PURPOSE:To prevent misoperation, to perform operation output corresponding to a plant state and to lighten the burden on an operator by providing a priority index setting means which changes a setting from the presence of an operation signal in a priority processing to the absence of the operation signal. CONSTITUTION:This device has a precedent priority input decision means 8 which decides whether or not there is the operation signal in the priority processing by referring to indexes stored in a priority presence/absence storage means 7 and makes the inputted operation signal invalid when deciding that there is already an operation signal in the priority process. When it is decided that there is not the operation signal in the priority process, on the other hand, an operation output request is sent to an operation output means 3 and when a corresponding index in a priority index information storage means 9 wherein indexes showing whether or not inputted operation signals are preferentially processed are set and stored by the operation signals indicates the priority processing, the corresponding index in the priority presence/absence storage means 7 is set to the presence of the operation signal in the priority processing. Then the device is equipped with a priority index setting means 10 which changes the setting from the presence of the operation signal in the priority processing to the absence of the operation signal of the priority processing when an operation completion report is inputted from the operation output means 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operating device for operating a plant by operating information operated from an input device based on plant information displayed on a display device.

[0002]

2. Description of the Related Art Conventionally, in a power plant, an operation panel having an operation switch is provided for each device,
This was used to give operating instructions for various devices and control devices. However, recently, for the purpose of downsizing the operation room and reducing the hardware cost of the operation switches, there has been an operation device which operates by a display device such as a CRT and an input device for inputting a position touched on the display device. It is becoming mainstream.

FIG. 29 shows a conventional example of this type of operating device.

This operating device includes a computer 4 having a reception range information storage means 1 for storing the presence / absence of an operation output corresponding to the input operation information, an operation input means 2 and an operation output means 3, and a display device 5A. The display device 5A includes an input device 5 including a touch operation device 5B for touch input and an output device 6 for outputting an operation output corresponding to information operated by an operator to a plant.

With this configuration, when the operator operates and inputs from the touch operation device 5B of the input device 5, information is input to the operation input means 2 of the computer 4 as coordinate data of the touch area. The operation input means 2 first inputs the coordinate data of the touch area by the processing procedure shown in FIG. 30 (101). Next, the coordinate data of the touch area is shown in FIG.
It is sequentially searched from index = 0 whether or not it is stored in advance in the reception range information storage means 1 having the configuration (102,
103, 104).

The acceptance range information storage means 1 stores the coordinates corresponding to the acceptance range index = 0 to index = n for each screen. Here, if there is coordinates of the touch area in the reception range information storage means 1, the operation output means 3 receives i.
The operation signal corresponding to the index is notified (105). These processes are repeated up to the reception range number (106).

The operation output means 3 outputs a corresponding operation signal to the output device 6 in response to a request from the operation input means 2. The output device 6 outputs an operation command to the operation device based on the operation signal. As a result, the operator operates the input device 5
The operation content input from is output to the output device 6 by the processing of the computer 4.

For example, it is assumed that the operator selects an operation screen on the display device 5A as shown in FIG.
In this operation screen, the system is displayed as "A system", "B system", the valve types are "X valve", "Y valve", "Z valve", and the commands are "open" and "closed". , Y coordinate data and the definition contents of the acceptance range information storage means 1 shown in FIG. 31 are matched in advance for each operation screen. Therefore, when the system A is touched on the operation screen, the operation input unit 2 determines whether the input x, y coordinate data is in the acceptance range information storage unit 1,
For example, "1" is set to the bitmap output signal shown in FIG. 33 and the operation signal shown in FIG. 34 is output to the operation output means 3.

Next, when "X valve" is selected, a bit map output signal as shown in FIG. 35 is output to the output device 6,
When "Open" is selected, the bitmap output signal shown in FIG. 36 is output. Data for interpreting a bitmap output signal is stored in advance in the output device 6 for each operation screen. For example, the sequence circuit operates so as to specify the A system by the bitmap output signal shown in FIG. The X valve is specified by the bit map output signal shown, and an opening command is output to the X valve by the bit map output signal in FIG. As a result, the X valve is opened and the result is displayed on the display device 5A.

[0010]

However, in the operation device described above, if the same operation signal as the operation signal input by operation is present in the acceptance range information storage means 1 defining the acceptance range, the operation output means 3 is unconditionally operated. Since it is output to the output device 6 via the, there is a possibility that an erroneous operation or the like will be performed as follows, and an operator's burden is heavy because an operation depending on the operator's judgment is required.

