Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a man-machine system for plant monitoring and equipment operation management, and more particularly to a system for selecting and controlling an operation object and operation contents through an interactive screen.

[0002]

2. Description of the Related Art In recent years, an operation console for remotely operating a plant monitoring control device or the like on a screen of a workstation or the like has become widespread.

In this example, as described in Japanese Patent Application Laid-Open No. 5-108143, target devices and operation switches on a graphically displayed plant system diagram are selected by an input device such as a mouse or a touch panel. Some operate target devices. In addition, JP-A-5-32
As disclosed in Japanese Patent No. 4236, the relationship between the type of device and the command that can be (or cannot) be given to the type is stored in a database to prevent inappropriate operation display.

Further, in the display of the monitoring screen, as in Japanese Patent Laid-Open No. 4-253093, the plant status and the operation status are taken in and the priority order at that time is obtained.
Some screens present a user with a screen having a high priority from a large number of screens.

On the other hand, in the field of information processing systems such as document and figure creation or data processing, as an operation method for performing an important operation on the screen, confirmation is performed before executing an operation such as "erase". A general method is to display a dialog window for the user and let the user perform confirmation work.

[0006]

In the above-described prior art screen operation method, it is difficult to completely avoid erroneous operations and time consuming operations in the methods of the information processing field for important operations. On the other hand, in the method in the field of supervisory control, it is possible to avoid an erroneous operation or display regarding a preset prohibition condition. However, it is limited to the alternative execution / prohibition, and it is difficult to deal with the operation according to importance such as lightness, difficulty, or priority. In this case, the degree of importance changes depending not only on the type of operation content, but also on the combination of the operation target (equipment) and the operation content, the operating state of the plant, etc., and it is not possible to flexibly handle such cases, so the burden on the user remains Is large and the reliability is low.

An object of the present invention is to provide a man-machine system that reflects the importance of an operation on an operation screen and appropriately supports the user's operation.

An object of the present invention is to provide a supervisory control system in which erroneous operation is prevented and safety is enhanced by strictly controlling execution permission in accordance with the importance of the target device or the combination of the target device and the operation content. It is in.

[0009]

According to a method of controlling a man-machine device of the present invention, in a man-machine device which gives a user's instruction to execute a predetermined process, one or more man-machine devices are displayed on a screen of the man-machine device. When the processing target and the image element indicating one or more processing contents are selectably displayed, and when the arbitrary processing target and the arbitrary processing contents are selected and the predetermined processing is executed, the processing target or the processing contents When the selection signal indicating the selection is received, when the selection signal is continued until the determined selection time based on the combination selection time determined according to the processing target or the combination of the processing target and the processing content The selection process is enabled, and the selection process is disabled when it is not continued.

Alternatively, on the screen of the man-machine device, an image element to be processed which performs an analog operation and an image element showing the processing content giving a variable processing amount thereof are selectably displayed, and an arbitrary processing object and an arbitrary processing object are displayed. When a processing content is selected and the predetermined processing is executed, when a selection signal indicating selection of the processing content is received, a reaction speed set for the processing target or a combination of the processing target and the processing content According to the above, the processing amount is moved and displayed on the image element of the processing content.

The man-machine apparatus of the present invention displays an image element indicating one or more processing targets and one or more processing contents, and outputs a selection signal indicating the processing target and the processing contents selected on the screen. Screen display control means, an object management means for defining a predetermined parameter for each combination of the processing target or the processing target and the processing content, receiving a selection signal of the processing target or a selection signal of the processing content, From the object management means, the parameter value set for the processing target or the combination is searched, and it is determined whether the selection signal satisfies the parameter value. And a selection control means for invalidating the selection process when not doing so.

The monitoring control system for equipment according to the present invention displays an image element indicating the type of equipment to be operated and the type of command of the operation content on the driving device which operates the equipment via the interactive screen, Interactive screen display control means for outputting a selection signal indicating the operation target and the operation content selected on the screen, and object management means for defining a predetermined parameter for each of the operation target or the combination of the operation target and the operation content And a selection signal of the operation target or the operation content is received, the parameter value set for the operation target or the combination is retrieved from the object management means, and a predetermined conversion for the selection signal is performed based on the parameter value. And selection control means for performing or canceling the selection processing according to the converted signal.

[0013]

The first function of the present invention is to enable / disable the processing according to the selection time. That is, if the operation target is selected on the operation screen and the duration of the selection signal generated during the selection operation continues to satisfy the defined selection time, the subsequent selection is permitted and Display is made. If the selection operation ends before the selection time, the selection process becomes invalid.

