. In this case, the operation is not executed, and only when the operation instruction of the operator is appropriate, the operation is executed, and the erroneous operation prevention process is effectively realized.

In this embodiment, the data such as the plant hierarchical model is described by taking the example of the pressurized water nuclear power plant. However, in the present invention, other reactor type nuclear power plants and plants other than the nuclear power plant are used. In this case, similarly to the above-described embodiment, a model relating to the plant function and knowledge regarding the operation know-how may be constructed as respective databases.

Further, in the above embodiment, for convenience of explanation, each processing unit of the plant state grasping processing unit 10, the operating device determining unit 13, and the erroneous operation determining processing unit 15, or the plant function hierarchical model storage unit 11, The case where the storage units such as the knowledge storage unit 12 and the operation device knowledge storage unit 14 are individually installed has been described. However, these units may be integrated in one piece of hardware such as a central processing unit and a storage device. Good.