First, when a touch operation is performed on the display device 5A, it may be necessary to operate in accordance with a predetermined operation sequence. However, the operation device shown in FIG. 29 has no interlock means. Even if an unnecessary operation or an erroneous operation is performed by ignoring this, there is a risk that the output device 6 may directly output the data.

For example, in the operation screen shown in FIG. 32, "X system" is selected without selecting "A system" or "B system" by the touch operation device 5B.
If "valve" is selected and then "open" is selected, there is a possibility that the operation output will be output from the output device 6 as it is.

Further, in the operating device shown in FIG. 29, only a uniform operation is desired, and as a result of requiring the operator to perform an operation according to the state of the plant, the burden on the operator is large and the operation according to the state of the plant is required. There is a problem that it is difficult to perform the optimum operation.

Therefore, an object of the present invention is to provide an operating device capable of preventing an erroneous operation and outputting an operation according to a plant state to reduce the burden on an operator.

[0020]

According to the first aspect of the invention, when the operation signal corresponds to the priority processing, the corresponding index of the priority presence / absence storage means is set to the index of the operation signal having the priority processing, and the priority is given to the operation output means. When the operation completion notice is input, the setting of the operation signal with priority processing is changed to no operation signal with priority processing. As a result, the operation signal to be preferentially processed is input and the other operation signals can be invalidated during the preferential processing.

According to the invention of claim 5, when a certain operation procedure is selected, the selection operation of the next operation step becomes effective, and when that operation is selected, the selection operation of the next operation step becomes effective. Therefore, the operation content becomes the same as when the operator operates the operation switch of the conventional operation panel, and when one operation is performed, the operation of the next step becomes effective, so that the operator's erroneous operation is prevented and the operator's operation is prevented.

[0025]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an operating device showing a first embodiment of the present invention. 29. FIG. 1 shows a conventional example. The same reference numerals as those in FIG. 29 indicate the same parts or corresponding parts, and the difference between them is that the computer 4 of FIG. That is, the storage means 9 and the priority index setting means 10 are additionally provided.

Here, the priority presence / absence storage means 7 stores whether or not the operation signal to be preferentially processed is currently being processed by an index.

When the operation signal is input, the first-priority input determination means 8 refers to the index stored in the priority presence / absence storage means 7 to determine the presence / absence of the operation signal being subjected to the priority processing. When there is an operation signal being processed, the input operation signal is invalidated.

The priority index information storage means 9 presets and stores, for each operation signal, whether or not to preferentially process the input operation signal, for each operation signal.

The priority index setting means 10 invalidates the input operation signal when the priority priority input determination means 8 judges that there is an operation signal under priority processing, and judges that there is no operation signal under priority processing. At this time, while making an operation output request to the operation output means, when the corresponding index of the priority index information storage means 9 is the priority processing, the corresponding index of the priority presence / absence storage means is set to the index having the operation signal during the priority processing, When an operation completion notification is input from the operation output means, the setting of the operation signal being in the priority processing is changed to the operation signal not being in the priority processing.

First, when the operator inputs an operation from the touch operation device 5B based on the display on the display device 5A, x,
An input signal as y-coordinate data is input to the operation input means 2. The operation input means 2 compares the operation input with the operation input stored in the operation input reception range information storage means 1 shown in FIG. 31, and determines whether or not the operation input is valid. When it is validated by this judgment, the operation input means 2 notifies the first priority input judgment means 8 of the operation signal as a corresponding bitmap output signal.

When the input operation signal is notified to the first prioritized input judging means 8, the first prioritized input judging means 8 will be used.
Processing is performed as shown in.

First, the prioritized input determination means 8 determines from the index of the priority presence / absence storage means 7 whether the operation signal to be preferentially processed is currently input and is being processed. For example, the priority presence / absence storage unit 7 is set to 0 corresponding to the operation signals 0 to n as shown in FIG.
Alternatively, if all the operation signals are stored as 0, it is indicated that there is no operation signal being prioritized in the operation signals input before this time, and at least one operation signal is stored. When 1 is stored for the operation signal, it indicates that the operation signal input prior to this time includes an operation signal for which priority processing is being performed.

In this case, if there is at least one index of 1 in the priority presence / absence storage means 7, the priority input determination means 8 inputs that the operation signal for priority processing has already been input and is currently being processed. Invalidate the operation signal that has been set (20
1). As a result, the operation signal currently being processed is preferentially processed.