Alternatively, if the operation content is selected subsequent to the operation target on the operation screen and the selection operation of the operation content satisfies the selection time set or determined according to the combination of the selection target and the selection content, The selection process is executed, a screen display to that effect is displayed, and a control signal is output.

The selection time becomes longer as the importance of the operation target or the combination of the operation target and the operation content increases.
The user can feel the importance of the selection operation when the selection operation is invalidated or the length of the selection operation time is short, so that the operation becomes careful and the user can easily cancel the operation when he / she notices an erroneous operation. Of course, it is possible to almost completely prevent important operations from being performed by mistaken touch. According to the present invention as described above, the reliability and usability of the man-machine method are improved.

The second function of the present invention is to suppress the changing speed of the manipulated variable of the input device by the reaction speed. That is, when the operation content is variably set as the operation amount, it is selected by a mouse or the like, and when the movement amount is displayed on the slider or the like, the reaction speed is set or determined according to the combination of the operation target and the operation content. , Change the normal reaction speed and display. This reaction speed becomes slower as the degree of importance of the combination of the operation target and the operation content becomes higher, so that it is suppressed even when the user tries to suddenly change the operation amount, and the risk of hunting of the device due to the sudden change can be avoided. Further, the user can feel the importance of the operation target from the speed of the moving display, so the operation becomes careful and the reliability of the device operation can be improved.

Since the above-mentioned importance can be dynamically changed according to the operating state of the equipment, the operation of the equipment monitoring control system can be optimized.

[0018]

Embodiments of the present invention will now be described in detail with reference to the drawings. The same elements are denoted by the same reference symbols throughout the drawings.

FIG. 1 shows a block diagram of a plant monitoring control system to which a man-machine control device according to an embodiment of the present invention is applied.

The man-machine control unit 101 is composed of a work station having a central processing unit (CPU) 102 and a main memory 106.
The display device 112, the input device of the keyboard 113 and the mouse 114, and the plant control IO port (PI / O) 115 that mediates the output of control signals and the input of process signals to the controller 116 are connected via 18. .

The CPU 102 realizes a selection signal control function 103, an importance setting function 104, and an input / output control function 105, which will be described later, together with a processing program and data stored in the main memory 106. In the main memory 106, an operation target management table 107, an operation content management table 108, an importance setting table 109, a selection time definition table 110, in addition to a processing program (not shown),
The reaction rate definition table 111 and the above-mentioned functions are stored.

2 shows the structure of the operation target management table, FIG. 3 shows the operation content management table, FIG. 4 shows the importance setting table, and FIG. 5 shows the selection time definition table.

In the operation target management table 107, for each operation target number (1 to N) indicating the ID of the plant device, the specific gravity (lightness) of the role of the device, the priority, the degree of difficulty required for the device operation, etc. , One of the importance information ranks (1 to L) of the equipment in the plant is set. The degree of importance may not be set depending on the operation target.

In the operation content management table 108, for each operation content number (1 to M) indicating an ID such as open (open) or close (close), start (on) or stop (off), start or end, etc. One of the importance information ranks (1 to L) is set in consideration of the influence of the operation on the plant, the risk, the priority, and the like.

In the importance setting table 109, predetermined parameter levels (1 to K), in this example, selection time parameters are set for each importance information rank (1 to L). In the selected time definition table 110, actual time data is set for each parameter level (1 to K). The selection time in the illustrated example is set to increase by 1 second for each level.

It should be noted that the operation target management table and the operation content management table may be combined into one, and the relationship between the tables does not necessarily have to be the hierarchical structure as described above. That is, when the correspondence relationship between the object (a graphic element that can be selected on the screen, the operation target or the operation content here) and the importance is fixed, the object number and the rank of the control parameter may be directly associated with each other. Furthermore, when there is one control parameter, for example, only the selection time, the object management table or the importance setting table 10
You may set the data of the selection time directly in 9.

Next, the operation of the man-machine device configured as described above will be described by taking plant control as an example.

FIG. 6 shows an example of the operation screen of the plant displayed on the display device 112 of the man-machine device 101. The display device 112 has a well-known macro command function and is configured interactively.
A predetermined selection signal corresponding to the image element selected by 04 is generated. The screen may be a touch operation type.