On the other hand, if all the indexes in the priority presence / absence storage means 7 are 0, the operation signal is notified to the priority index setting means 10 on the assumption that the operation signal for the priority processing has not been input yet (202).

In the priority index setting means 10, the processing is performed as shown in FIG. 4. First, when the operation signal is notified from the first priority input determination means 8, it is stored for each operation signal whether or not the operation signal has priority. By referring to the priority index information storage means 9 described above, it is determined whether or not the operation signal notified is a priority operation signal (302).

For example, the priority index information storage means 9 is shown in FIG.
As shown in (1), 1 is stored in advance when the priority processing is performed in correspondence with the operation signals 0 to n, and 0 is stored as the index when the priority processing is not performed.

In the priority index setting means 10, when the notified operation signal is stored in the priority index information storage means 9 with an index of 1, priority is given to the corresponding operation signal in the priority presence / absence storage means 7 as shown in FIG. Set status 1 to indicate that processing is in progress (3
03). Then, the priority index setting means 10 makes a request for operation output to the operation output means 3 (304).

When the operation output means 3 receives the operation output request, it outputs to the output device 6. When the operation output is completed, the priority index setting means 10 is notified of the completion of the operation output. When the priority output setting unit 10 is notified by the operation output unit 3 that the operation output is completed, the operation output of the operation signal in the priority process is completed. The current 1 index of the corresponding operation signal is changed to 0 to indicate that there is no (305).

As a result, the operation signal input next becomes valid.

For example, assuming that there are operation signals A, B, C, D, E, and F, and C is set as an operation signal for preferential processing, first, the operation signals of A and B are sequentially input to the operation input means 2.
Is input to the output device 6 from the operation output means 3.

Next, assuming that the operation signal of C is input, the index 1 is stored in the priority presence / absence storage means 7 for processing, and the operation output means 3 waits for the notification of the completion of the operation output.
In the meantime, even if the B and E operation signals are sequentially input to the operation input means 2, the operation signal of C is prioritized and the processing of invalidating the B and E operation signals is not performed, and the operation output means 3 is operated. No output request is made.

For example, if the operation signal of F is input after the operation output means 3 notifies the operation signal of C that the operation output is completed, normal processing is performed. Thus, for example, when the processing of the operation signal of D is completed before the processing of the operation signal of C is completed, it affects the state after the processing of the operation signal of C and causes C in advance when it causes a malfunction. A malfunction can be prevented by giving priority processing.

Explaining in a concrete example, there is a triple water supply system consisting of an A pump, a B pump and a C pump, and when only one pump is started, the A pump,
If priority processing is set for the index of the priority index information storage means 9 corresponding to the operation signals of the B pump and the C pump, first,
Even if the A pump is operated and then the B pump and the C pump are operated, the operation of the B pump and the C pump can be invalidated. Therefore, it is possible to prevent the A pump, the B pump, and the C pump from being operated at the same time.

As described above, after the operation signal for priority processing is input, the operation signal for priority processing is output to the output device 6 for completion, or until the operation signal for canceling priority, which will be described later, is input, the next operation signal is input. Can be disabled. Therefore, the prioritized processing similar to the operation switch of each operation panel of the conventional operation device can be individually set, and an erroneous operation can be prevented, and an operator's burden can be reduced.

Next, a second embodiment of the present invention will be described with reference to FIG.

The same reference numerals as those in FIG. 29 showing the conventional example in FIG.
The same part or the corresponding part is shown, and the difference between them is that the priority index information storage means 9, the rear priority input determination means 11, the selected index storage means 12, and the selected index setting means 13 are additionally provided. If it is carried out integrally with the first embodiment, the post-priority processing according to the second embodiment can precede the processing even during the first-priority processing.

The priority index information storage means 9 presets whether or not to perform the post-priority processing for each operation signal by using an index.

The rear-priority input determination means 11 determines whether or not the operation signal is to be subjected to the rear-priority processing based on the input operation signal and the corresponding index stored in the priority presence / absence storage means 7. When the operation signal is to be processed, other operation signals being processed are invalidated, while the operation signal to be processed after the priority determination in the above determination is not applicable and the selected index storage means 1
When there is an operation signal in the process of being selected from the indices of 2, the input operation signal is determined to be the presence or absence.

The selected index storage means 12 stores, by an index, whether the operation signal has already been input before the input operation signal and is being selected or not selected.

The selected index setting means 13 makes an output request to the operation output means 3 when the rear priority input determination means determines that it is not selected, and the rear priority input determination means 11 determines that the operation signal is to be subjected to the rear priority processing. During processing, after the operation signal of the priority processing is output from the output device, the corresponding index of the selected index storage means 12 is set to the unselected index.

First, when an operation is input from the input device 5,
The operation information is input to the operation input unit 2, and it is determined whether or not the input operation information is valid by referring to the acceptance range information storage unit 1, and the valid selected operation signal is sent to the rear priority input determination unit 11. Be notified.

When the operation signal is notified, the rear priority input determination means 11 determines from the index of the priority index information storage means 9 whether or not the operation signal is to be subjected to the rear priority processing based on the processing shown in FIG. In the priority index information storage means 9, the index 1 or 0 is indicated corresponding to each operation signal, and the index 1 is stored as the post-priority process.

When the rearward priority input determining means 11 determines that the notified operation signal is the operation signal to be subjected to the rearward priority processing from the index of the priority index information storage means 9, it notifies the selected index setting means 13 of the operation signal. (402).

Further, when it is determined that the notified operation signal does not correspond to the operation signal to be subjected to the post-priority processing from the index of the priority index information storage means 9, it is determined whether the operation signal input before this time is being processed. It is determined whether or not the selection process is currently being performed from the index of the selected index storage means 12 that stores this (4
03).

For example, the selected index storage means 12 is shown in FIG.
As shown in, the index of 0 or 1 is stored. When 0 is stored, it indicates that there is no operation signal currently being selected, and when 1 is stored, the current selection process is performed. Indicates that there is an operation signal inside.

In this case, the rear priority input determination means 11 is
The selected index storage means 12 is referred to, and if even one of the stored indexes is 1, it is determined that there is a selected operation signal, and the operation signal input this time does not correspond to the post-priority processing. If it is a signal, the operation signal input this time is invalidated. Further, the rear priority input determination means 11 refers to the selected index storage means 12, and if the stored index is 0, determines that there is no operation signal being selected and sets the operation signal to the selected index. Notify the means 13.

The selected index setting means 13 performs the processing as shown in FIG. 9, and when the rear priority input determination means 11 notifies the operation signal of the rear priority processing, the selected index storage means 1
1 is stored to indicate in 2 that the selection process is being performed (501) (502). Then, the selected index setting means 1
3 requests operation output to the operation output means 3 (50
3).

Upon receiving the operation output request, the operation output means 3 outputs an operation to the output device 6. When the operation output is completed, the selected index setting means 13 is notified of the completion of the operation output. The selected index setting means 13 is the operation output means 3
When the completion of the operation output is notified from, the operation output processing of the operation signal being selected is completed, so 0 is stored in the selected index storage means 12 to indicate that there is no operation signal being selected, and The operation signal input to is validated (504).

For example, in an operating device capable of processing only one of the A and B operation signals, if the B operation signal is set to be given the second priority, B is input after A and A is input. B is preferentially processed even during selection processing.
This is effective when the state of the processing result of B is influenced by the processing result of A and causes a malfunction.

When the post-priority process is added to the first embodiment, the first-priority process is set for the A pump, the B pump, and the C pump, and the operation signal of the A pump is input to the first-priority process. As a result, if the operation signal is input as a post-priority processing for canceling even during processing, the operation signal of the A pump can be canceled. In this case, the B pump or the C pump can be newly selected.

According to the second embodiment, if there is an operation signal that is already selected, the next operation signal can be invalidated until the operation output of that operation signal is completed. Further, even if there is an operation signal that is already selected, it is possible to receive a specific operation signal in the post-priority process and perform an operation output. Therefore, the rear priority can be individually set and the rear priority processing can be performed similarly to the operation switch of the conventional operation panel, so that the operator's erroneous operation can be prevented and the burden on the operator can be reduced.

Next, a third embodiment of the present invention will be described with reference to FIG.

29. FIG. 10 shows a conventional example. The same reference numerals as those in FIG. 29 indicate the same or corresponding portions. The difference between the two is that the computer 4 has the operation condition information storage means 14, the condition state storage means 15, and the operation condition determination means. In the third embodiment, the device is selected by additionally providing the means 16, the condition state control regulation information storage means 17, and the condition state control means 18, for example, turning on / off the touch operation device 5B as an operation command. Even when the device is operated by pressing it on, it can be operated like a conventional switch panel.