On the screen of the display device 112, OPEN button 601 and CLOSE button 60 displayed in windows are displayed.
2, operation content selection area 1121 such as the end button 603
And an operation target selection area 1122 such as a graphically displayed plant system diagram. In the plant system diagram of this example, a valve 604 for controlling the flow rate of the fluid X flowing from the tank 607 through the pipe, and a flow divider 60 for the fluid X.
8, valves 605 and 606 for further controlling the flow rate of the fluid X divided by the flow divider 608 are shown.

Here, to open the valve 604, the valve 604 on the screen is selected (clicked) with the mouse 114, and then the OPEN button 601 is selected. Further, in order to perform the operation of closing the valve 604, after selecting the valve 604 on the screen with the mouse 4, the CLOSE button 602 is selected. The valve 604 on the screen is, for example,
Displays blue when closed and yellow when open.

7 and 8 show a processing flow by the man-machine device 101, mainly by the selection signal control function 103, which will be described below by taking the opening operation of the valve 604 as an example.

When the operator clicks the valve 604 on the screen, the man-machine apparatus 101 receives a target selection signal including the ID of the valve 604 (s101). This selection signal is continuously generated while the click is continued on the screen. The operation target management table 107 is searched using the ID of the valve 604 included in the target selection signal as a key (s102). Since the table 107 is hierarchically structured, the lower layer importance setting table 109 and the lower layer selection time definition table 110 are sequentially searched to acquire the selection time t1 defined in the valve 604.

Next, it is determined whether or not the selected time has been acquired (s103). If the selection time is not set for the valve 604 (no importance rank is set), the process proceeds to step s106. On the other hand, if the selection time is set in the valve 604, the continuation of the target selection signal is monitored (s10).
4). When the continuation of the target signal has reached the selection time t1 or has ended midway, it is determined whether or not it has continued until the selection time t (s105). At this time, the selection time t1
The transition of the duration of the target selection signal may be displayed as a percentage.

If the target selection signal ends before the selection time t1, the process proceeds to step s108, and the selection process of the operation target is canceled (the above percentage display is also erased).
After that, the process is ended (END) or the process returns to s101 to wait for the next target selection signal.

On the other hand, when the target selection signal continues until the selection time t1, the operation target selection completion signal is output (s10).
6), the operation target selection completion identification display is performed (s107), and the process A of FIG. 8 is activated. As the identification display, for example, the image of the valve 604 is displayed by flash. In addition, s
Steps 106 and s107 are processing for notifying the user that the next operation content can be selected (selection permission). Therefore, if the percentage display or the like is performed in s104, the process may be omitted and the process A may be immediately performed.

Process A starts, and the user performs OPE on the screen.
When the N button 601 is clicked, the man-machine device 10
1 receives an operation selection signal including the ID of the button 601 (s201). Then, the OP included in the operation selection signal
The operation content management table 108 is searched using the ID of the EN button 601 as a key (s202). Below, s1 described above
Similar to 03 to s105, the processing of s203 to s205 is performed. In addition, when No in step s103 and No in subsequent step s203, since the selection time is not set, selection is completed at the same time as clicking as in the conventional case.

When the operation selection signal ends before reaching the selection time t2, the process proceeds to step s209, the operation content selection process is canceled, and the process ends. On the other hand, when the target selection signal continues until the selection time t2, the operation content selection completion signal is output (s206), the operation selection completion identification display is performed (s207), and the plant control signal (open command of the valve 604) is issued. It is output to the controller 116 (s208). The operation completion identification display is displayed on the valve 604.
Is changed from blue (closed) to yellow (open).

According to this embodiment, a selection time for completing the selection process is defined for each operation target and each operation content, and if the click is continuously performed for more than the selection time, The selection process is disabled. The defined selection time is set to be longer as the importance of the operation target or the operation content is higher, so that an instant touch mistake can be avoided without any problem. Furthermore, since the selection on the screen is continued for the selection time of the operation target and then the selection time of the operation content, the user can perceptually recognize the importance of the operation target, the operation becomes careful, or the operation error occurs. Remarkably improve operation reliability and safety, such as notice and interrupt.

In the processing flow of FIGS. 7 to 8, s20
The processes of 2 to s206 can be omitted entirely.
That is, according to the defined selection time, the selection signal control that completes the selection after that is applied only to the selection process of the operation target, and after the selection of the operation content is permitted, the operation is immediately performed by clicking the operation button. . This also allows the user to recognize the importance of the operation target and improve the reliability and safety of the operation.

Next, a second embodiment of the present invention will be described.
In this embodiment, depending on the combination of the operation target and the operation content,
The feature is that the selection time is determined.