Here, the operating condition information storage means 14 sets the operating condition in advance for each operation signal using an index. The condition state control regulation information storage means 17 is set with information in advance in order to create a condition state for the operation signal ON or OFF for each operation signal. The condition state storage means 15 stores the processing result of the operation condition determination means 16 as a condition state as an index.

The condition state control means 18 is a condition that becomes an operation condition corresponding to the operation signal input this time from the setting information of the condition state control regulation information storage means 17, the state of the operation signal and the condition state of the condition state storage means 15. The state is obtained and stored in the condition state storage means 15.

The operating condition judging means 16 judges whether or not a predetermined condition is met from the operating condition of the operating condition information storage means 14 and the condition state of the condition state storage means 15, and when they match, the operation output means 3 The operation output request is made to.

First, the operation screen is displayed on the display device 5A, the operator selects the equipment by the acceptance range information storage means 1 in the first and second embodiments, and outputs the bit map output signal. I shall.
Next, the operator turns on / off the touch operation device 5B to input an operation command.

Specifically, the processing of the condition state control means 18 will be described with reference to FIG. 11. First, the touch operation device 5 will be described.
When the state of the operation signal having the information that the state where the B is pressed is turned on and the state where the B is released is turned off is notified, the condition state control means 18 causes the condition state control means 18 to store the condition state stored in the condition state storage means 15. And the information of the operation signal notified from the conditional state control regulation information storage means 17.

Here, the condition state control regulation information storage means 1
In FIG. 7, 0 or 1 is preset in the positions of bit 0, bit 1, and bit 2 for each operation signal as shown in FIG. 12, and the condition state storage means 15 is operated as shown in FIG. A 0 or 1 condition state is stored for each signal.

For example, when the operation signal ON is input from the operation input means 2, the processing as shown in FIG. 14 is performed (6
01, 602).

First, as shown in FIG. 14, when the operation signal is on, bit 0 of the condition state control regulation information storage means 17,
1 and 2 are 0, 0 and 1, and the condition state of the condition state storage means 15 is 0. Under this condition, the condition state control means 18 reads the information (0) of bit 0 of the condition state control regulation information storage means 17, and the 1 signal via the NOT 18a and the operation signal on from the operation input means 2 are input to the AND 18b. And outputs a signal of 1, while the condition state storage means 15
The condition state (0) and the operation signal ON are input to the AND 18c, and the signal [1] is AND1 via the NOT 18d.
Output to 8e.

In AND18e, 1 from AND18b
Input 1 from NOT 18d and output 1 to OR 18f. On the other hand, in AND18h, the output of 0 of AND18c and the bit (0) of the condition state control regulation information storage means 17 are input as 1 through N0T18g, and 0 is OR1.
Output to 8f. As a result, from OR18f to condition state 1
And is stored in the condition state storage means 15 (603).

Further, for example, if the operation signal OFF is input, the processing as shown in FIG. 15 is performed (601,
604).

First, if the operation signal is turned on, and the bits 0, 1, and 2 of the condition state control regulation information storage means 17 are set to 0, 0, 1 and the condition state 0 of the condition state storage means 15 is set, the condition state control is performed. The AND 18i which inputs the bit 0 (0) of the regulation information storage means 17 and the operation signal OFF (0) outputs 0 to the AND 18j.

The AND 18k inputs the operation signal OFF [0] and the condition state [0] of the condition state control regulation information storage means 17 and outputs 0 to the NOT 18m and the AND 18n. Next, the AND 18j outputs 0 to the OR 18p, and the AND 18n outputs 0 from the OR 18p based on the bit 1 (1) of the conditional state control regulation information storage means 17 set to 0 by the NOT 18q and the 0 of the AND 18k. As a result, (0) is output from the OR 18p as the condition state, and the condition state storage means 15 is directly set to 0 (604).

The above processing of the condition state control means 18 is summarized as shown in FIG. 16. For example, in the illustrated arrow example, the bits 0, 1, 2 of the condition state control regulation information storage means 17 are 0, 0. , 1 and when the condition state of the condition state storage means 15 is 0, the condition state becomes 1 when the operation signal ON is input, and the condition state 0 becomes when the operation signal OFF is input next.

As described above, the condition state control means 18 determines the condition state to be set in the condition state storage means 15 in accordance with the setting of the bits 0, 1 and 2 of the condition state control regulation information storage means 17. Then, after setting the condition state in the condition state storage means 15, the operation condition determination means 16 is notified of the operation signal.

In the procedure shown in FIG. 17, the operation condition determination means 16 first extracts the condition state of the condition state storage means 15 and the operation condition of the operation condition information storage means 14 (701, 7).
02).

The operation condition information storage means 14 stores either 0, 1, or 2 as an operation condition for each operation signal as shown in FIG.

Next, the operating condition judging means 16 judges whether or not the operating condition of the operating condition information storing means 14 is 2, and if it is 2, it requests the operation output means 3 to output an operation (703, 703).
704).

Further, the operating condition is not 2, but the operating condition is 0.
And the condition state of the condition state storage means 15 is 0, an operation output request is made to the operation output means 3 (705, 7).
04). Further, the operating condition is not 0 or 2, the operating condition is 1, and the condition state of the condition state storage means 15 is 1.
At this time, an operation output request is made to the condition state storage means 15 (706, 704).

As described above, when the operation condition is 0 and the state of the condition state storage means 15 is 0, the operation output is requested, and when the operation condition 1 is 1 and the condition state storage means 15 is 1, the operation output is requested. . Further, the operation condition 2 unconditionally requests the operation output.

For example, if the operating condition stored in the operating condition information storage means 14 of the notified operating signal is 0, the bits 0, 1, 2 of the target operating signal in the condition / state control regulation information storing means 17 are If it is 010, the condition state control means 18 sets the condition state to 0, and the first operation signal is turned on / off to become the condition state 1 (left column in FIG. 16).

Next, in the condition state 1, the condition state storage means 15 causes the condition state 0 (FIG. 16) when the operation signal is turned on / off for the second time.
(Right column) is stored. At this time, the operating condition determination means 1
6 determines that the operation condition is satisfied, and issues an output request to the operation output means 3. This is after confirming the operation at the first time,
This is an example of a double-pressing operation such as a case of actually performing the operation by the second operation. The operation output means 3 outputs an operation output to the output device when an operation output request is made.

In the conventional operating device, the operation signal is output from the operation output means 3 with the operation signal ON / OFF being kept as it is.
According to the third embodiment, the condition state control means 18 sets the condition state 0 or 1 set in the condition state storage means 15 according to the setting of the bits 0, 1, 2 of the condition state control regulation information storage means 17. Decided. The operation condition determination means 16 compares the condition state 0 or 1 with the operation condition and determines whether or not the operation output is performed. Therefore, the operation condition of the operation output is determined for each operation signal, and the operation is performed according to the operation condition and the condition state, so that the erroneous operation is prevented, and the operator's burden is reduced without requiring the operator's judgment.

Next, a fourth embodiment of the present invention will be described with reference to FIG.

19 which are the same as those in FIG. 10 according to the third embodiment show the same or corresponding portions, and FIG.
Further, a process control device 19, a process state input means 20, and an operation output storage means 21 are additionally provided.

The process control device 19 controls the controlled object and inputs the process state into the process state input means 20.
Is output to. The process state input means 20 is
The process state is input from the process control device 19 and output to the operation condition determination means 16.

The operation output storage means 21 comprises a condition-satisfied action regulation information storage means 22 and a condition-unsatisfied behavior regulation information storage means 23. The condition-satisfied behavior regulation information storage means 22 stores the operation output contents when the operation condition is satisfied. The operation output information storing means 23 stores the operation output contents when the operation conditions are not satisfied.

First, when the operator inputs from the input device 5, an operation signal is input to the operation input means 2. The operation input means 2 and the condition state control means 18 operate in the same manner as described in the third embodiment.

The operating condition judging means 16 fetches the condition status of the condition status storing means 15 and the plant status from the process status inputting means 20 in the same manner as described in the third embodiment, and the operating condition information storing means. The operating condition is compared with the operating condition of No. 14 and whether the condition is satisfied or not is determined, and the operation output unit 3 is notified together with the operation signal.

Here, the operation condition information storage means 14 operates whether the condition state of the condition state storage means 15 is used as the operation condition state or the process state of the process control device 19 is used as the operation condition state. It is stored for each signal, and together with this, the condition state of the operating condition is also stored. Further, when the process state is used, the point number of the process to be the condition state is also stored.

Here, for example, a case where there are pumps A and B controlled by the process control device 19 to configure a duplex and normally one of the two pumps is operating will be described in detail. To do.