FIG. 9 shows a processing flow of the man-machine device according to this embodiment. The configurations of the man-machine device 101 and the tables 107 to 110 are the same as those of the first embodiment described above. Hereinafter, the operation of opening the valve 604 will be described as an example.

When the user clicks the valve 604 on the screen and then clicks the OPEN button 601, the man-machine apparatus 101 causes the man-machine device 101 to select the target selection signal including the ID of the valve 604 and the operation selection signal including the ID of the OPEN button 601. Is received (s301, s302). Valve 60
Operation ID management table 107, OPE
Operation content management table 1 using the ID of the N button 601 as a key
08 are retrieved, and the selected times t1 and t2 set for each are acquired (s303).

Next, it is determined whether or not the selected time has been acquired (s304). Valve 604 and OPEN button 601
If the selection time has not been set for both of the items (if there is no importance rank setting), the process proceeds to step s309, and the operation selection is immediately completed. If the selection time is set for one or both, the combination selection time is determined (s30
5). Then, the selected valve 604 is identified (for example, flashed) (s306), and the continuation of the operation selection signal is monitored (s307).

Here, the combination selection time t is the selection time t
It is determined according to a predetermined relationship such as the sum or product of 1 and t2. Alternatively, the combination time is determined from the relationship of the combination of the operation target and the operation content. In the latter case, the combination selection time t can be obtained directly from step s303, so
Step s305 is omitted.

FIG. 10 shows an object management table in the latter case. As shown in the figure, the importance degree information rank is set at a required position in the matrix of the operation target number and the operation content number. For example, valve 604
And the OPEN button 601 combination is importance 3, valve 6
The combination of 04 and the CLOSE button 602 is set to the importance level 1 or the like. In this object management table,
Similar to the first embodiment, the importance setting table 109 and the selection time definition table 110 are hierarchically structured, and the combination selection time can be determined from this. Of course, the selection time may be defined directly in the object management table.

Next, it is determined whether or not the operation selection signal has continued until the combination selection time t (s308), and if it has not continued, the process proceeds to step s312 to cancel the selection process (the identification display of the operation target is also erased. And return to the display before selection). On the other hand, when the combination selection time t is reached, the operation content selection completion signal is output (s309), and the operation selection completion identification display (the valve 604 image is changed from blue to yellow) (s3).
10), and outputs a plant control signal (s311).

In the plant, for example, even with the same valve, the degree of importance may differ by orders of magnitude between the opening operation and the closing operation. According to the present embodiment, it is possible to determine the selection time based on the detailed evaluation of the importance of the operation of the plant according to the combination of the operation target and the operation content, and further improve the reliability and safety of the operation. can do. Further, the user's selection operation is convenient because the operation content can be selected subsequently to the operation target.

In the first and second embodiments described above,
The importance or the selection time is fixedly set in advance. However, the importance or the selection time can be dynamically changed according to predetermined conditions.

FIG. 11 shows a driver ID table for managing the selection time correction coefficient for each driver ID, and FIG. 13 shows a selection time correction processing flow. The importance setting function 104 of the man-machine device 101 takes in the driver ID input from the keyboard 5 when starting the device (s401), searches the driver ID table, and acquires the correction coefficient thereof. The correction coefficient is set to 1 for a skilled person and set to a numerical value that becomes larger as an unskilled person (s402). Next, the set time of the table is updated with the correction value obtained by multiplying the time set in the selected time definition table 110 by the acquired correction coefficient (s4).
03).

FIG. 12 shows plant abnormality information (for example,
FIG. 14 shows an abnormality information table for setting the correction importance degree of the related equipment for each water level upper limit ON signal / lower limit ON signal of the tank S607, and FIG. 14 shows the importance degree correction processing flow.
The importance setting function 104 of the man-machine device 101 uses the PI
When an abnormal signal is received from the plant via the I / O 115 and the input / output control function 105 (s501), the abnormal signal table is searched to obtain the correction importance assigned to the related operation target ID (s502). Then, the importance of the corresponding operation target in the operation management table 107 is updated with the acquired correction importance. For example, when the water level upper limit ON signal of the tank 607 is received, the importance rank of the valve 604 is set to 0 and the setting of the selection time is canceled. by this,
The valve 604 can be opened immediately and the tank 6
07 overflow can be prevented. On the other hand, when the water level lower limit ON signal of the tank 607 is received, the importance rank of the valve 604 is significantly increased, making the opening operation virtually impossible. It should be noted that such correction importance is preferably determined from the above-mentioned object management table.