First, in order to determine to which pump the operation output is to be made, the process condition is stored in the operating condition information storage means 14 as the operating condition, and which pump is being used is determined. The point number of the indicated process signal and the condition state when the pump of A is in use when the state indicated by the point is 0 are stored as 0.

Then, when the operation signal is notified, the operation condition determination means 16 determines the process state corresponding to the point number stored in the operation condition information storage means 14 via the process state input means 20. It is further input, and it is compared and judged whether or not it is the same as the condition state.

The operation condition judging means 16 is the operation output means 3
To the control signal together with the operation signal. When the operation output means 3 is notified of whether or not the operation condition is satisfied and the operation signal thereof is notified, when the operation condition is satisfied, as shown in FIG.
The operation output content (for example, A pump startup) stored in the condition-satisfied operation regulation information storage unit 22 of the operation output storage unit 21 having the configuration shown in FIG. 0 is output to the output device 6, and when the operation condition is not satisfied, the operation is performed. The operation output content (for example, B pump startup) stored in the condition unsatisfied operation regulation information storage unit 23 of the output storage unit 21 is output to the output device 6.

The content of the operation output corresponding to the operation condition of the operation signal is stored in the condition-satisfied operation regulation information storage means 22 and the condition-satisfied behavior regulation information storage means 23 of the operation output storage means 21 shown in FIG. Is remembered.

For example, according to the judgment of the operation condition judging means 16, the pump A is started when the condition is satisfied, and the pump B is started when the condition is not satisfied, for example, when the pump B fails. The condition-satisfied operation regulation information storage means 22 stores the start-up operation output of the A pump as the operation output content to the A pump, and the condition unsatisfied operation regulation information storage means 23 stores the operation output content to the B pump. , B pump starting operation output is stored. As a result, the operation output means 3 outputs the start operation output of the A pump to the output device 6 when the condition is satisfied, and outputs the operation output of the B pump to the output device 6 when the condition is not satisfied.

According to the fourth embodiment, the operating condition judging means 16 establishes a condition based on the condition state storing means 15 including the process state in the operating condition preset in the operating condition information storing means 14 and the corresponding process state. Alternatively, the failure can be determined. Therefore, when the operation state or the plant state is not the prescribed state, for example, when the plant equipment fails, the operator automatically determines what should be output by one operation without performing a special operation, and outputs the operation output. It is possible to prevent the malfunction of the operator and reduce the burden on the operator.

Next, a fifth embodiment of the present invention will be described with reference to FIG.

In FIG. 21, which is the same as the conventional example shown in FIG. 29, the same reference numerals indicate the same or corresponding portions. The difference between the two is that the step validity determining means 24, the next step setting information storage means 25, and the next step setting means 26 are the same. And the step information storage means 27 are additionally provided.

When the step validity determining means 24 determines from the step information storing means 27 that the step information and the corresponding range of operation information in the acceptance range information storing means 1 is a valid operation signal, it operates the next step setting means 26. Notify the signal and operating procedure.

The next step setting information storage means 25 stores information for each operation procedure in advance for each group according to the operation procedure. The next step setting means 26 determines the next step setting information storage means 25 from the set of the notified operation signal and its operation procedure.
The corresponding step information from the step information storage means 27
Set to. The step information storage means 27 stores the next step information by the next step setting means 26.

Next, the operation of the fifth embodiment will be described with reference to a concrete example.

First, as shown in FIG. 22, there are three operating procedures (steps). First, one operating procedure (step 1) system selection of system A and system B, followed by two operating procedure (step 2). ), The valve is selected from among the X valve, the Y valve, and the Z valve, and finally the opening / closing operation is selected as three sets of operation procedures (step 3).

Here, as shown in FIG. 23, in the acceptance range information storage means 1, as the acceptance range of each operation procedure (step), "A system selection signal" is stored in one operation procedure set (step 1). "B system selection signal", "X valve selection signal", "Y valve selection signal" for the two operation procedures (step 2),
The “Z valve selection signal” and the operation procedure 3 sets (step 3) store the “open selection signal” and the “close selection signal”.

First, the operation information input from the input device 5 is input to the step validity determining means 24 via the operation inputting means 2. The step validity determination means 24 extracts the position of the currently valid operation procedure (step) stored in the step information storage means 27 by the processing procedure shown in FIG. 24 (801, 802).

The step information storage means 27 is operated in the same order as the storage order of the operation signal reception range for each set of operation procedures (steps) stored in the reception range information storage means 1 as shown in FIG. Information indicating validity / invalidity of a procedure (step) is stored as 0 being invalid and 1 being valid.