According to this, since the selection time or the importance can be dynamically changed, the control of the operation selection signal can be optimized according to the operating condition of the operator's carrier or plant.

Next, a third embodiment of the present invention will be described.
The present embodiment is characterized by the operation content such that the plant control signal is not turned on / off but is output as a continuous amount.

FIG. 15 shows a plant system diagram to which the present embodiment is applied and an operation screen composed of operation operation selection figures. Valves 1504, 15 of this plant system
Reference numeral 06 and the like are flow rate adjusting valves for continuously changing and controlling the opening degree. On the other hand, in the operation content selection area, the slider 1
The graphic elements of 501 and end button 1502 are shown.
To increase or decrease the opening degree of the valve 1504 on this operation screen, select the valve 1504 with the mouse and then move the slider 150
With the knob 1503 of No. 1 selected, move it in the opening or closing direction.

Now, from tank S1507 to facility C150
When the fluid X is being supplied to 9 at a certain constant flow rate, if the flow rate is changed to another constant flow rate, the opening degree of the valve 1504 is adjusted, and then the opening degree of the valve 1506 is adjusted. However, the valve 1505 is an open / close valve and is opened. In this case, in the comparison of the opening operation of the valve 1504 and the valve 1506, it is necessary to carefully operate the latter opening so as to settle stably with respect to the required flow rate, and the operation is highly important. In this embodiment, by defining the reaction speed of the operation with respect to the importance, the movement display of the valve 1504 is performed at the normal speed, and the movement display of the valve 1506 is performed at the speed of 1/3 of the normal speed. There is.

16 and 17, the importance setting table 10 is shown.
9 and the reaction rate definition table 111 are shown. The former defines a reaction rate level d for each importance rank (1 to H), and the latter defines a reaction rate coefficient for each reaction rate level (1 to G). This reaction speed coefficient is 1/2 in inverse proportion to the reaction speed level, where the reaction speed (movement display speed) of the knob 1503 on the normal screen with respect to the movement of the mouse is 1.
1/3 ,. ． ． Is set so that the reaction speed decreases.

FIG. 18 shows a processing flow of the man-machine device according to this embodiment. The configuration of the man-machine device 101 is similar to that of the first embodiment described above. Hereinafter, the operation of opening the valve 1506 will be described as an example.

When the user clicks the valve 1506 on the screen and then clicks the slider knob 1503, the man-machine apparatus 101 causes the man-machine apparatus 101 to select the target selection signal including the ID of the valve 1506 and the operation selection signal including the ID of the slider 1501. Is received (s401, s402). The object management table (FIG. 10) is searched by using the ID of the valve 1506 and the ID of the slider 1501 as keys, and the set reaction speed is acquired (s403).

Next, it is determined whether or not the selected time has been acquired (s404). When the reaction speed is acquired, it is passed to the display control function 105 ′. The display control function 105 'is
As part of the input / output control function 105, the normal reaction speed is changed to the received reaction speed (coefficient) (s405), and the slider knob 1503 is moved and displayed (s406). When the input / output control function 105 receives this knob position, the controller 1 sends a control signal requesting an opening corresponding to the knob position.
It outputs to 16 (s407). On the other hand, if the reaction speed is not acquired, the process proceeds to step s406, and knob 1
503 It is moved and displayed at a normal reaction speed.

According to this, the higher the importance of the operation target or the combination of the operation target and the operation content is, the slower the reaction speed is, so that the actual operation is not performed even if the user randomly moves the mouse. It is done carefully. Further, the importance of the operation is sensuously recognized by the user from the reaction speed of the display, and the careful operation is prompted. As a result, the reliability and safety of the operation can be improved without imposing a burden on the user.

Although the man-machine device and the control method thereof according to the present invention have been described with reference to the embodiments applied to the plant monitoring system, the present invention is not limited to this. For example, a building management system that manages many devices such as lighting, air conditioning, locking, disaster prevention, or a traffic control system that has traffic signals, input / output prohibition gates, etc.
Power system control systems with transformers, circuit breakers, etc.
It can be applied to equipment control systems in various fields and contribute to the reliability and safety of its operation.

[0061]

According to the man-machine system of the present invention, the reaction (completion time or reaction speed) to the operation on the operation screen is changed according to the importance of the operation target or the combination of the operation target and the operation content. Since it is displayed in such a manner, it is possible to assist the user to perform a more careful operation for an important operation, improve the reliability and safety of the operation, and have the effect of facilitating the operation.