As a result, the step validity judging means 24
Retrieves the position of the valid operating procedure (step) from the step information storing means 27, and takes this position as the set sequence of the operating procedure (step) stored in the receiving range information storing means 1, and retrieves the information of the receiving range. It is determined whether the input operation information is a valid operation signal (804).

When a valid operation signal is input, the next step setting means 26 is notified of a set of valid operation signal and its operating procedure (step) (80).
5). This process is performed for all steps (8
06, 807).

Then, the next step setting means 26 is operated by the operation shown in FIG.
When the process shown in FIG. 6 is performed and the set of the operation signal and its operation procedure (step) is notified, the next step setting information storage means 2 is generated from the notified set of operation procedure (step) and the operation signal.
The information having the same configuration as the corresponding step information storage means 27 of 5 is taken out and stored in the step information storage means 27 (901).

Here, the next step setting information storage means 25
27 shows whether or not information is stored in the order of operation procedures (steps) as shown in FIG. 27, and for each operation signal received for each set of operation procedures (steps), input is validated by the next operation. Information is stored for all operating procedures with the same configuration as the step information storage means 27 of FIG.

For example, FIG. 27 shows which of the following operation procedures is valid after the operation signal 1 is operated in two operation procedures.

Next, a valid operation procedure is set as shown in FIG. 28, and a request for operation output is made to the operation output means 3 (902). When receiving the operation output request, the operation output means 3 outputs an operation output such as a valve opening / closing command to the output device 6.

For example, in FIG. 28, the next valid operating procedure (step) is shown. There are operating procedures (steps) 1, 2, and 3 sets for bit 0, 1, 2, and first, operating procedure (step). ) When either one of the A system selection operation signal and the B system selection operation signal is operated, one operation procedure (step) and two operation procedures (step) are valid, and three operation procedures (step) are invalid Is shown.

Next, in the two operation procedures (steps), all the operation procedures are valid, and in the three operation procedures (steps),
It shows that only one set of operating procedures (steps) is valid.

According to the fifth embodiment, for example, in FIG.
When the system or the B system is selected, the valve selecting operation in the next step becomes effective, and when the X valve, the Y valve, or the Z valve is selected, the selecting operation of the opening / closing operation instruction in the next step becomes effective. Therefore, the operation content becomes the same as when the operator operates the operation switch of the conventional operation panel, and when one operation is performed, the operation of the next step becomes effective, so that the operator's erroneous operation is prevented and the operator's operation is prevented. The burden can be reduced.

[0119]

According to the first aspect of the present invention, the next operation signal can be invalidated during the priority processing when the operation signal for the priority processing is input. Therefore, the prioritized processing similar to the operation switch of each operation panel of the conventional operation device can be individually set for each operation signal to prevent erroneous operation and reduce the burden on the operator.

According to the second aspect of the invention, when there is an operation signal already selected, the next operation signal can be invalidated until the operation output of the operation signal is completed, but the operation already selected. Even if there is a signal, a specific operation signal can be accepted as a rear priority and an operation output can be performed. Therefore, like the conventional operation switch on the control panel, set the rear priority individually,
Since priority processing can be performed, erroneous operation of the operator can be prevented and the burden on the operator can be reduced.

According to the third aspect of the invention, it is determined whether or not the operation output is performed by comparing the condition state with the operation condition. Therefore, the state of the input operation signal is not output as it is, but the operation condition of the operation output is determined for each operation signal.
Since the operation is performed according to the operating condition and the condition state, erroneous operation is prevented, the operator's burden is reduced without requiring the operator's judgment.

According to the fourth aspect of the present invention, whether the operating condition is satisfied or not is determined by the determination based on the present condition state, the plant state and the operating condition, and the operation output means is operated according to the operation content in response to the determination. Output is requested.
Therefore, when the operation state or the plant state is not the prescribed state, it is possible to automatically determine the operation output even if the operator does not determine the operation output, and prevent the operator's malfunction and reduce the operation load. it can.

According to the fifth aspect of the invention, when a certain operation procedure is selected, the selection operation of the next operation step becomes valid, and when that operation is selected, the selection operation of the next operation step becomes valid. Therefore, the operation content becomes the same as when the operator operates the operation switch of the conventional operation panel, and when one operation is performed, the operation of the next step becomes effective, so that the operator's erroneous operation is prevented and the operator's operation is prevented. The burden can be reduced.
